Description

Technical Field

[0001] The utility model belongs to the technical field of die-casting die sets, and particularly relates to an exhaust device for a die-casting die set. Background Art

[0002] Patent Publication No. CN 210547993U discloses an exhaust device for a die-casting die set, belonging to the technical field of die set manufacturing. It solves the problem that the high-temperature and high-pressure molten metal or gas of the existing die-casting die set for automobile sheet metal parts is likely to be directly discharged outside the die set through the exhaust groove and cause injury. In the exhaust device of this die-casting die set, the upper surface of the die-casting cavity block in the cavity has die-casting tooth grooves, and exhaust holes are vertically arranged downward on the die-casting cavity block at the middle position between adjacent two die-casting tooth grooves. An exhaust channel is arranged in the fixed die, and the upper end of each exhaust hole is communicated with the cavity, and the lower end of each exhaust hole is communicated with the exhaust channel. One end of the exhaust channel is provided with a buffer device for adjusting the air pressure in the exhaust channel, and the other end of the exhaust channel is provided with a connection structure communicated with the external air pressure. The utility model avoids the high-temperature and high-pressure molten metal or gas from directly spraying outside the die set to cause injury and prevents the occurrence of safety accidents. Although the above exhaust device can effectively exhaust gas, when replacing different sizes of exhaust holes for different die-casting raw materials, it is necessary to replace different die sets and corresponding sizes of exhaust holes during the die-casting process of some raw materials, resulting in a small die-casting use range and poor flexibility of the die set. Therefore, we propose an exhaust device for a die-casting die set. Summary of the Utility Model
