Embodiment Construction
[0031] The solution of the present invention will be described below in conjunction with the accompanying drawings.
[0032] refer to Figure 1 to Figure 6 , shows a sand core assembly jig for boxless molding according to the present invention, which includes at least two sets of jig subassemblies. The fixture subassembly includes an assembly base plate 1 and an assembly cover plate 2, each of which includes a pair of square steel pipes arranged in parallel, and the pair of square steel pipes are spaced apart by a first distance and at the ends The upper and lower sides of the place are welded together by connecting steel plates, thereby defining a first gap between the pair of square steel pipes. The clip subassembly also includes four spacers 4 formed by welding a clip nut 5 at the center of a circular steel plate with a hole, the diameter of which is equal to or greater than that of the clip. The diameter of the threaded hole of clamping nut 5, so as not to interfere with...
