Description

A kind of rear overhang puts mould under the first half arenaceous shell of support
Technical field
The invention belongs to vehicle production field, more particularly to a kind of rear overhang puts one in the blank manufacture method of support Plant the lower mould that rear overhang puts support first half arenaceous shell mould.
Background technology
Rear overhang puts support and is provided in the part that automobile axle is used to carry damper and suspension arrangement, due to Structure and shape matching are complicated, and its producer using the method production blank of metal casting, is then being machined mostly, To obtain more preferable stability and machining accuracy;Existing rear overhang is put support and cast mostly using cast iron, and it is cast The method of making is to put support Design drawing according to rear overhang first, selects suitable die joint, makes profile and is put with rear overhang Support shape identical built-up pattern, this built-up pattern mostly by boundary of die joint as built-up pattern faying face, this Kind of model is mostly wooden or aluminum is to carry and to process;Second, model is put into sandbox, foundry sand is inserted and rams It is real, sandbox is separated into taking-up model, shape and model identical cavity are formed in the middle of the sand in sandbox, then produce Pouring channel and rising head just complete the sand mold before casting and made;3rd, sand mold is carried out after appropriate drying, sandbox is closed Hold together, casting molten metal is poured into from pouring channel;4th, sandbox is removed after cooling, sand mold is crushed, casting is taken out, taken out Cast gate and rising head, just complete the making that rear overhang puts stent blank;When being poured into due to molten iron in sand mold, molten iron is deposited to sand mold In expansive force, and sand mold is relatively soft, will cause sand mold inner chamber shape produce change, and it is this change be it is uncertain, just The appearance and size of the blank cast out is caused not know;There is operative's labor in the characteristics of due to process above, its casting method Momentum is big, high to the skilled operation skill set requirements of workman, it is desirable to which working area is big, and operating environment is poor, and dust is big, cast(ing) surface material Roughness value is high, reserves processing capacity greatly, waste of raw materials, flexible type, the qualified low defect of yield rate.
The content of the invention
The above mentioned problem that stent blank production is present is put for existing rear overhang, the present invention proposes that a kind of rear overhang is put The blank manufacture method of support, it is characterised in that:Comprise the following steps:First, the design drawing of support is put according to rear overhang, will Rear overhang put support be divided into above and below two parts, separately design manufacture rear overhang put support precoated sand top half arenaceous shell mould Support bottom sub-sand shell mould is put with rear overhang;2nd, the precoated sand mould that rear overhang is put into support is put into automatic moulding machine On produce precoated sand cast arenaceous shell model;3rd, rear overhang is put into support top half arenaceous shell mold box rear overhang and puts branch Frame the latter half arenaceous shell mold clamp and fixation;4th, the metal liquid of pouring molten in support arenaceous shell mould is put in rear overhang; 5th, take out casting and clear up.
