Description
Technical field
The utility model belongs to casting technology field, relates to high-temperature fusant casting metallurgical technology equipment, specifically refers to a kind of combined high-temperature melt stalk.
Background technology
The high-temperature fusant stalk is the essential a kind of technological equipment of low pressure casting.During low pressure casting, high-temperature fusant enters casting mold by stalk, and the melt in the casting mold is in certain Under Pressure Solidification moulding.After the release, the not solidified melt of part can flow in the melt crucible by stalk.
At present, domestic casting factory and workshop, the stalk that the low pressure casting high-temperature fusant adopts is divided into metal solder moulding and non-metallic refractory moulding two classes.The advantage of metal solder moulding stalk is easily manufactured, and is not fragile, and its shortcoming is the erosion that is subject to high-temperature fusant, and contaminated melt affects the foundry goods chemical composition, is not suitable for low pressure casting and produces continuously; And the advantage of nonmetal refractory material moulding stalk is the erosion of high temperature resistant melt, good heat insulating, and suitable low pressure casting is produced continuously, and shortcoming is that sealing joint is relatively poor, cracky.
Therefore, all there is obvious defective in two kinds of stalks that present domestic low pressure casting high-temperature fusant adopts, and its service life is all lower, affects production efficiency.
Summary of the invention
The purpose of this utility model is a kind of combined high-temperature melt stalk of design, makes it have detachably, easily assemble, the erosion of high temperature resistant melt, and good heat insulating, sealing joint is good, cracky not, the characteristic of long service life.
The technical solution of the utility model is: a kind of combined high-temperature melt stalk of the present utility model comprises the support ring platform on body and body top, the support ring platform is apart from body oral area certain distance H, body and support ring platform place on the bearing, the support ring platform is embedded in the annular groove of bearing, the body on support ring platform top has cover plate outward, cover plate is connected with the support ring platform by screw, bearing and cover plate are carbon steel or other metal materials, and the support ring platform on body and body top adopts alumina titanate ceramics, graphite or other high temperature resistant nonmetallic materials
On the contact-making surface of described cover plate and support ring platform flexible gasket is arranged.
Described combined high-temperature melt stalk is at two suspension ring of the symmetrical installation in the support ring platform outside.
The degree of depth of the annular groove of described bearing equals the thickness of support ring platform.
The thickness of described cover plate adds that the thickness of flexible gasket equals support ring platform top body upper height H, H=15～20mm.
Described body upper end endoporus is with the horn mouth of θ=5 °～10 °.
The thickness of described flexible gasket 7 is 2mm～5mm.
Advantage of the present utility model:
(1) weight capacity is strong, and is not fragile; The load-bearing of metal connecting tube body, nonmetal body are difficult for damaging.
(2) erosion resisting is good, can prevent effectively that melt from increasing iron; The metal connecting tube body does not contact with melt, can prevent effectively that melt from increasing iron;
(3) good airproof performance.Adopt the sealing of multilayer asbestos pad, good airproof performance, Leakage Gas is few.
(4) design of part is simple, and is easily manufactured, is easy to dismounting and replacing.
