Abstract
PURPOSE:To reduce work done when a core mold is chocked and facilitate the work of choking, by a method wherein surface plates are retreated in parallel to a product to form uniform extracting gaps between the product, in the core mold. CONSTITUTION:When a screw rod 27 is turned, one of upper and lower nut members is moved upwardly and the other of the upper and lower nut members is moved downward whereby a connecting rod 43 is slanted. A pushing rod 41 is retracted inwardly by the slanting. The movements of surface plates 16, 16, effected by the retracting operation, are permitted by the inward deflection of deflecting members and respective surface plates 16 of a core mold 9 are moved in parallel and retreated inwardly whereby gaps for extraction are formed between the inside of a product shown by imaginary lines in a diagram. On the other hand, the screw rod 27 is turned into reverse direction upon assembling the frame whereby backup members 42 are adhered to the back surface of the deflecting members and inward deflections are precluded, therefore, the choking operation of the core mold is facilitated.
