Description

Technical Field

[0001] The utility model belongs to the technical field of injection molds, and in particular relates to a high-efficiency cooling device for injection molds of medical devices. Background Art

[0002] Injection molds are tools for producing plastic products, and they are also tools that give plastic products complete structures and precise dimensions. Injection molding is a processing method used in the 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. Based on the processing method of medical device injection molds, it will face a variety of usage situations when it is used, but it is not limited to the one proposed below. More specifically, especially after the injection molded part is formed, the injection mold needs to be cooled so that the injection molded part can be taken out of the injection mold.

The injection mold cooling mechanism can quickly cool the injection mold internally by injecting cooling water into the water inlet, without the need for the staff to wait for natural cooling; and then the fan is used for secondary cooling and removal of the remaining cooling water of the former, which is highly practical.

[0026] A high-efficiency cooling device for injection molds of medical devices, comprising: an operating platform 1, a support frame 4 is fixedly connected to the surface of the operating platform 1, an electric telescopic rod 5 is installed on the surface of the support frame 4, an upper mold 6 is fixedly connected to the output end of the electric telescopic rod 5, a cooling cavity 7 is fixedly connected to the surface of the operating platform 1, a lower mold 8 is fixedly connected to the center of the cooling cavity 7, a cooling groove 17 is provided inside the cooling cavity 7, a cooling pipe 15 is installed inside the cooling groove 17, a supporting leg 2 is fixedly connected to the bottom of the operating platform 1, a fixing plate 3 is fixedly connected to the surface of the supporting leg 2, a circulating water pump 11 is installed on the surface of the fixing plate 3, a drain pipe 12 and a water suction pipe 13 are movably connected to the surface of the circulating water pump 11, a refrigerator 14 is movably connected to the other end of the drain pipe 12, a water storage barrel 10 is movably connected to the other end of the water suction pipe 13, and a water inlet end and a water outlet end of the cooling pipe 15 are movably connected to the refrigerator 14 and the water storage barrel 10 respectively.

[0027] In a specific embodiment of the utility model, the circulating water pump 11 and the refrigerator 14 are used in conjunction to enable the device to circulate water resources when cooling the injection mold, thereby avoiding the problem of water waste caused by the current solution not designing circulating water. The cooling chamber 7 and the cooling pipe 15 are used in conjunction to allow the device to take away the heat of the mold without passing through the mold during cooling, thereby avoiding the problem of steam explosion, thereby improving the environmental protection and safety of the high-efficiency cooling equipment for medical device injection molds.

[0028] Specifically, there are four supporting legs 2 , which are respectively located at the four corners of the bottom of the operating platform 1 .

[0029] In a specific embodiment of the utility model, the arrangement of the support legs 2 makes the device more stable and avoids shaking, thereby improving the stability of the efficient cooling device for the injection mold of medical devices.

[0030] Specifically, a placement groove 16 is opened on the surface of the cooling cavity 7 , and the length and width of the placement groove 16 are the same as the length and width of the lower mold 8 .

[0031] In a specific embodiment of the utility model, the arrangement of the placement groove 16 enables a close connection between the cooling cavity 7 and the lower mold 8, thereby improving the precision of the high-efficiency cooling device for the injection mold of the medical device.

[0032] Specifically, the cooling cavity 7 and the upper mold 6 have the same length, and ventilation holes 9 are provided at both ends of the opposite surfaces of the cooling cavity 7 and the upper mold 6 .

[0033] In a specific embodiment of the utility model, the provision of the ventilation holes 9 allows cool air to be transmitted through the ventilation holes 9, thereby increasing the cooling speed, thereby improving the efficiency of the high-efficiency cooling device for the medical device injection mold.

[0034] Specifically, opposite sides of the upper mold 6 and the lower mold 8 are both configured as cavity structures, and the cavity structures are used in conjunction with the cooling cavity 7 .

[0035] In a specific embodiment of the utility model, by setting the opposite sides of the upper mold 6 and the lower mold 8 as a cavity structure, the cold energy can be directly in contact with the upper mold 6 and the lower mold 8, thereby expanding the contact area and improving the efficiency of the high-efficiency cooling equipment for the medical device injection mold.

[0038] Working principle: When in use, the electric telescopic rod 5 starts to drive the upper mold 6 downward to press the lower mold 8. At this time, the circulating water pump 11 is turned on to take the water in the water storage bucket 10 out through the water suction pipe 13 and flow to the refrigerator 14 through the drain pipe 12. The water is cooled by the refrigerator 14 and then flows to the inside of the cooling pipe 15 through the water pipe. After the ice water flows to the cooling pipe 15, the injection molded part between the upper mold 6 and the lower mold 8 is cooled. At the same time, the cool air flows between the upper mold 6 and the lower mold 8 through the air permeable through hole 9, adding The other end of the cooling tube 15 is connected to the water storage barrel 10, so that the water in the cooling tube 15 can continuously flow into the water storage barrel 10, and continuously draw water from the water storage barrel 10 and then cool it through the refrigerator 14 and finally flow into the cooling tube 15, so that a water cycle is formed, so that there is a constant supply of cold water in the cooling tube 15 for cooling. However, the coordinated use of the cooling chamber 7 and the cooling tube 15 allows the device to take away the heat of the mold without passing through the mold during cooling, thereby avoiding steam explosion.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
