Abstract
The invention discloses a core-pulling device of an injection mold of a panel having a plurality of inclined holes, comprising an oil cylinder assembly (1), a big slider (2) and a plurality of inclined sliders (6). The piston rod of the oil cylinder assembly (1) is connected with one end of the big slider (2); one end of each inclined slider (6) is respectively connected with the big slider (2), and the axial central lines of each inclined slider (6) and the inclined holes (7.1) in the corresponding cover plate (7) are the same line; the other end of each inclined slider (6) is arranged in the cavity of the injection mold to form the core model of the inclined holes (7); and the big slider (2) and the upper plate of the injection mold are in sliding connection. Thereby, as the inclined sliders (6) at different directions are changed into the up and down movement of the inclined sliders (6) by virtue of the horizontal movement of the big slider (2), the structure is simple. Thereby, the volume of the whole injection mold is reduced.
