Abstract

A system for making sand molds with one or more cores, comprising a machine in which mold sections are successively manufactured between a pair of opposing model holder plates in a stationary molding chamber, which is rigidly attached to a conveyor grid on which the mold sections, when separated from the model plate next to the conveyor grid, are pushed by a movement transmitted through the second model plate to be successively placed together to form a chain of closed molds, and a mask of males intended to receive the male, or the males, and movable from a receiving position to a position opposite to the rearmost mold section of the chain and from there in the axial direction of the chain to introduce the male, or the males, in the mold section, characterized in that next to the mold chain there is a core manufacturing machine that has a core box with a vertical joint surface and in which a core network is produced consisting of one or more cores with one or more associated discharge lines, the geometric axis of the core box being perpendicular to the parallel joint surface to the geometric axis of the mold chain, and because the core mask, in its reception position, is aligned with a section of the mentioned core box in such a way that the core network can be automatically transmitted from the core section. the core box to the core mask, and that the core mask is controlled in such a way that its movements between the position of reception and the position of delivery of cores in alignment with the last mold section formed in the chain of molds on the conveyor grid are translational movements partly in the axial direction and partly in the direction perpendicular to it.
