Mould for extruding and forming sintering heat preservation building block

Abstract

The invention relates to a mould for extruding and forming a sintering heat preservation building block, which belongs to the technical field of construction material machines. The mould comprises three parts of a machine head, a machine opening and a core bracket. The machine head is in a cone-shaped cylinder shape, a big end is a circular opening, a small end is a rectangular opening; the upper direction, the lower direction, the left direction and the right direction of the surface of a cylinder body of the machine head are provided with 4 groups of mud regulation inserting plates, the small end of the machine head is connected with the machine opening, and the core bracket is installed in the machine opening and connected with the end face of a flange of the machine opening by a fixed press plate of the core bracket; the machine opening comprises the flange of the machine opening, a baffle plate of the machine opening, a panel of the machine opening, mud regulation blocks and a press strip, and internal openings of the components are kept concentric and are fixed into a whole by bolts sequentially. Firstly, in the invention, the upper direction, the lower direction, the left direction and the right direction of the machine head are provided with the mud regulation inserting plates, therefore, the full orientation regulation of the extruded mud is realized, the flow direction and the flow rate of the mud can be effectively controlled, extrusion pressure is balanced and the mud flow is uniform and is pushed ahead. Simultaneously, the four faces of the machine opening are designed with the 32 mud regulation blocks, and each block can be independently regulated, thereby ensuring the uniformity of the wall thickness of the extruded building block. The core bracket is an independent component relative to the whole set of mould and can be quickly replaced according to the production requirement in use.

Description

Technical field [0001] The invention belongs to the technical field of building materials machinery manufacturing, in particular to a novel sintered thermal insulation block forming equipment. Background technique [0002] According to recent relevant information, my country’s total annual energy consumption is close to 3 billion tons (standard coal equivalent), and building energy consumption accounts for 30% of the total social energy consumption, of which heating and cooling account for approximately 50% of building energy consumption. -80%, therefore, building energy efficiency is of great significance. [0003] The main body of the building is the wall, and the main material for the masonry wall (which is also proven to be the best for long-term use) is sintered bricks. However, ordinary sintered bricks are difficult to meet the current standards of 50% building energy saving throughout the country. Therefore, sintered porous thin-walled heat-preserving and heat-insulating blo...

Problems solved by technology

[0007] The traditional hollow brick mold is basically a transition from the machine mouth of the solid brick. A simple core frame is installed in the rectangular machine mouth of the solid brick. It can neither effectively adjust the direction of the extruded mud and maintain pressure balance, nor can it Solve the technical requirements such as thin wall, many holes, and large shape of sintered thermal insulation blocks. Therefore, it is impossible to use traditional hollow brick extrusion dies to produce sintered thermal insulation blocks
