一种单腔双色多功能注塑模具设计

Mold Design with Single-Cavity for Bi-color Molding and Family-Layout Multifunction for Button-base

介绍了一种特殊的单色、双色集成式家族两板注射模具。模具的布局为1模2腔,其中的一个单色模腔用于塑件的单色注射成型,另一个单腔双色模腔用于塑件的双色注射成型。单腔双色模腔只用一个模腔即能实现塑件的双色注射成型,其功能实现的方式为:在单色模腔的基础上,通过改变型腔镶件的形状及位置、以及第二胶浇口成型件的位置,达到单腔进行双色注射成型的目的。结合浇注系统的改造,模具能实现5种注射成型功能,分别为:单色塑件单腔注射功能、单色塑件双腔注射功能、单腔双色注射功能、单色+双色家族式注射功能,以及单模中注射两种不同颜色的同款塑件。模具结构新颖,简单实用,能有效降低多要求注射成型塑件的模具制造成本,有较好的设计参考价值。

This paper reported an introduction for a special single-color and bi-color integrated family two-plate injection mold.The layout of the mold was composed of 1 mold and 2 cavities.One cavity was used for monochromatic injection molding of plastic parts,and another was used for monochromatic injection molding of plastic parts.A combination of single-cavity and bi-color mold cavity can realize the bi-color injection molding of plastic parts with only one mold cavity.This function can be realized through changing the shape and position of the cavity insert and the position of the second rubber gate molding part on the basis of the single-color mold cavity.In this case,the purpose of single cavity and bi-color injection molding can be achieved.Combining with the transformation of the gating system,this mold can realize five injection molding functions,including the single-cavity injection function of single-color plastic parts,the double cavity injection function of single-color plastic parts,the double cavity injection function of single-color plastic parts,the singlecolor plus bi-color family injection function,and the injection of two different colors of the same plastic parts in single mold.The mold structure is novel,simple and practical.Such a design can effectively reduce the manufacturing cost of injection molding parts with multiple requirements and therefore provides a reference for the design other molds.
