Claims (2)
- 鋳物砂を収容する収容部と該収容部に連通するように設けられたブローノズルとを有するブローヘッドと、該ブローヘッドの収容部内に加圧気体を供給する加圧気体供給装置とを備え、該加圧気体供給装置により上記収容部内に加圧気体を供給することで、該収容部内の鋳物砂を上記ブローノズルを介して成形型のキャビティ内に吹き込み充填するように構成された鋳型造型装置であって、
上記収容部内の鋳物砂量を検出する鋳物砂量検出手段を備え、
上記加圧気体供給装置は、上記収容部内に供給する加圧気体の圧力を、加圧気体の収容部内への供給中に、1回低圧から高圧へ不連続に上昇させるように構成されているとともに、上記低圧及び高圧の圧力レベルをそれぞれ変更する圧力変更手段を有し、
上記圧力変更手段は、上記鋳物砂量検出手段により検出された鋳物砂量に基づいて上記低圧及び高圧の圧力レベルをそれぞれ変更するように構成されていることを特徴とする鋳型造型装置。 - 請求項1記載の鋳型造型装置において、
上記加圧気体供給装置は、低圧の加圧気体を貯蔵する低圧タンクと、高圧の加圧気体を貯蔵する高圧タンクと、上記低圧タンクの低圧の加圧気体から上記収容部内に供給し始めて、その後に上記高圧の加圧気体を上記収容部内に供給する供給手段とを有していることを特徴とする鋳型造型装置。
