Description

Technical Field

[0001] This utility model relates to the field of powder metallurgy technology, and in particular to a cooling device for a detachable powder metallurgy mold. Background Technology

[0002] Powder metallurgy is a process technology that uses metal powders (or mixtures of metal and non-metal powders) as raw materials, followed by forming and sintering, to manufacture metallic materials, composite materials, and various types of products. Powder metallurgy shares similarities with ceramic production, both belonging to powder sintering technology; therefore, a range of new powder metallurgy technologies can also be applied to the preparation of ceramic materials. Due to its advantages, powder metallurgy technology has become a key to solving new materials problems and plays a crucial role in the development of new materials.

[0003] The problems with existing technologies are as follows: When using powder metallurgy molds, cooling is required to maintain the temperature of the molds within a certain range to ensure the accuracy of the workpiece dimensions after molding. Existing cooling devices for powder metallurgy molds cannot directly cool the molds and require indirect cooling through contact with external refrigerants. This results in poor uniformity of cooling, low cooling efficiency, and large temperature differences after cooling, leading to thermal stress concentration and shortening the mold's lifespan. Therefore, we propose a detachable cooling device for powder metallurgy molds to solve these problems. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a cooling device for detachable powder metallurgy molds.

[0029] The cooling mechanism includes a spiral copper tube 610, a circulating pump 620, and a suction pipe 621. A conveying pipe 630 is fixed to one side of the circulating pump 620, and a connector A631 is fixed to one end of the conveying pipe 630. The feed end of the spiral copper tube 610 is connected to the connector A631. A mounting buckle 640 is bolted to the side of the mounting base 100 near the circulating pump 620. A storage tank 650 is fixed to the inner wall of the mounting buckle 640, and a return pipe 660 is fixed to the inner wall of the storage tank 650. A connector B661 is fixed to one end of the return pipe 660, and the return end of the spiral copper tube 610 is connected to the connector B661. An installation mechanism is provided to place the metallurgical mold 240 to be used on the mounting base plate 210, align the positioning cover plate 230 with multiple magnetic positioning posts 220 and insert them, and position them magnetically. The column 220 magnetically fixes the positioning cover plate 230, enabling convenient installation and disassembly of the metallurgical mold 240. Its modular structure shortens the assembly and disassembly time. A cooling mechanism is included, which delivers coolant to the spiral copper pipe 610 via the conveying pipe 630. The spirally flowing coolant absorbs heat from inside the metallurgical mold 240 and then returns it to the storage tank 650 via the return pipe 660, achieving cyclic cooling of the metallurgical mold 240. The combined cooling and heat dissipation mechanisms provide comprehensive cooling of the metallurgical mold 240, resulting in uniform and efficient cooling. After cooling, the temperature difference in the metallurgical mold 240 is small, reducing thermal stress concentration and extending its lifespan, thus improving the practicality of the device.

[0030] Specifically, a support pad 231 is provided at the bottom of the positioning cover plate 230; by providing the support pad 231, the contact part between the positioning cover plate 230 and the metallurgical mold 240 is buffered and supported, ensuring the stability of the installation of the metallurgical mold 240.

[0031] Specifically, the stamping mechanism includes a mounting bracket 310, which is fixed to the side wall of the mounting base 100 by bolts. A hydraulic rod A320 is fixed to the top of the mounting bracket 310, and a drive disk 330 is fixed to the bottom of the hydraulic rod A320. A stamping die 340 is fixed to the bottom of the drive disk 330. By setting up the stamping mechanism, the hydraulic rod A320 drives the drive disk 330 to move downward, and the movement of the drive disk 330 drives the stamping die 340 to move. The stamping die 340, the metallurgical mold 240 and the support mechanism work together to stamp and form metal powder.

[0032] Specifically, the support mechanism includes a mounting plate 410, which is fixed to the bottom of the mounting base 100 by bolts. A hydraulic rod B420 is fixed to the bottom of the mounting plate 410, and a support mold 430 is fixed to the top of the hydraulic rod B420. The support mold 430 is slidably connected to the metallurgical mold 240. By providing the support mechanism, during the stamping operation, the hydraulic rod B420 drives the support mold 430 to move, moving the support mold 430 into the metallurgical mold 240.

[0033] Specifically, the heat dissipation mechanism includes a cooling plate 510, which is fixed to the inner wall of the mounting base plate 210. A controller 520 is fixed to the side wall of the mounting base plate 210 by bolts, and multiple cooling fans 530 are fixed to the bottom of the mounting base plate 210 by bolts.

[0034] Working Principle: During use, the control panel 110 controls the operation of the device. The metallurgical mold 240 is placed on the mounting base plate 210. The positioning cover plate 230 is aligned with and inserted into multiple magnetic positioning posts 220. The magnetic positioning posts 220 magnetically fix the positioning cover plate 230, allowing for convenient installation and disassembly of the metallurgical mold 240. The modular structure shortens the assembly and disassembly time. Hydraulic rod A320 drives the drive plate 330 downwards, which in turn moves the stamping die 340. The stamping die 340, the metallurgical mold 240, and the support mechanism work together to stamp the metal powder. During stamping, hydraulic rod B420 moves the support die 430 inside the metallurgical mold 240. The metallurgical mold 240 and the support die 430 work together to support the metal powder. The cooling plate 510 and controller 52... The cooling system works in conjunction with the heat dissipation system to cool the bottom of the metallurgical mold 240. A cooling fan 530 cools the heat generated by the cooling plate 510 during operation. During installation, the feed end of the spiral copper tube 610 is inserted into connector A631, and the return end is inserted into connector B661, facilitating easy connection and installation. The circulation pump 620 starts, drawing coolant stored in the storage tank 650 through the suction pipe 621 and delivering it to the spiral copper tube 610 through the delivery pipe 630. The spirally flowing coolant absorbs heat from inside the metallurgical mold 240 and is then returned to the storage tank 650 through the return pipe 660, achieving a circulating cooling operation for the metallurgical mold 240. The combined cooling and heat dissipation mechanisms provide comprehensive, uniform, and efficient cooling for the metallurgical mold 240.
