[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-5 A replaceable mold for die casting automotive parts includes a worktable 1. A motor 2 is fixedly mounted on the outer wall of the worktable 1. A lead screw 3 is fixedly mounted on the output shaft of the motor 2. A slide 5 is threadedly connected to the outer wall of the lead screw 3. A mounting plate 6 is fixedly mounted on the outer wall of the slide 5. A movable seat 7 is fixedly mounted at the end of the mounting plate 6. Adjusting screws 14 are provided on both outer walls of the movable seat 7. A handle 13 is fixedly mounted on one end of the adjusting screw 14. A clamping plate 15 is rotatably connected to the other end of the adjusting screw 14. A lower mold 12 is tightly fitted to the outer wall of the clamping plate 15. A through groove 8 is opened on the outer wall of the worktable 1. Limit grooves 9 are opened on both inner walls of the through groove 8. The bottom of the inner wall is fixedly equipped with a guide rail 11, the middle of the movable seat 7 is provided with a movable groove 17, the outer walls of the slide seat 5 and the movable seat 7 are both provided with sliding grooves 16, the top of the worktable 1 is fixedly equipped with a hydraulic cylinder 10, the outer wall of the worktable 1 is fixedly equipped with a straight plate 18 and a positioning plate 22, the outer wall of the straight plate 18 is fixedly equipped with a power supply 19 and an electromagnet 21, the outer wall of the positioning plate 22 is provided with a return spring 23, the end of the return spring 23 abuts against a rotating plate 24, a strong magnet 20 is fixedly equipped at one end of the rotating plate 24 near the straight plate 18, the middle of the rotating plate 24 is rotatably connected to a limit rod 25, and the inner wall of the worktable 1 is fixedly equipped with a crossbar 4.

[0022] In the above structure, the workbench 1, motor 2, lead screw 3, crossbar 4, slide 5, mounting plate 6, movable seat 7, through groove 8, and limiting groove 9 are designed so that during use, the user can move the slide 5 along the outer wall of the crossbar 4 by operating the motor 2, thereby pushing the movable seat 7 to slide along the outer wall of the guide rail 11. This moves the movable seat 7 outside the workbench 1, making it easier for the user to rotate the handle 13 to replace the lower mold 12. This achieves the effect of replacing the lower mold 12 and also improves the safety of the user during the replacement process.

[0023] In a preferred embodiment, a controller is fixedly mounted on the outer wall of the straight plate 18, and the controller is electrically connected to the power supply 19 and the electromagnet 21 respectively.

[0024] In the above structure, the power supply 19, electromagnet 21 and controller structure enable the user to make the rotating plate 24 rotate by energizing the electromagnet 21 during use, thereby achieving the effect of automatically locking the handle 13, thus improving the automation of the mold during use and making it easier for the user to operate.

[0025] In a preferred embodiment, the outer wall of the rotating plate 24 is in close contact with the outer wall of the handle 13, and the handle 13 is fixedly connected to the movable seat 7.

[0026] In the above structure, the movable seat 7 and the handle 13 structure enable the rotating plate 24 to rotate and lock the handle 13, thereby preventing the clamping plate 15 from loosening and affecting the stability of the lower mold 12, thus ensuring the clamping effect of the clamping plate 15 on the lower mold 12 and improving the stability of the mold during use.

[0027] In a preferred embodiment, the outer wall of the guide rail 11 is slidably connected to the inner wall of the movable groove 17, and the outer wall of the slide block 5 is provided with a circular hole, and the inner wall of the circular hole is slidably connected to the outer wall of the crossbar 4.

[0028] In the above structure, the sliding block 5 structure allows the lead screw 3 to move the movable seat 7 to the outside of the worktable 1 during rotation by moving the sliding block 5. This prevents the user from reaching under the hydraulic cylinder 10 to replace the lower mold 12, thus ensuring that the user will not make any mistakes that could cause personal injury during the replacement of the lower mold 12, and improving the safety of the mold.

[0029] In a preferred embodiment, a connecting plate is fixedly mounted on the inner wall of the through groove 8, and the end of the lead screw 3 is rotatably connected to the outer wall of the connecting plate, and the top of the inner wall of the movable groove 17 is slidably connected to the top of the connecting plate.

[0030] In the above structure, the connecting plate and movable groove 17 structure ensure that the movable groove 17 is not obstructed during the movement of the slide block 5, thereby ensuring that the movable seat 7 can be moved to the outside of the worktable 1 for easy replacement by the user, and thus ensuring the normal use of the mold.

[0031] In a preferred embodiment, the outer wall of the limiting rod 25 is fixedly assembled with the outer wall of the worktable 1, and threaded holes are provided on both outer walls of the movable seat 7, and the inner wall of the threaded hole is threadedly connected to the outer wall of the adjusting screw 14.

[0032] In the above structure, through the setting of the adjusting screw 14 and the handle 13, the user can move the clamping plate 15 by rotating the handle 13, so as to facilitate the user to adjust the distance between the two clamping plates 15 to replace the lower mold 12 of different sizes, thereby improving the application range of the device.

[0033] Working principle: After the user assembles the mold, the die-casting operation is performed by extending the output shaft of the hydraulic cylinder 10. When the lower mold 12 needs to be replaced, the user can rotate the lead screw 3 by operating the motor 2, thereby causing the slide 5 to slide along the outer wall of the crossbar 4. This causes the mounting plate 6 to push the moving seat 7 to slide along the outer wall of the guide rail 11, thus achieving the effect of pushing the moving seat 7 to the outside of the worktable 1. This ensures that the user can replace the lower mold 12 and also improves the user's safety during the replacement process. After the replacement is completed, the moving seat 7 is reset, and the user can continue the die-casting operation. During the operation, the electromagnet 21 is energized to rotate the rotating plate 24, thereby causing the outer wall of the handle 13 to fit tightly against the outer wall of the rotating plate 24, thus achieving the effect of locking the handle 13 and improving the safety of the mold during use.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
