Definitions

  • the present invention relates to an apparatus for manufacturing items made of aluminum, aluminum alloys, light alloys and the like.
  • a casting technique which is known as low-pressure casting, wherein the liquid metal is made to rise from the furnace through a duct for introducing the liquid metal that exits upward in a die formed by two or more parts.
  • the aim of the invention is indeed to solve the above problems, providing an apparatus for manufacturing items made of aluminum, aluminum alloys, light alloys and the like, which allows to cast items that have a very compact structure without however having to use a dosage device to introduce the liquid metal, which is instead in practice dosed automatically by the apparatus.
  • an object of the invention is to provide an apparatus that allows to produce items without sprue and with considerably shorter times for obtaining the solidification step.
  • Another object of the present invention is to provide an apparatus that allows to provide, with a single casting operation, a plurality of parts that may optionally be different one another, obtaining correct dosage for each cast part.
  • Another object of the present invention is to provide an apparatus that by virtue of its particular constructive characteristics is capable of giving the greatest assurances of reliability and safety in use.
  • Another object of the present invention is to provide an apparatus that can be obtained easily starting from commonly commercially available elements and materials and is also competitive from a merely economical standpoint.
  • an apparatus for manufacturing items made of aluminum, aluminum alloys, light alloys and the like comprising, on a platen, a lower die and at least one upper die, a duct for introducing liquid metal that is connected to a furnace, said liquid metal input duct arriving from below and leading into said lower die, characterized in that said lower die forms at least one lower impression, which has at least one concave portion for introducing a dosed quantity of liquid metal, a male plug being associated with said upper die, said male plug being adapted to move with respect to said upper die and forming at least one upper impression that can be coupled to said at least one lower impression in order to determine the shape of the item being cast, said at least one upper die being closable onto said lower die and said male plug closing said shape and acting as a flow control element for the port that provides a connection to said input duct.
  • Figure 1 is a schematic sectional view of the apparatus, taken along a vertical plane, during the initial step of casting;
  • Figure 2 is a view illustrating the step for introducing the liquid metal in the lower die
  • Figure 3 is a view illustrating the step for dosing the liquid metal
  • Figure 4 is a view illustrating the step for the closure of the upper die onto the lower die
  • Figure 5 is a schematic plan view of a die with three impressions
  • Figure 6 is a schematic view of a safety shoe toe cap that can be obtained with the apparatus according to the invention. Ways of carrying out the Invention
  • the apparatus for manufacturing items made of aluminum, aluminum alloys, light alloys and the like comprises a platen, generally designated by the reference numeral 1, on which there is a lower die 2 with which an upper die 3 cooperates; said upper die can perform a translational motion toward and away from the lower die.
  • duct 10 for introducing liquid metal which arrives from below from a furnace 11 of the liquid metal which is preferably of the pressurized type; the duct 10 runs through the platen, where there are usual heating means 12, until it exits at the impressions 20 provided in the lower die.
  • the lower impression 20 has at least one concave portion 23 that allows to introduce therein a quantity of liquid metal that is a direct function of the geometry of the concave portion; therefore, by introducing the liquid metal and making it rise through the duct, by virtue of a pressing action applied by the furnace, it is possible to fill the concave regions or portions 23 with a quantity of liquid metal that in practice is dosed.
  • level sensors 30 it is possible to provide level sensors 30 to stop the rise of the liquid metal or it is optionally possible to preset the time and the pressure applied to the liquid metal so as to achieve dosed overflow of said liquid metal.
  • the level of the liquid metal is lowered again ( Figure 3), so as to provide precise dosage of the metal according to the position of the overflow ports 22 that form the region for the overflow of the liquid metal into the concave regions 23.
  • At least one male plug 8 is connected to the upper die 3, can move with respect to the upper die 3, and forms an upper impression 25, which in cooperation with the corresponding lower impression 20 forms the shape of the item being cast.
  • the specific example illustrates a toe cap 21 for safety shoes.
  • An important particularity of the invention consist in that after closing the upper die 3 onto the lower die 2 and after dosing the liquid metal, the piston 8, which moves with respect to the upper die 3, closes the port 24 for connection to the liquid metal input duct 10, thus achieving clear separation with respect to the column of liquid metal, which moreover, to perform dosage, had been made to descend in the channel 10, so as to place the free surface of the liquid preferably at the heated region.
  • the movement of the male plug 8 with respect to the upper die 3 applies pressure to the liquid metal, producing a particular compaction of said metal and thus obtaining parts that have considerable structural uniformity and improved mechanical strength.
  • the dosage of the metal is substantially produced by the shape of the lower impression and more particularly by the concave portion of the lower portion, allows to arrange around the same input channel impressions that are different one another and in which the liquid metal is always dosed correctly, said dosage being possibly different in each impression.
  • the male plug in practice forms a flow control element that closes the port for connection to the liquid metal input duct, avoiding the formation of sprue and also generating pressure on the liquid metal undergoing solidification, which helps to obtain a product with high-level structural and mechanical characteristics.
