摘要： An object of the present invention is to operate an ejector for performing gate cutting and ejection of a molded piece in an injection molding machine at an optimal speed according to a molding purpose. In the present invention, a means for setting an operation speed in gate cutting and a means for setting an operation speed in ejecting a molded piece are provided in a control device for a hydraulic or electric driving means for operating an ejector pin. In accordance with a structure like this, an ejector device is operated during gate cutting by the means for setting an operation speed of the ejector device in gate cutting, and during the subsequent ejection of a molded piece, the ejector device is operated by the means for setting an operation speed for the ejector device in ejecting a molded piece, which is different from that used in gate cutting, whereby a molded piece is ejected from a mold. In addition, when the operation speed of the ejector device in gate cutting becomes relatively high, there is generated no trace of the gate in a molded piece, and when the operating speed of the ejector device in ejecting a molded piece becomes low, there is generated no crack in a molded piece when ejected.
