Abstract

PURPOSE:To pack efficiently and uniformly a prescribed amt. of sand into a casting mold by connecting a gas vessel and blowing nozzles via a selectro valve and opening the selector valve at the same instant when an open/shut plate is opened. CONSTITUTION:A prescribed amt. of the sand is charged into a sand vessel 5 and a gas kept under a prescribed pressure is introduced into a gas vessel 8. An air cylinder 6 is then actuated to open/shut plate 7 to the right and left and at the same time the selector valve 10 is opened. The gas is blown instantaneously from the nozzle 9 so that the prescribed amt. of the sand is quickly packed from the vessel 5 into the molding flask 1. The vessel 5 and the flask 1 are separated upon ending of sand packing and a device for supplying a curing gas is connectted to the molding flask to cure the sand. The casting mold is thus produced.

In Fig. 1, a model 4 is placed in a chamber 3 formed by a mold frame 1 and a suction box 2, and the space in the chamber 3 around the model is filled with sand to form a mold. An apparatus for manufacturing is shown. In the sand filling device for molds of the present invention, a sand container 5 is placed on the upper part of the mold l.
An opening/closing plate 7 that is opened and closed by an air cylinder 6 is provided at the bottom of the sand container 5 to form a bottom plate of the container 5.A blowing waste container 8 is provided adjacently around the sand container 5.
Also, a large number of blowing nozzles 9 are provided in the sand container 5, and these nozzles 9 are connected to a gas container 8 via a switching valve 10. In the figure, 11 is a valve for introducing a predetermined amount of gas into the gas container, 12 is a suction 1, 13 is a vent hole provided in the suction box 2 or the model 4, and 14 is a port for introducing sand. In Figure 0, which shows the opening, the pressure gauge, suction pump, pressure control device, etc. are omitted. In the sand filling device of the present invention, a predetermined amount of sand is put into the sand container 5, gas at a predetermined pressure is introduced into the gas container 8, and the air cylinder 6 is operated to move the opening/closing plate 7 from side to side. When the switching button tlO is opened at the same time as the opening, gas is instantly blown from the nozzle 9, and a predetermined amount of sand is quickly filled into the form l from the sand container 5.

図示の如くブロー用ノズル９は複数箇設けることが好ま
しく、又ガス容器８は複数の大径のパイプを小径のパイ

に便利である。As shown in the figure, it is preferable to provide a plurality of blowing nozzles 9, and if the gas container 8 has a plurality of large-diameter pipes connected with a small-diameter pipe, it is convenient to hold the required amount of blowing gas. .

本発明の充填装置を使用して、砂の充填が終了した後は
、砂容器５と型枠ｌを分離し、型枠に硬化用ガス供給装
置を接続して硬化して鋳型を製造することが出来る。After sand filling is completed using the filling device of the present invention, the sand container 5 and mold frame 1 are separated, and a curing gas supply device is connected to the mold frame to harden it and manufacture a mold. I can do it.
