AI Technical Summary

Technical Problem

When the existing injection mold ejection mechanism fails to remove the product in time, the product will move downward and collide with the chamber, which may cause the product to fall and damage.

Method used

An ejection mechanism including a vertically sliding bearing plate, a hoist rod, a telescopic rod, a clamping block and a cylinder is designed. Through the cooperation of the clamping block and the chamber, the product can be avoided from collision with the chamber, and the product can be achieved by using the cylinder and cooling pipeline to achieve safe ejection and secondary cooling.

Benefits of technology

It effectively avoids collision between the product and the chamber during the ejection process, reduces the risk of damage, and improves the processing efficiency and safety of the product.

Abstract

The invention belongs to the field of injection molds, and specifically discloses an ejection mechanism of an injection mold for a housing of an automobile heater; the ejection mechanism comprises a receiving plate arranged between a base and a fixed mold, a plurality of ejector rods are arranged on the receiving plate, and telescopic rods are arranged on the upper ends of the ejector rods; the diameter of the telescopic rods is smaller than the aperture of the through hole, and a sealing plate is arranged on the telescopic rods; three clamping blocks are slidably connected to the side of the cavity of the fixed mold, the clamping blocks are respectively fixedly connected to the piston rods of the corresponding cylinders, and the cylinder bodies of the cylinders are all fixedly connected to the fixed mold; the rodless cavity of the first cylinder is connected to the rod cavities of the second cylinder and the third cylinder respectively through pipelines, and the rodless cavities of the second cylinder and the third cylinder are both provided with ventilation holes; a first rack is fixed on the first clamping block, the first rack is meshed with a gear, the gear is meshed with a second rack, and the second rack is fixedly connected to the receiving plate; the purpose of the invention is to solve the problem that when a worker does not take down the product, the ejection mechanism drives the product to move downward and collide with the cavity, and the product may fall and be damaged.
