Description

Technical Field

[0001] The utility model relates to a CPVC extrusion flow distribution support with double inclined plane compression. Background Art

[0002] The conventional flow distribution support of the CPVC extrusion die adopts a straight flow distribution support. Although it has the characteristic of simple processing, due to the processing characteristics of the CPVC material, it is not possible to produce pipes with too large a compression ratio. When producing pipes with a relatively thick wall thickness, the straight flow distribution support needs to increase the compression ratio to achieve this. Therefore, the effect of producing CPVC with the conventional straight flow distribution support is poor. Content of the Utility Model

[0003] The utility model provides a CPVC extrusion flow distribution support with double inclined plane compression, including a flow distribution support main body, and a plurality of circumferentially arranged flow channels are arranged on the flow distribution support main body, and the flow channels incline outwards from the feed end of the flow distribution support main body to the discharge end of the flow distribution support main body.

[0004] In one or more embodiments, the flow channel is provided with a feed port and a discharge port, and the feed port and the discharge port are partially oppositely arranged.

[0005] In one or more embodiments, the discharge port is closer to the outside of the flow distribution support main body relative to the feed port.

[0006] In one or more embodiments, the flow distribution support main body forms a cylindrical shape.

[0007] In one or more embodiments, the flow distribution support main body is provided with a central part and an outer circular part, the flow channel is arranged between the central part and the outer circular part, and a connecting bridge is arranged between the central part and the outer circular part.

[0008] In one or more embodiments, a pointed part is formed on the side surface of the feed end of the connecting bridge.

[0009] Advantageous Effects of the Utility Model: The flow distribution support with double inclined plane feeding adopted in this design can well adapt to the production of CPVC materials. Since the inclined plane feeding can well provide a compression in the extrusion direction, the compression ratio of the die can be correspondingly made smaller, and the outer diameter of the die does not need to be too large, which is very suitable for producing CPVC materials. By using the design of the flow distribution support with double inclined plane compression, the defects of easy generation of flow splitting lines and uneven inner wall in the production of CPVC materials by general dies are effectively eliminated.
