Abstract
The invention discloses a repairing method for assembly and splicing of split wax molds in the investment casting process, which comprises the steps as follows: premelting liquid wax (2); after splicing the wax molds, drawing the liquid wax (2) with a rubber head dropper (1) to drop at a binding part; rotating the wax molds to allow the liquid wax to flow along a binding surface; and allowing the liquid wax (2) to permeate into a splicing part gap (3) when the liquid wax (2) encounters the splicing part gap (3), so as to be filled in the splicing part gap (3). The repairing method is simple in operation and practical, and can be used for repairing the wax molds with narrower inner cavities. For casts in complicated structures, split molds can be used for manufacturing the wax molds, so that the mold making cost can be lowered.
Description
Technical field
The invention belongs to the model casting technical field, particularly the combined and spliced method for repairing and mending of split wax-pattern.
Background technology
In investment casting process, the combined and spliced mode of split wax-pattern is used comparatively general, promptly plural split wax-pattern; Become whole wax-pattern after the splicing, in the actual production process, owing to self shrinking of each split wax-pattern; And the deviation of mould manufacturing existence; Binding site shape and theoretical shape there are differences, and during the splicing wax-pattern, more or less have certain slit at the binding site faying face; Some wax-patterns are repaired because of " slit " inconvenience and are scrapped, and " slit " when some foundry goods splice because of wax-pattern do not repaired and caused foundry goods to have " slit " to scrap.To " slit ", the wax-pattern crack of splicing wax-pattern, at present, method with the most use is brushing or smears slack wax; But for the narrower wax-pattern of inner chamber, this method is awkward maybe and can't operates, simultaneously; Because the adhesion between slack wax and the wax-pattern is little; In the subsequent operation process, be prone to cause and split, finally cause foundry goods that " slit " arranged.
Summary of the invention
For solving the problem that exists in the prior art, the invention provides the combined and spliced method for repairing and mending of split wax-pattern in a kind of investment casting process, can be easily to the split wax-pattern slit after combined and spliced repair.
Technical scheme of the present invention is described below:
The combined and spliced method for repairing and mending of split wax-pattern has melted liquid wax in advance in a kind of investment casting process, after the wax-pattern splicing; Draw liquid wax with glue head dropper and drop in binding site; Rotate wax-pattern, liquid wax is flowed, when liquid wax runs into the slit, stitching section along faying face; Infiltrate in the slit, stitching section, thereby fill the slit, stitching section.
The invention has the beneficial effects as follows: simple to operate, practicality, but the narrower wax-pattern of repairing lumen.
Description of drawings
Fig. 1 is a sketch map of the present invention.
Among the figure: 1-glue head dropper, 2-liquid wax, slit, 3-stitching section.
The specific embodiment
Below in conjunction with accompanying drawing, the present invention is done further explain:
The combined and spliced method for repairing and mending of split wax-pattern has melted liquid wax 2 in advance in a kind of investment casting process, after the wax-pattern splicing; Draw liquid wax 2 with glue head dropper 1 and drop in binding site; Rotate wax-pattern, liquid wax is flowed, when liquid wax 2 runs into slit 3, stitching section along faying face; Infiltrate in the slit, stitching section 3, thereby fill slit, stitching section 3.
The present invention is simple to operate, practicality, but the narrower wax-pattern of repairing lumen.For the complicated foundry goods of structure, adopt the split designing mould to make wax-pattern, can reduce die manufacturing cost.
In addition, the present invention extends in the model casting, the repairing of core (like the urea core), repairing in crack etc. in the wax-pattern.
Claims (1)
1. the combined and spliced method for repairing and mending of split wax-pattern in the investment casting process is characterized in that: melted liquid wax (2) in advance, after the wax-pattern splicing; Draw liquid wax (2) with glue head dropper (1) and drop in binding site; Rotate wax-pattern, liquid wax is flowed, when liquid wax (2) runs into slit, stitching section (3) along faying face; Infiltrate in the slit, stitching section (3), thereby fill slit, stitching section (3).
