Definitions

  • a bolt carries a spring and a rotatable anchor block between the bolt head and nut.
  • the bolt is installed to connect two parts by fixing the bolt head to one part so it cannot turn, while the threaded portion of the bolt extends through the second part and carries an anchor block having shoulders whereby the block can be seated in a recess in the second part.
  • FIG. 1 is a fragmentary plan view of a mold and oscillator frame.
  • FIG. 2 is a partially broken away fragmentary elevav tional view of a mold oscillator frame and an oscillator frame support.
  • FIG. 3 is a fragmentary sectional view taken along line III-III of FIG. 2.
  • FIG. 4 is a fragmentary elevational view of the mold oscillator frame in spaced relation from the mold frame support showing the quick change release mechanism in the release position.
  • FIGS. 5, 6, and 7 are fragmentary elevational views of alternative embodiments of my quick change release mechanism.
  • a tubular flow through mold 10 is fixed to an oscillator frame 12.
  • Frame 12 is releasably attached to mold oscillator frame support 14 by my novel quick release means.
  • a pair of parallel upstanding ribs 16 are fixed to a bottom plate 17 of mold oscillator frame 12.
  • a bolt 18 is inserted through a hole 19 in top plate 20 of mold oscillator frame support 14 and fixed thereto by welding or some other convenient means.
  • An anchor block 22 is loosely joumaled on the bolt.
  • the anchor block has shoulders 23 which engage the top of the spaced parallel upstanding ribs 16 when in the secure or attached position.
  • a spring 26 is mounted on the bolt between the anchor block and the top of the frame support and urges the anchor block upwardly at all times.
  • the bolt 18 carries a retaining nut 27 which bears against the top of the anchor block.
  • the nut can be a standard hex nut or, as shown, can be round with small holes around the perimeter of the nut for engagement by a spanner wrench.
  • the nut 27 is turned sufficiently to relieve the clamping pressure on anchor block 22 and spring 26, and to provide sufficient clearance between the shoulders on anchor block 22 and the top of upstanding ribs 16.
  • the block is rotated degrees, bringing the long axis parallel to the ribs, and placing the entire anchor block between the ribs.
  • the oscillator frame 12 is then lifted free of the support 14 byany convenient means such as an overhead crane.
  • the oscillator frame is placed in position over the release nuts and allowed to settle on to the frame.
  • the anchor blocks 22 are each rotated 90 and the nuts 27 are tightened a small amount to move the anchor block downwardly to bear against the upstanding ribs.
  • the heat of bolt 18 is fixed to the top of top plate 20 of the mold oscillator frame.
  • upstanding ribs 16 are eliminated and one or more leaf springs 26A are substituted for coil spring 26.
  • the leaf spring is fixed to the top of top plate 20 and bears against the underside of anchor block 22 in the same manner as the coil spring.
  • the head of bolt 18 is fixed to the underside of top plate 20 by a removable Z-shaped member 30. Member 30 prevents bolt 18 from turning when the nut is being turned, and also retains the bolt in position, yet if the threads of the bolt become stripped or the bolt is otherwise damaged, it can readily be removed for replacement.
  • a recess is provided beneath top plate 20 in which the house coil spring 26.
  • an elongated anchor block loosely journalled on said bolt the length of said block having a longitudinal axis and being greater than the width of the aperture, said block being dimensioned to freely pass through said aperture when its longitudinalaxis coincides with the longitudinal axis of said aperture,
  • said anchor block retaining means comprises a pair of spaced, parallel ribs.
