Two-way pressurization stable limiting brick making machine

Abstract

The invention discloses a two-way pressurization stable limiting brick making machine which comprises a fixing base. A fixing top plate is installed at the top end of the fixing base, a multi-pressureexhaust mechanism is installed at the bottom end of the fixing top plate, and the multi-pressure exhaust mechanism comprises a hydraulic rod, a connecting plate, pressing blocks, shells, sliding blocks, rubber plugs, multi-pressure springs, pressing plates, vent holes, exhaust holes, connecting ropes and rubber columns. According to the two-way pressurization stable limiting brick making machine,multi-stage pressure application can be conducted in the material pressing process through the multi-pressure exhaust mechanism, so that the material pressing process can be gradually increased stageby stage, pressure borne by materials in the material and shell separation process can also be gradually decreased stage by stage, and then the phenomenon that formed bricks break as the materials are suddenly subjected to huge pressure or separation in the material pressing process is avoided; and besides, air can be rapidly discharged in the material pressing process, meanwhile, the inner sidesof the vent holes can be cleaned when the shells are separated from the bricks, and the bricks can also be conveniently separated from the surfaces of the shells.

Description

technical field [0001] The invention relates to the technical field of brick making equipment, in particular to a two-way pressurized stable limit brick making machine. Background technique [0002] At present, the domestic mainstream wall material production equipment can be divided into two types: vibration forming and press forming according to the raw material forming method. Vibration forming is mostly suitable for concrete block products, while press forming is mostly used to produce wall material products based on powder raw materials. , Bricks are often processed using a two-way pressurized brick making machine during the production process; [0003] However, the brick-making machines currently on the market, in the actual use process, are all pressed down through the hydraulic rod, so that the pressure of the hydraulic rod on the material is constant, and the material is over-pressed to cause bricks At the same time, the pressed bricks are easy to stick to the surf...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a two-way pressurized stable limit brick making machine, which can effectively solve the problem that the current brick making machines on the market proposed in the above background technology, in the actual use process, are all pressed down by hydraulic rods, As a result, the pressure of the hydraulic rod to process the material is constant, and the excessive pressure of the material causes the brick to break after forming. At the same time, the pressed brick is easy to stick to the surface of the briquetting block, which makes it difficult The problem of demoulding
