A mold for production of cast parts, comprising:
- two mold parts
- wherein at least one of the mold parts of the two mold parts is movable relative to the other to transform an open position into a closed position,
- wherein in the closed position the mold parts define a mold cavity fillable with liquid casting compound, and in their open position the mold parts enable removal of a cast part which has solidified by at least partial cooling, and
- a locking device,
- wherein the mold parts are lockable in the closed position by the locking device configured to join the two mold parts so as to be releasable, and
- wherein the mold parts are swingable around predeterminable axes in accordance with a casting program which is adjustable as to shape, time sequence and regions of the mold cavity which are to be wetted,
- wherein the two mold parts are respectively mold plates,
- wherein at least one of the two mold parts is movable with respect to the mold part from the open position into the closed position in an essentially straight line along a movement direction which is essentially perpendicular to planes of said mold plates, wherewith in the closed position the locking device which joins the two mold plates so as to be releasable brings about the locking of the mold plates in a pressed-together state such that a locking pressure is maintained while the mold plates are in their closed position,
- wherein the locking device includes a gas pressure spring configured to store energy to maintain a closing pressure which presses the mold plates together after the mold plates are closed and pressed together in a direction essentially perpendicular to the midplane of the mold plates,
- wherein the locking device further has
- a locking sleeve at one of the mold plates,
- a tension sleeve at the other mold plate, the tension sleeve is essentially aligned with the locking sleeve, and
- a movable tension bolt configured to interact with the locking sleeve and the tension sleeve,
- wherein the tension bolt is movable essentially in the movement direction perpendicular to the planes of the mold plates, and is axially mounted in a locking receptacle provided at one of the mold plates, with the movement of the tension bolt being subject to the action of closing pressure from the gas pressure spring,
- wherein the mold is part of a mold apparatus,
- wherein the mold apparatus is configured to automatically swing the two mold parts around the predeterminable axes, and
- wherein the tension sleeve houses the gas pressure spring and an entirety of the tension sleeve is provided outside of said other mold plate when the mold plates are in the open and closed positions.
