Automatic jacking device of injection mold

Abstract

The invention relates to the technical field of injection molds, and discloses an automatic jacking device of an injection mold. The automatic jacking device of the injection mold comprises a top board, wherein supporting columns are fixedly installed at both sides of the top board, fixing boards are fixedly installed at both sides, close to each other, of the two supporting columns, a same lowerhalf is fixedly installed at the sides, close to each other, of the two fixing boards, a lower half cavity is formed in the top of the lower half, a sliding groove is formed in an inner wall of the bottom of the lower half cavity, a sealing groove is formed in the bottom of the lower half, the sealing groove communicates with the sliding groove, two sliding boards are slidingly installed in the sealing groove, and rotating boards which are obliquely arranged are rotatably installed on both the sliding boards. The automatic jacking device of the injection mold is simple in structure and convenient to operate, by moving an upper half upwards and downwards, the lower half cavity and an upper half cavity are closed and opened conveniently, through movement of jacking boards, injection moldingparts are jacked, a yield of the injection molding parts is increased, use is convenient and ingenious, the automatic jacking device of the injection mold is suitable for wide popularization, and useeffects are met.

Description

technical field [0001] The invention relates to the technical field of injection molds, in particular to an automatic ejection device for injection molds. Background technique [0002] The ejector device is a device that cooperates with the mold in the opening and closing part of the injection molding machine to realize the function of ejecting and dropping plastic products. Commonly used ejection devices are mostly equipped with independent driving power, such as hydraulic pressure or air pressure. Although the hydraulic ejection device is convenient to adjust the speed, position and stroke, the result is complicated and the force is small. [0003] Although the method of using compressed air to blow out plastic products will not leave marks on the plastic products, it is necessary to install air passages and air holes on the mold, and it is necessary to add an air source, and the ejection efficiency is low, which is inconvenient to align the upper mold. Carry out mold cl...

AI Technical Summary

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides an automatic ejector device for injection molds, which is equipped with the ability to move the upper mold up and down to facilitate mold closing and opening of the lower mold cavity and the upper mold cavity, and through the movement of the ejector plate Ejection of injection molded parts improves the yield of injection molded parts. It is convenient and ingenious to use, suitable for widespread promotion, and satisfies the advantages of use. It solves the problem of using compressed air to blow out plastic products. Although it will not be used in plastic products However, it is necessary to set air passages and air holes on the mold, and it is necessary to add an air source, and the ejection efficiency is low, and it is inconvenient to close and open the upper mold and the lower mold, so it cannot meet the needs of users The problem
