Abstract (en)
[origin: EP0280675A2] Known moulds for crankcases have a large number of cores, which results in a more expensive core assembly and in an increase in the casting tolerances. In addition, due to unfavourable division of the outer mould, the freedom for shaping the crankcase is greatly restricted. In a mould for a crankcase of an in-line internal combustion engine with an outer mould resting on a pedestal of a base core, the base core having a pedestal section, a crank-space section and a main-bearing section, and with water-jacket cores and cylinder-bore cores, the above-mentioned disadvantages are overcome owing to the fact that the base core (1) has cylinder-bore cores (3) integrally formed in one piece, the pedestal section, the crank-space section and the main-bearing section being combined to form a single base-core part, adjoining which are the cylinder-bore cores, and that the water-jacket cores (12), the oil-space cores (18) and if need be a cover core (11) are mounted on the base core (1) thus formed. <IMAGE>
