A retention mechanism for an injection head (14) which includes a feed tube (24) capable of use with an injection bell (26) and an injection plate (28), wherein the bell and plate carry clamping apparatus actuable to secure the plate to the bell, includes an actuator (60,90) mounted on the feed tube (24) and a force transmitting apparatus also mounted on the feed tube (24). The force transmitting apparatus is removably engageable with the clamping apparatus so that the force transmitting apparatus is movable by the actuator (60,90) to actuate the clamping apparatus. An injection bell (26) and/or an injection plate (28) can be rapidly removed and replaced with a different injection bell and/or injection plate without the need for lengthy adjustments. <IMAGE> |
