The implementation principle of the embodiment is as follows: during demoulding, the upper die holder 1 moves upwards, a piston rod of the lifting driving piece gradually extends out, the material pressing core 11 is kept tightly pressed against a workpiece, the upper die holder 1 moves upwards to drive the side pressure wedge 12, the third wedge 71 and the fourth wedge 72 to move upwards, the side pressure wedge 12 moves upwards to enable the third side pressure core 61 to be driven by the side pressure resetting piece to be far away from the lower die core 14, and the third side pressure core 61 is firstly separated from the workpiece; then, with the continuous upward movement of the upper die holder 1, the piston rod of the lifting driving piece extends to the longest length, and the material pressing core 11 is separated from the workpiece; at this time, the inclined slope of the lower surface of the third inclined wedge 71 just moves to abut against the third slope 731, the third slider 73 is driven by the third reset piece 732 to move in the direction away from the third side plunger 61 as the upper die holder 1 drives the third inclined wedge 71 to continue to move upwards, the third slider 73 drives the positive lifting block 82 to move, the plane corresponding to the inclined waist of the positive lifting block 82 gradually reaches the bottom of the negative lifting block 81, the third slider 73 continues to move, the negative lifting block 81 gradually moves downwards along the inclined waist of the positive lifting block 82, so that the third movable lower die 62 gradually moves downwards, when the third inclined wedge 71 is disengaged from the third slope 731, the fourth inclined wedge 72 just slides to the fourth slope 631, then as the upper die holder 1 continues to move upwards, the fourth inclined wedge 72 gradually slides relative to the fourth slope, the fourth movable lower die 63 is driven by the fourth reset piece 632 to move obliquely downwards and gradually away from the third side plunger 61, meanwhile, the fourth movable lower die 63 moves to drive the third movable lower die 62 to move together, so that the third movable lower die 62 and the fourth movable lower die 63 move step by step, the workpiece cannot be collided in the moving process of the third movable lower die 62 and the fourth movable lower die 63, the workpiece cannot be deformed by collision, the forming quality of the workpiece in demolding is ensured, the lower die forming surface of the part of the third folded edge 03 of the workpiece integrally moves downwards due to the downward movement of the third movable lower die 62 and the fourth movable lower die 63, the third folded edge 03 of the product cannot wrap the lower die core 14, and the third folded edge 03 is easily separated from the lower die core 14.

Meanwhile, during demolding, the upper die base 1 moves upwards, the piston rod of the lifting driving member gradually extends out, the pressing core 11 is kept to be tightly abutted against the workpiece, the upper die base 1 moves upwards and simultaneously drives the first side pressing core 21 and the second side pressing core 41 to move upwards along the inclined moving direction of the upper die base, so that the first side pressing core 21 and the second side pressing core 41 are firstly separated from the workpiece, then the piston rod of the lifting driving member extends to the longest length along with the continuous upward movement of the upper die base 1, the pressing core 11 is driven to vertically move upwards to be separated from the workpiece, the upper die base 1 continuously moves upwards, the upper die base 1 drives the first inclined wedge 31 and the second inclined wedge 51 to move upwards, the first sliding block 32 is driven by the first resetting member 321 to move towards the direction close to the first inclined wedge 31, the second sliding block 52 is driven by the second resetting member 521 to move towards the direction close to the second inclined wedge 51, and the first sliding block 32 and the second sliding block 52 both drive the self-connected, the first movable lower die 22 is driven by the first lower die resetting piece 221, so that the negative lifting block 81 connected with the first movable lower die 22 gradually descends along the plane where the inclined waist of the positive lifting block 82 is located gradually, the second movable lower die 42 is driven by the second lower die resetting piece 421, so that the negative lifting block 81 connected with the second movable lower die 42 gradually descends along the plane where the inclined waist of the positive lifting block 82 is located gradually, the first movable lower die 22 and the second movable lower die 42 move downwards in an inclined manner towards the direction close to the middle of the lower die core 14 and are far away from a workpiece, the forming surfaces of the outer side positions where the first flanging 01 and the second flanging 02 of the workpiece are abutted against are separated from the workpiece, the part of the workpiece where the first flanging 01 and the second flanging 02 are located cannot completely cover the lower die core 14, and the workpiece is easy to be separated from.

The embodiment of this specific implementation mode is the preferred embodiment of the present invention, not limit according to this the utility model discloses a protection scope, so: all equivalent changes made according to the structure, shape and principle of the utility model are covered within the protection scope of the utility model.
