Definitions

  • the present invention generally relates to, but is not limited to, molding systems, and more specifically the present invention relates to, but is not limited to, a linking member and a method of use thereof.
  • Molding is a process by virtue of which a molded article can be formed from molding material by using a molding system.
  • Various molded articles can be formed by using the molding process, such as an injection molding process.
  • a molded article that can be formed, for example, from polyethylene terephthalate (PET) material is a preform that is capable of being subsequently blown into a beverage container, such as, a bottle and the like.
  • a typical molding system includes an injection unit, a molding machine and a mold assembly.
  • the injection unit can be of a reciprocating screw type or of a two-stage type.
  • the molding machine includes inter alia a frame, a movable platen, a fixed platen and an actuator for moving the movable platen and to apply tonnage to the mold assembly arranged between the platens.
  • the mold assembly includes inter alia a cold half and a hot half.
  • the hot half is usually associated with one or more cavities (and, hence, also sometimes referred to by those of skill in the art as a "cavity half), while the cold half is usually associated with one or more cores (and, hence, also sometimes referred to by those of skill in the art as a "core half).
  • the one or more cavities together with one or more cores define, in use, one or more molding cavities.
  • the hot half can also be associated with a melt distribution system (also referred to sometimes by those of skill in the art as a "hot runner") for melt distribution.
  • the mold assembly can be associated with a number of additional components, such as neck rings, neck ring slides, ejector structures, wear pads, etc.
  • injection molding of PET material involves heating the PET material (ex. PET pellets, PEN powder, PLA, etc.) to a homogeneous molten state and injecting, under pressure, the so-melted PET material into the one or more molding cavities defined, at least in part, by the aforementioned one or more cavities and one or more cores mounted respectively on a cavity plate and a core plate of the mold assembly.
  • the cavity plate and the core plate are urged together and are held together by clamp force, the clamp force being sufficient enough to keep the cavity and the core pieces together against the pressure of the injected PET material.
  • the molding cavity has a l shape that substantially corresponds to a final cold-state shape of the molded article to be molded.
  • the so-injected PET material is then cooled to a temperature sufficient to enable ejection of the so- formed molded article from the mold.
  • the molded article shrinks inside of the molding cavity and, as such, when the cavity and core plates are urged apart, the molded article tends to remain associated with the core piece. Accordingly, by urging the core plate away from the cavity plate, the molded article can be demolded, i.e. ejected off of the core piece.
  • Ejection structures are known to assist in removing the molded articles from the core halves. Examples of the ejection structures include stripper plates, ejector pins, etc.
  • the neck region includes (i) threads (or other suitable structure) for accepting and retaining a closure assembly (ex. a bottle cap), and (ii) an anti-pilferage assembly to cooperate, for example, with the closure assembly to indicate whether the end product (i.e. the beverage container that has been filled with a beverage and shipped to a store) has been tampered with in any way.
  • the neck region may comprise other additional elements used for various purposes, for example, to cooperate with parts of the molding system (ex. a support ledge, etc.).
  • the neck region can not be easily formed by using the cavity and core halves.
  • split mold inserts sometimes referred to by those skilled in the art as "neck rings” have been used to form the neck region.
  • a first neck ring half 102a and a second neck ring half 102b cooperate to form the neck region of the preform.
  • a first neck ring half 103a and a second neck ring half 103b (jointly referred to herein below as a "neck ring pair 103"), which can be substantially similar to the first neck ring half 102a and the second neck ring half 102b.

  • the neck ring pair 102 can be thought of as a "previous neck ring pair” and the neck ring pair 103 can be thought of as a "subsequent neck ring pair", the terms “previous” and “subsequent” referring to an order in which they are placed on the respective first slide 104a or the second slide 104b.
  • the first slide 104a and other first slides 104a potentially present in a mold are linked together for movement is substantial unison, for example, by means of a first set of connecting bars (not depicted).
  • the second slide 104b and other second slides 104b potentially present in the mold are linked together for movement is substantial unison, for example, by means of a second set of connecting bars (not depicted).
  • a first cam system can be used to control the lateral movement of the plurality of first neck ring halves 102a along an axis "B" via the first set of connecting bars.
  • a second cam system can be used to control the lateral movement of the plurality of second neck ring halves 102b into an opposite direction along the axis "B" relative to the first neck ring halves 102a via the second set of connecting bars.
  • a single cam system can be used to control lateral movement of both the first and the second neck ring halves 102a, 102b relative to each other, for example, by means of a mechanical linkage between the first and second sets of connecting bars.
  • Other types of actuators can also be used to effect the lateral movement of the first and the second neck ring halves 102a, 102b (for example, but not limited to, a servo motor and the like).
  • a typical first slide 104a (as well as the second slide 104b) comprises a positioning interface 106, a coupling interface 108 and a cooling interface 110.
  • the positioning interface 106 comprises two spring pin receptacles that cooperate with two spring pins (not depicted) associated with the first neck ring half 102a.
  • the first neck ring half 102a comprises a corresponding positioning interface (not depicted), which can also comprise two spring pin receptacles, that cooperate with the two spring pins.

  • the cooling interface 110 is used to supply coolant (such as water, etc.) from a source of coolant (not depicted) to the first neck ring half 102a.
  • a technician (or another representative of an entity managing a molding system that includes the neck rings and the slides or an entity of servicing the molding system), first positions the first neck ring half 102a relative to the first slide 104a and the second neck ring half 102b to the second slide 104b. This can be done, for example, by using the aforementioned spring pin and spring pin receptacle.
  • the corresponding positioning interface on the first neck ring half 102a is associated with some degree of clearance and, as such, allows certain degree of shift to the first neck ring half 102a relative to the first slide 104a and to the second neck ring half 102b relative to the second slide 104b.
  • the first neck ring half 102a is then secured to the first slide 104a and the second neck ring half 102b is then secured to the second slide 104b using the aforementioned fasteners and the coupling interface 108 and the complementary coupling interface 112.
  • a typical procedure may include finger- tightening of the fastener(s) until a pair of respective O-ring (not depicted) placed between the first neck ring half 102a and the first slide 104a and the second neck ring half 102b and the second slide 104b is compressed and then torquing them to a pre-determined degree.
