Abstract:
A mold includes a fixed mold, a fixture, a movable mold and an ejecting mechanism including a fixture thimble, a nozzle thimble, an auxiliary thimble, an elastic member and a top plate located in ejecting space and having a limit cavity. The nozzle thimble is extended to the molding cavity, and the auxiliary thimble is adjacent to the nozzle thimble. A first end of the fixture thimble is assembled in the limit cavity, and a second end of the fixture thimble is extended to the slider. The elastic member urges the top plate to slide towards a demolding direction. Due to the elastic member, the top plate obtains an elastic force to drive the nozzle thimble and the auxiliary thimble to retreat and separate from the long handle thereby providing a clearance for removing the fixture together with the product and avoiding scratching the product.
