Rapid forming mold for high-strength composite cement pipe

Abstract

The invention relates to the technical field of cement pipe manufacturing, in particular to a high-strength composite cement pipe rapid forming mold which comprises a base, a first groove is formed in the center of the upper end of the base, a cylinder is fixedly connected to the center of the interior of the first groove, and a movable plate is movably connected to the position, close to the upper end, of the interior of the inner wall of the first groove. A mold is fixedly connected to the upper end of the moving plate, a first spring is fixedly connected to the lower end of the moving plate, air pipes are arranged at the positions, located on the lower portions of the two sides of the groove, in the base, pistons are movably connected to the interiors of the air pipes, and supporting plates are fixedly connected to the positions, close to the left side and the right side, of the upper end of the base; the upper end of the air pipe extends to the lower end of the interior of the supporting plate, the gravity of concrete during pouring is not increased too much, the two knocking plates continuously knock the outer side of the mold, in this way, the stacking effect can be achieved while air doped in the concrete is exhausted, and the quality of the concrete after solidification is improved.

Description

technical field [0001] The invention relates to the technical field of cement pipe manufacture, in particular to a high-strength composite cement pipe rapid prototyping die. Background technique [0002] Cement pipes have an important application in the process of urban water pipe network construction. At present, most of the cement pipes are poured by reinforced concrete. The specific pouring method is to put the steel bars into the mold, and then pour the concrete mortar into the mold. After the concrete is completely condensed and dried, open the mold and complete the pouring. . [0003] Existing patent (notification number: CN212218839U) rapid prototyping mold for cement pipes, a rapid prototyping mold for cement pipes, including an outer mold, an inner mold and a base, the inner mold is arranged inside the outer mold, and the outer mold is arranged on the base In the above, the outer mold includes a first outer mold and a second outer mold, support columns are provide...

AI Technical Summary

Problems solved by technology

[0004] In the above case, some problems of cement pipes were solved when demoulding. However, when large cement pipes were manufactured, concrete was poured into the mold and then left to solidify outdoors. At this time, there would be gas mixed Mixed into the interior of the concrete, this will have a great impact on the quality of the solidified concrete, and the concrete cannot be compacted after pouring:
