Abstract
A cam mechanism allows a slide ejector plate and slide ejector pins to move relative to a slide core as the slide core moves. Alternatively, the cam mechanism allows the slide ejector plate and the slide ejector pins to move with the slide core. This eliminates the need for a dedicated hydraulic cylinder for moving the slide ejector plate and the slide ejector pins. The number of parts of the die casting device can thus be reduced.
Claims4
A die casting device, comprising:
- a fixed mold that is a part of a mold;
- a movable mold that is another part of the mold, that is configured to be brought into contact with and separated from the fixed mold, and that together with the fixed mold forms a cavity when the movable mold is brought into contact with the fixed mold to allow a molded article to be formed in the cavity;
- a slide core that is provided on the movable mold, that is movable in a direction intersecting with a direction in which the movable mold is moved, and that together with the fixed mold and the movable mold forms the molded article;
- and
- a cam mechanism that allows an ejector member to move relative to the slide core as the slide core moves or that allows the ejector member to move with the slide core, the ejector member being configured to release the molded article from the slide core.
