MOLD SHOE FOR INTERLOCKING BLOCK

PURPOSE:To prevent adhesion of a part of a molding material to a mold shoe at the time of molding an interlocking block by a method wherein a specular Cr-plated layer having specific surface roughness and hardness is formed on a surface of a mold shoe matrix. CONSTITUTION:On a surface of a mold shoe...

Zusammenfassung:	PURPOSE:To prevent adhesion of a part of a molding material to a mold shoe at the time of molding an interlocking block by a method wherein a specular Cr-plated layer having specific surface roughness and hardness is formed on a surface of a mold shoe matrix. CONSTITUTION:On a surface of a mold shoe matrix 2 made of an SCM material, a specular Cr-plated layer 3 having a surface roughness Rmax not more than 5mum and a hardness HV not less than 800 is provided. In the production of an interlocking block out of a concrete as a molding material 6 using this mold shoe 2, the occurrence number of a molding operation interruption caused by the adhesion of the molding material 6 to the mold shoe 2 is remarkably reduced, and also the life of the mold shoe 2 is enhanced.
