Method and apparatus for the intermittent manufacture of multi-layer shaped thermoplastic parts with a foamed core and an unfoamed shell, where at first a part of the unfoamed plastic and later a plastic that contains a foaming agent is injected simultaneously with additional unfoamed plastic into a

대표청구항 ▼

Apparatus for the fabrication of a plastic article in a closed mold, the article having a foamed core and an unfoamed outer shell, comprising: a. an injection head having a shaped outer surface adapted to lie firmly against the injection entrance of the mold, the head having a flow passage leading to an exit passage having the general shape of a surface of revolution, the head also having a bore coaxial of but non-coextensive with the exit passage, b. a sleeve slidably carried in the said bore and having a nose shaped to fit snugly in the said exit passage on occasion, the sleeve having a central longitudinally-extending flow passage leading to a central nozzle in the said nose, the sleeve also having a cylindrical bore coaxial of but non-coextensive with the central nozzle, c. a needle slidably carried in the said bore in the sleeve and having a nose shaped to fit snugly in the said central nozzle in the nose of the sleeve, and in operative relationship to said injection head, d. means for presenting plastic with no blowing agent through the flow passage of the sleeve and plastic with blowing agent through the flow passage in the head, means to actuate the apparatus to a first condition in which the needle lies axially away from the central nozzle and the sleeve lies with its nose in contact with the exit passage of the head, so that only plastic with no blowing agent flows into the mold; means for then activating the apparatus to a second condition in which the sleeve lies axially away from the exit passage of the head while the needle remains away from the central nozzle, so that both plastic with blowing agent and without blowing agent flows into the mold; means for subsequently activating the apparatus to a third condition in which the needle lies in the central nozzle while the nose remains out of contact with the exit passage, so that only plastic with blowing agent flows into the mold; and means to then activate the apparatus to a fourth condition in which the needle lies out of the central nozzle and the nose of the sleeve lies in contact with the exit passage, so that only plastic without blowing agent flows into the mold to provide the molded part with an unfoamed skin in the area of its surface adjacent the injection entrance of the mold.
