本発明は吹込式鋳型造型機に幇ける砂供給装置に関する
。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a sand supply device for a blow mold making machine.
従来、この種の砂供給装置は、鋳物砂のホッパとブロー
ヘッドの間にスライドゲートを摺動自在に嵌挿してホッ
パとブローヘッドの連通路を開閉するようにしているが
、摺動画に砂がかみ込んでそれらの摺動面を著しく摩耗
し、スライドゲート、とブローヘッドの間に隙間が生じ
、そのためにブローヘッドにエヤーを供給して鋳枠内に
鋳物砂を吹込む際、砂が吹らみエヤーとともにその隙間
部より噴出し鋳型の造型性を損うとともに周囲を砂で汚
し作業環境を悪くするなどの問題がある。Conventionally, in this type of sand supply device, a slide gate is slidably inserted between the foundry sand hopper and the blow head to open and close the communication path between the hopper and the blow head. The sand gets stuck and causes significant wear on the sliding surfaces, creating a gap between the slide gate and the blow head.As a result, when supplying air to the blow head and blowing molding sand into the flask, the sand gets stuck. There are problems such as the blowing air being ejected from the gap, impairing the moldability of the mold, and polluting the surrounding area with sand, making the work environment worse.

与する効果は著大である。In short, the present invention provides a chute member that can be inserted into and taken out of the blowhead through the sand supply port of the blowhead, above the blowhead that has an opening/closing gate in the sand supply port, and disposed at the bottom of the blowhead. The molding sand hopper, which is equipped with a valve for opening and closing the molding sand discharge passage at the upper position of the molding sand hopper, is movable up and down. If the empty space is designed in advance to be larger than the capacity of the molding sand left in the chute member, the molding sand will be reliably supplied into the blow head and the sand will be caught in the sliding area of the blow head and slide gate. The service life of the slide gate and blow head is significantly extended, the work environment is maintained in a good condition because the blown air does not blow out together with the molding sand from the gap, and good molds can be efficiently produced. It has excellent effects and its contribution to this type of industry is significant.
