AI Technical Summary
Technical Problem
In the existing technology, when the connection structure between the extruder and the pipe die is connected by conventional T-bolts, additional tools are required for rotation and positioning, which affects the reliability of the connection and the installation efficiency.
Method used
The method involves setting identical connection openings in the same position and shape on both the extruder and the pipe die, and adding anti-rotation parts to the bolts to prevent them from rotating during connection. The bolts are then quickly locked by rotating the nut.
Benefits of technology
It improves the connection reliability and installation efficiency of extruders and pipe dies, ensuring connection stability and rapid assembly.

Abstract
This utility model discloses a connection structure for an extruder and a pipe die, including a first flange fixed to the extruder, a second flange fixed to the pipe die, and multiple bolts. The first flange has multiple first connection openings on its outer circumference, each extending radially along the first flange. The second flange has multiple second connection openings with the same position and shape as the first connection openings. Each bolt is provided with an anti-rotation portion, the thickness of which along the bolt's radial direction is no greater than the width of the first connection opening, and the width of which along the bolt's radial direction is greater than the width of the first connection opening. When each bolt passes through the corresponding first and second connection openings and is connected to a nut, at least a portion of the anti-rotation portion is located within either the first or second connection opening. This connection structure facilitates assembly and disassembly, effectively improving the reliability and installation efficiency of the connection between the extruder and the pipe die.
