Thin-wall plastic part ejection device

Abstract

The invention provides a thin-wall plastic part ejection device. The thin-wall plastic part ejection device comprises an ejection rod, wherein an ejection block is further arranged on the ejection rod; the ejection rod is connected with the ejection block by a screw; the screw is a countersunk screw; the upper surface of the ejection block is circular; the ejection block is asymmetrically distributed relative to the axis of the ejection rod; the circle center of the upper surface of the ejection block is arranged deviating towards a plastic part rib plate; the diameter of the ejection rod is 24mm; and the diameter of the screw is 6mm. According to the design, the ejection block is arranged at the top of the ejection rod so that the ejection area is enlarged and the ejection rod provides great and uniform ejection force; the ejection movement is stable; and an ejection trace is prevented from being formed on the surface of a part.

Description

technical field [0001] The design relates to an ejection device for thin-walled plastic parts, and belongs to the technical field of injection molding machinery. Background technique [0002] Thin-walled plastic parts are generally relatively fragile. When the plastic part is demolded, if the ejector mechanism is not properly set, it is easy to deform the thin-walled part, and sometimes even damage the plastic part, resulting in scrap. How to increase the contact area between the ejector pin and the plastic part is the key to ensure the smooth demoulding of the plastic part. Contents of the invention [0003] According to the above requirements, the purpose of this design is to provide an ejection device for thin-walled plastic parts. By setting a top block on the top of the ejector rod, the ejection area is increased, so that the ejector rod can provide relatively large and uniform ejection force, and the ejection action It is stable and can avoid ejection marks on t...
