Abstract:
An elastic mold for fabricating a concrete cylinder, comprising a first elastic connecting plate (1) and a second elastic connecting plate (2). Two ends of the first elastic connecting plate (1) extend toward a same side to form a first convex plate (5) and a second convex plate (7). A first groove (4) is formed in an outer end surface of the first convex plate (5). Two ends of the second elastic connecting plate (2) extend toward a same side to form a third convex plate (9) and a fourth convex plate (11). A first bump (10) is arranged on an outer end surface of the third convex plate (9). The first groove (4) and the first bump (10) are plug-connected, and the second convex plate (7) and the fourth convex plate (11) are fixedly connected.
