Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of casting molds, and more specifically, to a precise positioning cooling device for molds. Background Technique
[0002] With the continuous development of technology, metal die-casting molds have been widely used in industrial production. A large number of motorcycle braking metal parts have been transformed from traditional low-pressure casting and gravity casting to high-pressure casting. High-pressure die-casting has been widely used in industries such as automobiles, electronics, instrumentation, and aviation due to its advantages of high efficiency, less cutting, good surface finish, and superior mechanical properties. Its high efficiency, high quality, and ability to produce products with complex structures are very suitable for mass production of products.
[0003] Based on the above, the inventor found that: during the processing of motorcycle braking parts by traditional molds, in the areas where the molten metal needs to release more heat when changing from liquid to solid during the solidification process, generally, they are located at thicker wall thicknesses or higher temperatures. However, traditional molds often cannot accurately position the positions with thicker wall thicknesses or higher temperatures, resulting in hot spots in the positions with thicker wall thicknesses or higher temperatures, and further causing defects such as overall temperature imbalance of the casting, shrinkage porosity, shrinkage cavity, cold shut, and gas porosity. Therefore, in view of this, the existing structure is studied and improved to provide a precise positioning cooling device for molds, with the expectation of achieving a more practical value. Content of the Utility Model
[0004] 1. Technical Problems to be Solved
[0005] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a precise positioning cooling device for molds, which can add multiple cooling rods at the thicker wall thicknesses of the castings in the mold, so that when the molten metal changes from liquid to solid during the solidification process, the positions with thicker wall thicknesses or higher temperatures can be accurately positioned and cooled, thereby maintaining the overall temperature balance and solving the problems of shrinkage porosity, shrinkage cavity, cold shut, gas porosity and other defects in the casting caused by hot spots in the positions with thicker wall thicknesses or higher temperatures.
