Embodiment 1

[0021] This embodiment mainly describes: in investment casting, the molding technology of making the thick and large part of the part into a hollow wax mold. The application of this technology can well solve the problem of casting fillet sinking in thick and large parts of castings, and increase the rapid cooling speed of casting thick and large parts and hot joint concentrated parts, thereby improving production efficiency and helping to prevent casting deformation.

[0022] In the wax model body 1 in Fig. 1, due to the fact that under a certain precision, the contrast size of the relatively thick part 2 is too large, after the wax mold is injected, the concave rounded corners near the thick part are prone to produce Phenomena in the depression zone 3. For some investment castings with special requirements, there are not only unreasonable design problems at the rounded corners of such castings, but also the requirement that the rounded corners are not allowed to have shrinkag...

Abstract

The invention discloses a manufacturing method of a hollow wax pattern, which is a technical process to produce thick segments of applied components into hollow wax patterns during the process of manufacturing machine-pressed wax pattern. By adopting the method, defects caused by blind spots of the design of thick large sections of forgings can be effectively resolved, anti-deformation technology with extensive experiences, repairing technique of brushing thin layer of liquid wax and liquid wax filling technique can be omitted, and the contrast of different dimension of small cast blocks can be reduced, which can not only create conditions for developing computer digital control dies technology, but also save labor, time and waxes. The main technologies utilized by the invention is that: hot spots or thick large sections of wax pattern are made into wax pattern bodies with a cavity, and the cavity openings anastomose and is attached with a cavity-riser neck or an end cover, and then bonded and closely sealed by hot wax liquid, and a hollow wax pattern is formed after eliminating marks.

Description

technical field [0001] The invention relates to a method for making a hollow wax model, and is especially suitable as an auxiliary method for designing machine-injected wax models. Background technique [0002] At present, in the wax pattern production process of investment casting precision casting, although there are liquid injection, paste injection, solid injection and computer numerical control automatic wax injection technology, but due to the problem of wax mold shrinkage and The rheological behavior of the mold material, so the CT1-CT16 precision standard is specified in the national ministry standard casting dimensional tolerance of GB / T6414-1999, and the CTG1-CTG8 is specified in the ISO / CD8082-2 international industry standard casting dimensional tolerance However, in practical applications, due to the large contrast in shape and size of some parts, they belong to the low level of casting dimensional tolerance regulations, and even exceed these specified ranges, b...
