A clamping apparatus of an injection molding machine includes a servo motor installed at the center of the rear platen and two timing belts to drive two ball screws so as to push a five point inwardly bending toggle mechanism to open the mold, close the mold and mold clamping. Moreover, a servo motor is fixed to the lateral side of the movable platen to drive the nuts of the screw to rotate so as to push the ball screw, ejector rod and ejector plate to move linearly for achieving the object of ejecting. An electromotive motor on the rear platen will drive the mold adjusting means. By the assisting of the servo motor on the rear platen, the function and object of automatic mold adjusting can be achieved rapidly.

A hollow screw cooling device, which has a set of apertures provided on an oil-proof base on the driven end of the hollow screw. By having fixing screws go through the apertures and the through holes on the bearing press board and fixed on the bearing base, the oil-proof base can be fixed on the outer side of the bearing press board. By directly taking off fixing screws, the oil-proof base can be directly taken off the bearing base when maintaining or replacing the seal without disassembling the components such as the bearing and bearing device.

A tool holder of the hollow taper shank in a tool machine is disclosed. A resisting block supported by a spring is received within a tool holder. As the short knife is disposed within the tool holder, the elastic force of the spring can be overcome. At first, a plurality of steel balls and a resisting block are pushed inversely until the front edge of an wider portion of the short knife passes through the steel ball. Now, the spring will release the energy from elastic deformation so as to enforce the resisting block to move forwards and outwards so as to return to the original position. Thereby, the knife can be firmly secured.

A sliding unit includes a load-receiving device for permitting a load to be received thereon, a guiding device slidably mounting thereon the load-receiving device for permitting a direct relative sliding motion therebetween, and a load-sharing device mounted between the load-receiving device and the guiding device and capable of being in a rolling motion therebetween for resulting in a rolling contact effect therebetween. Such sliding unit can meet the demand of a high positioning precision/a high movement stability/a smaller friction coefficient/a better rigidity/a better vibration-resistivity.
