Ejection device for plastic mold

Abstract

The invention provides an ejection device for a plastic mold. The ejection device comprises a main supporting rod, a main crossbeam, an auxiliary supporting rod, an auxiliary crossbeam, an ejection air cylinder, a telescopic rod, an ejection rod, a connecting pipe, an ejection seat, U-shaped sliding blocks, a main linear sliding rail, an auxiliary liner sliding rail, a plastic part predetermined track guiding-out wheel structure, bolt nuts, a plastic part guiding-out falling-prevention adjustable plate structure and an angle rotating predetermined adjusting frame. The longitudinal upper end ofthe main supporting rod is mounted on the upper left side of the main crossbeam through a bolt. According to the ejection device for the plastic mold, by arranging main conventional bearings, a mainmounting seat, auxiliary conventional bearings, an auxiliary mounting seat, wheel shafts and guiding-out idler wheels, an plastic part is ejected advantageously according to the predetermined track, the machining efficiency of the plastic part is improved, and manual readjustment is not needed; and by arranging a deep groove ball bearing, a fixing seat, a rotating shaft, a supporting connection seat, an I-shaped liner seat and mounting holes, the guiding-out angle position is rotated advantageously, the guiding-out efficiency of the plastic part is improved, and the operation intensity is reduced.

Description

technical field [0001] The invention belongs to the technical field of plastic moulds, in particular to an ejector device for plastic moulds. Background technique [0002] After the injection molding and cooling of the plastic mold, the plastic parts in the plastic mold need to be ejected. Therefore, an external force is required to push the ejection mechanism inside the mold so that the ejection mechanism can eject the plastic parts that have been injected. However, in the prior art, Most of the work is done through electric cylinders. Due to the poor stability of the connection between the electric cylinder and the mold during work, it will cause deviations when the mold is ejected, which will also affect the deviation when the plastic parts are exported, resulting in plastic parts. Wear and tear, resulting in material waste. [0003] The Chinese patent publication number is CN207327514U, and the name of the invention is a plastic mold ejector device, which includes a mov...
