Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a stamping mold that can be rapidly cooled. Background Technology

[0002] In modern industrial production, stamping dies are key equipment in the manufacturing industry and are widely used in the automotive, electronics, aerospace and other fields. During the stamping process, the die comes into frequent contact with the high-temperature workpiece, causing the die temperature to rise sharply. If it is not cooled in time, it will not only cause workpiece deformation and a decrease in dimensional accuracy, affecting the product yield, but also accelerate die wear, shorten the die life and increase the production cost of enterprises.

[0003] According to the online patent application number 202121216161.6, a stamping die for a car frame that can be cooled quickly is described. Although the stamping oil used in the forming groove of the stamping die can play a role in lubrication, anti-sticking and cooling, the stamping oil (especially the oil with high viscosity) is easy to remain and accumulate in the complex corners, gaps and vents of the forming groove, forming sludge and oil stains, which will contaminate the outer surface of the stamped products, affect the quality of the products, and increase the workload of subsequent work.

[0004] To address the above problems, this utility model proposes a stamping die that can be cooled quickly. Utility Model Content

A fixing pipe is fixedly connected to the lower end of each water inlet. One end of the fixing pipe is closed. A water inlet pipe is slidably connected to the closed end of the fixing pipe. A piston is fixedly connected to the outer surface of the water inlet pipe. The outer surface of the piston is slidably connected to the inner wall of the fixing pipe.

[0007] Preferably, a spring is fitted onto the outer surface of the water inlet pipe, and the upper and lower ends of the spring are fixedly connected to the lower surface of the disc and the upper surface of the piston, respectively. A support frame is fixedly connected to the lower outer surface of the water inlet pipe, and a second cylinder is arranged above the support frame. The piston rod of the second cylinder is fixedly connected to the upper surface of the support frame, and the cylinder body of the second cylinder is fixedly connected to the lower surface of the base plate. The two ends of the base plate are rotatably connected to the lower end of the lower mold through pins.

[0008] Preferably, a retaining ring is provided on the inner wall of the water inlet.

[0009] Preferably, the air intake pipe has air intake holes arranged in an open array, and the air intake holes are at the same horizontal plane as the upper surface of the base plate.

[0011] Preferably, the lower end of the lower mold has a groove that matches the air inlet pipe.

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

[0013] By incorporating a cooling device, not only is cooling and assisted demolding integrated, but the buoyancy of water also helps the forming mold move upward, effectively reducing the difficulty and time cost of manual or mechanical demolding and improving production efficiency. Moreover, the innovative drainage and drying mechanism uses a cylinder to tilt the base plate for drainage, combined with air blowing through the air inlet pipe to dry the mold, preventing moisture residue from causing mold corrosion or affecting subsequent stamping accuracy and extending the mold's service life. At the same time, the device uses air and water dual-power coordinated operation, which consumes less energy and significantly improves cooling efficiency compared to traditional single cooling methods.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0025] Reference Figures 1-9 A stamping die capable of rapid cooling includes a lower die 1. A cooling device 2 is provided at the lower end of the lower die 1. The cooling device 2 includes a base plate 21. The base plate 21 has arrayed water inlets 20. L-shaped inclined surfaces are provided on both sides of the base plate 21. Air inlets 22 are symmetrically arranged on both sides of the base plate 21. Cylinders 24 are symmetrically arranged on the lower surface of the base plate 21. A disc 23 is slidably connected to the inner wall of each water inlet 20. A fixing pipe 25 is fixedly connected to the lower end of each water inlet 20. One end of the fixing pipe 25 is closed, and a water inlet pipe 26 is slidably connected to the closed end of the fixing pipe 25. The outer surface of the water inlet pipe 26... A piston 28 is fixedly connected to the surface, and the outer surface of the piston 28 is slidably connected to the inner wall of the fixed tube 25. A spring 27 is sleeved on the outer surface of the water inlet pipe 26. The upper and lower ends of the spring 27 are fixedly connected to the lower surface of the disc 23 and the upper surface of the piston 28, respectively. A support frame 29 is fixedly connected to the lower outer surface of the water inlet pipe 26. A cylinder 210 is set above the support frame 29. The piston rod of the cylinder 210 is fixedly connected to the upper surface of the support frame 29. The cylinder body of the cylinder 210 is fixedly connected to the lower surface of the base plate 21. The two ends of the base plate 21 are rotatably connected to the lower end of the lower mold 1 through the pin 211.

[0026] Specifically, after the material in the lower mold 1 is formed, the water pump connected to the water inlet pipe 26 starts supplying water. At the same time, cylinder 210 pulls the water inlet pipe 26 downward through the support frame 29, further driving the disc 23 fixed at the upper end of the water inlet pipe 26 to move, releasing the sealing effect between the disc 23 and the water inlet 20. The water source enters the water inlet 20 through the water inlet pipe 26 and the water outlet at its upper end, and enters the space formed by the base plate 21 and the lower mold 1 through the water inlet 20. After the water source enters the mold, the surface of the mold that first contacts the water source begins to cool down. As more and more cooling water passes through the water inlet 20, the mold is cooled down and also lifted by the buoyancy of the water, which to a certain extent reduces the temperature of the mold. The difficulty of removing the mold; after the mold is removed, the piston rod of one cylinder 24 retracts and the piston rod of the other cylinder 24 extends. The base plate 21 rotates along the center of the pin 211. One end of the base plate 21 moves up into the forming groove of the lower mold 1, and the other end of the base plate 21 descends. At this time, the water in the forming groove is discharged. After the water is completely discharged, the air inlet pipe 22 starts to blow air onto the upper surface of the base plate 21 under the action of the air supply pump. Some of the water that entered the air inlet pipe 22 is blown out by force. The air inlet pipe 22 continues to blow air until the upper surface of the base plate 21 is completely dry. The moisture on the inner wall of the forming groove dries quickly under the intervention of the high-speed flowing gas. The cylinder 24 returns to its original state, and the air inlet pipe 22 stops supplying air.

[0027] The aforementioned cooling device 2 not only integrates cooling and assisted demolding, but also utilizes the buoyancy of water to help the forming mold move upward, effectively reducing the difficulty and time cost of manual or mechanical demolding and improving production efficiency. Moreover, the innovative drainage and drying mechanism uses cylinder 24 to tilt the base plate 21 for drainage, combined with air blowing through the air inlet pipe 22 to dry the mold, preventing moisture residue from causing mold corrosion or affecting subsequent stamping accuracy and extending the mold's service life. At the same time, the device adopts dual-powered air and water operation, which consumes less energy and significantly improves cooling efficiency compared to traditional single cooling methods.

[0028] In this embodiment, a retaining ring 201 is provided on the inner wall of the water inlet 20.

[0029] Specifically, when the water pump supplies water, the water flow is rapid and the impact force is large. The setting of the retaining ring 201 prevents the water flow through the inlet 20 from entering the interior of the molding tank at a high speed, reduces the impact force of the cooling water, and further ensures the yield of the molding mold.

[0030] In this embodiment, the air intake pipe 22 has air intake holes arranged in an array, and the air intake holes are at the same level as the upper surface of the base plate 21.

[0031] Specifically, after the cooling water in the molding tank is discharged, the air inlet pipe 22 is connected to a high-pressure air source. Since the air inlet holes arrayed on the air inlet pipe 22 are at the same level as the upper surface of the base plate 21, the high-pressure gas can be ejected at high speed in a direction parallel to the base plate 21. These high-speed airflows directly act on the residual cooling water on the base plate 21, using the impact force of the airflow to quickly blow the residual liquid to both sides of the base plate 21, accelerating the discharge of the liquid along the inclined surface. On the other hand, the horizontally sprayed airflow will form an air curtain in the space between the base plate 21 and the lower mold 1, quickly carrying away the moisture generated by the evaporation of residual water and accelerating the drying process. At the same time, when some cooling water accidentally flows into the air inlet pipe 22, the high-speed airflow can impact in the opposite direction through the air inlet holes, quickly blowing out the water accumulated in the pipe, avoiding pipe blockage or corrosion caused by water accumulation.

[0032] In this embodiment, the surface of the inclined side of the base plate 21 is set as an arc shape, and the center of the arc shape is the same as the rotation center of the base plate 21.

[0033] Specifically, when the base plate 21 rotates around the pin 211 under the drive of the cylinder 24, the surface of the inclined side of the base plate 21 is set as an arc surface, and the center of the arc surface coincides with the rotation center of the base plate 21. This allows the arc surface of the base plate 21 to maintain a uniform gap with the inner wall of the forming groove of the lower mold 1 during rotation. This design brings two advantages: First, when the base plate 21 rotates to the arc surface side and enters the forming groove, a smooth transition drainage channel is formed between the arc surface on the other side and the groove wall. Cooling water can flow quickly into the L-shaped inclined surface along the arc surface, avoiding liquid accumulation at the corners. Second, during the resetting process of the base plate 21, the smooth rotation trajectory of the arc surface can effectively prevent collision or scratching with the inner wall of the forming groove, protect the surface precision of the mold, and extend the service life of the mold.

[0034] In this embodiment, the lower end of the lower mold 1 is provided with a groove that matches the air inlet pipe 22.

[0035] Specifically, the groove design provides safe space for the effective rotation of the intake pipe 22.

[0036] Operating principle:

[0037] In use, after the material in the lower mold 1 is formed, the water pump connected to the water inlet pipe 26 starts supplying water. At the same time, cylinder 210 pulls the water inlet pipe 26 downward through the support frame 29, further driving the disc 23 fixed at the upper end of the water inlet pipe 26 downward, releasing the sealing effect between the disc 23 and the water inlet 20. The water source enters the water inlet 20 through the water inlet pipe 26 and the water outlet at its upper end, and enters the space formed by the base plate 21 and the lower mold 1 through the water inlet 20. After the water source enters the mold, the surface of the mold that first contacts the water source begins to cool down. As more and more cooling water passes through the water inlet 20, the mold is cooled down and also lifted by the buoyancy of the water, which to a certain extent reduces the temperature of the mold. The difficulty of removing the mold; after the mold is removed, the piston rod of one cylinder 24 retracts and the piston rod of the other cylinder 24 extends. The base plate 21 rotates along the center of the pin 211. One end of the base plate 21 moves up into the forming groove of the lower mold 1, and the other end of the base plate 21 descends. At this time, the water in the forming groove is discharged. After the water is completely discharged, the air inlet pipe 22 starts to blow air onto the upper surface of the base plate 21 under the action of the air supply pump. Some of the water that entered the air inlet pipe 22 is blown out by force. The air inlet pipe 22 continues to blow air until the upper surface of the base plate 21 is completely dry. The moisture on the inner wall of the forming groove dries quickly under the intervention of the high-speed flowing gas. The cylinder 24 returns to its original state, and the air inlet pipe 22 stops supplying air.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
