The circumference of the copper arc segment is provided with multiple fitting holes corresponding to each threaded countersunk hole, and the bolt fixes the copper arc segment to the copper strip through the fitting holes.

[0005] Preferably, the extrusion pad has an axisymmetric structure, with multiple copper strips evenly distributed and embedded in the corresponding sink.

[0006] Preferably, the main body of the extrusion bar is mounted on the rear side of the extruder and forms a larger diameter section through a transition zone, with the outer edge of the transition zone along the axial longitudinal section profile being arc-shaped.

[0007] Preferably, multiple countersunk holes and mounting holes are evenly distributed circumferentially along the transition zone.

[0021] like Figure 1-4 As shown, this utility model provides an extrusion rod 200 with enhanced heat dissipation function, which includes: being able to connect to the extrusion pad 100 and be installed in the extruder, thereby constituting an extrusion device.

[0022] The compression pad 100 includes a compression pad rear end 102 and a compression pad front end 101.

[0023] The extrusion rod 200 includes: mounting hole 201, countersunk hole I 202, transition zone 203, extrusion rod body 204, copper strip 205, mounting plane 206, countersunk groove 207, copper strip side I 208, copper strip side II 209, outer arc 210, inner arc 211, countersunk groove side I 212, countersunk groove side II 213, and countersunk groove bottom 214.

[0024] Preferably, the extrusion pad 100 has an axisymmetric structure, for example, it is configured as a frustum of a cone with an isosceles trapezoidal cross-section in the left view, located at the foremost end of the extrusion rod 200. The extrusion pad rear end 102 is adjacent to the extrusion rod 200. The extrusion pad front end 101 and the extrusion pad rear end 102 are parallel.

[0025] Preferably, the axis of the extrusion rod 200 is coaxial with the axis of the extrusion pad 100. The extrusion rod body 204 has an axisymmetric structure. Compared with the front side used for mounting the extrusion pad 100, the rear side used for mounting in the extruder has a larger diameter portion formed by the transition region 203. This transition region 203 has an axisymmetric shape, such as... Figure 1As shown in the axial longitudinal section diagram, the outer edge of the single-sided profile is arc-shaped. For example... Figure 2 As shown, eight countersunk holes I 202 and mounting holes 201 are evenly distributed circumferentially along the transition zone 203. The axis of the countersunk holes I 202 is parallel to the axis of the extrusion rod 200, and the axis of the mounting holes 201 is parallel to the axis of the extrusion rod 200. Preferably, the axis of the mounting holes 201 is coaxial with the axis of the countersunk holes I 202.

[0026] Thus, the countersunk hole I 202 and the mounting hole 201 connect to form a through hole opening onto the mounting plane 206, which can be used to pass through fastening bolts to connect the extrusion rod 200 to the extruder via the mounting plane 206 on the rear end side. The mounting plane 206 is perpendicular to the axis of the extrusion rod 200, and the axis of the extrusion rod 200 passes through the center of the mounting plane 206.

[0027] In addition, such as Figure 1 , 3 As shown in Figure 4, eight copper strips 205 are distributed inside the outer peripheral surface of the extrusion rod 200 (preferably uniformly, but not limited to this). Among them, eight grooves 207 extending along the axial direction are opened at intervals along the circumferential direction of the outer peripheral surface, respectively for embedding the corresponding copper strips 205.

[0028] The cross-sectional profile of copper strip 205 consists of copper strip side surface I 208, copper strip side surface II 209, outer arc 210, and inner arc 211. Copper strip side surface I 208 and copper strip side surface II 209 are parallel to each other. The radius of curvature of the outer arc 210 is the same as the radius of the extrusion rod 200. The inner arc 211 is concentric with the outer arc 210, and the radius of curvature of the inner arc 211 is smaller than that of the outer arc 210.

[0029] The sink 207 includes: sink side I 212 and sink side II 213 extending parallel to each other, and sink bottom 214 formed as an arc, the size and shape of which are consistent with the inner arc 211 of the copper strip 205.

[0030] In this way, the size of the copper strip 205 can be made consistent with the size of the corresponding sink 207. During installation, the copper strip 205 is placed into the sink 207 after being frozen and shrunk. Then, two copper half-rings 215 are installed and fixed by mating them together from opposite sides around the circumference. Of course, this is not limited to this method; they can also be fixed by being staggered along the axial direction.

[0031] Multiple countersunk holes 217 are evenly distributed on the outer arc of each copper strip 205, which ensures that the spacing of each countersunk hole 217 is consistent, and the position and size of the countersunk holes 217 on each copper strip 205 are consistent.

[0032] The two copper semi-rings 215 are identical in size, with the inner diameter of the copper semi-ring 215 matching the diameter of the extrusion rod body 204. The outer diameter of the copper semi-ring 215 is smaller than the diameter of the front end 101 of the extrusion pad, which is the maximum diameter of the extrusion pad.

[0033] The copper half-ring 215 has several interconnected countersunk holes II 218 and threaded through holes 219 evenly distributed around its circumference. After the two copper half-rings 215 are fastened to the extrusion rod body 204, the axis of the threaded countersunk hole 217 on the copper strip 205 is aligned with the axis of the countersunk hole II 218 and the threaded through hole 219 on the copper half-ring 215 on the same line.

[0034] Bolt 216 is screwed into the countersunk hole II 218 and threaded through hole 219 on the copper half ring 215, and then into the threaded countersunk hole 217 in the copper strip 205 to fix the copper half ring 215 and form the entire copper ring.

[0035] The above example shows two copper semi-rings, but it is not limited to this; arc segments with corresponding angles can also be used, collectively referred to here as copper arc segments. The countersunk hole II 218 and the threaded through hole 219 that are connected to each other are collectively referred to as mounting holes.
