Device, solves that water-glass sand recovery utilization rate is low in traditional railway cast steel wheel production technology, and the discharge of a large amount of antiquated sand influences
The problem of periphery Ecological environment.
To solve above-mentioned technical problem, the utility model uses following technical scheme：
A kind of device for railway cast steel wheel V method graphite Quench gravity foundry technologies, including it is equipped with the upper of shaping
The cope of graphite annulus and be equipped with shaping lower graphite annulus drag box, be provided with cope and be made of V method formative technologies
Mo(u)ld top half, be provided with drag box and use mo(u)ld bottom half made of V method formative technologies, the cavity between mo(u)ld top half and mo(u)ld bottom half is die cavity, pours and emits
Mouth is arranged on mo(u)ld top half and corresponded to above wheel hub, lays floating core and the core that drenches with rain successively from top to bottom in the bottom of mo(u)ld top half dead head,
Mo(u)ld bottom half lays the bottom connection of SMIS, the top of SMIS and the core that drenches with rain.
Poured into a mould using rising pouring bag, molten steel injects die cavity through dead head, floating core, the small cast gate of the core that drenches with rain during cast, treats that molten steel fills
To when setting riser height, cast terminates type, floats core and floats, the core center Feeding channel that drenches with rain is opened, and is emitted intraoral molten steel and is continued
Feeding is carried out to wheel body, rim for automobile wheel quickly solidifies in the presence of graphite annulus Quench, forms the tissue of densification, while
In the presence of central dead head, realize from wheel rim to disc again to the consecutive solidification of wheel hub, after feeding terminates, output mo(u)ld top half
Rising head is pulled out along the core that drenches with rain simultaneously, then takes wheel, sandbox pressure release, knockout, after magnetic separation, dedusting, cooling, online circulation makes antiquated sand
With, after graphite annulus forces cooling, also online recycling.
As it is of the present utility model further preferably, above-mentioned upper graphite annulus and lower graphite annulus are located at the outer of corresponding rim for automobile wheel
Side.
Compared with prior art, the utility model can at least reach one in following beneficial effect：
1. for V methods casting technique at home using mature and stable, its advantage is that moulding quartz sand need not add bonding
Agent, cyclic utilization rate can effectively solve water-glass sand regeneration in traditional railway cast steel wheel casting technique and return up to more than 95%
The problem of utilization rate is low is received, the consumption of quartz sand and the discharge of antiquated sand are greatly reduced, beneficial to the control of wheel manufacturing cost
With influence of the reduction to ecological environment.
2. graphite chilling block technique at home using maturation, its advantage is that the big chill effect of graphite heat conducting coefficient is good, by
Mo(u)ld top half and mo(u)ld bottom half correspond to rim for automobile wheel lateral surface and set upper graphite annulus and lower graphite annulus, effect of the rim for automobile wheel in graphite annulus Quench
Lower quick solidification, forms the tissue of densification, while in the presence of central dead head, realize and arrive wheel hub again from wheel rim to disc
Consecutive solidification.
