[0002] Injection molding machines are the main molding equipment that uses plastic molds to make plastic products of various shapes from thermoplastic or thermosetting plastics. Taking injection molding machines with fixed top molds and hydraulic devices as an example, their bottom molds generally adopt anchoring and limiting methods to ensure the accuracy of the connection between the upper and lower molds.

[0003] Some injection molding machines are not convenient for clamping and replacing the injection mold, and it is inconvenient to clean and maintain the injection mold regularly. In addition, the main body of the device is not convenient for auxiliary cooling of the injection mold. Therefore, a quick mold changing device for injection molding machines is proposed to address the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a quick mold changing device for injection molding machines, which solves the problems of some injection molding machines not being able to easily clamp and replace the injection bottom mold, not being able to regularly clean and maintain the injection bottom mold, and not being able to provide auxiliary cooling for the injection bottom mold.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A quick mold change device for an injection molding machine includes an auxiliary mounting structure and a cooling support structure. The cooling support structure is provided on the inner side of the upper part of the auxiliary mounting structure. The auxiliary mounting structure includes a plate, a guardrail, a sleeve, an insert plate, a column rod, and a spring. Two guardrails are symmetrically and fixedly arranged at the top of the plate. A sleeve is fixedly arranged at the front end of the rear guardrail. An insert plate is arranged at the front end of the sleeve. A column rod is fixedly arranged at the rear end of the insert plate. A spring is fixedly arranged between the insert plate and the rear guardrail. The cooling support structure includes a combined plate, an insert strip, an alloy heat-conducting plate, and a copper tube. The bottom of the insert strip is fixedly arranged with the combined plate. Alloy heat-conducting plates are symmetrically and fixedly arranged at the front and rear ends of the partition plate in the middle of the combined plate. A copper tube is fixedly arranged inside the alloy heat-conducting plate.

[0007] Preferably, the springs are spirally distributed on the outside of the sleeve and the outside of the rod, and the rod is slidably disposed with respect to the inner wall of the sleeve.

[0008] Preferably, the copper tube is bent and guided inside the alloy heat-conducting plate, and the bottom of the combined plate is fixedly installed with the plate body.

[0009] Preferably, when the cooling support structure is assembled with the injection mold, the top of the combined plate is in contact with the slot opened at the bottom of the injection mold, the insert is in contact with the slot opened at the bottom of the injection mold, and the top of the alloy heat-conducting plate is in contact with the bottom of the injection mold.

[0010] Preferably, when the auxiliary installation structure provides auxiliary positioning to the injection molding bottom mold, the insert plate engages with the slot opened at the rear end of the injection molding bottom mold.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] In this invention, the insert plate is manually pressed towards the rear end, causing the insert plate to move the column rod towards the rear end.
