Appliance for detecting metal casting evanescent mode

Abstract

The invention discloses an appliance for detecting a metal casting evanescent mode, belonging to the technical field of devices for detecting the metal casting evanescent mode and being used for checking and detecting the metal casting evanescent mode. According to the technical scheme, the device comprises an iron plate plane frame tool and an iron plate plane support tool, wherein the iron plate plane frame tool and the iron plate plane support tool are made by plane iron plates, an internal detection hole is formed in the center of the iron plate plane frame tool, the shape of the periphery of the inner wall of the internal detection hole is matched with the shape of the periphery of the end face of the evanescent mode, and the shape of the periphery of the plane of the iron plate plane support tool is matched with the shape of the periphery of the inner wall of the end face of the evanescent mode. The appliance is capable of rapidly and accurately detecting and finding the quality and deformation degree of the upper end face and the lower end face of the box body type casting evanescent mode during casting production, and providing accurate quality information and basis for correction of deviation of the evanescent mode before casting, improvement of the casting quality and efficiency, and reduction of the product cost. The appliance has the advantages of accurate and reliable detection result, capability of increasing the labor efficiency, low repeated utilization rate, simplicity in operation, and wide application range, and is easy to store.

Description

technical field [0001] The invention relates to an instrument for detecting the deformation and quality of lost foam of metal castings, and belongs to the technical field of detection devices for lost foam of metal castings. Background technique [0002] Lost foam casting is a general metal casting process. In the production of lost foam casting, the lost foam model needs to be prefabricated, and the lost foam made of polystyrene (EPS) pre-expanded by beads and pressed at high temperature by steam will be affected by the temperature of the external environment. , Humidity changes and easily deformed, which seriously affects the quality of casting products, especially the quality of the upper and lower end faces of box-type castings directly affects the processing, assembly, installation and use of castings. Therefore, in foundry production, the lost foam needs to be strictly inspected before coating or when the bonding process is completed. At present, most of the known los...

AI Technical Summary

Problems solved by technology

At present, most of the known lost foam inspections use the visual method, weighing method and physical dimension measurement method. It is single and cannot comprehensively, comprehensively and accurately reflect the real quality problems of lost foam castings. At the same time, the above inspection methods are inconvenient to operate and are not suitable for large-scale and multi-batch lost foam casting production.
