New energy waste heat generator suction end body casting process design method

Abstract

The invention discloses a new energy waste heat generator air suction end body casting process design method, which comprises the steps of S1, establishing a three-dimensional solid model of a new energy waste heat generator air suction end body by applying ProE modeling software to obtain a virtual casting mold; S2, performing mold filling and solidification on the virtual casting mold obtained in the step S1 by using numerical solidification simulation software to obtain a virtual casting; S3, analyzing the hot spot position of the virtual casting; and S4, casting an actual new energy wasteheat generator air suction end body casting according to the various parameters of the virtual casting obtained in the step S2, and eliminating the hot spot by designing a riser and a chilling block of the actual casting. According to the new energy waste heat generator air suction end body casting process design method, the hot spot position determination method is optimized, and the hot spot position of casting defects can be accurately predicted. The hot spot is correspondingly treated, and the occurrence probability of shrinkage porosity, shrinkage cavity and air hole conditions of castings in the production process can be reduced.

Description

technical field [0001] The invention relates to the technical field of casting process design, in particular to a casting process design method for a suction end body of a new energy waste heat generator. Background technique [0002] In order to save energy, reduce pollution, and reduce production costs, most enterprises have begun to use waste heat generators to generate electricity from waste heat. The important part of waste heat generators is the suction end body, and its structure is as follows: figure 1 As shown, the structure of the suction end body is relatively complex, the development is difficult, and the production difficulty coefficient is high, resulting in air leakage during the use of the product, reducing the use efficiency of the product and even directly failing to use the product normally. [0003] Casting process design is a key process for making the suction end body, so as to ensure that the produced castings have no defects such as shrinkage porosity...

AI Technical Summary

Problems solved by technology

The existing casting process design and the point model method used to analyze the location of hot joints can only be applied to two-dimensional cross-sections, and usually the manual calculation of the selected cross-section is demanding, the calculation amount is very large and cumbersome, and it is not easy to apply to the computer

After expanding to the three-dimensional situation, because the heat dissipation effect of the surrounding nodes on a certain node cannot be considered, the results obtained by the application are not ideal, and the position of the hot node that is prone to casting defects cannot be accurately predicted
