[0014] Technical effects and advantages of the utility model:

[0015] 1. The utility model provides a slide groove in the mold body, and arranges a threaded rod inside the slide groove, and arranges a slide plate and a slider on the rod wall of the threaded rod. The movement of the slide plate drives the convex rod, and the slider drives the air guide rod to move synchronously. When the convex rod moves up to raise the finished product, the air guide rod moves up to drive the trapezoidal nozzle to move up, so that the finished product is dried, and the drying is more comprehensive.

[0016] 2. The utility model sets an air guide hole on the side of the air guide rod. When the air guide rod does not move up, the air guide hole and the connecting groove are staggered. At this time, the wind can only circulate inside the air guide groove. At this time, the dual-purpose fan turns on the cold air to cold-treat the mold groove to accelerate the molding of the mold. After the mold is formed, the air guide rod and the convex rod are synchronously moved up to protrude the mold. At the same time, the air guide hole and the connecting groove are connected. At this time, the dual-purpose fan turns on the hot air and the hot air is ejected through the trapezoidal nozzle to further dry the finished product, thereby saving a lot of drying time.
