A mold for foam molding which can sufficiently prevent burrs from being formed on a molded product, and a foam molding method using the mold are provided. A groove 6 into which a packing seal is to be fitted is formed in a mating surface 3a of a lower mold 3 so as to extend around a cavity 7. The groove 6 has a deep groove portion 6a which is deeply recessed from the mating surface 3a, and a shallow groove portion 6b which is located on the cavity 7 side with respect to the deep groove portion 6a and which continues to the deep groove portion 6a. A portion of the mating surface 3a that extends from its edge on the cavity 7 side down to the groove 6 has a width "a" of from 0.1 mm to 10 mm. A packing seal 5 has a base portion 5a which is inserted into the deep groove portion 6a, and an overhang portion 5b which continues to the base portion 5a and is engaged with the shallow groove portion 6b.

Method and apparatus are provided for sealing interfaces within an injection molding machine having a first surface and a second surface includes an active material actuator configured to be disposed in a manner suitable for generating a force between the first surface and the second surface. The active material actuator is configured to generate a force in response to sense signals from a controller optionally connected to active material sensors. Methods and apparatus are also provided for centering a nozzle tip within a gate opening, and adjusting tip height of a nozzle tip with respect to a gate opening, also using active material inserts.

It is enabled to produce in short time a molded product having a shape resembling that of a three-dimensional, deep-bottomed, concave container having a thin side wall, even by use of a molding material of poor moldability, such as an environmental low-load-type material. Before completion of a mold closing step of a mold apparatus, charging the molding material into a cavity of the mold apparatus is started; before completion of the mold closing step, charging the molding material in a predetermined amount is completed; and after completion of the mold closing step, a mold clamping step of the mold apparatus is performed so as to produce a molded product of the environmental low-load-type material
摘要:
An injection molding apparatus for producing a plastic product having a grain pattern thereon. The apparatus includes a female die having a grain pattern on an inner surface thereof, the female die further provided with a vacuum drawing mechanism for drawing a vacuum therethrough, and a male die having an injection aperture for injecting a thermal formable plastic material therethrough. The male die further includes a burr cutter adapted to slide fit in a gap between the male die and the female die and a guide pin with a spacer provided at four comers of the male die for controlling a distance between the male die and a female die.
摘要:
Die Erfindung betrifft ein Verfahren zum Spritzgießen eines Kunststoff-Formteils in einem Spritzgießwerkzeug, das die Schritte aufweist: a) Einspritzen einer vorgegebenen Menge Kunststoffschmelze in das Spritzgießwerkzeug; b) Einbringen von Druckfluid, insbesondere Druckgas, zwischen einen Teil der Wandung des Spritzgießwerkzeugs und der eingespritzten Kunststoffschmelze; c) Abkühlenlassen der Kunststoffschmelze, bis das Kunststoff-Formteil selbsttragend ist; d) Entformen des Kunststoff-Formteils. Erfindungsgemäß ist vorgesehen, daß während oder nach dem Schritt a) und während oder vor dem Schritt b) die Kavität (3) des Spritzgießwerkzeugs (2), vorzugsweise durch aktivieren von mindestens einer Dichtung (4), gegenüber der Umgebung abgedichtet wird. Des weiteren betrifft die Erfindung eine Spritzgießform (2), insbesondere zur Durchführung des Verfahrens nach mindestens einem der Ansprüche 1 bis 6, zum Spritzgießen eines Kunststoff-Formteils, die aufweist: ein aus mindestens zwei Hälften bestehendes Formwerkzeug (2) mit einer Kavität (3); mindestens ein Fluideinspritzelement (7), das Druckfluid, insbesondere Druckgas, von einer Wandung der Kavität (3) aus in die Kavität einleitet, so daß sich ein Fluidpolster zwischen Wandung und der ins Formwerkzeug eingebrachten Schmelze bildet. Erfindungsgemäß ist hier vorgesehen, daß mindestens eine der zwei Hälften des Formwerkzeuges mit einer Dichtung (4) ausgeführt ist, um die Kavität (3) des Spritzgießwerkzeugs (2) gegenüber der Umgebung abzudichten.
