  • Patent number: 4997025
    Abstract: A lining plate for the molding space of a molding machine is provided with functional openings such as sand supply openings and air-exhaust openings traversing the lining plate, the latter openings optionally provided with nozzle inserts. The lining plate is subdivided into two plate layers detachably fastened to each other, namely into a wear plate bordering the molding space and a carrier plate supporting the back of the wear plate. The mutually facing larger surface areas of the wear--and carrier plate are kept fully adherent to each other by magnet clamps and are additionally insured, in a detachably form-locking manner, against relative displacement with respect to each other. The lining plate allows a problem-free and comparatively cost-efficient restoration afer wear.
