Claims

[Claims for Utility Model Registration] A structure of an injection mold including an upper mold, a lower mold, and a core mold connected to the upper mold, comprising: a bore opening in the lower surface of the upper mold; and a core mold connected to the upper mold; a slide member that has been moved, a support means that supports the slide member so as to be movable in the lateral and vertical directions of the mold, a first biasing means that biases the slide member downward; A second side that urges outward in the lateral direction.
and a folded part engaging means protruding from the slide member so as to extend into a portion of the cavity formed between the upper mold and the core mold when the mold is clamped. , a cam surface formed on an inner wall surface of the bore and regulating lateral and vertical movement of the slide member; and a cam driven surface formed on the slide member to engage with the cam surface. An injection mold structure characterized by having.
