MULTI-DIRECTIONAL UNIBODY CASTING MACHINE FOR A VEHICLE FRAME AND ASSOCIATED METHODS
A multi-directional casting machine for casting a frame of a vehicle is described herein. The casting machine may include a central hub having a cover die portion and a plurality of ejector die portions translatable relative to the cover die portion and configured to meet at the central hub. The plurality of ejector die portions include first and second ejector die portions configured to translate along a first axis and a third ejector die portion configured to translate along a second axis extending substantially perpendicular to the first axis between closed and open positions. The first, second, and third ejector die portions are adjacent a first, second, and third sides, respectively, of the cover die portion in the closed positions and spaced apart from the cover die portion in the open positions. The plurality of ejector die portions form a mold cavity corresponding to a portion of a vehicle frame.
Thermal camera system for die-cast machine
A die cast machine for producing a manufactured part includes a fixed die maintaining a fixed position in the die cast machine. The fixed die has an internal fixed die surface. A movable die moves from a first position to a second position in the die cast machine. The movable die has an internal movable die surface. A sprayer applies a die release agent to the internal fixed die surface and the internal movable die surface before operation of the die cast machine. A first thermal imaging apparatus takes thermal images of the fixed die, and a second thermal imaging apparatus takes thermal images of the movable die. Application of die release agent is controlled by the temperatures of the fixed and movable dies as determined by the thermal images.
Injection molding feedstock delivery system
A feedstock delivery system for injection molding includes a vessel unit that includes a vessel with an internal volume and an inlet for receipt of a feedstock. First and second dispensing units are alternatively connectable to the vessel unit and each include first and second ends, first and second valves, and a buffer chamber. The first end is connectable to the dispensing unit such that the buffer chamber is in communication with the internal volume of the vessel. The second end is connectable to an injection mold and defines an outlet of the feedstock delivery system. The outlet is in communication with the buffer chamber, and the buffer chamber is positioned between the first and second valves. The buffer chamber of the first dispensing unit defines a first chamber volume, and the buffer chamber of the second dispensing unit defines a second chamber volume greater than the first chamber volume.
Full-servo multi-axis die-casting machine
A full-servo multi-axis die-casting machine includes an injection device body, a gooseneck operation device body and a plurality of mold locking device bodies. The injection device body includes a hollow first frame, a first servomotor, a screw, a transmission unit and an injection unit, so that the screw is caused to rotate by the first servomotor and is converted by the transmission unit into vertical reciprocal movement. The gooseneck operation device body includes a second servomotor, a first transmission arm and a second transmission arm, so that the first transmission arm and the second transmission arm are driven by the second servomotor to allow bifurcation sections to oscillate with rotation of the transmission section. The mold locking device bodies each include a third servomotor, a third transmission arm and a mold retention slide block, so that the mold retention slide block is reciprocally movable in the channel.
Full-servo multi-axis injection device for die-casting machine
A full-servo multi-axis injection device for a die-casting machine, including a main body, including a hollow frame, servo motor, screw rod, transmission unit, and injection unit, the servo motor being configured on a top of the frame, one end of the servo motor having a deceleration mechanism in connection with one end of the screw rod, another end of the screw rod being in connection with the transmission unit, another end of the transmission unit the injection unit, and the injection unit having at least one input and at least one output. Whereby, the servo motor drives the screw rod to rotate upon running, and the transmission unit converts the rotation of the screw rod to a vertical reciprocating movement.
Gooseneck operation device of full-servo multi-axis die-casting machine
A gooseneck operation device of a full-servo multi-axis die-casting machine includes a gooseneck operation device body, which includes a servomotor, a first transmission arm, a second transmission arm, and an injection unit. The servomotor includes a speed reduction mechanism, which is mounted, in an eccentric manner, in a spindle hole formed in the first transmission arm. The second transmission arm includes a rotatable joint section rotatably mounted to an opposite end of the first transmission arm and a transmission section that is provided with two bifurcation sections. The injection unit includes projection sections coupled to the bifurcation sections such that the operation of the servomotor causes the first and second transmission arms to drive the transmission section to rotate and make the bifurcation sections to oscillate frontwards and rearwards with the rotation of the transmission section so as to drive the injection unit to operate.
Apparatus for creating at least one metal component and method therefor
Method and apparatus for creating at least one metal component by injecting flowable metal casting material into at least one cavity of a multi-part casting mold. Arranged successively downstream, apparatus includes a conveyor device for the flowable metal material, a distributor unit and the mold. The distributor unit includes an inlet channel connected to the conveyor device, and multiple outlet channels each having an outlet nozzle, such that casting material fed under pressure via the distributor inlet channel is injectable via the outlet nozzles into the at least one cavity of the mold to simultaneously fill the at least one cavity with casting material via the outlet nozzles. To produce the component with high process reliability in high quality, at least one of the outlet channels is connected to the mold in a sliding manner to enable relative movement between the outlet nozzle of the outlet channel and the mold.
Ultrasound assisted shot chamber for die casting applications
A method and apparatus for producing semi-solid material castings from its liquid state in a shot chamber of a die casting machine where the liquid material is poured into a shot chamber and rapidly cooled from its liquid state to temperatures below its liquidus. High-intensity ultrasonic vibration is coupled to the plunger, shot plate, or sprue-spreader while the cast material is injected by the plunger to fill the die cavity. The combined action of rapid cooling from the shot chamber, vigorous pushing by the plunger, and radiation of ultrasonic vibration on the cast material in the shot chamber directly turns the initial liquid material directly into a semi-solid slurry by breaking up dendrites and making these dendritic fragments globular. The slurry is then injected into the die cavity to form a casting.
