Diclinic bar casting mold

Technical field

This utility model relates to plastic machining mold.

Background technology

Injection moulding is a kind of method that industrial products produce moulding. Product generally uses rubber injection mold and plastic injection. Injection moulding also can dispensing molding die platen press and casting die. It is that thermoplastic or thermosetting plastics utilize mould for plastics make the main former of variously-shaped plastic that injection (mo(u)lding) machine (is called for short injector or injection machine), and injection moulding is realized by injection machine and mould. Product is widely used in: the industries such as mobile phone, laptop computer, multiple plastic shell, communication, micro machine, computer, electrical equipment, electronics, toy, clock and watch, lamp decoration, locomotive. Injection mold is the instrument producing plasthetics, is also to confer to the instrument of plasthetics complete structure and accurate dimension. A kind of processing method that injection mo(u)lding is used when being and produce some complex-shaped parts in batches, refers specifically to by high pressure, the material melted that is heated is injected die cavity, after cooled solidification, obtains formed products.

Along with the day by day maturation of injection molding technology, increasing plastic cement products can be produced by injection moulding, and simultaneously that the requirement of mould is also more and more higher, mould is generally divided into dynamic model and cover half, treats foundry goods molding, and dynamic model moves opens die cavity, is exposed by foundry goods and then takes off; For the shaft-like foundry goods that some are thinner, if simple adopts dynamic model positioned opposite and the cover half demoulding, foundry goods unbalance stress can be made, it is easy to cause casting deformation to be torn or directly rupture.
