设计简介
摘要
本课题主要是针对喷头的模具设计,通过对所设计的塑件进行工艺的分析和方案比较,最终设计出一副注塑模具。该课题从产品结构工艺性,具体模具结构出发,对模具的型腔数、浇注系统、模具成型部分的结构、顶出系统、冷却系统、注塑机的选择及有关参数的校核、都有详细的设计。针对喷头的具体结构分析比较,该模具是点浇口的单分型面注射模具,由于喷头体积较小,所以应采取一模多腔结构,以实现高效率生产,本注塑模对型腔采用双排平衡式排列,以便采用平衡式浇注系统,其优点在于简化机构,使模具外形对称,从而可以得到尺寸正确,外表美观,物理性能良好的塑件制品。由于塑件具有侧向喷嘴,所以必须设置斜导柱,采用侧向抽芯的结构形式。

Abstract
 This topic mainly aimed at the mold design of shower nozzle. Through  the analysis and comparison of the plastic product which comes from your design , the plastic mold was designed. This topic came from the technology capability of product, the structure of the mold embarks,the Type cavity number. the pours system, the injection molding system and the related parameter examination have detailed design . Concrete structure specifically for the shower nozzle, be a mould's turn to be that mark of type injects a mould face to face count the running gate Shan, since shower nozzle volume is less therefore should adopt one multiple-cavity model structure, to realize high efficiency giving birth to a child, produce plastic articles by injection moulding the model adopt pair of rows to balance style arranging to type cavity , that whose merit is lain in makes mould external form symmetrical to adopt balance style to pour system, can get correct, have a fine exterior, Physical fine dimension function .Since moulding have a spray nozzle , therefore must interpose tilted guide pin, strengthen the structure form adopt side direction to take a core out.
 Key words :  Plastic mold, Cosmetics shower nozzle,Side direction to take a core out
