A quick-change structure of an injection mold

Abstract

The utility model provides a kind of injection mold quick-change structure, including lower die holder, upper die holder, fixed assembly and linkage assembly. By being placed in the fixed groove on lower die holder with lower mould, upper mould is placed on the upper end of lower mould in correspondence, then control injection molding machine drives upper die holder to descend, and upper die holder descends can make upper mould be placed in the fixed groove of upper die holder, then drive two groups of driving pieces synchronous rotation by linkage assembly, and two groups of driving pieces synchronous rotation can drive two groups of clamping plates in two groups of fixed grooves relative close mobile clamping and fixing lower mould and upper mould, or relative far away mobile release the clamping and fixing of lower mould and upper mould, to facilitate the simultaneous fixing or releasing of lower mould and upper mould, improve the replacement efficiency of injection mold.
