Television foundation Injection Mold Design Based on

II

Pro/E

Abstract

Plastics are now in the automotive, electrical and mechanical, instrument, aviation and space industries and other countries and with people's daily lives in various fields related to a wide range of applications received.The method of forming plastics Although many, but the most important method is injection molding, the world production of plastic mold forming more than half of about injection mold. With the development of new plastics to the promotion of plastic instead of steel, plastic mold with a more broad prospects.

The design is based on the graduation project book of the task, to complete the TV base of a cavity of a mold injection mold design. According to the structure of plastic parts, technical requirements, to use the three-dimensional design software Pro / E for TV chassis design of the injection mold. Design elements include: the use of software to analyze Pro/e2.0 plastic parts of the injection molding process;using Pro/e2.0 software to calculate and design the structure of the mold; gating system design, select the surface; demoulding design introduced; cooling structure design. And through the cavity pressure and clamping force calculation, to select the injection molding machine, give the relevant process parameters. In order to reduce tooling costs, increase productivity and national standards for the components, the design of the use of standard parts.Include: injection mold mold standards; standard guide columns, such as lead sets. For those who have recommended the size of parts, the design of the recommended values are selected. M aking use of EMX4.0 softwares to choose to use a mold, using autoCAD software to draw diagram and work spare parts of the molding tool assemble diagram, using Word software to write design manual etc..

Keywords: Injection mold; base; sub-surface; cooling structure;
