Abstract
The invention discloses a riser tube insulation jacket for low-pressure casting. The riser tube insulation jacket comprises an insulation jacket body, wherein a plurality of heat emission holes are formed in the side wall of the insulation jacket body; a plurality of bosses wound with resistance wires are formed at uniform intervals in a projecting manner on the outer wall of the insulation jacket body from bottom to top; the lower end jacket of the insulation jacket body is only an annular fixing jacket; the insulation jacket body can be fixed to a riser tube through the annular fixing jacket; corresponding fixing screw holes are formed in the insulation jacket body and the annular fixing jacket. The riser tube insulation jacket has the advantages of simple structure, convenience in operation and the like, the orifice temperature of the riser tube can be raised effectively, the dissipation of the heat of molten aluminum in a furnace is reduced, the orifice temperature of the riser tube can be controlled effectively, sequential condensing of castings cast under low pressure is realized, feeding is enhanced, and manufacturing of internally-dense castings is ensured effectively.
Description
Technical field
The invention belongs to aluminum alloy low-pressure casting field, particularly relate to a kind of low-pressure casting lift tube muff.
Background technology
At present, the domestic low pressure casting using in aluminum alloy low-pressure casting field mostly is cast iron quality and the large class of ceramic material two with stalk, and cast iron quality is easy because of the fast temperature control of its heat conduction, and what in low pressure casting, use is comparatively general, but make cylinder iron stalk, in the casting later stage of low pressure casting, aluminium liquid surface is lower, and heat loss is larger, in order to improve the temperature of stalk mouth, designed a kind of electrically heated muff, to improving the temperature of stalk mouth, the temperature that reduces aluminium liquid declines.
Summary of the invention
Object of the present invention is exactly defect and the deficiency existing for overcoming above-mentioned prior art, and a kind of simple in structure, easy to operate low-pressure casting lift tube muff is provided.This kind of stalk muff, can effectively improve stalk mouth temperature, reduces aluminium liquid heat loss in stove, can effectively control the temperature of stalk mouth, and low pressure casting foundry goods is realized to consecutive solidification, strengthens feeding, obtains the foundry goods of interior solid, plays effective assurance.
The technical scheme adopting is:
A kind of low-pressure casting lift tube muff, comprise muff body, on the sidewall of the muff body under it is characterized in that, offer multiple louvres, on the outer wall of muff body, interval convexes with multiple boss for being wound around resistance wire uniformly from bottom to top, and the lower end cover of muff body only has annular fixed jacket.Muff body can be fixed on stalk by described annular fixed jacket.On muff body and annular fixed jacket, offer corresponding fixing screw.
The present invention has the advantages such as simple in structure, easy to operate, can effectively improve stalk mouth temperature, reduces aluminium liquid heat loss in stove, the temperature that can effectively control stalk mouth, realizes consecutive solidification to low pressure casting foundry goods, strengthens feeding, the foundry goods that obtains interior solid, plays effective assurance.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Fig. 2 is that the present invention is sleeved on the schematic diagram on stalk.
The specific embodiment
A kind of low-pressure casting lift tube muff, comprise muff body 1, on the sidewall of muff body 1, offer multiple louvres 2, on the outer wall of muff body 1, interval convexes with multiple boss 3 for being wound around resistance wire uniformly from bottom to top, and the lower end of muff body 1 is equipped with annular fixed jacket 4.Muff body 1 can be fixed on stalk 5 by described annular fixed jacket 4.On muff body 1 and annular fixed jacket 4, offer corresponding fixing screw 6.
