AI Technical Summary

Technical Problem

When there are deep grooves in the light strip, the air in the mold cavity cannot be discharged in time during demolding, which requires a greater external force to push it, and may cause scratches or deformation on the surface of the light strip.

Method used

An injection molding demolding device for automotive light strips was designed. The device uses a motor to drive a rotating rod and a cam mechanism, supplemented by an air pump and a one-way valve system, to allow gas to be ejected from the bottom of the light strip to assist in demolding. Impurities are filtered through a filter screen to prevent contamination.

Benefits of technology

This effectively reduces the adhesion between the light strip and the mold, avoids surface scratches and deformation, and ensures the integrity and precision of the light strip.

Abstract

The utility model relates to the field of lamp bar manufacturing, especially automobile lamp bar injection moulding demoulding device, including moulding box, still include fixed plate and demoulding assembly, through starting motor one drives rotating lever rotation, through rotating lever rotation drive cam rotates, when the part of cam protruding rotates with push board bottom and reaches the position, can make push board slide in the inside sliding slot, push board will go up the lamp bar in the lower mould and prop up, when cam rotates to the position of non protruding, through the action of spring makes push board reset, through starting air pump makes gas transport to the outlet pipe in connection hose and carries out the outlet, thereby can spray gas from the top of push board, the airflow acts on the lamp bar bottom, and the lamp bar is separated from the lower mould, and the adhesion of lamp bar and mould is reduced, can ensure that the airflow only sprays downward the mould direction through check valve, avoids the influence of gas reflux on air pressure, the filter screen filters the impurity in air, prevents the pollution lamp bar surface, thereby can conveniently take out the lamp bar from the lower mould.
