Description

Technical Field

[0001] The utility model relates to the technical field of steel ball molds, in particular to a mold for a high-chromium steel ball production line. Background Technique

[0002] High-chromium steel balls are a kind of steel material with high strength, high hardness and wear resistance, and are usually used to manufacture industrial products such as bearings, automotive parts, abrasives, etc. High-chromium steel balls usually contain a relatively high proportion of chromium elements. Through heat treatment processes such as quenching and tempering, the hardness and wear resistance of the material are improved. During use, high-chromium steel balls can usually withstand high pressure and friction, and at the same time have good corrosion resistance. Therefore, they have a wide range of applications in the industrial field. In the production of high-chromium steel balls, molds are required to form the high-chromium steel balls.

[0003] The existing molds for high-chromium steel ball production lines usually consist of an upper mold, a lower mold and a mold frame. After the upper and lower molds are combined, liquid injection is carried out through a liquid injection port. When injecting liquid, metal liquid is likely to remain at the liquid injection port. Then, after the high-chromium steel balls are formed, the residual metal liquid is likely to accumulate at the liquid injection port to form a blockage of the liquid injection port. Therefore, it is necessary to manually clean the debris, and the operation of manually cleaning with tools is rather cumbersome and inconvenient; moreover, after the steel balls are formed, it is necessary to manually trigger the steel balls for demolding, and it is not convenient to manually operate the steel balls to be removed from the inside of the lower mold, and the operation is rather cumbersome and inconvenient. For this reason, we propose a mold for a high-chromium steel ball production line. Content of the Utility Model

[0004] The purpose of the utility model is to provide a mold for a high-chromium steel ball production line to solve the problems of inconvenient manual cleaning of the liquid injection port and inconvenient manual operation of the steel balls to be removed from the inside of the lower mold as mentioned in the above background technique.

[0013] Preferably, a spring for fitting inside the movable hole is provided at the top of the outer ring.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. When the upper die is lifted by the telescopic rod in the present utility model, the servo motor drives the rotating plate to rotate the telescopic rod and the upper die by 90 degrees. At the same time, the rotating motor operates to drive the cleaning rod and the rotating head to rotate.
