Abstract
The present invention relates to a kind of casting method of evaporative pattern, especially relate to a kind of preparation method of evaporative pattern running gate system, it is characterized in that: the method designs, makes, assembles, applies, pours into a mould production; The inventive method is unique, can improve casting quality, the rapid Design of running gate system of enhancing productivity, realize, production and making.
Description
Technical field
The present invention relates to a kind of casting method of evaporative pattern, especially relate to a kind of preparation method of evaporative pattern running gate system.
Background technology
Casting moulding system is made up of the part such as cup and pouring basin, sprue, sprue base, Transverse running channel and ingate.At present, in lost foam casting is produced, the general global formation of running gate system, and be solid material.In running gate system, sprue shape is all generally circular or square, and horizontal, ingate shape mostly is square or trapezoidal.In apperance process, circular sprue generally adopts resistance wire to cut, and this processing mode exists following shortcoming: surface quality is coarse, out-of-shape, has faulting of slab ends phenomenon, during cast, small rut place coating can be rushed in foundry goods, causes foundry goods to produce inclusion defect; Square straight, cross gate have angular structures, and apply difficulty, coating layer thickness is uneven, if coating is thinner, easily break during cast by washing away of molten iron, cause foundry goods to produce the defect such as burning into sand, folder coating.
Also do not overcome the method for above-mentioned defect so far.
Summary of the invention
The object of the invention is the defect overcoming prior art, provide a kind of method unique, casting quality can be improved, the rapid Design of running gate system of enhancing productivity, realize, production and making a kind of preparation method of evaporative pattern running gate system.
The present invention realizes in the following way:
A preparation method for evaporative pattern running gate system, is characterized in that: the method comprises the steps:
A, design: be divided into independently unit to make each part of running gate system;
B, making: the method adopting foaming and molding, make each module of running gate system;
C, assembling: assemble with nested form between each cellular construction, evaporative pattern glue special is smeared in nested face;
D, to apply: coating selection lost foam paint, Baume degrees controls in 55 ~ 60 scopes, and flow coat brushes one time for twice;
E, cast are produced;
Described unit is respectively: isometrical running channel, dialectal switching running channel, reducing running channel, elbow, threeway running channel and four-way running channel, and each cellular construction design many kinds of parameters specification is for you to choose;
The frequency of utilization of cellular construction according to different size specification, by the cellular construction typesetting of parameter specification high for frequency of utilization on same foaming mould, the cellular construction typesetting of the parameter specification that frequency of utilization is low on same foaming mould, each mould typesetting 5 ~ 7 cellular constructions;
The thickness of described coating is 1.5mm ~ 2mm;
Described evaporative pattern glue special is that magnificent WPH-1 cold glue is praised in Beijing;
Described coating selection lost foam paint, 40KG barreled paste, namely Shanghai Ou Qu likes HA705, and its density is 1.30-1.50g/cm
3, suspendability (24h)>=98.0%, solids content %46.0-50.0, gas permeability (corrected value) 30 ~ 50.
The present invention has following effect:
1) method unique, substantially reduce the designing and making cycle, improve production efficiency: the integrated poured system of method provided by the invention is assembled by each construction unit and formed, design running gate system sprue, cross gate, ingate cross section when sectional dimension time, can select in the injection system structure unit designed and produced, substantially reduce the designing and making cycle, improve production efficiency.
2) improve casting quality: method provided by the invention adopts the method for foaming and molding, make each module of running gate system, each like this construction unit is hollow structure, in casting process, gas forming amount reduces, avoid carbon defects, molten iron is regurgitated, the defects such as foundry goods gas enclosure hole, thus improve the quality of foundry goods; And inlaid-assembling mode, improve the sealing of each construction unit connecting portion, stopped coating, molding sand enters and connect in gap, thus avoid the inclusion defect of cast-internal; Running gate system respectively forms construction unit and adopts foam forming method to make, and improves running gate system surface quality, and ensure that the stability of size.
Accompanying drawing explanation
Fig. 1 is the assembly drawing of running gate system of the present invention.
