一种车钩提杆座覆膜砂模具
摘要：
本实用新型提出了一种车钩提杆座覆膜砂模具，模具包括凸模、凹模、浇口浇道和活块，在所述凸模和所述凹模的上表面分别开设有凸模型腔和凹模型腔，所述凸模型腔和所述凹模型腔在合模后形成砂壳型腔，所述凸模型腔包括第一型腔和第二型腔，所述凹模型腔包括第三型腔和第四型腔，两个所述活块安装在所述第一型腔内。其有益效果是：本实用新型经过合理的型腔、浇道以及射砂口的设置，可以增加砂壳的成品率，提高铁水浇铸时车钩提杆座的成品率。(ESM)同样的发明创造已同日申请发明专利
摘要（英）：

The utility model provides a precoated sand mold for a car coupler lifting rod seat. The die comprises a male die, a female die, a sprue runner and a loose piece, a male die cavity and a female die cavity are formed in the upper surface of the male die and the upper surface of the female die respectively. The male die cavity and the female die cavity form a sand shell cavity after die assembly, the male die cavity comprises a first cavity body and a second cavity body, the female die cavity comprises a third cavity body and a fourth cavity body, and the two movable blocks are installed in thefirst cavity body. The casting mold has the beneficial effects that through the reasonable arrangement of the mold cavity, the pouring gate and the sand shooting opening, the yield of a sand shell canbe increased, and the yield of a car coupler lifting rod seat during molten iron casting is improved.
