  • Apparatus for measuring strength of a mold and for pressing marks on the mold
    Patent number: 5887638
    Abstract: A method for measuring the strength of a cavity surface (2a) of a mold (2) and for simultaneously pressing one or more marks (21a, 21b) in the cavity surface (2a) is disclosed. Such marks (21a, 21b) formed in a cavity surface of a mold are transferred to a cast when it is produced from the mold, and the transferred marks appearing on the surface of the cast display some information. The method includes the steps of pressing one or more marks (21a, 21b) in a cavity surface of a mold by using a press member (14) that has a pressure sensor (15), and measuring the strength of the mold (2) by detecting a reaction force by the pressure sensor (15) that acts on the press member (14) when the press member presses the mark in the cavity surface of the mold.
