Description
Technical field
The present invention relates to the moulding system that a kind of static pressure double, double cross are changed trains, belong to machine casting field.
Background technology
At present, in Foundry Production, because sand casting production efficiency is high, cost is low, flexibility is large, adapt to wide, technology maturation, be most widely used both at home and abroad.Formative method for sand casting has hand moulding and machine molding, and modern machines moulding productivity ratio is high, steady quality, and labor strength is low, has many unrivaled advantages compared with hand moulding.Machine molding in application has ram-jolt, microseism squeeze mo(u)lding at present; Low middle pressure, high pressure moulding; The moulding of static pressure consolidation; Gas punching, air-flow gain add extrusion moduling etc., respectively have pluses and minuses and accommodation.
High pressure moulding is a kind of formative method that carries out compacting tight sand under high specific pressure.Specific pressure refers to that, in the time of compacting tight sand, the size of pressure intensity on molding sand surface, acts on the power in molding sand per surface area, and the unit of specific pressure is kilograms per centimeter.Obviously, specific pressure is high, and sand mold is also high by the degree of consolidation.Specific pressure reaches many height and is called high pressure moulding actually, and different country, data with different formulation difference, roughly have following two classes: all can be described as high pressure moulding.For example, pneumatic microseism moulding, injection molding etc. (compacting ratio forces down 7 kilograms per centimeter).
The advantage of high pressure moulding can be summarized as following some:
1) accurately (can reach 5-7 level) of casting dimension, any surface finish, presentation quality is good.The precision level of high pressure moulding method and shell moulded casting and permanent mold casting are up to the standard equally matched, and cost is but than greatly cheap.
2) the weight uniformity of foundry goods, wall thickness can attenuate, has alleviated casting weight, has reduced machine-finish allowance, saves metal material and machining man-hour, has so just reduced cost of parts.According to statistics, compared with common jolt-squeeze type moulding, casting weight can alleviate 3～7%, and the deviation of weight of steel-casting drops to 1～2% from 3-5%, and ironcasting deviation of weight is reduced to scholar 1% by soil 1.5%.
3) because high pressure moulding method technique is simple, be easy to realize mechanization and automation, compacting operation is extremely short, thereby productivity ratio is very high.Adopt the factory of high pressure moulding technique, generally make increasingly automated or mechanical production line more, the known high-pressure molding machine productivity ratio having can reach 720 casees/hour.
4) alleviate labor strength, improve working conditions, substantially eliminated the adverse effect of old-fashioned jarring formula moulding machine to factory building.For simple foundry goods, adopt the moulding of simple high pressure compression method, can accomplish noiselessness.But, to complex-shaped foundry goods, as adopting pneumatic microseism compacting, noise still has to be solved.
5), compared with general low pressure moulding, high-pressure process can be applied to the larger and complex-shaped foundry goods of size.
General high pressure moulding moulding machine is that single station, single cross are changed trains, the high-pressure molding machine that now also has some doubles, single cross to change trains in addition.Such moulding machine inefficiency, makes the casting mold degree of packing low and inhomogeneous, and dimensional accuracy cannot guarantee, labour intensity is high, and productivity ratio is low.
