Mold machining supporting device convenient to adjust

The supporting device comprises a base, four sets of supporting columns are welded to the four corners of the top face of the base, threaded holes are formed in the top faces of the supporting columnsthrough punching and tapping, screw rods are rotatably connected into the threaded holes, and extension rods are welded to the top ends of the screw rods. And a buffer pad is glued at the top end ofthe extension rod. Through the arrangement of the supporting column, the threaded hole, the screw rod and the extension rod, the external leveling device is placed on the bottom plate, the screw rod is rotated according to leveling data to drive the extension rod to ascend or descend for height adjustment, the plane of the bottom plate is leveled, machining errors caused by plane errors are avoided, and the leveling device is practical and suitable for wide application and popularization. 本实用新型公开了一种方便调节的模具加工用支撑装置，包括底座，所述底座顶面四角焊接有四组支撑柱，所述支撑柱顶面通过打孔并攻牙有螺纹孔，所述螺纹孔内转动连接有螺杆，所述螺杆顶端焊接有延伸杆，所述延伸杆顶端胶合有缓冲垫。本实用新型通过支撑柱、螺纹孔、螺杆和延伸杆的设置，
