How to use the ejector pins?

(2) The ejector pins should be set ineffective parts, such as bone, column, steps, metal inserts, and some thick structural parts. The ejector pins on both sides of the bone and column should be arranged as symmetrically as possible. The distance between the sides of the ejector pins and the bone and column is generally D = 1.5mm. In addition, the centerline of the ejector pins on both sides of the column should be as far as possible to pass through the center of the column.

(3) Avoid setting up ejector pins across steps or on inclined surfaces. The top surface of the ejector pins should be as smooth as possible, and the ejector pins should be arranged at the structural part where the rubber parts are better stressed.

(4) A flat ejector pin should be used when the plastic part is deeper (depth 20mm) or it is difficult to arrange a dome needle. When a flat ejector pin is required, the flat ejector pin should be inserted as much as possible to facilitate processing.

(5) Avoid sharp steel and thin steel, especially the top surface of the ejector pin should not touch the front mold surface.
