20090108498 | Drive for an Injection Unit and Method of Operating the Drive Unit - An injection molding machine conventionally includes a hydraulic circuit that communicates energy from a first motor. The hydraulic circuit typically includes pumps that regulate, in a conventional fashion, the flow of hydraulic fluid to control molding sub-assembles and functions, such as clamp up, stroke and injection. Additionally and conventionally, a dedicated electric drive is coupled to an extruder to effect rotation and operation thereof. According to the invention, the hydraulic circuit is extended to include a hydraulic motor drive whose operation is to rotate the extruder, thereby permitting the dedicated electric drive and its associated frequency and power control circuitry to be eliminated. By making use of previous idle periods when conventionally-driven hydraulic molding functions are effectively inoperative but when energy is nevertheless supplied to pumps by the first motor, the hydraulic drive is able to receive “free” energy from the first motor and to convert this into rotational energy to drive the extruder. In this way, the timing of operations in the molding machine is orchestrated such that the first motor can effectively provide contiguous or sequential support of multiple system functions, including extruder rotation, through a common but system-extensive hydraulic circuit. | 04-30-2009 |
