Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold rapid cooling structure. Background Technology

[0002] Injection molds are core equipment in the mass production of plastic products. Their working principle involves injecting molten plastic raw material into the mold cavity under high pressure. After cooling and solidification, a plastic product perfectly conforming to the shape of the cavity is obtained. This technology is widely used in almost all plastic product fields, including automobiles, home appliances, electronic communications, medical equipment, and daily consumer goods. Its core advantage lies in its ability to achieve rapid one-step molding of complex products, ensuring extremely high dimensional consistency and production efficiency, making it an indispensable key technology in modern manufacturing.

[0003] The time required for raw materials to solidify from a molten state in the mold cavity is called cooling time, which typically accounts for more than 70% of the entire injection molding cycle. Cooling transforms the raw material from a viscous flow state to a solid state, thereby obtaining the desired shape and sufficient strength so that it can be ejected intact without damage when the mold is opened. In existing technologies, to improve cooling efficiency and reduce cooling time, cavities or channels are set inside or below the lower mold and coolant is introduced. However, after prolonged use, scale, rust, and algae will accumulate in the cavities or channels, hindering heat conduction and making them difficult to clean. In addition, due to the interconnected channels and large cavity area, the coolant will become increasingly hot, resulting in poor cooling effect at the rear mold. In summary, there is room for technological improvement. Utility Model Content

[0004] This invention aims to solve the aforementioned technical problems, namely, the poor cooling effect of the rear mold due to the interconnected water channels, large cavity area, difficulty in cleaning, and the increasing heat of the coolant during conduction. It provides a rapid cooling structure for the mold.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a mold rapid cooling structure, including a number of pipes that can be connected end to end, wherein an inlet pipe and an outlet pipe are respectively connected near both ends of the pipes, and each inlet pipe is equipped with a valve;

[0006] A coolant circulation structure is provided on the pipeline and near the outlet pipe; the coolant circulation structure includes a first hose and a second hose connected to the pipeline, and a U-shaped circulation pipe is provided between the first hose and the second hose; a fixing plate is provided on the outside of the circulation pipe and near the upper end; a pump is connected to the circulation pipe.

[0007] Furthermore, the ends of the inlet pipe and the outlet pipe are connected to a liquid distribution box, which is connected to an external coolant storage device; the liquid distribution box can be provided with multiple outlets and is threadedly connected with a cover plate.

[0008] Furthermore, both ends of the pipe are provided with connecting flanges, and the connecting flanges are detachably connected by bolts.

[0009] Furthermore, it also includes a base for mounting the lower mold; the base is provided with several circular grooves that can accommodate the circulation pipe.

[0010] Furthermore, the fixing plate is mounted on one of the circular grooves, and the bottom surface of the fixing plate is provided with a sealing ring that can extend into the circular groove.

[0011] Furthermore, the circulation pipe is provided with a hollow cylinder, and the front of the hollow cylinder is provided with a viewing window.

[0012] The advantages of this utility model compared with the prior art are as follows:

[0013] By connecting multiple pipes to the independently connected inlet pipe, outlet pipe, hose one, hose two, and circulation pipe, multiple cooling structures can be connected in parallel, allowing simultaneous cooling of multiple locations on the base. This avoids uneven cooling caused by excessively long liquid paths and prevents subsequent warping. Attached Figure Description

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Example 1, in conjunction with Appendix Figure 1 , 3A rapid cooling structure for a mold includes several pipes 1 that can be connected end to end. Each pipe 1 has a connecting flange 5 at both ends, and the connecting flanges 5 are detachably connected by bolts. The number of connected pipes 1 can be adjusted at will according to the actual area and location to be cooled, so that they can be placed stably on the base 10 (described below) for easy use.

[0021] Combined with appendix Figure 1 , 3 Pipe 1 is connected to an inlet pipe 2 and an outlet pipe 3 near both ends, and each inlet pipe 2 is equipped with a valve 4; the inlet pipe 2 and the outlet pipe 3 enable the circulation of liquid in pipe 1, which facilitates the entry of low-temperature coolant and the discharge of the heated coolant.

[0022] Combined with appendix Figure 1 , 3 4. A coolant circulation structure is provided on pipe 1 and near the outlet pipe 3. Specifically, the coolant circulation structure includes a first hose 6 and a second hose 7 connected to pipe 1, and a U-shaped circulation pipe 8 is provided between the first hose 6 and the second hose 7. Thus, the first hose 6, the second hose 7 and the circulation pipe 8 form another circulation on pipe 1. The circulation pipe 8 is a rigid pipe that is inserted into the circular groove 11 mentioned below to achieve cooling of the corresponding area. In addition, a pump is connected to the circulation pipe 8 to provide the power for circulation.

[0023] Combined with appendix Figure 2 It also includes a base 10, which is used to house the lower mold. In actual use, the base 10 has a groove that can accommodate the lower mold. Based on the above, the base 10 has several circular grooves 11 that can accommodate the circulation pipe 8. Thus, according to the position and size of the lower mold, the circulation pipe 8 is inserted into several circular grooves 11 around it to achieve accurate cooling and reduce unnecessary energy consumption. A fixing plate 9 is provided on the outside of the circulation pipe 8 and near the upper end. The fixing plate 9 is mounted on one of the circular grooves 11 to support the circulation pipe 8. In addition, the circulation pipe 8 is in close contact with the inner side of the circular groove 11 to improve the heat conduction effect. The bottom surface of the fixing plate 9 is provided with a sealing ring 12 that can extend into the circular groove 11 to seal the upper end of the circular groove 11 and improve the heat conduction effect.

[0024] Combined with appendix Figure 4 A hollow cylinder 13 is provided on the circulation pipe 8. A viewing window is provided on the front of the hollow cylinder 13. The corresponding circulation pipe 8 can be observed through the viewing window of the hollow cylinder 13 to avoid the inability to perform cooling operations when the pump is damaged.

[0025] Example 2, in conjunction with Appendix Figure 1The ends of the inlet pipe 2 and the outlet pipe 3 are connected to a liquid distribution box. The liquid distribution box is a simple sealed box used for liquid distribution, which is not shown in the figure. The liquid distribution box is connected to an external coolant storage device for liquid distribution. The liquid distribution box can be provided with multiple liquid outlets and is threaded with a cover plate. The liquid outlets not connected to the inlet pipe 2 and the outlet pipe 3 can be sealed by the cover plate.
