Abstract

The invention relates to a foundry, in particular, to a casting tool for making castings in molds from raw sand or hardening molding sands. The aim of the invention is to expand technological capabilities and increase tool life. After compaction of the form, the restrictive plate 3 is disconnected from the U-shaped jacket 1 and the model plate 2 and joined with the same part of the form along the hollows and projections 19 of the jacket 1. The invention allows to obtain forms with dimensions in plan, large snap sizes, and It makes it possible to remove tooling elements from the molding mixture at any stage of casting production, in particular, before the operation of knockout. 2 hp f-ly, 10 ill.
