Definitions

  • This invention relates in general as part of an injection mold which produces parts requiring details such as internal threads, undercuts, protrusions, or cut-outs.
  • This invention releases the internal ( FIG. 4 thru FIG. 6 ) detail by removing the central pin and collapsing inwardly first the inner sleeve and then the outer sleeve allowing the core sleeves to clear the protruding material (the safety bushing will force this collapse), the part would then be ejected by other means not associated with this apparatus.
  • This invention does not require any rotational motion.
  • the collapsible core is manufactured using two sleeves ( FIG. 7 thru FIG. 14 ), one fit inside the other ( FIG. 1 thru FIG. 3 ), which allows advanced manufacturing techniques resulting in improved quality and reliability.
  • FIG. 1 is a top view of the assembly in molding position.
  • FIG. 2 is a detail view “C” taken from FIG. 1 showing the inside and outside sleeves.
  • FIG. 3 is a section view “A-A” taken from FIG. 1 showing the assembly in molding position cut through both the inside and outside sleeves.
  • FIG. 4 is a top view of the assembly in collapsed position.
  • FIG. 5 is a detail view “D” taken from FIG. 4 showing the inside and out side sleeves.
  • FIG. 6 is a section view “B-B” taken from FIG. 4 showing the assembly in collapsed position cut through both the inside and outside sleeves with the pin removed.
  • FIG. 7 shows the top view of the inner sleeve in molding position.
  • FIG. 8 shows the right side view of the inner sleeve in molding position.
  • FIG. 9 shows the front view of the inner sleeve in molding position.
  • FIG. 10 shows the isometric view of the outer sleeve in molding position.
  • FIG. 11 shows the top view of the outer sleeve in molding position.
  • FIG. 12 shows the right side view of the outer sleeve in molding position.
  • FIG. 13 shows the front view of the outer sleeve in molding position.
  • FIG. 14 shows the isometric view of the outer sleeve in molding position.
  • FIG. 15 shows a isometric image of the assembly in molding position.
  • FIG. 16 shows a isometric image of the assembly in collapsed position.
