A protection box 10 is installed on the top of the guard plate 6. The side wall of the protection box 10 is provided with a box door. Opening the box door is convenient for maintenance of the hydraulic cylinder 8.

[0022] More specifically, the loading mechanism 2 includes a support frame 21, a feeding assembly 22 and a material guiding assembly 23. The support frame 21 is vertically installed on the top of the front side of the base 1, and the feeding assembly 22 is installed on the top of the support frame 21 along the front-to-back direction. The workpiece is delivered to the mold 5 through the feeding assembly 22. The material guiding assembly 23 is installed on the rear side of the upper surface of the feeding assembly 22, and the workpieces are transported to the feeding assembly 22 one by one through the material guiding assembly 23.

[0023] More specifically, the feeding assembly 22 includes a support seat 221, which is installed on the top of the support frame 21 along the front-to-back direction. Slide grooves 222 are provided on the left and right sides of the support seat 221 along the front-to-back direction. A linear cylinder 223 is installed on the front of the support seat 221. A movable plate 224 plugged into the inner cavity of the support seat 221 is installed on the output end of the linear cylinder 223, and the side wall of the movable plate 224 is plugged into the inner cavity of the slide groove 222. Slideways 225 are provided on the left and right ends of the rear side of the movable plate 224. A slider 226 that can slide up and down is plugged into the inner cavity of the slideway 225, and the slider 226 is in a dovetail shape to prevent the slider 226 from detaching from the slideway 225. A clamping cylinder 227 is installed on the rear side of the slider 226. It is located at the same horizontal plane as the upper surface of the clamp cylinder 227. During the loading process of the clamp cylinder, the workpiece is prevented from falling. The left and right sides of the clamp cylinder 227 are equipped with rollers 228 that are plugged into the inner cavity of the slide groove 222. The rollers 228 roll in the slide groove 222 to guide the clamp cylinder 227.

A material tray 232 is mounted on the top of the sleeve 231, and the material tray 232 is used to store the workpiece. The material tray 232 is tilted downward from front to back, so that the workpiece can move along the inclined surface of the material tray 232 to the discharge hole 233. A discharge hole 233 connected to the sleeve 231 is opened at the bottom of the material tray 232. A first motor 234 is installed at the center of the lower surface of the material tray 232, and a dial plate 235 for rotating it is installed at the output end of the first motor 234, so that the dial plate 235 drives the workpiece to move in the material tray 232, and a blocking rod 236 is horizontally installed on the rear side of the top of the material tray 232.

[0025] More specifically, the mold moving mechanism 4 includes a dustproof box 41, which is installed at the bottom of the turntable 3. The lower surface of the dustproof box 41 is equidistantly inserted with guide columns 42 that can slide up and down along the circumferential direction. The top of the guide column 42 is installed at the bottom of the mold 5. The outer wall of the guide column 42 is polygonal in shape to prevent the guide column 42 from rotating during movement. The guide column 42 is hollow, and a plurality of teeth 43 are equidistantly installed on the inner side of the guide column 42 from top to bottom. A rotatable driving component 44 is installed at the bottom of the inner cavity of the dustproof box 41 through a support, and the guide column 42 is moved up and down by the cooperation of the driving component 44 and the teeth 43. A second motor 45 is installed on the lower surface of the dustproof box 41, and a gear 46 meshing with the driving component 44 is installed at the output end of the second motor 45.

[0026] More specifically, the driving assembly 44 includes a rotating drum 441 which is supported and installed at the bottom of the inner cavity of the dustproof box 41. A steel belt 442 is installed on the outer wall of the rotating drum 441, and the steel belt 442 is meshed with the teeth 43. An internal gear ring 443 meshed with the gear 46 is installed at the bottom of the inner wall of the rotating drum 441. The steel belt 442 is spirally distributed on the outer wall of the rotating drum 441 from top to bottom. When the rotating drum 441 rotates clockwise or counterclockwise, the inclined surface of the steel belt 442 can move downward or upward to change the height of the mold 5.

[0027] How it works Step 1: The mold 5 on the mold moving mechanism 4 is driven to rotate intermittently in sequence by the turntable 3. The hydraulic cylinder 8 has different strokes, and the punch 9 punches the workpiece step by step, thereby reducing the load of the hydraulic cylinder 8 and extending the service life; Step 2: When loading, pour the workpiece into the material tray 232, and rotate the paddle plate 235 under the drive of the first motor 234. The paddle plate 235 paddles the workpiece to move in the material tray 232. When blocked by the blocking rod 236, the workpiece is laid down. Since the material tray 232 is an inclined surface, the workpiece can slide toward the discharge hole 233. The workpiece is stacked in the sleeve 231, and the bottom workpiece falls on the pad 2210 to realize the placement of the workpiece. The clamping plate 229 clamps the workpiece on the pad 2210 through the clamping claw cylinder 227, and the movable plate 224 moves to the rear side under the drive of the linear cylinder 223. Since the roller 228 rolls in the slide 222, the clamping claw cylinder 227 can drive the workpiece to move horizontally to the rear side. When the roller 228 enters the inclined groove of the slide 222, the slider 226 cooperates with the slideway 225, and the clamping claw cylinder 227 descends, and the clamping plate 229 releases the workpiece, allowing the workpiece to fall on the mold 5. The linear cylinder 223 and the clamping claw cylinder 227 can realize automatic loading of the workpiece. Step three, when it is necessary to clean the iron filings on the turntable 3, the gear 46 is driven to rotate by the second motor 45, and the rotating drum 441 is rotated under the transmission condition of the gear 46 and the inner gear ring 443, and the steel belt 442 is inclined to squeeze the teeth 43 downward, so that the guide column 42 drives the mold 5 to move downward until the mold 5 and the turntable 3 are in the same plane, and then the mold 5 can be cleaned as the turntable 3 rotates, and the iron filings are cleaned more thoroughly.

[0028] The above are only preferred embodiments of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the protection scope of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.
