When the column moves to the limit groove and the limit block are at the same horizontal height, the ejection plate moves downward until it matches the reserved opening at the bottom of the mold. The limit block is not squeezed by external force. When the second spring is free from external force, it uses its own reset elastic force to drive the limit block to insert into the limit groove to limit the position of the column. When the driving component is started to drive the punch head to punch the sheet metal, the extrusion rod moves downward to squeeze the extension plate. At this time, the extension plate drives the column to move downward, the limit block is separated from the inside of the limit groove, the column is separated from the limit, and the convex block squeezes the limit block, so that the limit block is away from the limit groove. When the punch head is reset, the extrusion rod is separated from the extrusion of the extension plate, and the first spring is reset to drive the ejection plate to eject the sheet metal through the column, thereby achieving the effect of rapid material removal.

[0015] (2) The utility model moves the torsion spring rod, which moves inside the slide rail and uses the connecting arm to drive the clamping plate to disengage from the clamping of the mold. When the clamping plate is not subjected to external force, the torsion spring rod drives the clamping plate to change from a vertical state to a horizontal state, and the mold can be replaced at this time.

[0025] The extrusion rod 76 is located directly above the slot 75 , and the slot 75 is located above the extension plate 74 . The transverse cross-sectional dimension of the extrusion rod 76 is the same as the transverse cross-sectional dimension of the slot 75 .

[0026] The squeezing rod 76 passes through the slot 75 to squeeze the extension plate 74, thereby driving the column 72 to move downward.

[0027] The shape of the protrusion 78 is semicircular, and the protrusion 78 is located directly above the limiting groove 77 .

[0028] Through the protrusion 78 , when the column 72 moves downward, the protrusion 78 will squeeze the limiting block 711 to make it further away from the limiting groove 77 .
