[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Refer to Figure 1 - Figure 2, an embodiment provided by the present utility model: an efficient cooling device for pipe processing, including a bottom plate 1 and a moving mold 2. The bottom plate 1 plays a supporting role for the device. At the center of the upper surface of the bottom plate 1, a lower mold 101 is fixedly connected. By matching the moving mold 2 with the lower mold 101, a closed space is formed inside the pipe mold, enabling good closed molding of the injection liquid in the mold, improving the molding effect of the pipe mold. At the center of the upper surface of the moving mold 2, a fixed block 4 is fixedly connected. The fixed block 4 is connected to an external stamping component, enhancing the sealing between the moving mold 2 and the lower mold 101. On the lower side of the front surface of the bottom plate 1, a cooling component 3 is provided. By starting the cooling component 3, the pipe in the bottom plate 1 is cooled, reducing the molding time of the pipe in the mold and improving the molding effect during the processing of the pipe.

[0025] Refer to Figure 2 - Figure 3 , the cooling component 3 includes a water cooling box 31. The water cooling box 31 is fixedly connected to the lower side of the front surface of the bottom plate 1. The output end of the water cooling box 31 is fixedly connected to a water outlet 32. The output end of the water outlet 32 is connected to a heat dissipation block 33 through a pipeline. The heat dissipation block 33 penetrates and is connected to the front surface of the bottom plate 1. On the lower side of the front surface of the bottom plate 1, near the right side of the heat dissipation block 33, a mounting seat 34 is fixedly connected. The output end of the mounting seat 34 is fixedly connected to a cooling pipe 35. By starting the water cooling box 31, a water cooling circulation path is formed through the water inlet 39 in cooperation with the cooling pipe 35 and the water outlet 32. The heat dissipation fins 38 are arranged in a T-shaped structure, enabling the part of the heat dissipation fins 38 extending out of the bottom plate 1 to be cooled more quickly by the water cooling circulation. The water cooling effect is combined with the external ventilation effect to improve the heat dissipation rate of the lower mold 101 in the bottom plate 1. The cooling component 3 in the bottom plate 1 constitutes a multi-channel type cooling, enhancing the rapid cooling and shaping effect of the mold. At the center of the bottom of the inner wall of the bottom plate 1, multiple heat absorption columns 36 are arranged. The heat absorption columns 36 are connected through a heat conduction pipe 37. The upper surface of the inner wall of the bottom plate 1 is detachably connected with a heat conduction plate 311. Through the heat conduction plate 311, the heat of the moving mold 2 and the lower mold 101 is introduced into the bottom plate 1. The heat of the heat conduction plate 311 is absorbed by the heat absorption columns 36. The heat absorption columns 36 cooperate with the heat conduction pipe 37 to transfer the heat to the heat dissipation fins 38. The heat conduction pipe 37 is fixedly connected to the inner wall aperture of the heat absorption column 36. Multiple evenly distributed small through holes are formed on the upper surface of the heat conduction plate 311. The cross-sectional area of the heat absorption column 36 is adapted to the cross-sectional area of the through holes of the heat conduction plate 311. The left end of the heat absorption column 36 is fixedly connected to a heat dissipation fin 38. The input end of the water cooling box 31 is fixedly connected to a water inlet 39. By using the gap in the bottom plate 1 and the bottom circular groove, the hot air accumulated in the bottom plate 1 is led out to the outside for heat exchange, improving the uniform heat conduction effect of the bottom plate 1 on the mold, enhancing the shaping effect in the injection mold, and improving the cooling effect of the cooling component 3 on the pipe mold.

[0026] Refer to Figure 1 and Figure 4, on the left side of the upper surface of the moving mold 2, there are multiple groups of auxiliary components 5. The auxiliary component 5 includes an auxiliary block 51. The outer wall of the auxiliary block 51 is fixedly connected to the inner wall on the left side of the upper surface of the moving mold 2. On the upper surface of the auxiliary block 51, there is a positioning cylinder 52 fixedly connected. At the left end of the inner wall of the auxiliary block 51, there is a chute 54. A sliding plate 53 is slidably connected to the inner wall of the chute 54. The ejector rod in the external machine body is inserted into the auxiliary block 51 through the positioning cylinder 52, squeezing the sliding plate 53, causing the sliding plate 53 to move downward under the action of the chute 54. The sliding plate 53 is fixedly connected to a through column 56. A spring 55 is sleeved on the outer wall of the through column 56. The top end of the spring 55 is fixedly connected to the lower surface of the sliding plate 53, and the bottom end of the spring 55 is fixedly connected to the upper surface of the fixing plate 57. During the process of the spring 55 playing a damping role on the ejector rod, it avoids the situation of excessive die pressing of the ejector rod during the injection molding process. At the left end of the inner wall of the auxiliary block 51, there is a fixing plate 57 fixedly connected. The lower surface of the auxiliary block 51 is fixedly connected to a protective shell 58. The inside of the protective shell 58 is a hollow structure. The outer wall of the through column 56 runs through and is connected to the center of the lower surface of the auxiliary block 51. The downward movement of the sliding plate 53 causes the through column 56 to move downward, and the through column 56 protrudes out of the protective shell 58, exerting a squeezing effect on the upper surface of the bottom plate 1, achieving the separation of the bottom plate 1 and the moving mold 2, making the die pressing forming plane more flat when the moving mold 2 is separated from the lower mold 101, and improving the demolding effect of the material pipe mold.

[0027] Working principle: Start the device. By mating the moving mold 2 with the lower mold 101, a closed space is formed inside the material pipe mold. Start the water cooling box 31. Through the water inlet 39, the cooling pipe 35 and the water outlet 32 cooperate to form a water cooling circulation path. The heat dissipation fins 38 are set in a T-shaped structure, so that the part of the heat dissipation fins 38 extending out of the bottom plate 1 is cooled more rapidly by the water cooling circulation effect. The water cooling effect is combined with the external ventilation effect. The cooling assembly 3 in the bottom plate 1 constitutes a multi-channel type cooling, enhancing the rapid cooling and shaping effect of the mold. The heat of the moving mold 2 and the lower mold 101 is introduced into the bottom plate 1 through the heat conduction plate 311. The heat absorption column 36 absorbs the heat of the heat conduction plate 311. The heat absorption column 36 cooperates with the heat conduction pipe 37 to transfer the heat to the heat dissipation fins 38. The gaps in the bottom plate 1 and the bottom circular grooves are used to guide the hot air accumulated in the bottom plate 1 to the outside, and heat exchange is carried out to improve the uniform heat conduction effect of the bottom plate 1 on the mold, enhancing the shaping effect in the injection mold. When the material pipe mold needs to be demolded, start the auxiliary assembly 5. Through the positioning cylinder 52, the ejector rod in the external machine body extends into the auxiliary block 51, squeezing the slide plate 53, so that the slide plate 53 moves downward under the action of the chute 54. During the process of the spring 55 playing a damping role on the ejector rod, it avoids the situation of excessive die pressing of the ejector rod during the injection process. During the process of the spring 55 playing a damping role on the ejector rod, it avoids the situation of excessive die pressing of the ejector rod during the injection process. The downward movement of the slide plate 53 makes the through column 56 move downward, and the through column 56 extends out of the ejection protective shell 58, exerting an extrusion effect on the upper surface of the bottom plate 1, achieving the separation of the bottom plate 1 and the moving mold 2, making the die pressing forming plane more flat when the moving mold 2 and the lower mold 101 are separated, and improving the demolding effect of the material pipe mold.
