Embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.
Reference picture 1-2, a kind of synchronous demolding structure of core, including upper mould 6 and lower mould 7, the top welding of the upper mould 6
There is hydraulic lifting arm, the inner vertical of the upper mould 6 offers through hole, and the inwall of the lower mould 7, which is provided with perforate, and perforate, to be set
There is fuse 10, the outer wall of the lower mould 7 is socketed with cavity plate 9, and the outer wall top of the cavity plate 9 is welded with horizontally disposed flange 8,
The bottom both sides of the cavity plate 9 are respectively connected with contiguous block 5 by fastening bolt, and two contiguous blocks 5 bottom be welded with it is same
Individual U-shaped support 11, the bottom middle part of the U-shaped support 11 is offered by screwed hole, the bottom welding of the U-shaped support 11
Have a nut 12, and nut 12 screw it is identical with screwed hole size be adapted, the screw internal thread of the nut 12 is connected with silk
