Description

Technical Field

[0001] The utility model relates to the technical field of extruders, in particular to a fixed extrusion pad with a through-rod and an extruder. Background Art

[0002] An extruder is a type of equipment widely used in industries such as metalworking, plastic molding, and food processing. Its primary function is to apply pressure through a mechanical or hydraulic mechanism to force raw materials through a die, creating a product of a specific shape. With the continuous development of industrial production, the application range of extruders is expanding, and the extrusion process is also constantly developing and improving.

[0003] The fixed extrusion pad is an indispensable component of the extruder. Its main function is to support the extrusion rod and guide the flow of materials to ensure the stability of the extrusion process and the quality of the extruded product.

[0004] As a crucial force-transmitting and guiding component in an extruder, the mandrel typically requires additional drive devices or mechanical structures to ensure its stable motion. This not only increases mechanical complexity and occupies more space, but also prevents the mandrel from effectively coordinating with the fixed extrusion pad, resulting in uneven stress transfer and affecting the precision and stability of the extrusion results.
