| titleOfInvention | Mold apparatus and endless screw manufacturing method |
| abstract | An object of the present invention is to provide a mold apparatus suitable for forming an endless screw having a reciprocating spiral groove having an irregular pitch formed on an inner peripheral surface of a longitudinal cylindrical body. The present invention relates to a mold apparatus (S) for molding an endless screw having a reciprocating spiral groove having an irregular pitch formed on an inner peripheral surface of a longitudinal cylindrical body. The mold apparatus S according to the present invention includes a main shaft insert 10 inserted into the space 41 of the main mold 40 and a first spiral ridge 21 serving as a mold for forming one of the reciprocating spiral grooves. And a second rack portion having a second spiral ridge 31 serving as a mold for forming the other spiral groove of the reciprocating spiral groove. And a nest 30. Each of the first spiral ridge 21 and the second spiral ridge 31 is configured to be extendable and contractible in the longitudinal direction, and can be screwed to the spindle insert 10 in a manner having an irregular pitch.
