Secondary forced demolding mechanism for injection mold

The invention relates to an secondary forced demolding mechanism for an injection mold. The secondary forced demolding mechanism for the injection mold comprises a male mold frame, square iron and a lower fixing plate. A first ejector pin plate and a second ejector pin plate are arranged below the male mold frame. A buckling machine device is arranged on the first ejector pin plate and the second ejector pin plate. An outer ring ejector pin is arranged on the first ejector pin plate. An inverted buckling ejector pin is arranged on the second ejector pin plate. The buckling machine device comprises a first mechanical buckle belt, a second mechanical buckle belt, a sliding clamping block, a buckling machine spring and a buckle machine cover plate. According to the secondary forced demolding mechanism for the injection mold, the two ejector pin plates are controlled by the buckling machine device, a product is ejected out of a mold cavity overall firstly, then the inverted buckling ejector pin does not move, the
