By providing a molding mechanism 4, the cutter 45 is pressed and cut on the rubber sheet, thereby realizing the molding of multiple groups of rubber gaskets, and by providing a limiting assembly 46, the cutter 45 is limited on the rubber sheet before pressing and cutting the rubber sheet, so as to avoid the rubber sheet from being offset and improve the processing quality. At the same time, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0032] During operation, firstly, the screw rod 32 is rotated to make the transmission plate 331, the positioning roller 34 and the moving block 332 slide downward synchronously, and the moving block 332 slides inside the positioning plate 31, so that the positioning roller 34 fits with the top of the rubber sheet placed on the top of the workbench 1.
