The invention relates to a casting mould for producing helical cast bodies (1), in particular coils, springs or spirals, having a mould (10) in the form of a permanent mould which determines the outer contour of the helical body and consists of a ceramic material or is coated by a ceramic material; a supporting tool (8), which supports the mould (10) from outside; and a mould core (12), which defines the continuous opening within the helical body (1) and consists of a ceramic material or is coated by a ceramic material, the mould core being formed in particular as a core puller.

A pair of main molds forming an outer peripheral face of a piston and a pair of side cores forming the pair of cutout recess parts of the piston are prepared, the main mold and the side core are set so as to form a cavity corresponding to the piston, the cavity is charged with molten metal, and when the side core is moved downward and in a direction away from the central axis of the piston so as to carry out mold release from the cutout recess part after the piston within the cavity has solidified, the side core is tilted in a direction in which an upper end thereof approaches the central axis of the piston. Thus, it is possible to release a core smoothly from a cutout recess part without it biting into an inside face of the cutout recess part.

An apparatus for molding process includes a mount including a base, a support on the base, first and second side columns, and a mounting member moveably on tops of the first and second columns; pneumatic first and second half molding assemblies for forming a mold; and first and second auxiliary devices cooperating with a die to insert the mold for molding. There are further provided second cooling devices, first and second lifting devices, first and second lowering devices, and a control device.

A casting mould for producing a casting formed from a light metal alloy, in particular a housing for an electric drive for a motor vehicle. The casting mould advantageously has at least one sand core which is designed and arranged in the casting mould in such a way that the at least at least one sand core can be completely surrounded, at least in sections, in a circumferential direction by a light metal melt with which the casting mould is filled to form the casting. It is advantageous to be able to produce a casting in which, for example, a cooling channel is incorporated. It is not necessary to drill a hole to form a channel. Furthermore, the invention relates to a process for manufacturing a casting made of a light metal alloy, in particular a housing for an electric drive for a motor vehicle.

A method for manufacturing a blade for a turbine engine, including a root connected to a vane extending in a longitudinal direction, includes providing an assembly having a first part intended to form a root of the blade and a projecting second part projecting in the longitudinal direction from the first part; providing a mold comprising a first impression and a second impression delimiting together a cavity, said cavity comprising a first space and a second space; arranging the first part in the first space of the cavity and the second part in the second space of the cavity; and forming a third part by injecting an aluminium-based alloy in the cavity.
