Description

Technical Field

[0001] The utility model belongs to the technical field of injection molding, and particularly relates to a rapid cooling device for plastic product processing. Background Art

[0002] In the production process of plastic products, injection molds are used. An injection mold is a tool for producing plastic products, which can mold plastic products into the required product shape and structure. Since the injection mold remains at a high temperature during the production process, it needs to be cooled down.

[0003] Currently, the cooling method used in injection molding is usually heat exchange and heat dissipation through water. One is to cool by spraying water. Cold water is sprayed onto the surface of the mold through a nozzle. However, the contact time between the cooling spray and the mold is extremely short, resulting in poor cooling effect. The other is immersion cooling. The mold is placed in a water tank filled with cold water. However, when the mold is injection molded for a long time, the water temperature in the water tank will rise, making it impossible for the subsequent mold to cool down quickly. Summary of the Utility Model

[0004] The utility model provides a rapid cooling device for plastic product processing, aiming to solve the problem of poor heat dissipation effect of the current injection mold.

[0005] The utility model is realized as follows. A rapid cooling device for plastic product processing includes a cooling tank; a mold is installed at the center of the cooling tank. Fixed pipes are installed on both the left and right sides of the cooling tank. Both ends of the fixed pipes communicate the inside and outside of the cooling tank. A connecting pipe is installed on the outer side of the fixed pipe. A driving pump is installed at the rear side of the cooling tank. Connecting pipes are installed at both the water inlet and outlet of the driving pump. The other end of the connecting pipe at the water outlet of the driving pump is connected to a heat dissipation tank. The heat dissipation tank is installed at the rear side of the cooling tank. The heat dissipation tank is open and a fan is installed at the top. Connecting pipes are installed at both ends of the heat dissipation tank. The other end of the connecting pipe at the water outlet of the heat dissipation tank is connected to the right side of the cooling tank. The cooling tank, the connecting pipes, the driving pump, and the heat dissipation tank form a closed circulation water path.

[0006] Preferably, a partition is installed on the inner side wall of the cooling tank, and drainage holes are opened on both the front and rear sides of the partition.

[0007] Preferably, the partition is located on the left side of the mold and is in contact with its surface, and the surface of the partition is in contact with the inner wall of the cooling tank.

[0008] Preferably, a limiting block is installed on the inner side wall of the cooling tank, and a cover plate is placed above the limiting block. The inner and outer sides of the cover plate are in contact with the outer wall of the mold and the inner wall of the cooling tank respectively.

[0009] Preferably, a positioning plate is installed at the bottom of the mold, and a positioning groove adapted to the positioning plate is provided at the bottom end of the inner wall of the cooling groove.

[0010] Preferably, strip-shaped grooves are evenly formed in the outer side wall of the mold.

[0011] Compared with the prior art, the embodiments of the present application mainly have the following beneficial effects:

[0012] When the mold is used for injection molding, cold water in the cooling groove exchanges heat with the mold, so that the mold can be quickly cooled and the plastic can be quickly cooled. The driving pump inputs the water in the cooling groove into the heat dissipation groove through the connecting pipe. The fan at the top of the heat dissipation groove starts to blow air on the heated water, so that it can be cooled. The cooled water flows back into the cooling groove through the driving pump again. In this way, while realizing the water circulation, the water temperature is also prevented from rising and affecting the normal cooling of the mold. The partition plate separates the water inlet of the cooling groove, so as to prevent the water on one side of the mold from not flowing and circulating completely and affecting its heat dissipation effect.

The other end of the connecting pipe 4 at the outlet of the driving pump 5 is connected to a heat dissipation tank 6. The heat dissipation tank 6 is installed at the rear side of the cooling tank 1. The heat dissipation tank 6 is open and a fan 7 is installed at the top. Connecting pipes 4 are installed at both ends of the heat dissipation tank 6. The other end of the connecting pipe 4 at the outlet of the heat dissipation tank 6 is connected to the right side of the cooling tank 1. The cooling tank 1, the connecting pipe 4, the driving pump 5, and the heat dissipation tank 6 form a closed circulation water path. When the mold 2 is injection-molded, heat exchange occurs between the cold water in the cooling tank 1 and the mold 2, so that the mold 2 can be quickly cooled and the plastic can be quickly cooled. When the cold water in the cooling tank 1 rises in temperature due to heat absorption, the driving pump 5 can be started. The driving pump 5 inputs the water in the cooling tank 1 into the heat dissipation tank 6 through the connecting pipe 4. The fan 7 at the top of the heat dissipation tank 6 starts to blow air on the heated water, so that it can be cooled. The cooled water flows back into the cooling tank 1 through the driving pump 5 again, so as to avoid the water temperature rising and affecting the normal cooling of the mold 2 while realizing the water circulation.

The surface of the partition plate 8 is in contact with the inner wall of the cooling tank 1. The partition plate 8 separates the water inlet of the cooling tank 1, so as to avoid the water on one side of the mold 2 not flowing and circulating completely and affecting its heat dissipation effect.

[0022] Limit blocks 10 are installed on the inner side wall of the cooling tank 1. A cover plate 11 is placed above the limit blocks 10. The inner and outer sides of the cover plate 11 are in contact with the outer wall of the mold 2 and the inner wall of the cooling tank 1 respectively. By providing the cover plate 11, the cover plate 11 can prevent the flowing water from splashing into the inside of the mold 2 and affecting the molding effect of the plastic.

[0023] A positioning plate 12 is installed at the bottom of the mold 2, and a positioning groove adapted to the positioning plate 12 is provided at the bottom end of the inner wall of the cooling tank 1.
