Description

Technical Field

[0001] The utility model relates to the technical field of casting pouring molds, in particular to a casting pouring mold for suppressing the generation of hot spots in castings. Background Technique

[0002] Casting is one of the basic processes in modern equipment manufacturing industry. It refers to the process of melting metal into a liquid meeting certain requirements and pouring it into a mold, and obtaining castings with predetermined shapes, sizes and properties after cooling and solidification, and finishing treatment. Since the casting blank is nearly formed, it can achieve the purpose of avoiding or minimizing machining, which can reduce costs and production time to a certain extent. For parts with complex shapes and difficult to machine by cutting, casting is a relatively economical method for forming blanks.

[0003] For example, in the Chinese patent with the publication number CN219274455U, a casting pouring mold is proposed. The assembly includes a base, a bottom mold and a top mold. The top of the base is connected to the bottom mold through a shock absorption assembly. An equipment slot is provided at the bottom of the base. Supporting feet are fixedly connected to the bottom of the base and located circumferentially around the equipment slot. An adjustable moving assembly is provided in the equipment slot. The pouring mold of the utility model is convenient to move, and a shock absorption assembly is provided to reduce the influence of vibration during movement on the molten metal in the mold, improving the forming quality of the casting. The bottom mold and the top mold are arranged on the base, and an adjustable moving assembly is provided at the bottom of the base. The moving rollers can rotate into the equipment slot. When movement is needed, the moving rollers are rotated to the bottom of the equipment slot to facilitate the movement of the entire mold equipment. However, in this solution, during the casting manufacturing process, it is not possible to effectively deal with suppressing hot spots (i.e., local high-temperature areas in the casting), because hot spots will cause uneven shrinkage of the casting, thereby causing defects such as shrinkage cavities and cracks. Therefore, we propose a casting pouring mold for suppressing the generation of hot spots in castings. Content of the Utility Model
