The utility model relates to a gate cup with a gravity casting booster assembly, which relates to the field of casting mould. The cavity in the gate cup is of inverted circular table type with large size and small size, and above the gate cup there are also gravity casting booster parts. The gravity casting booster parts include the indenter, the connecting part and the connecting part at the lower end of the indenter. The diameter of the connecting part is smaller than the diameter of the indenter. The lower end of the connecting part is provided with a pressure nozzle, which is inserted at the entrance of the gate cup under the external pressure, and the pressure nozzle is inserted at the gate. At the outlet of the cup, the liquid metal is subjected to pressure and filled in the gap between the supercharger of gravity casting and the inner wall of the gate cup. The gate cup uses gravity casting supercharger to exert pressure on the liquid metal in the gate cup, so that the liquid metal can fully contact the inner wall of the gate cup. The structure design is reasonable, the feeding capacity of the castings is improved, and the shrinkage defects of the castings are reduced.
【技术实现步骤摘要】
一种带重力铸造增压组件的浇口杯
本技术涉及铸造模具领域,特别涉及一种带重力铸造增压组件的浇口杯。
技术介绍
目前,金属液一般是经过浇口杯流入下面的模型中实现浇注成型,在重力铸造过程中有时因为压力不够,导致无法获得金属液的及时补缩,极易造成铸件的缩孔及缩松缺陷。
技术实现思路
针对现有技术存在的不足,本技术的目的是提供一种带重力铸造增压组件的浇口杯,该装置设计合理、结构简单,便于安装和维护。本技术所采用的技术方案是:一种带重力铸造增压组件的浇口杯,所述的浇口杯内的腔体呈上大下小的倒圆台型,其技术要点是,在浇口杯上方还设有重力铸造增压件,所述的重力铸造增压件包括压头、连接部及压嘴,压头下端设连接部,连接部的直径小于压头的直径,连接部下端设压嘴,压头在外界压力作用下插接在浇口杯的入口,压嘴插接在浇口杯的出口,金属液受到压力作用,填充在重力铸造增压件与浇口杯内壁之间的间隙处。上述方案中,所述的压嘴呈圆锥状。本技术的有益效果是:该带重力铸造增压组件的浇口杯,利用重力铸造增压件对浇口杯内金属液施加压力,使金属液能够与浇口杯内壁充分接触,该结构设计合理,提高了铸件的补缩能力,减少了 ...
