20140039808 | METHOD FOR ASSESSING WEAR IN MOLDING MACHINE - A first chromium mass concentration and a first reference mass concentration are extracted from a first test substance made by adding a predetermined amount of calcium to a predetermined amount of pellets; a reference value is calculated on the basis thereof. A second chromium mass concentration and a second reference mass concentration are extracted from a second test substance made by adding, to a predetermined amount of the substance contained in the molded part, an amount of calcium identical to the amount added to the pellets; a comparative value is calculated on the basis thereof. A screw can be determined to have wear whenever the comparative value is not less than a numerical value 60 times that of the reference value, whereas the screw can be determined not to have wear whenever the comparative value is less than a numerical value 60 times that of the reference value. | 02-06-2014 |
20130344187 | Electrically Driven Injection device for Die-Casting Machine - The invention is provided with a first injection electric motor used for low-speed injection and increasing pressure, a second injection electric motor used for high-speed injection, first and second power transmission mechanisms for transmitting rotary motion of the injection electric motors to a screw shaft, first and second clutch mechanisms provided in the power transmission mechanisms, an injection plunger advanced and withdrawn integrally with respect to a nut threaded on the screw shaft, and a controller for controlling the driving of the injection electric motors and the clutch mechanisms. The controller starts the second injection electric motor from a stopped state before the point in time where the high-speed injection step is to commence; and switches the second clutch mechanism from a disengaged state to an engaged state at the point in time where the high-speed injection step is to commence, or at a requisite timing prior thereto. | 12-26-2013 |
20130330436 | VERTICAL INJECTION MOLDING MACHINE - The vertical injection molding machine is provided with an electric servomotor which moves an injection drive unit up and down accompanying the rotation of a driven pulley via a ball screw mechanism, a timing belt by which the drive force of the electric servomotor is transmitted, and a driven pulley on which the timing belt is rotated, wherein an arc groove is formed on the driven pulley, and an election pin is provided which is inserted to the arc groove of the driven pulley when the timing belt is disconnected. When the election pin is inserted to the arc groove, the tip of the election pin applies pressure on an inclined portion by means of elastic force of a spring, slowing the rotational speed of the driven pulley and stopping the injection drive unit by an inner wall surface of the slowed driven pulley colliding with the ejection pin. | 12-12-2013 |
20130103184 | Molding Machine - A molding machine is provided for easily setting molding conditions. Molding navigation is stored in a microcomputer portion for performing drive control of the molding machine. When the molding navigation is activated, a plurality of setting screens required for setting molding conditions are displayed in a predetermined sequence on a display portion, and in each of the displayed setting screens, setting item display fields to which the molding conditions are to be input are displayed in a color different from the surrounding. An operator inputs predetermined setting values in the displayed sequence in the setting item display fields displayed in the color different from the surrounding. Thereby, the setting of the molding conditions can be completed. All molding conditions required for operating the molding machine can be set exhaustively, and the setting of the molding conditions can be performed highly efficiently and reliably, without special skills. | 04-25-2013 |
20110206797 | Molding Machine - Intended is to provide a molding machine using a built-in type motor as an injecting electric motor. In this molding machine, a mounting structure for such a transmission mechanism from a rotational motion to a linear motion, as changes the rotation of the built-in motor into the linear motion thereby to transmit the linear motion to an injecting member, is simplified to improve the assembling workability. For this improvement, a sleeve is fixed in the rotor of the built-in type motor. In the hollow portion of the sleeve, a screw shaft or the rotating portion of a ball screw mechanism and the sleeve are connected and fixed by a connecting member. A nut member or the straight portion of the ball screw mechanism is fixed on a member for performing straight motions together with the injecting member. | 08-25-2011 |
