Abstract
A mold includes upper and lower mold members, an upper-side slider pushing member, a slider, and an ejector rod. The upper-side slider pushing member is secured on the upper mold member. The lower mold member defines a movement space. The slider is slidably mounted on the lower mold member, and forms outer and inner angled surfaces. The ejector rod is movably mounted on the lower mold member. The ejector rod extends into the movement space and is driven by the push bar. The ejector rod and the upper-side slider pushing member are respectively engageable and thus pushing the inner and outer angled surfaces of the slider to cause the slider to slide on the lower mold member. The mold keeps the slider in a closed state while the mold is being opened, thereby preventing molded products from sticking to an upper mold member and saving internal space for the sliders.
