When injection molding is required, the movable mold is first placed on top of the fixed mold via a lifting mechanism, causing the core at the lower end of the movable mold to engage with the cavity inside the upper end of the fixed mold. At this time, the movable plate inside the cavity moves downwards, causing the telescopic inner column to move downwards. This downward movement of the telescopic inner column, through the connecting ring and connecting rod, drives the movable ring downwards, causing the locking post to engage with the locking hole inside the fixed ring. This allows the protrusion on the outer side of the locking post to engage with the fixed ring. The inner telescopic column is fixed within the groove on the outer wall of the ring. Then, the casting is performed through the casting hole. After the casting is completed and the part is formed, the moving mold is lifted by the lifting mechanism. Then, the worker presses the protrusion inward. At this time, the inner telescopic column is pushed upward by the elastic force of the first spring, which drives the placement plate to lift. Then the part can be taken out. The use of the placement plate, the inner telescopic column, the outer telescopic column and the first spring together enhances the convenience of removing the car air intake grille. The use of the connecting ring, connecting rod, fixed column, moving ring, fixed ring, locking column, second spring, protrusion, locking hole and groove together can restrict the inner telescopic column and prevent it from moving during injection molding, which would affect the quality of the part.
