Title: Mold for injection molding of toothed transmission belt
Inventor: HAKODA KEIZO
IPC: B29L29/00
Filed: 1988-12-03
Abstract: PURPOSE:To prevent the disturbance of cord arrangement or the generation of a defect by a method wherein an inner mold is inserted in an outer mold in such a state that cord is wound around the circumference of the inner mold to hermetically close both molds and a molten injection molding material is allowed to flow in the cavity between the molds from a plurality of runners of the outer mold with a small angle of inclination with respect to the cord. CONSTITUTION:When the cross-sectional area of an outer mold 5 crossing the axial direction of said mold at a right angle is made small and the flow of the molding material flowing out to a cavity 6 is throttled, the molding material flows out uniformly along the axial direction of the second runner 7 to flow in parallel to a cord D in the cavity 6 and, therefore, a belt free from the disturbance of cord arrangement is molded. However, in this case, since the air in the cavity 6 can not completely discharged to the outside, a weld line is generated at the confluent part of the molding material. Herein, when the angle theta of inclination of the flow direction of the molding material flowing in the cavity 6 to the cord is set to a specific value or less, air is gradually pushed away downwardly and discharged through the air vent of a lower plate 10 to the outside. This angle theta of inclination is set to the optimum value by the tension of the cord D wound around an inner mold 1.

Abstract: PURPOSE:To prevent a bearing from slipping from a shaft by suspending the inner race of the bearing to the shaft and a collar and press-fitting it. CONSTITUTION:A core 12 formed with a secondary conductor is press-fitted to a shaft 11 to construct a rotor 13, and grooves 14a, 14b are formed circumferentially of the shaft 11 at both sides of the core 12.
