Since the beginning of the new era, with the continuous progress of science and technology, casting technology has also shown many new development trends and statuses, moving towards automation and intelligence, making the casting process more precise and efficient, while also reducing labor costs.

[0003] Existing casting technology requires clamping the mold, then pouring the required molten material into the mold for pressing, and waiting for it to cool before demolding. However, after cooling, the molded parts inside the mold will stick tightly to the inner wall of the mold cavity due to the previous high temperature, making it difficult for workers to demold them. This greatly reduces demolding efficiency and also increases the damage rate of parts. Summary of the Invention

[0004] The purpose of this invention is to address the following shortcomings in the existing technology: Existing casting technology requires clamping the mold, then pouring the required molten material into the mold for pressing, and waiting for it to cool before demolding. However, after cooling, the molded parts inside the mold will adhere tightly to the inner wall of the mold cavity due to the previous high temperature, making it difficult for workers to demold them. This greatly reduces demolding efficiency and also increases the damage rate of parts. Therefore, this invention proposes a casting mold for automotive bracket castings.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A casting mold for automobile bracket castings includes a housing and two mold plates, both of which are slidably connected to the housing.

[0007] A vibration device is installed inside the housing. The vibration device includes a threaded rod, a movable plate, a vibrating plate, and a striking pin. The threaded rod is rotatably connected inside the housing. A second gear is fixedly connected to one end of the threaded rod. The movable plate is threadedly connected to the threaded rod. A cylinder is provided at one end of the movable plate. A striking pin plate is slidably connected to the end of the cylinder away from the movable plate. The striking pin is fixedly connected to the striking pin plate. A straight spring is provided between the striking pin plate and the movable plate. The vibrating plate is fixedly connected to one of the mold plates. Multiple arc-shaped blocks are provided on the surface of the vibrating plate. A limit rod is fixedly connected inside the housing. The movable plate is slidably connected to the limit rod.

[0008] Preferably, a fixing block is fixedly connected to one end of the box body, a lead screw is rotatably connected to the fixing block, connecting rods are hinged to both sides of the fixing block, and arc rods are rotatably connected to the two connecting rods. A pressure plate is hinged to the end of the arc rod away from the connecting rod, and the two pressure plates are fixedly connected to the mold plate. A straight plate is threaded to one end of the lead screw, and the two ends of the straight plate are hinged to the two arc rods respectively.

[0009] Preferably, a first gear is fixedly connected to the end of the lead screw away from the straight plate, and a sliding groove is provided at the end of the housing near the first gear. A rack plate is slidably connected in the sliding groove, one end of the rack plate is meshed with the first gear, and the rack plate is meshed with the second gear.

[0010] Preferably, a water inlet pipe is fixedly connected to one end of the housing, a disc is fixedly connected inside the water inlet pipe, the disc has a water outlet, a baffle is slidably connected to one end of the disc, a pull rod is fixedly connected to one end of the baffle, a return spring is fixedly connected between the end of the pull rod away from the baffle and the fixed block, and an impact block is fixedly connected to the rack plate.

[0011] Preferably, a water tank is fixedly connected to the upper surface of the housing, the water tank is connected to the water inlet pipe, and multiple nozzles are installed at the upper end of the water tank, the nozzles being connected to the water tank.

[0012] Preferably, a piston plate is slidably connected inside the water tank, and a push rod is fixedly connected to one end of the piston plate. The end of the push rod away from the piston plate is fixedly connected to the pressure plate.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. The movement of the threaded rod and the moving plate drives the impact pin to continuously strike the vibrating plate, causing the mold plate to vibrate continuously. The vibration is transmitted to the inner cavity of the mold plate, which can separate the car bracket from the inner cavity of the mold plate, making demolding simpler.

[0015] 2. The straight plate is moved by the lead screw, which in turn causes the connecting rod and the arc rod to rotate, so that the two pressure plates press the two mold plates together.

[0016] 3. Water is injected into the water tank through the water inlet pipe. The pressure plate moves, which drives the push rod to move. The push rod pushes the piston plate to squeeze the water in the water tank into the nozzle. The nozzle sprays the water onto the surface of the two mold plates, which has a cooling effect. At the same time, due to the different thermal expansion and contraction properties of different metals, the thermal expansion and contraction can promote the separation of the car frame and the mold cavity.

A straight spring is provided between the striking pin plate 16 and the movable plate 14. The straight spring has a strong elastic force. The vibration plate 15 is fixedly connected to one of the mold plates 2. The surface of the vibration plate 15 is provided with multiple arc-shaped blocks. The size of the arc of the arc blocks can ensure that the striking pin 17 can pass smoothly. A limit rod 13 is fixedly connected inside the housing 1. The movable plate 14 is slidably connected to the limit rod 13. The main function of the limit rod 13 is to ensure that the movable plate 14 does not rotate.

[0026] A fixing block 4 is fixedly connected to one end of the housing 1. A lead screw 3 is rotatably connected to the fixing block 4. Connecting rods 5 are hinged to both sides of the fixing block 4. Arc rods 7 are rotatably connected to the two connecting rods 5. A pressure plate 8 is hinged to the end of the arc rod 7 away from the connecting rod 5. The two pressure plates 8 are fixedly connected to the mold plate 2. A straight plate 6 is threaded to one end of the lead screw 3. The two ends of the straight plate 6 are hinged to the two arc rods 7. A first gear 9 is fixedly connected to the end of the lead screw 3 away from the straight plate 6. The first gear 9 has a large tooth pitch. A sliding groove is provided at the end of the housing 1 near the first gear 9. A rack plate 10 is slidably connected in the sliding groove. One end of the rack plate 10 is meshed with the first gear 9. The rack plate 10 is meshed with the second gear 11. A water inlet pipe 23 is fixedly connected to one end of the housing 1. A disc 21 is fixedly connected in the water inlet pipe 23. The disc 21 has a water inlet. A baffle is slidably connected to one end of the disc 21. Plate 22, one end of baffle 22 is fixedly connected to a pull rod 20, the pull rod 20 and the water inlet pipe 23 are sealed to prevent water leakage, the end of pull rod 20 away from baffle 22 is fixedly connected to fixed block 4 with a return spring 19, the end of pull rod 20 near return spring 19 is set as a semi-circular block, the return spring 19 can reset pull rod 20 in a very short time, impact block 18 is fixedly connected to rack plate 10, the upper end of impact block 18 is set with a semi-circular block, the upper surface of box 1 is fixedly connected to water tank 24, water tank 24 is connected to water inlet pipe 23, multiple nozzles 27 are installed on the upper end of water tank 24, the nozzles 27 are connected to water tank 24, piston plate 26 is slidably connected inside water tank 24, piston plate 26 is sealed with the inner wall of water tank 24, one end of piston plate 26 is fixedly connected to push rod 25, push rod 25 is L-shaped, the end of push rod 25 away from piston plate 26 is fixedly connected to pressure plate 8.

[0027] In this utility model, the lead screw 3 is connected to an external servo motor. When the servo motor rotates in the forward direction, it drives the lead screw 3 to rotate. The lead screw 3 drives the straight plate 6 to move horizontally. The straight plate 6 drives the two arc rods 7 to rotate. The two arc rods 7 drive the pressure plate 8 to move respectively. The two pressure plates 8 push the mold plate 2 to move inward until the two mold plates are completely pressed together.

[0028] When the lead screw 3 rotates, it drives the rack plate 10 to move through the first gear 9, thereby impacting the block 18 and pushing the pull rod 20 to move. The horizontal movement of the pull rod 20 drives the baffle 22 to move. At this time, the water inlet hole on the disc 21 opens and injects water into the water tank.

[0029] After the molten material is formed, the servo motor rotates in the reverse direction. At this time, the pressure plate 8 begins to move the mold plate 2 outward. The first gear 9, which is sleeved on the lead screw 2, rotates and drives the second gear 11 to rotate through the rack plate 10 that meshes with it. The second gear drives the thread 12 to rotate. The rotation of the thread rod 12 drives the moving plate 14 to move horizontally. The impact pin 17 inside the cylinder is squeezed by the arc block on the vibrating plate 15 and extends and retracts into the cylinder. When the moving plate 10 leaves the arc block, the impact pin 17 inside the cylinder is pushed by the straight spring and hits the vibrating plate 15, causing the vibrating plate 15 to vibrate. This vibration is then transmitted to the inner cavity of the mold plate 2, facilitating the separation of the required parts from the inner wall of the mold cavity.

[0030] When the pressure plate 8 near the water tank 24 moves outward, the pressure plate 8 drives the push rod 25 to move. The push rod 25 pushes the piston plate 26 to move horizontally inside the water tank 24. The piston plate 26 squeezes the water in the water tank 24 into the nozzle 27. The water inside the nozzle 27 is under pressure and sprays the water onto the two mold plates 2, which has a cooling effect. At the same time, due to the different thermal expansion and contraction properties of different metals, the thermal expansion and contraction can promote the separation of the car frame and the mold cavity.

[0031] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

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