摘要： A process and apparatus for plastics injection moulding comprises injecting a quantity of molten plastics material into a mould cavity (30) and injecting pressurised gas (52) or pressurised liquid into the plastics material in the mould cavity. After holding the pressure of the gas or liquid on the plastics material in the mould cavity for a period of time in order to apply a packing pressure to the plastics material, a portion of the molten plastics material is expelled into one or more secondary cavities (32) or expelled back into the barrel (22) of the injection moulding machine. The step of injecting the plastics material may be effected with or without packing of the plastics material prior to the injection of the pressurised gas or liquid.

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 for producing a hollow molded article having a skin material comprises steps of: (a) providing a skin material between a first mold and a second mold which are in an open state; (b) supplying a molten thermoplastic resin between the first mold and the second mold; (c) closing the first mold and the second mold; (d) inserting a first hollow pin into the molten thermoplastic resin and supplying a gas into the resin through the first hollow pin to form a hollow part; (e) inserting a second hollow pin into said hollow part and supplying the gas through the first hollow pin while discharging the gas through the second hollow pin, thereby to circulate the gas in the hollow part to cool and solidify the molten thermoplastic resin; and (f) opening the first mold and the second mold and taking out the hollow molded article. A hollow molded article with a skin material can be efficiently cooled by means of a simple apparatus and operation without using a complicated apparatus or a special cooling material. Further, a hollow resin molded article having a skin material can be uniformly cooled in a short time without temporarily reducing the pressure in the hollow part and, therefore, a hollow molded article with a skin material free from distortion can be obtained.

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： The present invention relates to the fabrication of a moulded detail in a gas assisted moulding process, wherein molten polymer (23) is injected into the mould cavity (21) of a moulding tool, pressurized fluid (25) is supplied to the mould cavity through at least a first opening (22) to form a cavity (26) in the polymer and force the polymer towards the inner walls of the mould cavity, pressurized fluid (27) is thereafter supplied to the mould cavity through at least a second opening (24) localized remotely from said first opening to form a passage (28) through the polymer to said cavity, the polymer is cooled, pressurized fluid is removed and the mould cavity is opened to remove the moulded detail. The invention comprises that substantially equal amounts of pressurized fluid are supplied to the mould cavity through at least one of said openings (22, 24) and are simultaneously removed from the mould cavity through at least an other of said openings (24, 22), while the polymer being cooled, the pressure being held substantially constant in said mould cavity and the supplied amount having a lower temperature than the removed amount, such that heat (Q) is conveyed from the mould cavity via the arisen fluid flow and the cooling is speeded up.
