Description

Technical Field

[0001] This utility model relates to the field of casting and molding technology, specifically to a twin-screw granulator housing processing device. Background Technology

[0002] As a core load-bearing component, the casing of a twin-screw granulator needs to maintain structural stability under high temperature and high pressure. Its molding quality directly affects the operating accuracy and service life of the granulator. Integrated casting molding technology, with its advantages of no splicing and high strength, has become the mainstream processing method for high-end casings, which can meet the stringent requirements of complex cavities and sealing performance.

[0003] However, traditional processing equipment is difficult to adapt to the differentiated requirements brought about by the complex structure of the casing when it is used for integrated casting. Due to the significant difference in wall thickness in different parts of the casing, the flow and heat dissipation of molten metal in the cavity are different. Existing equipment lacks a targeted control mechanism and it is difficult to dynamically adjust the solidification conditions according to the regional characteristics. Thick-walled areas are prone to solidification delay due to slow heat dissipation, resulting in shrinkage cavities or porosity. Thin-walled areas, on the other hand, are prone to insufficient filling of molten metal due to excessive cooling, resulting in material shortage. This imbalance in solidification rate not only reduces the density of the casing, but also causes hidden cracks due to uneven stress distribution, which restricts product quality and processing efficiency. Therefore, there is an urgent need for a twin-screw granulator casing processing device to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a twin-screw granulator housing processing device to solve the problem mentioned in the background art that, when traditional processing devices are used to integrally cast the housing of a twin-screw granulator, the complex structure of the housing and the large differences in wall thickness make it difficult to accurately control the solidification rate of the molten metal in different areas.
