Working method of quick mold changing mechanism for injection molding

Abstract

The invention relates to the field of injection molding, in particular to a working method of a quick mold changing mechanism for injection molding. The mechanism comprises an injection molding machine, a positive mold base and a negative mold base, the positive mold base and the negative mold base are arranged on the injection molding machine, and the mechanism further comprises a positive mold,a negative mold, a clamping jaw moving mechanism, an elastic inserting mechanism, a mechanical clamping jaw, a preheating mechanism, a placing frame and four demoulding mechanisms. According to the quick mold changing mechanism for the injection molding, a mold on the placing frame is preheated by the preheating mechanism, workers are prevented from carrying the mold, the possibility that the workers are dangerous is reduced, two times of clamping and mounting the positive mold and the negative mold are avoided, the process of replacing the molds is accelerated, the probability of deviation ofthe mounting of the mold is reduced due to the fact that the positive mold is taken down from the negative mold, the positive mold and the negative mold are tightly connected, only one time of clamping and dismounting is needed, the process of replacing the mold is accelerated, the workers are not needed to assemble the positive mold and the negative mold together, the positive mold and the negative mold are assembled together, and the occupied area of the mold is reduced.

Description

technical field [0001] The invention relates to the field of injection molding processing, in particular to a working method of a quick mold change mechanism for injection molding processing. Background technique [0002] Injection molding machine is also known as injection molding machine or injection machine. It is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products with plastic molding molds. When replacing the mold on the injection molding machine, the mold is first lifted out of the injection molding machine by a crane, and then passed The crane lifts the new mold into the injection molding machine, and then completes the replacement of the mold. When installing the mold for a small injection molding machine, the worker often moves the mold into the injection molding machine, and then replaces the mold on the injection molding machine. And the handling process is too dangerous. [0003] my country's pa...

AI Technical Summary

Problems solved by technology

[0005] 1. Although this solution can quickly clamp the mold and realize quick mold change, this equipment needs to clamp and disassemble the front and back molds twice, and when installing the mold, it also needs to carry out two times of front and back molds Clamping installation, mold change process is too slow

[0006] 2. The installation accuracy of the mold is too high, and the installation deviation of the front and back molds often occurs when the mold is installed separately.

[0007] 3. When the mold is clamped and replaced, the positive and negative molds are often clamped to two places, and the positive and negative molds cannot be assembled together. Workers are required to assemble them together, which wastes a lot of working time for workers.

[0008] 4. When the mold is installed, the mold of this scheme is in a cold state. After the mold is installed, it is necessary to heat the front and back molds, which wastes a lot of working time for workers
