Injection molding device for machining

The invention discloses an injection molding device for machining, and relates to the technical field of injection molding. The injection molding device comprises a mounting rack, a mounting frame, a mold, an H-shaped sliding rod, an injection molding gun, a motor, an intermittent driving mechanism, a resettable rotating mechanism and an opening and closing assembly. The injection molding device is simple in structure and high in automation degree, in the rotating process of the intermittent driving mechanism, intermittent opening or closing of the mold is realized through the opening and closing assembly, moreover, in the state that the mold is closed, the injection molding gun is driven to move at a constant speed along an injection molding opening of the mold through the resettable rotating mechanism, so that materials in the injection molding gun are injected into the mold at a constant speed, and the problem that the whole mold cannot be filled with the materials completely due to single-hole injection,
