<p>A positing structure for melt cylinders comprises: a melt cylinder (2) having step part (21), a supporting stage (3) of the melt cylinder (2) and a positing foundation (4) of the melt cylinder (2) respectively having step arc grooves (31, 41) corresponding with the bottom and the top of said melt cylinder's step part (21), and herein the step arc grooves (31, 41) having a radial length corresponding with that of the melt cylinder (2). In the way, it is accomplished that horizontal assembling and positing are accurate to prevent inclining problems resulted by a too long cylinder.</p> |
