れることを特徴とするダイカスト鋳造装置。[Scope of Claim for Utility Model Registration] A cavity having a product part and a runner part for sending molten metal to the product part, a pressure reducing valve disposed at one end of the cavity, and an exhaust pipe having one end disposed in the pressure reducing valve. , a vacuum device disposed at the other end of the exhaust pipe, a die casting machine control panel for controlling the vacuum device, a molten metal detection sensor disposed in the runner section of the cavity, and a molten metal detection sensor disposed at the runner section of the cavity. In a die casting device comprising a pressure reduction control device that controls the pressure reduction valve and the die casting machine control panel based on a signal generated by is disposed, pressure reduction in the cavity is started in response to a signal from the one molten metal detection sensor, and the duration of the pressure reduction is determined from the difference in time during which each of the other molten metal detection sensors detects molten metal. A die-casting apparatus, characterized in that the decompression duration is calculated according to a calculation formula inputted in advance in the die-casting apparatus, and the decompression duration is corrected for each casting.
