The present invention relates to a lattice gate for directing streams of rubber into an injection molding device through a plurality of intersecting channels (78, 80) which thermally mix the streams of rubber within the gate (76) as they pass through the intersections of the flow channels permitting the injection time of the rubber into the mold cavity to be decreased while simultaneously reducing the time for curing the rubber within the mold.
La présente invention concerne une entrée en treillis pour diriger les flux de caoutchouc dans un dispositif de moulage par injection à travers une pluralité de canaux se croisant (78, 80) qui effectuent un mélange thermique des flux de caoutchouc dans l'entrée (76) lorsque ces derniers passent à travers les intersections des canaux d'écoulement, ce qui permet de réduire le temps d'injection du caoutchouc dans la cavité du moule, et de réduire simultanément le temps de vulcanisation du caoutchouc dans le moule.
