Description
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

Embodiment
In order to further illustrate technical scheme, in conjunction with embodiment of the invention is illustrated, such as
Fig. 1 to Fig. 9, puts according to rear overhang in the design drawing of support, this example by taking compact car rear suspension bracket as an example, after automobile
Mounting bracket is divided into upper and lower part using horizontal bar plate as interface, and the appearance and size that rear overhang is put into support amplifies 8-12 millis
Rice, makes rear overhang and puts mould 1 and top on the top arenaceous shell of support first half arenaceous shell mould and lower half arenaceous shell mould respectively
Mould 4 under mould 3 on mould 2 under arenaceous shell, bottom arenaceous shell, bottom arenaceous shell, and rear overhang is respectively prepared puts frame upper arenaceous shell and automobile
Rear suspension bracket bottom arenaceous shell；Rear overhang is put into frame upper arenaceous shell and rear overhang is put the arenaceous shell combination of support bottom and completed
Whole puts contoured cradle identical arenaceous shell with rear overhang；Used in this example per mold while making two rear overhangs puts branch
The arenaceous shell of the upper and lower part of frame；And rear overhang is put into support arenaceous shell mould installion to arenaceous shell automatic moulding machine, produce
Rack shell shape identical arenaceous shell is put with rear overhang；The arenaceous shell that the rear overhang made is put into support is placed on cast field
Ground, the fusing molten iron matched is poured into arenaceous shell, after cooling, opens arenaceous shell, takes out casting, and cast gate and rising head are removed, and
The impurity cleared up on spray, just completes the production of the blank of brake disc.
Due to arenaceous shell production when automated production, can produce in enormous quantities, overcome clay-bonded sand or phenolic sand molding
Complexity, saves a large amount of Foundry quartz sands, reduces production cost and labor intensity；Arenaceous shell die life is long simultaneously, overcomes
Wooden model or the short-life shortcoming of aluminum dipping form.
