Abstract

The invention discloses a secondary injection molding method for toothbrush handles, comprising the following steps of: (1) arranging a molding injection machine for performing injection molding of a toothbrush body; (2) arranging an encapsulating injection machine for performing secondary encapsulating injection on the toothbrush body to obtain the finished product; and (3) arranging a control system which is respectively connected with the molding injection machine and the encapsulating injection machine for controlling the operating modes thereof. The invention also discloses a system for implementing the method. The method provided by the invention can realize secondary injection molding on the basis of not changing the existing structure of the mold, so that the production cost is effectively reduced and the product quality is good. The system provided by the invention has a simple and reasonable structure, combines the molding injection machine and the encapsulating injection machine, realizes secondary injection molding, has high efficiency and quick speed, greatly improves the production efficiency and the product percent of pass, has high degree of automation, and greatly reduces the labor intensity.

Description

technical field [0001] The invention relates to the technical field of fixtures, in particular to a secondary injection molding method for a toothbrush handle and a system for implementing the method. Background technique [0002] With the continuous improvement of people's living standards, the styles of consumer products are becoming more and more diversified. They must not only have beautiful appearance and exquisite design, but also quickly meet market demand. Two-color injection molding (also called double-material injection molding) is a development in recent years. A trendy special plastic injection molding method, which can form products composed of two different colors or different plastics (such as a hard plastic and a soft plastic), which is actually an in-mold assembly or in-mold welding "Insert molding" process. The molding principle is to plasticize two different plastics in two barrels, and then inject them into the cavity of the mold to form plastic parts wi...
