Automatic pressing machine mold for cylindrical refractory bricks, fully-automatic hydraulic brick pressing machine and brick pressing process

Abstract

The invention provides an automatic pressing machine mold for cylindrical refractory bricks, a fully-automatic hydraulic brick pressing machine and a brick pressing process and belongs to the field of refractory brick production equipment. The automatic pressing machine mold comprises an upper mold plate, a lower mold plate and a middle frame. The middle frame comprises a central spindle and a side plate. The central spindle is arranged on the inner side of the lower mold plate. The side plate is arranged on the outer side of the lower mold plate. The middle frame and the lower mold plate relatively ascend and descend to form an annular mold cavity. The side plate is connected with a side plate lifting connecting part for driving the side plate to ascend and descend. The side plate lifting connecting part is movably arranged relative to the central spindle and can push the central spindle to ascend. The central spindle is connected with a central spindle demolding mechanism for driving the central spindle to descend. According to the automatic pressing machine mold for the cylindrical refractory bricks, a material uniformizing device is fixed to a material distribution trolley; the middle frame is connected with a floating mold frame and ascends and descends along with the floating mold frame; it is required that an auxiliary oil cylinder relieves pressure in the pressing molding process in the pressing process, and the floating mold frame is in the floating state; and the automatic pressing machine mold has the beneficial effects that the draft angle is small, the quality of the pressed refractory bricks is good, and continuous working can be achieved.

Description

technical field [0001] The invention relates to an automatic press mold for cylindrical refractory bricks, a fully automatic hydraulic brick press and a brick pressing process, belonging to the field of refractory brick production equipment. Background technique [0002] The refractory brick mold is the key equipment in the production process of refractory bricks. Its working conditions are extremely harsh, and it is subjected to high-stress abrasive wear and stress fatigue cracks of hard refractory particles. Therefore, the performance of the refractory brick mold will directly affect the production efficiency and quality of the refractory brick. The refractory brick molds currently used must be replaced and repaired after being used thousands of times. During brick making, the molds are often wiped to prevent the molds from sticking. The density of the upper and lower bricks is inconsistent; the replacement and repair of the mold requires manual work under the pressure he...

AI Technical Summary

Problems solved by technology

The currently used refractory brick molds must be replaced and repaired after being used thousands of times. During brick making, the molds are often wiped to prevent the mold from sticking. The density of the upper and lower bricks is inconsistent; the replacement and repair of the mold requires manual work under the pressure head of the press, which is very dangerous

At present, the molds of brick presses in the refractory industry have generally used metal splicing molds. The advantages of this mold are low cost, easy to replace, and easy to maintain. The disadvantage is that the draft angle is large, and the density of the pressed bricks is not uniform. , short continuous operation time and short life

At the same time, the structure and use of cylindrical refractory bricks are different from standard bricks and other perforated bricks. Therefore, there are higher requirements for the appearance and density of cylindrical refractory bricks. The mold of cylindrical refractory bricks must have inner formwork and The outer formwork generates tension when the cylindrical refractory brick is extruded, and it is easy to cause damage to the refractory brick when the inner formwork and the outer formwork are demoulded
