[0002] An injection mold is a tool for producing plastic products. It is also a tool that gives plastic products a complete structure and precise dimensions. Injection molding is a processing method used in mass production of certain parts with complex shapes. Specifically, it refers to the high-pressure injection of heated and melted plastic into the mold cavity by an injection molding machine, and after cooling and solidification, a molded product is obtained. In the production process of plastic products, a cooling structure for injection molds used in the production of plastic products is often required.

DETAILED DESCRIPTION

[0023] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0024] Example: Figure 1-5 As shown, the utility model is an injection mold cooling structure for producing plastic products, including a box body 1, a hydraulic cylinder 2 is fixedly installed on the upper end of the box body 1, the lower end of the hydraulic cylinder 2 is bolted to an upper mold 3, a fixing box 4 is fixedly installed on the lower end of the box body 1, a plurality of bases 5 are fixedly connected inside the fixing box 4, a sleeve 6 is fixedly connected to the top of the base 5, a compression spring 7 is fixedly connected inside the sleeve 6, a slide rod 8 is fixedly connected to the upper end of the compression spring 7, a mounting plate 9 is fixedly welded to the top of the slide rod 8, and a bottom plate 10 is fixedly connected to the upper end of the mounting plate 9.

[0025] Among them, the outer periphery of the bottom plate 10 is slidably connected to the lower mold 11, the upper part of the fixed box 4 is symmetrically and detachably connected to the support plate 12, and a handle 13 is fixedly welded to one side of the support plate 12. By setting the support plate 12, after the support plate 12 is removed, the bottom plate 10 can be lifted up by pressing the lower mold 11, so that it can be demolded faster, thereby solving the problem of difficult demolding of existing injection molds during use.

[0026] Among them, a cooling box 14 is fixedly installed on the outer side of the lower mold 11, and a cooling water pipe 15 is fixedly connected to the inside of the cooling box 14. A telescopic hose 16 is fixedly connected to one side of the cooling box 14, and the telescopic hose 16 is connected to the cooling water pipe 15. By setting the cooling water pipe 15, water is circulated on the snake-shaped cooling water pipe 15 using a water tank 17 and a refrigerator 19 to reduce the temperature of the mold.

[0027] Among them, a water tank 17 is fixedly installed inside the box body 1, and the water tank 17 is fixedly connected to the telescopic hose 16. A return pipe 18 is fixedly connected to one side of the cooling box 14, and the return pipe 18 is connected to the cooling water pipe 15. By setting the return pipe 18, the effect of cold water circulation is achieved, the cooling speed is accelerated without constantly changing the water.

[0028] A refrigerator 19 is fixedly installed on one side of the water tank 17, and a water inlet 20 is fixedly connected to one side of the water tank 17 through the box body 1. By setting the refrigerator 19, the water temperature is reduced to achieve rapid cooling.

[0029] Among them, a heat absorbing plate 21 is arranged on one side close to the cooling box 14, a heat sink 22 is fixedly connected to one side of the heat absorbing plate 21, and the heat sink 22 is embedded and connected with the box body 1. By setting the heat sink 22 and cooperating with the heat absorbing plate 21, the internal heat is absorbed, and then the heat is dissipated through the heat sink 22. The heat dissipation fan 23 speeds up the heat dissipation speed, thereby accelerating the cooling.

[0030] Among them, a cooling fan 23 is fixedly installed on the surface of the box body 1, a cooling port 24 is opened on the bottom of the box body 1, a door panel 25 is rotatably connected to one side of the box body 1 through a hinge, and an observation window 26 is embedded inside the door panel 25. By setting the cooling port 24, the cooling fan 23 draws fresh air from the outside and discharges the heat in the mold through the cooling port 24, thereby cooling the mold.

[0031] Working principle: When the hydraulic cylinder 2 drives the upper mold 3 to separate from the lower mold 11, the cooling fan 23 is started to drive the airflow into the box body 1 to cool the lower mold 11 in all directions. The heat absorbing plate 21 absorbs heat from the box body 1, and then the heat is dissipated through the heat sink 22. The cooling fan 23 accelerates the heat dissipation speed in the box body 1, thereby accelerating the cooling. The hot air is dissipated through the heat dissipation port 24. At the same time, water is injected into the water tank 17 through the water inlet 20, and the refrigerator 19 is started. The water tank 17 and the refrigerator 19 are used to circulate water in the snake-shaped cooling water pipe 15 to reduce the mold. The temperature of the mold is increased due to the relatively large cooling area of ​​the snake shape, which can improve the cooling effect and help accelerate the cooling speed. Through the reflux pipe 18, the water in the cooling water pipe 15 returns to the water tank 17, realizing the role of cold water circulation, accelerating the cooling speed without constantly changing water, and effectively improving the cooling effect of the lower mold 11, facilitating rapid molding, and preventing deformation during demoulding. After cooling, remove the support plate 12, press the lower mold 11, and the compression spring 7 in the sleeve 6 will drive the slide bar 8 to slide in the sleeve 6, and lift the bottom plate 10, and the model in the lower mold 11 will be removed and demoulded.
