Mould, indispensable in modern industry development and technological level improvement, is one kind of widely-used process equipment during mid-period of industrial production. According to statistics, moulding accounts for 75% of rough machining of industrial parts and 50% of precision machining. Mould can be classified as cold-punching mold, injection mold (or plastic injection mold), die casting mold, rubber mold and so on.
1. Introduction of Injection Mould
A. Molding parts/components: normally called as cavity and core, which are the closest part with plastic products.
B. Feeding/casting system: Runner for molten plastic to flow from nozzle to cavity. It is classified as the main runner, sub-runner, runner gate, cold slag well, etc.
C. Leading/Guiding system: The system, determining the relative position of cavity and core during clamping/mold closing, is normally made up by guide pin and guide bushing. the ejector plates also need positioning by guide pin and guide bushing.
D. Demoulding structure: It is the structure ejecting the plastic part from the mold. Commonly, it consists of ejector pin, ejector plate/stripper plate, ejector sleeve, etc.
