Technical Field

The utility model belongs to the technical field of casting detection processes. In particular to a water-cooling spectrum sample die which can ensure the process quality of a spectrum sample.

Background

The detection of molten iron components is an important link in casting production, castings can be poured only by molten iron with qualified components, and the most common molten iron detection method at present is detection by a spectrometer. The spectrometer is used for detecting the molten iron components, the molten iron to be detected is poured into a spectrometer sample, and the sample components represent the molten iron components. The spectrum sample was generally prepared into a circular discus having a thickness of 3mm and a trapezoidal longitudinal section (FIGS. 1 and 2). Due to the characteristics of the spectrometer, the spectrum sample for detection must be of a white structure, i.e., carbon in molten iron does not crystallize out in the form of graphite, and therefore the temperature of the mold is required to be sufficiently low. The traditional die material is red copper, but when the die material is frequently used, the temperature of the die is often increased, the whitening degree of a sample is influenced, and the detection accuracy is further influenced. In addition, red copper is expensive, which results in high cost of the mold.

SUMMERY OF THE UTILITY MODEL

The utility model provides a water-cooling spectrum sample die aiming at the problems.

The technical scheme adopted by the utility model for realizing the purpose is as follows: the utility model provides a water-cooling spectrum sample mould, characterized by, includes water tank, net mould and movable mould, the water tank is connected in the net mould outside, through hinge connection between net mould and the movable mould, the inside cluster water cavity that is equipped with of movable mould, the cluster water cavity is linked together with the water tank through water tank intercommunication hose, be equipped with the die cavity that is used for forming the sample on the net mould, the sample detection face that the die cavity corresponds is close to the water tank.

The area of the water stringing cavity communicated with the water tank through the water tank communicating hose is not less than 60% of the cross section of the water stringing cavity, so that the movable mold has a good cooling effect.

The test sample detection surface corresponding to the cavity is close to the water tank, the cooling effect is best, the complete blank of the test sample is guaranteed, meanwhile, the shape of the test sample is consistent with the direction of the draft angle in the casting process, and the test sample can be smoothly taken out from a clean die.

The water tank communication hose and the cleaning mold are sealed by a sealing layer made of heat-resistant and water-resistant materials, so that water leakage accidents are avoided.

The movable mould is 5mm less than the net mould in the direction of height, and both lock through the kayser, and after the assembly, leave 5mm gap between movable mould lower extreme and the bottom plate, the movable mould rear wall lower part is equipped with the valve that drains.

The side wall of the water tank is 50mm higher than the upper plane of the cleaning die.

The utility model uses hot die steel to make a sample die, and is provided with a corresponding water cooling system and accessories such as a hinge, a latch, a handle, a water drain valve and the like, so that the movable die can freely open and close under the condition of ensuring the communication of a water pipe. The moving die is 5mm smaller than the clean die in the height direction. After the assembly is completed, a gap of 5mm is reserved between the lower end of the movable die and the bottom plate, so that the movable die can still be freely opened and closed when small impurities are left on the bottom plate. The side wall of the water tank on the outer side of the clean die is 50mm higher than that of the clean die, so that the situation that molten iron overflows into the water tank and is dangerous is avoided. A thermometer is further provided for detecting the temperature of the cooling water. The material of the die body is hot die steel instead of red copper, so that the material cost is reduced, and the service life is prolonged.
