20250079956 · 2025-03-06 ·

A die cast part, such as an electric drive unit, a high pressure die casting system, and a method of forming a die cast part. The high pressure die casting system includes a shot sleeve including a pour hole, a launder connected to the pour hole, a furnace connected to the launder, a mold cavity connected to the shot sleeve by a sprue post, and a heating system including at least one proximal channel located under the pour hole under the shot sleeve. The feedstock is melted in the furnace and transferred by a launder into the preheated shot sleeve through a pour hole. The feedstock is injected into a mold cavity, wherein the temperature of the feedstock is above the solidus temperature of the feedstock upon entering the mold cavity.

HIGH-PRESSURE CASTING METHOD AND HIGH-PRESSURE CASTING DEVICE
20170036268 · 2017-02-09 · ·

Provided is a high-pressure casting method and a high-pressure casting device which are capable of safe and high-quality casting of a high-fusion-point metal having a fusion point exceeding 1000 K. After melting a casting material (1) inside a melting container (2) of cartridge type, the melting container (2) is linearly moved to pass through a guide (14) attached to a casting port bush (13) to thereby be communicated with the casting port bush (13). The melting container (2) is brought into close contact with the guide (14) and is setting to a cooling state. After the elapse of prescribed time, a plunger (50) is brought into contact with a plunger tip (4), and is immediately transferred together with a molten metal to the casting port bush (13). The molten metal is pressurized inside the casting port bush (13), and is injection-filled into a cavity (10).

Casting machine

A casting machine having a furnace body, a first heater, a first surface and pressure means. The furnace body has a melting portion and a holding portion, material being supplied and melted to form the molten metal in the melting portion, the holding portion holding the molten metal which has flowed out from the melting portion. The first heater heats the material supplied to the melting portion to melt it. The first surface is provided on a hearth surface of the melting portion and has concavities and convexities, the material to be heated being laid on the first surface.

CAST MOLDING METHOD AND DEVICES THEREOF

A cast molding method accomplishes the cast molding by a smelting chamber, a casting chamber, a hinge press system and a vacuum system. First, a metallic die is assembled in the casting chamber and then a metallic material is put in the smelting chamber. Next, the metallic material is heated up in a vacuum state and the casting chamber is pre-heated at a same time. After the metallic material in the smelting chamber has been melted down and the casting chamber has been vacuumized, the melted metallic material is filled into the metallic die, and then the hinge press system is turned on to cast mold the metallic die, resulting in a semi-solid product. After the semi-solid product has been cooled down, the product of cast molding is accomplished according to the present invention.
