Title:
STOPPING DEVICE OF INJECTION UNIT IN INJECTION MOLDER AND VERTICAL INJECTION MOLDER
Document Type and Number:
Japanese Patent JP3211733
Kind Code:
B2
Abstract:

PROBLEM TO BE SOLVED: To facilitate the adjusting work at the changing of nozzles different in lengths.
SOLUTION: When an injection unit 7 is lowered, at the final stage of its lowering, a detecting switch 12 is actuated by a stopper 11, which also serves as a dog, resulting in outputting a detection signal. By this outputted signal, the lowering speed of the injection unit 7 is lowered and, just after that, by abutting the abutting part 9b of the injection unit 7 against the stopper 11, the injection unit 7 is stopped under the state that a nozzle 6 is urged against a mold 3. Since the stopper 11 also serves as the dog of the detecting switch 12, no dog is necessary to be provided as an extramember. Further, when a nozzle having a length different from that of the existing nozzle is changed, the adjustment for the changed nozzle is only the adjustment of the position of the stopper 11 in response to the length of the changed nozzle.
