摘要
模具是工业生产中使用极为广泛的主要工艺装备,它是当代工业生产的重要
手段和工艺发展方向,许多现代工业的发展和技术水平的提高,在很大程度上取
决于模具工业的发展水平。本论文主要介绍了加热器底座塑料注塑模具的设计。
设计中首先通过分析塑件的形状及工艺特性,选择了合适的模具设计方案;
其次是对注塑机的选择,包括注射机的初选和注射机有关参数的校核,并确定了
注射机;再次完成模具的结构设计,包括分型面的选择和确定、型腔数目的确定
及型腔的排列、浇注系统的设计、成型零件结构设计、抽芯机构设计、推出机构
的选择、冷却系统的设计、标准模架的选择。最后对成型零件尺寸进行计算,确
定工艺参数。
采用此模具能够保证塑件尺寸外形以及表面要求,而且成本低、结构简单、
开模容易、效率高,具有较强的实用性。

Abstract
Mold is widely used in industrial production the main technological equipment,
It is an important means of modern industrial production and process development
direction ,Many modern industrial development and the improvement of the technical
levels ,Largely depends on the development of die and mould industry level. This
paper mainly introduced the plastic injection mold insurance seat of design.
First through analysis in the design of plastic parts, process characteristics and
shape ,choose the proper mould design,Second is the choice of injection, mcluding
injection machine of primaries and injection machine related parameter
respectively ,To determine the injection plete the die structure design
again ,Enclose the choice and determination parting ,Cavity number of determining
and cavity arrangement ,The design of gating system ,Molding parts structure
design ,Core-pulling mechanism design, selection of launch institutions, cooling
system design, standard formwork choice ,Finally calculated for molding parts size,
determine the process parameters.
Using this mold can guarantee plastics dimension appearance and surface
requirements , And low cost, simple structure and easy to open mold, high efficiency,
with strong p
