A casting apparatus includes: a mold including a first mold segment and a second mold segment; and a transfer device that is configured to transfer a core to the first mold segment and place the core in the first mold segment, and to receive and transfer a casting. The transfer device includes a support part, a robot arm, a core grasping mechanism being provided on the support part, and a casting receiving part being provided on the support part. The transfer device is configured such that the robot arm moves the core grasping mechanism so as to place the core in the first mold segment, and moves the casting receiving part so as to receive the casting by the casting receiving part.

An assembly system includes a molding machine that molds first parts and second parts and a robot having an assembly unit including a first holder that holds the first parts and a second holder that holds the second parts with each other. The first parts and the second parts that are molded by the molding machine are removed from the mold while being held by the first holder and the second holder of the robot. At least one of the first holder and the second holder is moved relative to the other so as to assemble the first parts and the second parts without releasing the first parts held by the first holder and the second parts held by the second holder.

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.

A robot arm for die casting according to an embodiment of the present invention, which clamps and moves a cast-iron product, includes: an arm unit having a plurality of joints; a hand unit coupled to an end of the arm unit to clamping the cast-iron product; and a cooling unit having a plurality of nozzles disposed at the hand unit and separately operating to spray cooling water to a surface of the cast-iron product.

A diecasting mold, comprising a first mold plate which is hot in operation and comprising at least one diecasting nozzle with an outlet point for a melt, and a second mold plate which forms a cold side. A mold cavity is formed between the first and second mold plates in a closed state of the diecasting mold, in which mold cavity a molded part can be produced from solidified melt introduced into the mold cavity via at least one melt channel, at least one diecasting nozzle and the at least one gate. The diecasting mold further comprises a demolding system, the demolding system comprising an ejector assembly, a drive device, and a force transmission device. A hot chamber system for diecasting metal melt according to the hot chamber method is also taught, a method for diecasting metal, and a use of a diecasting mold.

Nuclear waste, such as, but not limited to, spent nuclear fuel (SNF) assemblies or portions thereof, are chipped and compacted into (waste) pucks that are placed within diecast molds, and then diecast injection molding occurs within the diecast molds and around the pucks that are emplaced within those diecast molds, with injected molten alloy(s), to form solid metal ingots upon sufficient cooling after the diecasting injection that contain within the ingots the emplaced pucks. The molten alloy(s) may contain a copper alloy. The molten alloy(s) may also contain neutron absorbers. The ingots may be placed into waste capsules. The ingots and/or the waste capsules may be landed in deeply located horizontal wellbores. The deeply located horizontal wellbores may be at least partially located within deeply located geologic formations.

A casting apparatus includes: a mold including a first mold segment and a second mold segment; and a transfer device that is configured to transfer a core to the first mold segment and place the core in the first mold segment, and to receive and transfer a casting. The transfer device includes a support part, a robot arm, a core grasping mechanism being provided on the support part, and a casting receiving part being provided on the support part. The transfer device is configured such that the robot arm moves the core grasping mechanism so as to place the core in the first mold segment, and moves the casting receiving part so as to receive the casting by the casting receiving part.

An assembly system includes a molding machine that molds first parts and second parts and a robot having an assembly unit including a first holder that holds the first parts and a second holder that holds the second parts with each other. The first parts and the second parts that are molded by the molding machine are removed from the mold while being held by the first holder and the second holder of the robot. At least one of the first holder and the second holder is moved relative to the other so as to assemble the first parts and the second parts without releasing the first parts held by the first holder and the second parts held by the second holder.
