An injecting machine for two different liquid material includes an injection cylinder having a nozzle disposed on a distal end thereof. A plunger is reciprocally received in the injection cylinder for undergoing reciprocating movement between an advanced position and a retracted position, with the plunger injecting a liquid mixture of the two different liquid materials as the plunger moves to the advanced position. A moving mechanism causes the plunger to reciprocate between the advanced position and the retracted position. A mixing mechanism is disposed on the injection cylinder for mixing the two different liquid materials together to feed the liquid mixture into the injection cylinder. A support plate supports a proximal portion of the injection cylinder. The mixing mechanism is supported in its entirety by the injection cylinder.
