The present invention generally relates to an injection molding apparatus, comprising a manifold including a plurality of manifold channels and a plurality of nozzles. Each of the nozzles defines a nozzle channel in fluid communication with one of the manifold channels and including a plurality of nozzle bodies coupled in tandem by a removable and secure connection. The nozzle bodies include at least a upstream nozzle body and a downstream nozzle body. The upstream nozzle body has an upstream end adjacent said manifold channel, and the downstream nozzle body has a downstream end adjacent a mold plate. A removable nozzle tip is retained in a downstream end of each downstream nozzle body. The nozzles also include a plurality of heaters, wherein at least one heater is embedded into each nozzle body.
La présente invention se rapporte en général à un moule à injection qui comprend un distributeur constitué de multiples canaux de distribution et de multiples buses d'injection. Chaque buse comporte un canal en communication fluide avec un des canaux du distributeur, et comprend de multiples corps de buses jumelées au moyen d'un raccordement amovible et sûr. Les corps de buses comprennent au moins un corps de buse amont et un corps de buse aval. Le corps de buse amont comporte une extrémité amont contiguë audit canal de distributeur, et le corps de buse aval comporte une extrémité aval contiguë à une plaque de moule. Un embout de buse amovible est retenu dans une extrémité aval de chacun des corps de buses aval. Les buses comprennent aussi de multiples éléments de chauffage où au moins un élément de chauffage est noyé dans chaque corps de buse.
