AI Technical Summary

Technical Problem

In existing injection molding processes, weld lines are difficult to avoid, and localized heating may prolong the injection cycle, especially in cases with thin runners or where localized heating is required.

Method used

Adjustable heating elements are used to locally heat and rapidly cool the mold cavity wall, avoiding the formation of weld lines. The heating elements create cooling gaps on the cavity wall to quickly dissipate heat energy and ensure rapid cooling.

Benefits of technology

It effectively reduces or eliminates weld lines, maintains the efficiency of the injection molding cycle, enables rapid heating and cooling, and is suitable for injection molded parts with high-gloss surfaces.

Abstract

A heating device for locally heating the wall of an injection mold cavity, the heating device comprising: a base plate; an actuator located on the base plate and for performing linear motion; a heated mold plate connected to and driven by the actuator to perform linear motion in a direction toward and away from the wall of the injection mold cavity; wherein the heated mold plate is located below the base plate and the actuator is located on top of the base plate, and wherein the base plate includes an opening through which a pin extends for transmitting linear motion from the actuator to the heated mold plate.
