[0035] (2) The first return spring provides an external pulling force to the lower die enclosure block, so that the lower die enclosure block can automatically move outward, and the downward movement of the pressing block can provide an extrusion force to the lower die enclosure block, so that the lower die enclosure block can automatically move. When the mold is subsequently opened, the lower die enclosure block automatically moves outward, thereby improving the convenience of using the equipment.

[0036] (3) The product can be lifted from the lower mold body by moving the top block upward, so that its bottom and the mold body are separated, thereby realizing demolding of the product. The movement of the top block is controlled by the movement of the lower mold enclosure block, thereby realizing automatic control of the top.

[0037] (4) The downward movement of the blocking block can reduce the adhesion between the bottom of the product and the mold body. After the blocking block is moved downward, the bottom of the product can be blown through the connecting groove, which is convenient for heat dissipation around the product and can also assist in demolding the product.

[0038] (5) The opening of the heat dissipation channel can be blocked by the baffle, so that the airflow of the heat dissipation channel is blown upward through the connecting groove and the ventilation groove, cooling the side of the product, which can quickly reduce the surface temperature of the product and facilitate the subsequent removal of the product.
