Problems solved by technology

However, in the injection molding mold, due to the difference in shrinkage between the insert and the plastic product, it is easy to cause residual stress in the plastic product after hot-melting, resulting in micro-cracks between the solidified plastic and the insert, affecting the entire insert The sealing effect of the product

Abstract

A mold for injection molding and an injection molding method. The mold for injection molding comprises: a mold body (10) and at least one vibration apparatus (20), the vibration apparatus (20) being arranged inside the mold body (10). The mold body (10) is provided with a mold cavity, a placement position being formed inside the mold cavity, the placement position being used to bear an insert (40). The vibration apparatus (20) is provided with a head end, the head end being arranged so as to face the insert (40), and when the vibration apparatus (20) generates a vibration, the head end is arranged so as to be able to drive the insert (40) to vibrate. One technical effect of the present invention is to reduce cracks between the insert (40) and a surface of an injection-molded casing (50) caused by internal stress, thus improving product quality.

Description

technical field [0001] The present invention relates to the technical field of injection molding, and more specifically, to an injection molding mold and an injection molding method. Background technique [0002] Plastic is a synthetic polymer compound, which is widely used in various industries such as electronics, automobiles, and medical treatment due to its excellent performance and easy processing and molding. In order to make injection molding products have a good appearance, while having both practicality and structural strength, insert injection molding is usually used. [0003] Insert injection molding makes use of the easy formability, heat resistance and electrical conductivity or mechanical properties of plastic to make an integrated product that combines with each other. Due to the advantages of low cost and unlimited types of insert materials, insert injection molding is widely used. [0004] Usually, the injection molding process includes three stages of fil...
