[0064] The two positioning slide bars 14 are slidably connected in the two positioning slide grooves 18 , and the rear ends of the two positioning slide bars 14 extend into the two limit grooves 11 through the two positioning slide grooves 18 .

[0065] Furthermore, two slide rail grooves 17 are both provided on the front side surfaces of the two extrusion blocks 9;

[0066] Among them, the rear inner walls of the two slide rail grooves 17 are inclined surfaces;

[0067] Among them, the two slide rail grooves 17 are arranged in a mirror image;

[0068] Among them, two mounting blocks 16 are fixedly connected to the rear end of the positioning slide rod 14;

[0069] The wheel 15 is rotatably connected between the two mounting blocks 16 .

[0070] Furthermore, the wheel 15 and the mounting block 16 are both located in the slide rail groove 17, and the rear surface of the wheel 15 contacts the rear inner wall of the slide rail groove 17;

[0071] Among them, two support springs 13 are fixedly connected to the rear surface of the sliding block 8;

[0072] The rear ends of the two support springs 13 are fixedly connected to the rear inner wall of the sliding groove 7, and the two support springs 13 are slidably sleeved on the outer surface of the positioning slide rod 14;

[0076] When in use, the rubber pad 3 is directly sleeved on the outer surface of the positioning block 5 through the limiting groove 11, and then the positioning block 5 is slid into the installation groove 4. When the positioning block 5 slides downward, it will contact the inclined surfaces of the two extrusion blocks 9, and when the positioning block 5 moves downward, the positioning block 5 is slidably connected with the extrusion block 9. At this time, the positioning block 5 pushes the two extrusion blocks 9 to move back to each other. At this time, the two extrusion blocks 9 also synchronously squeeze the first spring 12, causing the first spring 12 to be squeezed and deformed. When the positioning block 5 moves to its lower surface and fits the installation groove 4, the bottom wall of the fixing groove 6 and the connecting groove The bottom walls of 10 are in the same plane, and the two extrusion blocks 9 are pushed into the two fixing grooves 6 under the action of the released elastic force of the first spring 12, thereby fixing the positioning block 5.

The fixation is convenient and fast, and the locking mechanism is located in the workbench 1. The locking mechanism does not affect the cleaning work of the upper surface of the workbench 1 during the working process of the mold, which is convenient for the cleaning and maintenance of the workbench 1, and the locking installation efficiency is high, thereby increasing the disassembly efficiency of the mold locking device, thereby increasing the practicality of the device.

[0077] Furthermore, during disassembly, the sliding block 8 is pressed and the sliding block 8 slides backward. The sliding block 8 moves backward, driving the positioning slide bar 14, the wheel 15, and the mounting block 16 to move backward synchronously. In the process of the sliding block 8 moving backward, the two supporting springs 13 are squeezed, causing the supporting springs 13 to be squeezed and deformed. The wheel 15 moves backward and drives it to roll on the rear inner wall of the slide rail groove 17, thereby synchronously giving thrust in opposite directions to the two extrusion blocks 9, causing the two extrusion blocks 9 to move away from each other. When the two extrusion blocks 9 move away from the two fixed grooves 6, the positioning block 5 and the lower mold base 2 can be moved upward at this time, which makes disassembly convenient and quick, thereby increasing the disassembly efficiency of the mold locking device, saving manpower and increasing the practicality of the device.

[0078] Furthermore, in this solution, the workbench 1 and the lower die base 2 are both existing patents: CN202321957907.8, a prior art in a stamping die locking device, which will not be elaborated here.

[0079] Working principle: When the device is used, the rubber pad 3 is directly sleeved on the outer surface of the positioning block 5 through the limiting groove 11, and then the positioning block 5 is slid into the installation groove 4. When the positioning block 5 slides downward, it will contact the inclined surfaces of the two extrusion blocks 9, and when the positioning block 5 moves downward, the positioning block 5 is slidably connected with the extrusion block 9. At this time, the positioning block 5 pushes the two extrusion blocks 9 to move back to each other. At this time, the two extrusion blocks 9 also synchronously squeeze the first spring 12, causing the first spring 12 to be squeezed and deformed. When the positioning block 5 moves to its lower surface and fits with the installation groove 4, the fixing groove 6 is The bottom wall is in the same plane as the bottom wall of the connecting groove 10. Under the action of the released elastic force of the first spring 12, the two extrusion blocks 9 are pushed to slide into the two fixing grooves 6, thereby fixing the positioning block 5. At this time, the rubber pad 3 is squeezed between the lower mold base 2 and the workbench 1, and the lower mold base 2 is locked and fixed. The fixation is convenient and fast, and the locking mechanism is located in the workbench 1. The locking mechanism does not affect the cleaning work of the upper surface of the workbench 1 during the working process of the mold, which is convenient for the cleaning and maintenance of the workbench 1, and the locking installation efficiency is high, thereby increasing the disassembly efficiency of the mold locking device, thereby increasing the practicality of the device.
