Description

一种新型多穴数背光源透镜模具 技术领域
本申请属于注塑技术领域，尤其涉及一种新型多穴数背光源透镜模具。
背景技术
注塑是一种工业产品生产造型的方法。产品通常使用橡胶注塑和塑料注塑。注塑还可分注塑成型模压法和压铸法。注射成型机(简称注射机或注塑机)是将热塑性塑料或热固性料利用塑料成型模具制成各种形状的塑料制品的主要成型设备，注塑成型是通过注塑机和模具来实现的。
传统的透镜注塑模具采用64个注塑产品型腔，注塑模具产能小，制造成本高，因此，发明一种新型多穴数背光源透镜模具显得非常必要。
发明内容
针对上述技术问题，本申请提供一种新型多穴数背光源透镜模具，以解决现有的模具注塑效率低下，加工成本高的问题。
本申请实施例提供一种新型多穴数背光源透镜模具。该新型多穴数背光源透镜模具包括母产品区、模具、子产品区和型腔；模具上的型腔为阵列设计结构，模具上均布有8个相连通的母产品区，而每个所述母产品区由均布且相互连通的4个子产品区组成，每个所述子产品区由6个相互连通的型腔的环形阵列构成。
优选地，每个所述型腔的高度一致。
优选地，所述母产品区、所述子产品区、所述型腔上均设有唯一对应的编号。
优选地，注塑时，所述模具设置在水平面上。
