This utility model discloses an adjustable shaft holder for cast steel molding, including a shaft base and a shaft. A cross groove is provided on the top surface of the shaft base, and bolt holes are spaced apart within the cross groove. A bushing is bolted above the bolt holes, and a shaft groove is provided inside the bushing, with the shaft itself housed within the groove. This utility model, by providing multiple bolt holes within the cross groove, allows for flexible adjustment of the shaft's center distance according to production needs, meeting the production requirements of castings of different sizes. It enables 2-hole and 4-hole shaft holders to share a single base, improving the device's versatility and production adaptability, significantly reducing the number of shaft holders required and storage space needed, and greatly lowering production costs.

The invention provides a sample tube verification device and method for ferrite furnace tube oxide skin accumulation detection, belongs to the technical field of nondestructive detection equipment, and can at least partially solve the problem that the application of an existing magnetic detection method on a ferrite furnace tube lacks reliable detection reference. In order to solve the problems of high radiation risk, low detection efficiency, high requirement on detection space and easy missing detection in the prior art in the prior art, the invention provides a sample tube, and the sample tube is provided with a filling unit, an isolation assembly and a closing assembly. The simulation medium can form a plurality of mutually distinguished accumulation states in the sample tube, so that the simulation of different accumulation working conditions of the oxide skin in the ferrite furnace tube is realized under the condition of not repeatedly preparing a plurality of sample tubes, and the preparation number and the use cost of the verification sample tube are reduced.

The application discloses an automatic coordination mold core combined mold, which comprises a pair of opposed upper mold plates (1) and lower mold plates (2), the upper mold plates and the lower mold plates are each provided with more than one through hole (3), the through holes (3) of the upper mold plates and the lower mold plates are aligned in pairs, upper mold cores (4) and lower mold cores (5) are correspondingly arranged in the through holes (3) of the upper mold plates and the lower mold plates, the upper mold cores (4) are connected with the inner walls of the through holes (3) of the upper mold plates (1) through circumferentially distributed elastic components (6), the lower mold cores (5) are also connected with the inner walls of the through holes (3) of the lower mold plates (2) through circumferentially distributed elastic components (6), and the upper mold cores and the lower mold cores in the through holes (3) aligned in pairs are closed to form a cavity. The application can effectively reduce the mold development cost and is very suitable for the characteristics of multiple specifications and small quantity of aviation rubber and plastic sealing elements.
