For example, both ends of the supporting member 105 in fig. 1 are folded to the left side, and the folding point 107 is shifted to the right side by a predetermined distance with reference to the predetermined connection line 106.
In an alternative embodiment of this embodiment, when the supporting member 105 is in the straightened state, the distance between the two end points of the supporting member 105 is a predetermined length, and the predetermined connecting line 106 is a central axis of the supporting member 105.
In this embodiment, the folding bar is used to support the template 102 when straightened for better stability. At this time, a connection line (i.e., the preset connection line 106) between the connection point of the supporting member 105 and the mold plate 102 and the connection point of the supporting member 105 and the supporting frame 103 penetrates through the whole supporting member 105, and the preset connection line 106 is a central axis of the supporting member 105, so that the stress of the supporting member 105 is more balanced, and the supporting stability is further enhanced.
In an optional solution of this embodiment, the supporting member 105 further includes a locking member, and when the distance between the two end points of the supporting member 105 is a predetermined length, the locking member is used to lock the supporting member 105, so that the supporting member 105 is locked in the supporting state. Specifically, the locking member may be a pin or other structure that extends through the upper and lower struts 108, 109, etc.
In an alternative of this embodiment, two ends of the supporting member 105 are detachably connected to the mold plate 102 and the supporting frame 103, respectively. When the section space of the tunnel is small, the supporting piece 105 can be detached, the oil cylinder is only used for being directly connected with the template 102, the occupied space is small, and the template 102 can be driven to rotate by the small expansion amount of the oil cylinder so as to fold the template 102.
