Patent ID: 7438116

Claim:
An aligning-positioning method comprising: preparing a stationary type positioning plate, the positioning plate comprising: an outer side plate having a torus shape in which an outer side plate hole is formed eccentrically of the outer circumference thereof; and an inner side plate having a torus shape in which an inner side plate hole, into which a leading end portion of an extended nozzle mounted on a cylinder leading end portion of a metallic injection molding machine is fitted, is formed eccentrically of the outer circumference thereof; fitting the outer side plate in a stationary die hole formed in a stationary die; fitting the inner side plate in the outer side plate hole of the outer side plate so that there is no clearance between the inner and outer side plate through which a fluid can pass; adjusting an eccentricity of a center of the inner circumference of the inner side plate to a center of the stationary die hole by adjusting the angle made by the eccentric direction between the inner and outer side plates; and adjusting an eccentric direction by turning the inner and outer side plates.
