[0089] like Figure 8 , Fig.10 As shown, the outermost movable partition wall is connected to the adjacent movable partition wall via a first connecting plate 802;

[0090] Adjacent movable partition walls located inside are connected via a second connecting plate 803;

[0091] The middle wall 2 is connected to the adjacent movable partition wall via a third connecting plate 804;

[0092] The first connecting plate 802, the second connecting plate 803, and the third connecting plate 804 are respectively connected to the square hole wall panel forming mold 4 located at the upper part. Specifically, the first connecting plate 802, the second connecting plate 803, and the third connecting plate 804 are respectively connected to the lower forming side mold 402 located at the upper part.

[0096] The bottom hinge axis of the movable partition wall 3 located inside is hingedly connected to the corresponding aligned strip holes;

[0097] The inner end of the third connecting plate 804 is connected to the middle wall 2 .

[0098] The mold opening process is explained by taking the example of the middle wall 2 with three movable partition walls 3 on each side. Fig.11 As shown (taking the mold opening on one side of the middle wall 2 as an example, the other side is the same).

[0099] First, let me explain the positional relationship between the movable partition wall 3 and each strip hole 805 during the molding process (taking the left side of the middle wall 2 as an example, the right side is symmetrical to the left side): the outermost movable partition wall 3 is located at the right end of the strip hole at the outer end of the first connecting plate 802; the second movable partition wall is located at the left end of the strip hole at the inner end of the first connecting plate 802 and the right end of the strip hole at the outer end of the second connecting plate 803; the third movable partition wall is located at the left end of the strip hole at the inner end of the second connecting plate 803 and the right end of the strip hole at the outer end of the third connecting plate 804.

[0100] The mold opening process is as follows:

[0101] 1. The mold opening cylinder 801 is started to move the outermost movable partition wall 3 along the slider 101 on the base 1 from the right end of the outer end strip hole of the first connecting plate 802 to the left end, so as to separate the outermost movable partition wall 3 from the left end of the corresponding square hole wallboard forming mold 4. Fig.11 (a)

[0102] 2. The piston rod of the mold opening cylinder 801 continues to extend, driving the outermost movable partition wall 3 and the first connecting plate 802 to move to the left along the slider 101 on the base 1. During the movement of the first connecting plate 802, the square hole wall panel forming mold 4 on the upper part of the first connecting plate 802 moves to the left, realizing the separation of the right end of the square hole wall panel forming mold 4;

[0103] At the same time, during this process, the hinge axis at the bottom of the second movable partition wall moves relatively in the inner strip hole of the first connecting plate 802. At this time, the second movable partition wall is located at the right end of the inner strip hole of the first connecting plate 802 and the right end of the outer strip hole of the second connecting plate 803. Fig.11 (b)

[0104] 3. The piston rod of the mold opening cylinder 801 continues to extend, driving the outermost movable partition wall 3, the first connecting plate 802, the square hole wall panel forming mold 4 on the first connecting plate 802, and the second movable partition wall to move to the left along the slider 101 on the base 1. In this process, the second movable partition wall moves from the right end of the outer end strip hole of the second connecting plate 803 to the left end along the slider 101 on the base 1, so as to separate the second movable partition wall 3 from the left end of the corresponding square hole wall panel forming mold 4. Fig.11 (c)

[0105] 4. The piston rod of the mold opening cylinder 801 continues to extend, driving the outermost movable partition wall 3, the first connecting plate 802, the square hole wall panel forming mold 4 on the first connecting plate 802, the second movable partition wall 3, and the second connecting plate 803 to move to the left along the slider 101 on the base 1;

[0106] During the movement of the second connecting plate 803, the square hole wall panel forming mold 4 on the upper part of the second connecting plate 803 moves leftward accordingly, so as to separate the right end of the square hole wall panel forming mold 4. Meanwhile, during this process, the hinge shaft at the bottom of the third movable partition wall moves relatively in the inner strip hole of the second connecting plate 803. At this time, the third movable partition wall is located at the right end of the inner strip hole of the second connecting plate 803 and the right end of the outer strip hole of the third connecting plate 804. Fig.11 (d)

[0107] 5. The piston rod of the mold opening cylinder 801 continues to extend, driving the outermost movable partition wall 3, the first connecting plate 802, the square hole wall panel forming mold 4 on the first connecting plate 802, the second movable partition wall, the second connecting plate 803, the square hole wall panel forming mold 4 on the second connecting plate 803, and the third movable partition wall to move to the left along the slider 101 on the base 1. In this process, the third movable partition wall moves from the right end of the outer end strip hole of the third connecting plate 804 to the left end along the slider 101 on the base 1, so as to separate the third movable partition wall 3 from the left end of the corresponding square hole wall panel forming mold 4, as shown in FIG. Fig.11 (e) as shown.

[0108] Therefore, in the present application, the mold opening assembly 8 can realize the separation and mold closing of each movable partition wall 3 and the corresponding square hole wallboard forming mold 4 in sequence through the arrangement of the mold opening cylinder 801 and each connecting plate, and the operation is simple. The mold closing process is opposite to the above-mentioned mold opening process.

[0116] After the equipment is installed, the molding fluid is injected into the sealed molding cavity 5 through the grouting port at the bottom of the upper molding side mold 401; then wait for molding. After molding is completed, first remove the sealing door 7, then unscrew the locking nut 901 on the locking rod 9, and then start the mold opening cylinder 801 to separate the movable partition walls 3 on both sides of the middle wall 2 from the corresponding square hole wallboard molding mold 4 in turn; then remove each upper molding side mold 401 and the blocking end molds 403 at both ends, and demold the molded square hole wallboard by lifting or dragging. Among them, the structure of the square hole wallboard finally formed by the device of the present application is as follows: Fig.12 shown.

[0117] Although the above describes the specific implementation mode of the present invention in conjunction with the accompanying drawings, it is not a limitation of the present invention.
