[0021] The following will further elaborate on the automatic feeding structure inside the mold of this utility model with reference to specific embodiments, so as to help those skilled in the art to have a more complete, accurate and in-depth understanding of the technical solution of this utility model.

[0022] Example 1

[0023] like Figure 1-5 As shown, the automatic feeding structure inside the mold in this embodiment includes a driver 100, a sliding assembly, a sheet metal strip assembly, and a base 400. The base 400 includes an upper base and a lower base. A sliding groove 410 is provided on the upper surface of the lower base, and the sheet metal strip assembly is disposed on the sliding groove 410. The upper base is fastened to the lower base, restricting the sheet metal strip assembly between the upper and lower bases. The sliding assembly includes a sliding block 200, a forced material clamping hook 210, a rotating shaft limiting screw 220, a return spring 230, and a spring fixing pin 240. The front end of the return spring 230 is fixed to the sliding block 200 by the spring fixing pin 240, and the rear end of the return spring 230 is fixed to the upper base by the spring fixing pin 240. The sliding block 200 is elastically connected to the upper base via the return spring 230 and reciprocates along the feeding direction on the material feeding groove 410. The forced clamping hook 210 is mounted on the front end of the sliding block 200 via the pivot limit screw 220. Specifically, the front end of the sliding block 200 is provided with a connecting end, and the forced clamping hook 210 is mounted on the connecting end via the pivot limit screw 220. The upper base is provided with a guide groove for guiding the sliding block 200, and the front end of the guide groove is provided with a clamping hook groove to accommodate the forced clamping hook 210. The rear end face of the sliding block 200 is provided with a mating end that cooperates with the driver 100. The sheet metal strip assembly includes a sheet metal strip 300, which is formed by a boundary contour 320 to form a frame structure. The frame structure has multiple crossbeams, and the crossbeams are provided with sheet metal strip clamping grooves 310, while the space between adjacent crossbeams is a hollow structure. The forced clamping hook 210 reciprocates with the pivot limiting screw 220, thereby engaging and disengaging with the slot 310 on the sheet material strip. The forced clamping hook 210 drives the sheet material strip 300 to move along the feeding direction on the sliding groove 410.

[0024] During production feeding, a notch is punched in the slot when the material is delivered to the first process stage, and feeding continues forward. When the front end of the sheet metal strip 300 contacts the forced clamping hook 210, feeding continues forward. At this time, the sheet metal strip 300 will push the forced clamping hook 210 to rotate around the pivot limit screw 220. When the sheet metal strip slot 310 is just engaged with the forced clamping hook 210 on the automatic feeding structure (e.g., ...), the feeding continues. Figure 6(As shown). At this time, the machine tool begins to close. During the stamping closing process, the machine tool moves downward with the upper die and the drive 100. The drive 100 drives the sliding block 200 to move along the feeding direction on the sliding groove 410 of the lower base 400. Applying the working principle of the hinge, the forced clamping hook 210 is engaged with the clamping groove 310 on the sheet metal strip. The forced clamping hook 210 clamps the sheet metal strip 300 and moves it along the feeding direction in the sliding groove 410 (as shown). Figure 7 (As shown); the machine tool continues to move downwards until it is fully closed, at which point the feeding process ends and the sheet metal strip is delivered to the designated position (e.g., Figure 8 (As shown); At this time, the machine tool begins to move upward, driving the upper die and driver 100 to move upward together. Meanwhile, under the action of the return spring 230, the sliding block 200 begins to retract in the opposite direction of the feeding direction within the material groove 410 of the base 400, until it retracts to the position where the sheet metal strip slot 310 just engages with the forced clamping hook 210 on the automatic feeding structure, completing one stroke and preparing for the next. The reciprocating motion achieves the purpose of automatic strip feeding during the stamping process.

[0025] The assembly process of all components in this patent is as follows: the driver is installed and fixed on the upper mold assembly, the sliding block is installed on the base, so that the sliding block can slide back and forth in a directional and fixed distance in the base, the forced material clamping hook is installed on the sliding block through the rotating shaft limit screw, so that the forced material clamping hook can rotate on the sliding block with the rotating shaft limit screw as the axis, and the return return spring is fixed on the sliding block and the base respectively through two return return spring fixing pins, so that the sliding block and the base are connected together through the return return spring.

[0026] This embodiment features a reciprocating feeding structure on a base. First, the sheet metal strip is fed to a designated position (where the forced clamping hook engages with a slot on the strip). Then, the downward thrust of the driver pushes a sliding block along the feeding direction. Applying the hinge principle, the sliding block drives the forced clamping hook, which engages the sheet metal strip and moves it forward. The driver moves upward, and the sliding block moves backward under the action of a return spring, until the forced clamping hook is precisely engaged with the slot on the strip, completing one stroke. The automatic feeding of the sheet metal strip is achieved through repeated up-and-down thrusting actions of the driver. This embodiment's internal automatic feeding structure is ingeniously designed, structurally sound and stable, and can automatically complete the feeding action without adjusting the feeding mechanism. This saves equipment costs while improving work efficiency, significantly reducing the company's production costs.

Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvements made using the inventive concept and technical solution of the present invention are within the protection scope of the present invention.
