Definitions
- the invention relates to a casting chamber for pressure casting of metallic materials in a die casting machine.
- a die casting machine has at least one movable and a stationary mold part, which are divided along a parting plane, and a mold cavity enclosed by these mold parts.
- This mold cavity to be cast metal is injected via a runner of the mold by means of a casting piston.
- the casting piston is displaceable in a casting chamber, into which the metal to be cast is insertable, by means of a drive along the longitudinal axis of the casting chamber.
- Such die casting machine is z.
- the production cost of such a highly loaded casting chamber is correspondingly high.
- the filling opening opposite surface of the casting chamber is affected and at a dosage from below, especially the transition region of the filling itself. A consequence are surface erosion, clamping the casting piston and changing the casting chamber.
- EP-A-477119 It is also known in sand molds to provide a sprue with a heavy-duty, replaceable insert (EP-A-477119). The same describes EP-A-703027.
- the invention has the object of providing a generic casting chamber in such a way that in comparison to the prior art, a better thermal insulation of the casting chamber is achieved.
- the invention is based on the recognition that a heat-optimized casting chamber can be achieved by passive measures.
- the casting chamber consists of an inner tube, on the outer surface of which an insulating layer is applied.
- the coated inner tube is covered by a steel jacket.
- the inner tube preferably with a wall thickness of only a few millimeters of a wear and heat-resistant steel and the outer steel shell of a cheaper tempered steel.
- the inner tube is preferably coated with a thin ceramic layer, for example made of ZrO 2, and is preferably shrunk into the steel jacket.
- the layer is applied by thermal spraying, eg plasma spraying.
- a ceramic wear protection arrangement is provided in the inner tube below the filling opening for the molten metal to be cast, which is intended to prevent "washing out” of the inner wall of the inner tube
- the wear protection arrangement can be designed as a plate or disk, for example, and closes flush with the surface of the inner tube.
- the casting piston To the thermal benefits of a heated casting chamber, d. H. To use less pre-solidification in the casting chamber and the resulting higher component quality and lower rejects share, the casting piston must be moved at a higher temperature in the casting chamber. The temperature is adjusted so that, although a sufficiently thick ring of the melt solidifies (seal) but on the other hand, the lowest possible pre-solidification is ensured in the casting chamber. This requires the most accurate possible adjustment of the temperature of the casting piston at high cooling capacity, respectively. an intensive surface contact of the cooling medium with the casting piston.
- the casting piston is cooled from the inside, preferably a water mist, wherein the evaporation enthalpy of the drops is used for the cooling.
- Preference is given to a temperature below 400 0 C, so that the casting flask is maintained at a temperature below 400 0 C.
- the temperature of the casting piston in a range of about 15O 0 C moves below 400 ° C.
- the invention will be described below in an embodiment with reference to a drawing.
- the drawing shows a casting chamber in section (schematized).
- a stationary mold carrier is provided with a mold half attached thereto in a conventional manner.
- a casting chamber 1 is arranged, in a known manner by means of a casting piston a not shown but familiar to those skilled drive and control device along the longitudinal axis of the casting chamber 1 is displaceable.
- the metal to be cast passes via a filling opening 2 into the casting chamber 1.
- the casting chamber 1 consists of three layers.
- the inner layer forms an inner tube 3 with a wall thickness of a few millimeters, z. B. 5 mm, made of a high-strength steel, on the outer surface of which a thin, thermal insulation layer 4 of z. B. ZrO2 is applied.
- the insulation layer 4 is applied by plasma spraying.
- a ceramic wear protection ring 6 is embedded in the inner tube 3 on its opposite side.
- the coated inner tube 3 is shrunk into a cylindrical, outer steel shell 5 made of a tempering steel.
- the temperature of the casting chamber 1 is set to a value between 400 0 C and 700 0 C depending on the material to be cast.
- Superheated water mist in which the temperature of the casting piston is also dependent on the material adjusted to a value between 150 ° C and 400 0 C is fed with pressure into the interior of the casting piston through a carburetor.
- the casting piston is made of steel in combination with copper and / or titanium alloys.
