Title:
MUTUAL CONNECTION OF MEMBERS BY INJECTION MOLDING AND APPARATUS THEREFOR
Document Type and Number:
Japanese Patent JP3173380
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To prevent the fixing inferiority caused by the shrinkage of a resin generated when members are mutually connected by charging or pouring the resin in the fixing hole bored in a connection part by employing injection molding in the molding of a fixing member due to the filling with the resin.
SOLUTION: Holes 3, 4, 4a having a required shape becoming a series of fixing holes 5 are bored in the connection parts 1a, 2a of a main member 1 and a connection member 2 and the positions of the holes 3, 4, 4a are aligned to superpose the connection parts 1a, 2a of the main member 1 and the connection member 2 one upon another to form fixing holes 5. The connection parts 1a, 2a are held between an arranging jig 10 and a nozzle leading end surface to close one opening ends of the fixing holes 5 by the arranging jig 10. Nozzle orifices are brought into contact with the opening ends of the fixing holes 5. A molten resin 12 is injected and charged in the fixing holes 5 in such a state that the connection parts 1a, 2a are pressed by nozzle touch force to be dwelled and the main member 1 and the connection member 2 are integrally connected by the fixing member 14 of the resin molded by cooling and solidification.
