The invention discloses a forming technology structure for a sand mold casting head. The forming technology structure is applied to an iron mold (1). The iron mold (1) is provided with a main pouring gate (4) and a casting cavity corresponding to a cast product (8) in shape. The same sand mold technology is adopted for manufacturing the casting head (5) and the casting cavity, and the casting head (5) and the casting cavity are synchronously and integrally formed at a time through a special tool or die. By means of the above technical scheme, prefabrication, storage and installation of the casting head are omitted, labor is saved, input of special equipment is avoided, the production field is saved, and molding sand waste in the casting head prefabricating process is avoided. In the sand mold thermal forming process and the casting head forming process, waste heat can be sufficiently utilized, and the production energy consumption is reduced. The casting head and the casting cavity are in seamless connection, smoothness of a pouring system is ensured, and the defects such as floating of the casting head are avoided.
Description
technical field [0001] The invention belongs to the technical field of casting technology and its equipment. More specifically, the present invention relates to a molding process of a sand casting riser. In addition, the present invention also relates to a process structure applied to the process. Background technique [0002] In the foundry industry, in molding production, due to the limitation of technology, it is necessary to prefabricate the riser during molding, so that the casting metal liquid can be smoothly injected into the sand mold cavity. There are following drawbacks in this production process technology: [0003] 1. Prefabrication of sprue risers: Before modeling, sprue risers need to be made in advance. Foundry companies need to configure necessary production sprue riser equipment, and manual completion of sprue riser production and drying is required; [0004] 2. Riser reserve: The prefabrication process of the pouring riser requires a certain site for the...
