Corresponding to the left extrusion plate 601 and the right extrusion plate 602, second sliding grooves 606a are respectively formed on the mounting substrate 606. The left extrusion plate 601 and the right extrusion plate 602 respectively penetrate into the two second sliding grooves 606a and are connected to the positive and reverse threaded segments of the second screw rod 608.

The epoxy encapsulant that has completed two extrusion moldings is conveyed to the biscuit forming mechanism 7. The lifting cylinder 704 drives the lifting frame 705 to drive the biscuit mold 701 to descend, and the epoxy encapsulant enters the forming groove 701a at the bottom of the biscuit mold 701 for pressing and forming. Then the extrusion cylinder 706 drives the secondary extrusion plate 702 to extend to perform a further pressing action on the epoxy encapsulant, completing the entire biscuit pressing operation. The finished product continues to be conveyed and slides along the material supporting guide plate 801 into the receiving bin 8 for collection. The subsequent epoxy encapsulants achieve continuous biscuit pressing processing, with a fast production rhythm and high production efficiency.
