A quick mold change mechanism for injection molding

Abstract

The invention relates to the field of injection molding processing, in particular to a quick mold change mechanism for injection molding processing, which includes an injection molding machine, a positive mold base and a negative mold base installed on the injection molding machine, and also includes a positive mold, a negative mold, a jaw moving mechanism, Elastic clamping mechanism, mechanical grippers, preheating mechanism, placement frame and four demoulding mechanisms, the rapid mold change mechanism for injection molding, preheats the mold on the placement frame through the preheating mechanism, avoiding workers Handling reduces the possibility of workers being in danger, avoids double clamping and installation of the front and back molds, speeds up the process of mold replacement, and reduces the probability of deviation in mold installation due to the removal of the positive mold from the negative mold , the positive mold and the negative mold are tightly connected, only one clamping and disassembly is required, the process of mold replacement is accelerated, and workers are not required to assemble the positive mold and the negative mold together, and the positive mold and the negative mold are assembled together , reducing the footprint of the mold.

Description

technical field [0001] The invention relates to the field of injection molding processing, in particular to 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 patent application num...

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
