Embodiment Construction

[0020] Referring to the accompanying drawings: the schematic diagram of the ice core mold structure: core mold 1; sealing strip 2; sealing plug 3; drainage conduit 4, a precision casting ice core molding process, followed by the following steps:

[0021] 1. A method of using ice cores in precision casting, characterized in that:

[0022] (1) Make ice cores of the required size and shape by using a special mold to condense water;

[0023] (2) Take the obtained ice core out of the mold and put it in a cryogenic environment for future use;

[0024] (3) When making the mold, put the ice core into the mold, inject wax, cool and melt the core, and obtain the wax mold;

[0025] (4) During the process of wax injection, fast filling can be realized by adjusting the temperature and pressure of wax injection;

[0026] (5) Various shell coating processes are used: after obtaining the mold shell and coating, the hollow cavity of fixed shape and size copied from the wax mold obtained by m...

Abstract

The invention discloses a precision casting mould making technology by using an ice core. The technology is as follows: firstly, manufacturing an ice core with a required size and shape by a method using a specific mould to condense water; secondly, taking out the obtained ice core from the mould, and putting the ice core into an appointed environment to store for later use; during mould making, installing the ice core into the mould, injecting wax, cooling, and fusing a mold core to obtain a wax mould, wherein, during wax injecting, the wax injecting temperature and pressure are regulated to realize rapid mold filling, so that surface cold shut caused by chilling can be avoided and size deviation caused by mold core fusing can be reduced; and finally, casting an obtained mould casing by using different casing coating technologies. By using the technology disclosed by the invention, the environmental pollution is eliminated, the production cycle is shortened, the resource waste is avoided, the on-site work environment is improved, the problems caused by chilling and mold core fusion are solved, and the stability of cast quality is enhanced.

Description

technical field [0001] The invention mainly relates to the field of precision casting, in particular to a method for precise use of ice core molding. Background technique [0002] Existing methods for forming the inner cavity of precision casting wax molds include: metal mold core pulling (block core pulling and insert core pulling), Huff mold, urea core, water-soluble wax core, etc. Ice core molding is still widely used in the precision casting field. belongs to blank. Contents of the invention [0003] The purpose of the present invention is to make up for the defects of the prior art, to use ice cores instead of urea cores and water-soluble wax to make wax models, and to solve the problems of ice core preservation and wax model surface quality problems. [0004] This method makes up for the technical gap, and at the same time eliminates environmental pollution, avoids waste of resources, improves the working environment on site, solves the problem of wax saponification...
