Ejection device for bumper mould

The invention discloses an ejection device for a bumper mould. The ejection device for the bumper mould comprises a small straight ejection mechanism, a big straight ejection mechanism, an inclined ejection mechanism and a movable mould insert core (1). Small straight ejection blocks (2) are embedded in big straight ejection blocks (5); inclined ejection blocks (8) are slidably connected with the big straight ejection blocks (5); the lower ends of big straight ejection guide rods (9) are slidably connected into the movable mould insert core (1) through sliding foot components; inclined ejection guide rods (12) are slidably connected with the sliding foot components; small straight ejection guide rods (4) and the big straight ejection blocks (5) are slidably connected in a vertical direction; the lower ends of the small straight ejection guide rods (4) and the big straight ejection blocks (5) are slidably connected with the inclined ejection blocks (8) in a horizontal direction; and return stroke structures for automatically separating the small straight ejection blocks (2) and the big straight ejection blocks (5) are arranged in the sliding components. By adopting the structure, the ejection device for the bumper mould is simple and compact in structure, and can accurately realize each demoulding action without damaging a product.
