SAND MOLD AUTOMATIC MOLDING LINE

PROBLEM TO BE SOLVED: To provide a sand mold automatic molding line in which molds are molded on upper and lower mold frames, and the upper and lower molds are registered for forming a mold, capable of preventing mold sand from firmly adhering to reference pin surfaces or reference bush inner surfaces on the upper and lower mold frames, maintaining a clean condition in the reference pin surfaces or the reference bush inner surfaces, and capable of positioning the upper or lower mold and a model for molding with high accuracy for a long period, for molding.SOLUTION: The sand mold automatic molding line is configured so that the reference pin surface or the reference bush inner surface on a subsequent mold frame is cleaned by a cleaning device during molding work, at a standby-position immediately in front of the molding machine. 【課題】上下の鋳枠それぞれに鋳型を造型した後、該上下の鋳型を型合わせして鋳型とする砂鋳型の自動造型ラインにおいて、上下の鋳枠の基準ピン表面或いは基準ブッシュ内面に鋳砂が強固に固着するのを予防して、基準ピン表面或いは基準ブッシュ内面の清浄状態を維持して、上鋳型或いは下鋳型と造型用模型とを長期間に亘り寸法精度良く位置合わせして造型可能にする、砂鋳型の自動造型ラインを提供する。【解決手段】前記造型機の直前の待ち位置において、後続する鋳枠の前記基準ピン表面或いは前記基準ブッシュ内面が、前記造型作業中、清掃装置よりクリーニングされる、砂鋳型の自動造型ラインにする。【選択図】図４
