Molding system

A molding system for a low-pressure light alloy casting plant comprising a light alloy casting-injection system, wherein the molding system extends in height along a main axis and comprises a base region positioned at a bottom, in which the light alloy casting-injection system is at least partially housable, wherein the molding system comprises a mold comprising a lower half-mold and an upper half-mold, wherein the molding system further comprises:

• a lower fixed plate, on which the lower half-mold is housed, wherein the lower fixed plate and the lower half-mold are fluidly connectable to the light alloy casting-injection system;
• a movable plate on which the upper half-mold is housed;
• an upper fixed plate, positioned at a top of the movable plate;
• a movement group suitable for moving the movable plate along the main axis between a working position, in which the mold is closed, and a multiplicity of raised positions in which the upper half-mold is separated from the lower half-mold, the movement group comprising:
• an electric drive motor housed on the upper fixed plate;
• and
• transmission members operatively connected to the electric drive motor and to the movable plate suitable for transforming rotary motion of the electric drive motor into translational motion;
• a casting ejection group, housed on the movable plate, comprising:
• an electric ejector motor;
• ejection members operatively connected to the electric ejector motor, to the movable plate, and to the upper half-mold, the ejection members being movable by the electric ejector motor in an ejection position in which a casting is detached from the upper half-mold;
• and
• a command unit, operatively connected to the movement group and to the casting ejection group, suitable for commanding operation of the electric drive motor and of the electric ejector motor,
• wherein the lower half-mold comprises a plurality of slider elements positionable in a closed half-mold position and in an open half-mold position, wherein the molding system comprises a lower half-mold opening-closing group comprising a respective electric slider motor for each slider element of the plurality of slider elements.
