A three-plate die casting mold for producing a metal die-cast part by die casting a molten metal includes a first, second, and third mold part, where the third mold part is disposed between the first and second mold parts. Molten metal is feedable to a die cavity through a sprue system where the sprue system has a plurality of feed channels that are disposed in the third mold part and open into the die cavity. The plurality of feed channels have a respective tapering at a die cavity-side end where the respective tapering locally decreases a channel cross section such that a predetermined breaking point is generated during a die casting operation which allows a defined separation of the metal die-cast part from a sprue created in the sprue system when the three-plate die casting mold is being opened.

A smart trim die assembly for providing multiple internal operations during a stroke. The smart trim die assembly (10) comprises a first die (12), a second die (14), and a cavity (20) formed between the first die and second die. A plurality of sensors (22) are located between the first die and the second die for measuring the distance therebetween during a stroke. A series of tools are integrated into one of the first die or second die and each perform one of trimming, piercing, dimpling, and tapping operations. The smart trim die assembly further includes a processor (210) and a memory device (214) for receiving readings from the sensors. The memory device further contains instructions that, when executed by the processor, cause the processor to, in response to the sensor reading a predetermined distance, instruct the series of tools to perform one or more of the operations.

A serial multi-cavity high pressure casting apparatus includes a three stage mold comprising a fixed mold, an operation mold, and a medium mold disposed between the fixed mold and the operation mold, a main sleeve penetrating a lower portion of the fixed mold, and having molten metal injected thereinto, a main runner formed to extend upward from the main sleeve, an auxiliary sleeve branched to both directions from the main runner, an auxiliary runner formed to extend upward from each of both ends of the auxiliary sleeve and connected to each of a first cavity formed between the fixed mold and the medium mold, and a second cavity formed between the medium mold and the operation mold, and a sleeve core disposed on a lower portion of the medium mold, and having the main sleeve, the main runner, and the auxiliary sleeve inserted thereinto.

A backflow prevention device of a light metal injection device and a backflow prevention method thereof of the disclosure include: a valve which has a valve body made of a corrosion-resistant and heat-resistant steel and a valve seat made of a ceramic, and in which the valve body advances and is seated on the valve seat to close a communication path communicating a melting unit and an injection unit, and the valve body retracts and is separated from the valve seat to open the communication path; a valve body drive device which moves a drive body to which the valve body is connected forward and backward; a position sensor which detects that the drive body has reached at least a predetermined advance limit position; and a valve body drive control device which controls the valve body drive device based on a signal of the position sensor.

A system for separating a part from a monolithic tree includes a camera positioned facing the tree and configured to identify a cut mark on a gate of the tree, the tree including a runner, the part connected to the runner with the gate, each of the runner, the gate, and the part including a cast material; and a robotic arm configured to manipulate at least one of an orientation and a position of the tree.

A three-plate pressure die casting mold for producing at least one metallic die casting part by die casting a metal melt, includes first, second and third mold parts and at least one mold cavity as well as a sprue system. In the third mold part there is at least one spring-loaded pressure element which, when opening the die casting mold, presses the sprue produced in the sprue system against the first mold part, whereby the sprue is retained and tears off from the die casting part in a defined manner. A method for pressure die casting using the three-plate pressure die casting mold is disclosed.

A three-plate pressure die casting mold for producing at least one metallic die casting part by die casting a metal melt, includes first, second and third mold parts and at least one mold cavity as well as a sprue system. A relatively movable pressure plate is arranged in the third mold part, which, when opening the die casting mold, presses the sprue produced in the sprue system against the first mold part, whereby the sprue is retained and tears off from the die casting part in a defined manner. A method for pressure die casting using the three-plate pressure die casting mold is disclosed.

A trimming-deburring assembly includes an upper fixed plate, a lower fixed plate, an intermediate mobile plate, movable between the upper and lower fixed plates, in a vertical direction, and command and movement means for moving the intermediate mobile plate, having an electric motor and a movement group operatively connected on a top to the electric motor and on the bottom to the intermediate mobile plate. The movement group has a spindle member drivable in rotation by the electric motor, having a spindle cavity and a worm gear element provided with a worm gear cavity defined by a threaded worm gear wall, and a worm screw element at least partially housed in the spindle cavity and in the worm gear cavity, having a threaded screw wall engaged with the threaded worm gear wall to receive rotary action of the worm gear element, and a lower end operatively connected to the lower fixed plate.

A method and an automatic degate system includes a fixture configured to receive a workpiece, a registration device configured to position the workpiece in a predetermined orientation and position, and a robotic arm. The robotic arm is configured to move in at least a gripping direction. The robotic arm includes a gripping device configured to engage the workpiece at predetermined locations after being moved in the gripping direction. The robotic arm also includes a support bracket, a plurality of elongate rods each having a predetermined length and extending orthogonally from the support bracket, and a respective cutting puck coupled to a distal end of each of the plurality of elongate rods. The cutting pucks configured to remove a biscuit of excess material from the workpiece while being moved in the gripping direction.
