摘要： 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.

摘要： An injection blow molding (IBM) system and method for forming a plurality of parisons and molded articles. The IBM system includes an injection station having upper and lower die sets and a plurality of upper and lower mold half blocks each attached to a respective die set. Each of the upper mold half blocks has a corresponding lower mold half block with which it cooperatively defines one or more cavities for forming the exterior shape of the body of one or more of the parisons. The individual, independent attachment of the mold half blocks to the die sets allows easy individual replacement of faulty or worn mold blocks. Further, such an independent attachment configuration also permits the mold half blocks of each die set to be spaced from one another, so as to reduce thermal expansion problems and ease dimensional tolerances required for the width of the mold half blocks.

摘要： An injection blow molding (IBM) system and method for consistently maintaining the surface temperature of the parison molds within a desired range. Implementation of this system/method can result in more consistent production of higher quality parisons and molded articles. Additionally, this system/method reduces the discretion required by the IBM operator and shifts the burden of consistently making high-quality parisons and molded articles onto the designer of the IBM tooling.

摘要： An injection nozzle that can be used in an injection blow molding system without use of an external heat source comprises a two-piece structure broadly including a structural outer body for coupling the nozzle to a resin manifold and a thermally conductive insert. At least a portion of an axial length of the insert has an outer diameter that is less than an inner diameter of a coinciding coaxial portion of the outer body, such that the differences in the inner and outer diameters present an insulating air gap along at least a portion of the nozzle length. A sufficient operating temperature for hot melt resin can then be obtained without use of the external heat source.

摘要： Injection molding apparatus has upper and lower mold halves that split along the center line of the parison cavity and the gate passage leading thereto. Each hot melt injection nozzle is received within a tubular insert cup having a reduced diameter tip that is seated within the gate passage. The cup is supported on the lower mold half so as to remain thereon as the upper mold half opens and closes the mold. The base end of each nozzle has a swivel ball and socket relationship with the manifold block which supplies it with hot melt, while the tip end of each injection nozzle is configured to permit swivelling within the insert cup as need be to accommodate dimensional changes that arise during non-uniform thermal expansion and contraction of different parts of the tooling.

摘要： The conditioning station of an injection stretch blow mold machine is provided with a heater ring for each hot, soft preform presented to the station. The heater ring emits infrared light waves that are confined to the transition region of the preform between the neck and main body portions to pin-point the addition of heat to the transition region.

摘要： Quick change blow mold tooling includes a pair of mold cavity blocks that cooperate to define a series of blow cavities. The tooling further includes a pushup plate having a series of bottom contours that plug the otherwise open bottoms of the cavities when the pushup plate is against the bottom of the mold blocks. Each mold block is quickly attached to and detached from its supporting back plate using studs that fit into receiving holes on the back plate and cam locking shafts that are accessible from opposite side edges of the back plates. The back plates thus remain secured to platens of the bottle forming machine during change out of the tooling. Similarly, the push up plate has a pair of locking studs projecting from the underside thereof that are received within socket members attached to the machine. The socket members are provided with quick release threaded couplers that can be locked and unlocked by hand.

摘要： Auxiliary end heating devices on an elongated, heated hot melt distribution manifold body assist in maintaining uniform temperatures throughout all portions and passageways of the manifold body. The heating devices preferably take the form of thick film electrical resistive heaters of plate-like construction. The end heaters are on their own control circuit separate and apart from the circuit for other heaters for remaining portions of the manifold body. Special isolating slots are formed in lower corners of the manifold body between supporting standoffs and overhead melt passageways in the manifold body.
