Abstract

PURPOSE: To enable the automatic inspection of defective molds whose molten metal pouring cups are closed by supporting an inspection rod vertically movably to a detecting head, inserting the inspection rod into the pouring cup and providing a means of detecting its displacement.
CONSTITUTION: When a mold 3 is carried to below a detecting head 9, a piston rod 7 is lowered to push down the detecting head 9, then the inspecting rod 15 inserted into the detecting head 9 also descends and its end 16 enters a molten metal pouring cup 4. When the end 16 reaches the specified position, it contacts the protrusion 10 on the detecting head 9 side wall and a limit switch 11 detects the descending position of the detecting head 9. When sand crumbling 21 has occured in the molten metal pouring cup 4, the inspection rod 15 stops in that position and only the detecting head 9 descends down to the specified position, and its collar 17 contacts a displacement-detecting limit switch 20. Thereby, the occurrence of the sand crumbling 21 in the molten metal pouring cut 4 of the mold 3 is detected.
