When the concrete injected into the casting cavity is cured and formed, a structure as shown in fig. 11 is formed, in which the formed concrete layer 140 is located between the lower mold 100, the filling mold 200, and the upper mold 300.

After the concrete is formed, the upper mold 300 is taken down (as shown in fig. 12), then the two filling plates 700 of the filling mold 200 are pulled apart, after the two filling plates are far away from each other and close to the hook heads of the hooked steel bars 160, the filling plates 700 are taken out along the length direction of the pouring cavity to form the structure shown in fig. 12, at this time, the lower layer hooked steel bars 160 of the formed inner page product are positioned above the lower mold 100 (as shown in fig. 13), and the product is moved upwards by a crane or other lifting equipment, so that the separation of the product and the lower mold 100 can be realized. Therefore, after the structure is adopted, concrete can be prevented from flowing to the outside from the pouring cavity for forming in the pouring process, and then after the concrete is solidified and formed into a product, the upper die 300, the filling die 200 and the product can be conveniently taken out in sequence, so that the demoulding and the product taking-out operation are facilitated.

As shown in fig. 2, two opposite sides of the two filling plates 700, that is, one side of the two filling plates 700 adjacent to the casting cavity, are provided with a protruding strip 701, the protruding strip 701 extends in a direction parallel to the length direction of the casting cavity and is located between the first through hole 400 and the second through hole 500, and the protruding strip 701 is located between two ends of the corresponding filling plate 700.

After adopting above-mentioned structure, the infill panel 700 for go up mould 300, filling mould 200 and lower mould 100 and enclose and close the pouring chamber that forms, its length direction's both sides are interior concavity, so, at pouring intracavity pouring concrete, treat the concrete curing shaping back, the circumference outer fringe both sides of the concrete layer 140 that forms, integrated into one piece is fluted 141, makes things convenient for the connection between the sandwich core wallboard.

In order to facilitate the quick detachable connection among the lower die 100, the filling die 200 and the upper die 300, the three are connected in a plug-in fit manner; specifically, as shown in fig. 5 and 6, the lower mold 100 is provided with the lower plug bush 101 located at the four corners of the casting cavity, the two ends of the two filling plates 700 are both provided with the positioning plug bush 702, the upper mold 300 is provided with the upper plug bush 301 located at the four corners of the casting cavity, the lower plug bush 101, the positioning plug bush 702 and the upper plug bush 301 correspond to each other and are both arranged outside the casting cavity and extend along the vertical direction, and the lower plug bush 101, the upper plug bush 301 and the positioning plug bush 702 are in plug-in fit through the plug pin 180.

When the lower mold 100, the filling plate 700 and the upper mold 300 are sequentially arranged from bottom to top, the axes of the holes of the lower insert 101, the positioning insert 702 and the upper insert 301 are the same, and at this time, the plug pin 180 is inserted into the three, so that the lower mold 100, the filling plate 700 and the upper mold 300 can be connected, and the horizontal position deviation of the lower mold 100, the filling plate 700 and the upper mold 300 can be prevented.

The specific structure of the lower mold 100, the filling plate 700 and the upper mold 300 is as shown in fig. 3-7, the lower mold 100 includes a horizontal bottom plate 170, a rectangular bottom frame 800 is fixed on the bottom plate 170, first lower notches 802 extending along the length direction of the bottom frame 800 are respectively arranged on both sides of the top surface of the bottom frame 800, a plurality of first lower notches 802 are distributed on the inner bottom wall of the lower notches 801 along the length direction thereof, and a plurality of third lower notches 803 are respectively arranged at both ends of the top surface of the bottom frame 800; the bottom parts of the two filling plates 700 are provided with a plurality of first upper notches 703 corresponding to the first lower notches 802 one by one, and the top parts are provided with second lower notches 704 corresponding to the first upper notches 703 one by one; both sides of the bottom surface of the top frame 900 are provided with upper notches 901 extending along the length direction thereof, the inner bottom wall of the upper notches 901 is provided with a plurality of second upper notches 902 distributed along the length direction thereof, the second upper notches 902 correspond to the second lower notches 704 one by one, and both ends of the bottom surface of the top frame 900 are provided with third upper notches 903 corresponding to the plurality of third lower notches 803 one by one.

After the lower die 100, the filling plate 700 and the upper die 300 are sequentially connected from bottom to top, a lower notch 801 of the bottom frame 800 and an upper notch 901 of the top frame 900 are enclosed to form a notch, and the filling plate 700 is filled in the notch, namely the circumferential outer edge of the filling plate 700 is in sealing fit with the circumferential inner wall of the notch, so that concrete is prevented from flowing out of a pouring cavity when the concrete is poured; when the lower die 100, the filling plate 700 and the upper die 300 are connected, the first upper notch 703 and the first lower notch 802 are combined to form a first through hole 400, the second upper notch 902 and the second lower notch 704 are combined to form a second through hole 500, the third upper notch 903 and the third lower notch 803 are combined to form a third through hole 600, the first through hole 400 and the second through hole 500 are respectively in sealing fit with the hooked steel bars 160 on the upper side and the lower side, and the third through hole 600 is in sealing fit with the straight steel bars 150, so that after concrete is injected into the casting cavity, the cured and molded concrete can be molded into a concrete layer 140 structure as shown in fig. 1.

The upper mold 300 further includes a spill prevention member 110 disposed inside the top surface of the top frame 900, and the spill prevention member 110 is a frame structure. Make things convenient for the operation workman to observe the concrete placement material in the pouring cavity through anti-overflow piece 110, after the concrete of pouring and the anti-overflow piece 110 bottom surface contact, stop to pour into the concrete, avoid pouring into the concrete too much, and lead to the concrete to spill over from the pouring cavity top, cause the waste of production material.
