摘要:
In various embodiments, a molded product delivery apparatus or a blow molding machine includes first transfer member that includes first paired chucks that hold a portion of an outer wall of a neck portion of a molded product, and a second transfer member that includes second paired chucks that hold another portion of the outer wall of the neck portion of the molded product. From a state where the molded product is held by both of the first paired chucks and the second paired chucks simultaneously, by opening one of the first paired chucks and the second paired chucks without interfering with the other, the molded product is delivered between the first paired chucks and the second paired chucks.

An object of the invention is to provide a molded product delivery apparatus capable of delivering a molded product without using a flange support structure limited to erected transfer or an inverted support pin limited to inverted transfer.A first transfer member (720) includes first paired chucks (720A, 720B) that hold a portion of an outer wall of a neck portion (2A) of a molded product 2, and a second transfer member (411) includes second paired chucks (412) that hold another portion of the outer wall of the neck portion (2A) of the molded product (2). From a state where the molded product (2) is held by both of the first paired chucks (720A, 720B) and the second paired chucks (412) simultaneously, by opening one of the first paired chucks (720A, 720B) and the second paired chucks (412) without interfering with the other, the molded product (2) is delivered between the first paired chucks (720A, 720B) and the second paired chucks (412).
摘要:
Plastic container manufacturing plant comprising devices for injection-compression of plastic in moulds and effected by means of at least one rotary carousel actuated by electro-pneumatic actuators, of the single-stage type integrating at least one first rotary carousel (2) for moulding of the preforms and a second rotary carousel (7) for stretch blow moulding of the preforms. Moreover, the plant comprises a transport system (5) between said first (2) and second rotary carousel (7) comprising further handling wheels, of which at least one (8) comprises means for thermal conditioning of the preforms.
摘要:
An injection blow molding machine having an injection molding rotor including a plurality of injection molding units with individual split mold cavities for preforms, a transfer rotor, a blow molding rotor including a plurality of blow molds, and a removal rotor, essentially within a shared operating plane, and split mobile neck molding parts which fit into each blow mold and each mold cavity and which are transferred with a preform and removed with a stretch-blown bottle from the blow mold. In the process, each preform is transferred in the neck molding part into the blow mold.
摘要:
A blow moulding machine for blow moulding a container having an integrally formed handle; said container blow moulded from a previously injection moulded preform; said preform comprising a body portion and said integrally formed handle; said machine including a preform loading station at which said preform is oriented by a preform orienting apparatus.
摘要:
An injection blow molding device in which a lip mold is formed in different shapes for an injection mold and a blow mold. Mold clamping surfaces corresponding to the different shapes are formed on the injection mold and the blow mold, respectively, to prevent an air leakage from the blow mold. An upper portion of an outside surface of the lip mold which contacts the mold is formed in a tapered surface whereas a lower end portion of the outside surface is formed in a vertical surface. The upper portion and the lower portion of a surface contacting the lip mold, of each of the injection mold and the blow mold are formed respectively in a tapered surface and a vertical surface that correspond to the tapered surface and the vertical surface of the outside surface of the lip mold. Clamping the lip mold in the injection mold is performed at the tapered surface of the upper portion and clamping the lip mold in the blow mold is performed at the vertical surface of the lower end portion.
