Abstract

La présente invention concerne un appareil d'isolation thermique et de régulation de la température d'un cylindre d'une machine d'injection. L'appareil selon la présente invention permet d'isoler thermiquement le cylindre par un corps d'isolation thermique et améliore donc non seulement l'efficacité de chauffage du cylindre, mais empêche également la dissipation de chaleur vers l'extérieur, comme par exemple vers un espace intérieur, ce qui permet de fournir un environnement de travail confortable. En outre, l'appareil selon la présente invention refroidit chaque pièce du cylindre si nécessaire au moyen d'air au lieu d'un réfrigérant, comme par exemple un liquide de refroidissement, une huile de réfrigération ou de l'azote gazeux, ce qui permet de régler la température du cylindre de manière efficace.
