ABSTRACT:
A center position device for a mold includes an outer housing, and an inner housing. An annular permanent magnet is fitted in the inner housing and covered by a disc secured with washers to close up flat an open lower side of the outer housing. The plural annular magnetic bands are formed in the lower side to be attracted to a mold. The outer housing has a center tubular wall for engaging a sleeve tubular bolt, and a headless tubular bolt engaging in a female threaded hole of the sleeve bolt. A correct pin is fitted in a lower center hole of the headless bolt. A wrench screws the headless bolt to move the correct pin to protrude in an injecting hole of the mold so that after the device is fitted in a threaded rod hole of an injecting machine, the injecting injecting hole of the mold is correctly aligned to the injecting hole of a threaded rod of the machine.
