Abstract

The invention relates to a mold stripping method for a brick. The method is implemented by changing the size and shape of a brick supporter and arranging a brick discharging fork plate. After a brick body, a mold core, a brick cushion, the brick supporter and a brick discharging supporter are totally lifted out of a mold sleeve and the upper plane of the brick discharging supporter is aligned with the upper plane of the mold sleeve, the brick discharging fork plate is inserted below the brick cushion along the side edge of the brick supporter. Due to the adoption of the method, the mold stripping difficulty of the brick is reduced greatly and the problems of high labor intensity, low yield of a product, potential safety hazard and the like existing in the mold stripping process of a brick cup for producing a large single heavy round pouring box for continuous casting are solved. The method and a device have the advantages of simple structure, easy operation, safety, reliability and the like.

Description

A kind of mold stripping method of brick

Technical field

The present invention relates to the refractory material forming field, relate in particular to a kind of mold stripping method of brick.

Background technology

The employing of continuous casting process in the STEELMAKING PRODUCTION requires the tundish brick cup to have strict appearance and size and higher anti-erosion, thermal shock resistance, so the brick volume density is bigger, brick body substance is bigger, generally more than 30kg.The conventional method of producing the tundish brick cup is: see Fig. 8, Fig. 9; After the moulding during depanning; Operating personnel bend on workbench, and elder generation is clamping brick body with the hands, then die head core rod, brick pad, brick holder is fallen; After treating that core rod, brick pad, brick holder are withdrawn in the die sleeve fully, just the brick body is moved on the work edge of table from die sleeve die cavity top.This process has two drawbacks, and operating personnel's health is under the die head all the time during the one side depanning, if this moment, die head plunked down owing to fault is out of control, concerning operating personnel, will cause personal injury; On the other hand because brick body substance big

; Labour intensity is big during depanning; At core rod, brick pad, when the brick holder falls; Operating personnel take incessantly easily, and the brick body glides the brick body; Thereby make brick body lower limb collision type cavity edge, cause " gnawing the limit ", reduce the goods yield rate.

Summary of the invention

The mold stripping method that the purpose of this invention is to provide a kind of brick has solved when the circular brick cup of big substance molds mould in the traditional mode of production, and labor intensity of operating staff is big, and the goods yield rate is low, has the problem of potential safety hazard.

The object of the invention realizes through following technical scheme:

A kind of brick mold stripping method, this method through improving the brick holder size and dimension and install brick output fork plate additional and realize, specifically may further comprise the steps:

1) lift die head, when the brick output device moved upward, die sleeve was all enumerated in brick body, core rod, brick pad, brick holder, brick output holder thereupon, and on plane and the die sleeve stop simultaneously the time in the plane to the brick output holder, and brick output is pitched plate below the side of brick holder is inserted into the brick pad;

2) the brick output device is descended, brick output holder, brick holder, core rod are also fallen thereupon, reduce to core rod and sink to fully in the die cavity of die sleeve; This moment, brick pad and brick body were stayed on the brick output fork plate; The brick body is taken out, again the brick pad is put back in the brick holder in the die cavity, carry out the filler of next brick body then.

Cut edge less than brick pad appearance and size in the appearance and size both sides of described brick holder, the appearance and size of brick output fork plate is greater than brick pad appearance and size, and the interior shape of the outside side cut shape of brick holder and brick output fork plate is complementary.

Described brick holder is the shape that an annulus symmetry cuts both sides, and brick output fork plate is provided with two prongs, and the size between spacing and brick holder are cut edge in two prongs is complementary.

Described brick output fork plate thickness is thinner than brick holder, and tooth length is longer than brick body diameter.

The invention has the beneficial effects as follows: solved the production continuous casting and gone out in the mold process with the circular tundish brick cup of big substance, labor intensity of operating staff is big, and the goods yield rate is low, has problems such as potential safety hazard.This method and apparatus has simple in structure, processing ease, advantage such as safe and reliable.

The specific embodiment

Be described in detail the present invention below in conjunction with description of drawings.

1. charging; See Fig. 1,

At first in die sleeve 8 holes, drop to correct position, the brick material is evenly poured in the space between core rod 3 and the die sleeve 8 to brick output device 7, brick output holder 6, brick holder 5, brick pad 4.

2. compacting; See Fig. 2,

Die head 1 is depressed, be enclosed within on the core rod 3, with the downward compression moulding of brick material.

3. depanning; See Fig. 3,

Lift die head 1; Brick output device 7 moves upward then; Die sleeve 8 is all enumerated in brick body 2, core rod 3, brick pad 4, brick holder 5, brick output holder 6 simultaneously thereupon; Lift to brick output holder 6 on the plane and die sleeve 8 plane and stop simultaneously the time, below the side cut of brick holder 5 was inserted into brick pad 4, the crown of brick output fork plate 9 was carried on a shoulder pole over there on the die sleeve a brick output fork plate 9.

4. take brick; See Fig. 4, Fig. 5

Brick output device 7 is fallen; Brick output holder 6, brick holder 5, core rod 3 also descend thereupon, drop in the die cavity that core rod 3 sinks to die sleeve 8 fully always, and brick pad 4 is then stayed on the brick output fork plate 9 with brick body 2; At this moment operating personnel slide into brick pad 4 and brick body 2 on the work edge of table along brick output fork plate 9; Brick body 2 is taken out, again brick pad 4 is put back in the brick holder 5, carry out the filler of next brick body then.Because operating personnel are very of short duration in the time that die head stops for 1 time, thus greatly reduce the risk that personal injury occurs, and saved the process of hand-held brick body 2 demouldings of operating personnel.Because brick body 2 substances are too big, this is a step that labour intensity is very big, has therefore largely reduced labour intensity.On the other hand,

brick pad

4 and 2 depannings simultaneously of brick body have avoided " gnawing the limit " to guarantee the external form of brick body 2, have improved yield rate.

See Fig. 6, Fig. 7, a kind of novel demoulding device comprises brick holder 5 and brick output fork plate 9, and brick holder 5 is to have the annulus that two symmetrical, parallel are cut edge, and external diameter is less than the die cavity internal diameter of die sleeve 8; Brick output fork plate 9 is flat board forks of one two tooth, and two tooth inner edges are parallel, and interior spacing B and brick holder 5 side cut dimension D are complementary.Described brick output fork plate 9 thickness are thinner than brick holder 5, and tooth length is longer than brick body 2 diameters.

Brick output fork board size is according to concrete brick body dimensioned, and material can according to circumstances adopt metal, plastics or other strength and toughness material preferably.
