Description

A cooling mechanism for a stamping die Technical Field

[0001] This utility model relates to the field of electronic precision mold technology, specifically to a cooling mechanism for a stamping die. Background Technology

[0002] In the electronics manufacturing industry, stamping dies are widely used in the production of precision components such as metal casings, connector terminals, and shielding covers. As electronic products become increasingly miniaturized and precise, die temperature control during the stamping process has become a key factor affecting product quality and production efficiency. Traditional stamping dies, during high-speed continuous stamping, generate significant frictional heat due to the plastic deformation of the metal, leading to a rapid increase in die temperature. This can cause problems such as die thermal deformation, material adhesion, and limited production efficiency.

[0003] A search revealed a utility model patent with publication number CN221983704U, which discloses a cooling mechanism for a stamping die. The mechanism includes a stamping device body and a cooling component mounted on the surface of the stamping device body. By mounting the cooling component on the stamping device body and by placing an inner mold shell inside the outer mold shell and a cold water tank inside the outer mold shell at its bottom, heat from the inner mold shell is conducted to the cold water tank. The water in the cold water tank dissipates the heat conducted from the surface of the inner mold shell, thus achieving heat dissipation and cooling of the stamping die. The water quickly removes heat from the stamping die. The structure is simple, directly removing heat through cold water. Combined with a fixing component, the inner mold shell, equipped with a locking block, is engaged with a slot inside the outer mold shell during use. A rod further secures the inner mold shell to the outer mold shell, making it more stable during stamping operations and resulting in better performance.

[0004] The aforementioned patent merely sets a cooling component on the stamping device body, sets an inner mold shell inside the mold shell, and sets a cold water tank inside the mold shell and located on the bottom surface of the inner mold shell. The heat of the inner mold shell is conducted to the cold water tank, and the water in the cold water tank consumes the heat conducted from the surface of the inner mold shell, thereby achieving the effect of heat dissipation and cooling of the stamping mold. However, it cannot fully wash and clean the metal dust and residual mold release agent on the surface of the mold cavity, making online cleaning inconvenient and requiring manual intervention.

[0005] Therefore, it is necessary to invent a cooling mechanism for stamping dies to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a cooling mechanism for a stamping die. By filling the cooling pipes with rust-preventive coolant, the heat conducted from the inner shell surface of the die body is dissipated, thereby achieving the effect of heat dissipation and cooling of the stamping die. The rust-preventive coolant can quickly remove the heat from the stamping die. Through the design of the spiral water channel cooling pipes and spray holes, the metal dust and residual mold release agent adhering to the inner wall surface of the die body can be cleaned online. This solves the problem that the existing technology cannot fully clean the metal dust and residual mold release agent on the surface of the die cavity, making online cleaning inconvenient and requiring manual intervention.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a cooling mechanism for a stamping die, comprising a die base and a die body. The die body is fixedly mounted on the top of the die base. A cooling pipe is fixedly mounted on the inner wall of the die body. A liquid extraction pipe is provided on one side of the cooling pipe, extending to the outside of the die body. The liquid extraction pipe is fixedly connected to the die body. A liquid pump is fixedly installed between the liquid extraction pipe and the die body. A drain pipe is provided on the other side of the cooling pipe, extending to the outside of the die body. The drain pipe is fixedly connected to the die body. A valve body is fixedly installed between the drain pipe and the die body. A set of spray holes is provided on each of the four sides of the inner wall of the die body. The number of spray holes in a set is set to six. A nozzle is fixedly engaged inside each spray hole, and the nozzle is fixedly connected to the cooling pipe.

[0008] Preferably, the bottom of the front, rear, and both sides of the mold body is provided with inclined guide ports, which are connected to the inner cavity of the mold body.

[0009] Preferably, a flow guide groove is provided on the top of the mold base, and a filter box is fixedly provided on the bottom of the mold base.

[0010] Preferably, the inside of the guide channel is provided with a liquid outlet pipe, which is fixedly connected to the filter box, and the lower end of the liquid outlet pipe extends into the filter box.

[0011] Preferably, a filter frame is movably engaged inside the filter box, and a limiting plate is fixedly connected to the top wall inside the filter box. A slot is provided on the side of the limiting plate, and the slot matches the filter frame.

[0012] Preferably, the filter box has a material inlet on its side, and the material inlet matches the filter frame.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] 1. By filling the cooling pipes with rust-preventive coolant, the heat conducted from the inner shell surface of the mold body is consumed, thereby achieving the effect of heat dissipation and cooling of the stamping mold. The rust-preventive coolant can quickly remove the heat from the stamping mold. Through the design of the spiral water channel cooling pipes and spray holes, the metal powder and residual release agent adhering to the inner wall surface of the mold body can be flushed and cleaned online. The flushed metal powder and agent are guided into the guide channel through the inclined guide port, and discharged into the filter box along the guide channel and the liquid outlet pipe for filtration and repeated cooling and reuse. This reduces manual intervention, provides long-term rust prevention, and effectively protects the high-precision surface of the mold body.

[0015] 2. The coolant containing metal powder and reagents is filtered through the filter frame, so that the coolant placed in the filter box can be reused. The slot and the material outlet limit and position the filter frame, making it easy to remove and clean it later. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides a cooling mechanism for a stamping die, as shown in Figures 1-5, including a die base 1 and a die body 2. The die body 2 is fixedly mounted on the top of the die base 1. A cooling pipe 3 is fixedly mounted on the inner wall of the die body 2. A liquid extraction pipe 4 is provided on one side of the cooling pipe 3, extending to the outside of the die body 2 and fixedly connected to the die body 2. A liquid pump 5 is fixedly installed between the liquid extraction pipe 4 and the die body 2. A drain pipe 6 is provided on the other side of the cooling pipe 3, extending to the other side of the die body 2 and fixedly connected to the die body 2. A valve body 7 is fixedly installed between the drain pipe 6 and the die body 2. A cooling mechanism is provided on all four sides of the inner wall of the die body 2. A set of six spray holes 8 are provided. A nozzle 801 is fixedly attached inside each spray hole 8 and is fixedly connected to the cooling pipe 3. The valve body 7 draws coolant from the filter box 11 to fill the cooling pipe 3 with coolant, allowing the coolant to quickly remove heat from the mold body 2. The cooling pipe 3 has a spiral water channel structure to increase the cooling area. When it is necessary to replace the coolant in the filter box 11 and the cooling pipe 3, the valve body 7 and the liquid pump 5 are turned on simultaneously until the liquid in the cooling pipe 3 and the filter box 11 is drained. The coolant is preferably an oil-based coolant, such as mineral oil with extreme pressure additives, which will not cause rust when rinsing the inside of the mold body 2.

[0026] Inclined guide ports 9 are provided on the bottom of the front, rear and both sides of the mold body 2. The inclined guide ports 9 are connected to the inner cavity of the mold body 2. The coolant sprayed by the nozzle 801 will carry metal powder and concentrate in the guide groove 10 through the inclined guide ports 9.

[0027] The top of the mold base 1 is provided with a guide groove 10, and the bottom of the mold base 1 is fixedly provided with a filter box 11. The coolant carrying metal powder flows in the guide groove 10 and is guided to enter the filter box 11 through the liquid outlet pipe 12 for filtration.

[0028] The inside of the guide channel 10 is provided with a liquid outlet pipe 12, which is fixedly connected to the filter box 11, and the lower end of the liquid outlet pipe 12 extends into the filter box 11.

[0029] The filter box 11 is internally fitted with a filter frame 13. The top wall of the filter box 11 is fixedly connected to a limiting plate 14. The limiting plate 14 has a slot 15 on its side. The slot 15 matches the filter frame 13. The slot 15 can filter the metal dust carried by the passing coolant. The coolant is stored in the filter box 11 and reused. The impurities are filtered onto the surface of the filter frame 13.

[0030] The filter box 11 has a material inlet 16 on its side, which matches the filter frame 13. When it is necessary to clean the impurities filtered out of the filter frame 13, they can be taken out through the material inlet 16 for cleaning.

[0031] The working principle of this practical application is as follows:

[0032] When the mold body 2 needs to be cooled, the liquid pump 5 is turned on and the coolant stored in the filter box 11 is drawn out using the liquid extraction pipe 4. The coolant fills the interior of the cooling pipe 3 and is used to remove heat from the mold body 2. During the flow of the coolant in the cooling pipe 3, it will be sprayed out through the nozzle 801 at a certain pressure, directly washing away the metal dust and mold release agent residues on the inner surface of the mold body 2. The washed-down coolant, carrying dust and residues, is concentrated in the guide channel 10 through the inclined guide port 9. It is then guided into the liquid outlet pipe 12 through the flow channel in the guide channel 10 and finally enters the filter box 11. It is then filtered through the filter frame 13. The processed coolant is then stored in the filter box 11 for subsequent recycling.

[0033] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
