AI Technical Summary

Technical Problem

When plastic products with metal PIN needle inserts are injection molded, the PIN needle inserts have less installation positioning, which leads to unstable and easy drop and is difficult to adapt to normal production needs.

Method used

A plastic mold including a male template and a female template is designed. By setting a fixed plate, a female mold insert sleeve and a template insert on the female template, and movable inserts and insert springs are provided in the male template to form a movable mechanism of the insert needle to ensure the stable installation and positioning of the insert needle.

Benefits of technology

By adding a movable insert mechanism, the problem of less and unstable installation and positioning of the PIN needle insert is solved, avoiding the risk of unstable installation of the PIN needle insert easily falling and hitting the mold, and ensuring the normal production progress.

Abstract

The utility model discloses a plastic mold beneficial to embedding and injection molding of an insert, which comprises a male mold plate and a female mold plate, an upper fixing plate is arranged on the female mold plate, a female mold core is arranged in the female mold plate, a male mold core is arranged in the male mold plate, the male mold plate is positioned below the female mold plate, and an insert needle is vertically arranged between the female mold core and the male mold core. A female mold insert sleeve is vertically arranged in the female mold core, the upper end of the insert needle is located in the female mold insert sleeve, a mold plate insert is vertically arranged in the female mold insert sleeve and located over the insert needle, a movable insert capable of ascending and descending is vertically arranged in the male mold core and located under the insert needle, an insert spring is arranged in the male mold plate, and the movable insert is located under the insert needle. The insert spring is located below the movable insert, the lower end of the movable insert abuts against the insert spring, and a die plate spring is arranged between the female die plate and the upper fixing plate. The plastic mold beneficial to embedding and injection molding of the insert solves the problem that the insert needle is less in mounting and positioning and unstable during injection molding of a plastic product with a metal needle insert.
