Abstract

Improvements made to molds to form a fluid filter including: first and second body portions having contacting surfaces forming a dividing line and an evacuation device for the mold, said first and second body portions having a plurality of complementary semicircular cavities that correspond and that are axially separated, flat portions formed between said cavities, forming a conduit located in one of said first and second body portions in the axial direction of said semicircular cavities a passageway for the material of molding flow along it, and from it, in said multiplicity of semicircular cavities towards said dividing line, a core element arranged between said first and second body portions, said core element having a multiplicity of axially oriented grooves and radially outward, having said to grooves peripheral edges in contact with said flat portions, and a casting orifice device in one of said body proportions to facilitate the penetration of the molding material into said assemblies and from them to said annular cavities to form a filter for fluid.
