一种重力浇铸模具无烟浇注工艺
摘要：
本发明提供一种重力浇铸模具无烟浇注工艺，在重力浇铸模具上采用暗冒口设计，所述重力浇铸模具一端为进水口，所述进水口上设有所述主冒口，所述重力浇铸模具上设有出气口，所述出气口上设有所述暗冒口，所述暗冒口通过导通部与所述重力浇铸模具的管腔相通，所述主冒口和所述暗冒口之间通过补缩通道连接，所述补缩通道通过凹槽贯通所述主冒口和所述暗冒口，所述凹槽的横截面积与所述暗冒口的横截面积相匹配；本发明涉及的这种重力浇铸模具无烟浇注工艺，废气大部分停留在型砂之中，再经过环保砂处理设备，减少废气排放术人员深入现场。
摘要（英）：

The invention provides a smokeless casting process for a gravity casting mould. A blind feeder design is adopted on the gravity casting mould; a water inlet is formed in one end of the gravity casting mould; a primary feeder is arranged in the water inlet; a gas outlet is formed in the gravity casting mould; the blind feeder is arranged in the gas outlet, and is communicated with a tube cavity of the gravity casting mould through a conducting part; the primary feeder and the blind feeder are connected through a feeding channel; the feeding channel is communicated with the primary feeder and the blind feeder through a groove; the cross section area of the groove is matched with that of the blind feeder. According to the smokeless casting process for the gravity casting mould disclosed by the invention, most of waste gases are kept in a sand mould, and the emission of waste gases to sites of the operation staff is reduced after the waste gases are processed by environment-friendly sand treatment equipment.
