基于塑料挂钩底座注塑模具设计
摘要
本课题主要是针对挂钩底座的模具设计,通过对塑件工艺、结构等方面进行分析和比较,最终设计出一副注塑模。该课题从产品结构工艺性,具体模具结构结合具体情况对注塑模的浇注系统、模具成型部分、顶出机构、冷却系统等个方面进行详细的设计。通过整个设计过程表明该模具能够达到此塑件所要求的加工工艺。在设计时主要采用了应用Pro/e软件对挂钩底座制品进行了零件造型;使用CAD对挂钩底座进行模具设计。主要完成了对挂钩底座的工艺结构分析;塑件体积和重量的计算;注塑模的结构型式确定,浇注系统设计,推出机构的设计,型腔和型芯的结构设计,模具加热和冷却系统的计算,并按照比例绘制一张总装配图。
针对挂钩底座的具体结构,该模具是设计重点是在浇注系统及分型面的设计方面。模具采用一模两腔的单分型面点侧浇口进浇。其优点在于模具结构简单,提高制造精度,节约材料,大大提高了生产效率以及经济利益。

Based on the hook base injection abrasive tool design
Abstract
This topic mainly aimed at the base of the hook to the mold design, through the process and structure analysis parison, the final design out a pair of injection mold. The subject from the product structure craft, specific die bined with the specific circumstances of the gating system of injection moulds, mold molding part and ejection mechanism, cooling system and other aspects in detail design. Through the whole design process shows that the mould can achieve the plastic parts required processing technology. Mainly used in the design of the application of Pro/e software on the hook base products parts modelling; Using CAD to hook base for mold design. pleted on the base of the hook to process structure analysis; Plastic pieces of volume and weight calculation; Injection mold structure to determine, gating system design, launch mechanism design, the structure design of the cavity and core mold the calculation of heating and cooling systems, and according to the proportion to draw a general assembly drawing.
According to the specific structure of peg base, the mold design is key is in the gating system and the parting surface design. Mould with one module and two cavities single parting surface side of the gate into the water. Its advantage is that the mould structure is simple, improve the manufacturing accuracy, saving materials, greatly improves the production efficiency and economic benefits.
