PURPOSE:To enable the positioning of a contact plate to be surely achieved by a method in which a bearing kit is fitted to a runner ejection plate, and an ejector guide pin is arranged so as to fit to this bearing kit. CONSTITUTION:A bearing kit 31 is composed of a bearing holder, steel balls, a ring spring and a bearing bush. After a case has been formed on a contact plate, a runner ejection pin 14 is projected by lifting a runner ejection plate 6 by an ejector rod 10, and the runner having been formed at the time of forming a case is removed. In this case, since the bearing kit 31 is fitted to the runner ejection plate 6, it slides an ejector guide pin 12 upward similarly to the runner ejection plate 6, and moves it position. Further a molding ejection plate 7 is raised by the ejector rod 10, thereby projecting a molding ejection pin 15 and lifting the contact plate 1 to the side of an upper stationary mold. Consequently, a finger pin 23 is inserted in the positioning hole 1a of the contact plate 1.
