Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figures 1 to 6 As shown, the utility model provides a die-casting mold for an aluminum reinforcement plate of a car door, comprising a workbench 1, and a mold body 2 is arranged on the top of the workbench 1;

[0024] A fixing mechanism is arranged inside the workbench 1, and the fixing mechanism includes a fixing shell 3, which is fixedly connected to the inside of the workbench 1. There are two fixing shells 3, and springs 4 are elastically connected inside the two fixing shells 3. A moving plate 5 located inside the fixing shell 3 is fixedly installed on the opposite side of the spring 4. A fixing hole 15 is opened at the top of the workbench 1, and a connecting block 6 located inside the fixing hole 15 is fixedly installed on the top of the moving plate 5. A clamp 7 located at the top of the workbench 1 is fixedly installed on the top of the connecting block 6. A rotating rod 8 is rotatably connected to the bottom end of the workbench 1, and a belt 9 is fixedly installed on the opposite side of the moving plate 5. The other end of the belt 9 penetrates into the fixed shell 3, and the belt 9 is wound around the surface of the rotating rod 8. A gear 10 and a gear 2 11 are fixedly installed on one end of the rotating rod 8. A motor 12 is fixedly installed at the bottom end of the workbench 1, and the output end of the motor 12 is fixedly connected to the gear 2 11, and the gear 10 and the gear 2 11 are meshed with each other.

[0025] Adopting the above scheme: the operator can put the mold body 2 on the top of the workbench 1, and then drive the motor 12 to rotate the gear 2 11, because the gear 2 11 is meshed with the gear 10, and then when the gear 2 11 rotates, it will drive the gear 10 to rotate, and then the gear 10 and the gear 2 11 will drive the two rotating rods 8 to rotate at the same time, and then the rotating rod 8 will wrap the belt 9 on its surface, and then the belt 9 will pull the moving plate 15 to move relatively, and in the process of the moving plate 15 moving, the spring 4 will be squeezed, and then the moving plate 15 will drive the connecting block 16 to move inside the fixing hole 15, and then the connecting block 16 will drive the clamp 7 to move relatively, and then the opposite side of the clamp 7 will contact the diagonal of the mold body 2, so as to fix the mold body 2, and then the operator can put the raw material into the mold body 2, and then it can be stamped;

[0026] When the mold body 2 needs to be replaced, the motor 12 can be driven again to make the gear 2 11 rotate in the opposite direction, and then the rotating rod 8 will rotate accordingly, and then the belt 9 will move away from the surface of the rotating rod 8, and then the compressed spring 4 will push the movable plate 1 5, the connecting block 1 6 and the clamp 7 to reset, and then the clamp 7 will move away from the surface of the mold body 2, and then the limit on it will be cancelled, and then the operator can replace a different mold body 2.

[0027] like Figure 6 As shown, a stopper 16 is fixedly installed at the bottom and top of the fixed shell 3. The stopper 16 is square in design, and the surface of the stopper 16 contacts the surface of the movable plate 5.

[0028] By adopting the above solution, through the design of the stopper 16, when the movable plate 5 is reset, the surface of the movable plate 5 will contact the surface of the stopper 16, thereby blocking the movement of the movable plate 5 and preventing the movable plate 5 from escaping from the interior of the fixed shell 3 when the movable plate 5 is reset.

[0029] like Figure 6 As shown, a slide groove 13 is provided inside the fixing hole 15, and rollers 14 located inside the slide groove 13 are rotatably connected to both sides of the surface of the connecting block 6.

[0030] The above scheme is adopted: through the design of the slide groove 13 and the roller 14, since the surface of the roller 14 contacts the inner wall of the slide groove 13, when the connecting block 6 and the clamp 7 move, the roller 14 will roll inside the slide groove 13, thereby making the connecting block 6 and the clamp 7 move more smoothly.

[0031] like Figure 2As shown, the stamping mechanism is arranged at the top of the workbench 1, and the stamping mechanism includes a limit rod 17, the limit rod 17 is fixedly connected to the top of the workbench 1, the top of the limit rod 17 is fixedly installed with a mounting plate 18, the top of the mounting plate 18 is fixedly installed with a cylinder 19, the output end of the cylinder 19 penetrates downward through the mounting plate 18 and is fixedly installed with a movable plate 20, the bottom end of the movable plate 20 is provided with a stamping plate 21, and the top of the stamping plate 21 is fixedly installed with a connecting block 22 located inside the movable plate 20.

[0032] The above scheme is adopted: through the design of the stamping mechanism, the cylinder 19 can be driven, and then the output shaft of the cylinder 19 will push the movable plate 20 to move, and then the movable plate 20 will drive the stamping plate 21 and the connecting block 22 to descend, and then the connecting block 22 will enter the interior of the mold body 2, thereby stamping the raw material inside the mold body 2 to form it.

[0033] like Figure 5 As shown, a motor 23 is fixedly installed inside the movable plate 20, a bidirectional screw 24 is fixedly installed at the output end of the motor 23, a movable block 25 is threadedly connected to the surface of the bidirectional screw 24, and the number of the movable blocks 25 is two, and a limiting plate 26 is fixedly installed at the bottom end of each of the two movable blocks 25.

[0034] The above scheme is adopted: through the design of the moving block 25 and the limit plate 26, the connecting block 22 can be inserted into the interior of the moving plate 20, and then the motor 23 can be driven to rotate the bidirectional screw rod 24. Since the bidirectional screw rod 24 is threadedly connected with the moving block 25, when the bidirectional screw rod 24 rotates, it will drive the moving block 25 and the limit plate 26 to move relative to each other. Since the connecting block 22 is a T-shaped design, the limit plate 26 will contact the surface of the connecting block 22, and then the limit plate 26 will fix the stamping plate 21 to the bottom end of the moving plate 20.

[0035] like Figure 1 and Figure 6 As shown, a baffle 27 is fixedly installed inside the movable plate 20, and there is a gap between the top of the baffle 27 and the bottom of the movable block 25. Threaded plates 28 are fixedly installed on both left and right ends of the workbench 1, and the number of threaded plates 28 is four.

[0036] The above scheme is adopted: through the design of the baffle 27, after the connecting block 22 enters the interior of the movable plate 20, the top end of the connecting block 22 will contact the bottom end of the baffle 27, and then it can be positioned, so as to facilitate the limiting plate 26 to fix the connecting block 22, and there is a gap between the baffle 27 and the movable block 25, so that the baffle 27 will not interfere with the movement of the movable block 25; through the design of the threaded plate 28, the fixing screw can be inserted into the interior of the threaded plate 28, and then the device can be fixed, thereby increasing the stability of the device operation.

[0037] The working principle and use process of this utility model:

[0038] First, the operator can place the mold body 2 on the top of the workbench 1, and then insert the second connecting block 22 into the inside of the second moving plate 20. When the top of the second connecting block 22 contacts the bottom of the baffle 27, the second motor 23 can be driven to rotate the bidirectional screw 24, and then the moving block 25 and the limiting plate 26 will move relative to each other, and then the limiting plate 26 will fix the stamping plate 21 and the second connecting block 22;

[0039] Then the motor 12 can be driven to rotate the gear 2 11, and then the gear 2 11 will drive the gear 10 to rotate, and then the gear 2 11 and the gear 10 will drive the two rotating rods 8 to rotate, and then the belt 9 will drive the moving plate 1 5, the connecting block 1 6 and the clamp 7 to move relative to each other, and then the opposite side of the clamp 7 will contact the diagonal of the mold body 2, and then the clamp 7 will fix the mold body 2;

[0040] After the fixation is completed, the raw material can be placed inside the mold body 2, and then the cylinder 19 can be driven, and then the output shaft of the cylinder 19 will push the movable plate 20 to move, and then the movable plate 20 will drive the stamping plate 21 and the connecting block 22 to descend, and then the connecting block 22 will stamp the raw material inside the mold body 2 to shape it, and finally complete the operation process.
