Using precast concrete components to construct prefabricated buildings can improve the degree of factory and mechanized construction, save on-site labor, and shorten the construction period.

[0003] Prefabricated concrete slab components are called wall panels. The use of prefabricated wall panels can reduce on-site wet work, save on-site labor, and shorten the construction period.

[0004] In order to meet the needs, wall panels come in many sizes and styles, so the molds used to manufacture wall panels also need to have many styles. On the one hand, fixed molds have the problem of difficulty in demoulding. On the other hand, when manufacturing wall panels of multiple sizes and styles, multiple corresponding molds are required, and the mold cost is also high. Utility Model Content

[0005] The technical problem to be solved by the utility model is to provide a prefabricated wallboard production mold, which adopts a movable mold and is easy to demould.

[0006] The technical solution adopted in this utility model is:

[0014] Furthermore, a support rod with adjustable length is provided between the bottom of the adjustment plate and the inner side wall of the long template.

[0015] The positive effects of this utility model are:

[0016] The two long templates of the utility model adopt a movable design, and their positions are adjusted by using a spacing adjustment device. When demoulding is required, the two long templates are moved outward to quickly achieve demoulding.

[0020] Example 1

[0021] As attached Figure 1 As shown, this embodiment provides a mold for manufacturing prefabricated wall panels, including a long template 1, a right template 2, a left template 5, and a spacing adjustment device. The long templates 1 are two parallel templates, and the left template 5 and the right template 2 are located between the two long templates 1 and at both ends of the long templates 1. Connecting columns 3 are provided on both the left template 5 and the right template 2. Connecting holes for matching with the connecting columns 3 are provided at both ends of the long template 1. One connecting hole is a circular hole and the other is an oblong hole. This can avoid over-positioning, relatively low machining accuracy requirements during the mold processing, and facilitates smooth matching of the connecting columns 3 with the corresponding connecting holes during the movement of the long template 1. The position of the two long templates 1 is adjusted by the spacing adjustment device. When demolding is required, the two long templates 1 can be moved outward, which helps to achieve wall panel demolding.

[0022] Preferably, the connecting post 3 on the right template 2 is cylindrical and fits in the oblong hole on the long template 1. The connecting post 3 on the left template 5 is conical and fits in the circular hole on the long template 1. This can further facilitate smooth fit between the long template 1 and the left and right templates.

[0023] A pushing device 10 is provided on the outside of the right template 2. The pushing device 10 adopts an oil cylinder or an electric push rod. When demoulding, the right template 2 moves outward first, and then the two long templates 1 move outward. During processing, the right template 2 moves inward first so that its connecting column is close to the inner end of the oblong hole on the long template 1. Then the two long templates 1 move again to achieve three-sided demoulding.

[0024] The spacing adjustment device includes a motor 7, a lead screw 8, and a lead screw nut. Connecting plates 9 are provided at the left and right ends of the long template 1. The lead screw nut is fixed to the connecting plate 9. The motor 7 is located between the two opposing connecting plates 9. The lead screw 8 is connected to the motor 7 in a transmission manner. The threads at both ends of the lead screw 8 are in opposite directions and respectively engage with the two corresponding lead screw nuts through threads. When the motor 7 drives the lead screw 8 to rotate, it drives the two long templates 1 to move inward or outward at the same time. The motor 7 uses a stepper motor. After the long template 1 moves inward into position, the motor 7 still maintains the force, making the long template 1 more closely contacted with the left and right templates.

[0025] Example 2

[0026] This embodiment is improved on the basis of embodiment 1. Figure 2 、 3 As shown, an adjustment plate 11 is installed on the inner side of one of the long templates 1, and the two ends of the adjustment plate 11 are respectively fitted with the left template 5 and the right template 2. The width of the prefabricated wall panel is adjusted by adjusting the plate 11, so that the production of wall panels of different sizes can be achieved.

[0027] Preferably, a positioning device for positioning the adjustment plate 11 is provided on the long template 1. The positioning device includes a mounting seat 13 provided at the outer end of the top of the long template 1, a pressure plate 12 connected to the mounting seat 13 at one end by a rotating shaft, and a limiting nut 14 installed on the pressure plate 12 and the long template 1. The other end of the pressure plate 12 presses the top position of the adjustment plate 11 to position the upper end position of the adjustment plate 11. A through hole is provided on the pressure plate 12, and a threaded hole corresponding to the position of the through hole is provided on the top surface of the long template 1. The limiting nut 14 passes through the through hole from above and is threadedly connected to the threaded hole to provide downward pressure on the pressure plate 12 to ensure positioning accuracy. After the right template 2 moves inward into position, the right end of the adjustment plate 11 fits against the right template 2.

[0028] To further improve positioning accuracy, an adjustable-length support rod 15 is installed between the bottom of the adjustment plate 11 and the inner sidewall of the corresponding long template 1. This is used to position the bottom of the adjustment plate 11 and prevent it from shifting during production. The position of the adjustment plate 11 can be adjusted according to production and processing requirements, allowing the production of wall panels of various sizes.

[0029] The right template 2 and the two long templates 1 of the utility model can be adjusted in position, can be demoulded on three sides, can achieve rapid demoulding, and improve demoulding efficiency. At the same time, the design of the adjustment plate 11 can be used to produce wall panels of different widths and sizes to meet more production and processing requirements.
