The choice of parting surface, consideration should be given to decrease due to ejection angle caused by childrens garden tools sets parts size end size difference, if the mould nest in male die, because the draft caused by plastic parts size end size too big difference, when the plastic parts with ejection angle larger does not allow, using this structure makes the demoulding difficulty, if the plastic parts appearance without strict requirements, can be parting selected in the plastic part, the children garden tools can be used to release angle is small in favor of release to ensure that the plastic parts surface requirement: the plastic garden tools set plane as far as possible to choose in does not affect the appearance of parts of plastic parts and plastic parts appearance requirements.
The technical specifications of the injection machine account:
The clamping force to consider: as much as possible to reduce the projection area of plastic parts in parting face of. When the maximum injection area projection area of plastic parts in the parting plane close to close to the injection machine, has produced the overflow may, machinery blade mould parting surface size in the guarantee does not overflow case, children garden tools should be reduced as much as possible the parting surface contact area, to increase the plastic snow scoops pressure die to face, to prevent the flash, and simplify the parting surface processing.
Template space considerations: the parting surface is determined to ensure that the male and the female mould opening stroke of the shortest.

Classification and introduction of plastic garden tools
Plastic garden tools and hoe is somewhat similar, just some action end more slender, used to dig more childrens garden tool land.
Plastic garden tools, the pure hand tools can be mowing, mowing, harvest. Sickles was invented in about 500 BC, and in plastic garden tools sets and thirteenth Century in europe. The first is mainly used for mowing grass, modern science and technology developed in the plastic snow scoops , all of these have now largely been motor lawnmower and combine replaced, there have been some places still use a sickle.

Garden tool set style and color
Tool set garden styles and color also changed the monotonous, added with chic modelling, be riotous with colour products. Growing flowers, vegetables and so on to some workers of the new kids garden tool set of leisure, not only can exercise the body, but also improve the environment, the harvest of harmless vegetables. These labor, for the working people is entertainment, as entertainment, buy says hand tools is inevitable. Therefore, hardware city market of various high-end garden tools start Repeng, many consumers from the concept of use rises for fashion, exquisite.
Now people attach great importance to ecological environment, some plastic snow scoops or a hospital before and after the house, as far as possible to cover with green open space. For example, trees, and flowers, and a lot of people like yourself, not only the conservation of the living environment, but also can exercise the body. This part of consumers, often do not care about the price of the products, they value the product brand, quality, performance, the so-called high-end consumer demand for high-end products, and this is the reason. There are many companies, the unit demand for garden tools are no childrens garden tools used to visit, but the pursuit of convenient operation, energy saving, not only to avoid the waste of labor, and high-end garden tools although the price expensive than ordinary, but because of its long life, energy saving effect is obvious, is not lost.
Along with the concept of landscape greening win support among the people, gardening tools also gradually into the homes of ordinary people's life, become common, universal.

Principle children garden tools machinery blade
Selection of parting surface consideration principle:
1 the quality of plastic parts considered
Ensure the dimension precision of plastic parts
B. select the parting surface, consideration should be kids garden tool set to reduce the draft caused by plastic parts size end size difference, if the mould nest in male die, because the draft caused by plastic parts size end size difference is too big, when the plastic parts with draft larger does not allow, the structure that is difficult, if children garden the appearance of the tools without strict requirements, but will die in the plastic part, it can be used to draft the smaller to release to ensure that the plastic surface requirement: parting surface as plastic garden tools set without affecting the appearance of the plastic parts and plastic parts appearance requirements.
Technical specifications of 2 injection machine account:
A. mode locking force is considered: as much as possible to reduce the projection area of the plastic parts in the parting plane. When the maximum injection area projection area of plastic parts in the parting surface is close to close to the injection machine, has produced the overflow may, machinery blade die parting surface size to ensure no overflow condition, it should be possible to reduce the parting surface contact area, contact pressure to increase the die surface, prevent overflow, and simplify the parting surface processing.
The B. template spacing to consider: parting surface is determined to ensure that the male and the female mould opening stroke the shortest.
Consider 3 mechanical blade structure
A. try to simplify mold parts
A. for children garden tools release, should make the plastic parts in the mold in the mold as much as possible, as long as the plastic snow scoops binding force and the male die than plastic binding force to piece and the female die, as far as possible the binding force between the plastic and die so ugly, but don't put the plastic parts with blade and mechanical force on the male die.
B. when the plastic parts of the shape is simple, but the inner shape more complex hole or holes, plastic molding must remain in the mold, the mold fossa can be located in the master mold, the mold can be used to push plate plastic parts, if the mould nest in the public mode, the difficulty of stripping.
C. when a metal insert, because insert will not shrink wrapping die, so die wo should be located in the mold, or opening the mould in plastic parts mold, the difficulty of stripping.
D. if the plastic mold is symmetrically distributed, should be forced to remain in the public mode of plastic parts, pipe jacking demoulding.
B. side core pulling mechanism considering.
A. should try to avoid the side core pulling mechanism, if cannot avoid the side core pulling, should make the core pulling as short as possible.
B. due to inclined sliding block mould locking force is small, for large plastic parts projected area larger, the plastic leaf rakes parts projection area of parting surface on the main plane in the male and the female mold clamping, and will die projection area smaller surface as a side parting surface, otherwise the slanting slide lock locking device must be very large, or the lock is not tight and flash C. convenient pouring system arrangement: the parting surface is determined not to impede the normal opening gating system.
D.: children garden tools in order to facilitate the exhaust is conducive to the discharge gas, the parting plane as far as possible with the material flow end overlap.
E. is easy to insert placed: when parting surface after opening, to have a certain space insert.
Simplify the overall structure of F. mechanical blade, minimize the number of parting surface, as far as possible the use of flat type surface. Consideration should also be given to mechanical blade is easy processing, easy to take out the finished products, and the parting surface should be chosen in the product line.
4 mechanical blade manufacturing difficulty consideration: to ensure mechanical blade easy mechanical processing.

Differences in the plastic garden tools blade
Before using the plastic garden tools blade, we must determine a fact, the blade and the childrens garden tool has a great difference.
The next is the fact that the number of cutting edge of each blade is relatively less. In many shops, car blade is triangular or rhombic. The number of the best combination of cutting edge (mechanical blade) and cutting edge strength (diamond blade) the possibility of convex triangular blade provides apparent in many workshops are not enough cognition.
In twentieth Century 70 time, the best childrens garden tools is to use large size, strong blade. Hard alloy used in that era is hard, but the toughness is not good enough. Plastic garden tools blade strength by its size (large blade = thick blade = high strength blade) to ensure. Three times a blade of the cutting edge length of at least more than cutting depth. Two things have changed at the same time. On the one hand, the average cutting depth for turning has been significantly reduced. A study carried out by the seco tools that average cutting depth, the plastic snow scoops is about 2.5~3mm. On the other hand, the fourth generation of hard alloy today has good toughness, but also its hardness (wear) higher. This means that for today's blade, the relationship between the cutting edge length and the cutting depth can change. The latest generation of blade geometry is suitable for the new situation.

Prospects and performance of garden tool set
Use of garden tool set and other electric tools, or even go beyond the body, it is seven exquisite, long service life, high safety, and energy saving. The pneumatic childrens garden tools sets in the market as a whole, its specifications are more complete, such as air chisel, gun drilling, polishing machine, impact wrench, but due to its market price is much higher than ordinary electric tools, which is caused by pneumatic tools have not been widely adopted by one of the main reasons.
Garden tool set is promising, mainly in three aspects:
1.garden tool set the ability to work, compared with ordinary electric tool is more suitable for the long time work.
2.garden tool set environmental adaptability. Pneumatic tools, water resistance, no spark, can adapt to all kinds of bad or poor environment.
3.plastic garden tools set low maintenance cost. Pneumatic tool is used in air pressure pipeline equipment, electric tools such as replacement parts without.
Start the manufacturing industry and the technology started late, after 10 years it has got great development, garden tool set with high quality, high life, high speed, high output power and high precision characteristics, was soon applied to various industrial sectors, and play a significant benefit. With the rolling, drawing, casting, machining, assembly, cleaning a burr and detection technology to raise the level of pneumatic components, the appearance and inner quality will also continue to improve. Industrial ceramics, high performance soft magnet, plastic new material has on the new product application, and application of new materials in the future there will be more and more.
To meet the needs of different consumer demand, garden tool set forward following direction:
1 electromechanical integration direction. In order to childrens garden tools the predetermined target, conversion between the gas, electrical signals.
2 precision. In order to make more precise cylinder positioning, using sensors, proportional valve to realize precise feedback control.
3 combination, intelligent direction. In the material handling process, has used a combination of cylinder, the swing cylinder and vacuum sucker. While mobile small items are the two cylinder guide respectively by X, Y axis combination, also equipped with electromagnetic valve, controller, compact structure, small occupied space.
