Abstract

PURPOSE:To cut a molten metal in the part of a desired sprue length and to prevent the generation of inconveniences such as clogging and galling in the sprue part of a die by measuring the cutting temp. with a temp. sensor. CONSTITUTION:The molten metal in a furnace passes through a stoke 4 and is poured into the product cavity 10 of the die 7 when the pressurized gas is supplied into the furnace through a pressurizing gas inlet and outlet port 6 after die clamping. The signal from a control device 21 is transmitted to a valve 20 of an air supply source 19 and a valve 20 is opened when a thermocouple 13 detects the solidifying temp. of the molten metal 2 near the sprue part 12. The pressurizing air is conducted through an air supply hole 17 to a ring groove 14 and is discharged through an air discharge hole 18 on the opposite side; at the same time, part thereof is introduced through a ring groove 14 and air injecting slit 16 having 0.2-0.3mm depth into the cavity of the sprue part. Blows are generated in the part where the air is introduced and the vertical bond connecting said part is weakened. The molten metal in the mid-way of the solidification is cut from the part where the air is injected and is returned by the own weight into the molten metal 2 in the furnace.

Pressure of 1 atmosphere or less is applied to the surface of the molten metal in the molten metal holding furnace using compressed air or inert gas to push the molten metal up.
The low-pressure casting method, in which molten metal is cast from below through a stalk into a mold placed on top, is well known and is mainly used for casting light alloy castings.

In this low-pressure casting method, the molten metal filling the mold is
Solidification begins at the upper part far from the sprue, and the sprue solidifies last. Therefore, if the pressurization is stopped immediately after the upper part of the sprue has solidified, part of the sprue and the molten metal in the stalk will fall into the furnace due to gravity and return to the molten metal in the molten metal holding furnace.

By the way, if the time to release the pressure in the molten metal holding furnace is delayed, the solidification length of the molten metal at the sprue will become longer, making it difficult to remove the product inside the mold from the mold, and the mold may become clogged. , problems such as mold galling occur. on the other hand,
If the pressure in the molten metal holding furnace is released too quickly, the molten metal in the mold has not yet completely solidified, resulting in insufficient pressurization and causing casting defects such as shrinkage cavities.
