It is worth noting that the sleeve has two internal threads in opposite directions. The thread on the surface of the screw is opposite to the internal thread on its corresponding side. Therefore, by rotating the sleeve clockwise or counterclockwise, the length of the screw extending into or out of the sleeve can be adjusted to accommodate the rotation angle of the end mold 4.

[0034] like Figure 2As shown, the front and rear side walls and the left and right side walls near the top of the bottom mold 101 are respectively provided with a plurality of first connecting ears 108 and second connecting ears 109 at equal intervals. In order to realize the sliding opening of the side mold 3, at least three sets of opening and closing mechanisms are provided at equal intervals along the length direction of the lower part of the front and rear side walls of the bottom mold 101; specifically, each set of opening and closing mechanisms includes a track base 104 extending outward along the width direction of the bottom mold 101; a guide rail 106 is provided on the top of the track base 104 along its length direction, and a limiting baffle 1061 is provided at the end of the guide rail 106 away from the bottom mold 101 to prevent the side mold 3 from derailing; a connecting member 105 is provided on the top of the guide rail 106 through a slider 107. The top of the connecting member 105 is fixed to the bottom of the side mold 3, thereby realizing the sliding connection between the side mold 3 and the bottom mold 101.

[0035] like Figure 4 As shown, the bottom edge of the side mold 3 is provided with several fasteners 301 at equal intervals. The side mold 3 is fixed to the first connecting lugs 108 on the front and rear side walls of the bottom mold 101 by the fasteners 301. Several through holes 302 are provided at equal intervals on the left and right sides near the edges of the side mold 3. The end mold 4 is provided with several bolt holes 404 corresponding to the positions of the through holes 302. The end mold 4 is fixed to the side mold 3 by fastening bolts passing through the through holes 302 and the bolt holes 404 in sequence.

[0036] like Figure 3 As shown, the core mold 2 includes two mirror-symmetrical unit core molds, which are connected by a core mold connector 202; each unit core mold has a plurality of locking members 201 evenly spaced on the front and rear sides of the top wall and the front and rear sides of the side wall away from the other unit core mold; the unit core mold is locked to the side mold 3 by the plurality of locking members 201.

[0037] like Figure 5-6 As shown, the end mold 4 is provided with a connecting component at the position of each second connecting ear 109 on the left and right sides of the bottom mold 101; each connecting component includes two shaft seats 401 arranged in a mirror symmetrical manner; the two shaft seats 401 of each connecting component are respectively located on both sides of the corresponding second connecting ear 109, and a gasket 402 is provided on the side of the two shaft seats 401 away from the end mold 4, and the gasket 402 is provided with an insertion hole; the shaft seat 401 is provided with a shaft hole at the position of the ear hole of the second connecting ear 109; the end mold 4 is also provided with a mounting hole at the position of the insertion hole of the gasket 402.

[0038] To counteract the expansion force generated by the concrete components during curing, several fine-tuning tie rods 6 are installed at equal intervals between the tops of the two side molds 3.

[0039] To reduce the deviation of the initial embedded position and improve the positioning accuracy of the mold, several embedded part alignment devices 7 are also provided corresponding to the positions of several embedded parts on the side mold 3. Specifically, as shown... Figure 7-8 As shown, the pre-embedded part alignment device 7 includes a base 701, a fixing rod 702, and a handhole box 704. The base 701 is fixed to the top of the side mold 3; the fixing rod 702 is horizontally positioned on the top of the base 701 and extends towards the molding mold cavity; an alignment plate 703 is provided on the bottom of the fixing rod 702 near the base 701. During installation, the alignment plate 703 is pressed against the inner edge of the top wall of the side mold 3 to achieve positioning and alignment. Preferably, the handhole box 704 is positioned below the fixing rod 702 on the side away from the base 701 via a connecting rod, and the handhole box 704 has a slot 7041 with the same inclination angle as the side mold pre-embedded part. When installing the side mold pre-embedded part, one end is fixed to the pre-embedded part mounting hole on the side mold 3, and the other end is inserted into the slot 7041 of the handhole box 704 to ensure the accuracy of the side mold pre-embedded part installation position.

[0040] More preferably, a number of horizontal vibrators are evenly spaced along the length of the bottom mold 101. The horizontal vibrators are fixed to the top wall of the bottom mold by a vibrating beam. During installation, it is ensured that the horizontal vibration direction is consistent with the self-weight direction of the concrete, which can effectively reduce energy loss, shorten the vibration time required to achieve the same density, and effectively reduce segregation.

[0041] More preferably, a walkway is provided on the top of both side molds 3 along their length. In order to ensure the load-bearing performance of the walkway, several ribs 303 are also provided at equal intervals on the side molds 3 corresponding to the positions below the walkway. A safety railing 5 is also installed on the edge of the walkway.

[0042] The specific working principle of the molding die provided by this utility model is as follows:

[0043] During mold closing, firstly, one side mold 3 is slid to the top position of the bottom mold 101, and the first connecting lug 108 and fastener 301 are fixed with fastening bolts; then, the core mold 2 is placed and the core mold 2 is locked to the side mold 3 using locking member 201; next, the other side mold 3 is slid to the top of the bottom mold 101 to be fixed to the bottom mold 101, and the core mold 2 is locked to the other side mold 3; after that, the end mold 4 is installed, and the second end mold 4 is installed on the bottom mold 101. The ear hole of the connecting ear 109 and the shaft hole of the bearing seat 401 are connected by the rotating shaft 403. Then, fastening bolts are used to pass through the insertion hole of the washer 401 and the mounting hole of the end mold 4 in sequence, thereby realizing the mold closing and fixing of the lower part of the end mold 4 and the bottom mold 101. Then, the bolt hole 404 on the side of the end mold 4 and the through hole 302 of the side mold 3 are fixed by fastening bolts. Finally, the length of the adjustable support rod 103 is adjusted so that it has a supporting effect on the end mold 4, thereby completing the entire mold closing process between the bottom mold 101, the core mold 2, the side mold 3 and the end mold 4.

[0044] When opening the mold, firstly, open the locking pieces 201 that are fixed to the side mold 3 on both sides of the core mold 2, and take the core mold 2 out from the side mold 3; then, remove the first connecting ear 108, the fastener 301, and the fastening bolts between the side mold 3 and the end mold 4, and slide the side mold 3 away from the bottom mold 101 through the opening and closing mechanism to complete the removal between the side mold 3 and the bottom mold 101; finally, remove the fastening bolts between the gasket 401 and the mounting hole and adjust the length of the adjustable support rod 103 to shorten it, and then open the end mold 4 through the rotating shaft 403.

[0045] The side molds and end molds of this invention are connected to the bottom mold by sliding or hinged connections, and the core mold is connected to the side mold by snap-fit ​​connections. This makes operation simple and convenient for mold closing and demolding, effectively improving production efficiency. The addition of a pre-embedded part alignment device effectively reduces the deviation of the initial position of the pre-embedded parts and improves positioning accuracy. The width between the two side molds is finely adjusted by a fine-tuning tie rod to counteract the expansion force of the concrete during curing. In addition, the molded components made using the mold provided by this invention only require manual finishing of the top surface of the component. Since the top surface is not used as the splicing surface of the component, the surface quality requirements are not high. This effectively solves the problem of poor surface forming quality and inconvenient mold opening in traditional vertical structures, which easily leads to edge and corner damage during demolding.
