[0050] With the movable die 1 gradually separating from the fixed die 2, in the process that the movable die 1 drives the reset rod 14 away from the fixed die 2, the locking rod 18 slides along the axis direction of the reset rod 14, but since the end block 16 slides on the fixed die 2, the injection molding module 5 drives the injection product to slide in the direction away from the bundle block 7, in this process, the stripping compression spring 22 restores the deformation and pushes the injection product away from the injection molding module 5 through the stripping strip 20, so as to facilitate the worker to take the injection product.
