| 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 |
| 20110180166 | HYDRAULIC CIRCUIT OF INJECTION CYLINDER IN DIE-CASTING APPARATUS - A hydraulic circuit of an injection cylinder in a die-casting apparatus, which can achieve IN restriction and OUT restriction in a quickly switchable manner with a single circuit and which allows manufacturing of a high-quality molded product. The hydraulic circuit includes: a first pressure oil path supplying pressure oil to the injection cylinder; a second pressure oil path returning the pressure oil from the injection cylinder; a first flow control valve controlling a flow of the pressure oil through the first pressure oil path; a second flow control valve controlling a flow of the pressure oil through the second pressure oil path; a bypass pressure oil path connected to the second pressure oil path for bypassing the second flow control valve; a bypass on-off valve provided on the bypass pressure oil path and opening/closing the bypass pressure oil path with the pressure oil; and a controller controlling each valve. | 07-28-2011 |
| 20110159133 | Injection Molding Machine - Provided is an injection molding machine using a built-in type motor as a measuring electric servomotor. In order to reduce the entire length of the machine (the injection molding machine), the metering electric motor is exemplified by a hollow built-in type motor, which includes a cylindrical stator, and a cylindrical rotor positioned in the stator. A sleeve is fixed in the rotor of the built-in type motor, and a member fixing the rear end portion of a screw and the sleeve are connected/fixed. Moreover, a nut member as a straight portion of a ball screw mechanism for converting the rotation of an injecting electric motor into linear motions and the sleeve are connected/fixed. | 06-30-2011 |
| 20110094702 | Die Casting Machine - Provided is an electric die casting machine capable of achieving high injection speed and high boost pressure. An injection unit ( | 04-28-2011 |
| 20110020485 | Molding Machine - The invention is to provide a molding machine which has a drive system miniaturized and having high responsibility to start control, suspension control, acceleration control and deceleration control so that products can be molded with higher efficiency. A molding machine of a direct drive system for transmitting rotary power of an electric motor | 01-27-2011 |
| 20110018156 | In-Line Screw Type Injection Molding Machine and Method of Controlling the Same - The invention is to provide an in-line screw type injection molding machine which can have a simplified configuration of an injection mechanism and a metering mechanism. The in-line screw type injection molding machine is characterized by comprising: a metering motor | 01-27-2011 |
| 20100263461 | DIE-CAST ARTICLE QUALITY JUDGING METHOD, DIE-CASTING MACHINE SELECTING METHOD, AND DIE-CASTING CONDITION DETERMINING METHOD - The present invention provides: a die-cast quality judging method that can easily judge whether or not a prescribed quality is satisfied; a die-casting machine selecting method of judging whether or not plural prescribed qualities are satisfied; and a die-casting condition determining method of determining die-casting conditions. | 10-21-2010 |
| 20090169671 | INJECTION MOLDING MACHINE - Problem to be Solved An injection molding machine is provided which prevents, when molding a molding product, a molded part not to be used as a product to be integrally molded together with a molding product to be a product from being uselessly produced and improves production efficiency. | 07-02-2009 |
| 20090017152 | METHOD FOR CONTROLLING MEASUREMENT IN INJECTION MOLDING MACHINE, AND INJECTION MOLDING MACHINE - A method for controlling measurement in a motor-driven in-line screw type injection molding machine using servo-motors as a measurement driving source and an injection driving source. Control is made so that all of a measured value of back pressure controlled by the measurement servo-motor, a measured value of an astern speed of a screw controlled by the injection servo-motor, and a measured rotational speed of the screw turn zero concurrently at timing when the screw reaches a measurement completion position. Thus, suck-back can be made dispensable. | 01-15-2009 |
