[0013] (III) Beneficial Effects

[0014] Compared with the prior art, this utility model provides a mold for producing automobile engine brackets, which has the following advantages:

[0015] This mold for manufacturing automotive engine brackets comprises an upper mold mechanism, an installation mechanism, a lower mold mechanism, and a fixing mechanism. The upper mold is placed at a suitable position below a U-shaped plate, positioning the mounting plate outside the vertical plate. During installation, simply push the upper mold upwards. As the mounting plate moves upwards, it presses against the side support plates, causing the locking blocks to move in opposite directions. Once the mounting plate reaches the top of the support plates, the fixing spring returns to its original position, pushing the moving plate in the opposite direction. This causes the locking blocks to extend to the inside of the vertical plate, thus fixing the mounting plate to the vertical plate, completing the installation of the upper mold. To disassemble the upper mold, pull the pull ring to remove the locking blocks from the inside of the vertical plate, releasing the fixing to the mounting plate. Then, remove the upper mold from the outside of the vertical plate, completing the disassembly of the upper mold. When the lower mold is fixed, it is first placed inside the base. The servo motor is started, and its output shaft drives the threaded rod to rotate. The threaded rod is threadedly connected to the threaded block. When the threaded rod rotates, the threaded block moves along the axial direction of the threaded rod. When the threaded block moves, it slides in the moving frame through the connecting plate and the round rod. The moving frame drives the right-angle plate to move, so that one end of the right-angle plate engages with the top frame of the lower mold, thereby fixing the lower mold on the base and preventing the lower mold from moving during the molding process, thus ensuring the molding quality. When disassembling the lower mold, simply start the servo motor to rotate in the opposite direction, causing the right-angle plate to separate from the top frame. The lower mold can then be taken out through the handle, achieving the purpose of easy disassembly and replacement of the mold base. Attached Figure Description

A locking block 58 extending to the inner side of the vertical plate 51 is fixedly installed on one side of the support plate 57. By locking into the corresponding slot or structure on the mounting plate 43, the mounting plate 43 is fixed, thereby firmly installing the upper mold 41 under the U-shaped plate 32.

[0032] The lower mold mechanism 6 includes a lower mold 61. The lower mold 61, which extends to the top of the base 1, is movably installed on the inner side of the base 1. It is another forming part of the mold and cooperates with the upper mold 41 to form a complete cavity for forming the engine bracket. At the same time, its movable installation method facilitates product demolding and maintenance and replacement of the lower mold 61. A top frame 62 is fixedly installed on the top of the lower mold 61. Handles 63 are fixedly installed on both the front and rear sides of the top frame 62 to provide gripping points for operators, making it convenient to carry, install and disassemble the lower mold 61.

[0033] The fixing mechanism 7 includes a mounting groove 701. The top of the base 1 has a mounting groove 701. A servo motor 702 is fixedly mounted on the rear side of the inner wall of the mounting groove 701. A threaded rod 703, rotatably connected to the front side of the inner wall of the mounting groove 701, is fixedly mounted on the output shaft of the servo motor 702. A threaded block 704 is threadedly connected to the outer side of the threaded rod 703. A connecting plate 705 is fixedly mounted on the top of the threaded block 704. Two support rods 706 are fixedly mounted between the left and right sides of the inner wall of the mounting groove 701. Two... The moving block 707 has a moving frame 708 fixedly installed between the front and rear moving blocks 707. Right angle plates 709 extending to the top of the base 1 are fixedly installed on the opposite sides of the two moving frames 708. The side wall of the top frame 62 has a locking hole adapted to the right angle plate 709. One end of the right angle plate 709 is locked to the top frame 62. The top of the connecting plate 705 has two round rods 710 fixedly installed and slidably connected to the two moving frames 708 respectively. The inside of the moving frame 708 has a slot adapted to the moving trajectory of the round rod 710. The slot is designed to be inclined.

[0034] The demolding assembly 8 includes a support frame 81. Two support frames 81 are fixedly installed on the inner top wall of the base 1 and respectively fixedly connected to the left and right sides of the inner wall of the base 1. A lifting plate 82 is slidably installed between the two support frames 81. A pushing block 83 extending to the inner side of the lower mold 61 is fixedly installed on the top of the lifting plate 82. A movable frame 84 is fixedly installed inside the lifting plate 82. A servo motor 85 is fixedly installed on the inner top wall of the base 1. A swing plate 86 extending to the inner side of the movable frame 84 is fixedly installed at the output shaft of the servo motor 85. The left side of the swing plate 86... Both sides are fixedly installed with circular rods 87 that are slidably connected to the movable frame 84. When the servo motor 85 is started, its output shaft drives the swing plate 86 to swing. The circular rods 87 on the swing plate 86 slide inside the movable frame 84, thereby driving the movable frame 84 to move up and down. The movable frame 84 is fixed on the lifting plate 82. The lifting plate 82 moves up and down with the movable frame 84. The pushing block 83 on the lifting plate 82 extends to the inside of the lower mold 61. When the lifting plate 82 moves upward, the pushing block 83 pushes the formed car engine bracket out of the lower mold 61, realizing demolding.

[0035] During use, check that all components of the mold are intact, including the lifting assembly 3, mounting mechanism 5, fixing mechanism 7, and demolding assembly 8, to ensure they are functioning properly. Ensure that electrical components such as the electric push rod 31, servo motor 702, and servo motor 85 are correctly wired and functioning correctly. Place the lower mold 61 inside the base 1, extending its top to the top of the base 1. Adjust the position of the lower mold 61 using the handle 63 to accurately position it. Activate the servo motor 702 to engage the right-angle plate 709 with the top frame 62 of the lower mold 61, firmly fixing the lower mold 61 to the base 1. Then, install the upper mold 41 below the U-shaped plate 32 and secure it firmly using the mounting mechanism 5, ensuring the mounting plate 43 is positioned... On the outside of the vertical plate 51, during installation, simply push the upper mold 41 upwards. When the mounting plate 43 moves upwards, it will squeeze the two side support plates 57, causing the locking blocks 58 to move in opposite directions. When the mounting plate 43 moves to the top of the support plate 57, the fixing spring 56 returns to its original state, pushing the moving plate 53 to move in the opposite direction, so that the locking blocks 58 extend to the inside of the vertical plate 51, thereby fixing the mounting plate 43 on the vertical plate 51 and completing the installation of the upper mold 41. Control the electric push rod 31 to work, so that the upper mold 41 moves downwards and closes with the lower mold 61 to form a complete mold cavity. The molten automobile engine bracket material is injected into the mold cavity through the connecting pipe 42 on the upper mold 41. Wait for the material to cool and solidify in the cavity to form the preliminary shape of the engine bracket. The cooling time is determined according to the material properties and product requirements. After the operation is completed, the electric push rod 31 is controlled to work in reverse, so that the upper mold 41 moves upward and separates from the lower mold 61, thus completing the mold opening. The servo motor 85 is started to move the push block 83 upward, pushing the formed car engine bracket out of the lower mold 61, thus achieving demolding. The demolded car engine bracket is taken out of the mold for inspection and subsequent processing. The residual material and impurities in the upper mold 41 and the lower mold 61 are cleaned to keep the mold cavity clean for the next use. According to the disassembly principle of the installation mechanism for the upper mold, the upper mold 41 is removed from under the U-shaped plate 32. The servo motor 702 is started to separate the right angle plate 709 from the top frame 62 of the lower mold 61, releasing the fixation of the lower mold 61. Then the lower mold 61 is taken out from the inside of the base 1.

[0036] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0037] In summary, this mold for producing an automotive engine bracket, by setting up an upper mold mechanism 4, an installation mechanism 5, a lower mold mechanism 6, and a fixing mechanism 7, places the upper mold 41 at a suitable position below the U-shaped plate 32, so that the mounting plate 43 is located outside the vertical plate 51. During installation, simply push the upper mold 41 upward. When the mounting plate 43 moves upward, it will squeeze the two side support plates 57, causing the locking blocks 58 to move in opposite directions. When the mounting plate 43 moves to the top of the support plates 57, the fixing spring 56 returns to its original state, pushing the moving plate 53 to move in the opposite direction, so that the locking blocks 58 extend to the inside of the vertical plate 51, thereby fixing the mounting plate 43 to the vertical plate 51, completing the installation of the upper mold 41. When removing the upper mold 41, pull the pull ring 55 to move the locking blocks 58 out from the inside of the vertical plate 51, releasing the fixing of the mounting plate 43. Then, remove the upper mold 41 from the outside of the vertical plate 51, completing the disassembly of the upper mold 41. When fixing the lower mold 61, first place it inside the base 1, and the servo motor 702 starts. Its output shaft drives the threaded rod 703 to rotate. The threaded rod 703 is threadedly connected to the threaded block 704. When the threaded rod 703 rotates, the threaded block 704 moves along the axial direction of the threaded rod 703. When the threaded block 704 moves, it slides in the moving frame 708 through the connecting plate 705 and the round rod 710. The moving frame 708 drives the right angle plate 709 to move, so that one end of the right angle plate 709 is engaged with the top frame 62 of the lower mold 61, thereby fixing the lower mold 61 on the base 1 and preventing the lower mold 61 from moving during the molding process, thus ensuring the molding quality. When disassembling the lower mold 61, it is only necessary to start the servo motor 702 to rotate in the opposite direction, causing the right angle plate 709 to separate from the top frame 62. Then the lower mold 61 can be taken out through the handle 63. This achieves the purpose of easy disassembly and replacement of the mold base, and solves the problem that the mold base is fixed and the surface is prone to thermal fatigue cracks after long-term use, which leads to mold damage and makes it impossible to disassemble and replace it separately, thus affecting the service life of the mold.
