Concrete product forming process

Abstract

The invention discloses a concrete product forming process. The concrete product forming process comprises the following steps: firstly, manufacturing an outer mold cavity or an inner mold core of a concrete product by utilizing an industrial paraffin material; fixing the prepared outer mold cavity or inner mold core in a mold for preparing the concrete product; then injecting prepared concrete into a cavity formed by the outer mold cavity or the inner mold core and the mold; and finally, after the concrete product is solidified, opening the mold, melting the paraffin, and the taking out the concrete product. According to the concrete product forming process, the processing problem of concrete products with special structures and difficult demolding can be solved, the mold structure is simple, the manufacturing time is short, the universality is high, and the mold investment cost is greatly reduced.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a molding process for concrete products. Background technique [0002] The molding process of existing concrete products is a process in which the designer designs the mold structure according to the shape and size of the concrete product, injects concrete into the cavity of the mold and after the concrete solidifies, disassembles the mold and takes out the concrete product. [0003] The main problems in the molding process of existing concrete products are: [0004] 1. For some concrete products with special structures, such as hollow concrete products, the holes of concrete products are large inside and small outside, etc., it is an impossible task for traditional molds, and the structure of concrete products can only be adjusted; [0005] 2. When the mold is designed, if the demoulding slope is unreasonable, the mold will jam, which will make it difficult to ...

AI Technical Summary

Problems solved by technology

[0004] 1. For some concrete products with special structures, such as hollow concrete products, the holes of concrete products are large inside and small outside, etc., it is an impossible task for traditional molds, and the structure of concrete products can only be adjusted;

[0005] 2. When the mold is designed, if the demoulding slope is unreasonable, the mold will jam, which will make it difficult to disassemble the mold or damage the corners of the concrete product;

[0006] 3. The mold structure is complex and the manufacturing requirements are high, which makes the mold cost very high;

[0007] 4. The mold design and manufacturing cycle is long, which generally takes two months. If the product structure is complex, it will take more time, which cannot meet the customer's requirements;

[0008] 5. The mold configuration specifications of concrete product production enterprises are large and the quantity is large, resulting in excessive investment in the mold costs of the enterprise, which affects the economic benefits of the enterprise
