Definitions
- the invention relates to a method and an apparatus for Filling a casting tool with a molten metal according to the The preamble of claim 1 and claim 2.
- the invention has for its object to fill the To improve casting tool with a molten metal so that shorter cycle times with an improved quality of the casting can be united.
- this object is achieved by a method with the features of claim 1 and by a device with the features of claim 2.
- the basic idea of the invention is to melt the metal from the annular chamber into the mold cavity through a To displace the piston, which is slidable within the annular chamber is stored. This ensures that in the end of the filling cycle the further supply of molten metal is prevented.
- the piston advances the molten metal and pushes them out of the ring chamber into the mold cavity inside.
- the molten metal can therefore be supplied without turbulence, which reduces the formation of voids and the quality of the Casting is increased.
- the faster supply of the molten metal and the shorter ones Flow paths of the molten metal in the mold cavity a reduction the temperature of the molten metal supplied. this means a further reduction in wear and a Saving energy.
- the molten metal solidify faster, which on the one hand results in an additional shortening the total cycle time and also the dendrite growth reduced, so that the casting better mechanical Has characteristic values due to smaller dendrite arm distances.
- the annular chamber is provided with at least one piston which can be pressed into the volume of the annular chamber. This The piston closes the feed channel of the molten metal and presses the molten metal remaining in the ring chamber into the mold cavity.
- the method and the device can preferably be used rotationally symmetrical castings are used, for example for the production of alloy wheels for vehicles.
- the method and the device can be used with all known die casting processes, especially in low pressure casting machines, in back pressure casting machines, in press casting machines, with "squeeze” effect and with vacuum casting machines.
- the casting tool consists of a steel mold that is assembled is made of a lower tool part 10, an upper one Tool part 12 with a central insert 14 and slides 16.
- the lower tool part 10 is fixed on a base plate 18 assembled.
- the upper tool part 12 and its central insert 14 can be moved vertically. If necessary, the upper tool part 12 also integrally formed with the central insert 14 his.
- a jack 20 is guided.
- a retaining ring 22 is mounted, the lower tool part 10 coaxially encloses.
- the retaining ring 22 is radial to the outer circumference of the lower tool part 10 spaced so that between the outer circumference of the lower tool part 10 and an axially adjoining paragraph the base plate 18 on the one hand and the inner circumference of the retaining ring 22 on the other hand, a cylindrical annular chamber 24 is formed becomes.
- the annular chamber 24 is through the base plate 18 completed, with a fluid pressure channel 26 through the base plate 18 leads from below into the annular chamber 24.
- Down in the Annular chamber 24 is an annular piston 28 which supports the fills the entire horizontal cross section of the annular chamber 24 and has half the axial height of the annular chamber 24.
- the piston 28 is in the annular chamber 24 on its outer circumference and on its Inner circumference tightly guided.
- the piston 28 can by Pressurization via the fluid pressure channel 26 in the annular chamber 24 are pushed upwards.
- the piston 28 pushed up by several hydraulically operated jacks become.
- a feed channel 30 leads through the retaining ring 22 above the Piston 28 in the annular chamber 24.
- the feed channel 30 extends radially through the retaining ring 22 and rises axially from the outside inside.
- An inflow pipe 32 which is acted upon by a pressure piston is frictional and tight with a dome-shaped Mouthpiece to the radially outer end of the feed channel 30 then inserted into the retaining ring.
- the annular chamber 24 opens out at its upper end over its entire length Circumference and over their entire radial width in the mold cavity of the casting tool on its outer circumference.
- the annular chamber 24 opens into the formed by the lower tool part 10 and the sliders 16 Area of the mold cavity that is the outer rim flange of the wheel forms.
- the casting process is as follows:
- the upper tool part 12 with the central insert is located 14 in the raised upper position and the piston 28 lies at the bottom in the annular chamber 24, as in the right one Half of the drawing is shown.
- the annular chamber 24 is fed above the piston 28.
- the molten metal fills the annular chamber 24 and the mold cavity of the lower one Tool part 10, so that in the lower tool part 10th sets a characteristic bottom depth of the molten metal.
- the amount of molten metal supplied in this way is dosed according to the shape and weight of the cast body.
- Central insert 14 are driven down so that the tool is closed in the hub area. Then that will upper tool part 12 moved down and displaced and compresses the molten metal in the area of the spokes.
- the compression in the hub area is done by lifting the jack 20 from below into the middle hub area, in which the hub bore is inserted later.
- the feed channel 30 preferably does not open out in a circular manner Cross section into the annular chamber 24, but widens when Open into the annular chamber 24 delta-shaped in the circumferential direction the annular chamber 24. This distributes the through the feed channel 30 molten metal flowing into the annular chamber 24 more evenly on both sides in the circumferential direction and one laminar flow of the molten metal as it flows into the Annulus 24 is favored.
- the piston 28 can be a one-piece closed ring body be trained. It is also possible to use a piston 28 or to divide several radial joints, the thermal Take up extensions of the piston 28 in the circumferential direction.
- the piston 28 can also be divided into several (preferably 2) coaxially nested and axially displaceable Ring body may be divided, which pressurized separately and can be moved.
- the outer ring body is first applied to close the feed channel 30 and interrupt the metal supply.
- the inner ring body serves to melt the metal from the annular chamber 24 into the To displace mold cavity and especially in the pouring area condense.
- annulus 24 is not above hers entire circumference must flow freely into the mold cavity. Essential is that the largest possible inflow cross section exists between the annular chamber 24 and the mold cavity.
- annular chamber 24 is not necessarily must open on the outer circumference of the mold cavity, but can also open out in a radially central region. Where the annular chamber 24 opens into the mold cavity is expedient set according to the shape of the cast body. The farther the annular chamber 24 is arranged radially outside, the larger the inflow cross section and the more effective the invention Benefits used.
- the annular chamber 24 does not have to have a rotationally symmetrical shape, but can also take the form of a polygon, for example to have.
- the piston may be individual Piston body divided, which correspond to the individual polygon sides.
- the method according to the invention can also be used for non-rotationally symmetrical ones Castings are used.
