Description

A kind of rear overhang puts the lower half arenaceous shell mould 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 Kind rear overhang puts support lower 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 faying face using die joint as boundary as built-up pattern mostly, 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 among the sand in sandbox, then produce Pouring channel and rising head just complete the sand mold before casting and made;3rd, after sand mold to be carried out to 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, takes out casting, is 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 for the blank for causing to cast out is not known;Operation labor be present in the characteristics of due to process above, its casting method Momentum is big, high to the skilled operation skill set requirements of worker, 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, and reserved processing capacity is big, waste of raw materials, flexible type, the defects such as qualified yield rate is low.
The content of the invention
Above mentioned problem existing for stent blank production 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 puts support and is divided into two parts up and down, separately designs manufacture rear overhang and puts support precoated sand top half arenaceous shell mould Support lower part arenaceous shell mould is put with rear overhang;The 2nd, precoated sand mould that rear overhang is put to 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.
