Improvements in the machines for manufacturing casting cores, of the type that forms these cores by sand-resin injection, and which comprises a feed tank, arranged between mold plates where the core is formed, and a connection of the feed tank to a source of compressed air for injection, characterized by the fact that behind the mold plates there are gas, butane or similar lighters or infrared radiators of the butane type, as heating elements of these plates and of the molds that they are placed therein, heating the mold through the plates and the rear face thereof, the plates comprising on these faces heat concentrators constituted by upper U-shaped or similar visors that tend to maintain the Calorific radiations at the height of the plate making it difficult to climb.
