The structure is a particular form of the material through a certain way of forming a kind of industrial products, but also be able to mass produce a certain shape and size requirements of industrial products as a production tool parts. This article describes the Dong an car bumper lamp double-cavity injection mold design method and the specific design process, The plastic parts for the Harbin Qi Plastic Automotive Trim Co., a standard sample, the sample structure through process analysis, select the type of injection machine, injection mold to determine the overall structure. Through the material properties used in theoretical calculations and aggregate data to determine the mold gating system, core mechanism, guide mechanism, the top out of institutions, reset rod, such as cooling systems, and mold design. Use the standard mold, using CAD software to draw two-dimensional drawing and injection mold parts drawing the overall assembly drawing. Which, as the plastic parts on both sides of the wall has holes, so core mechanism design is the design of the important and difficult. The analysis uses the side bevel pillar method of pumping effectively solve this difficult. 目 录 摘要 I 第1章 绪论 1
