Abstract (en)

[origin: EP1952914A2] The crankcase-producing device is composed of fixed and movable half-molds forming a casting cavity (14, 21). The core (1) has apertures into which the holding projections (5, 6, 7, 8, 9, 10, 11, 12) on the mold parts extend, so that the core is fixed in position, thus forming the core for the water jacket of the crankcase.
