TH3381B - Casting methods and tools for casting - Google Patents

Abstract

A casting with obtuse angles or circular arcs on the inner perimeter that is arranged in such a way that it is movable by the machine moving the filler, such as sand being filled in this casting. When heated, it decomposes. ready to produce combustion gas The metal pouring hole is connected to the melt and the hollow combustion suction device is arranged in such a way that it is in contact with the layer of fill object Combustion suction device with ventilation holes on the side wall. which forms a gas chamber, including a burner. At the top of it, the casting chamber is vibrated by a vibrating machine to densely compress the fill material and The molten metal is then poured from the molten metal drop holes into the mold to produce the product. And the resulting gas will be ignited and burned at the burner of the device. Suction for combustion by a igniter, arranged in such a way as to face the burner, absorbing gas. and then the casting chest will was moved to arrange the burner to have another igniter and also maintain suction

Claims (3)

1. The casting method, which consists of the process of filling non-combustible fill material in angular die casings. Obtuse or arc is a loop that surrounds the inside. The casting chest was arranged. To have characteristics that can be moved by a moving machine The filler is coated with a gas-permeable layer made of mineral particles and adhesives embedded in the filler.The filler decomposes while generating combustible gas when heated. Arrangement of pouring holes with holes for inserting molten metal into the mother Type in such a way that it touches the mold. Provide a hollow combustion suction device. Ventilated Air on the side wall which makes up the gas aggregation chamber Including burners In the upper part in such a way that it is in contact with the layer of the object fills as Said, and the aforementioned burner extends from the top surface of the layer of Fill object Vibration of the casting trunk by a vibration device. To contain dense fill objects Pouring molten metal from the furnace through a hole for dropping the molten metal Type such as to gas the molten metal by the metal. It melts and replaces the design with the product. The ignition and burning of the gas at the burner by the igniter, where the gas passes through the combustion chamber of the said combustion apparatus, through the aforementioned ventilation holes after passing through the gap in The filler to make the gas rise. A decrease in the pressure in the combined chamber by displacement Of the gas to assist in the suction through the ventilation holes and the movement of the said cylinder, and then arrange the burner There is another device after the movement of the casting trunk. Said had happened 2. Casting tools including A number of cast chests arranged in a movable manner by A mobile machine.Each casting chest has a section that is Obtuse corners or straight circular curves around the inside. A non-combustible filler is added to each of the said fillings, a vibratory machine for dense compression of the filler is buried in the filler to generate gas. Burns when heated A gas-through coating layer is created on the outside of such a design. The coating is made up of mineral particles and anchors. The pouring port has a hole for dropping the metal melted into the type. The pour hole is arranged in such a way that it touches the pattern. Suction device for hollow combustion Was arranged in a manner in contact with That layer of the object complements Suction devices for combustion There are ventilation holes on the side walls that make up the gas chamber. And the burner at the top part A number of igniters for igniting each burner and a furnace for supplying molten metal to a hole for dropping the melt into the mold. 3. The casting machine made according to claim 2, where the suction device For combustion, there is a protection on the outside of the machine, which operates in Machine axis (3 claims, 2 pages, 10 photos)
