Plastic moulds are classified by structure
Plastic molds are generally classified according to the structure by mold frame, mold kernel, auxiliary parts, auxiliary systems, auxiliary Settings, and other parts of the dead Angle processing mechanism.
1. Mold base:
In general, we do not need to design, we can directly order from the standard mold frame manufacturer, greatly saving the design mold required time, so it is called plastic mold standard mold.It constitutes the most basic framework of the plastic mold.
2. Mold kernel:
The mold kernel part is the core part of the plastic mold, which is the most important part of the mold.The forming part of the plastic product is inside the mold, and most of the processing time is also spent on the mold.However, compared to some of the simpler moulds, it does not have a kernel part, and the product is formed directly on top of the template.The early plastic mold is mostly like this, relatively backward.
3. Auxiliary parts:
The commonly used auxiliary parts of plastic molds include positioning ring, injector bushing, thimble, grasping pin, support pillar, ejector plate guide pillar guide sleeve, garbage pin, etc. Some of them are standard parts, which can be ordered together when ordering formwork and some of them need to be designed by themselves.
4. Auxiliary system:
The auxiliary systems of the plastic mold are as follows: pouring system, ejection system, cooling system and exhaust system.Sometimes there is a heating system in some molds because the plastic material used is heated at a high temperature.
5. Auxiliary Settings:
The supporting of the plastic mold is provided with hoisting ring hole, KO hole (top bar hole) and so on.
6. Dead Angle treatment structure:
When a plastic product has a dead corner, the mold also has one or more structures that handle the dead corner.Such as sliding block, inclined top, hydraulic cylinder and so on.In most domestic books, this kind of mechanism for treating dead corners is described as the "extraction mechanism".
In fact, the plastic mold is not difficult, no matter how the plastic product changes, for the mold to form this plastic product, its structure is nothing more than the above aspects.And the difference between the molds is whether the mold is big or small?The locations or modes of various auxiliary parts, auxiliary Settings, and auxiliary systems are different.The method, structure, size, etc. of treating dead Angle has changed.Of course, to make the design of mold processing simple, easy to assemble, long life, price moderate, forming products good, design experience is particularly important.Good experience, can deal with the problems in design, processing, treatment of the change is also more confident.
