Abstract
The invention relates to the technical field of casting, in particular to a V-method casting process. The V-method casting process comprises the following steps: step 1, performing film lamination on a model, that is to say, covering a template with a plastic film under the action of vacuumization; step 2, brushing the film-laminated template with a coating; step 3, putting a sand box on the template, wherein added sand is higher than the sand box; step 4, putting the sand box filled with the sand on a vibration compaction table together with the template, and performing vibration compaction; step 5, after vibration compaction, covering the sand box with a layer of plastic film; step 6, performing core setting, box closing, vacuumization and casting. According to the V-method casting process, a process route is reasonable in design, a produced casting is high in surface smoothness and size precision, a production process is simple, the metal utilization rate is high, all old sand is basically recycled, and the modeling cost is reduced.
Description
Technical field
The present invention relates to technical field of forging, be specifically related to a kind of V method casting technique.
Background technology
The casting of V method and lost foam casting also known as negative pressure casting, because getting English Vacuum(vacuum) prefix " V " of a word and gaining the name.It is different from traditional sand, and to cast maximum advantage be do not use adhesive, the casting of V method utilizes plastic sheeting to seal sandbox, by air in vacuum-pumping system extraction type, pressure differential is had inside and outside casting mold, make dry sand closely knit, form required die cavity, vacuumize make casting solidification through lower core, mould assembling, cast, remove negative pressure, molding sand is thereupon defeated and dispersed and obtain foundry goods.But in prior art, technical flow design is coarse, cause the sealing of V method casting mold and intensity all undesirable.
Summary of the invention
For solving the above-mentioned problems in the prior art, the invention provides a kind of V method casting technique.
Technique effect of the present invention is achieved through the following technical solutions:
A kind of V method casting technique, comprises the following steps:
Step one: model overlay film, is overlying in template by plastic sheeting under the effect vacuumized;
Step 2: swabbing in the template after overlay film;
Step 3: be placed on by sandbox in template, adds sand height higher than sandbox;
Step 4: the sandbox filling sand is put on plain bumper together with template and carries out jolt ramming;
Step 5: after jolt ramming, same above sandbox, lid layer plastic sheeting;
Step 6: lower core, mould assembling, vacuumize rear casting.
The invention has the beneficial effects as follows:
A kind of V method casting technique disclosed in this invention, Process Route Planning is reasonable, and surface finish of casting and the dimensional accuracy of production are high, and production process is simple, and using rate of metal is high, the basic fully recovering of old sand, and moulding cost reduces.
Detailed description of the invention
The present invention is realized by following detailed description of the invention:
A kind of V method casting technique, comprises the following steps:
Step one: model overlay film, is overlying in template by plastic sheeting under the effect vacuumized;
Step 2: swabbing in the template after overlay film;
Step 3: be placed on by sandbox in template, adds sand height higher than sandbox;
Step 4: the sandbox filling sand is put on plain bumper together with template and carries out jolt ramming;
Step 5: after jolt ramming, same above sandbox, lid layer plastic sheeting;
Step 6: lower core, mould assembling, vacuumize rear casting.
Last it is noted that the foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, although with reference to previous embodiment to invention has been detailed description, for a person skilled in the art, it still can be modified to the technical scheme described in foregoing embodiments, or carries out equivalent replacement to wherein portion of techniques feature.Within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
