Description

Technical Field

[0001] The utility model relates to the technical field of positioning mechanisms, in particular to a positioning component and a core molding die. Background Art

[0002] The core molding die is an important tool for manufacturing cores in the casting process. Cores are usually made by mixing sand with resin or other binders and are used to fill the internal cavities of castings to form the desired shapes.

[0003] The core die is usually composed of two parts, an upper die and a lower die, which can be easily opened and closed to fill and remove the core. According to the requirements of the casting, there is a specific cavity in the die. The design of this cavity needs to consider factors such as fluidity and cooling rate to ensure good casting results. The die material is usually selected from wear-resistant alloy steel, aluminum alloy or resin to withstand repeated use. Since it will come into contact with high-temperature molten metal during the casting process, the die must have good thermal stability to prevent deformation or damage.

[0004] During the process of researching and developing the core model in the laboratory, it is necessary to frequently adjust the position of the core model to facilitate the debugging by the operator. The existing core molding table has a large table area and a large working range, making it very inconvenient for the operator to operate and prone to operation errors, resulting in a reduction in the research and development efficiency.
