Abstract
An injection station of an injection blow molding machine and a method for forming parisons and molded articles. The injection station includes a die plate with a keyway formed through a least a portion of a surface of the die plate. The keyway separates front and back portions of the surface of the die plate. The injection station further includes a resin injection tooling comprising a draw bar, with at least a portion of the draw bar operable to be positioned within the keyway of the die plate, a base plate secured to a back side of the draw bar and operable to be secured to the back portion of the surface of the die plate and, and a manifold secured to a top of the base plate, with the manifold being configured to discharge resin into cavities to form the parisons.
Claims18
An injection station of an injection blow molding machine, said injection station being configured for injecting a resin into mold cavities to form parisons, said injection station comprising:
- a die plate with a keyway formed through a least a portion of a surface of said die plate, wherein said keyway separates front and back portions of the surface of said die plate;
- a draw bar, with at least a portion of said draw bar positioned within said keyway of said die plate;
- a base plate secured to the back portion of the surface of said die plate and to a back side of said draw bar;
- and
- a manifold secured to a top of said base plate, wherein the manifold is configured to discharge resin into the cavities to form the parisons.
A resin injection tooling for attachment to at least one die plate associated with an injection blow molding machine, with said resin injection tooling being configured to inject a resin into mold cavities to form parisons, said resin injection tooling comprising:
- a base plate configured to be secured to a top surface of the die plate,
- wherein said base plate includes a main section and a plurality of projections extending rearward from said main section;
- and
- a manifold secured to a top of said base plate, wherein said manifold is configured to discharge resin into the cavities to form the parisons.
