AI Technical Summary

Technical Problem

Existing display frame injection molds result in low product ejection during demolding, making it difficult for robotic arms to grasp the product and hindering automated production.

Method used

A display frame injection mold was designed, which uses four movable mold cores that slide on both sides and front and back of the upper and lower mold cores. Combined with the inclined ejector rod and inclined guide rod mechanism, the display frame can be ejected around its entire circumference. The movable mold cores can be disengaged from the buckle to facilitate the gripping of the robot arm.

Benefits of technology

It enables full-circumference ejection of the monitor frame, simplifies the demolding process, facilitates automatic gripping by robotic arms, and improves production efficiency and automation.

Abstract

The utility model discloses an injection mold for a middle frame of a display, and aims to solve the problems that when an existing injection mold for the middle frame of the display is demolded, a product is ejected relatively low, so that the product cannot be grabbed by a manipulator easily, and automatic production is difficult to realize. The mold comprises an upper mold base, an upper mold base plate, an upper mold plate, a lower mold plate and a lower mold base which are sequentially arranged, a sprue is formed in the upper mold base, an upper mold core is installed on the lower surface of the upper mold plate, a lower mold core is installed on the upper surface of the lower mold plate, and four movable mold cores are arranged on the left side, the right side, the front side and the rear side of the upper mold core and the lower mold core in a sliding mode. During demolding, the displayer middle frame is ejected out through the inclined ejector rods on the upper surface of the movable ejector plate, and meanwhile, the inclined guide rods on the movable mold drive the movable block and the movable mold core to slide towards the outer side and break away from the displayer middle frame mold cavity, so that the periphery of the displayer middle frame is completely exposed, grabbing of a mechanical arm is facilitated, and automatic production is better achieved.
