A vacuum brick extruder mold

Abstract

The invention relates to a vacuum brick squeezing machine mold, and further relates to a method for squeezing bricks through the brick squeezing machine mold. The vacuum brick squeezing machine mold comprises a machine opening, a core tool and a machine head. The machine opening and the machine head are combined together to form a brick squeezing profile cavity. The core tool is installed on the machine head and comprises a hollow core frame body, a hollow core rod and a hollow core head, wherein the two ends of the core rod are connected with the core frame body and the core head respectively in a threaded mode, the interior of the core frame body, the interior of the core rod and the interior of the core head are communicated with each other to form a flow guide pipeline, and holes for lubricating agents to leak are formed in the surface of the core frame body, the surface of the core rod and the surface of the core head. The vacuum brick squeezing machine mold and method have the advantages that a through hole pipeline in the core frame body is connected with a through hole of the core rod so that the lubricating agents in the core frame body can enter the core rod, an inner pipeline of the core rod is communicated with an inner profile cavity of the core head so that the lubricating agents in the core rod can enter the inner profile cavity of the core head, and therefore the core tool can be lubricated.

Description

technical field [0001] The invention relates to a mold for a vacuum brick extrusion machine, and also relates to a method for extruding bricks by using the brick extrusion mold. Background technique [0002] With the promotion and use of new wall materials, the application field of vacuum brick extruders continues to expand, the corresponding equipment develops rapidly, and the requirements for forming molds for key components gradually increase. At present, the commonly used molding dies have a solid core body, core rod and core head. The wear amount can only be reduced by adding high-strength wear-resistant materials on the surface. Once the wear-resistant materials are worn away, it is necessary to It is replaced as a whole, and high-strength wear-resistant materials are expensive and costly to use. Therefore, the deficiencies in the wear resistance and smoothness of the working surface not only affect the service life of the mold, but also directly affect the surface qu...

AI Technical Summary

Problems solved by technology

At present, the commonly used molding dies have a solid core body, core rod and core head. The wear amount can only be reduced by adding high-strength wear-resistant materials on the surface. Once the wear-resistant materials are worn away, it is necessary to Overall replacement, and high-strength wear-resistant materials are expensive and costly to use

Therefore, the deficiencies in the wear resistance and smoothness of the working surface not only affect the service life of the mold, but also directly affect the surface quality of the extruded product.
