Definitions

  • ABSTRACT A latch and release mechanism for predetermined, timed separating movement of a plurality of plate members relative to each other, which includes a longitudinal latch bar secured to one plate member and lockingly engagable by a rotatable detent which is spring biased in locking position; and a longitudinal release bar secured to another plate member which is movable relative to the one plate member; both bars are arranged in parallel overlying alignment and said release bar is provided with at least one cam surface adapted to move said rotatable detent member out of engagement with said latch bar when said another plate member is moved away from said one plate member; the rotatable detent 'is supported within a third plate member; the arrangement is such that in one position of said latch and release mechanism independent movement of said another plate member relative to said one and said third plate member is permitted and in the release position of said latch and release mechanism the third plate member is caused to move conjointly with said another plate member relative tos
  • the present invention relates to a positive selflocking and releasing mechanism for a multiple .plate structure in which the individual plate members are required to be moved relative to each other, individually and conjointly.
  • the present invention is particularly adaptable to a multiple plate die and mold assembly, as for instance in injection molding apparatuses, and in which the die and mold assembly is composed of of-one plurality of super-imposed die plates.
  • AT least one plate ofgroup of die plates is separately movable with respect to another plate of the same group and a second group of die plates. In another position of the die assembly, conjoint movement of said one die plates and said another die plate of said one group of plates relative to plates is provided.
  • the improved self-locking and release mechanism is incorporated in a structure involving at least three members movable in succession separately and conjointly and relative to one another and in timed, predetermined sequence and within predetermined limits of movement.
  • the improved self-locking and release mechanism is comprised of a latch secured to one member which is engagable in locking position by a spring loaded detent secured to a second member, and a releasing cam secured to a third member adapted to cam the detent out of locking engagement with said latch of said first member upon movement of the third member relative to the first and second member along a predetermined distance.
  • the third and second member are caused to move conjointly with respect to the first member; the second and third member being cooperatively connected by means of a loss-motion connection having a predetermined magnitude of free movement corresponding to the free movement of the releasing cam before striking the detent.

  • FIG. 5 is a longitudinal cross-section through the present improved self-locking and release mechanism as seen in the direction of the arrows 5-5, in FIG. 4.
  • FIGS. 1 to 3 there is illustrated, for example, a multiple plate die and mold structure, generally indicated by the numeral 10, as utilized in an injection molding apparatus.
  • Multiple die and mold structure 10 in the illustrated instance, is comprised of a lower die assembly 12, usually rigidly supported on base members 14, and an upper die assembly 16 adapted for movement relative to lower die assembly 12 between a closed and an open position; the parting line between the die assemblies being indicated at 18 lying in a plane normal to the movement of upper die assembly 16 relative to lower die assembly 12.
