[0053] The utility model provides a vertical interlocking block double-layer mold, such as Figures 4 to 11 As shown, the vertical interlocking block double-layer mold includes an integrated outer mold 2, an inner mold component 3 and a hole forming component 4.

[0054] The integrated outer mold 2 includes a bottom plate 21 and four outer mold side plates 22 , and the bottom plate 21 and the four outer mold side plates 22 form an inner cavity with an opening facing upward.

[0055] The inner mold assembly 3 includes a first inner mold plate 31 and a second inner mold plate 32 that are oppositely disposed, and two inner mold side plates 33 that are oppositely disposed. A convex surface 311 is formed on the first inner mold plate 31 , and a concave surface 321 is formed on the second inner mold plate 32 .

[0056] The first inner formwork 31 and the second inner formwork 32 are respectively attached to the inner sides of two opposite outer formwork side plates 22, and the two inner formwork side plates 33 are respectively attached to the inner sides of the other two opposite outer formwork side plates 22. The two side edges of the inner formwork side plates 33 are respectively attached to the edge of the first inner formwork 31 and the edge of the second inner formwork 32.

The first inner mold 31, the second inner mold 32, and the two inner mold side plates 33 are not connected, and are easy to assemble, and the vertical interlocking block 1 is easy to detach from the inner mold assembly 3, which is convenient to use.

[0060] To further reduce the demoulding difficulty of the vertical interlocking block 1, the four outer mold side plates 22 are tilted outward from bottom to top to form a flared structure. The first inner mold plate 31, the second inner mold plate 32 and the two inner mold side plates 33 are tilted outward from bottom to top to form a flared structure.

[0061] In detail, Figure 6 and Figure 7 As shown in FIG. 1 , the top edges of the four outer mold side panels 22 respectively form outer mold flanges 23 extending outward. Figure 8 As shown, the top edges of the first inner template 31 and the second inner template 32 respectively form inner mold flanges 34. Figure 8 As shown, the inner mold flange 34 overlaps the corresponding outer mold flange 23. The outer mold flange 23 supports the inner mold flange 34, and can play a positioning role for the first inner mold plate 31 and the second inner mold plate 32.

[0062] Furthermore, the inner mold flanges 34 of the first inner mold plate 31 and the second inner mold plate 32 are pressed on the top edges of the two inner mold side plates 33. Specifically, the inner mold flanges 34 of the first inner mold plate 31 and the inner mold flanges 34 of the second inner mold plate 32 extend to the left and right sides respectively, press on the top edges of the left and right inner mold side plates 33, and limit the positions of the two inner mold side plates 33.
