Abstract

PURPOSE:To mold the guide member with a rectilinear guide hole positively by giving each wire rod for molding the guide hole tensile force along each center line by the injecting pressure of resin injected and filled into a cavity. CONSTITUTION:Under a condition that a movable die 63 is divided at a parting line P and moved behind, a movable member 34 is moved ahead until it contacts with an inner bottom of a housing concave section 33 of a molding member 31, and fixed at the front position by means of bolts. A supporting member 49 is moved behind almost simultaneously, and a front die plate 52 is fast stuck onto a front surface of the molding member 31. The movable die 63 is moved ahead, and closely attached onto a rear surface of a fixing die 24, and an injection nozzle 26 is intruded into an intrusion concave section 25. Melted synthetic resin is injected primarily into the cavity 55 to increase the filling pressure of injection, continuously injected secondarily and successively injected third. The melted synthetic resin is solidified through cooling under a condition that the pressure is held.
