Abstract
L'invention concerne un procédé de moulage par injection et de refroidissement de pièces en matière plastique (en particulier plastique mousse) ainsi qu'un dispositif pour l'application du procédé. Aussitôt après l'introduction de la matière plastique dans la cavité du moule à injection composite 1, 2, on fait arriver entre cette matière et cette cavité un gaz réfrigérant, liquéfié, de telle manière que, pendant une durée de circulation réglable, le réfrigérant s'échappe à l'état gazeux par un ou plusieurs orifices réglables 16, la pièce moulée, pourvue, par le réglage de la durée de la circulation du réfrigérant, d'une enveloppe superficielle refroidie étant alors éjectee et amenée aussitôt après dans un bain réfrigérant pour achever de s'y refroidir. Le procédé permet de travailler à une cadence extrêmement rapide.
