Die casting device and molding method

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, wherein the cam mechanism includes
• a cam slot provided in the slide core, and
• a lock pin that is movable via a tracing portion inserted in the cam slot, that is engaged with the ejector member and is engageable with an engaged portion of the movable mold, and that allows the ejector member to move relative to the slide core when engaged with the engaged portion, and allows the ejector member to move with the slide core when disengaged from the engaged portion.
