AN INJECTION MOLDING MACHINE

摘要

PURPOSE: An injection molding machine is provided to help a transferring plate to be promptly released from a tie bar during injection molding process since a high-pressure cylinder is installed in a transferring plate and first and second lock cylinders are installed, thereby facilitating high-speed injection work. CONSTITUTION: An injection molding machine including a double lock cylinder comprises a fixing plate, a transferring plate (280), a tie bar (490), a first lock nut (340), a second lock nut, a first lock cylinder (330), a second lock cylinder (400) and a high-pressure cylinder (130). The high-pressure cylinder is installed in the transferring plate and pressurizes the first and second nut locks. The transferring plate is fixed to the tie bar by the first and second lock cylinders and at the same time, the high-pressure cylinder exerts a front force on the transferring plate with oil pressure.
