The utility model discloses an electric vehicle motor shell cooling water course casting psammitolite, it is shaping with the preparation of tectorial membrane sand through the core shooting machine, form including at least three rings casting backs the spirochaeta of cooling water course, spirochaeta head and the tail both ends have the column body that the casting back formed cooling water course cooling water outlet and inlet, the main reference column of fixed psammitolite when being equipped with the casting on the outer wall of spirochaeta respectively. The utility model discloses a preparation process had both been simplified to the integral type structure, and material saving can guarantee the psammitolite again and fix a position the accuracy in the mould, and there is not eccentric phenomenon in the cooling water course that forms, is favorable to the improvement of psammitolite yield yet. 本实用新型公开了一种电动汽车电机壳冷却水道浇铸砂芯，通过射芯机将覆膜砂制作成形，包括至少三圈浇铸后形成所述冷却水道的螺旋体，螺旋体首尾两端分别具有浇铸后形成冷却水道冷却水进出口的柱状体，在螺旋体的外壁上设有浇铸时固定砂芯的
