Embodiment Construction

[0040] figure 1 A part of a casting device 1 for die-casting a metal melt 2 such as a magnesium melt or an aluminum melt is schematically shown. The casting device 1 has a casting chamber 4 which can be filled by a melt reservoir (not shown) via a melt valve 19 . The melt 2 is pushed from the horizontally oriented casting chamber 4 via a hydraulically moved casting piston 6 advancing horizontally into a melt channel 11 and is acted upon with pressure.

[0041] The melt channel 11 is surrounded by a heating means 5 in the form of a coil which prevents the melt 2 from cooling. From the heated melt channel 11, the melt 2 reaches the valve chamber 8 of the casting valve 7 through a melt channel interface 12 ( figure 2 ) and from there via the valve outlet 10 into the casting cavity 3 . The casting cavity 3 itself is formed by two casting mold half-shells 15, 16 and in a known manner by a negative mold enlarged by the shrinkage allowance (Schwindma β) of the casting to be produ...

Abstract

A casting valve configured to supply a melt of a casting device includes a valve housing including a melt channel connection as an inlet and a valve outlet as a run-out. A melt channel is configured to be pressurizable via a casting pressure. A valve compartment is configured to receive the melt. The valve compartment is connectable via the melt channel connection with the melt channel. A closing device is configured to modify a cross-sectional surface of the valve outlet. A post-compression piston is configured to post-compress the melt after a completion of a mold filling.

Description

technical field [0001] The invention relates to a casting valve for supplying melt to a casting device, said casting valve having: a valve housing with a melt channel connection as inlet and a valve outlet as outlet; A valve chamber is used to receive the melt; a closing device is used to change the cross-sectional area of ​​the valve outlet. The invention also relates to a casting device having a casting valve of this type and to a casting method for producing cast parts with the casting device. Background technique [0002] Numerous measures are known from the prior art in order to influence the mold filling process of the mold cavity of the cast part. A defined sprue speed (Anschnittgeschwindigkeiten) and gating system is used for each melt type. Since a maximum sprue speed must not be exceeded, the cross-section of the sprue face and thus that part of the gating system which enables separation of the casting part from the die-casting tool after the casting process need...
