The utility model discloses a casting structure for precision casting, which comprises an upper mould box, an upper mould sand mould, a lower mould box, a lower mould sand mould and a fastening mechanism. The upper mould box fits with the upper mould sand mould, the lower mould box fits with the lower mould sand mould, the upper mould box is relative to the lower mould box, and the upper mould box is provided with a gate. A runner is arranged at the opposite part of the mould and the gate, and a pouring cup is fixed on the gate. A positioning groove is also arranged on both sides of the inner wall of the upper mould box and the lower mould box. A positioning groove is arranged on the contact surface of the upper mould box and the lower mould box, and a positioning pin is arranged on the contact surface of the lower mould box and on both sides of the upper mould box and the lower mould box. The fixed arm is fixed, and the fastening mechanism is fixedly connected with the fixed arm. The utility model adopts the pouring structure of the above structure for precision casting, which has simple structure, stable and reliable non-expanding box, and is surrounded by upper and lower mould boxes, so as to reduce the amount of moulding sand and hot metal, at the same time, the casting cost and deformation are small, and the surface is smoother.
【技术实现步骤摘要】
用于精密铸造的浇注结构
本技术涉及铸造
,尤其是涉及一种用于精密铸造的浇注结构。
技术介绍
现有铸造技术中,通过型砂进行铸造时,由于型砂容易发生涨箱,使得铸造件发生变形,为了后续加工,不得不增加加工余量,增加铁水的使用量,同时型砂厚度大,也增加了型砂的使用量,加工成本高。
技术实现思路
本技术的目的是提供一种用于精密铸造的浇注结构,结构简单,固定可靠不涨箱,外包有上模箱与下模箱,减少型砂和铁水用量,同时铸造成本变形小,表面更加光滑。为实现上述目的,本技术提供了一种用于精密铸造的浇注结构包括上模箱、上覆模砂型、下模箱、下覆模砂型以及紧固机构,所述上模箱与所述上覆模砂型相贴合,所述下模箱与所述下覆模砂型相贴合,所述上模箱与所述下模箱相对设置,所述上模箱上设置有浇注口,所述上覆模砂型与所述浇注口相对处设置有浇道,所述浇注口上固定有浇杯,所述上模箱和所述下模箱内壁两侧还设置有覆模砂定位槽,所述上模箱上与所述下模箱的接触面设置有模箱定位槽,所述下模箱上与所述上模箱的接触面设置有定位销,所述上模箱与所述下模箱两侧设置有固定臂,所述紧固机构与所述固定臂固定连接。优选的,所述紧固机 ...
