A working method of a quick mold change mechanism for injection molding

Abstract

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, comprising an injection molding machine, a positive mold base and a negative mold base installed on the injection molding machine, and a positive mold, a negative mold, and grippers Moving mechanism, elastic inserting mechanism, mechanical gripper, preheating mechanism, placing frame and four demoulding mechanisms, the rapid mold change mechanism for injection molding process preheats the mold on the placing frame through the preheating mechanism, avoiding the Workers carry the mold, which 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 occurrence of mold installation by removing the positive mold from the negative mold. The probability of deviation, the tight connection between the positive mold and the negative mold, only needs to be clamped and disassembled once, which speeds up the process of mold replacement, and does not require workers to assemble the positive mold and the negative mold together. Packed together, the footprint 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
