The force of the first spring 702 will effectively ensure the sealing of the mold closing between the upper mold 10 and the lower mold 8. The annular connecting block 704 will assist in extracting the gas inside the annular mold cavity through the fixed block 706, the piston 707 and the air inlet 709. At the same time, the upper mold 10 will drive the guide rod 904 to move downward, so that it enters the third cavity 905 and squeezes the sliding plate 902, the push rod 903 and the second spring 901, so that the top of the push rod 903 is flush with the top of the annular mold cavity. After the thermosetting composite raw material is heated and formed, the sliding seat 5, the fixed seat 6 and the guide rod 904 are driven by the cylinder 4 to move upward. At this time, the force of the second spring 901 will drive the sliding plate 902 and the push rod 903 to move upward, and the thermosetting composite material molded part after molding is discharged, which is convenient to use.
