Abstract
In an injection molding machine, a fixed platen 2 is provided with an air cylinder 11 through a bracket 13 and a nozzle touch plate 10 is coupled to an end of a piston rod 12 of the air cylinder 11. The piston rod 12 is extendably and contractedly driven so that the nozzle touch plate 10 is moved forward and backward between a closed position where the tip opening 9a of the nozzle 9 can be closed and a retreated position where the opening 9a can be opened. On the nozzle touch plate 10, a spherical recess portion slightly larger in radius than the tip sphere of the nozzle 9 is formed as an abutment portion 10a, and a heater 14 for adjusting the temperature is disposed in the nozzle touch plate 10. Alternatively, a passage may be formed in the nozzle touch plate 10 so that a medium of an optimum temperature can be circulated and supplied.
