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.

[0015] Please see Figures 1-4 This utility model provides a technical solution: a pin mold fixing device, including a base 1, which is square. A motor 2 is installed at any one diagonal position of the upper end of the base 1, and bearing seats 3 and 4 are installed at the other diagonal positions. A lead screw 5 is fixedly connected to the output end of the motor 2. The shaft of the lead screw 5 has two threads with different directions. The other end of the lead screw 5 is fixedly connected to a worm gear 6. The shaft of the worm gear 6 has a worm thread 7. The other end of the worm gear 6 is connected to the bearing seat 3. The motor 2 is a bidirectional motor.

[0016] A second lead screw 8 is provided above the first lead screw 5. The shaft of the second lead screw 8 has two threads with different directions. A worm gear 9 is fixedly connected to the shaft of the second lead screw 8. The worm gear 9 meshes with the worm thread 7. The two ends of the second lead screw 8 are respectively connected to the bearing seats 2 4 at different diagonal positions on the upper end of the base 1. Both ends of the shafts of the first lead screw 5 and the second lead screw 8 are provided with shoulders 10.

[0017] A limiting rod 11 is provided in a direction perpendicular to the axis of the lead screw 2 8. The limiting rod 11 is located below the lead screw 2 8, and the two ends of the limiting rod 11 are respectively connected to the bearing seats 3 at different diagonal positions of the base 1.

[0018] A limiting rod 12 is provided in a direction perpendicular to the axis of lead screw 5. The limiting rod 12 is located above lead screw 5, and its two ends are respectively connected to bearing seats 4 at different diagonal positions of base 1.

[0019] At this time, lead screw 5 and limit rod 11 are located above one set of opposite sides of base 1, and lead screw 8 and limit rod 12 are located above another set of opposite sides of base 1. Both lead screw 8 and limit rod 12 are located above lead screw 5 and limit rod 11 (e.g., Figure 4 (As shown).

[0020] Two sets of baffles 13 are provided above the base 1. One end of the baffle 13 is threaded to the lead screw 5, and the other end is slidably connected to the limit rod 11. The two sets of baffles 13 are respectively connected to threads of different directions on the shaft of the lead screw 5.

[0021] Above the first baffle 13, there is a second baffle 14. One end of the second baffle 14 is threadedly connected to the second lead screw 8, and the other end is slidably connected to the second limit rod 12. The two sets of second baffles 14 are respectively connected to threads of different directions on the shaft of the second lead screw 8.

[0022] The base 1 has a sliding groove 15 in the area below the limiting rod 11. Both ends of the sliding groove 15 are equipped with electric telescopic rods 17. The opposite ends of the output shafts of the two sets of electric telescopic rods 17 are provided with sliders 19. The sliders 19 are slidably connected to the sliding groove 15 and are fixedly connected to the baffle 13.

[0023] The base 1 has a sliding groove 16 located below the limiting rod 12. Both ends of the sliding groove 16 are equipped with electric telescopic rods 18. The output shafts of the two sets of electric telescopic rods 18 are provided with sliders 20 at opposite ends. The sliders 20 are slidably connected to the sliding groove 16 and are fixedly connected to the baffle 14.

[0024] Working principle: The opposite side of the two sets of baffles 13 and the two sets of baffles 14 is defined as the working area. In the initial state, each set of baffles is located at the farthest relative distance, and the working area is the largest at this time. The worker places the mold to be fixed at any position in the working area.

[0025] Start motor 2, which drives lead screw 5 to rotate. Since lead screw 5 has threads with different directions of rotation on its shaft, and both sets of threads are connected to a set of baffles 13, lead screw 5 drives the two sets of baffles 13 to move in opposite directions.

[0026] Lead screw 5 drives worm 6 to rotate. Since worm thread 7 meshes with worm wheel 9, worm 6 drives worm wheel 9 to rotate, and worm wheel 9 drives lead screw 8 to rotate.

[0027] Since the screw 8 has threads with different directions of rotation on its shaft, and both sets of threads are connected to baffles 14, the screw 8 drives the two sets of baffles 14 to move towards each other, and the shoulder 10 prevents the baffles from colliding with the bearing housing.

[0028] At this point, the two sets of baffles 13 move towards each other, and the two sets of baffles 24 move towards each other, causing the working area to gradually shrink. Finally, baffles 13 and baffles 24 fit against the mold surface, achieving the initial fixation of the mold.

[0029] After the initial fixing of the mold is completed, the stamping operation is carried out to prepare the insert. During the stamping, the mechanical vibration transmitted to the mold may cause the mold to shift due to the thread force between each set of baffles and lead screws. Therefore, each set of electric telescopic rods and sliders are used to reinforce the mold.

[0030] Specifically, during the stamping operation, the electric telescopic rod 17 and electric telescopic rod 28 are activated. The output ends of electric telescopic rod 17 and electric telescopic rod 28 extend outward until they contact slider 19 and slider 20 respectively. At this time, the electric telescopic rods apply a certain pushing force to the sliders. When the mold is subjected to mechanical vibration and deviates, it must not only overcome the thread force of each set of baffles, but also overcome the pushing force of the electric telescopic rods, further improving the mold's fixing effect.
