The inner sides of the multiple groups of placement grooves 17 are all provided with balls 18 that are compatible with the annular groove 12. The outer ring of the socket 13 is sleeved with a fixed ring 19. The outer side of the fixed ring 19 is slidably connected with a sliding sleeve 20. The inner side of the sliding sleeve 20 is provided with a contact plate 21 that contacts the multiple groups of balls 18. One side of the contact plate 21 is connected to one side of the fixed ring 19 through a spring 22 sleeved on the outer ring of the socket 13.

[0028] Specifically, the bottom plate 1 is provided to provide a stable working platform for the stamping and forming of the carriage plate. The hydraulic telescopic rod 4 is provided to drive the upper template 7 and the lower template 10 to be pressed together, thereby facilitating the stamping and forming of the carriage plate. The sliding sleeve 20 is used to drive the contact plate 21 to move to one side and compress the spring 22. Then, the plug connector 11 of the upper template 7 and the lower template 10 is inserted into the plug groove 14. At the same time, the annular groove 12 can squeeze the multiple groups of balls 18 outward. When the plug connector 11 is inserted into the bottom of the plug groove 14, the sliding sleeve 20 is released. Under the action of the reaction force of the spring 22, the sliding sleeve 20 can drive the contact plate 21 and the sliding sleeve 20 moves in the opposite direction, and the resistance plate 21 moves in the opposite direction, and multiple groups of balls 18 can be squeezed inward, so that multiple groups of balls 18 can be squeezed through the inner side of the annular groove 12, so that the upper template 7 and the lower template 10 can be quickly connected and fixed.

[0029] Among them, a limiting groove 15 is provided at one end of the plug connector 11, and a limiting block 16 adapted to the limiting groove 15 is provided on the inner side of the plug-in slot 14. The limiting groove 15 and the limiting block 16 can be used to limit the installed mold to prevent the mold from being displaced. The inner side of the sliding sleeve 20 is located on one side of the contact plate 21 and is provided with an active cavity 23 that facilitates the outward movement of the ball 18. The active cavity 23 can facilitate the movement of the position of the ball 18 to facilitate the connection between the plug connector 11 and the plug-in slot 14.

[0030] Among them, the demoulding mechanism includes a contact head 25, and four groups of lifting rods 24 are passed through the bottom of the lower template 7. One end of the four groups of lifting rods 24 is connected to the contact head 25, and the other end of the four groups of lifting rods 24 is threadedly connected to the four groups of connecting seats 26 provided on the top of the lifting frame 27. The bottom of the lifting frame 27 is provided with two groups of rack columns 28, and the two groups of rack columns 28 are slidably connected to the two groups of fixed cylinders 29 provided on the top of the bottom plate 1. One side of the two groups of fixed cylinders 29 is penetrated by a first circular gear 30 that meshes with the rack column 28. The two groups of first circular gears 30 are meshed with the rack column 28. The circular gears 30 are connected by a connecting shaft 31. The two ends of the connecting shaft 31 are respectively rotatably connected to two sets of fixed plates 32 provided on the top of the base plate 1. One end of the connecting shaft 31 passes through the interior of the fixed plate 32 and is connected to a second circular gear 33. The second circular gear 33 is meshed with a rack plate 34. The rack plate 34 is slidably connected to the top of a slide 35 provided on the top of the base plate 1. One end of the rack plate 34 is connected to one end of an electric telescopic rod 36. The electric telescopic rod 36 is mounted on the top of a mounting plate 37 provided on the top of the base plate 1.

[0031] When the lifting rod 24 moves to the lowest point, the contact head 25 is flush with the bottom of the inner cavity of the lower template 10. By starting the electric telescopic rod 36, the electric telescopic rod 36 can drive the rack plate 34 to move to one side along the slide 35. The rack plate 34 can drive the second circular gear 33 to rotate under the action of meshing with the second circular gear 33.

[0032] Wherein, limiting plates 6 are provided on both sides of the pressing plate 5, and the two groups of limiting plates 6 are respectively slidably connected to the two groups of connecting rods 2. By providing the limiting plates 6, the up and down movement of the pressing plate 5 can be limited, so that the pressing plate 5 can drive the upper template 7 to move up and down more stably, facilitating better stamping and forming of the carriage plate.

[0033] Working principle: First, through the provided hydraulic telescopic rod 4 and pressing plate 5, the upper template 7 and the lower template 10 can be driven to be pressed together, facilitating the stamping and forming of the carriage plate. After the carriage plate is stamped and formed, by starting the electric telescopic rod 36, the electric telescopic rod 36 can drive the rack plate 34 to move to one side. The rack plate 34 can drive the second circular gear 33 to rotate. The second circular gear 33 can drive the connecting shaft 31 to rotate. The connecting shaft 31 can drive the two groups of first circular gears 30 to rotate. The two groups of first circular gears 30 can drive the two groups of rack columns 28 to move upward along the two groups of fixed cylinders 29 respectively. The two groups of rack columns 28 can drive the lifting frame 27, the four groups of lifting rods 24 and the abutting heads 25 to move upward. Thus, the four groups of abutting heads 25 can push the stamped and formed carriage plate upward out of the interior of the lower template 10, facilitating the removal of the stamped and formed carriage plate.

[0034] When the mold needs to be replaced, by sliding the sliding sleeve 20, the sliding sleeve 20 can drive the abutting plate 21 to move to one side and compress the spring 22. Then, the insertion joints 11 of the upper template 7 and the lower template 10 are inserted into the insertion slots 14. At the same time, the annular clamping groove 12 can squeeze the multiple spheres 18 outward. When the insertion joint 11 is inserted to the bottom of the insertion slot 14, the sliding sleeve 20 is released. Under the action of the reaction force of the spring 22, the sliding sleeve 20 can drive the abutting plate 21 and the sliding sleeve 20 to move in the opposite direction. While the abutting plate 21 moves in the reverse direction, it can squeeze the multiple spheres 18 inward, so that the multiple spheres 18 can be squeezed through the inside of the annular clamping groove 12, thus completing the quick connection and fixation of the upper template 7 and the lower template 10. By operating in the reverse direction, the disassembly of the upper template 7 and the lower template 10 can be facilitated, and then the entire operation process can be completed.
