Description

Technical Field

[0001] The utility model relates to the technical field of nickel-iron water standard sample sampling, in particular to a liquid nickel-iron water standard sample shaping mould. Background Art

[0002] In the process of using nickel-iron water for stainless steel smelting, in order to complete the nickel-iron water analysis task and the future fully automatic laboratory application, large quantities of nickel-iron water standard samples are required for inspection and testing. Currently, there are no such standard samples on the market, and the applicant can only manufacture the standard samples by himself. When the applicant initially manufactured the nickel-iron water standard samples, the existing ordinary sampler was used to shape the nickel-iron water. After shaping, the applicant found that the inside of the molded sample was loose, and it was impossible to use the spark source atomic emission spectrometer to quickly analyze its chemical composition later. After a lot of analysis and research, the applicant found that the main reason for the looseness of the sample was that the material of the existing ordinary sampler dissipated heat slowly and the sample diameter was large. The material of the ordinary sampler dissipated heat slowly, resulting in slow heat dissipation inside the sample; the larger the sample diameter, the slower the heat dissipation inside the sample. The slow heat dissipation inside the sample leads to coarse grains inside the sample, which in turn leads to looseness inside the molded sample. Utility Model Content

After the high-temperature nickel iron water is cooled for a certain period of time, an initial fixed standard sample is formed. In order to increase the cooling speed of the high-temperature nickel iron water in the pouring cavity 11, the inner diameter of the pouring cavity 11 can be minimized while ensuring that the standard sample meets the detection requirements, so as to ensure the compactness of the internal standard sample; the bottom mold gasket 3 is arranged in the bottom mold 2, and the lower part of the upper mold 1 can be inserted into the bottom mold 2 and the bottom mold gasket 3 can realize the The bottom of the pouring cavity 11 is blocked. In practical applications, the bottom mold 2 is placed on the ground, and the bottom mold gasket 3 is placed in the bottom mold 2. After the upper mold 1 is inserted into the bottom mold 2, the bottom mold gasket 3 simultaneously blocks the bottom of the pouring cavity 11. The bottom of the pouring cavity 11 is blocked, thereby ensuring that the liquid molten steel can be cooled and formed in the pouring cavity 11; the upper mold 1 includes a plurality of upper mold assemblies 12, and the plurality of upper mold assemblies 12 can be nested and connected together from top to bottom in sequence. In practical applications, by changing the number of upper mold assemblies 12, the initial standard samples of different lengths can be cast and formed, thereby improving the application flexibility of the utility model. In practical applications, on the basis of facilitating the rapid cooling of the nickel-iron water by controlling the inner diameter of the pouring cavity 11, in order to further improve the heat dissipation speed of the nickel-iron water, the upper mold 1, the bottom mold 2 and the bottom mold gasket 3 can all be made of T1 copper material. The thermal conductivity of T1 copper material is high, thereby improving the heat dissipation efficiency.

At the same time, in order to improve the nesting stability of two adjacent upper mold assemblies 12, the inner diameter of the second plug-in groove 121 is equal to the outer diameter of the first plug-in tube 122; a sub-pouring cavity 123 that passes through from top to bottom is arranged in the middle of each of the upper mold assemblies 12. After a plurality of upper mold assemblies 12 are nested and docked together, a plurality of sub-pouring cavities 123 are docked from top to bottom to form a pouring cavity 11. The inner diameter of the second plug-in groove 121 is larger than the inner diameter of the pouring cavity 11, which facilitates the pouring of nickel iron water on the top of the upper mold 1.

Furthermore, after the nickel-iron water cooling forming, in order to facilitate the smooth opening of the left shaping side mold 125 and the right shaping side mold 126, a left and right opposite mold demolding opening 124 is arranged on the left and right opposite side walls of the left shaping side mold 125 and the right shaping side mold 126. When the bottom mold 2 is separated from the upper mold 1, a crowbar is inserted into the demolding opening 124 to facilitate the opening of the two opposite left shaping side molds 125 and the right shaping side molds 126.

[0026] In actual application, the docking of the left shaping side mold 125 and the right shaping side mold 126 is achieved by inserting the first branch plug-in pipe 1221 at the lower end into the corresponding second branch plug-in slot 1211. Due to the problem of processing accuracy, the left shaping side mold 125 and the right shaping side mold 126 are not tightly docked. In order to improve the tightness of the docking of the left shaping side mold 125 and the right shaping side mold 126, each of the upper mold components 12 also includes an auxiliary clamping portion, which is used to assist in realizing the left shaping side mold 125 and the right shaping side mold 126.
