[0014] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work belong to the scope of protection of the present invention.

[0015] Please refer to Figure 1-2 A quick-opening and closing mold lock for a concrete pipe well, which includes a bottom tray 1. A left outer mold 2 and a right outer mold 3 are slidably arranged on the bottom tray 1, and one end of the left outer mold 2 is rotatably connected to the right outer mold 3;

[0016] An inner mold 4 is jointly carried on the upper ends of the left outer mold 2 and the right outer mold 3, and the inner mold 4 is fixed between the left outer mold 2 and the right outer mold 3 through an inclined iron 5;

[0017] Insertion plates are arranged on the upper walls of the left outer mold 2 and the right outer mold 3. Transverse slots are opened on the insertion plates, and slots matching the insertion plates are opened on the inner mold. When installing the inner mold, insert the insertion plates into the slots, and hammer the inclined iron 5 into the slots to fix the inner mold on the outer mold;

[0018] A plurality of fixed plates 13 are uniformly arranged on the left outer mold 2 from top to bottom. A rotating shaft 14 is rotatably penetrated through the plurality of fixed plates 13. A plurality of cam connecting rods 11 are arranged on the rotating shaft 14. Connecting rods 10 are rotatably connected to the cam connecting rods 11. A screw 9 is rotatably arranged on the connecting rod 10, and a pair of bolts 8 are spirally arranged on the screw 9;

[0019] As Figure 2 shown, rotate the rotating shaft 14 counterclockwise to make the cam connecting rod 11 rotate counterclockwise, thereby driving the connecting rod 10 and the screw 9 to move to the right, and further moving the locking plate 7 to the right, so as to separate the left outer mold 2 from the right outer mold 3;

[0020] A locking plate 7 is arranged on the right outer mold 3, and a groove for the screw 9 to pass through is opened on the locking plate 7;

[0021] Pass the screw 9 through the groove so that the bolts 8 are located at both ends of the locking plate 7. Rotate the bolts 8 to make the bolts 8 closely adhere to both sides of the locking plate 7 to fix the screw 9 and the locking plate 7;

[0022] Supporting wheel sets 6 are arranged at the bottom of the bottom tray 1 to facilitate the movement of the device;

[0023] A lever 12 is commonly installed at the upper end of the rotating shaft 14 to facilitate driving the rotation of the rotating shaft 14.

[0024] When the concrete pipe well product meets the demolding requirements, first remove the inclined iron 5 on the inner mold 4, lift the inner mold 4 out with a crane, move the lever 12, rotate the rotating shaft 14 to drive the cam link 11 to rotate, push the connecting rod 10 and the screw 9 to move, push open the locked left and right outer molds, and lift the product out with a crane to complete the disassembly;

[0025] According to the needs of the production process, it is necessary to clean the inner wall of the mold. At this time, remove the bolt 8 from the screw 9, take out the screw 9 from the locking plate 7, and open the left and right outer molds to facilitate the cleaning of the inner wall.
