Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of case shell processing, especially to a case shell high-pressure die casting forming device. BACKGROUND

[0002] At present, most of the case shells are formed through high-pressure die casting in the production process, and the die casting is a metal casting process, which is characterized by applying high pressure to molten metal in the cavity of a mold, and the mold is usually made of an alloy with higher strength, and this process is somewhat similar to injection molding.

[0003] In the related art, the die casting forming device includes a fixed mold and a movable mold, and the movable mold is provided with a liquid injection system. During production, the movable mold and the fixed mold are attached to each other, and the liquid injection system is used to inject high-temperature metal liquid into the forming cavity between the fixed mold and the movable mold. After the liquid in the forming cavity cools down, the shell is formed. However, during demolding, the formed shell is usually manually removed from the mold using tools, which requires a lot of labor and time, affecting the processing efficiency, and thus needs to be improved. SUMMARY

[0004] In order to automatically remove the formed shell from the mold, reduce manual labor, and improve production efficiency, the present application provides a case shell high-pressure die casting forming device.

[0005] The case shell high-pressure die casting forming device provided by the present application adopts the following technical scheme:

[0006] The case shell high-pressure die casting forming device comprises a rack and a mold arranged on the rack. The mold comprises a movable mold and a fixed mold. The movable mold is movably arranged on the rack, and the fixed mold is fixedly arranged on the rack. The side of the fixed mold facing the movable mold is provided with a forming groove. A plurality of abutting grooves are formed in the bottom wall of the forming groove, and an abutting disc adapted to the abutting grooves is arranged in the abutting grooves. A group of guide rods are symmetrically arranged on the side wall of the abutting disc. A guide groove is formed in the bottom wall of the abutting groove, and the guide rods are slidably arranged in the guide groove. A reset disc is arranged at the end of the guide rod away from the abutting disc. A reset spring is sleeved on the guide rod, one end of the reset spring abuts against the side wall of the fixed mold, and the other end of the reset spring abuts against the reset disc. An abutting hole is formed in the bottom wall of the abutting groove, and an abutting rod is slidably arranged in the abutting hole. The abutting rod can abut against the abutting disc. The abutting rod is connected with a connecting rod, and the connecting rod is connected with the fixed mold.

[0007] By adopting the above technical scheme, when the outer shell is pressure die formed, the movable mold moves towards the fixed mold until they are attached to each other, and the movable mold moves while driving the abutting rod to slide in the abutting hole away from the abutting disc through the connecting rod, at this time, the forming groove is sealed, the reset spring is abutted with the reset disc, driving the abutting disc in the abutting groove, the abutting disc seals the abutting groove while the surface of the abutting disc is flush with the bottom wall of the forming groove; after pressure die forming, the movable mold slides away from the fixed mold, at this time, the connecting rod drives the abutting rod to approach the abutting disc, the abutting rod can abut with the abutting disc, and the guide rod slides in the guide groove to guide the abutting disc, so that the abutting disc can abut with the outer shell formed in the forming groove, and the outer shell in the forming groove can fall off from the forming groove under the action of the abutting disc, realizing automatic separation, the abutting rod is driven to move by the connecting rod when the fixed mold moves, and the formed outer shell is automatically separated from the mold, reducing manual labor and improving production and processing efficiency.

[0008] Preferably, a side wall of the abutting disc is fixedly provided with a sealing ring, a bottom wall of the abutting groove is provided with a sealing groove for inserting the sealing ring, and the sealing ring and the sealing groove are matched with each other.

[0009] By adopting the above technical scheme, after the abutting rod moves away from the abutting disc, the reset spring abuts with the reset disc, driving the abutting disc to reset to the abutting groove, when the abutting disc is inserted into the abutting groove, the sealing ring can be inserted into the sealing groove, and the sealing ring and the sealing groove are matched with each other to improve the sealing between the abutting disc and the abutting groove, thereby ensuring the quality of the outer shell formed in the forming groove.

[0010] Preferably, an end wall of the sealing ring is in a circular arc shape, and one end of the abutting disc towards the abutting groove direction is provided with a guide surface.

[0011] By adopting the above technical scheme, the circular arc-shaped sealing ring is convenient to insert into the sealing groove, and the guide surface can guide the abutting disc, so that the abutting disc is conveniently inserted into the abutting groove during resetting.

[0012] Preferably, the reset disc is provided with a mounting groove for inserting the guide rod, and the guide rod and the mounting groove are threadedly connected.

[0013] By adopting the above technical scheme, the guide rod and the mounting groove are threadedly connected, the reset disc and the guide rod are disassembled, and the reset spring is conveniently maintained and replaced.

[0014] Preferably, a material collecting groove is arranged between the racks, a material collecting frame is arranged in the material collecting groove, rotating shafts are symmetrically arranged at both ends of the material collecting frame and are rotationally connected between the inner wall of the material collecting groove, a material collecting belt is drivingly arranged in the material collecting groove below the material collecting frame, and a rotating assembly is arranged between the racks and the material collecting frame, and the rotating assembly is used to drive the material collecting frame to rotate relative to the inner wall of the material collecting groove.

[0015] By adopting the above technical solution, during demolding, the abutting rod abuts against the abutting plate, which in turn abuts against the shell formed in the forming groove. After the shell falls off, it can fall into the receiving rack. Then, the rotating component drives the receiving rack to rotate between itself and the inner wall of the receiving groove, causing the receiving rack to flip. Under the action of gravity, the shell may fall onto the receiving belt. The driven receiving belt automatically sends the formed shell into the next processing and forming process, thereby further improving the automation level of receiving.

[0016] Preferably, the rotating assembly includes a cylinder, a rack, and a gear. The cylinder is mounted on a frame, and the piston rod of the cylinder is connected to the rack. The gear is mounted on a rotating shaft, and the gear meshes with the rack.

[0017] By adopting the above technical solution, after the outer shell falls into the receiving rack, the piston rod of the cylinder extends and retracts, causing the rack to slide. The rack and gear collide, thereby driving the rotating shaft and the receiving rack to rotate, making the control convenient and quick.

[0018] Preferably, the receiving rack is provided with cushioning cotton.

[0019] By adopting the above technical solution, when the outer shell falls from the forming tank into the receiving rack, the cushioning cotton cushions the outer shell, reducing the possibility of damage to the outer shell.

[0020] Preferably, a rubber block is provided at the end of the abutment rod facing the abutment plate.

[0021] By adopting the above technical solution, when the moving mold drives the abutting rod to abut against the abutting plate, the rubber block can play a buffering and protective role upon contact.

[0022] In summary, this application includes at least one of the following beneficial technical effects:

[0023] 1. By setting up a frame, moving mold, fixed mold, forming groove, abutment groove, abutment plate, guide rod and guide groove, reset plate, reset spring, abutment hole, abutment rod and connecting rod, after die casting, the moving mold slides away from the fixed mold. At this time, the connecting rod drives the abutment rod to abut against the abutment plate. The guide rod slides in the guide groove to guide the abutment plate, so that the abutment plate can abut against the shell formed in the forming groove. Under the action of the abutment plate, the shell in the forming groove can be detached from the forming groove, realizing automatic detachment. When the fixed mold moves, the connecting rod drives the abutment rod to move, automatically removing the formed shell from the mold, reducing manual labor and improving production efficiency.

[0024] 2. By setting a sealing ring and a sealing groove, after the abutting rod moves away from the abutting plate, the return spring abuts against the return plate, driving the abutting plate to return to the abutting groove. When the abutting plate is inserted into the abutting groove, the sealing ring can be inserted into the sealing groove. The cooperation between the sealing ring and the sealing groove can improve the sealing between the abutting plate and the abutting groove, thereby ensuring the quality of the inner and outer shell after molding.

[0025] 3. By setting up a receiving trough, receiving rack, rotating shaft, receiving belt, and rotating assembly, during demolding, the abutment rod abuts against the abutment plate, causing the abutment plate to abut against the shell formed in the forming groove. After the shell falls off, it can fall into the receiving rack. Then, the rotating assembly drives the receiving rack to rotate between itself and the inner wall of the receiving trough, causing the receiving rack to flip. Under the action of gravity, the shell may fall onto the receiving belt. The driven receiving belt automatically sends the formed shell into the next processing stage, thereby further improving the automation level of receiving. Attached Figure Description

[0029] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0030] This application discloses a high-pressure die-casting apparatus for chassis housings. (Refer to...) Figure 1 and Figure 2 The device includes a frame 1 and a mold mounted on the frame 1. The mold includes a movable mold 21 and a fixed mold 22, both of which are arranged vertically. The movable mold 21 is movably mounted on the frame 1, and the fixed mold 22 is fixedly mounted on the frame 1. A forming groove 3 is provided on the side of the fixed mold 22 facing the movable mold 21. Several abutment grooves 31 are formed on the bottom wall of the forming groove 3. In this embodiment, two abutment grooves 31 are symmetrically arranged. A matching abutment plate 32 is provided in the abutment groove 31, and the surface of the abutment plate 32 is flush with the bottom wall of the forming groove 3.

[0031] Reference Figure 1 and Figure 2 A set of guide rods 4 are symmetrically arranged on the side wall of the abutment plate 32. The length direction of the guide rods 4 is horizontal. A guide groove 41 is provided through the bottom wall of the abutment groove 31. The guide rods 4 are slidably arranged in the guide groove 41 and are mutually adapted. A reset plate 5 is provided at the end of the guide rod 4 away from the abutment plate 32. A reset spring 51 is sleeved on the guide rod 4. One end of the reset spring 51 abuts against the side wall of the fixed mold 22, and the other end of the reset spring 51 abuts against the reset plate 5. An abutment hole 6 is provided through the bottom wall of the abutment groove 31. The abutment hole 6 is arranged along the length direction of the guide rod 4. An abutment rod 61 is slidably arranged through the abutment hole 6. The abutment rod 61 is connected to a connecting rod 62. The connecting rod 62 is bent and fixedly connected to the fixed mold 22.

[0032] Reference Figure 1 and Figure 2 A rubber block 10 is provided at one end of the abutment rod 61 facing the abutment plate 32. During the die-casting of the outer shell, the moving mold 21 moves closer to the fixed mold 22 until they are in contact. As the moving mold 21 moves, the connecting rod 62 drives the abutment rod 61 to slide away from the abutment plate 32 in the abutment hole 6. At this time, the return spring 51 abuts against the return plate 5, restricting the abutment plate 32 in the abutment groove 31, and the forming groove 3 is sealed. After the die-casting is completed, the moving mold 21 slides away from the fixed mold 22. At this time, the connecting rod 62 drives several abutment rods 61 to approach the abutment plate 32 at the same time. The abutment rod 61 can drive the rubber block 10 to abut against the abutment plate 32. The guide rod 4 slides in the guide groove 41 to guide the abutment plate 32, so that the abutment plate 32 can abut against the outer shell formed in the forming groove 3. Under the action of the abutment plate 32, the outer shell in the forming groove 3 can be detached from the forming groove 3, realizing automatic demolding. The connecting rod 62 drives the abutment rod 61 to move when the fixed mold 22 moves, eliminating the need for a separate drive component to control the sliding of the abutment rod 61, thus saving on device costs.

[0033] Reference Figure 2 A sealing ring 7 is integrally fixed to the side wall of the abutment plate 32. The sealing ring 7 is arranged along the circumference of the abutment plate 32. A sealing groove 71 for inserting the sealing ring 7 is opened on the bottom wall of the abutment groove 31. The sealing ring 7 and the sealing groove 71 are mutually adapted. The end wall of the sealing ring 7 is arc-shaped. A guide surface 72 is provided at the end of the abutment plate 32 facing the abutment groove 31. After the abutment rod 61 moves away from the abutment plate 32, the return spring 51 abuts against the return plate 5. The guide surface 72 guides and drives the abutment plate 32 to return to the abutment groove 31. When the abutment plate 32 is inserted into the abutment groove 31, the sealing ring 7 can be inserted into the sealing groove 71. The cooperation between the sealing ring 7 and the sealing groove 71 can improve the sealing between the abutment plate 32 and the abutment groove 31, thereby ensuring the quality of the inner and outer shells of the molding groove 3 after molding.

[0034] Reference Figure 2 The reset plate 5 has an installation groove 52 for inserting the guide rod 4. The guide rod 4 is threadedly connected to the inner wall of the installation groove 52, which enables the reset plate 5 and the guide rod 4 to be disassembled and assembled, and facilitates the maintenance and replacement of the reset spring 51.

[0035] Reference Figure 1 A receiving trough 11 is provided between the frame 1 and the moving mold 21. The receiving trough 11 is located between the fixed mold 22 and the moving mold 21. A receiving rack 8 is provided inside the receiving trough 11, and a cushioning cotton 82 is provided on the receiving rack 8. Rotating shafts 81 are symmetrically arranged at both ends of the receiving rack 8. The rotating shafts 81 are rotatably connected to the inner wall of the receiving trough 11. A receiving belt 12 is driven inside the receiving trough 11 and below the receiving rack 8. A rotating assembly is provided between the frame 1 and the receiving rack 8. The rotating assembly includes a cylinder 91, a rack 92 and a gear 93. The cylinder 91 is fixedly mounted on the frame 1 by bolts. The piston rod of the cylinder 91 is connected to the rack 92. The gear 93 is mounted on the rotating shaft 81, and the gear 93 meshes with the rack 92. During demolding, the abutting rod 61 abuts against the abutting plate 32, causing the abutting plate 32 to abut against the shell formed in the forming groove 3. After the shell falls off, it can fall into the receiving rack 8. Then, the cylinder 91 works, causing the rack 92 to abut against the gear 93, which in turn drives the rotating shaft 81 and the receiving rack 8 to rotate, causing the receiving rack 8 to flip. Under the action of gravity, the shell may fall onto the receiving belt 12. The receiving belt 12 automatically sends the formed shell to the next processing stage, thereby further improving the automation level of receiving.

[0036] The implementation principle of the high-pressure die-casting molding device for the chassis shell in this embodiment is as follows: During the die-casting process, the moving mold 21 moves closer to the fixed mold 22 until they are in contact. Simultaneously, the moving mold 21 moves, and the connecting rod 62 drives the abutment rod 61 to slide away from the abutment plate 32 within the abutment hole 6. At this time, the molding groove 3 is sealed, the return spring 51 abuts against the return plate 5, and the abutment plate 32 moves within the abutment groove 31. The abutment plate 32 seals the abutment groove 31, and its surface is flush with the bottom wall of the molding groove 3. After die-casting, the moving mold 21 slides away from the fixed mold 22. At this time, the connecting rod 62 drives the abutting rod 61 to approach the abutting plate 32, and the abutting rod 61 can abut against the abutting plate 32. The guide rod 4 slides in the guide groove 41 to guide the abutting plate 32, so that the abutting plate 32 can abut against the shell formed in the forming groove 3. Under the force of the abutting plate 32, the shell in the forming groove 3 can be detached from the forming groove 3, realizing automatic detachment. When the fixed mold 22 moves, the connecting rod 62 drives the abutting rod 61 to move, automatically removing the formed shell from the mold, reducing manual labor, improving production efficiency, and making control convenient and quick, thus achieving low cost.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
