DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-5 The utility model provides a technical solution: a mold for quick demoulding of concrete blocks, comprising: a bottom plate 1, a vertical plate 2, a motor 3, a first template 4, a second template 5, a clamping claw 6, a first installation box 7, a chuck body 8, a first transmission wheel 9, a second transmission wheel 10, a double-headed screw 11, a slider 12, a connecting rod 13, a sealing plate 14, a second installation box 15, a connecting shaft 16, a residual gear 17, a striking block 18 and a spring 19.

[0029] When using the mold for quick demoulding of concrete blocks, first Figure 1 , Figure 2 and Figure 3 As shown, the vertical plate 2 is fixedly installed on the upper end of the base plate 1, the first template 4 is fixedly connected to the upper end of the vertical plate 2, the lower part of the second template 5 is rotatably connected to the first template 4, the outer side of the first template 4 is provided with grooves, the cross-section of the second template 5 is trapezoidal, and the lower end of the second template 5 is rotatably connected to the claw 6, the lower end of the first installation box 7 is fixedly connected to the middle of the upper end of the base plate 1, the chuck body 8 is rotatably connected to the inside of the first installation box 7, and the upper end of the chuck body 8 is provided with an Archimedean spiral groove, and the chuck body 8 is meshed with the claw 6 for transmission, the upper part of the claw 6 is slidably connected to the inner side of the first installation box 7, and the claw 6 is symmetrically arranged along the central axis of the first installation box 7, the middle lower end of the chuck body 8 is fixedly installed with a first transmission wheel 9, the first transmission wheel 9 is rotatably connected to the inside of the first installation box 7, and the first transmission wheel 9 is meshed with the second transmission wheel 10 for transmission, and the second transmission wheel 10 is rotatably connected to the inner side of the first installation box 7;

[0030] The double-headed screw 11 is rotatably connected to the inside of the bottom plate 1, and the slider 12 is rotatably connected to the double-headed screw 11. A connecting rod 13 is fixed to the upper end of the slider 12, and the inner side of the connecting rod 13 is fixedly connected to the sealing plate 14, and the movement direction of the slider 12 is opposite. The lower part of the connecting rod 13 is slidably connected to the inner side of the upper end of the bottom plate 1. The bottom plate 1 is placed on a flat table surface, and concrete is injected from the upper end into the space formed by the first template 4 and the second template 5. The double-headed screw 11 is rotated to make the slider 12 rotate outside the double-headed screw 11. The slider 12 drives the connecting rod 13 to move in the direction of each other, so that the sealing plate 14 is tightly stuck at the connection between the second template 5 and the second template 5, further connecting the first template 4 and the second template 5 tightly, and waiting for sufficient time for the concrete to solidify before demoulding;

[0031] Rotating the double-headed screw 11 in the opposite direction causes the connecting rod 13 to drive the sealing plate 14 to separate from the second template 5, and rotating the second transmission wheel 10 causes the first transmission wheel 9 to rotate inside the first installation box 7. The chuck body 8 is driven by the first transmission wheel 9 to start rotating, and the claw 6 engages with the groove at the upper end of the chuck body 8 for transmission, controlling the claw 6 to move toward the center of the chuck body 8. The first installation box 7 limits the position of the claw 6, and the second template 5 is pulled by the claw 6 to start rotating along the hinge point with the first template 4. The second template 5 expands outward and separates from the concrete block, making it convenient to take out the complete concrete.

[0032] like Figure 1 , Figure 4 and Figure 5 As shown, the motor 3 is fixedly installed inside the second installation box 15, the upper and lower ends of the second installation box 15 are fixedly connected to the first template 4 and the first installation box 7 respectively, the left end of the connecting shaft 16 is fixedly connected to the output end of the motor 3, the residual gear 17 is fixedly sleeved on the outside of the connecting shaft 16, the striking block 18 is arranged on the rear side of the residual gear 17, the residual gear 17 is meshed with the striking block 18 for transmission, and the striking block 18 is slidably connected to a groove provided at the upper end of the second installation box 15, the connecting shaft 16 is rotatably connected to the inside of the second installation box 15, and the residual gear 17 is symmetrically arranged at two locations along the central axis of the connecting shaft 16, a spring 19 is installed at the lower end of the striking block 18, and the spring 19 is fixedly connected to the second installation box 15;

[0033] After the concrete pouring is completed, the motor 3 is turned on so that the connecting shaft 16 drives the residual gear 17 to start rotating, and the serrations on the residual gear 17 begin to intermittently mesh with the striking block 18. When the residual gear 17 meshes with the striking block 18, the striking block 18 is driven to move upward, and the spring 19 undergoes elastic deformation. When the residual gear 17 loses meshing with the striking block 18, the position of the striking block 18 is restored under the elastic action of the spring 19, so that the striking block 18 regularly impacts the lower end of the first template 4, thereby shaking out the bubbles in the concrete, ensuring the density of the concrete block, and improving the quality standard of the finished product.
