Description

Technical Field

[0001] The invention relates to the technical field of metal mold quenching, in particular to quenching equipment for metal mold manufacturing. Background Art

[0002] Quenching is an important process in metal heat treatment, which aims to improve the hardness and strength of the heated metal material by rapidly cooling it (usually above its critical temperature). This process is particularly critical for the manufacture of metal molds, because the mold needs to withstand high temperature, high pressure and wear during operation, so its performance directly affects the quality and life of the finished product. In mold manufacturing, quenching is an important process in metal heat treatment, which mainly improves the hardness and strength of the metal material heated to a certain temperature by rapidly cooling it. Quenching can not only improve the hardness of the metal, but also improve its wear resistance and fatigue strength, thereby improving the mechanical properties of the material. This process usually involves heating the metal to its critical temperature (i.e., austenitizing temperature), at which temperature the metal's organizational structure changes to form an austenite phase, and then, through rapid cooling, usually using a cooling medium such as water, oil or gas, the temperature of the metal is rapidly reduced to transform it from austenite to martensite.

[0003] During the use of the quenching equipment, since the metal mold on the movable plate needs to be placed in the quenching equipment for processing, it is necessary to keep a distance from the metal mold, otherwise the metal mold that has just been processed will generate high temperature and easily scald the workers. After the metal mold is manufactured, it needs to be quickly water-cooled for quenching, otherwise it will affect the hardness of the metal mold. Summary of the invention

[0004] The disclosed embodiment relates to a quenching device for metal mold manufacturing. After the metal mold on the movable plate is pushed into the quenching device for manufacturing, the electric rod 203 can automatically push the sealing plate upwards, open the front end of the quenching device to facilitate the hook rod to pull out the bearing mesh frame. At this time, the worker is distanced from the metal mold, and the high temperature on the metal mold will not scald the worker. At the same time, the electric cylinder can also automatically push the metal mold into a cold water pool for quenching, and the water in the cold water pool can be replaced at any time. After the metal material is heated to the austenite zone at high temperature, it is rapidly cooled to transform it into martensite. This phase change significantly improves the hardness of the metal. Normally, the hardness of martensite is several levels higher than that of steel in its initial state. Water quenching has a high heat conduction efficiency and can quickly take away the heat from the surface of the metal workpiece. The quenching process can significantly improve the hardness of the metal mold, making it more wear-resistant during use. This hardness improvement can effectively extend the service life of the mold, reduce frequent repairs and replacements caused by wear, and thus reduce production costs.

Four penetrating guide holes are opened on the guide rail frame, and mutually symmetrical positioning blocks are fixedly installed on the inner side wall of the guide rail frame. A hook rod is placed on the notch block of the guide rail frame, and a hook plate is fixedly installed at the rear end of the hook rod.

[0006] In at least some embodiments, a cooling tank is placed in the tank slot at the left end of the equipment platform, a pipe hole is opened at the right end of the cooling tank, and a penetrating collection tank is fixedly installed at the tank hole at the right end of the equipment platform.

[0007] In at least some embodiments, a supporting ring is fixedly mounted on the upper end of the inner side wall of the collection tank, and a filter screen is placed on the supporting ring.

[0008] In at least some embodiments, a sliding door is provided at the front end of the upper end of the quenching device, an anti-slip groove is provided in the middle of the front end of the quenching device, and an electric rod is fixedly installed in the groove at the top of the quenching device.

[0009] In at least some embodiments, a connecting rod is fixedly mounted on the upper end of the electric rod, a sealing plate is fixedly mounted on the lower end of the connecting rod, and an anti-slip strip is fixedly mounted on the bottom of the sealing plate.

[0010] In at least some embodiments, a baffle is fixedly mounted on the side wall at the lower end of the sealing plate, mutually symmetrical track bars are fixedly mounted on the side wall of the inner cavity of the quenching equipment, mutually symmetrical track plates are fixedly mounted on the front side wall of the quenching equipment, and a limiting plate is fixedly mounted on the front end of the track plate.

[0011] In at least some embodiments, a water suction pipe is fixedly connected to the left end of the water pump, and a drainage pipe is fixedly connected to the right end of the water pump.

[0012] In at least some embodiments, four vertically upward guide rods are fixedly installed at the bottom of the inner cavity of the cold water pool, and a retaining ring is rotatably installed on the upper end of the guide rod. A penetrating delivery pipe is fixedly installed at the pipe hole at the right end of the cold water pool.

[0013] The present invention provides a quenching device for metal mold manufacturing, which has the following beneficial effects: When the quenching equipment in the present invention is in use, the metal mold on the movable plate is pushed into the quenching equipment for manufacturing. After completion, the electric rod 203 can automatically push the sealing plate upwards, open the front end of the quenching equipment to facilitate the hook rod to pull out the bearing mesh frame. At this time, the worker is distanced from the metal mold, and the high temperature on the metal mold will not scald the worker. At the same time, the electric cylinder can also automatically push the metal mold into the cold water pool for quenching, and the water in the cold water pool can be replaced at any time. After the metal material is heated to the austenite zone at high temperature, it is rapidly cooled to transform it into martensite. This phase change significantly improves the hardness of the metal. Under normal circumstances, the hardness of martensite is several levels higher than that of steel in its initial state. Water quenching has a high heat conduction efficiency and can quickly take away the heat from the surface of the metal workpiece. The quenching process can significantly improve the hardness of the metal mold, making it more wear-resistant during use. This hardness improvement can effectively extend the service life of the mold, reduce frequent repairs and replacements caused by wear, and thus reduce production costs.

[0014] In addition, use the electric rod to push the connecting rod and the sealing plate upward, then the mouth of the front end of the quenching equipment will open, use the hook plate on the hook rod to hook the front end of the bearing mesh frame and pull it forward, and at the same time the moving plate will slide forward and move out of the quenching equipment. At this time, the track groove on the moving plate will slide on the track plate, and then continue to slide forward to the receiving track frame. It will stop moving forward due to the obstruction of the positioning block, and the sealing plate can also open and close automatically, so that workers can stay away from high-temperature metal molds to avoid being scalded by the high temperature on the metal molds.

[0015] In addition, the water in the cold water pool is discharged into the collection tank through the delivery pipe, and the quenched cold water will fall on the filter net. At this time, the filter net will block and limit the debris in the water, so that the water in the collection tank can be used again after filtering, thereby saving the waste of water resources. Then start the water pump and use the suction pipe to pump up the cold water in the cooling tank, and then deliver it into the cold water pool from the drain pipe, so that the cold water in the cold water pool can continue to quench the metal mold.

[0016] By using the electric cylinder to push the connecting frame and the guide rail frame downward, the metal mold on the load-bearing mesh frame will also move downward. When the metal mold enters the cold water pool, the cold water in the cold water pool will quench the metal mold. Quenching can significantly improve the hardness and wear resistance of the mold material, so that it can still maintain a good shape and performance under high load conditions. The mold with strong wear resistance can withstand wear during long-term use, reduce frequent replacement and repair, and effectively extend the service life. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] Among them, a cooling tank 101 is placed in the tank slot at the left end of the equipment table 1, and cold water is injected into the cold water pool 5 for a long time. A pipe hole is opened at the right end of the cooling tank 101. A penetrating collection tank 102 is fixedly installed at the tank hole at the right end of the equipment table 1. The right end of the delivery pipe 503 is inserted into the collection tank 102. After the cold water in the cold water pool 5 frequently quenches the metal mold, the water temperature in the cold water pool 5 will increase. At this time, the water in the cold water pool 5 is discharged into the collection tank 102 through the delivery pipe 503. The quenched cold water will fall on the filter 104, and the filter 104 will block and limit the debris in the water to prevent the debris from entering the inner cavity of the collection tank 102.

A supporting ring 103 is fixedly installed on the upper end of the inner wall of the collection tank 102, and the filter 104 is placed on the supporting ring 103. The filter 104 can be disassembled by grabbing it and lifting it up, and then the debris on the filter 104 can be cleaned.

[0024] Among them, a sliding door 201 is provided at the front end of the upper end of the quenching equipment 2, and a sealing plate 205 is slidably installed at the sliding door 201. An anti-slip groove 202 is provided in the middle part of the front end of the quenching equipment 2, and an electric rod 203 is fixedly installed in the groove at the top of the quenching equipment 2. A connecting rod 204 is fixedly installed on the upper end of the electric rod 203, and a sealing plate 205 is fixedly installed on the lower end of the connecting rod 204. The electric rod 203 is used to push the connecting rod 204 and the sealing plate 205 upward, and then the mouth of the front end of the quenching equipment 2 will be opened, so that the bearing net frame 303 in the quenching equipment 2 can be conveniently entered or pulled out, and the connecting rod 204 and the sealing plate 205 are pulled downward by the electric rod 203, and the anti-slip strip 206 will be inserted into the anti-slip groove 202, and the sealing plate 205 is used to close the front end of the quenching equipment 2, and the anti-slip strip 206 is fixedly installed on the bottom of the sealing plate 205. 206 is inserted in the anti-slip groove 202, and a baffle 207 is fixedly installed on the side wall at the lower end of the sealing plate 205. During the upward movement of the sealing plate 205, the baffle 207 is blocked by the front end of the quenching equipment 2 and cannot continue to move upward, so that the supporting net frame 303 can enter or be pulled out of the quenching equipment 2. Mutually symmetrical track bars 208 are fixedly installed on the side walls of the inner cavity of the quenching equipment 2, and mutually symmetrical track plates 209 are fixedly installed on the front side walls of the quenching equipment 2. A limiting plate 210 is fixedly installed at the front end of the track plate 209, and the bottom of the limiting plate 210 is in contact with the top side wall of the connecting track frame 603. During the upward movement of the connecting track frame 603, it is blocked and restricted by the limiting plate 210, and the connecting track frame 603 will stop moving upward. At this time, the connecting track frame 603 will be on the same horizontal line with the track plate 209, so that the movable plate 3 can slide back and forth conveniently.

[0025] The left end of the water pump 4 is fixedly connected with a water pumping pipe 401, which penetrates the pipe hole at the right end of the cooling tank 101. The right end of the water pump 4 is fixedly connected with a drain pipe 402, which penetrates the pipe hole at the left end of the cold water pool 5. The water pump 4 is started to pump the cold water in the cooling tank 101 with the water pumping pipe 401, and then transported into the cold water pool 5 from the drain pipe 402, so that the cold water in the cold water pool 5 can quench the metal mold entering. Four vertically upward guide rods 5 are fixedly installed at the bottom of the inner cavity of the cold water pool 5. 01, the guide hole 604 on the connecting track frame 603 is slidably mounted in the guide rod 501. When the connecting track frame 603 slides up and down, the guide hole 604 on the connecting track frame 603 is restricted by the guide rod 501, and the connecting track frame 603 can only slide up and down to prevent the connecting track frame 603 from being offset when sliding up and down. A retaining ring 502 is rotatably installed on the upper end of the guide rod 501, and the retaining ring 502 is attached to the side wall of the connecting track frame 603. A through-conveying pipe 503 is fixedly installed at the pipe hole at the right end of the cold water pool 5.

[0026] Among them, a penetrating electric cylinder 601 is fixedly installed at the circular hole in the middle of the support frame 6, and a connecting frame 602 is fixedly installed at the lower end of the electric cylinder 601, and a receiving track frame 603 is fixedly installed at the lower end of the connecting frame 602, and a notch block is fixedly installed at the front end of the receiving track frame 603. When the metal mold on the movable plate 3 and the bearing net frame 303 slides onto the receiving track frame 603, the electric cylinder 601 is used to push the connecting frame 602 and the receiving track frame 603 downward. At this time, the metal mold on the bearing net frame 303 will also move downward. When the metal mold enters the cold water pool 5, the cold water in the cold water pool 5 will quench the metal mold. Four penetrating guide holes 604 are opened on the receiving track frame 603, and mutually symmetrical positioning blocks 605 are fixedly installed on the inner side wall of the receiving track frame 603. A hook rod 606 is placed on the notch block of the receiving track frame 603, and a hook plate is fixedly installed at the rear end of the hook rod 606.

[0027] Embodiment 2, based on embodiment 1, as Figure 1 and Fig. 9 As shown, ear plates are fixedly installed at the lower ends of the four corner side walls of the support frame 6, and through bolts are rotatably inserted in the middle of the four ear plates of the support frame 6. The ear plates and bolts are removed, and then the lower end of the support frame 6 is fixedly welded to the equipment table 1 to firmly restrict the support frame 6. In this way, the support frame 6 will not fall over when touched, avoiding the loosening of the bolts after long-term use, making it impossible to continue to fix the support frame 6, and also saving the cost of parts.

[0028] The working principle of this embodiment is as follows: when in use, the track groove 301 on the movable plate 3 is slidably installed on the track bar 208. When the metal mold on the bearing mesh frame 303 is heated, the electric rod 203 is used to push the connecting rod 204 and the sealing plate 205 upwards. At this time, the mouth of the front end of the quenching equipment 2 will be opened, and the hook plate on the hook rod 606 is hooked on the front end of the bearing mesh frame 303 and pulled forward. At the same time, the movable plate 3 will also slide forward and move out of the quenching equipment 2. At this time, the track groove 301 on the movable plate 3 will slide on the track plate 209, and then continue to slide forward to the receiving track frame 603. It will stop moving forward due to the obstruction of the positioning block 605, and then the electric cylinder 601 is used to push the connecting frame 602 and the receiving track frame 603 downwards. The metal mold on the supporting mesh frame 303 will also move downward. When the metal mold enters the cold water pool 5, the cold water in the cold water pool 5 will quench the metal mold. The water pump 4 is started to pump the cold water in the cooling tank 101 with the pumping pipe 401, and then the cold water is transported into the cold water pool 5 from the drain pipe 402, so that the cold water in the cold water pool 5 can quench the entering metal mold. After the cold water in the cold water pool 5 frequently quenches the metal mold, the water temperature in the cold water pool 5 will increase. At this time, the water in the cold water pool 5 is discharged into the collection tank 102 through the delivery pipe 503, and the quenched cold water will fall on the filter screen 104. At this time, the filter screen 104 will block and limit the debris in the water to prevent the debris from entering the inner cavity of the collection tank 102.
