文档介绍：灭火器塑料注射模设计
摘要
塑料模具是塑料加工工业中和塑料成型机配套,赋予塑料制品以完整构型和精确尺寸的工具。本课题主要是针对灭火器端盖的注塑模具设计,灭火器端盖具有重量轻、易清洁、耐腐蚀老化、强度高、使用寿命长,制作方便、价格低廉等特点。本次设计主要是根据塑件的外形及塑料的工艺性,确定模具的分型面,浇注系统、选择了注射机、计算了模具成型零件的尺寸,并设计了托板等其他零部件。本设计中采用点浇口注射,利用斜导柱抽芯机构和和斜滑块抽芯机构进行侧向抽芯,推管完成脱模。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,运动可靠,结构合理。

Fire extinguisher in plastic injection mold design
Abstract
Plastic mold is the plastics industry and plastic molding machine form plete set, give plastic products plete configuration and accurate size of tools. The main topic is covered in mold design for the fire extinguisher, the fire extinguisher covered with a light weight, easy to clean, corrosion-resistant aging, high strength, long service life, making easy, low prices and so on. The design is based mainly on plastic parts and plastic form of the process to determine the mold surface, gating system, select the injection machines, molding parts to calculate the size of mold, and the design of the Supporting Plate and ponents. This design with some runner injection, using the oblique guide column core-pulling mechanism and and oblique slippery pieces of core-pulling mechanism for lateral core-pulling, push the finish stripping. Through the entire design process that can be achieved in the mold plastic parts required in this process,movement is reliable, the structure is reasonable.
