Description

Technical Field

[0001] This invention relates to the technical field of die casting, specifically to a die casting mold that automatically detaches castings. Background Technology

[0002] Die casting is a highly efficient and precise metal forming process. Its principle involves injecting molten liquid metal into a high-speed injection chamber, then rapidly filling a precision steel mold cavity under extremely high mechanical pressure, and finally cooling and solidifying under pressure to form a part of the desired shape.

[0003] According to Chinese patent announcement number CN223129314U, the invention includes a frame, a die-casting mold A, and a die-casting mold B. The frame is bolted to a cylinder A that provides power, and the power output end of cylinder A is fixed with a drive frame that drives the die-casting mold B to move. The die-casting mold B is provided with an injection port on its exterior to allow aluminum alloy casting material to enter the die-casting mold A and the die-casting mold B.

[0004] The above scheme uses two die-casting molds for casting, which still has the following disadvantages: when the two die-casting molds are separated, the finished product between the two die-casting molds may stick to the inner wall of the die-casting mold, requiring the machine to be stopped and manually assisted to demold, which reduces the working efficiency of die casting. Summary of the Invention

[0005] The purpose of this invention is to provide a die-casting mold that automatically releases castings, thereby solving the problem that finished products may adhere to the inner wall of the die-casting mold between two die-casting molds, requiring manual demolding assistance by stopping the machine, which reduces the efficiency of die casting.

[0006] To achieve the above-mentioned objectives, the present invention employs the following technical solution: a die-casting mold for automatic casting detachment, comprising a sliding plate, the sliding plate being slidably disposed on the top surface of a workbench, a mold body being detachably disposed on one side of the sliding plate, lower U-shaped plates being fixed to both sides of the workbench, a cylinder being hinged inside the lower U-shaped plate, upper U-shaped plates being fixed to both sides of the sliding plate, the telescopic rod of the cylinder being hinged to the upper U-shaped plate, an mounting plate being fixed to the top surface of the workbench, two sliding strips being disposed on the bottom surface of the sliding plate, an mounting groove being formed on the bottom surface of the sliding plate, an mounting strip being fixed to the top surface of the sliding strips, and the mounting strip being hinged inside the mounting groove.

[0007] Preferably, the top surface of the mounting plate has an injection groove, the top surface of the mounting plate is fixed with an injection pipe, the injection pipe is equipped with an automatic valve, the bottom surface of the injection groove has a sleeve hole, the bottom surface of the workbench is fixed with a hydraulic cylinder, the inside of the sleeve hole is fixed with a sealing ring, the inside of the injection groove is slidably arranged with a piston, the telescopic rod of the hydraulic cylinder passes through the workbench and is slidably inserted into the sleeve hole, the telescopic rod of the hydraulic cylinder is fixed with the bottom surface of the piston, and the inner wall of the injection groove has an injection hole.

[0008] Preferably, the top surface of the workbench has two sliding openings, and a long screw is rotatably installed inside the sliding opening, the long screw being threadedly connected to the sliding bar.

[0009] Preferably, a drive motor is fixed to the top surface of the workbench, a drive sprocket is fixed to the output shaft of the drive motor, two driven sprockets are rotatably arranged on one side of the workbench, one end of the long screw passes through the sliding port and is fixed to one side of the driven sprocket, and a transmission chain is arranged on one side of the workbench, the transmission chain meshing with the drive sprocket and the driven sprocket.

[0010] Preferably, threaded grooves are provided at all four corners on one side of the sliding plate, and rotating holes are provided at all four corners on one side of the mold body. Loading and unloading bolts are inserted into the rotating holes, and one end of the loading and unloading bolts passes through the rotating holes and is threadedly connected to the threaded grooves.

[0011] Preferably, a positioning hole is provided on one side of the sliding plate, an impact rod is slidably inserted into the positioning hole, a receiving groove is provided on the inner wall of the positioning hole, a fixing ring is fixedly sleeved on the impact rod, a return spring is wound around the surface of the impact rod, one end of the return spring is fixed to one side of the fixing ring, and the other end of the return spring is fixed to one side of the receiving groove.

[0012] Preferably, a servo motor is provided on one side of the sliding plate, and a rotating plate is fixed to one end of the output shaft of the servo motor, with the surface of the rotating plate in contact with one end of the impact rod.

[0013] Preferably, the top surface of the workbench has a drop-out opening, the bottom surface of the workbench has two supporting folding plates fixed, a collection frame is provided between the two supporting folding plates, the four corners of the bottom surface of the collection frame are respectively fixed with casters, and the bottom surface of the workbench is fixed with a positioning plate.

[0014] Compared with existing technologies, a die-casting mold that automatically releases castings using the above-mentioned technical solution has the following beneficial effects: 1. When the solidified product in the mold body is tilted by the extension rod of the cylinder, the solidified finished product in the mold body will naturally fall out of the mold body due to gravity, realizing automatic demolding of the finished product in the mold body, and no machine needs to be stopped during demolding, which increases the efficiency of die casting. 2. When the drive motor is working, the rotating output shaft will drive the drive sprocket to rotate synchronously. When the drive sprocket rotates, the transmission chain drives the two driven sprockets and the two long screws to rotate synchronously. When the long screws rotate, the threaded connection between the long screws and the sliding bar can be used to drive the sliding plate and the mold body to slide laterally on the top surface of the worktable, which makes it easier for the mold body to move closer to or away from the mounting plate. Third, depending on the style of the die-cast finished product, the staff can replace different mold bodies by disassembling and removing the bolts, which increases the applicability of processing products of different shapes. When the sliding plate is in an inclined state, the output shaft of the servo motor will drive the rotating plate to rotate synchronously, which can push the impact rod to move laterally repeatedly inside the positioning hole and impact the surface of the mold body, causing the mold body to vibrate, which can quickly separate the solidified finished product surface from the inner wall of the mold body. Fourth, finished products falling from the mold body will pass through the drop opening and fall into the inside of the collection box. The collection box is used to stack the finished products together, which makes it easier for staff to process a large number of finished products in one go. When the staff pushes the collection box between the two support folding plates, the positioning plate can prevent the collection box from moving further between the two support folding plates, which increases the convenience for the staff to process solidified finished products.

Detailed Implementation

[0023] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, a die-casting mold for automatic casting detachment includes a sliding plate 2, which is slidably disposed on the top surface of a workbench 1. A mold body 3 is detachably disposed on one side of the sliding plate 2. Lower U-shaped plates 4 are fixed to both sides of the workbench 1, and cylinders 5 are hinged inside the lower U-shaped plates 4. Upper U-shaped plates 6 are fixed to both sides of the sliding plate 2, and the extension rod of the cylinders 5 is hinged to the upper U-shaped plates 6. A mounting plate 7 is fixed to the top surface of the workbench 1. Two sliding strips 8 are disposed on the bottom surface of the sliding plate 2, and a mounting groove 9 is formed on the bottom surface of the sliding plate 2. A mounting strip 10 is fixed to the top surface of the sliding strips 8. The strip 10 is hinged inside the mounting groove 9. The top surface of the mounting plate 7 is provided with an injection groove 17. An injection pipe 18 is fixed on the top surface of the mounting plate 7. An automatic valve is provided on the injection pipe 18. The bottom surface of the injection groove 17 is provided with a sleeve hole 19. The bottom surface of the workbench 1 is fixed with a hydraulic cylinder 20. A sealing ring 21 is fixed inside the sleeve hole 19. A piston 22 is slidably arranged inside the injection groove 17. The telescopic rod of the hydraulic cylinder 20 passes through the workbench 1 and is slidably inserted into the sleeve hole 19. The telescopic rod of the hydraulic cylinder 20 is fixed with the bottom surface of the piston 22. An injection hole 23 is provided on the inner wall surface of the injection groove 17.

[0025] In use, the operator first pours molten metal into the injection tank 17 through the injection pipe 18. At this time, the sliding plate 2 and the mold body 3 are attached to one side of the mounting plate 7. Then, the hydraulic cylinder 20 pushes the piston 22 to slide upward inside the injection tank 17 using the rising telescopic rod. This allows the molten metal inside the injection tank 17 to be injected into the mold body 3 through the injection hole 23. The mold body 3 is then used for die casting. After die casting, the sliding plate 2 slides away from the mounting plate 7 on the top surface of the workbench 1. Then, the cylinder 5 pushes the sliding plate 2 and the mold body 3 to rotate around the sliding bar 8 using the extended telescopic rod. This causes the sliding plate 2 and the mold body 3 to be in an inclined state, which allows the solidified finished product in the mold body 3 to be automatically removed. When the solidified product in the mold body 3 is tilted by the extension rod of the cylinder 5, the solidified finished product in the mold body 3 will naturally fall out of the mold body 3 due to gravity, realizing automatic demolding of the finished product in the mold body 3, and no machine stop is required during demolding, which increases the efficiency of die casting.

[0026] like Figure 2 and Figure 3 As shown, the top surface of the workbench 1 has two sliding openings 11. A long screw 12 is rotatably installed inside the sliding opening 11. The long screw 12 is threadedly connected to the sliding bar 8. A drive motor 13 is fixed on the top surface of the workbench 1. The output shaft of the drive motor 13 is fixed with a drive sprocket 14. Two driven sprockets 15 are rotatably installed on one side of the workbench 1. One end of the long screw 12 passes through the sliding opening 11 and is fixed to one side of the driven sprocket 15. A transmission chain 16 is installed on one side of the workbench 1. The transmission chain 16 meshes with the drive sprocket 14 and the driven sprocket 15.

[0027] During use, the output shaft of the drive motor 13 rotates and drives the drive sprocket 14 to rotate synchronously. When the drive sprocket 14 rotates, the transmission chain 16 drives the two driven sprockets 15 and the two long screws 12 to rotate synchronously. When the long screws 12 rotate, the threaded connection between the long screws 12 and the sliding bar 8 can be used to drive the sliding plate 2 and the mold body 3 to slide laterally on the top surface of the workbench 1, so that the mold body 3 can move closer to or away from the mounting plate 7.

[0028] like Figure 6 and Figure 7As shown, threaded grooves 24 are provided at the four corners of one side of the sliding plate 2, and rotating holes 25 are provided at the four corners of one side of the mold body 3. A mounting bolt 26 is inserted into the rotating hole 25. One end of the mounting bolt 26 passes through the rotating hole 25 and is threadedly connected to the threaded groove 24. A positioning hole 27 is provided on one side of the sliding plate 2. An impact rod 28 is slidably inserted into the positioning hole 27. A receiving groove 29 is provided on the inner wall of the positioning hole 27. A fixing ring 30 is fixedly sleeved on the impact rod 28. A return spring 31 is wound around the surface of the impact rod 28. One end of the return spring 31 is fixed to one side of the fixing ring 30, and the other end of the return spring 31 is fixed to one side of the receiving groove 29. A servo motor 32 is provided on one side of the sliding plate 2. A rotating plate 33 is fixed to one end of the output shaft of the servo motor 32. The surface of the rotating plate 33 is in contact with one end of the impact rod 28.

[0029] During use, depending on the style of the die-cast finished product, the operator can replace different mold bodies 3 by disassembling and removing bolts 26, which increases the applicability of processing products of different shapes. When the sliding plate 2 is in an inclined state, the output shaft of the servo motor 32 will drive the rotating plate 33 to rotate synchronously, which can push the impact rod 28 to move laterally repeatedly inside the positioning hole 27 and impact the surface of the mold body 3, causing the mold body 3 to vibrate, which can quickly separate the solidified finished product surface from the inner wall of the mold body 3.

[0030] like Figure 2 and Figure 4 As shown, the top surface of the workbench 1 is provided with a drop hole 34, the bottom surface of the workbench 1 is fixed with two support plates 35, a collection frame 36 is provided between the two support plates 35, the four corners of the bottom surface of the collection frame 36 are respectively fixed with casters 37, and the bottom surface of the workbench 1 is fixed with a positioning plate 38.

[0031] During use, finished products falling from the mold body 3 will pass through the drop opening 34 and fall into the inside of the collection frame 36. The collection frame 36 is used to stack the finished products together, which makes it easier for staff to process a large number of finished products in one go. When the staff pushes the collection frame 36 between the two support folding plates 35, the positioning plate 38 can prevent the collection frame 36 from moving further between the two support folding plates 35, which increases the convenience for the staff to process solidified finished products.

[0032] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
