增强聚丙烯电流线圈架成型工艺与注射模设计

Moulding Technology and Injection Mold Design of Reinforced PP Current Coil Former

针对制品两面抽芯的特点,通过比较分析制定了模具的侧向分型与抽芯结构形式。采用能解决一模两腔的两面抽芯问题的斜导柱滑块结构的模具结构,设计出电流线圈架注射模模具。经生产实践验证,该模具结构设计合理,型腔数目合适,分型面正确,抽芯动作平稳可靠,制品质量符合设计要求。

In accordance with the characteristics of 2-dimensional core pulling of product, the side parting surface and core pulling structure of mould was designed by means of comparison and analysis. A mould with an oblique guide pin scroll box structure was designed for the core pulling in two directions of a mould with two cavities. The results of production practice showed the design was reasonable, the numbers of the cavity were suitable, the parting surface was correct, the core pulling was stable and reliable, and the product quality was in account with the demands of design.
