Eccentric expansion brick-jacking mould device of brick press

Abstract

The invention discloses an eccentric expansion brick-jacking mould device of a brick press, which comprises a brick press body, a horizontal spindle, a connecting rod, a rocking bar, a pivoted vertical shaft, a support rod and a jacking mould, wherein the horizontal spindle axially interlocks rotational power, the horizontal spindle is provided with an eccentric wheel, and the eccentric wheel is sleeved with a running-fit sleeve; the middle part of the rocking bar is positioned by the pivoted vertical shaft by way of pin connection, the front end of the rocking bar can be in rotational pin connection with the support rod, and the rear end of the rocking bar can be in rotational pin connection with the lower end of the connecting rod; and the upper end of the connecting rod is fixedly connected with the running fit sleeve. The eccentric expansion brick-jacking mould device disclosed by the invention is simple in structure and precise in positioning, can achieve the technical effects of convenient assembling, disassembling and maintenance and small abrasion, and also can achieve the technical effect of realizing the internal installation of the eccentric wheel so as to simply an interlocking structure.

Description

technical field [0001] The invention relates to a turntable brick machine, in particular to an eccentric telescopic brick top mold device for a brick press. Background technique [0002] At present, such as Chinese patent ZL01220757.8 (authorized announcement date: January 2, 2002, authorized announcement number: CN2468694Y), a disclosed "disc rotary brick press" is mainly composed of a motor, a large and small pulley, and a reduction shaft. , large and small gears, crankshaft, connecting rod, ejector rod, piston, neutral shaft, rotary disc, mold body and so on. Its working principle is: the small pulley of the motor drives the big pulley belt for a first-stage deceleration, and also through the large and small gears for a second and third deceleration, and then drives the crankshaft installed on the body to drive the ejector rod hinged by the connecting rod and The piston on the ejector rod; the front end of the connecting rod is fixedly installed on the central vertical s...

AI Technical Summary

Problems solved by technology

The upper part of the ejector rod of this type of brick press ejector mold device extends into the piston and directly contacts the top surface of the piston cavity, resulting in easy wear between the top surface of the ejector rod and the top surface of the piston inner cavity. Increased wear causes the overall vibration of the brick machine to be large, shortening the service life of the brick press

The piston on the ejector rod needs an oil supply mechanism to keep lubricated, but due to the limitation of the interlocking structure, the eccentric position of the ejector rod is large, which makes it difficult to seal the oil cylinder of the interlocking piston and cause oil leakage, which causes waste and damage to the piston structure and cannot repair

Moreover, this type of structure is complex. Due to the high requirements for assembly accuracy, it is difficult to repair once worn out and must be replaced. This complex structure is not conducive to manufacturing processability, wear resistance and economy, and it is easy to wear and cause stacking. Now, the transmission is neither stable nor accurate, resulting in low machining accuracy and high scrap rate, and it is not conducive to equipment assembly, disassembly and maintenance, etc.
