Problems solved by technology

[0002] Some injection molding products need to directly form screw holes and concave holes, and the two need to be adjacent to each other. However, the existing molds generally only have screw hole forming or concave hole forming, and there is no corresponding mechanism for the molds formed by the two. , during demoulding, after the screw hole is easily separated, the concave hole is still stuck and cannot be separated, so that the product is damaged and becomes a substandard product, and the yield is low

Abstract

The invention discloses an injection mold mechanism with a screw hole and a concave hole, which comprises a rack, wherein an upper support frame is fixed on the top surface of a top plate of the rack;a central through hole is formed in the middle of the top plate of the upper support frame; an upper mold is fixed on the bottom surface of the middle of the top plate of the upper support frame; a central main column body is formed in the top surface of the middle of the upper mold; the central main column body is inserted into the central through hole; and the outer side wall of the central main column body is pressed against the inner side wall of the central through hole. The injection mold mechanism can simultaneously form the screw hole and the concave hole, guarantees steady demolding, achieves a good effect and high yield.

Description

technical field [0001] The invention relates to the technical field of mold equipment, in particular to an injection mold mechanism with screw holes and concave holes. Background technique [0002] Some injection molding products need to directly form screw holes and concave holes, and the two need to be adjacent to each other. However, the existing molds generally only have screw hole forming or concave hole forming, and there is no corresponding mechanism for the molds formed by the two. , in the demoulding process, after the screw hole is easy to break away, the concave hole is also stuck and unable to break away, so that the product is damaged and becomes a substandard product, and the yield rate is low. Contents of the invention [0003] The purpose of the present invention is to address the deficiencies of the prior art, and to provide an injection mold mechanism with screw holes and concave holes, which can realize simultaneous molding of screw holes and concave hol...
