Driver pin on injection molding tool for connection between tool plates comprises an elastic sleeve radially expanded by a screw in conjunction with compression members

摘要

One tool plate (3) has an opening (19) for receiving the driving pin (8) so that the plate can be moved relative to another tool plate (2). One tool plate (3) has an opening (19) for receiving the driving pin (8) so that the plate can be moved relative to another tool plate (2). The driving pin has an elastic sleeve (10) which extends over the entire length and can be radially expanded against the wall (20) of the opening. Expansion is produced by tightening a screw (11) to press the sleeve against solid compression members (12,13). The screw also holds the sleeve on a mounting area (9). An independent claim is made for a driving pin with spreading and mounting areas for connecting the plates of an injection molding tool.
