Apparatus for measuring strength of a mold and for pressing marks on the mold

An apparatus for measuring strength of a cavity surface of a sand mold and for simultaneously pressing in the cavity surface a mark that displays some information, comprising:

• a press member configured to press the mark in the cavity surface of the mold;
• a press member positioning unit coupled to the press member and configured to move said press member over a desired location on the cavity surface and to press said press member against the location on the cavity surface, thereby causing the press member to press the mark in the cavity surface at said location;
• a pressure sensor coupled to said press member and configured to generate data indicative of a reaction force exerted on said press member by the cavity surface of the mold when said press member presses said mark in said cavity surface of the mold;
• and
• calculating means coupled to the pressure sensor and configured to calculate strength of the cavity surface of the mold by processing the data generated by the pressure sensor.
