PURPOSE:To position an injection nozzle easily at a high accuracy by installing a positioning sensor on a mold and an injection nozzle and moving the injection nozzle by a cylinder. CONSTITUTION:A positioning cylinder 7 for an injection nozzle 2 is installed and, as an example, a sensor consisting of a photoelectron tube 8a for confirming position on the injection nozzle and a mold 1. After setting the mold 1 on the press, the injection nozzle 2 is moved by driving cylinders 6 and 7 close to an inlet 1a at the bottom of mold 1. At that time, the photoelectron tube switch 8a installed close to the inlet 1a and a photoelectron tube switch 8b set on the injection nozzle 2 face and sense each other and send a signal to a display section 9, informing the operator that the inlet 1a and the injection nozzle 2 are accurately consistent with. |
