[0025] Example 1: Figure 1 and 2 As shown, a tenon-under-type mold for casting imitation wood-grain concrete piles includes a tenon-under-type mold, and the tenon-under-type mold includes a fixed side mold 1 and multiple groups of movable side molds 2. An inner frame 5 is arranged in the concrete casting inner cavity 9 formed by closing the fixed side mold 1 and the movable side mold 2. Tenons 7 and grooves 6 that can be plugged in are respectively arranged on both sides of the inner frame 5. The tenon 7 of the inner frame 5 is located at the lower end of the concrete casting inner cavity 9, and the lower ends of the fixed side mold 1 and the movable side mold 2 are both provided with bottom molds 3. Positioning grooves 4 formed by closing together are arranged on the bottom molds 3 at the lower ends of the fixed side mold 1 and the movable side mold 2. The tenon 7 is fixedly clamped in the positioning groove 4, and the groove 6 on the inner frame 5 extends to the outer side of the upper end of the concrete casting inner cavity 9.

[0026] By placing the tenon 7 downward, the groove 6 structure that matches it is extended to the outside of the upper end of the casting cavity 9, thereby avoiding the contamination of the inside of the groove by concrete mud during casting, thereby improving the accuracy of the fitting and insertion of the tenon 7 and the groove 6 after molding.

[0027] At the same time, the fixed side mold 1 and the movable side mold 2 are coordinated and closed to form a casting inner cavity 9. During the closing process, the positioning slot 4 is closed, thereby simultaneously achieving the purpose of clamping the tenon 7 without applying additional force, thereby realizing integrated drive, and while clamping the tenon 7, the inner frame 5 is fixedly installed, thereby improving the installation stability of the inner frame 5 during casting, thereby improving the quality and precision of the mold after casting.

[0028] Embodiment 2: On the basis of Embodiment 1, in order to prevent the mud in the casting inner cavity 9 from leaking along the positioning slot 4, a clamping block 13 is symmetrically arranged at the upper end of the positioning slot 4, and the clamping block 13 is longitudinally extended and installed along the arc-shaped inner contour of the concrete casting inner cavity 9. The clamping blocks 13 are respectively arranged at the lower ends of the fixed side mold 1 and the movable side mold 2, and gaps are left between adjacent clamping blocks 13. Side panels connected to the tenons 7 are provided on the inner frame 5, and the side panels extend through the gaps, and the clamping blocks 13 are pressed onto the side panels of the inner frame 5 connected to the tenons 7. The ends of the clamping blocks 13 close to the upper side panels of the inner frame 5 are set as planes, and the planes on the clamping blocks 13 are pressed tightly against the outer walls of the side panels on both sides.

[0029] By setting the clamping block 13, the side plate connecting the tenon 7 is tightened and clamped, while keeping the inner wall of the casting cavity 9 intact. By setting the clamping block 13 as a plane, the contact area is increased and the sealing of the lower end of the casting cavity 9 is improved.

[0030] Embodiment 3: Based on Embodiment 2, slide rails are provided on both sides of the fixed side mold 1, the lower end of the movable side mold 2 slides laterally along the slide rails, a through hole is provided in the middle of the inner frame 5, and end plates for blocking the through hole and the concrete pouring inner cavity 9 are provided at both ends of the tenon-under-type mold, and the groove 6 on the inner frame 5 extends to the outer side of the upper end of the concrete pouring inner cavity 9

[0031] The position of the movable side mold 2 is limited by setting the slide rail to ensure the accuracy of mold closing, and the purpose of sealing the front and rear ends of the casting cavity 9 is achieved by setting the end plates to form a closed casting cavity 9.

[0032] Example 4: Figure 3 , 4 As shown, on the basis of Example 2, in order to adapt to different structures of the inner frame 5, a bottom limit block 8 located at the lower end of the positioning slot 4 is provided on the lower end bottom mold 3 of the fixed side mold 1, and the bottom limit block 8 is used to support the lower end outer wall of the tenon 7, and a positioning member for fixing the position of the groove 6 at the upper end of the inner frame 5 is provided on the fixed side mold 1, and the positioning member includes a cross beam 11 fixed on the fixed side mold 1, and a groove fixing side pin 12 located at the upper end of the groove 6 is vertically arranged on the cross beam 11, and a positioning disc 10 pressed on the inner wall of the groove 6 is provided at the lower end of the groove fixing side pin 12.

Therefore, when the tenons 7 and grooves 6 are not an integral structure, in order to fix the positions of the tenons 7 and grooves 6, a bottom limit block 8 is provided to support the lower tenons 7, and the upper grooves 6 are limited in position by providing a positioning device, thereby ensuring the position accuracy of the tenons 7 and grooves 6 in the casting inner cavity 9 and improving the accuracy after casting.

[0034] The outline size of the cavity surrounded by the bottom limiting block 8 , the clamping block 13 and the positioning slot 4 is larger than the cross-sectional size of the tenon 7 .
