Abstract
The utility model discloses a low pressure casting riser tube insulation sleeve, which comprises an insulation sleeve body, wherein a plurality of heat emission holes are arranged on the side wall of the insulation sleeve body, a plurality of bosses which are used to wind resistance wires are uniformly convexly arranged on the outer wall of the insulation sleeve body from top to bottom at intervals, and a ring-shaped fixed outer sleeve is sleeved on the lower end of the insulation sleeve body. The insulation sleeve body can be fixed on a riser tube through the ring-shaped fixed outer sleeve, and screw holes which are correspondingly fixed are arranged on the insulation sleeve body and the ring-shaped fixed outer sleeve. The low pressure casting riser tube insulation sleeve has the advantages of simple structure and convenient operation and the like, can effectively increase temperature of a riser tube mouth, reduces heat loss of molten aluminum in a furnace, can effectively control the temperature of the riser tube mouth, achieves progressive solidification of low pressure castings, enhances feeding, obtains castings with compact inner portion, and plays the role of effective guarantee.
Description
Technical field
The utility model belongs to the aluminum alloy low-pressure casting field, particularly relates to a kind of low-pressure casting lift tube muff.
Background technology
At present, the domestic low pressure casting that uses in the 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 that uses in low pressure casting 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 descends.
The utility model content
The purpose of this utility model is exactly defective and the deficiency that exists 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 stalk muff can effectively improve stalk mouth temperature, reduces aluminium liquid heat loss in stove, can effectively control the temperature of stalk mouth, and the low pressure casting foundry goods is realized consecutive solidification, strengthens feeding, obtains the foundry goods of interior solid, plays effective assurance.
The technical scheme that adopts is:
A kind of low-pressure casting lift tube muff, comprise the muff body, offer a plurality of louvres on the sidewall of the muff body under it is characterized in that, on the outer wall of muff body from bottom to top the interval convex with uniformly a plurality of boss for being wound around resistance wires, the lower end cover of muff body only has annular fixed jacket.The muff body can be fixed on stalk by described annular fixed jacket.Offer corresponding fixing screw on muff body and annular fixed jacket.
The utlity model has the advantages such as simple in structure, easy to operate, can effectively improve stalk mouth temperature, reduce aluminium liquid heat loss in stove, can effectively control the temperature of stalk mouth, the low pressure casting foundry goods is realized consecutive solidification, strengthen feeding, obtain the foundry goods of interior solid, play effective assurance.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is that the utility model is sleeved on the schematic diagram on stalk.
The specific embodiment
A kind of low-pressure casting lift tube muff, comprise muff body 1, offer a plurality of louvres 2 on the sidewall of muff body 1, on the outer wall of muff body 1 from bottom to top the interval convex with uniformly a plurality of boss 3 for being wound around resistance wires, 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.Offer corresponding fixing screw 6 on muff body 1 and annular fixed jacket 4.
