Abstract
A device is provided for protecting the inner walls of casting molds, particularly molds of the permanent type which are filled by top pouring of the molten casting material thereinto, and for improving the surface quality of the castings formed in the mold. The device is formed from material which enables the device to be integrated into the casting formed in the mold and the protective device is configured with a bottom plate and a pair of laterally spaced upstanding side walls formed of sheet material. The protective device is placed in the bottom of the mold cavity and is located directly beneath the jet of molten casting material being poured into the mold. A wire lattice may be placed upon the protective device spaced above the bottom plate thereof or an upstanding tubular socket may be formed on the bottom plate.
