Extrusion molding device for environment-friendly brick production

Abstract

The invention discloses an extrusion molding device for environment-friendly brick production. The extrusion molding device comprises a base table, wherein two sets of stand columns are symmetrically welded to the upper end of the base table, a lifting plate is slidably connected between the two sets of stand columns, a supporting plate is fixedly welded to the upper ends of the two sets of stand columns, a first electric push rod is fixedly installed on the supporting plate through a fixing frame, one end of a piston rod of the first electric push rod penetrates through the supporting plate and is fixedly connected to the upper surface of the lifting plate, a forming assembly is fixedly installed at the upper end of the base table, the lower end of the lifting plate is fixedly connected with a cover plate used in cooperation with the forming assembly through a connecting column, and a storage box is arranged at the upper end of the supporting plate and communicates with three sets of discharging pipes. A piston block is driven by a second electric push rod to ascend and descend, the ascending and descending of the piston block can adjust the pressure in a shell, in cooperation with one-way valves arranged on a first material pipe and a second material pipe, material pumping and injecting from a material storage box are achieved, and the problem that existing manual extrusion and injecting cannot ensure the same extrusion amount each time is solved.

Description

technical field [0001] The invention belongs to the technical field of production of environmental protection bricks, and in particular relates to an extrusion molding device for production of environmental protection bricks. Background technique [0002] Manufactured by using fly ash, coal slag, coal gangue, tailings slag, chemical slag or natural sand, sea mud, industrial waste, waste incineration slag, etc. (one or more of the above raw materials) as the main raw materials without high-temperature calcination A new type of wall material is called environmentally friendly bricks. Environmentally friendly bricks have high strength, good durability, standard size, complete shape, uniform color, and a simple and natural appearance. They can be used as clear water walls or as any external decoration. A very promising replacement product to replace clay bricks. [0003] In the production process of environmentally friendly bricks, the raw materials need to be prepared into a p...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide an extrusion molding device for the production of environmentally friendly bricks, to solve the problem that in the prior art manual extrusion injection cannot ensure the same amount of extrusion each time, and the amount of extrusion injection is too much. It is easy to make the corners of the adobe with burrs, but too little extrusion material will cause the adobe to form a hollow, resulting in poor production of environmentally friendly bricks
