摘要： The invention relates to the field of aluminum wheel casting molds, and more particularly relates to a closed-loop control method and system for a mold temperature in a wheel casting process. The control method includes: step 1, acquiring data, that is, acquiring a plurality of mold position temperatures, and cooling pipeline opening and closing signals in a target wheel casting process according to a fixed frequency; step 2, storing, based on acquired mold opening and closing signals of casting equipment, the acquired data in a database in the form of a unique ID according to a single wheel casting process; step 3, calculating new process parameters based on the acquired plurality of position temperatures and time; and step 4, integrating the calculated process parameters, and issuing the process parameters to a PLC of a casting equipment to perform new casting. According to the invention, the temperature control parameters are calculated based on the acquired temperature data and time process to form the temperature control process of the casting process, which solves the technical problem of significant fluctuations in the quality of the low-pressure casting process of aluminum wheels and improves casting stability and yield.

摘要： An apparatus for manufacturing items of light alloy or similar comprises a mould (10) that includes two half-moulds (12, 14), lower and upper, able to be coupled together. The lower half-mould (12) defines a moulding cavity (20) adjacent to a supply duct (16) of liquid metal that passes through it up to an introduction passage (18) of the liquid metal in the moulding cavity (20). The upper half-mould (14) is associated with at least one moveable punch (24) provided with a moulding surface (21) that defines the shape of an item to be moulded together with the moulding cavity (20). Each punch (24) performs the function of a shutter to stop the flow of liquid metal towards the moulding cavity (20). The apparatus includes temperature control means and temperature sensors connected with a control unit (32) that prevents the movement of the moveable punches (24) if the temperature of both half-moulds (12, 14) is not comprised within a predetermined range of values.

摘要： Molten metal M is raised to the vicinity of a gate 11 of a cavity 9C by increasing the pressure in a holding furnace 5 with gas, and thereafter the cavity 9C is filled with the molten metal M by decreasing the pressure in the cavity 9C by suction and further increasing the pressure in the holding furnace 5. Thereafter, the decompression of the cavity 9C is stopped after a preset filling time, and the compression of the holding furnace 5 is stopped when solidification of the molten metal M is completed. In this way, the suction is minimized, and it becomes possible to employ a simple decompression part 14. A reduction in equipment cost and production cost is thereby achieved, and a reduction in casting cycle time is also achieved.

摘要： A low-pressure casting device is provided with a holding furnace, a stoke, a pressure control device and a molten-metal level sensor. The holding furnace holds molten metal. The stoke supplies molten metal into a casting mold via a sprue. The pressure control device moves the molten metal in the stoke and fills the molten metal in the casting mold. The molten-metal level sensor detects a surface level of the molten-metal in the stoke. The stoke has a lower end immersed in the molten metal in the holding furnace. The low-pressure casting device is configured to correct filling of the molten metal in the casting mold in a next casting based on the height of the molten metal surface detected by the molten-metal level sensor.

摘要： A suction pressure casting method uses a casting device that includes a holding furnace for accumulating molten metal, a metal mold and a core forming a cavity, a molten-metal pressurizing tank that supplies a pressurizing gas, and a suction and exhaust tank for sucking and exhausting the inside of the cavity. A preset decompression pattern of a casting process is compared with a measured pressure pattern of the cavity and the core that is measured during actual casting. A corrected decompression pattern is calculated based on a difference therebetween. The preset decompression pattern at the time of the next casting is then corrected by using the corrected decompression pattern.

摘要： Provided is a low-pressure casting apparatus for stable casting without using feedback control even if a furnace body has a crack, and a low-pressure casting method using the same. A low-pressure casting apparatus fills a cavity with molten metal M through a guiding unit by introducing gas into a holding furnace for heating the molten metal M to apply pressure to a surface of the molten metal M. The holding furnace includes a casing, a furnace body accommodated in the casing, and a refractory layer disposed between the casing and the furnace body, the refractory layer having a pore structure. The low-pressure casting apparatus further includes a first gas supply unit for supplying to the furnace body the gas to apply pressure to the molten metal M and a second gas supply unit for supplying gas to the refractory layer.

摘要： An apparatus for manufacturing metal articles, in particular of light, alloy, includes a die including a pair of portions which can be separated to each other, which, in the closed condition, delimitate forging cavities having a shape corresponding to one or more articles to be forged, and a furnace adapted to melt the metal and to control the reaching by the molten metal of the hollow impressions of the die, as a result of overflowing through a duct connected to the furnace. A portion of the die includes, for each hollow impression, a movable punch adapted to apply a predetermined pressure on the relevant article during the forging step. Each punch is moveable in a manner independent from the other punches, and the apparatus includes a controller for controlling the pressure applied by each punch during the forging step, which allow to level the pressure applied by all the punches on the relevant article.
