Abstract
The invention relates to a lost foam casting method and in particular relates to a method for manufacturing a lost foam casting system. The method is characterized by comprising the following steps: designing, manufacturing, assembling, coating and casting. The method is unique, the casting quality can be improved, the production efficiency is improved, and rapid design, production and manufacture of the casting system are realized.
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 that pouring basin, sprue, sprue base, Transverse running channel and ingate etc. partly form by cup.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 cutting, 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, apply difficulty, and coating layer thickness is inhomogeneous, if coating is thinner, broken by washing away easily of molten iron, cause foundry goods to produce the defects such as burning into sand, folder coating.
Also do not overcome so far the method for above-mentioned defect.
Summary of the invention
The object of the invention is to overcome the defect of prior art, provide a kind of method unique, can improve casting quality, enhance productivity, realize a kind of preparation method of evaporative pattern running gate system of rapid Design, production and the making of 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: each part of running gate system is divided into independently unit and makes;
B, making: adopt the method for foaming and molding, make each module of running gate system;
C, assembling: between each cellular construction, with nested form, assemble, nested face is smeared evaporative pattern glue special;
D, apply: coating selection lost foam paint, Baume degrees is controlled in 55～60 scopes, twice brushing of flow coat one time;
E, cast are produced;
Described unit is respectively: isometrical running channel, and dialectal switching running channel, reducing running channel, elbow, threeway running channel and four-way running channel, each cellular construction design many kinds of parameters specification is for you to choose;
According to the frequency of utilization of cellular construction described in different size specification, by the cellular construction typesetting of the high parameter specification of 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, 5～7 cellular constructions of each mould typesetting;
The thickness of described coating is 1.5mm～2mm;
Described evaporative pattern glue special is the good magnificent WPH-1 cold glue in Beijing;
Described coating selection lost foam paint, 40KG barreled paste, Shanghai Ou Qu likes HA705, 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, greatly shortened the designing and making cycle, improved production efficiency: the integrated poured system of method provided by the invention is formed by each construction unit assembling, in the cross section of design running gate system sprue, cross gate, ingate when during sectional dimension, can in the injection system structure unit having designed and produced, select, greatly shorten the designing and making cycle, improved 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 construction unit is hollow structure like this, in casting process, gas forming amount reduces, avoided carbon defects, molten iron to regurgitate, the defects such as foundry goods gas enclosure hole, thereby the quality of raising foundry goods; And inlaid-assembling mode, improved the sealing of each construction unit connecting portion, stop coating, molding sand enters and connects in gap, thereby avoided the inclusion defect of foundry goods inside; Running gate system respectively forms construction unit and adopts foam forming method to make, and has improved running gate system surface quality, and has guaranteed the stability of size.
