Assembled type building block molding mould core

Abstract

The invention discloses an assembled type building block molding mould core comprising two long frameworks and a plurality of long separation plates, which are arranged in an array manner, wherein the two long frameworks are located at two sides of a mould core and the plurality of the long separation plates are located between the two long frameworks; short frameworks are arranged between the end parts of the long frameworks and the long separation plates and between the end parts of the adjacent long separation plates; short separation plates are connected between the long frameworks and the long separation plates and between the adjacent long separation plates; the short frameworks and the long frameworks or the long separation plates are connected through connecting bolts; the short separation plates and the long frameworks or the long separation plates are connected through the connecting bolts; and a region between the long frameworks and the short frameworks is divided into a plurality of building block molding cavities by the long separation plates and the short separation plates. The assembled type building block molding mould core has the beneficial effects of avoiding the deformation of the whole mould core in a carburization process. Meanwhile, the production efficiency, the machining precision and the whole precision are improved, and the cost is relatively lower.

Description

technical field [0001] The invention relates to the field of block forming molds, in particular to an assembleable block forming mold core. Background technique [0002] In recent years, the building block industry has developed vigorously in my country, making great contributions to infrastructure construction and the comprehensive application of industrial solid waste. Various block molds developed to meet different materials, shapes and functions play a very important role in the block production process. [0003] Accuracy and durability are important indicators for measuring block molds, and the structural design and processing methods of the mold core play an extremely important role in this. Traditional block mold cores are often formed by welding or wire cutting. The heat treatment process used is mainly carburizing and nitriding, and some carbonitriding is used. [0004] The welding form is to use small plate welding to make the mold core, and 60% of the block mold...

AI Technical Summary

Problems solved by technology

[0006] 1. At the intersection of welding, it needs to be manually polished to the angle required by the product design, so the error is large, it is difficult to control the intermission, and the production effect is slow

[0007] 2. The internal stress of the overall welded mold core is large. If the carburizing heat treatment is adopted in the later stage, the deformation cannot be avoided. After the deformation, it needs to be corrected and polished, which will further prolong the production cycle and increase the defective rate

In addition, the processing cycle of the nitriding process is much longer than that of carburizing
