Description
Technical field
The utility model relates to a kind of processing apparatus of solvent casting, is specifically related to a kind of casting sandbox.
Background technology
Model casting is also known as " lost-wax casting ", typically refer to and make apperance at fusible material, make shell at apperance Surface coating some layers of refractory material, then shell is discharged in apperance fusing, thus the casting mold obtained without die joint, after high-temperature roasting, get final product the founding method of back-up sand cast.Because apperance extensively adopts wax material to manufacture, therefore often model casting is called " lost-wax casting ".The alloy species that available investment casting is produced has carbon steel, steel alloy, heat-resisting alloy, stainless steel, Precise Alloy, permanent-magnet alloy, bearing metal, copper alloy, aluminium alloy, titanium alloy and spheroidal graphite cast-iron etc.The general all more complicated of shape of investment-casting, on foundry goods, the castable minimum diameter portalled can reach 0.5mm, and the minimum wall thickness (MINI W.) of foundry goods is 0.3mm.Aborning can by some originally by the parts of several part combination, by changing the structure of part, design becomes one-piece parts and is directly cast out by model casting, to save the consumption of machining period and metal material, makes design of part more reasonable.
In actual production, need first the fire sand in casting sandbox to be dug out, again fire-resistant sand is backfilled to the height of shell casting gate after putting into shell, then with there being bamboo pole that jam-pack plug around shell is real, cast again, after having cast, first fire-resistant sand is passed through manually to root out, by driving or other lifting means, shell is moved to ground again, first, owing to burying the casting sandbox of shell lower than ground, so heavy fire sand is dug out in the casting sandbox in sand pit, need to expend sizable muscle power and produce a large amount of dust, secondly, after the liquid metals casting of thousands of degree high temperature, meeting and shell produce reaction and generate CO, CO2, sulfur dioxide, the pernicious gases such as toluene, these pernicious gases can only shed in the outlet above casting sandbox, when staff carries out quartz sand to dig out in sandbox, accelerate distributing and there is a large amount of dust of pernicious gas, grievous injury staff is healthy, even if first leave standstill after machining, but due to the limited area that sheds, make exhaust effect also still limited, then, staff is adopt bamboo pole to disclose real having buried shell, when running into some baroque foundry goods, will run into cannot compacting or broken by shell and cause metal liquid to leak outside or foundry goods is scrapped.
