Thermoregulated rubber distributor for injection molds

A thermoregulated rubber distributor (5) for injection molds, the distributor comprising:

• two or more modular units (10, 11), a plurality of sleeves (14) each interchangeably insertable in the two or more modular units (10, 11), one or more injectors (13) to feed melted rubber to the distributor (5) and one or more discharge nozzles (7) to discharge the melted rubber from the distributor (5) towards an external mold,
• wherein each of the plurality of sleeves (14) has a through hole (16) extending along a longitudinal axis of said each of the plurality of sleeves (14) and a groove (15′) extending on a side surface of each of the plurality of sleeves so that the groove (15′) and an inner surface of the two or more modular units (10, 11) define a coil (15) intended to be supplied with a thermoregulating fluid whenever each of the plurality of sleeves (14) is inserted into two or more modular units (10, 11),
• wherein the two or more modular units (10, 11) can be constrained to one another to define one or more channels (16′, 16″) for distribution of the melted rubber that extend from an injector (13) to one or more discharge nozzles (7), depending on a desired path, and
• wherein the through hole (16) of each of the plurality of sleeves (14) defines corresponding lengths of at least one of the one or more channels (16′, 16″) for distribution of the melted rubber;
• and
• wherein at least one sleeve (14) has a frontal through hole (15″) through which the relative coil (15) is set in fluid communication with another coil (15) of an adjacent sleeve (14) or with a corresponding duct provided in the related modular unit (10, 11).
