Abstract
The invention discloses a fabrication method of a valve mold shell. The fabrication method comprises the following steps: stirring prepared paraffin wax in a wax stirrer, pouring the mixed paraffin wax slurry into a wax injector, carrying out injection molding to form a wax mold by the wax injector, shaping the molded wax mold, mixing slurry, aluminum chloride and ammonium chloride in a glue stirrer, rolling the shaped wax mold in the mixed slurry, carrying out sand showering treatment on the slurry coated wax mold by a sand shower, showering a sand layer with the thickness of 5-10mm on the surface of the wax mold after sand showering treatment, airing the mold shell after sand showering, placing the mold shell into a roasting furnace for roasting at high temperature, and forming the mold shell through high-temperature roasting. According to the fabrication method, the strength of the mold shell can be improved, and the mold is not deformed after demolding and the like.
Description
Technical field
The present invention is a kind of investment casting shell, particularly relates to a kind of preparation method of valve shell, is applied to casting field.
Background technology
In traditional process for making shell, easily occur insufficient strength, the shortcomings such as permeability difference, some intensity reaches, and does not but have good gas permeability, some good permeabilities, and intensity does not but reach, and causes the housing produced not reach requirement.
Summary of the invention
For above-mentioned technical problem, the invention provides a kind of preparation method with the valve shell increasing form strength
.
Technical problem solved by the invention realizes by the following technical solutions: a kind of preparation method of valve shell, its preparation process is: be placed on to stir in wax machine by the paraffin got and stir, wax slurry after stirring is placed in wax injector, wax-pattern is injection molded into by wax injector, type process is repaiied to the wax-pattern of injection formed, slurry and aluminium chloride and ammonium chloride are together placed on to stir in glue machine and stir, wax-pattern after fixing is rolled on the slurry be stirred, the process of pouring sand is carried out by drenching sand machine by being painted with the wax-pattern after slurry, after filtering sand process, wax-pattern surface is spooned the thick sand removal layer of 5-10 millimeter, after air-dry for the formwork after pouring sand, be placed on roaster and carry out high-temperature roasting, formwork is roasted by high temperature
detailed description of the invention
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with specific embodiment, setting forth the present invention further.
Be 50 kilograms to get quartz sand, rice husk is that the present invention will be described further for how many double centners:
By the Ludox got, put into mixer to stir, then the wax-pattern wrapping slurry being wrapped again thickness is 1 millimeter of Ludox, quartz sand 50 kilograms is constantly sprinkled into by the wax-pattern wrapping up in Ludox, with rice husk double centner, until after wax-pattern surface wraps the quartz sand of 2 mm of thickness, rice husk, be placed on and carry out in ventilation air-dry, air-dry rear roasting stove of directly putting into carries out roasting.
Last it is noted that above embodiment only in order to illustrate the present invention and and unrestricted technical scheme described in the invention; Therefore, although this description with reference to each above-mentioned embodiment to present invention has been detailed description, those of ordinary skill in the art should be appreciated that and still can modify to the present invention or equivalent to replace; And all do not depart from technical scheme and the improvement thereof of the spirit and scope of the present invention, it all should be encompassed in right of the present invention.
