TESTA DI MESCOLAMENTO CON CORPO DI ACCUMULO

摘要

A mixing head for mutually reactive components, e.g. of a synthetic resin to be injected into a mold cavity, comprisess a control member which is shiftable in a mixing chamber opening into the mold cavity between a position in which mixing of the components can occur in this chamber and a position in which the member expels the mixture from the chamber and provides recirculating passages for the two components. A displacement body can be inserted into the chamber to control the mixing action by a fluid-operated actuator hydraulically coupled to a fluid displacement member shifted by the control member.
