Description
Technical Field
The utility model relates to a cast technical field of wheel hub especially relates to a long-life rising head external member convenient to change.
Background
The riser part of the low-pressure die is usually installed in a matching way with the sprue bush, generally, after aluminum liquid enters from the sprue bush, the aluminum liquid contacts the riser part at the first time, and the phenomena of corrosion, cracking and the like of the riser part can be caused by long-time high-temperature scouring, so that off-machine maintenance is caused, and the production continuity is influenced. At present, a common maintenance method is repair welding and polishing, but after maintenance on a machine for die casting, corrosion occurs again and repair welding is needed, after continuous repair welding for many times, materials are fatigued, and can be corroded again in a short time, even cracks are expanded to other parts, at the moment, a bottom die needs to be newly manufactured, so that great labor intensity and cost expenditure of personnel are caused, and a reliable anti-corrosion solution is urgently needed to be found out.
The riser is a channel for the aluminum liquid to enter, and a heat preservation design is needed for the temperature and subsequent feeding of the aluminum liquid, but the integral riser is mostly adopted at present, only a sprue bush and refractory mortar are used for heat preservation, and other effective heat preservation means are not available.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model provides a conveniently-replaced long-life riser sleeve capable of delaying the corrosion time of a riser of a bottom die, which adopts an anti-corrosion material to manufacture the riser of the bottom die and prolongs the service life of the riser; when the riser of the bottom die reaches the service life, only a new anti-corrosion part needs to be replaced, and the processes of repair welding, polishing and the like are not needed.
In order to achieve the above purpose, the utility model is realized by adopting the following technical scheme:
the utility model discloses a long-life rising head external member convenient to change, including die block main part, anticorrosion part and heat preservation part, the die block main part is at rising head part movable mounting anticorrosion part and heat preservation part, anticorrosion part and heat preservation part are ring shape, the lower extreme of anticorrosion part is the wedge form and cooperates with the heat preservation part.
Preferably, the thickness of the corrosion prevention part is 2-4 mm.
Preferably, the material of the corrosion prevention part is tungsten-molybdenum alloy Mo-30W.
Preferably, the thickness of the heat preservation part is 2-4 mm.
Preferably, the heat preservation part is made of ZrO2A ceramic.
Preferably, the corrosion prevention portion and the heat preservation portion are mounted on the bottom die main body by screws.
Compared with the prior art, the beneficial effects of the utility model are that: according to the hub modeling, the anti-corrosion part and the heat preservation part are movably installed, the anti-corrosion part can delay the corrosion time of the riser of the bottom die, the service life of the riser is prolonged, and meanwhile due to the split design, when the service life of the riser of the bottom die is reached, only a new anti-corrosion part needs to be replaced, the time and energy are wasted due to processes such as repair welding and polishing, and the like, the machine can be immediately operated for die casting, and the production continuity is improved; the heat preservation part can strengthen the heat preservation effect of the riser, strengthen the flowing and feeding of the aluminum liquid and improve the die casting yield.
