The lower end of the push rod 15 is fixedly connected to a limit rod 16. A limit ring 17 is movably sleeved on the outer wall of the limit rod 16. The limit ring 17 is arranged in a strip shape. When stamping a sheet, the sheet is placed on the punch 2. After the mold is opened, if the molded part is attached to the outer wall of the punch 2, the limit ring 17 can be driven to rise, driving the limit rod 16 to move upward, so that the push rod 15 pushes the rotating plate 14 upward. When the rotating plate 14 is deflected, air is filled between the punch 2 and the molded part, reducing the generation of negative pressure and facilitating demoulding.

[0020] A lifting mechanism is provided on the lower side of the limiting ring 17, and the lifting mechanism includes a notch three 18 symmetrically opened on the punch 2, the notch three 18 is the entrance for outside air to enter the inside of the punch 2, the top wall of the notch three 18 is fixedly connected with a support frame two 19, and a vertical cylinder 20 is fixedly inserted in the middle of the support frame two 19, and the driving end of the cylinder 20 is fixedly connected to the limiting ring 17. The cylinder 20 keeps the rotating plate two 14 engaged with the notch one before the mold is closed. After the mold is opened, if the molded part is wrapped on the punch 2, the limiting ring 17 is driven to rise, so that the rotating plate two 14 is deflected to lift the molded part.

[0021] A die 4 matching the punch 2 is arranged on the upper side of the punch 2, and two symmetrically arranged slots 5 are provided on the upper side wall of the slot 25, a fixed shaft 6 is fixedly inserted into the inner side wall of the slot 25, the fixed shaft 6 is close to the adjacent ends of the two slots 25, a movable sleeve on the outer wall of the fixed shaft 6 is provided with a rotating plate 7 located in the slot 25, a rotating seat 8 is fixedly arranged on the upper side wall of the rotating plate 7, a connecting plate 9 is rotatably connected to the rotating seat 8, and the end of the connecting plate 9 can be deflected left and right along the rotating seat 8, and a supporting mechanism is arranged on the rear side of the die 4.

[0022] The supporting mechanism includes a supporting frame 10 fixedly connected to the rear side wall of the bottom plate 1, the supporting frame 10 is vertically upwardly arranged, the upper end of the supporting frame 10 is fixedly connected with a hydraulic cylinder 11 vertically downwardly, the hydraulic cylinder 11 is located on the upper side of the die 4, the driving end of the hydraulic cylinder 11 is fixedly connected with a connecting plate 2 12, the connecting plate 2 12 is rotatably connected with the connecting plate 9, under the action of gravity, the die 4 is suspended on the rotating plate 7 through the fixed shaft 6, so that the notch 2 5 is naturally opened, when the plate is placed on the punch 2, the hydraulic cylinder 11 is started to descend, after the die 4 contacts the plate, as the connecting plate 2 12 descends, the rotating plate 7 is gradually pressed with the notch 2 5 under the push of the connecting plate 9, and finally drives the die 4 to move downward, and completes the mold closing with the punch 2, at this time the edge material is pressed on the upper side of the baffle 3.

[0023] The grooves 1 and 2 are both provided with stepped platforms, which are respectively located at the lower sides of the rotating plates 1 7 and the 2nd rotating plates 14 to play a supporting role. The bottom plate 1 is fixedly provided with a plurality of support rods 21 located at the outer side of the baffle plate 3. The ends of the support rods 21 are fixedly connected with a horizontal unloading ring 22. The unloading ring 22 is sleeved on the outer side of the die 4, and the unloading ring 22 does not contact the outer wall of the die 4. When the mold is opened, the hydraulic cylinder 11 drives the connecting plate 2 12 to move upward. Under the linkage of the connecting plate 1 9, the rotating plate 1 7 is first deflected upward to open the groove 2 5, and the air contacts the upper side wall of the molded part. Then, as the connecting plate 2 12 rises, the rotating plate 1 7 will lift the die 4. If the molded part is stuck in the die 4, when the die 4 passes through the unloading ring 22, the unloading ring 22 blocks the edge material. At the same time, the groove 2 5 is in an open state, which reduces the generation of negative pressure in the die 4 and makes it easy to demold the molded part.

[0024] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
