Title: Manufacture of ink jet head
Inventor: TACHIBANA YOSHIAKI
IPC: B41J2/135
Filed: 1998-08-28
Abstract: PROBLEM TO BE SOLVED: To manufacture an ink jet head using such a die as causing no trouble of breaking a thin pin abutting against the die by performing injection molding after an abutting die comprising a resilient member is abutted against a part of the die where a nozzle hole is made. SOLUTION: A die (pin) 15A for making a nozzle hole is abutted against the forward end of a step hole 9 in an abutting die 7 filled with silicon so that the silicon is compressed slightly. When the silicon is compressed excessively, the pin 15A dives deep into the silicon and the nozzle shape protrudes at the fringe part. When the pin is pushed into the silicon repeatedly, the silicon is damaged by the edge of the pin and cut off. Lifetime of silicon molding can be prolonged by suppressing deformation of the silicon. According to the method, chipping or burring of a nozzle is eliminated and since the pin does not dive into the silicon more than required, resin 14 can be injection molded into a good shape.
