塑料手柄注塑模设计

Design of injection mould for the plastic handle

根据塑料手柄产品的结构特点,通过对产品建模分型的分析,介绍了注塑模的成型工艺过程,提出了模具采用斜导柱与滑块配合的侧向抽芯机构的脱模方式,解决了注塑成型后产品方形侧孔的脱模问题。模具设计时采用了标准模架结构,既缩短了模具的制造周期,又降低了模具的制造成本。经产品大批量的生产验证,该模具结构简单实用,产品质量好。

According to the structure characteristics of the plastic handle and the product modeling and parting analysis, the moulding process was introduced. Angle pin cooperating with side core pulling mechanism to demould solved the problem of square side hole demoul- ding after injection moulding. Standard mould base was used in the mould design. There- fore, manufacturing cycle was shorten and cost was reduced. By large quantities of produc- tion trests, the mould structure proves to be simple and practical that is able to produce good quality products.
