搅拌机的模具设计及工艺设计 摘 要 本设计说明书简要说明了搅拌机底座注射模具的设计过程。首先从该塑件所选用的材料ABS、塑件的精度要求、生产批量等几个角度进行分析，确定模具的成型方案。具体内容包括注塑机的选择、型腔数目的确定、塑件的排位、分型面的确定、模具强度、成型零件的设计、常用的结构件的设计、侧向分型抽芯机构的设计、脱模机构、浇注系统、模具温度及冷却系统的设计等，并对在设计中选用的一些常用的标准件进行了说明。其中主要针对模具的型芯、型腔的设计进行了认真的分析和说明，为提高模具的设计水平提供了有力的理论依据。型芯的计算按制品的平均收缩率计算，同时还对一些特殊的部位的尺寸进行必要的工艺分析，还有一部分尺寸则根据实际生产过程中得到的一些经验的数据确定。 关键词：ABS；脱模机构；冷却系统；浇注系统；模具设计；注塑模 ABSTRACT This design instruction booklet briefing cap has injected the mold the design process. First from should model the material which an institute selects ABS, models the precision request, the production batch and so on several angles carries on the analysis, the definite mold takes shape the plan. The concrete content including the casting machine choice, the cavity number determination, models the platoon position, divides the determination, the mold intensity, takes shape the components design, the commonly used structural element design, the good position design, the drawing of patterns organization, pours the system, the mold temperature and the cooling system design and so on, and to some commonly used standard letters which selected in the design has carried on the explanation. Mainly aimed at the mold the core, the cavity design has carried on the earnest analysis and the explanation, for enhanced the mold the design level to provide the powerful theory basis. The core computation according to the product average shrinkage computation, meanwhile carries on the essential craft analysis to some special spots sizes, but also some part of sizes act according to some experiences data determination which in the actual production process obtains. Keywords：ABS; come off the mechanism of model ; cooling system ;gating system ; mold design; injection mold 目 录 摘 要 I ABSTRACT I 目 录 I 1 绪论 1 1.1塑料成型与注塑模具 1 1.2国内外相关发展状况 2 1.2.1国内发展状况 2 1.2.2国外发展状况 3 1.2.3中国与国外先进技术的差距 3 1.3塑料模具发展走势 3 2 塑件材料分析与方案设计 5 2.1塑件的工艺分析 6 2.1.1塑件的材料 6 2.1.2 ABS的基本特性 6 2.1.3 ABS的成型特点 6 2.1.4 ABS的主要用途 6 2.1.5 ABS的注射成型工艺参数 6 2.2塑件
