Description

Technical Field

[0001] The present application relates to the technical field of molds, and in particular to a mold structure. Background Art

[0002] In the production process of soft-pack batteries, the aluminum-plastic film needs to be wrapped around the coiled core coated with positive and negative electrode slurries by stamping and encapsulated under a certain temperature and pressure.

[0003] Related technology can refer to the Chinese patent with announcement number CN217573228U, which discloses an aluminum-plastic film punching die, including a pressing assembly and a punching assembly, the pressing assembly includes a pressing plate and a concave template, the pressing plate is provided with a punching hole, the concave template is provided with a forming hole, the concave template is used to clamp the aluminum-plastic film together when it is buckled with the pressing plate, and the pressing plate is also provided with a positioning hole, the punching assembly includes a bottom plate, a mold core and a positioning pin, the mold core is arranged on the bottom plate, the positioning pin is arranged on the bottom plate, and the bottom plate is used to buckle to the side of the pressing plate away from the concave template, so that the positioning pin is penetrated in the positioning hole, and then the mold core is penetrated with punching holes and forming holes in sequence. In this way, by matching the positioning pin with the positioning hole, the mold core can pass through the punching hole and the forming hole in sequence without friction, so as to perform a punching process on the aluminum-plastic film, which can avoid the debris generated by wear from contaminating the aluminum-plastic film, and at the same time, it can avoid damaging the mold, thereby improving the service life of the mold.

[0004] With regard to the above-mentioned related technologies, at present, the structure of the punching mold is such that after punching, the mold is often easily attached to the inner wall of the lower mold and is difficult to remove. During the ejection process of the aluminum-plastic film, there is no lubrication function between the mold and the lower mold, which can easily cause the top aluminum-plastic film to wrinkle and crack. At the same time, the friction between the mold and the lower mold during punching will generate a certain amount of heat. During the shaping process, it is necessary to wait for it to cool down before demolding. During the cooling process, the device will stop running, thereby affecting the punching efficiency. Summary of the invention

[0005] The purpose of this application is to provide a mold structure.

[0006] In the first aspect, the present application provides a mold structure adopting the following technical solution: A mold structure comprises a workbench, a No. 1 base is arranged on one side of the top of the workbench, a lower mold is connected to the top center of the No. 1 base by bolts, a mold core is arranged in the middle of the lower mold, and limiting rods are arranged at the edge of the lower mold, a fixed frame is connected to the top of the workbench, a cylinder is arranged at the bottom of the fixed frame, an upper mold frame is connected to the bottom end of the cylinder by bolts, a punch is arranged at the bottom of the upper mold frame, a telescopic cylinder is arranged in the middle of the upper mold frame, the bottom end of the telescopic cylinder passes through the upper mold frame and is connected to the punch, limiting rings are arranged on both sides of the upper mold frame, the limiting rings match the limiting rods, a movable cavity is arranged in the middle of the lower mold, and the movable cavity A through slot is arranged at the top of the cavity, and the through slot is connected to the mold core. A connecting plate is arranged in the middle of the movable cavity. An ejector pin is arranged on the top of the connecting plate, and the top of the ejector pin is connected to a ejector block through the through slot. An electric telescopic rod is arranged on the bottom inner wall of the movable cavity, and the top output end of the electric telescopic rod is connected to the connecting plate. The electric telescopic rod drives the connecting plate to move up and down, and the lifting of the connecting plate drives the ejector pin to move synchronously. The lifting movement of the ejector pin drives the ejector block to move synchronously. A temperature sensor is arranged on one side of the top of the movable cavity, and a controller is arranged on one side of the lower mold. The controller is connected to the temperature sensor and the electric telescopic rod through wires.

[0007] By adopting the above technical scheme, the soft-pack battery core aluminum plastic can be placed on the surface of the lower mold during punching, and the upper mold frame is pushed downward by the cylinder to perform translational movement. The upper mold frame stops moving after moving to the soft-pack battery core aluminum plastic, thereby fixing the soft-pack battery core aluminum plastic. After fixing, the punch is pushed downward by the telescopic cylinder to perform translational movement, thereby pushing the soft-pack battery core aluminum plastic to cooperate with the mold core of the lower mold for punching and shaping. At the same time, the limit ring and the limit rod play a limiting role to ensure the accuracy of the punch and the lower mold. After the mold is formed, the current mold temperature can be detected by the temperature sensor. When the temperature drops to a safe range, the signal is transmitted to the controller. The controller controls the electric telescopic rod to start, and the electric telescopic rod drives the connecting plate to move up and down. The lifting of the connecting plate drives the ejector pin to move synchronously. The lifting movement of the ejector pin drives the ejector block to move synchronously, thereby ejecting the mold. The appropriate temperature is detected by the temperature sensor to eject the mold, so that the mold can be ejected after molding, and it is avoided that the mold is ejected when the temperature is high, thereby affecting the molding effect and causing defects such as wrinkling and cracking of the product.

[0008] Nozzles are arranged and embedded at the inner edge of the top block, the bottom end of the nozzle is connected with a shunt pipe, one end of the shunt pipe is penetrated and arranged inside the ejector pin, the end of the shunt pipe away from the nozzle is connected with a main pipe through a connecting plate, an oil storage tank is embedded at one side of the bottom of the lower mold, one end of the main pipe away from the shunt pipe is connected to the oil storage tank, a micro pump is arranged at one side of the main pipe close to the oil storage tank, a trigger switch is arranged at one side of the top of the connecting plate, and the trigger switch is connected to the micro pump through an electric wire.

[0009] By adopting the above technical scheme, when the electric telescopic rod pushes the connecting plate, the ejector pin and the ejector block to lift the mold upward, when the top of the connecting plate contacts the active cavity, the ejector block pushes the mold to the top edge of the mold core, and at the same time, the trigger switch abuts against the inner wall of the active cavity to trigger the control of the micro pump to start. The lubricating oil in the oil storage tank can be quantitatively pumped into the main pipe through the micro pump, and then transmitted to the branch pipe through the main pipe, and then the lubricating oil is sprayed onto the inner wall of the mold core through the nozzle. Multiple groups of nozzles spray in all directions so that the inner wall of the mold core is evenly covered with lubricating oil, thereby playing a lubricating role to facilitate the subsequent ejection of the mold. The spraying of lubricating oil prevents the mold from being difficult to eject, thereby causing wrinkles and cracks on the product. At the same time, when the nozzle sprays the lubricating oil, the mold is still on the top of the ejector block. At this time, it plays the role of a cover plate to prevent the lubricating oil from being sprayed to the outside of the mold core and causing pollution.

[0010] A No. 2 base is arranged on one side of the No. 1 base, and a lower mold is also arranged on the top of the No. 2 base. The No. 1 base and the No. 2 base are connected by a connecting strip, and a threaded moving block is connected to the center of the bottom end of the connecting strip by bolts.

[0011] By adopting the above technical solution, the No. 1 base is matched with the No. 2 base so that the two sets of lower dies can alternately perform mold punching work with the punch, and the threaded moving block plays a connecting role.

[0012] A strip groove is provided on one side of the upper surface of the workbench, the threaded moving block is embedded in the strip groove, a screw rod is connected to the middle of the strip groove through a bearing, the screw rod passes through the threaded moving block, and the outer wall of the screw rod is threadedly connected to the threaded moving block.

[0013] By adopting the above technical solution, the strip groove plays a limiting role so that the threaded moving block can slide in the strip groove but cannot rotate. The screw rod can be driven by a servo motor to rotate in the strip groove, thereby driving the threaded moving block to perform translational movement.

[0014] A driving cavity is provided on one side of the strip groove, and a servo motor is connected to the interior of the driving cavity. The output end of the servo motor is connected to the lead screw. The servo motor drives the lead screw to rotate. The rotation of the lead screw drives the threaded moving block to translate in the strip groove. The movement of the threaded moving block drives the connecting bar to move synchronously. The movement of the connecting bar drives the No. 1 base and the No. 2 base to move synchronously.

[0015] By adopting the above technical scheme, when a group of diversion punching is completed and the upper mold frame is lifted, the servo motor can be used to drive the No. 1 base and the No. 2 base to perform synchronous translational movement, thereby driving the lower mold on the top of the No. 1 base where the punching is completed to move out for cooling, and at the same time drive the lower mold on the top of the No. 2 base to move to the top of the upper mold frame for subsequent punching work, thereby improving the working efficiency of the device to avoid the mold affecting the progress of subsequent punching during the cooling process, and enabling the mold after the punching is completed to have sufficient cooling time, thereby avoiding defects such as cracking of the mold due to insufficient cooling time.

[0016] Cooling boxes are arranged on both sides of the workbench, and auxiliary cooling mechanisms are arranged inside the cooling boxes. The auxiliary cooling mechanisms include a cooling fan, a semiconductor refrigerator, a temperature insulation pad and a second temperature sensor.

[0017] By adopting the above technical solution, the mold that has completed the punching will be driven by the servo motor into the cooling box for cooling and shaping, and the mold will be auxiliary cooled by the auxiliary cooling mechanism.

[0018] A cooling fan is arranged on the top of the cooling box, a semiconductor refrigerator is arranged on one side of the cooling fan, a thermal insulation pad is bonded to the inner wall of the cooling box, a No. 2 temperature sensor is arranged on the inner wall of one side of the cooling box, and an air curtain is arranged on the top of the feed port of the cooling box.

[0019] By adopting the above technical scheme, air cooling can be performed through the cooling fan. The position of the cooling fan is the air inlet, and the opening of the cooling box is the exhaust end of the cooling fan. The airflow blown out by the cooling fan is cooled and then merged into the air flow curtain formed by the wind curtain machine and then discharged. The semiconductor refrigerator plays a cooling role so that the inside of the cooling box maintains a low temperature. The internal temperature of the cooling box can be monitored in real time through the No. 2 temperature sensor. At the same time, the insulation pad plays an insulation role to prevent low temperature from escaping. The wind curtain machine blows air to the bottom of the opening of the cooling box to form an air flow curtain to block the exchange of air inside and outside the cooling box, thereby maintaining the temperature inside the cooling box and reducing heat loss. In combination with the insulation pad, the thermal insulation effect of the cooling box is improved.

[0020] A control box is arranged on one side of the top of the cooling box, and the control box is connected to the second temperature sensor, the cooling fan and the semiconductor refrigerator through electric wires.

[0021] By adopting the above technical solution, the power of the cooling fan and the semiconductor refrigerator can be controlled by the control box in conjunction with the No. 2 temperature sensor, thereby controlling the temperature inside the cooling box. The power of the semiconductor refrigerator and the cooling fan changes synchronously in equal proportion, so that the set standard temperature can be continuously maintained in the cooling box, so as to cool the mold within a safe temperature and avoid the increase of thermal stress caused by too fast cooling effect. If these stresses exceed the tensile strength of the material, they may cause the mold to crack or deform.

[0022] A camera is arranged on the top of the feed port of the cooling box, a warning light is arranged on one side of the top of the camera, the camera and the warning light are connected to the control box through electric wires, and a box door is arranged on one side of the cooling box.

[0023] By adopting the above technical solution, the formed mold can be taken out by opening the box door. When the lower mold moves back and forth out of the cooling box, it will enter and exit the camera. The camera can take a picture of the surface of the lower mold and transmit the signal to the control box. The control box processes and detects internally whether the lower mold is deformed, worn or cracked, and other abnormal conditions. When an abnormality is detected in the lower mold, the control warning light will light up to remind the staff to maintain or replace it in time to avoid affecting the subsequent mold molding.

[0024] In summary, the present application includes at least one of the following beneficial technical effects: 1. When the electric telescopic rod pushes the connecting plate, ejector pin and ejector block upward to lift the mold, when the top of the connecting plate contacts the active cavity, the ejector block pushes the mold to the top edge of the mold core, and at the same time, the trigger switch abuts against the inner wall of the active cavity to trigger the control micro pump to start. The micro pump can quantitatively pump the lubricating oil in the oil storage tank into the main pipe, and then transmit it to the shunt pipe through the main pipe, and then spray the lubricating oil to the inner wall of the mold core through the nozzle. Multiple groups of nozzles spray in all directions so that the inner wall of the mold core is evenly covered with lubricating oil, thereby playing a lubricating role to facilitate the subsequent ejection of the mold. The spraying of lubricating oil prevents the mold from being difficult to eject, thereby causing wrinkles and cracks on the product. At the same time, when the nozzle sprays the lubricating oil, the mold is still on the top of the ejector block. At this time, it acts as a cover plate to prevent the lubricating oil from spraying to the outside of the mold core and causing pollution; 2. When a group of diversion punching is completed and the upper mold frame is lifted, the servo motor can be used to drive the No. 1 base and the No. 2 base to perform synchronous translational movement, thereby driving the lower mold on the top of the No. 1 base that has completed the punching to move out for cooling, and at the same time drive the lower mold on the top of the No. 2 base to move to the top of the upper mold frame for subsequent punching work, thereby improving the working efficiency of the device to avoid the mold affecting the progress of subsequent punching during the cooling process, and enabling the punched mold to have sufficient cooling time to avoid defects such as mold cracking due to insufficient cooling time.

A fixed frame 101 is connected to the top of the workbench 1, a cylinder 102 is arranged at the bottom of the fixed frame 101, an upper mold frame 6 is connected to the bottom end of the cylinder 102 by bolts, a punch 7 is arranged at the bottom of the upper mold frame 6, a telescopic cylinder 8 is arranged in the middle of the upper mold frame 6, and the bottom end of the telescopic cylinder 8 passes through the upper mold frame 6 and is connected to the punch 7, and limiting rings 9 are arranged on both sides of the upper mold frame 6, and the limiting rings 9 match the limiting rods 5. An active cavity 10 is arranged in the middle, and a through slot 11 is arranged on the top of the active cavity 10, which is connected to the mold core 4. A connecting plate 12 is arranged in the middle of the active cavity 10, and an ejector pin 13 is arranged on the top of the connecting plate 12. The top of the ejector pin 13 passes through the through slot 11 and is connected to an ejector block 14. An electric telescopic rod 15 is arranged on the inner wall of the bottom of the active cavity 10, and the top output end of the electric telescopic rod 15 is connected to the connecting plate 12. The electric telescopic rod 15 drives the connecting plate 12 to move up and down, and the lifting of the connecting plate 12 drives the ejector pin 13 to move synchronously, and the lifting movement of the ejector pin 13 drives the ejector block 14 to move synchronously. A temperature sensor is arranged on one side of the top of the active cavity 10. The temperature sensor 16 is provided on one side of the lower mold 3, and a controller 17 is provided on one side of the lower mold 3. The controller 17 is connected to the temperature sensor 16 and the electric telescopic rod 15 by wires. The lower mold 3 matches the upper mold frame 6. When punching, the soft-pack battery core aluminum plastic can be placed on the surface of the lower mold 3, and the upper mold frame 6 is pushed downward by the cylinder 102 to perform a translational movement. The upper mold frame 6 stops moving after moving to the soft-pack battery core aluminum plastic, thereby playing a role in fixing the soft-pack battery core aluminum plastic to avoid the problem of wrinkling of the edge due to excessive pressure. After fixing, the telescopic cylinder 8 pushes the punch 7 to move downward, thereby pushing the soft-pack battery core aluminum plastic to cooperate with the mold core 4 of the lower mold 3 to punch and shape the pit, and at the same time, the limit ring 9 and the limit The positioning rod 5 plays a limiting role to ensure the accuracy of the punch 7 and the lower mold 3. After the mold is formed, the current mold temperature can be detected by the temperature sensor 16. When the temperature drops to a safe range, the signal is transmitted to the controller 17. The controller 17 controls the electric telescopic rod 15 to start, and the electric telescopic rod 15 drives the connecting plate 12 to move up and down. The lifting and lowering of the connecting plate 12 drives the ejector pin 13 to move synchronously.

The appropriate temperature is detected by the temperature sensor 16 to eject the mold so that the mold can be ejected after molding, so as to avoid ejecting the mold when the temperature is high, thereby affecting the molding effect and causing defects such as wrinkling and cracking of the product.

[0028] A nozzle 18 is arranged and embedded at the inner edge of the ejector block 14, and a shunt pipe 19 is connected to the bottom end of the nozzle 18. One end of the shunt pipe 19 passes through the interior of the ejector pin 13, and the end of the shunt pipe 19 away from the nozzle 18 passes through the connecting plate 12 and is connected to the main pipe 20. An oil storage tank 21 is embedded on one side of the bottom of the lower mold 3, and the end of the main pipe 20 away from the shunt pipe 19 is connected to the oil storage tank 21. A micro pump 22 is arranged on the side of the main pipe 20 close to the oil storage tank 21, and a trigger switch 23 is arranged on one side of the top of the connecting plate 12. The trigger switch 23 is connected to the micro pump 22 through an electric wire. When the electric telescopic rod 15 pushes the connecting plate 12, the ejector pin 13 and the ejector block 14 upward to lift the mold, the ejector block 14 pushes the mold up when the top of the connecting plate 12 contacts the active cavity 10. To the top edge of the mold core 4, the trigger switch 23 is simultaneously abutted against the inner wall of the active cavity 10, thereby triggering the control micro pump 22 to start. The micro pump 22 can quantitatively pump the lubricating oil in the oil storage tank 21 into the main conduit 20, and then transmit it to the branch pipe 19 through the main conduit 20, and then spray the lubricating oil onto the inner wall of the mold core 4 through the nozzle 18. Multiple groups of nozzles 18 spray in all directions so that the inner wall of the mold core 4 is evenly covered with lubricating oil, thereby playing a lubricating role to facilitate the subsequent ejection of the mold. The spraying of the lubricating oil prevents the mold from being difficult to eject, thereby causing the product to have wrinkles and cracks. At the same time, during the process of the nozzle 18 spraying the lubricating oil, the mold is still on the top of the top block 14. At this time, it acts as a cover plate to prevent the lubricating oil from spraying to the outside of the mold core 4 and causing pollution.

[0029] A No. 2 base 24 is arranged on one side of the No. 1 base 2, and a lower mold 3 is also arranged on the top of the No. 2 base 24. The No. 1 base 2 and the No. 2 base 24 are connected by a connecting strip 25, and a threaded moving block 26 is connected to the center of the bottom end of the connecting strip 25 by bolts. The No. 1 base 2 and the No. 2 base 24 are matched so that the two groups of lower molds 3 can alternately perform mold punching work with the punch 7, and the threaded moving block 26 plays a connecting role.

[0030] A strip groove 27 is provided on one side of the upper surface of the workbench 1, and the threaded moving block 26 is embedded in the strip groove 27. A screw rod 28 is connected to the middle part of the strip groove 27 through a bearing. The screw rod 28 passes through the threaded moving block 26. The outer wall of the screw rod 28 is threadedly connected to the threaded moving block 26. The strip groove 27 plays a limiting role so that the threaded moving block 26 can slide in the strip groove 27 and cannot rotate. The screw rod 28 can be driven by a servo motor 30 to rotate in the strip groove 27, thereby driving the threaded moving block 26 to perform translational movement.

The output end of the servo motor 30 is connected to the screw rod 28. The servo motor 30 drives the screw rod 28 to rotate. The rotation of the screw rod 28 drives the threaded moving block 26 to translate in the strip groove 27. The threaded moving block 26 moves to drive the connecting bar 25 to move synchronously. The connecting bar 25 moves to drive the No. 1 base 2 and the No. 2 base 24 to move synchronously. When a group of diversion pits are completed and the upper mold frame 6 is lifted, the servo motor 30 can be driven to drive the No. 1 base 2 and the No. 2 base 24 to move synchronously, thereby driving the lower mold 3 on the top of the No. 1 base 2 after the pit is completed to move out for cooling, and at the same time drive the lower mold 3 on the top of the No. 2 base 24 to move to the top of the upper mold frame 3 for subsequent pitting work, thereby improving the working efficiency of the device to avoid affecting the progress of subsequent pitting during the cooling process of the mold, and enabling the mold after the pitting is completed to have enough cooling time, thereby avoiding defects such as cracking of the mold due to insufficient cooling time.

[0032] Cooling boxes 31 are provided on both sides of the workbench 1. An auxiliary cooling mechanism 32 is provided inside the cooling box 31. The auxiliary cooling mechanism 32 includes a cooling fan 321, a semiconductor refrigerator 322, an insulation pad 323 and a second temperature sensor 324. The mold that has completed the punching will be driven into the cooling box 31 by the servo motor 30 for cooling and shaping, and the auxiliary cooling mechanism 32 will be used to assist in cooling the mold.

[0033] A cooling fan 321 is provided on the top of the cooling box 31, a semiconductor refrigerator 322 is provided on one side of the cooling fan 321, a temperature insulation pad 323 is bonded to the inner wall of the cooling box 31, a second temperature sensor 324 is provided on one inner wall of the cooling box 31, and an air curtain 37 is provided on the top of the feed port of the cooling box 31. The cooling fan 321 can be used for air cooling. The position of the cooling fan 321 is the air inlet, and the opening of the cooling box 31 is the exhaust end of the cooling fan 321. The airflow blown out by the cooling fan 321 is cooled and merged into the air flow curtain formed by the air curtain 37. The heat is then discharged out through the semiconductor refrigerator 322 to keep the inside of the cooling box 31 at a relatively low temperature. The temperature inside the cooling box 31 can be monitored in real time through the No. 2 temperature sensor 324. At the same time, the insulation pad 323 acts as an insulation to prevent the low temperature from escaping. The wind curtain machine 37 blows air to the bottom of the opening of the cooling box 31 to form an air flow curtain, which blocks the exchange of air between the inside and outside of the cooling box 31, thereby maintaining the temperature inside the cooling box 31 and reducing heat loss. The insulation pad 323 is used to improve the thermal insulation effect of the cooling box 31.

[0034] A control box 33 is provided on one side of the top of the cooling box 31. The control box 33 is connected to the second temperature sensor 324, the cooling fan 321 and the semiconductor refrigerator 322 through electric wires. The control box 33 cooperates with the second temperature sensor 324 to control the power of the cooling fan 321 and the semiconductor refrigerator 322, thereby controlling the temperature in the cooling box 31. The power of the semiconductor refrigerator 322 and the cooling fan 321 changes synchronously in equal proportion, so that the set standard temperature can be continuously maintained in the cooling box 31, so as to cool the mold within a safe temperature and avoid the increase of thermal stress caused by too fast cooling effect. If these stresses exceed the tensile strength of the material, they may cause the mold to crack or deform.

[0035] A camera 34 is provided at the top of the feed port of the cooling box 31, and a warning light 35 is provided on one side of the top of the camera 34. The camera 34 and the warning light 35 are connected to the control box 33 through electric wires. A box door 36 is provided on one side of the cooling box 31. The formed mold can be taken out by opening the box door 36. When the lower mold 3 moves back and forth out of the cooling box 31, it will enter and exit the camera 34. The camera 34 can take a picture of the surface of the lower mold 3 and transmit the signal to the control box 33. The control box 33 processes and detects whether the lower mold is deformed, worn or cracked or other abnormal conditions. When the lower mold 3 is detected to be abnormal, the warning light 35 is controlled to light up to remind the staff to maintain or replace it in time to avoid affecting the subsequent mold molding.

[0036] The implementation principle of the embodiment of the present application is as follows: when punching, the soft-pack battery core aluminum plastic can be placed on the surface of the lower mold 3, and the upper mold frame 6 is pushed downward for translational movement by the cylinder 102. The upper mold frame 6 stops moving after moving to the soft-pack battery core aluminum plastic, thereby fixing the soft-pack battery core aluminum plastic. After fixing, the telescopic cylinder 8 is used to push the punch 7 to move downward for translational movement, thereby pushing the soft-pack battery core aluminum plastic to cooperate with the mold core 4 of the lower mold 3 for punching and shaping. At the same time, the limit ring 9 and the limit rod 5 play a limiting role to ensure the accuracy of the punch 7 and the lower mold 3. After the mold is formed, the current mold temperature can be detected by the temperature sensor 16. When the temperature drops to a safe range, the signal is transmitted to the controller 17. The controller 17 controls the electric telescopic rod 15 to start, and the electric telescopic rod 15 drives the connecting rod 15 to drive ... The connecting plate 12 performs lifting movement, and the lifting of the connecting plate 12 drives the ejector pin 13 to perform synchronous movement, and the lifting movement of the ejector pin 13 pushes the ejector block 14 to perform synchronous movement, thereby ejecting the mold. The temperature sensor 16 detects the appropriate temperature to eject the mold so that the mold can be ejected after molding, thereby avoiding ejecting the mold when the temperature is high, thereby affecting the molding effect and causing defects such as wrinkling and cracking of the product. When the electric telescopic rod 15 pushes the connecting plate 12, the ejector pin 13 and the ejector block 14 to lift the mold upward, when the top of the connecting plate 12 contacts the active cavity 10, the ejector block 14 pushes the mold to the top edge of the mold core 4, and at the same time, the trigger switch 23 abuts against the inner wall of the active cavity 10, thereby triggering the control micro pump 22 to start, and the micro pump 22 can quantitatively discharge the oil in the oil storage tank 21 The lubricating oil is pumped into the main conduit 20, and then transmitted to the branch pipe 19 through the main conduit 20, and then the lubricating oil is sprayed onto the inner wall of the mold core 4 through the nozzle 18. Multiple groups of nozzles 18 spray in all directions so that the inner wall of the mold core 4 is evenly covered with lubricating oil, thereby playing a lubricating role to facilitate the subsequent ejection of the mold. The spraying of lubricating oil prevents the mold from being difficult to eject, thereby causing wrinkles and cracks on the product. At the same time, during the process of the nozzle 18 spraying the lubricating oil, the mold is still on the top of the ejector block 14. At this time, it acts as a cover plate to prevent the lubricating oil from being sprayed to the outside of the mold core 4 and causing pollution. When a group of diversion pits are completed and the upper mold frame 6 is lifted, the servo motor 30 can be used to drive the No. 1 base 2 and the No. 2 base 24 to perform synchronous translational movement, thereby driving the pit to be completed. The lower mold 3 on the top of the No. 1 base 2 is moved out for cooling, and at the same time, the lower mold 3 on the top of the No. 2 base 24 is driven to move to the top of the upper mold frame 3 for subsequent punching work, thereby improving the working efficiency of the device to avoid affecting the progress of subsequent punching during the cooling process of the mold, and enabling the mold after the punching to have enough cooling time to avoid defects such as mold cracking caused by insufficient cooling time. Air cooling can be performed by the cooling fan 321. The position of the cooling fan 321 is the air inlet, and the opening of the cooling box 31 is the exhaust end of the cooling fan 321. The airflow blown out by the cooling fan 321 is cooled and merged into the air flow curtain formed by the air curtain machine 37 and then discharged. The semiconductor refrigerator 322 plays a cooling role so that the inside of the cooling box 31 maintains a low temperature.The internal temperature of the cooling box 31 can be monitored in real time through the second temperature sensor 324. At the same time, the insulation pad 323 plays a role of insulation to prevent low temperature from escaping. The air curtain machine 37 blows air to the bottom of the opening of the cooling box 31 to form an air flow curtain, which blocks the exchange of air inside and outside the cooling box 31, thereby maintaining the temperature inside the cooling box 31 and reducing heat loss. The insulation pad 323 is used to improve the thermal insulation effect of the cooling box 31. The control box 33 and the second temperature sensor 324 can control the power of the cooling fan 321 and the semiconductor refrigerator 322 to control the temperature inside the cooling box 31. The power of the semiconductor refrigerator 322 and the cooling fan 321 are synchronized in equal proportion. The change enables the cooling box 31 to continuously maintain the set standard temperature, so as to cool the mold within a safe temperature and avoid the cooling effect being too fast, which may cause the increase of thermal stress. If these stresses exceed the tensile strength of the material, they may cause the mold to crack or deform. The mold can be taken out by opening the box door 36. When the lower mold 3 moves back and forth out of the cooling box 31, it will enter and exit the camera 34. The camera 34 can take a picture of the surface of the lower mold 3 and transmit the signal to the control box 33. The control box 33 processes and detects whether the lower mold is deformed, worn or cracked, etc. When the lower mold 3 is abnormal, the control warning light 35 is turned on to remind the staff to maintain or replace it in time to avoid affecting the subsequent mold molding.
