PURPOSE:To omit exchange work for placing parts by a method wherein the parts are fixed and an injection unit is moved only by a molding pitch section of the parts. CONSTITUTION:Other metallic parts 11 are set to metallic parts 10, these are placed on a fixing jig 4 and a movable jig 5 and metal molds 14 are further placed. A cylinder 33 is let fall, a cope 13 and the metal molds 14 are closely attached and melted resin is injected from a nozzle 12. A cylinder 2 is worked, an injection unit 1 is moved along a slide guide rod 15 only by a molding pitch D previously set, the cylinder 33 is lowered in the same manner as previous operation and the resin is injected to the second molding location. The molding pitch D is measured by means of a limit switch 20, and the movement of the injection unit 1 is controlled by means of a potentiometer 3, an amplfier 6 for controlling the pitch, etc. This method is suitable for the manufacture of parts, etc. for an automobile in which the metallic parts 10, 11 are connected with resin at two locations. |
