A kind of evaporative pattern chill clamping device
Technical field
The utility model relates to casting field, and what be specifically related to is a kind of evaporative pattern chill clamping device.
background content
Lost foam casting is generally directly be positioned in sandbox by evaporative pattern to pour into a mould.Foundry goods is because the wall unevenness of needs often each part of its structure, in the process of cooling, the position cooling that wall thickness is thicker is slow, and the position cooling that wall thickness is thinner is fast, the cooling velocity at each position differs, and easily causes ironcasting to produce shrinkage cavity or position drawing crack thin for wall.In addition, pour into a mould because evaporative pattern is directly placed in sandbox, after foundry goods cooling, need founding to take out, labour intensity is large, and production efficiency is low, also there is certain potential safety hazard.
Summary of the invention
In order to improve casting quality, reducing labour intensity, enhance productivity, the utility model provides a kind of evaporative pattern chill clamping device.
This evaporative pattern chill clamping device, comprises base, it is characterized in that, base is welded with 4 supports, and the top being respectively support one, support two, support three and support four, 4 supports is all welded with hanger; The middle part of support one, support two, support three is equipped with three, upper, middle and lower through hole, places an axis of guide in each through hole; The axis of guide in support one or three through holes all welds with chill plate one, the axis of guide in support two or three through holes all welds with chill plate two, the axis of guide in support three or three through holes all welds with chill plate three, and the bottom of chill plate one, chill plate two and chill plate three is placed on base respectively; The opposite side of support one, support two, support three is equipped with upper and lower two U-shaped frames, and the position of upper U-shaped frame is corresponding with upper through hole, and the position of lower U-shaped frame is corresponding with lower through-hole, is equipped with dismountable fixture block in upper and lower U-shaped frame; The side of support four is welded with chill plate four, and the bottom of chill plate four is welded on base.
During use, evaporative pattern is placed on chill plate one and chill plate two, base between chill plate three and chill plate four, moves chill plate one, chill plate two and chill plate three with spade, make it be close to evaporative pattern; Then between upper U-shaped frame and the axis of guide, put into fixture block, between lower U-shaped frame and the axis of guide, put into fixture block, now, evaporative pattern is clamped on base by chill plate one, chill plate two, chill plate three and chill plate four; Hook hanger with driving and whole device is put into sandbox, foundry goods can reach the object of cooling rapidly in casting cycle, reduces the size design of rising head.After cast cooling, then hung out by device with driving, unloading all fixture blocks can take out foundry goods.
Advantage of the present utility model: arrange fixing chill plate four, only need move other three blocks of chill plates when placing evaporative pattern, greatly reduce labour intensity; The foundry goods surrounding of pouring into a mould in evaporative pattern arranges chill plate, makes the cooling velocity of cast iron even, can prevent from wall thickness crossover sites and sharply change parts cracking, and can also prevent foundry goods from producing shrinkage cavity and porosity, substantially increase the quality of foundry goods.
