A, the Plastic Injection Molding parts: namely we usually say before, back mould CORE, is also the most closely linked with products; site
B, gating system: molten plastic from the nozzle to cavity flow can be divided into: mainstream way, split way, runner, cold material well;
C, guiding system: sure, before and after mode when shut the mould of relative positions, generally have guiding pole, guiding set, the necessary, ejection part also need to guide pin, guide sleeve positioning;
D, parting structure: is from mould plastic pieces of ejection device, commonly have: thimble, roof, cheese canister, etc.;
E, temperature control system to meet the injection forming process, to mold temperature requirements, in front and back mould for cooling channel;
plastic injection mould plastic mold injection F, lateral subtypes and lateral core-pulling: when the glue thing upside down with existing is not consistent demoulding direction when they have to use line structure of position, common form: the slider, lifter, core-pulling, etc.;
G, exhaust structure: common exhaust form has two kinds: exhaust slot, forming parts clearance. In order to eliminate the process of plastic injection mold in air and shaping
process produced gas, often set in parting surface air exhaust slot. Setting the principle is, vents are not affected when overflow anticipates the beatles, should as far as possible big spike the exhaust slot. And ejector, thimble, set piece is to use molding parts clearance exhaust.
