ABSTRACT:
An arrangement of oil cylinders of a plastic injecting machine is provided which positions a large oil cylinder and a small oil cylinder respectively on both the left and right sides of an oil cylinder base and a bearing base. The large and small oil cylinders are located at such a distance away from a material injecting cylinder that the oil seals of the four oil cylinders are not heated by the electric heaters that heat the material injecting cylinder. By this arrangement, the oil seals have a normal service life. In addition, an oil route plate is located on the bearing base to secure oil pipes formed of hard steel connected between the four oil cylinders and an oil pump, to keep oil flowing smoothly.
