Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, specifically a combined die-casting mold for automotive hardware parts. Background Technology

[0002] Die casting molds are tools used to cast automotive metal parts, specifically for completing the die casting process on a specialized die casting and forging machine. The basic die casting process involves molten metal being poured into the mold cavity at low or high speed. The mold has movable cavity surfaces, which are pressurized and forged as the molten metal cools. This process eliminates shrinkage cavities and porosity defects in the blank, and also allows the internal structure of the blank to achieve a forged, fragmented grain structure, significantly improving the overall mechanical properties of the blank.

[0003] A search revealed a combined die-casting mold with authorized patent publication number CN218611619U, comprising an upper connecting plate. Two vertical plates are symmetrically fixedly connected to the bottom of the upper connecting plate, and two electric push rods are symmetrically fixedly connected to the top of the upper connecting plate. The output ends of both electric push rods extend below the upper connecting plate. An upper mold cover plate is fixedly connected between the bottom of the output ends of the two electric push rods. A lower fixing box is fixedly connected between the two vertical plates, and a lower mold cover plate is fixedly connected to the top of the lower fixing box. A lower connecting plate is slidably connected inside the lower fixing box. This utility model, through the above-mentioned design, solves the problem that a structure for removing the workpiece needs to be set inside the die-casting mold, which not only wastes raw materials but also increases processing steps and working time.

[0004] However, this die-casting mold has the following shortcomings. When using this combined die-casting mold, the upper mold cover plate drives the ejector rod to move and demold the die-casting part in the lower mold cover plate. However, since the die-casting part in the lower mold cover plate is difficult to remove after die-casting, forcibly ejecting it can easily damage it and affect the product qualification rate.

[0005] Therefore, a solution is proposed. Summary of the Invention

[0012] Preferably, an electric telescopic rod is installed on the top of the support frame, and the electric telescopic rod passes through the top of the support frame and is fixedly connected to the upper mold.

[0013] Preferably, it also includes two synchronous pulleys, which are connected by a belt. One of the synchronous pulleys is fixedly connected to the other output end of the dual-axis servo motor, and the other output end is fixedly connected to one end of the rotating shaft.

[0017] This invention provides a combined die-casting mold for automotive hardware parts. It has the following advantages:

[0018] 1. The present invention uses a combined die-casting mold, through the coordinated use of components such as a first bevel gear, a second bevel gear, a bidirectional screw, and a threaded seat, to drive the two lower molds to close quickly, forming a closed area to match the upper mold for die-casting processing.

[0019] 2. By adding an ejector assembly, the present invention can squeeze the moving rod through the set movable block, thereby driving the ejector rod to rise and fall, thus realizing the linkage between the ejector rod and the upper mold. This facilitates the ejection of the die-casting part when the two lower molds separate and the upper mold rises, achieving a rapid demolding effect.

[0020] 3. This invention, through the coordinated use of structural components such as a movable plate, a fixed block, a traction rod, a support column, a rubber piston, and a drain pipe, allows for the metered spraying of molten metal into the mold. This metered spraying ensures uniform distribution of the molten metal within the mold, preventing overfilling or incomplete filling in localized areas and ensuring the accuracy of the casting's shape and dimensions. Simultaneously, metered spraying allows for better control of the molten metal's flow, reducing the generation of gas and inclusions, thereby lowering the probability of defects such as porosity and shrinkage cavities in the casting and improving its density and mechanical properties.

[0030] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see the appendix Figure 1 - Appendix Figure 8This invention provides a combined die-casting mold for automotive hardware, including a mounting base plate 1. A base 11 is mounted on the top of the mounting base plate 1. A dual-axis servo motor 701 is fixedly connected to the outside of the base 11. A transmission rod 702 is fixedly connected to the output end of the dual-axis servo motor 701. Two second bevel gears 704 are fixedly connected to the outside of the transmission rod 702. Two grooves are formed on the outer surface of the base 11. A bidirectional screw 705 is rotatably connected inside the grooves. A first bevel gear 703 is fixedly connected to one end of the bidirectional screw 705. Two threaded seats 706 are threadedly connected to the outside of the bidirectional screw 705. A lower mold 12 is fixedly connected to the top of the threaded seats 706. The dual-axis servo motor 701 drives the two bidirectional screws 705 to rotate. With the mutual approach and movement of the two threaded seats 706, the two lower molds 12 are opened, closed, and separated. An ejection assembly is installed on the inner side of the base 11. The ejection assembly is used to eject the hardware parts from the forming cavity inside the lower mold 12.

[0032] Specifically, by starting the other output end of the dual-axis servo motor 701, the transmission rod 702 is driven to rotate, which in turn drives the two second bevel gears 704 to rotate, causing the two meshing first bevel gears 703 to rotate synchronously, so that the bidirectional screw 705 rotates, and the two threaded seats 706 move away from each other along the outer wall of the bidirectional screw 705, so that the two lower molds 12 move away from each other, making demolding easier and preventing wear on the die-casting parts, resulting in a higher die-casting part qualification rate.

[0033] The ejection assembly includes a drive screw 1007 rotatably connected to the inner wall of the mounting housing 3. A drive gear 1009 is fixedly connected to the outer side of the drive screw 1007. A threaded bracket 1008 is threadedly connected to the outer side of the drive screw 1007. A movable block 1003 is fixedly connected to one end of the threaded bracket 1008. A movable groove 1004 is opened inside the movable block 1003. A moving rod 1006 is slidably connected to a through hole on one side of the top of the mounting housing 3. A connecting block 1005 is fixedly connected to the outer side of the moving rod 1006. A top rod 1001 is fixedly connected to the top of the moving rod 1006. A rack plate 1002 is slidably connected to a through hole on the other side of the top of the mounting housing 3. The outer side of the rack plate 1002 meshes with the outer side of the drive gear 1009.

[0034] Specifically, the output end of the electric telescopic rod 5 retracts, which causes the rack plate 1002 connected to the upper mold 13 to move upward. Since the rack plate 1002 and the upper mold 13 are fixedly connected, the rack plate 1002 can synchronously move the upper mold 13 upward during its movement. The rack plate 1002 meshes with the drive gear 1009. When the rack plate 1002 rises, it pushes the drive gear 1009 to rotate, and the rotation of the drive gear 1009 is further transmitted to the drive screw 1007, causing it to rotate coaxially. The rotation of the drive screw 1007 causes the threaded bracket 1008 to move to the left along the outer wall of the drive screw 1007 in a helical direction. This process is achieved through a threaded connection; during the leftward movement of the threaded bracket 1008, the movable block 1003 also moves synchronously. The movable groove 1004 within the movable block 1003 allows the connecting block 1005 to slide along with the movement of the movable block 1003. Driven by the connecting block 1005, the moving rod 1006 also moves synchronously, thereby pushing the ejector rod 1001 upward. The upward movement of the ejector rod 1001 will push the workpiece in the lower mold 12 upward, thus completing the ejection operation.

[0035] A support frame 2 is fixedly connected to the top rear side of the mounting base plate 1. A metering box 401 is fixedly connected to the top of the support frame 2. A rotating shaft is movably mounted on the outer through-hole bearing of the metering box 401. A rotating disk 403 is fixedly connected to one end of the rotating shaft. A fixing block 405 is fixedly connected to the outer eccentric part of the rotating disk 403. A movable plate 404 is slidably connected inside the metering box 401. A traction rod 406 is fixedly connected to the outer side of the movable plate 404. A rubber piston 408 is fixedly connected to one end of the traction rod 406. An installation cavity 402 is opened on one side of the inside of the metering box 401. A drain pipe 409 is connected to the bottom through-hole of the metering box 401. A control valve is installed on the outside of the drain pipe 409. A support column 407 is slidably mounted on the outer side of the traction rod 406. Both the upper and lower ends of the support column 407 are fixedly connected to the inner side of the metering box 401.

[0036] Specifically, the mounting base 1 supports the entire device. A rotating shaft is movably mounted on the outer through-hole of the metering tank 401 via a bearing, with one end of the rotating shaft fixedly connected to the rotating disk 403. A fixing block 405 is fixedly connected to the eccentric part of the outer side of the rotating disk 403. This fixing block 405, through its cooperation with the movable plate 404 inside the metering tank 401, achieves the metered discharge of molten metal. The movable plate 404 inside the metering tank 401 is tightly fitted with the sliding connection structure inside the metering tank 401, ensuring that the movable plate 404 can move effectively during liquid discharge. A traction rod 406 is fixedly connected to the outer side of the movable plate 404, with a rubber piston 408 fixedly connected to one end of the traction rod 406. The rubber piston 408 is in close contact with the inner wall of the metering tank 401 and can slide inside the tank to control the liquid discharge. The bottom through-hole of the metering tank 401 is connected to an external system via a drain pipe 409, and a control valve is installed on the outside of the drain pipe 409. By controlling the opening and closing of the valve, the flow rate and discharge speed of the molten metal can be precisely adjusted.

[0037] The dual-axis servo motor 701 is started, which drives the rotating shaft to rotate via a synchronous pulley and belt. The rotation of the rotating shaft causes the rotating disk 403 to rotate eccentrically, causing the fixed block 405 to rotate eccentrically along the outer surface of the rotating disk 403, which in turn drives the movable plate 404 and the traction rod 406 to reciprocate horizontally. The left and right movement of the traction rod 406 causes the rubber piston 408 to slide on the inner wall of the mounting cavity 402.

[0038] Each movement of the rubber piston 408 pushes the molten metal in the metering tank 401 through the drain pipe 409 for precise discharge. Since the length of the traction rod 406 is fixed, each reciprocating motion of the movable plate 404 discharges a fixed amount of molten metal, thus achieving metered injection of the molten metal. The precision and consistency of this device make it ideal for casting or molding processes requiring precise injection. This device achieves metered discharge of molten metal through the reciprocating motion of the rubber piston 408 combined with the eccentric motion of the rotating disk 403. The discharge volume is fixed each time, and the discharge volume can be precisely controlled by adjusting the initial position. This metered control method is more accurate and reliable than traditional manual operation.

[0039] A mounting base 601 is fixedly connected to the top of the metering tank 401. The bottom of the mounting base 601 is sequentially connected to a second through hole 604 and a first through hole 602. A baffle plate 605 is connected inside the mounting base 601 via a tension spring 606. A liquid inlet pipe 603 is connected to one side of the top of the mounting base 601. An electric telescopic rod 5 is installed on the top of the support frame 2. The electric telescopic rod 5 passes through the top of the support frame 2 and is fixedly connected to the upper mold 13. A groove is formed inside the movable plate 404, and a fixing block 405 is movably connected inside the groove.

[0040] Specifically, during the operation of this quantitative molten metal injection device, molten metal enters the mounting base 601 through the inlet pipe 603 via external equipment. The mounting base 601 is connected to the metering tank 401 through the second through hole 604 and the first through hole 602. When the molten metal enters and fills the mounting cavity 402, the liquid pressure pushes the baffle plate 605 inside the mounting base 601 forward, and the baffle plate 605 eventually blocks the discharge port of the inlet pipe 603, preventing the molten metal from continuing to flow in.

[0041] It also includes two synchronous pulleys connected by a belt. One synchronous pulley is fixedly connected to the other output end of the dual-axis servo motor 701, and the other output end is fixedly connected to one end of the rotating shaft. The outer sides of the two first bevel gears 703 are respectively meshed with the outer sides of the corresponding second bevel gears 704. The end of the transmission rod 702 away from the dual-axis servo motor 701 is rotatably connected to the inner wall of the base 11.

[0042] Specifically, by starting the dual-axis servo motor 701, one of the synchronous pulleys is driven to rotate. This synchronous pulley drives the other synchronous pulley to rotate through the belt drive, which in turn drives the rotating shaft to rotate, thus enabling the metering component to work.

[0043] One of the lower molds 12 has a sealing groove 9 on one side, and the other lower mold 12 has a sealing rod 8 fixedly connected to one side, with the sealing rod 8 matching the sealing groove 9.

[0044] Specifically, when the two lower molds 12 come close to each other, their sealing rods 8 will be inserted into the sealing grooves 9 to ensure the stability of the connection process between the two lower molds 12.

[0045] Working Principle: In practical use, the electric telescopic rod 5 is activated, causing the upper mold 13 to move downwards, closing the upper mold 13 with the lower mold 12. At this time, molten metal is pumped through the inlet pipe 603 into the mounting base 601 via an external device such as a pump. The liquid inside the mounting base 601 enters the mounting cavity 402 through the second through hole 604. Once the mounting cavity 402 is full, the molten metal pushes the baffle plate 605 through the first through hole 602 until the baffle plate 605 blocks the discharge port of the inlet pipe 603. Then, the dual-axis servo motor 701, in conjunction with the synchronous pulley and belt, drives the rotating shaft to rotate, further causing the rotating disk 403 to rotate coaxially, allowing the fixed block 405 to rotate along the rotating shaft. The outer surface of the disc 403 rotates eccentrically, which drives the movable plate 404 and the traction rod 406 to reciprocate left and right, causing the rubber piston 408 to move along the inner wall of the mounting cavity 402. This allows the molten metal inside the mounting cavity 402 to be discharged into the mold through the drain pipe 409. Since the length of the traction rod 406 is fixed, the amount of molten metal discharged each time is fixed, achieving the technical effect of quantitative molten metal injection. Subsequently, only the initial position of the rubber piston 408 needs to be changed to control the adjustment of the amount of molten metal. In addition, when the rubber piston 408 retracts, the tension spring 606 resets and drives the baffle plate 605 to move, so that the outlet of the inlet pipe 603 is no longer blocked, and molten metal can continue to be injected into the quantitative tank 401, preparing for the next molding of automotive hardware parts.

[0046] After the molten metal inside the mold cools down, an automotive hardware part is formed. At this time, the other output end of the dual-axis servo motor 701 is activated to drive the transmission rod 702 to rotate, which in turn drives the two second bevel gears 704 to rotate, causing the two meshing first bevel gears 703 to rotate synchronously. This causes the bidirectional screw 705 to rotate, and the two threaded seats 706 move away from each other along the outer wall of the bidirectional screw 705, thus moving the two lower molds 12 away from each other. This facilitates demolding, prevents wear on the die-cast parts, and results in a higher yield rate for the die-cast parts. At the same time, the output end of the electric telescopic rod 5 retracts, causing the upper mold 13 to move upward. Due to the rack... Plate 1002 is connected to upper mold 13, so when upper mold 13 moves, it can drive rack plate 1002 to move synchronously, thereby driving drive gear 1009 to rotate synchronously, further causing drive screw 1007 to rotate coaxially, moving thread frame 1008 to the left along the outer wall of drive screw 1007. When thread frame 1008 moves, it drives movable block 1003 to move synchronously. At this time, connecting block 1005 moves along the inner wall of movable groove 1004, thereby driving moving rod 1006 and ejector rod 1001 to move upward, pushing the workpiece inside lower mold 12 upward without manual ejection, greatly improving the ease of use of the device.
