Forming mold with oscillation structure for precast concrete pipes

Abstract

The invention discloses a forming mold with an oscillation structure for precast concrete pipes. The forming mold comprises a base, wherein an outer mold and an inner mold are arranged above the base,a bottom plate is arranged between the outer mold and the inner mold, the lower end face of the bottom plate is fixedly installed in the base through supporting rods, the bottom plate is of an annular structure, a cover plate is mounted at the top end of the outer mold, a striking block is mounted on a rotating shaft, an oscillation block is arranged on the side of the striking block, an oil inlet pipe is arranged outside the outer mold, a first cavity is formed in the outer mold, a second cavity is formed in the inner mold, the bottom end of the second cavity communicates with a third lantern ring, and an oil outlet pipe is installed at the bottom end of the third lantern ring. According to the forming mold with the oscillation structure for precast concrete pipes, through the synchronous reverse rotation mode of the inner mold and the outer mold and in cooperation with efficient oscillation of the oscillation structure, concrete raw materials are distributed more evenly, the precastpipe forming quality is improved, and the structural design is more reasonable.

Description

technical field [0001] The invention relates to the technical field of molds for concrete products, in particular to a molding mold for concrete prefabricated pipes provided with an oscillating structure. Background technique [0002] Concrete prefabricated pipe refers to the tubular structure processed by using concrete as the main skeleton material. Because it is processed and prefabricated before actual application, it is called prefabricated pipe. It is widely used in municipal engineering and other fields. The overall shape regularity requirement is high, so the prefabricated tube needs to use the corresponding forming mold when manufacturing, but the existing forming mold has the following problems in actual use: [0003] 1. Most of the existing prefabricated pipe processing methods are that workers add materials in real time and put them into the rotating mold. After the general molding, the mold is taken out and left to stand. During the molding process, the concrete...

Problems solved by technology

[0005] The purpose of the present invention is to provide a forming mold for concrete prefabricated pipes provided with an oscillating structure, so as to solve the problem of the existing prefabricated pipe processing methods proposed in the above-mentioned background technology. The mold is taken out and left still, and the concrete raw materials cannot be subjected to secondary shock treatment during the forming process, so the defective rate of the formed concrete pipe is high in the case of uneven distribution of concrete; the forming process does not have the function of rapid prototyping, and the forming process During the process, due to the large amount of moisture in the raw materials, the way of natural drying greatly reduces the forming efficiency of prefabricated tubes, and because the drying operation is mostly carried out by unilateral external heating in the existing structure, the heating efficiency is low. question
