Abstract
The invention discloses a method for manufacturing patching wax used for precision casting wax mould, which is characterized in that the patching wax is manufactured by mixing and heating the following raw materials by weight percent: 50-70% of white vaseline and 30-50% of wax. By the method, not only the patching wax can effectively patch the rough flaws on the wax mould but also the rigidity of the patching wax can be adjusted according to the requirements; the patching wax is good in use effects and simultaneously low in price, and can reduce the production cost. Through detection, the casting cast by the wax mould patched by the patching wax manufactured by the invention has the roughness up to Ra 0.4-3.2mu m.
Description
Technical field
The present invention relates to a kind of preparation method of repairing wax, especially for the preparation method of repairing hot investment casting wax-pattern blemish or being used to assemble a kind of patching wax used for precision casting wax mould that the wax-pattern facing uses.
Technical background
Along with the progress of society, precision casting has been widely applied to aviation, weapons department at interior all industrial departments, particularly electronics, oil, chemical industry, communications and transportation, light industry, weaving, pharmacy, medicine equipment, pump and valve member.Precision-investment casting is a kind of casting technique of cutting less or not having cutting, and casting dimension accuracy height, the surface roughness of producing is low, flexibility is high, adaptability is strong, and special in the complex-shaped parts of foundry goods, the superiority of this casting is more remarkable.In the precision-investment casting process, the manufacturing of wax-pattern is an important step, and the surface quality of wax-pattern is determining the surface quality of foundry goods.The long-term use of Wax mold inevitably can cause die surface coarse, thereby causes the rough surface of wax-pattern, and wax-pattern also can cause the surface to collide with in circular flow.Therefore the wax-pattern rough surface is a kind of common defective.At this defective, in most cases the wax-pattern blemish is not repaired at present, but water by the time outpour foundry goods after, for reach instructions for use adopt to casting surface defect weld, the method for reconditioning, this method has not only increased the cost of foundry goods, and has prolonged the duration.The rough surface to wax-pattern that also has is repaired, and present method for repairing and mending is: adopt and repair from the repairing wax of external import, the deficiency of the repairing wax of this external import is: the one, and this repairing wax hardness is excessive, and result of use is bad; The 2nd, its hardness is difficult for regulating; The 3rd, cost an arm and a leg, improved production cost.
Summary of the invention
The object of the present invention is to provide and a kind ofly can repair hot investment casting wax-pattern blemish or wax-pattern assembling facing, can reduce production costs again, repair that cured hardness is convenient to regulate, the preparation method of a kind of patching wax used for precision casting wax mould easy to use.
For reaching above purpose, the technical solution adopted in the present invention is: the preparation method of this a kind of patching wax used for precision casting wax mould, it is characterized in that it is to be made by following raw materials by weight percent: albolene accounts for 50-70%, and wax accounts for 30-50%, makes through Hybrid Heating.
The preparation method of described patching wax used for precision casting wax mould, its procedure of processing is:
(1), the percentage of determining albolene and wax according to the purposes and the hardness of required repairing wax, the shared percentage of albolene is big more, the repairing wax hardness that is made into is soft more, the shared more for a short time repairing wax hardness that is made into of percentage of albolene is hard more, the repairing that obtains required different hardness by the proportioning ratio that changes albolene and wax is cured, then by the percentage weighing albolene of determining and the consumption of wax.
(2), Hybrid Heating preparation: adopt the stainless steel heating container, during preparation, put into albolene earlier, put into wax again, heat then, the stainless steel heating container is uncovered in heating process, be beneficial to the water vapour evaporation in the mixing of albolene and wax, simultaneously, in heating process, will stir, too high with the mixture local temperature that prevents albolene and wax, phenomenon occurs burning, the mixture of albolene and wax all becomes liquid state by the time, and after having water vapour to produce, need to continue heating 10-12 hour, treat to use after the mixture cooling of albolene and wax.The general softer repairing wax of hardness is used to assemble facing, and the higher relatively repairing wax of hardness is used to repair the wax-pattern surface;
Albolene of the present invention is the oil product of ointment shape, is important daily-use chemical industry, medicine, fine chemistry industry raw materials for production; Described wax is the hot investment casting wax identical with the wax material of the wax-pattern that will repair.
Beneficial effect of the present invention is: with the repairing wax phase ratio of external import, can not only repair effectively the coarse defective of wax-pattern, and the hardness of repairing wax can adjust as required, result of use is good, and is simultaneously cheap, can reduce production costs.The wax-pattern that the repairing wax that adopts the present invention to make is repaired, the foundry goods that casts out, after testing, the roughness of repairing the position foundry goods with the repairing wax of the present invention's making has reached Ra 0.4--3.2 μ m.
The specific embodiment
Embodiment 1
With albolene 5kg, wax 5kg, successively put into the stainless steel heating container, the stainless steel heating container is uncovered, heats, in the heating process, that does not stop stirs with wooden stick, after looking albolene and wax and becoming liquefied mixture, continue heating 12 hours again, stop heating then, by the time after the cooling, be used to repair elbow wax-pattern surface.Water the elbow cast(ing) surface matter that outpours and reach user's instructions for use.
Embodiment 2
Albolene 6kg, wax 4kg are successively put into the stainless steel heating container, the stainless steel heating container is uncovered, heat, in the heating process, that does not stop stirs with wooden stick, after looking albolene and wax and becoming liquefied mixture, continue heating 11 hours again, stop heating then, by the time be used to assemble threeway wax-pattern facing after the cooling and repair threeway wax-pattern surface, water the threeway foundry goods facing that outpours and assemble good seamless surface quality and reach user's instructions for use.
Embodiment 3
With albolene 7kg, wax 3kg, successively put into the stainless steel heating container, the stainless steel heating container is uncovered, heats, in the heating process, that does not stop stirs with wooden stick, after looking albolene and wax and becoming liquefied mixture, continue heating 10 hours again, stop heating then, by the time be used to repair impeller wax-pattern surface after the cooling, water the impeller casting surface quality that outpours and reach user's instructions for use.
