Description

Technical Field

[0001] This utility model relates to the field of plastic mold technology, specifically to a plastic mold that can be rapidly cooled. Background Technology

[0002] Plastic molds are a type of combined mold used for compression molding, extrusion molding, injection molding, blow molding, and low-foaming molding. The coordinated changes of the mold's punch, die, and auxiliary molding system allow for the production of a series of plastic parts of different shapes and sizes. Plastic molds are generally used for one-piece molding of plastic products, which significantly shortens production time and imparts better physical properties to the plastic, making the product more stable. Cooling devices are needed to cool the plastic products during processing. Currently, most plastic molds use water cooling to cool the cavity, utilizing the circulation of cooling water. This relatively simple cooling method results in a fixed cooling rate, hindering the rapid molding of injection-molded products. When processing large quantities of plastic products, this leads to a longer production cycle and reduced work efficiency.

[0003] Therefore, this utility model provides a plastic mold that can be cooled quickly. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a plastic mold that can be cooled quickly, so as to solve the problems mentioned in the background art. This utility model can improve heat dissipation efficiency by using a cooling structure to assist in heat dissipation, thereby facilitating the rapid molding of injection molded products, reducing the production cycle, and improving work efficiency.

A water tank is installed on the lower side of the mounting frame, and a water pump is installed inside the water tank. The water pump corresponds to the first and second cooling water pipes. Multiple heat-conducting plates are installed around the lower mold. Cooling structures are installed on both the mounting frame and the periphery of the water tank, and the cooling structures correspond to the heat-conducting plates.

[0006] Furthermore, a first electric cylinder is fixed on the mounting frame, and the output end of the first electric cylinder is fixedly connected to the upper mold.

[0007] Furthermore, the first cooling water pipe is connected to the second cooling water pipe, and the second cooling water pipe is located on the lower side of the lower mold.

[0008] Furthermore, one end of the first cooling water pipe is connected to the water tank, the second cooling water pipe is connected to the outlet of the water pump, and the inlet of the water pump is located at the bottom of the water tank.

[0009] Furthermore, the refrigeration structure includes multiple first refrigeration plates and multiple second refrigeration plates, with the first refrigeration plates fixedly connected to the mounting bracket and the second refrigeration plates fixedly connected to the water tank.

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figures 1 to 4 This utility model provides a technical solution: a rapidly cooling plastic mold, including a mounting frame 1, on which an upper mold 2 and a lower mold 3 are mounted. A first cooling water pipe 5 is installed inside the lower mold 3, and a second cooling water pipe 6 is installed inside the mounting frame 1. A water tank 11 is installed on the lower side of the mounting frame 1, and a water pump 12 is installed inside the water tank 11. The water pump 12 corresponds to the first cooling water pipe 5 and the second cooling water pipe 6. Multiple heat-conducting plates 9 are installed on the periphery of the lower mold 3. Cooling structures are installed on the mounting frame 1 and the periphery of the water tank 11, and the cooling structures correspond to the heat-conducting plates 9.

[0022] In this embodiment, a first electric cylinder 4 is fixed on the mounting bracket 1. The output end of the first electric cylinder 4 is fixedly connected to the upper mold 2. The first cooling water pipe 5 is connected to the second cooling water pipe 6. The second cooling water pipe 6 is located on the lower side of the lower mold 3. One end of the first cooling water pipe 5 is connected to the water tank 11. The second cooling water pipe 6 is connected to the outlet end of the water pump 12. The inlet end of the water pump 12 is located at the bottom of the water tank 11.

[0023] Specifically, the water pump 12 is started, causing the water pump 12 to draw water, which is then sent from the water tank 11 into the first cooling water pipe 5 and the second cooling water pipe 6 for rapid cooling.

[0024] The refrigeration structure includes multiple first refrigeration plates 8 and multiple second refrigeration plates 13. The first refrigeration plates 8 are fixedly connected to the mounting bracket 1, and the second refrigeration plates 13 are fixedly connected to the water tank 11. The refrigeration end of the first refrigeration plate 8 is in contact with the heat-conducting plate 9. Multiple second electric cylinders 7 are fixed on the mounting bracket 1. The output end of the second electric cylinders 7 is fixedly connected to the heat-conducting plate 9. Multiple first heat sinks 10 are fixed on the heating end of the first refrigeration plate 8.

[0025] Specifically, energizing the first cooling chip 8 and the second cooling chip 13 will enable cooling. The first cooling chip 8 can cool the heat-conducting plate 9. When rapid cooling is required, the second electric cylinder 7 is activated, causing the second electric cylinder 7 to push the heat-conducting plate 9 into contact with the lower mold 3, thus enabling auxiliary cooling.

[0026] The water in the water tank 11 can be cooled by the second cooling chip 13, and the cooling fan 15 can be started to accelerate the air flow, thereby increasing the heat dissipation efficiency of the first heat sink 10 and the second heat sink 14.
