[0025] In order to better understand the purpose, structure and function of the utility model, the following is a further detailed description of a molding device for metal sheet processing of the utility model in conjunction with the accompanying drawings.

[0026] like Figure 1-Figure 3As shown, the utility model is a molding device for processing metal sheets, including a mold base 1 and a top plate 2 arranged above the mold base 1, a stamping groove 13 is arranged on the mold base 1, a groove 14 is arranged below the inside of the stamping groove 13, a slide groove 141 is arranged below the groove 14, an installation cavity 142 is arranged in the mold base 1, a slide cavity 143 is arranged on one side of the mold base 1, and an ejection component 15 for ejecting a sheet is arranged in the installation cavity 142.

[0027] After the stamping is completed, the plate in the stamping groove 13 is pushed upward by the ejection assembly 15 so that the plate is exposed from the stamping groove 13, which facilitates the removal of the plate after the stamping is completed.

[0028] like Figure 2-Figure 5 As shown, four guide rods 11 and a limiting rod 12 are fixedly connected to the upper end of the mold base 1 , and a rubber pad 121 is fixedly connected to the upper end of the limiting rod 12 .

[0029] The ejection assembly 15 includes an ejection plate 151 arranged in the groove 14, the lower end of the ejection plate 151 is fixedly connected to a slide rod 152, a rotating rod 153 is arranged on one side of the slide rod 152, a sliding plate 155 is slidably connected in the sliding cavity 143, a fixed rod 154 is fixedly connected to one side of the upper end of the sliding plate 155, a pull ring 159 is fixedly connected to one end of the sliding plate 155, a connecting plate 157 is fixedly connected to the upper end of the sliding plate 155 near the center position, a spring 158 is fixedly connected to one side of the connecting plate 157, and a limiting block 156 is fixedly connected to the lower part of the inside of the installation cavity 142.

[0030] Rotation grooves are provided at both ends of the rotation rod 153 , and the rotation rod 153 is rotationally connected to the sliding rod 152 and the fixed rod 154 through the rotation grooves.

[0031] The limiting block 156 is provided with a through slot, and the limiting block 156 prevents the sliding plate 155 from sliding and being misplaced through the through slot.

[0032] Four limiting grooves 21 corresponding to the limiting rods 12 are formed on the bottom surface of the top plate 2 .

[0033] In summary: after the top plate 2 is driven downward by the driving source to punch the plate, the limiting rod 12 is inserted into the limiting groove 21 to prevent the punching from being misaligned. After the punching is completed, the sliding plate 155 is pulled out by the pull ring 159, and the fixed rod 154 brought by the sliding plate 155 moves. The sliding plate 155 slides in the through groove on the limiting block 156, and the fixed rod 154 pushes the rotating rod 153. The other end of the rotating rod 153 pushes the sliding rod 152 to rise, and the sliding rod 152 slides in the sliding groove 141. The sliding rod 152 rises and drives the ejection plate 151 to rise. The ejection plate 151 ejects the plate in the stamping groove 13. After taking out the plate, the pull ring 159 is released, and the spring 158 pushes the connecting plate 157 to move. The connecting plate 157 drives the sliding plate 155 to reset. The sliding plate 155 drives the ejection plate 151 to re-enter the groove 14 through the fixed rod 154 and the rotating rod 153 and the sliding rod 152, so that after the plate is stamped, the plate can be quickly taken out without affecting the processing efficiency.
