The protective covers 14 are arranged on the outside of the transmission gear 1 32 and the transmission gear 2 35. Fixing parts 2 15 are provided at the positions corresponding to the fixing parts 12 on both sides of the protective cover 14. The corresponding fixing parts 12 and fixing parts 2 15 are connected by a bolt group 16, and the motor 36 is arranged on the outer wall of one of the protective covers 14;

[0033] The mold fixing assembly 4 includes a "U"-shaped placement plate 40 arranged on the mounting platform 1, and a pair of driving members 41 are provided at the bottom of the "U"-shaped placement plate 40. The driving members 41 are located in the movable groove 10 and are threadedly connected to the lead screw 33. Slide rails 42 are symmetrically provided on both sides of the bottom of the "U"-shaped placement plate 40. The slide rails 42 are movably arranged in the slide groove 11. Telescopic cylinders 45 are provided on the outer walls of both sides of the "U"-shaped placement plate 40. After the telescopic rod of the telescopic cylinder 45 passes through the side wall of the "U"-shaped placement plate 40, a clamping plate 46 is provided on the top of the telescopic rod. The front of the clamping plate 46 is provided with an anti-slip pad 47. A placement groove 44 is provided on the inner bottom surface of the "U"-shaped placement plate 40, and a clamping groove 43 is provided in the middle of the placement groove 44;

[0034] A slot 13 passing through the mounting platform 1 is provided at the center position of the mounting platform 1, and the center positioning assembly 2 includes a limit cover 23 arranged at the bottom of the mounting platform 1. The limit cover 23 is arranged on the slot 13, and a column 20 is movably arranged in the slot 13. A limit plate 21 is provided at the bottom of the column 20, and the limit plate 21 is located in the limit cover 23. A pull rod 22 is provided at the bottom of the limit plate 21, and one end of the pull rod 22 is located on the outside of the limit cover 23. An extrusion spring 24 is provided on the outside of the pull rod 22, and the extrusion spring 24 is arranged between the limit plate 21 and the inner bottom surface of the limit cover 23.

[0035] Preferably, by providing a protective cover 14, the transmission gear 1 32 and the transmission gear 2 35 in the exchange assembly 3 can be effectively protected, the influence of dust, debris, etc. on the transmission components can be reduced, and the service life of the device can be extended;

[0036] By providing the anti-slip pad 47, the friction between the clamping plate 46 and the mold is increased, the stability of the mold fixation is further improved, and the shaking of the mold during operation is reduced.

[0037] When installing the device, the center of the mounting platform 1 needs to be precisely aligned with the downward pressing position of the impact device.

[0038] During use, several different molds are first placed in the placement slots 44 of several "U"-shaped placement plates 40. Then, the telescopic cylinders 45 on both sides are simultaneously activated to cause them to extend their telescopic rods synchronously. After the clamping plates 46 on both sides firmly clamp the molds, the mold installation work is completed.

[0039] When one of the molds needs to be used, the pull rod 22 must be manually pulled first, so that the top end of the plug post 20 protruding from the outside of the mounting platform 1 is retracted into the slot 13. Then, the motor 36 is controlled to rotate forward, so that it drives the rotating shaft 30 to rotate. When the rotating shaft 30 starts to rotate, it drives the two transmission gears 1 32 to rotate simultaneously. At this time, the transmission gear 1 32 and the transmission gear 2 35 on both sides engage with each other for transmission, thereby causing the two lead screws 33 to rotate synchronously. In this process, the driving parts 41 at the bottom of the several "U"-shaped placement plates 40 will drive the several "U"-shaped placement plates 40 to move synchronously in one direction.

[0040] When the "U"-shaped placing plate 40 with the required mold installed moves to above the slot 13, the pull rod 22 can be released, and then the rotation speed of the motor 36 can be reduced to make the "U"-shaped placing plate 40 move forward slowly. When the slot 43 on the "U"-shaped placing plate 40 is aligned with the slot 13, under the action of the extrusion spring 24, the plug 20 will be quickly lifted upward and inserted into the slot 43, and then the motor 36 will be immediately turned off. At this time, the mold is exactly located in the center of the mounting platform 1 and just below the punching machine, and then the punching operation can be carried out.

[0041] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents of such scope and metes and bounds.
