Embodiment Construction

[0044] refer to figure 1 , represents an injection mold (2) according to a first embodiment of the invention for injection molding parisons, for example from polyester, in particular polyethylene terephthalate (PET), the The parison is used for later blow molding to form the container. The injection material to be molded is injected through the feed nozzle (4) in the first rear plate (6) of the injection mold (2). A cavity plate (8) is adjacent to the first rear plate (6) and defines an injection mold cavity (10). The gate (5) of the feed nozzle (4) opens into the cavity (10). The cavity plate (8) forms the outer surface (12) of the cavity (10) which in use defines the outer shape of the article to be injection moulded. A plurality of neck splits (14) are provided at the end (15) of the cavity (10) remote from the feed nozzle (4). The neck split (14) is shaped to mold the shape of one end of the article to be injection molded (in this embodiment, the neck finish of the par...

Abstract

An injection mold for injection molding an article having a base and a sidewall, the injection mold comprising: first and second mold parts which are adapted to be connected together in a closed configuration so as to define a mold cavity there between, the mold cavity having a base portion and a sidewall portion, an injector for injecting into the mold cavity molten material to be molded into the article, at least one portion of one of the first and second mold parts being movable when the first and second mold parts are in the closed configuration so as to vary the volume of the mold cavity, an actuator for selectively moving the at least one portion of one of the first and second mold parts in first and second directions so as to increase and reduce, respectively, the volume of the mold cavity.

Description

technical field [0001] The present invention relates to injection molds, injection molding apparatus, and methods of injection molding one or more articles. In particular, the invention relates to the injection molding of containers and parisons for containers from plastics material. Background technique [0002] Injection molding articles from plastic materials, in particular thermoplastic polymers, is known in the prior art. In particular, injection molding of containers and parisons for containers from plastics material is conventional in the prior art. [0003] It is often desirable to injection mold plastic containers with a small wall thickness, for example in order to reduce material costs. When it is necessary to injection mold containers with a high L / T ratio (where L is the flow length of the molten plastic material from the injection gate and T is the wall thickness), high injection pressure at the gate is required to guarantee the mold cavity Filled with molte...
