Abstract

The invention belongs to the technical field of a brick pressing machine, and particularly relates to a demoulding mechanism of a brick molding press. The demoulding mechanism of the brick molding press comprises a base, a mould frame cross beam, a guide stand column and an upper cross beam, wherein the two ends of the guide stand column are fixedly connected with the upper cross beam and the base, so that a sealed frame is formed; the mould frame cross beam is positioned between the upper cross beam and the base, and can slide on the guide stand column; the demoulding mechanism has the structure key points that the mechanism also comprises two demoulding oil cylinders and four hinge support seats, wherein the two demoulding oil cylinders are symmetrically distributed at the two sides of the sealed frame, and the two ends of the demoulding oil cylinders are fixedly arranged on the upper cross beam and the mould frame cross beam by the four hinge support seats; each hinge support seat comprises a lug seat, a pin shaft, a check ring, a shaft sleeve and a bearing, wherein the pin shaft is fixed on the lug seat by the check ring; the bearing is installed on the pin shaft and is positioned at the two sides of the bearing for locating the bearing; and the two ends of the demoulding oil cylinders are provided with lug rings which are installed on the bearings of the hinge support seats. The demoulding mechanism of the brick molding press has simple structure and high reliability, and reduces the failure rate of equipment.

Description

The mould emptier of brick machine

Technical field

The invention belongs to brick machine tool technical field, particularly relate to a kind of mould emptier of brick machine.

Background technology

The mould emptier of the brick machine of prior art generally comprises entablature; the mould bases crossbeam; base; guide upright post; mould and demoulding oil jar; guide upright post is fixedlyed connected with entablature with base; form the framework of sealing; the mould bases crossbeam is between base and entablature; on guide upright post, slide; mould comprises upper punch; low punch and framed; low punch is fixedlyed connected with base; framedly fixedly connected with the mould bases crossbeam; the cylinder body end of demoulding oil jar is connected with the entablature hinge or is fixedly connected; tailpiece of the piston rod is fixedlyed connected with the mould bases crossbeam; like this; after brick machine was adobe compression moulding, the demoulding oil jar action drove the mould bases crossbeam and moves downward, thereby adobe is thrown off from mould; this process is the adobe demoulding; because of the existence of the guiding clearance between mould bases crossbeam and the guide upright post, cause the flexible movement locus of demoulding oil jar not overlap with the guide track of mould bases crossbeam in knockout course, demoulding oil jar is to fixedly connected with the mould bases crossbeam; cause the piston rod of demoulding oil jar not only to be subjected to the power of vertical direction; but also be subjected to the power of horizontal direction, thereby make demoulding oil jar generation eccentric wear cause bad seals, the oil cylinder easy oil leakage; the fault rate height, efficient is low.

Summary of the invention

The objective of the invention is to overcome the high and ineffective shortcoming of fault rate in the prior art, the mould emptier of a kind of brick machine that frame for movement is simple, reliability is high is provided.

For achieving the above object, the present invention is achieved through the following technical solutions:

The mould emptier of brick machine comprises entablature, mould bases crossbeam, guide upright post and base; fixedly connected with base with entablature in the two ends of guide upright post; form the framework of a sealing; the mould bases crossbeam is between entablature and base; and on guide upright post, slide; its structural feature also comprises demoulding oil jar and hinged-support, and the two ends of demoulding oil jar are fixed on entablature and the mould bases crossbeam by hinged-support.

Described hinged-support comprises ear seat, bearing pin, back-up ring, axle sleeve and bearing, bearing pin is fixed on the ear seat by back-up ring, bearing is installed on the bearing pin in the middle of the ear seat, and axle sleeve is installed on the bearing pin and is positioned at two of bearing and picks up the ears the centre of seat bearing to be carried out axial location.

Described bearing is a kind of oscillating bearing.

Described demoulding oil jar is the oil cylinder of two ends band earrings, and the two ends earrings is installed in respectively on the bearing of hinged-support, and hinged-support is fixed on entablature and the mould bases crossbeam.

Like this, demoulding oil jar is in expanding-contracting action, when the movement locus of mould bases crossbeam does not overlap with the movement locus of demoulding oil jar piston rod, regulate by the oscillating bearing on the hinged-support at demoulding oil jar two ends, make demoulding oil jar become two power bar force structures all the time, overcome the deflection wearing and tearing between demoulding oil jar cylinder body and the piston rod.

In sum, the present invention has the following advantages compared to existing technology: the mould emptier of this brick machine is simple in structure, and the reliability height in the service life of having improved demoulding oil jar, greatly reduces breakdown rate.
