Assembly in the form of a cluster of patterns for the consumable- (disposable-) pattern moulding of components, and method for assembling such patterns as a cluster

摘要

The present invention relates to an assembly in the form of a cluster of patterns for moulding components, and to a method for assembling such patterns as a cluster. This assembly, which consists of a spout (casting conduit) (30) from which at least one gate (32) projects, and of at least one pattern (20) fastened on one or more of these gates (32) by means of fastening means, is characterised in that these fastening means comprise at least one finger (23) of constant cross section projecting from each pattern (20) and capable of being force-fitted in a housing (32a) of corresponding shape provided on a gate (32). This invention applies to the production of patterns for moulding various components.
