し易かった。However, in this type of device, when the molten metal is filled into the cavity, the water such as 111 type agent sprayed into the cavity is vaporized by the heat of the molten metal, and as a result, it runs first inside the cavity. The molten metal scatters like shotguns or becomes a mist and passes through the air vent (2) and enters the valve (
5) is often passed. As a result, the molten metal that scatters like shotguns or becomes atomized during casting may accumulate inside the gas venting device (3) or the valve (5), causing malfunction of the gas venting device (especially the valve (5)). ) related malfunctions) were likely to occur.

。And, in the third invention, by devising the part from the cavity (4) to the vertical runner part (9),
In addition to preventing the molten metal that scatters like shotguns or becomes mist from escaping into the vertical runner part (9) in the cavity (4), it also prevents the molten metal that has entered the cavity first. This is to prevent discontinuity with the subsequent large amount of molten metal. That is, a horizontal runner part (8) is formed between the carrier and tee (4) and the vertical runner part (9), and the horizontal runner part (8) and the cavity (
A plurality of approximately rectangular sump sections (11) are formed between the sump sections (11) and the horizontal runner sections ( 8)

ス抜き装置内乃至金型（１）外へ噴出することはない。When the molten metal enters the cavity (4), the gas in the cavity (4) flows from the inlet (11a) of the sump (11) through the air vent (2) due to the force of the gas to the gas venting device (3). At the same time as the molten metal is discharged from the mold (1) through the valve (5) of Entrance (
lla) through the air vent (2) to the degassing device (
3), by colliding with the inner walls of the sump section (11), horizontal runner section (8), vertical runner section (9), and bypass (7) countless times. , the mist-like molten metal finally passes through the valve of the degassing device (3).
) will not be passed. On the other hand, the molten metal that has entered the cavity (4) enters the inlet portion (11a) of each sump (11).
It enters the sump (11), is gathered up by the tangential horizontal runner section (8) that fully fills this sump (11), and continues to the vertical runner section (9), where it is subjected to a large inertial force. As a result, it quickly collides with the valve head (5a) of the valve (5) of the gas venting device (3) and closes the valve (5). As a result, the bypass (7) branches off from the vertical runner section (9).
) The molten metal that has bypassed the valve (5) is completely blocked by the valve (5) and will not spout out into the gas venting device or out of the mold (1).

至金型外へ噴出する恐れはなくなる。<Effects of the Invention> As is clear from the above explanation, according to the first invention,
Even if the molten metal that led the way up the vertical runner becomes discontinuous with the large amount of molten metal that follows and there is no inertial force to close the valve of the degassing device, the bypass itself is more effective than conventional devices. Coupled with the long structure, the short horizontal part that makes up the bypass acts as a pool, and the presence of the short inclined part causes turbulence in the flowing molten metal, making the flow even stronger. Due to the delay, before the first molten metal reaches the valve of the degassing device, a large amount of molten metal comes up the vertical runner and collides with the valve head of the degassing device valve, closing the valve. Therefore, there is no possibility that a part of the molten metal will be ejected into the gas venting device or out of the mold.

が長期に渉って作動不良を起す恐れがなくなる。Furthermore, according to the second invention, even if the molten metal that flies off like a bullet or becomes atomized inside the cavity reaches the vertical runner section, it will not be able to reach the vertical runner section while passing through the approximately U-shaped bent section. It collides with the inner wall many times and solidifies, and almost never reaches the degassing device, eliminating the risk of the degassing device malfunctioning over a long period of time.

くなる。Further, according to the third invention, even if molten metal scatters like shotguns or becomes atomized within the cavity, it will collide with the inner wall of the sump section and the inner wall of the horizontal runner section countless times and solidify. Therefore, it almost never reaches the vertical runner section, the bypass, and even the degassing device, eliminating the possibility that the degassing device will malfunction over a long period of time. Moreover, the molten metal that has entered the cavity is first collected in a small number of horizontal runner sections that fully fill multiple sump sections, and then continues to the vertical runner sections, so that the molten metal enters the cavity at the beginning. The molten metal that came in after being cut,
It is possible to prevent discontinuity with the subsequent large amount of molten metal, and as a result, the valve of the gas venting device can be closed quickly and reliably, and there is no fear that the molten metal will spout into the gas venting device or out of the mold.
