[0043] Preferably, the operator can set a driving motor on one side of the inner sleeve seat, connect the inner sleeve seat with the driving rod of the motor, and drive the inner sleeve seat to rotate by the motor.

[0044] In this embodiment, the operator can place the raw material or blank to be stamped on the corresponding area above the stamping block 8, start the stamping device, and make the upper mold frame 1 move downward along the direction determined by the sleeve rod 2 and the sleeve column 4 under the power driving. At this time, the stamping seat 5 also moves downward, and when the stamping seat 5 contacts the stamping block 8 and the blank, the stamping seat 5 and the stamping block 8 jointly act on the blank to stamp and form the blank into the required shape under the pressure applied by the equipment. The formed workpiece is left in the cavity formed by the inner sleeve seat 7 in the lower mold frame 6.

[0045] Demolding operation:

[0046] After the stamping is completed, the upper die frame 1 is reset to the initial position under the action of the return spring 3 or driven by the equipment. Then the operator holds the handle 13 at both ends of the inside of the demolding cylinder 10, or uses the motor to drive the inner sleeve 14 to rotate the demolding cylinder 10, so that the demolding block 12 is turned into the gap between the molded workpiece and the inner wall of the cavity of the lower die frame 6, the inner sleeve seat 7, etc. The demolding block 12 drives the moving plate 17 to move in the inner sleeve seat 7, so as to push or pry the molded workpiece out of the cavity, thereby achieving demolding.

[0047] After demolding is completed, the demolding cylinder 10 can be rotated in the opposite direction, so that the demolding block 12 is re-turned into the cavity on the upper side of the slide cavity 16, so as to perform the next round of stamping and demolding cycle operation.

[0048] As shown in Figures 1-7 The lower die frame 6, the demolding cylinder 10, and the connecting position of the embedded ring 11 are provided with a slide cavity 16. The lower die frame 6, the demolding cylinder 10, and the embedded ring 11 are connected by sleeve embedding connection and the slide cavity 16. The demolding cylinder 10 and the embedded ring 11 can rotate in the lower die frame 6 through the slide cavity 16. The two demolding blocks 12 are connected to the demolding cylinder 10 by bolt connection. The two ends of the inside of the demolding cylinder 10 are connected to the handle 13 on the front and back sides. The inner sleeve seat 7 is connected to the lower die frame 6 by sleeve embedding connection, and can be removed from the lower die frame 6. The front and back connecting positions of the inner sleeve seat 7 and the lower die frame 6 are provided with an inner cavity. The demolding cylinder 10 and the inner sleeve seat 7 are attached on the upper side. The inside of the upper side of the slide cavity 16 is provided with a cavity that is attached to the volume of the demolding block 12. The demolding block 12 can be turned into the cavity. The two connecting rods 15 are connected to the inner sleeve 14 and the demolding cylinder 10 by bolt connection. The inside of the inner sleeve 14 is provided with a protruding thread. The lower side of the lower die frame 6 is provided with a fixed frame 9, which is connected to the lower die frame 6 by welding connection. The sleeve rod 2 and the sleeve column 4 are connected to the upper die frame 1 and the lower die frame 6 by welding connection. The stamping seat 5 is connected to the upper die frame 1 by bolt connection. The lower side of the stamping seat 5 is provided with a cavity that is consistent with the volume of the stamping block 8. The bottom end of the inner sleeve seat 7 and the connecting position of the stamping block 8 are divided to provide the moving plate 17, which can move up and down in the inner sleeve seat 7.

[0049] Preferably, the operator can place the workpiece in the inner sleeve seat, start the stamping equipment, and stamp the workpiece by cooperating the stamping seat of the upper die frame with the inner sleeve seat of the lower die frame to complete the stamping operation.

[0050] Motor-driven demolding:

[0051] The operator can connect the inner sleeve to the external motor. After the workpiece is completed, the motor is driven to rotate the inner sleeve.

[0052] The rotation of the inner sleeve in turn drives the rotation of the demolding cylinder, so that the demolding block on the demolding cylinder moves in the sliding cavity.

[0053] In addition, the operator can manually hold the handle bar, and drive the demolding cylinder to rotate by rotating the handle bar.

[0054] The subsequent demolding process is consistent with the motor-driven demolding.

[0055] Mold replacement:

[0056] When it is necessary to replace the mold according to different types of stamping workpieces, the stamping seat and the inner sleeve can be disassembled in the upper mold frame and the lower mold frame.

[0057] The operator can first disassemble the old stamping seat and the inner sleeve from the mold frame, and then select and install the appropriate stamping seat and the inner sleeve.

[0058] Demolding principle:

[0059] The inner sleeve is connected with the demolding cylinder through the connecting rod, and the rotation of the inner sleeve drives the rotation of the demolding cylinder.

[0060] The demolding block on the demolding cylinder moves in the sliding cavity, and when it moves to the bottom of the inner sleeve, the shape and position of the demolding block are designed to abut against the moving plate and push the moving plate to rise.

[0061] The moving plate moves upward in the inner sleeve, providing an upward force for the stamped workpiece, so as to push the workpiece out of the inner sleeve and achieve demolding.

[0062] The above only describes the preferred embodiments of the present application, and does not limit the patent range of the present application, and any equivalent structural transformation, direct / indirect application in other related technical fields under the inventive concept of the present application, or the contents of the present application specification and drawings are included in the patent protection range of the present application.
