Detailed Implementation
[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.
[0024] Example
[0025] Please refer to the attached document carefully. Figure 1 , 3As shown in Figure 5, a metal sheet stamping device includes a lower die frame 10, an upper die frame 11 suspended at the top of the lower die frame 10, a stripper plate 12 fixedly installed at the top of the lower die frame 10, a lower plastic frame 13 snapped onto the top of the stripper plate 12, a support component 14 movably provided at the bottom of the stripper plate 12, snap-fit components 15 at both ends of the stripper plate 12, and a pop-out component 16 on one side of the stripper plate 12. A lifting frame 17 is movably suspended at the bottom of the upper die frame 11, an upper plastic plate 18 is inserted into the bottom of the lifting frame 17, and edge-stopping components 19 are provided at both ends of one side of the lifting frame 17. The snap-fit component 15 includes two through slots 15 formed on both sides of the mounting frame 123. 1. A baffle 152 is provided on the outside of the through groove 151. A first conical pin 153 is movably provided inside the through groove 151. The first conical pin 153 is connected to the baffle 152 by multiple first springs 154. Conical slots 155 for fitting the first conical pin 153 are provided on both sides of the lower plastic frame 13. The edge component 19 includes a sliding sleeve 191 fixed to both ends of the outside of the T-shaped slot 171. A second conical pin 192 is movably inserted inside the sliding sleeve 191. One end of the second conical pin 192 is connected to the inside of the sliding sleeve 191 by a third spring 193. A push button 194 is fixedly connected to one side of the second conical pin 192.
[0026] As described above, when installing the lower plastic frame 13, the unloading plate 12 engages with the lower plastic frame 13 via the mounting frame 123, pushing the lower plastic frame 13 into the mounting frame 123. Due to the conical design, the first conical pin 153 and the second conical pin 192 can automatically retract through the conical structure when installing the lower plastic frame 13 or the upper plastic plate 18, facilitating installation. The first conical pin 153 of the engaging component 15 compresses the first spring 154 under the pushing of the lower plastic frame 13 until the conical head is embedded in the conical slot 1 of the lower plastic frame 13. 55. Lock the lower plastic frame 13 in position. The upper plastic plate 18, which is hoisted by the upper mold frame 11, is inserted into the T-slot 171 of the hoisting frame 17 through the pull plate 181. After it is fully inserted into the T-slot 171, the second cone pin 192 of the edge-blocking component 19 blocks the side wall of the pull plate 181 under the push of the third spring 193, thus fixing the upper plastic plate 18. When it is necessary to remove the lower plastic frame 13 or the upper plastic plate 18, it is necessary to manually move the other end of the first cone pin 153 or push the push button 194 to quickly remove it.
[0027] Please refer to the attached document carefully. Figure 1 , 2As shown in Figures 3, 4, and 5, a rectangular discharge groove 121 is provided at the bottom of the discharge plate 12, a discharge chute 122 is provided on one side of the discharge plate 12, and a mounting frame 123 is provided at the top of the discharge plate 12; the support component 14 includes a bidirectional threaded rod 141 rotatably mounted at both ends inside the rectangular discharge groove 121, two sliding grooves 142 are provided on both sides of the rectangular discharge groove 121, and two metal support plates 143 are externally threaded to the bidirectional threaded rod 141 and slidably mounted inside the two sliding grooves 142 on both sides; a knob 144 is fixedly connected to one end of the bidirectional threaded rod 141, and the ejector component 1... 6 includes an inner recess 161 opened on one side of the mounting frame 123, a pop-out frame 162 inserted inside the inner recess 161, the top of the pop-out frame 162 is inclined, and the pop-out frame 162 and the inner recess 161 are connected by a second spring 163; a pull plate 181 is fixed on the top of the upper plastic plate 18, a T-shaped slot 171 is opened at the bottom of the hanging frame 17, the upper plastic plate 18 and the pull plate 181 are inserted into the T-shaped slot 171, multiple plastic guide posts 182 are fixed at the bottom of the upper plastic plate 18, and multiple plastic holes 131 matching the plastic guide posts 182 are opened through the bottom of the lower plastic frame 13.
[0028] As described above, during the stamping process of the metal sheet metal stamping device, the upper die holder 11 presses down, simultaneously pushing the top inclined surface of the ejector frame 162 to compress the second spring 163 and retract it into the recessed groove 161 without affecting the molding process. The molding guide post 182 of the upper plastic plate 18 is precisely inserted into the molding hole 131 of the lower plastic frame 13 to complete the sheet metal molding. After molding, the upper die holder 11 returns, and the ejector component 16 of the stripper plate 12 pushes the ejector frame 162 out of the recessed groove 161 through the second spring 163 to eject the workpiece, which then slides down the discharge chute 122. The lower plastic frame 13 and the upper plastic plate 18 can be disassembled and replaced with different molding processes. The structure allows the metal support plate 143 to move so that it can support the lower plastic frame 13 without blocking the position of the molding hole 131 of the lower plastic frame 13, allowing the waste material to be discharged from the rectangular unloading groove 121. The support component 14 drives the bidirectional threaded rod 141 to rotate by rotating the knob 144, which drives the two metal support plates 143 to slide synchronously in opposite directions along the slide groove 142 to adjust the support position. This ensures that the bottom of the sheet metal part can be supported during stamping while avoiding the molding hole 131 of the lower plastic frame 13, so that the molding waste material can fall from the molding hole 131 into the rectangular unloading groove 121.
[0029] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
