    Channels or apertures are provided in a suitable area of the cores during the formation thereof in a first blowing machine, such that, on piling of the cores to form the block, and in the absence of additives between the contacting surfaces thereof, the apertures or channels are placed one adjacent another. Then a housing is defined, which affects the entire block in a longitudinal direction, and which subsequently molds a mixture of sand and a binder material, similar to a core in a second blowing machine. The material after hardening, acts as a coupling and stiffening arrangement between the cores forming the block.

    专利说明:

    The invention relates to foundry, in particular, to improvements in the formation of blocks of casting cores, such as, for example, used to cast cylinder blocks of engines or other machines that are provided by an optimal connection between several cores that make up the block without the risk of deviations size, and fast, simple and highly efficient operational process.
    The purpose of the invention is to improve the quality of the rod and simplify the process of joining its parts.
    FIG. 1 shows a part of a rod; in fig. 2 - the rod of the parts shown in FIG. one; in fig. 3-rod with a longitudinal groove filled with molding sand; in fig. 4 - cylinder block for a six-cylinder engine; in fig. 5 — rod corresponding to two cylinder blocks for a four-cylinder engine; 6 shows rods that form the engine cylinders and the cooling sleeve; in fig. 7 - molding machine for filling longitudinal grooves with molding sand.
    The cylinder block consists of parts 1 having grooves 2 filled with molding sand 3. The configurations of the parts are given as an example and can vary depending on the final configuration of the core block in accordance with the casting to be obtained.
    On the basis of the parts 1 having the grooves 2, the usual assembly shown in FIG. 2, where the corresponding grooves of each rod form one continuous continuous longitudinal groove, i.e. form a block similar to the usually made block of rods from parts 1. Their connecting surfaces 4 are in direct contact with each other, i.e. with layers of adhesive material and the specified longitudinal groove provided in said block, formed by grooves 2

    Parts 1. The molding mixture is introduced into the groove using a molding machine that manufactures the rod parts (Fig. 7). After filling the longitudinal groove of the core with the molding sand and hardening it, the external configuration of the rod is identical to that of a conventional rod, so that rigidity and compactness makes the rod easy to handle.
    The grooves 2 of each part have a narrowing of 5 or another irregular shape in the middle part to avoid a constant section of the groove. Moreover, the grooves 2 have a larger section in the bottom 6, than in the top 7, i.e. a dovetail type joint is obtained, which provides greater strength and rigidity of the rod. FIG. 5, the rod has, as a connection between the parts, an opening 8, located inside the rod and having a star-shaped configuration. This hole may have a different configuration. The connecting surfaces 4 may have protrusions 9 and their corresponding recesses to ensure good opening.

    the position of the rod parts relative to each other.
    FIG. 6, the grooves 10 are used to connect the parts of the rod, in the cavities of which the projections 11 of the part 12 are arranged. The parts of the rod are fastened by the manipulator 13 to form a block and transferred to the molding machine 14 to fill the groove or hole with molding sand.
