摘要： A molding tool for producing a component in a gas-assisted injection molding process includes a mold cavity, and an injection device with a pressurized gas source. The pressurized gas is fed into the plastic melt introduced into the mold cavity. The plastic melt is pressed against the inner walls of the mold cavity. The injection device has a piston with an injector head and moveably guided in a passage of a molding tool connected with the mold cavity. The injector head forms a part of the inner walls of the mold cavity in an idle position of the piston, and is pressed into the plastic melt as the piston moves to its operating position, so that the pressurized gas flows through the passage into the plastic melt in the mold cavity. The piston is moveable by the gas fed through the passage into the plastic melt.

摘要： A process and apparatus for injection molding and a plastic article having a hollow rib portion (72) is formed utilizing a spill cavity (73). The process includes the steps of sequentially injecting fluent plastic and gas into a mold cavity having a space defining at least one wall portion of the article and a channel (66) defining a rib portion (72) of the article. A quantity of fluent plastic is initially injected to substantially fill the mold cavity. A charge of pressurized gas is then injected into the channel (66) of the mold cavity to displace a portion of the still fluent plastic into the spill cavity (73) which is flow coupled to the channel (66). Preferably, the thickness of the rib portion (72) in cross section is at least twice as large as the thickness of the wall portion in cross section along the entire length of the rib portion (72). Also, preferably, the channel (66) is tapered along its length. The rib portion may be either internal or external to the article.

摘要： A method and apparatus of making a hollow-shaped body from molten resin including cutting a hole through the resin after it has cooled and into a fluid aperture formed during a fluid injection step which distributes resin over the interior mold surfaces. The fluid aperture is in communication with the interior of the hollow-shaped body and is preferably located in the runner or sprue of the mold. A cutting member (72) is located in the mold and has a surface (76) which at least partially defines a resin flow path. Cutting is accomplished by moving the cutting member (72) in a controlled fashion between a molding position and a relieving position to cut the hole. The cutting member (72) includes a fluid-relieving aperture (86). The fluid-relieving aperture (86) is in communication with the fluid aperture in the relieving position (84) of the cutting member (72) to relieve pressure through the fluid-relieving aperture (86).

摘要： A process for injection molding hollow plastic articles (46) includes the steps of sequentially injecting fluent plastic and gas into a mold cavity (36). A quantity of fluent plastic is initially injected to substantially fill the mold cavity (36). A charge of pressurized gas is then injected into the mold cavity (36) to displace a portion of the still-fluent plastic into a spill cavity (40) flow coupled to the mold cavity (36). The article (46) may be formed with an internal wall by introducing first and second gas charges into the mold cavity (36) at separate entry points. In one embodiment, the first and second charges are introduced substantially simultaneously. In a second embodiment, the charges are introduced sequentially. After the hollow plastic article (46) has solidified, the gas is vented.

摘要： A method and apparatus for producing an injection moulded plastics article comprises introducing a supply of plastics material (20) into a mould space (13), supplying a first stream of pressurised fluid into the molten plastics material to form a fluid containing cavity (25) therein, maintaining fluid pressure in the cavity until the plastics material can sustain the form dictated by the mould surface. During the step of maintaining fluid pressure in the cavity, at least a portion of the first stream of pressurised fluid is vented or allowed to vent from the cavity, and simultaneously a second stream of pressurised fluid from a second source (26; 40; 41) is supplied to the cavity, which second stream replaces that portion of the first stream which has vented from the cavity.

摘要： The invention relates to a plastic container (1), comprising a conduit (2), said conduit being connected to the wall of the plastic container (1) at least in sections and being configured as a single piece with said plastic container (1). The plastic container (1) is produced by means of injection moulding between a hollow mould and an inner mould placed inside said hollow mould. Said mould has a cavity (22) in which a stalk body is formed. Said stalk body is the starting material for the conduit (2). Material is blasted out of the stalk body before said stalk body fully hardens via the channels provided in the mould, using the gas internal pressure technique or the compression blasting technique, so as to produce the necessary conduit. The conduits can be arranged externally and/or internally and parallel to and/or at an angle with the container walls.

摘要： A method and system for injection molding plastic articles using pressurized fluid introduced into the article defining cavity or runner (20) of a mold (12) by a sealed pin or valve (18) having an orifice (16) and movable between open and closed positions. The method involves the initial step of injecting molten resin from the nozzle (14) of an injection molding machine through a resin injection aperture at an upstream position in a mold (12). The resin travels along a resin flow path in the mold (12) to the cavity (10) defining the shape of the molded article at a downstream position. During or after resin injection, a pressurized charge of fluid enters the flow path at the orifice (16) and passes into the mold cavity (10) to distribute molten plastic within the mold cavity (10). The fluid is contained within the mold cavity (10) under pressure until the article has set up, and it thereafter vented.
