Description

Technical Field

[0001] This utility model relates to the field of gating and riser technology, specifically a lightweight irregular gating and riser forming mold. Background Technology

[0002] A riser or gating system is an auxiliary part added to the top or side of a casting to prevent defects. In the mold, the cavity of the riser or gating system is a container for storing molten metal. Its functions are multifaceted. Different risers have different forms, sizes, and locations. Therefore, the design of risers and gating systems must consider the properties of the casting alloy and the characteristics of the casting. The functions of risers and gating systems are as follows: For alloys with small volume shrinkage during solidification or alloys that do not produce concentrated shrinkage cavities, the main function of risers and gating systems is to discharge gas in the cavity and collect molten metal mixed with inclusions or oxide films at the liquid flow front to reduce defects on the casting. For castings that require control of microstructure, risers and gating systems can collect the cooled molten metal at the liquid flow front to prevent supercooled structures on the casting. For alloys with large volume shrinkage during solidification and a tendency to form concentrated shrinkage cavities, the main function of risers and gating systems is to compensate for the liquid shrinkage of the molten metal in the cavity and the shrinkage during the solidification process of the casting to obtain a dense casting without shrinkage cavities.

The main body 52 works together to evenly transport the injection molding material through the funnel 62 in the movable ring 61 into the mold assembly 49 for injection molding. The fan assembly 53 then cools the mold assembly 49. After the injection molding is completed, the telescopic rod 65 in the demolding mechanism 6 retracts, causing the movable ring 61 and the funnel 62 to rise and fall to the designated position. The injection molding main body 52 then retracts to remove the model from the mold assembly 49. Finally, the demolding ring 63 at the lower end of the funnel 62 uses the surrounding pressure to demold the model on the mold main body 52, thus completing the molding process.
