Vacuum chuck type insert fixing device for injection mold

The utility model relates to a vacuum chuck type insert fixing device for an injection mold, which belongs to the technical field of injection molding accessory devices, has a simpler integral structure, and is convenient to correspondingly adjust the use position of an adsorption disc main body according to use requirements compared with the prior art, so that the injection mold with a non-smooth surface can be effectively adsorbed, and the service life of the injection mold is prolonged. The injection molds with different specifications can be conveniently adsorbed in the adsorption disc main body, so that the use limitation of the adsorption disc is reduced, and the practicability is relatively good; the two vertical plates are fixedly welded to the base, two sliding columns are fixedly welded between the two vertical plates, and the two sliding columns are slidably sleeved with a mounting table; the adsorption disc body is fixedly welded to the installation table through a plurality of stand columns, four
