Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and in particular to an automatic die-casting equipment for the housing of a new energy vehicle controller. Background Technology

[0002] The housing of a new energy vehicle controller is an important component of the controller system, mainly serving to protect internal electronic components, dissipate heat, provide electromagnetic shielding, and provide structural support. As the technical requirements for various indicators of new energy vehicles continue to increase, the processing of controller housings is developing towards integration, lightweighting, efficient heat dissipation, and intelligence. The production of controller housings is a comprehensive process that integrates materials science, precision manufacturing, and automation technology. Generally, die casting and other production processes are used in the production of housings.

[0003] Existing patent CN115592086A discloses a controller housing die-casting equipment, including a fixed mold mechanism and a moving mold mechanism mounted on a die-casting machine frame. The moving mold mechanism is equipped with a mold-closing buffer, and a locking mechanism is provided at the mold-closing position of the moving mold mechanism and the fixed mold mechanism. The locking mechanism includes a locking component located at the mold-closing position of the fixed mold and a positioning component located at the mold-closing position of the moving mold and cooperating with the locking component. This mechanism can mitigate the impact force caused by the die-casting machine applying force to the moving mold, eliminate the rebound force caused by excessive impact due to the excessive movement speed of the moving mold when it contacts the fixed mold, and ensure a tight seal between the moving mold and the fixed mold, thereby improving the sealing effect between the moving mold and the fixed mold. This effectively avoids the leakage of molten metal caused by gaps between the moving mold and the fixed mold, reducing safety hazards.

[0004] The above structure can achieve the die-casting effect on the controller housing. However, the contact impact force is large when the moving mold and the fixed mold come into contact, resulting in significant wear on both molds with each contact. After prolonged operation, damage gaps gradually appear on the contact surfaces of the moving and fixed molds. During mold closing, molten metal will still flow out. After mold closing, when injecting high-pressure molten metal, the increased pressure can easily cause a slight lateral displacement of the moving mold, leading to partial separation between the moving and fixed molds and causing molten metal to flow out again, greatly reducing the product yield. After die-casting, the moving and fixed molds need to be separated to remove the product. The position of the moving mold movement is difficult to control precisely each time. If the movement is too small, the product cannot be removed; if the movement is too large, the product can be removed, but energy consumption and production costs increase, the service life of the device is reduced, the control accuracy of the device is compromised, and the stability of automation is decreased.

[0005] Therefore, how to provide an automatic die-casting equipment for the housing of a new energy vehicle controller is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] One objective of this invention is to provide an automatic die-casting device for a new energy vehicle controller housing. This automatic die-casting device for a new energy vehicle controller housing includes a processing table, a fixed mold body on the processing table, an injection pipe for injecting molten metal on the fixed mold body, a moving mold assembly adapted to the fixed mold body on the processing table, a pulling assembly on the moving mold assembly, a deflection assembly on the processing table, a lateral buffer assembly on the deflection assembly, an inclined buffer assembly between the deflection assembly and the processing table, a connecting assembly between the pulling assembly and the deflection assembly, and a connection between the fixed mold body and the moving mold assembly. The mold is equipped with a snap-fit ​​assembly, and a pressing assembly is provided on the fixed mold body. A transmission assembly is provided between the pressing assembly and the deflection assembly. During mold closing, the moving mold assembly descends, forcing the pulling assembly to press down. This causes the lateral buffer assembly and the tilting buffer assembly to resist the downward pressure and achieve a buffering effect. At the same time, the transmission assembly moves, forcing the pressing assembly to drive the snap-fit ​​assembly to form a snap-fit, limiting the lateral displacement of the moving mold assembly during molten metal injection. During mold opening, the moving mold assembly moves upward, causing the pulling assembly to generate an upward lifting force. When the lateral buffer assembly and the tilting buffer assembly move to their maximum reasonable limits, the product removal position is determined.

[0007] Preferably, the moving mold assembly includes a support frame disposed on the processing table, a hydraulic lifting rod mounted on the support frame, and a moving mold body adapted to the fixed mold body at the output end of the hydraulic lifting rod.

[0008] Preferably, the pulling assembly includes a support plate disposed on the moving mold body, a pulling rod disposed on the support plate, a pressure sensor mounted on the pulling rod, and a pulling block disposed on the pulling rod.

[0009] Preferably, the deflection assembly includes a shaft connected to the processing table by a bearing, a first deflection rod and a second deflection rod adapted to the first deflection rod are connected to the shaft by a bearing, and the second deflection rod has a receiving groove for accommodating the first deflection rod.

[0010] Preferably, the lateral buffer assembly includes a lateral buffer cylinder hinged to the first deflection rod, a piston is provided inside the lateral buffer cylinder, a lateral buffer rod is provided on the piston and passing through the lateral buffer cylinder, a baffle is provided on the lateral buffer rod, the baffle is hinged to the second deflection rod, and a lateral buffer spring sleeved on the outer ring of the lateral buffer rod is provided between the lateral buffer cylinder and the baffle.

[0011] Preferably, the tilting buffer assembly includes a tilting buffer cylinder hinged to the processing table, a piston inside the tilting buffer cylinder, a tilting buffer rod passing through the tilting buffer cylinder on the piston, a second baffle on the tilting buffer rod, the second baffle hinged to the first deflection rod or the second deflection rod, and a tilting buffer spring sleeved on the outer ring of the tilting buffer rod between the tilting buffer cylinder and the second baffle.

[0012] Preferably, the connecting assembly includes a support block hinged to the end of the first deflection rod or the second deflection rod, a connecting rod is provided on the support block, a sliding groove is provided on the connecting rod, a load-bearing rod adapted to the sliding groove is provided on the pulling block, and a top block for limiting excessive movement of the support block is provided on the first deflection rod or the second deflection rod.

[0013] Preferably, the snap-fit ​​assembly includes a limiting block disposed on the moving mold body, a guide block disposed on the fixed mold body, and a snap-fit ​​block adapted to the limiting block slidably disposed on the guide block. The snap-fit ​​block passes through the guide block, wherein when the snap-fit ​​block is inserted into the limiting block, a snap-fit ​​limiting effect is formed.

[0014] Preferably, the extrusion assembly includes a fixed plate disposed on the fixed mold body, a transmission rod is connected to the fixed plate by a bearing, a rotating disk is fixedly sleeved on the transmission rod, an extrusion rod is hinged to the rotating disk at an off-center position, and the extrusion rod is hinged to the snap-fit ​​block.

[0015] Preferably, the transmission assembly includes a mounting rod disposed at one end of the deflection rod one or the deflection rod two, the mounting rod being provided with a sector rack, the center of the sector rack being located in the length direction of the shaft, and a transmission gear being fixedly sleeved on the transmission rod to mesh with the sector rack.

[0016] The beneficial effects of this invention are as follows: In this invention, during the production of the controller housing, the injection pipe is connected to the molten metal delivery system. During the die-casting process, before mold closing, the moving mold assembly is activated. The moving mold assembly moves downward, gradually approaching the fixed mold body. Simultaneously, the moving mold assembly drives the pulling assembly downward, which in turn drives the connecting assembly. Due to the ingenious design of the connecting assembly, it is in a retracted state. When the front section of the moving mold assembly descends, the deflection assembly, the lateral buffer assembly, and the tilting buffer assembly do not move. Before the moving mold assembly contacts the fixed mold body, it continues to move downward. Under the action of the connecting assembly, the pulling assembly exerts a downward pressure on the connecting assembly, forcing the deflection assembly to deflect, causing the lateral buffer assembly and the tilting buffer assembly to move accordingly. The movement of the moving mold assembly, along with the opposing forces generated by the lateral and tilting buffer components, slows its descent and transfers some of the downward pressure to the machining table, thus buffering the moving mold assembly and effectively preventing it from rapidly impacting the fixed mold body. Simultaneously, the deflection of the deflection component drives the transmission component to rotate, which in turn drives the extrusion component, which in turn drives the locking component. This locking component effectively limits and engages the moving mold assembly with the fixed mold body, reducing lateral displacement during molten metal injection. During die casting, molten metal is injected between the moving mold assembly and the fixed mold body through the injection pipe. Under high temperature and pressure, the die casting process is completed, allowing the molten metal to cool and form the desired product. After die casting, the parts are separated... When the mold is in operation, the moving mold assembly is activated, and it moves upward. Under the action of the lateral buffer assembly and the tilting buffer assembly, the deflection assembly drives the transmission assembly to move in the opposite direction, causing the extrusion assembly to pull back the locking assembly. This causes the locking assembly to release the moving mold assembly from the fixed mold body. The moving mold assembly continues to move upward, causing the pulling assembly to pull the connecting assembly. The connecting assembly is in the extended state until it is in its maximum state. Then, the pulling assembly pulls the connecting assembly, causing the deflection assembly to deflect inward. The lateral buffer assembly and the tilting buffer assembly move to their maximum reasonable limits, and the moving mold assembly stops moving. The position where the moving mold assembly stops at this point is the product removal height position, and the operator can then remove the product. In summary, this application provides a novel energy... The automatic die-casting equipment for automotive controller housings can distribute the downward pressure force to the processing table during mold closing, reducing the contact impact force between the moving mold assembly and the fixed mold body, and buffering the contact force to avoid large wear during rapid contact and prevent molten metal leakage. At the same time, it can lock and limit the moving mold assembly and the fixed mold body, reducing the lateral displacement of the moving mold assembly during molten metal injection, preventing partial separation of the moving mold assembly and the fixed mold body, and further preventing molten metal leakage. After die casting, it can achieve precise control of the retraction of the moving mold assembly, avoiding insufficient or excessive movement, thereby reducing energy consumption and production costs, increasing the service life of the equipment, improving the control accuracy of the equipment, and enhancing automation stability.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention. Example

[0020] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 , Figure 9 and Figure 10 As shown, an automatic die-casting equipment for a new energy vehicle controller housing according to the present invention includes a processing table 1, a fixed mold body 2 disposed on the processing table 1, an injection pipe 3 for injecting molten metal disposed on the fixed mold body 2, a moving mold assembly 4 adapted to the fixed mold body 2 disposed on the processing table 1, a pulling assembly 5 disposed on the moving mold assembly 4, a deflection assembly 6 disposed on the processing table 1, a lateral buffer assembly 7 disposed on the deflection assembly 6, an inclined buffer assembly 8 disposed between the deflection assembly 6 and the processing table 1, a connecting assembly 9 disposed between the pulling assembly 5 and the deflection assembly 6, and a snap-fit ​​assembly 10 disposed between the fixed mold body 2 and the moving mold assembly 4. The mold 2 is equipped with an extrusion assembly 11, and a transmission assembly 12 is provided between the extrusion assembly 11 and the deflection assembly 6. During mold closing, the moving mold assembly 4 descends, forcing the pulling assembly 5 to press down, so that the lateral buffer assembly 7 and the tilting buffer assembly 8 resist the downward pressure to achieve a buffering effect. At the same time, the transmission assembly 12 moves, forcing the extrusion assembly 11 to drive the locking assembly 10 to form a locking, limiting the lateral displacement of the moving mold assembly 4 when injecting molten metal. During mold opening, the moving mold assembly 4 moves upward, so that the pulling assembly 5 generates an upward lifting force. When the lateral buffer assembly 7 and the tilting buffer assembly 8 move to their maximum reasonable limit, the product removal position is determined.

[0021] Working principle: During the production of the controller housing, the injection pipe 3 is connected to the molten metal delivery system. During the die casting process, before mold closing, the moving mold assembly 4 is activated. The moving mold assembly 4 moves downward, gradually approaching the fixed mold body 2. Simultaneously, the moving mold assembly 4 drives the pulling assembly 5 to move downward, which in turn drives the connecting assembly 9. Due to the ingenious design of the connecting assembly 9, it is in a retracted state. When the front section of the moving mold assembly 4 descends, the deflection assembly 6, the lateral buffer assembly 7, and the tilting buffer assembly 8 do not move. Before the moving mold assembly 4 contacts the fixed mold body 2, the moving mold assembly 4 continues to move downward. Under the action of connecting component 9, pulling component 5 exerts a downward pressure on connecting component 9, forcing deflection component 6 to deflect, causing corresponding movement of lateral buffer component 7 and tilting buffer component 8. This results in lateral buffer component 7 and tilting buffer component 8 generating a counterforce, causing moving mold component 4 to descend slowly and transferring part of the downward pressure to processing table 1, thereby achieving a buffering effect on moving mold component 4 and effectively preventing moving mold component 4 from rapidly impacting and contacting fixed mold body 2. At the same time, the deflection of deflection component 6 drives transmission component 12 to rotate, and transmission component 12 drives extrusion component 1. 1. Movement: The extrusion component 11 drives the locking component 10 to move, achieving a limiting locking effect between the moving mold component 4 and the fixed mold body 2, reducing the lateral displacement of the moving mold component 4 during molten metal injection. During die casting, molten metal is injected between the moving mold component 4 and the fixed mold body 2 through the injection pipe 3. Under high temperature and high pressure, the die casting process is completed, allowing the molten metal to cool and form the desired product. After die casting is completed, during mold separation, the moving mold component 4 is activated, moving upwards. Under the action of the lateral buffer component 7 and the tilting buffer component 8, the deflection component 6 drives the transmission component 12 to move in the opposite direction. The extrusion component 11 pulls back the locking component 10, causing the locking component 10 to release the moving mold component 4 from the fixed mold body 2. The moving mold component 4 continues to move upward, causing the pulling component 5 to pull the connecting component 9. The connecting component 9 is in the unfolded state until the connecting component 9 is in the maximum state. The pulling component 5 then pulls the connecting component 9, causing the connecting component 9 to drive the deflection component 6 to deflect inward. The lateral buffer component 7 and the tilt buffer component 8 move to their maximum reasonable limits, and the moving mold component 4 stops moving. At this time, the position where the moving mold component 4 stops is the product removal height position, and the staff can remove the product.In summary, the automatic die-casting equipment for the housing of a new energy vehicle controller disclosed in this application can disperse the downward pressure force to the processing table 1 during mold closing, reducing the contact impact force between the moving mold assembly 4 and the fixed mold body 2, and achieving a buffering effect on the contact force. This avoids excessive wear during rapid contact and prevents molten metal from flowing out. Simultaneously, the equipment provides locking and limiting between the moving mold assembly 4 and the fixed mold body 2, reducing the lateral displacement of the moving mold assembly 4 during molten metal injection, preventing partial separation of the moving mold assembly 4 from the fixed mold body 2, and further preventing molten metal from flowing out. After die casting, the equipment can achieve precise control of the retraction of the moving mold assembly 4, avoiding insufficient or excessive movement, thereby reducing energy consumption and production costs, increasing the service life of the device, improving the control accuracy of the device, and enhancing automation stability.

[0027] like Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 8 As shown, the automatic die-casting equipment for the housing of a new energy vehicle controller according to the present invention includes a connecting component 9 comprising a support block 901 hinged to the end of a deflection rod 602 or a deflection rod 603. A connecting rod 902 is provided on the support block 901, and a sliding groove 903 is provided on the connecting rod 902. A load-bearing rod 904 adapted to the sliding groove 903 is provided on the pulling block 504.

[0028] like Figure 2 , Figure 3 and Figure 9 As shown, the automatic die-casting equipment for the housing of a new energy vehicle controller according to the present invention includes a snap-fit ​​assembly 10 comprising a limiting block 1001 disposed on a moving mold body 403, a guide block 1002 disposed on a fixed mold body 2, and a snap-fit ​​block 1003 adapted to the limiting block 1001 slidably disposed on the guide block 1002, the snap-fit ​​block 1003 penetrating the guide block 1002, wherein when the snap-fit ​​block 1003 is inserted into the limiting block 1001, a snap-fit ​​limiting effect is formed.

[0029] like Figure 2 and Figure 9As shown, the automatic die-casting equipment for the housing of a new energy vehicle controller according to the present invention includes an extrusion assembly 11 comprising a fixed plate 1101 disposed on a fixed mold body 2, a transmission rod 1102 connected to the fixed plate 1101 by a bearing, a rotating disk 1103 fixedly sleeved on the transmission rod 1102, and an extrusion rod 1104 hinged to the rotating disk 1103 at an off-center position, the extrusion rod 1104 being hinged to a snap-fit ​​block 1003.

[0030] like Figure 3 , Figure 4 and Figure 10 As shown, the automatic die-casting equipment for the housing of a new energy vehicle controller according to the present invention includes a transmission component 12 comprising a mounting rod 1201 disposed at the end of a deflection rod 1 602 or a deflection rod 2 603, a sector rack 1202 disposed on the mounting rod 1201, the center of the sector rack 1202 being located in the length direction of the shaft 601, and a transmission gear 1203 meshing with the sector rack 1202 being fixedly sleeved on the transmission rod 1102.

[0031] Working principle: During the production of the controller housing, the injection pipe 3 is connected to the molten metal delivery system. During the die casting process, before mold closing, the hydraulic lifting rod 402 is activated. The output end of the hydraulic lifting rod 402 drives the moving mold body 403 to move downward, continuously approaching the fixed mold body 2. The downward movement of the moving mold body 403 drives the support plate 501 to move downward. The support plate 501 drives the pull rod 502 and pressure sensor 503 to move downward, causing the pull block 504 to move downward. The pull block 504 drives the load-bearing... As rod 904 moves downward, under the action of slide groove 903, load-bearing rod 904 drives connecting rod 902 to move around the hinge point. Since load-bearing rod 904 moves within slide groove 903, deflection rod one 602 and deflection rod two 603 do not move. The two connecting rods 902 overlap and are in a contracted state. When the front section of moving mold body 403 descends, deflection rod one 602, deflection rod two 603, transverse buffer assembly 7 and inclined buffer assembly 8 do not move. This is the rapid descent stage. Before the moving mold body 403 contacts the fixed mold body 2, this process is the later stage of descent, i.e., the slow descent phase. The moving mold body 403 continues to move downward. Because the top block 905 presses against the support block 901, the support block 901 and the connecting rod 902 no longer rotate. As the moving mold body 403 continues to descend, the load-bearing rod 904 forces the downward pressure of the load-bearing rod 904 to act on the connecting rod 902, the support block 901, the top block 905, the deflection rod 1 602, and the deflection rod 2 603. At point 3, since deflector rod 1 (602) and deflector rod 2 (603) are connected to shaft 601 by bearings, deflector rod 1 (602) and deflector rod 2 (603) will deflect outwards, that is, the angle between deflector rod 1 (602) and deflector rod 2 (603) increases. This increases the distance between the transverse buffer cylinder 701 and the baffle 1 (703), causing the transverse buffer rod 702 to extend within the transverse buffer cylinder 701. The transverse buffer spring 704 is stretched, and at the same time, the tilting buffer cylinder 80... The distance between 1 and baffle 2 803 decreases, causing the inclined buffer rod 802 to retract within the inclined buffer cylinder 801. The inclined buffer spring 804 is compressed, and the support block 901 moves outward along with the deflection rod 1 602 and the deflection rod 2 603, causing the two connecting rods 902 to move laterally relative to each other. Due to the action of the transverse buffer cylinder 701, baffle 1 703, transverse buffer rod 702 and transverse buffer spring 704, the downward pressing force is dispersed in the horizontal direction and a reaction force is provided. Similarly, the action of the inclined buffer cylinder 801, baffle 2 803, inclined buffer rod 802 and inclined buffer spring 804 disperses the downward pressing force in the horizontal and vertical directions and provides a reaction force, forcing part of the downward pressing force to be dispersed onto the processing table 1, forcing the moving mold body 403 to descend slowly, thereby achieving a buffering effect on the moving mold body 403, effectively avoiding rapid impact contact between the moving mold body 403 and the fixed mold body 2, and avoiding wear at the contact port. Simultaneously, the deflection of deflector rod 1 602 and deflector rod 2 603 causes mounting rod 1201 to rotate around the axis of shaft 601, forcing mounting rod 1201 to drive sector rack 1202 to rotate. Sector rack 1202 drives transmission gear 1203 to rotate. Transmission gear 1203 drives transmission rod 1102 to rotate. Transmission rod 1102 drives rotating disk 1103 to rotate. Rotating disk 1103 drives pressing rod 1104 to move forward. Under the guidance of guide block 1002, pressing rod 1104 drives snap-fit ​​block 1003 to insert into the limit position. Within block 1001, when the moving mold body 403 and the fixed mold body 2 are fully closed, the locking block 1003 is fully inserted into the limiting block 1001, achieving lateral limiting between the locking block 1003 and the limiting block 1001, and achieving lateral limiting locking between the moving mold body 403 and the fixed mold body 2, effectively reducing the lateral displacement of the moving mold body 403 when injecting molten metal; during die casting, molten metal is injected between the moving mold body 403 and the fixed mold body 2 through the injection pipe 3, and the die casting process is completed under high temperature and high pressure, so that the molten metal cools down to form the desired product; After die casting is completed, during mold separation, the hydraulic lifting rod 402 is activated in reverse. The output end of the hydraulic lifting rod 402 drives the moving mold body 403 to move upward, continuously moving away from the fixed mold body 2. The moving mold body 403 drives the support plate 501, the pull rod 502, the pressure sensor 503, the pull block 504, and the load-bearing rod 904 to move upward. As the downward pressure gradually decreases, the transverse buffer spring 704 and the tilt buffer spring 804 need to return to their original state, causing the transverse buffer rod 702 to retract within the transverse buffer cylinder 701, thus reducing the distance between the transverse buffer cylinder 701 and the first baffle 703. The transverse buffer spring 704 returns to its original state. Similarly, the tilt buffer rod 802 extends within the tilt buffer cylinder 801, and the tilt buffer spring 804 returns to its original state. The distance between the tilt buffer cylinder 801 and the second baffle 803 increases, forcing the deflection rod 602 and the deflection rod... The second deflection rod 603 deflects inward, that is, the angle between the first deflection rod 602 and the second deflection rod 603 decreases. The deflection of the first deflection rod 602 and the second deflection rod 603 causes the mounting rod 1201 to rotate around the axis of the shaft 601, which forces the mounting rod 1201 to drive the sector rack 1202 to rotate. The sector rack 1202 drives the transmission gear 1203 to rotate. The rotation of the transmission gear 1203 drives the transmission rod 1102 to rotate. The rotation of the transmission rod 1102 drives the rotating disk 1103 to rotate. The rotating disk 1103 drives the pressing rod 1104 to move backward. Under the guidance of the guide block 1002, the pressing rod 1104 causes the locking block 1003 to slide out from the limiting block 1001, realizing the separation between the locking block 1003 and the limiting block 1001. This forces the locking and limiting effect between the moving mold body 403 and the fixed mold body 2 to be released until the transverse buffer assembly 7 and the inclined buffer assembly 8 return to their original state. When the transverse buffer assembly 7 and the inclined buffer assembly 8 return to their original state, the moving mold body 403 continues to move upward, causing the load-bearing rod 904 to move upward and pull the connecting rod 902 to move. This causes the support block 901 to disengage from the top block 905, forcing the support block 901 to rotate around the hinge point. This forces the two connecting rods 902 to be in an upwardly extended state until the load-bearing rod 904 is at its maximum position at the ends of the two slides 903. As the moving mold body 403 continues to move upward, the load-bearing rod 904 generates an upward pulling force on the connecting rod 902, and the connecting rod 902 exerts a force on the support block 901, forcing the deflection rod 602 and the deflection rod 603 to continue to deflect inward. That is, the angle between the deflection rod 602 and the deflection rod 603 further decreases. When the lateral buffer assembly 7 and the tilting buffer assembly 8 move to their maximum reasonable limits, that is, the distance between the lateral buffer cylinder 701 and the first baffle 703 decreases to the minimum distance and the distance between the tilting buffer cylinder 801 and the second baffle 803 increases to the maximum distance, the pressure sensor 503 senses the upward lifting force and feeds it back to the control system. The control system automatically forces the hydraulic lifting rod 402 to stop moving, effectively preventing the phenomenon of excessive lifting force and avoiding the phenomenon of insufficient or excessive movement when the moving mold body 403 retracts. This ensures that energy consumption and production costs are reduced while removing the product. At this time, the position where the moving mold body 403 stops is the product removal height position. The operator uses tools to remove the product, completing one die-casting operation step.

[0032] This solution, on the one hand, can disperse the downward pressure force to the processing table 1 during mold closing, reducing the contact impact force between the moving mold body 403 and the fixed mold body 2, and achieving a buffering effect on the contact force, avoiding large wear during rapid contact and preventing molten metal from flowing out. At the same time, it can lock and limit the moving mold body 403 and the fixed mold body 2, reducing the lateral displacement of the moving mold body 403 during molten metal injection, preventing partial separation of the moving mold body 403 and the fixed mold body 2, and further preventing molten metal from flowing out. On the other hand, after die casting is completed, it can achieve precise control of the retraction of the moving mold body 403, avoiding insufficient or excessive movement, thereby reducing energy consumption and production costs, increasing the service life of the device, improving the control accuracy of the device, and enhancing automation stability.
