Concrete die with shape changed according to specifications of prefabricated block

Abstract

The invention discloses a concrete die with a shape changed according to the specifications of a prefabricated block. The concrete die comprises a working table surface, wherein electric telescopic rods are symmetrically arranged on the upper surface of the working table surface; a first die is arranged at an output end of each electric telescopic rod; each first die is located between two seconddies, and V-shaped grooves are formed in the opposite surfaces of the two first dies; four support rods are uniformly arranged at the outer side of the upper surface of the working table surface; a slide sleeve is arranged at the outer side of each support rod, and a top plate is arranged at the upper ends of the four support rods; and an output end of an electric push rod penetrates through the top plate and is provided with press plates connected with the slide sleeves. According to the concrete die, the first dies are driven to move through the electric telescopic rods to realize adjustmentfor a distance between the first dies; and a shape between the first dies and the second dies can be changed into a rhombus or a hexagon, and the shape can be changed according to the specifications,so that resource waste is avoided.

Description

technical field [0001] The invention belongs to the technical field of concrete molds, in particular to a concrete mold whose shape is changed according to the specifications of prefabricated blocks. Background technique [0002] Concrete is one of the most important civil engineering materials in the contemporary era. It has the characteristics of abundant raw materials, low price, simple production process, arbitrary shape and high rigidity. At the same time, concrete also has the characteristics of high compressive strength, good durability and wide range of strength grades. , Concrete mold is a tool for forming concrete components. According to the different structures to be formed, it can form concrete cast-in-place molds such as beams, columns, walls, wells, etc. Concrete molds generally include plastic injection molding and sheet metal steel mold molding Two types, the concrete plastic mold is made of polypropylene plastic granules, which are injected into the pre-pre...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a concrete mold that changes shape according to the specifications of the prefabricated blocks, so as to solve the problem that the existing molds proposed in the background technology cannot change the shape according to the specifications, and can only be used for the manufacture of one kind of prefabricated blocks, resulting in resource constraints. Wasteful, labor-intensive and time-consuming; at the same time, it does not have the effect of compaction, and the structure of the concrete prefabricated block is poor; and the concrete mold is inconvenient to disassemble, and the cleaning effect of the concrete at the included angle is poor; in addition, the stability of the existing mold is poor , it is easy to cause the displacement of the whole mold due to mechanical vibration
