Description

A high-pressure cooling structure for a miniature mold insert Technical Field

[0001] This utility model relates to the field of cooling technology for mold inserts, and specifically to a high-pressure cooling structure for micro-sized mold inserts. Background Technology

[0002] When casting barrel-shaped parts with complex sides, such as automotive wheel hubs, the casting molds typically include upper and lower molds, as well as side molds located around the upper and lower molds. Cooling points for the side molds are located at the junction of the wheel spokes and the rim. The conventional cooling method is air cooling, which is mainly achieved by machining blind holes in the corresponding positions of the side mold's back cavity and then installing air ducts. With increasingly demanding requirements from die-cast automotive parts customers, the forming and auxiliary processes for die-cast automotive parts are also developing simultaneously, giving rise to auxiliary processes such as vacuum die casting, high-pressure spot cooling, mold temperature controllers, and water temperature controllers. High-pressure spot cooling, as an important aspect, has also evolved into many forms, all aimed at improving product yield and production efficiency.

[0003] The specification of a side mold cooling insert structure for cooling wheel hub molds (publication number CN206567521U) mentions that it "includes an upper mold, a lower mold, and a side mold. The side mold has a stepped through hole at the junction of the wheel spoke and the rim. A cooling insert is provided in the stepped through hole. A stepped blind hole is opened on the end face of the cooling insert. An inlet tube is inserted into the stepped blind hole. An outlet hole is opened on the side of the cooling insert. An outlet tube is inserted into the outlet hole." However, the space of the micro-sized inserts in the prior art is limited. Conventional cooling channels are difficult to process and are prone to insufficient structural strength. Moreover, the high-pressure sealing is poor, which can easily lead to leakage, resulting in mold contamination or reduced cooling efficiency. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, a high-pressure cooling structure for micro-sized mold inserts is provided to solve the problems of limited space for micro-sized inserts, difficulty in processing conventional cooling channels leading to insufficient structural strength, poor high-pressure sealing, easy leakage leading to mold contamination or reduced cooling efficiency in existing technologies.

[0005] To achieve the above objectives, a high-pressure cooling structure for a micro-sized mold insert is provided, comprising an insert body, a slider seat mounted at the rear end of the insert body, and a heat-conducting layer covering the outer surface of the insert body. A cooling water pipe is mounted in the upper part of the insert body, and the rear part of the cooling water pipe extends into the upper front part of the slider seat. A second upper connecting water pipe and a third lower connecting water pipe are respectively mounted on the upper and lower sides of the rear part of the slider seat, and a low-pressure outlet is provided at the rear end of both the second upper connecting water pipe and the third lower connecting water pipe, and an adjustable diverter valve is connected to the rear of the low-pressure outlet.

[0006] Furthermore, the molded part of the insert body is protruding, and the size of the protrusion at the front end of the insert body is set to 10mm×10mm.

[0007] Furthermore, the thermally conductive layer covering the outer surface of the insert body adopts a nano-ceramic thermally conductive layer structure, and the outer surface of the insert body is smoothly disposed.

[0008] Furthermore, a sealing ring is fitted at the rear of the cooling water pipe, and the sealing ring adopts an O-ring structure, and the sealing ring is located at the connection gap between the insert body and the slider seat.

[0009] Furthermore, the rear end of the cooling water pipe is connected to a first upper connecting water pipe, and the left side of the first upper connecting water pipe is connected to a second upper connecting water pipe.

[0010] Furthermore, a middle water delivery pipe is connected to the lower rear side of the cooling water pipe, and a first lower connecting water pipe is connected to the middle of the middle water delivery pipe. A second lower connecting water pipe is connected to the left end of the first lower connecting water pipe, and a third lower connecting water pipe is connected to the upper rear side of the second lower connecting water pipe.

[0011] Furthermore, a front guide tube is provided at the front of the cooling water pipe, a rear sleeve plate is fitted on the rear side of the cooling water pipe, and a rear guide tube is provided at the rear of the cooling water pipe. Both the front guide tube and the rear guide tube are connected to the cooling water pipe.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. In this utility model, the water pipe is deeply embedded in the molding part and combined with a high thermal conductivity coating to improve heat exchange efficiency. The internal flow channel is polished to improve cooling efficiency.

[0014] 2. In this utility model, the cooling water pipe and the slider seat are connected by a tapered thread, which ensures that the two water circuits are completely separated and there is no leakage. It is more tightly leak-proof, adaptable to miniature inserts, and the tapered seal is pressure resistant. Moreover, the modular joint and diversion valve support quick disassembly and assembly, reducing downtime.

[0015] 3. The low-pressure outlet connected to the adjustable diverter valve at the rear end of the second upper connecting water pipe and the third lower connecting water pipe in this utility model is used to dynamically adjust the outlet flow rate. It has a compact and reliable structure.

[0016] 4. In this utility model, the insert body and the slider seat adopt a double cooling water pipe structure. The water pipes penetrate deep into the molding part to ensure that the two water paths are completely separated and there is no water leakage, so as to achieve efficient cooling and long-term stable operation.
