Abstract
The invention relates to an anti-deformation process method of a massive plate casted by a lost mold, which comprises the following steps: firstly, reducing the deformation of a mold: reducing the self deformation of the mold by adopting a double-sided clamping method when the plastic mold of the massive plate is coated with coatings; secondly, mold boxing: boxing after the coatings of the mold are dried, respectively arranging standard abutment poles in a same plane at the upper part and the lower part in a box and arranging a plurality of single poles which are vertical and are arranged in the plane to form an abutment plate with a space structure; thirdly, sand filling: respectively filling sand on two sides of the mold after the coated mold is close to the abutment plate, simultaneously compacting at different stages, removing the abutment plate after the sand position is filled and carrying out shot-term slight vibration; and fourthly, pouring: placing a pouring basin at the closed top to pour. The method can prevent the deformation lost mold castings, in particular to massive plate castings.
Description
Technical field
The present invention relates to the distortion-free method of a kind of disappearance casting massive plate.
Background technology
Lost foam casting claims vacuum full mold casting again, be that the model that foamed plastics is made is imbedded moulding in the dry sand of binder free, adopt microseism to add the negative pressure consolidation, do not having fuse even do not having to pour into liquid metal under the situation of rising head, holding certain negative pressure in casting and the continuation of insurance of process of setting relaying and make the foamed plastics gasification be replaced a kind of novel casting method of formation foundry goods then by metal.
Disappearance die casting surface quality is good, size is accurate and corner angle are clearly demarcated, use at present with more and more wider at home the obtaining of its these unique advantages, no matter be that cast iron, cast steel or non-ferrous alloy casting have all been realized batch process, but also there are some problems when being applied to the foundry goods of the special or weight super large of some structures in lost foam casting.For the massive plate foundry goods, structure seems simply, but is very easy to deform during with lost foam casting, even when the first-class coating of foam mould (grey product stage) control the distortion of the white mould of plastics, but when group case ram-jolt, still can deform, cause being out of shape behind the casting pouring and scrap
Summary of the invention
The present invention will provide a kind of anti-deformation process method of massive plate casted by lost mold, and this method can prevent that casting deformation from taking place.
For achieving the above object, technical scheme of the present invention is: a kind of anti-deformation process method of massive plate casted by lost mold, and concrete steps are:
1. reduce white moding shape
When the white mould swabbing of massive plate plastics, adopt two-sided clip to enforce the law and reduce white calligraphy or painting model body distortion;
2. white module case
Organize case after the white mould coating oven dry, upper and lower position at first respectively is provided with a standard rod in same plane in case, and the rod single face is provided with several vertical and be the single pole of a horizontal layout, forms the backup plate of a space structure;
3. back-up sand
The white mould of having brushed coating is close to the backup plate back-up sand respectively sequentially on the Bai Mo two sides afterwards, and ram-jolt stage by stage simultaneously removes backup plate after the sand position is filled up, and carries out the short time microseism again;
4. cast
Bind and put pouring basin and pour into a mould.
The invention has the beneficial effects as follows: this method can prevent to disappear distortion, especially the massive plate foundry goods of die casting.
Description of drawings
Fig. 1 is an of the present invention group of case schematic diagram.
The specific embodiment
The present invention is further illustrated below in conjunction with accompanying drawing and embodiment.
Anti-deformation process method of massive plate casted by lost mold of the present invention:
As shown in Figure 1, when white mould 2 swabbings of massive plate plastics, adopt two-sided clip to enforce the law as far as possible white mould 2 distortion itself is reduced to Min., carry out sandbox group case 3 after the oven dry of Bai Mo 2 coating.Upper and lower position at first respectively is provided with a standard rod 6 in same plane in sandbox group case 3, single pole rod 1 single face is provided with several vertical and be the single pole of a horizontal layout, form the backup plate of a space structure, the white mould of having brushed coating is close to the backup plate back-up sand respectively sequentially on the Bai Mo two sides afterwards, ram-jolt stage by stage simultaneously, remove backup plate after the sand position is filled up, carry out the short time microseism again, can bind and put pouring basin 5 and pour into a mould.
Claims (1)
1. anti-deformation process method of massive plate casted by lost mold, it is characterized in that: concrete steps are:

(2) white module case
Organize case after the white mould coating oven dry, upper and lower position at first respectively is provided with a standard rod in same plane in case, and the rod single face is provided with several vertical and be the single pole of a horizontal layout, forms the backup plate of a space structure;
(3) back-up sand
The white mould of having brushed coating is close to the backup plate back-up sand respectively sequentially on the Bai Mo two sides afterwards, and ram-jolt stage by stage simultaneously removes backup plate after the sand position is filled up, and carries out the short time microseism again;
(4) cast
Bind and put pouring basin and pour into a mould.
