[0043] The implementation principle of the mold for aseptic medical packaging blister molding in the embodiment of the present application is as follows: when it is necessary to blister a plastic sheet, first place the plastic sheet on the lower mold 15, then start the demoulding motor 21, the demoulding motor 21 drives the demoulding frame 25 to move downward, and the demoulding frame 25 drives the control block 56 to move downward, when the control block 56 contacts the plastic sheet, the demoulding frame 25 continues to move, so that the control block 56 is retracted into the control groove 251, and when the switch moving piece 57 contacts the switch fixed piece 58, the demoulding frame 25 contacts the plastic sheet to fix the plastic sheet, and the storage The battery 51 energizes the electromagnet 52 and the vacuum cleaner motor 351, and the electromagnet 52 drives the demoulding motor 21 to move. When the first gear 211 and the second gear 221 are separated, the first gear 211 and the third gear 411 are engaged, and the demoulding motor 21 drives the brush 34 and the second vacuum tube 355 to move. The brush 34 cleans the dust on the surface of the plastic sheet, and the vacuum cleaner motor 351 absorbs the dust on the surface of the plastic sheet and the dust in the vacuum mold cavity. At the same time, the second vacuum tube 355 moves to increase the suction range of the second vacuum tube 355.

[0044] Then, the demoulding motor 21 is turned off, and the electric cylinder 13 is started. The electric cylinder 13 drives the upper mold 14 to contact the plastic sheet to perform vacuum forming on the plastic sheet. The upper mold 14 drives the L-shaped separation rod 142 to move. When the L-shaped separation rod 142 contacts the separation slope 591, the upper mold 14 continues to move. The L-shaped separation rod 142 pushes the separation block 59 to move. The separation block 59 drives the switch stator 58 to move. When the switch stator 58 is separated from the switch movable plate 57, the locking mechanism 7 locks the separation block 59, and the demoulding motor 21 returns to the initial position. At the same time, the upper mold 14 contacts the plastic sheet. When the demoulding motor 21 is started to reverse, the demoulding frame 25 can return to the initial position to facilitate continued use next time.

[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
