[0002] Powder metallurgy is a process technology that uses metal powder (or a mixture of metal powder and non-metal powder) as raw materials, and then shapes and sinters to manufacture metal materials, composite materials and various types of products. In the manufacturing process of powder metallurgy molds, heat treatment is an important step, and the cooling process after heat treatment has a crucial impact on the performance and quality of the mold.

[0003] However, traditional natural cooling methods are inefficient. The mold remains at high temperatures for too long, affecting its performance indicators, reducing production efficiency, and increasing costs. In addition, the mold lifting and lowering operations mostly rely on manual labor, which is labor-intensive and poses safety hazards. At the same time, it is difficult to ensure the stability of the mold placement, which affects the cooling effect.

[0004] Therefore, in view of the fact that the traditional natural cooling method is inefficient and the mold lifting and lowering depends on manual operation, resulting in low production efficiency, high cost, great safety hazards and unstable cooling effect, a powder metallurgy mold heat treatment cooling device can be designed. This device not only achieves a more efficient mold cooling effect, but also makes the mold lifting and lowering operation more stable and controllable, greatly improving the safety and convenience of operation.

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1 - Figure 5 This utility model provides an embodiment of a powder metallurgy mold heat treatment cooling device, comprising a housing 1, a workbench 2 inside the housing 1, a water pump 3 and a water tank 4 at the upper end of the housing 1, the inlet of the water pump 3 being connected to the outlet of the water tank 4 via a hose, a cavity 5 inside the workbench 2, a lifting assembly for lifting the mold at the bottom of the cavity 5, a movable plate 6 inside the lifting assembly, a mold adapted to the cavity 5 placed on the upper end of the movable plate 6, the movable plate 6 driving the mold to move vertically, a water cooling assembly for cooling the mold inside the housing 1, the water cooling assembly being located on the upper side of the cavity 5, the water cooling assembly being connected to the outlet of the water pump 3 via a hose, and a water outlet pipe 7 at the front end of the workbench 2. The housing 1 is the main structure of the entire device, the workbench 2 is a component inside the housing 1 used to support and fix the mold, and the water pump 3 and water tank 4 constitute the device. The water system consists of a water tank 4 for storing cooling water, and a water pump 3 for pumping water from the tank and delivering it to the water-cooling assembly via a hose. The hose connects the tank 4, pump 3, and water-cooling assembly, and has good flexibility and sealing properties, capable of withstanding pressure and bending while preventing water leakage. The lifting assembly is used to raise and lower the mold. Driven by the lifting assembly, the moving plate 6 can move the mold vertically, thus achieving the lifting and lowering operation of the mold. The water-cooling assembly is located on the upper side of the cavity 5 of the workbench 2 and is used to cool the mold. It is connected to the outlet port of the pump 3 via a hose, receives cooling water from the pump 3, and then sprays the cooling water evenly onto the mold surface to quickly reduce the mold temperature. The outlet pipe 7 is located at the front end of the workbench 2 to discharge the used cooling water and prevent water accumulation inside the workbench 2.

[0021] Please see Figure 1 and Figure 4In this embodiment, the lifting assembly includes a bearing seat 8. A middle bearing seat 8 is provided at the bottom of the cavity 5. A screw 9 is rotatably connected inside the bearing seat 8. A threaded sleeve 10 is threadedly connected to the upper end of the screw 9. The upper end of the threaded sleeve 10 is fixedly connected to the lower end of the moving plate 6. A transmission rod 11 is rotatably connected to the front end of the worktable 2. A knob 12 is provided at the end of the transmission rod 11. A transmission structure is provided between the screw 9 and the transmission rod 11. The transmission structure includes a driving bevel gear 13. The driving bevel gear 13 is fixedly connected to the outer wall of the transmission rod 11. A driven bevel gear 14 is fixedly connected to the outer wall of the screw 9. The driving bevel gear 13 and the driven bevel gear 14 are meshed. Water passage holes 15 are symmetrically opened through the upper end of the moving plate 6. The bearing seat 8 is a hollow fixed structure used to support and position the screw 9. The upper end of the screw 9 has a thread. The screw 9 is used for threaded connection with the threaded sleeve 10. By rotating the screw 9, the threaded sleeve 10 and the moving plate 6 above it can be driven to move vertically. The transmission rod 11 is a long rod-shaped structure. By rotating the knob 12, the transmission rod 11 can be driven to rotate. The transmission structure is the component connecting the transmission rod 11 and the screw 9. It is responsible for transmitting the rotational motion of the transmission rod 11 to the screw 9. The driving bevel gear 13 is fixedly connected to the outer wall of the transmission rod 11 and rotates with the transmission rod 11. It has an inclined tooth surface for meshing with the driven bevel gear 14. The driven bevel gear 14 is fixedly connected to the outer wall of the screw 9. Its tooth surface matches the tooth surface of the driving bevel gear 13. Through the meshing connection, the rotational motion of the transmission rod 11 is transmitted to the screw 9. The water passage holes 15 are small holes that are symmetrically opened on the upper end of the moving plate 6. They allow cooling water to pass through the moving plate 6 and then be discharged outside the worktable 2 through the water outlet pipe 7.

[0022] Please see Figure 1 and Figure 5 In this embodiment, the water-cooling assembly includes a crossbeam 16, which is fixedly connected inside the housing 1. A retaining ring 17 is provided in the middle of the crossbeam 16, and a spray pipe 18 is provided inside the retaining ring 17. A nozzle 19 is provided at the outlet of the spray pipe 18, and a T-connector 20 is connected to the inlet of the spray pipe 18. The inlet of the T-connector 20 is connected to the outlet port of the water pump 3 through a flexible hose. The crossbeam 16 is a sturdy strip structure, and the retaining ring 17 is a ring structure located in the middle of the crossbeam 16. The function of the retaining ring 17 is to position and fix the spray pipe 18, ensuring that the spray pipe 18 can be stably suspended below the crossbeam 16 and maintain a certain spray angle and range. The retaining ring 17 has a certain elasticity and adjustability to adapt to spray pipes 18 of different sizes. The spray pipe 18 is a slender pipe structure that passes through the retaining ring 17 and is suspended below the crossbeam 16. The internal channel of the spray pipe 18 is used to transport cooling water, and its outlet is equipped with a nozzle 19 to spray the cooling water evenly onto the mold surface.

[0023] During operation, the mold is first placed on the moving plate 6, and then the knob 12 is rotated. This action causes the transmission rod 11 to start rotating. The rotation of the transmission rod 11 drives the rotation of the driving bevel gear 13 connected to it. Through the precise meshing between the gears, the driven bevel gear 14 also rotates. The rotation of the driven bevel gear 14 further drives the screw 9 to rotate. Utilizing the interaction of the threads, the threaded sleeve 10 drives the moving plate 6 to slowly descend until the mold is completely inserted into the cavity 5 in the worktable 2. At this time, the water pump 3 is started. The water pump 3 draws out the cooling water from the water tank 4 and pumps it into the spray pipe 18. The nozzles 19 on the spray pipe 18 then spray out cooling water to effectively cool the mold. At the same time, after the cooling water flows through the mold, it continues to flow through the water passage hole 15 opened on the moving plate 6 and is finally discharged smoothly through the water outlet pipe 7 at the front end of the worktable 2.

[0024] Through the above steps, this solution achieves more efficient mold cooling by integrating water-cooling and lifting components. The water-cooling component, with its crossbeam 16, retaining ring 17, and spray pipe 18, ensures uniform spraying of cooling water, improves cooling efficiency, and reduces cooling time. Meanwhile, the lifting component, through the cooperation of screw 9, threaded sleeve 10, and transmission structure, makes the mold lifting operation more stable and controllable. Compared with manual handling, it greatly improves the safety and convenience of operation, solving the problems of low efficiency, high cost, significant safety hazards, and unstable cooling effect caused by the reliance on manual lifting of molds in traditional natural cooling methods.

[0025] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
