[0022] By adopting the above solution, the positioning mechanism 6 is provided, so that the mounting plate 3 can be fixed by the mounting block 2 , thereby completing the assembly of the mold 1 and the mounting plate 3 .

[0023] refer to Figure 3 The adjusting mechanism 7 includes a pulling rod 701, a vertical plate 702, two pushing columns 703 and two swinging rods 704. The pulling rod 701 is fixedly connected to the front side of the vertical plate 702. The front side of the pulling rod 701 passes through and extends out of the surface of the mounting block 2. The two pushing columns 703 are respectively fixedly connected to the top and bottom of the front side of the vertical plate 702. The two swinging rods 704 are respectively rotatably connected to the two sides of the inner wall of the placement cavity 5 through a rotating shaft.

[0031] The working principle of this utility model:

[0032] When in use, the pulling rod 701 is pulled to the right, and the pulling rod 701 drives the vertical plate 702 and the two pushing columns 703 to move to the right when moving. The pushing columns 703 squeeze the surfaces of the two swing rods 704 when moving, so that the two swing rods 704 move toward the side close to each other. When moving, the swing rods 704 squeeze the surfaces of the connecting columns 604 through the inner walls of the transmission holes 8, thereby driving the connecting columns 604 to move toward the side close to each other. When moving, the connecting columns 604 drive the lifting block 601 to move toward the side close to each other. When moving, the lifting block 601 drives the insertion rod 602 to enter the interior of the placement cavity 5 and stretches the tension spring 603 at the same time. At this time, the mold 1 and the mounting plate 3 can be assembled, and then the pulling rod 701 can be pulled in the opposite direction, and its fixation is completed after the insertion rod 602 penetrates into the interior of the socket 4.

[0033] To sum up: the connection structure of the extrusion mold for the plastic core rod solves the problem that the extrusion mold will be blocked or damaged after long-term use by setting the mold 1, the mounting block 2, the mounting plate 3, the jack 4, the placement cavity 5, the positioning mechanism 6, the lifting block 601, the insertion rod 602, the tension spring 603, the connecting column 604, the adjusting mechanism 7, the pulling rod 701, the vertical plate 702, the pushing column 703, the swing rod 704, the transmission hole 8, the guide plate 9 and the guide rod 10. The problem that the extrusion mold will be blocked or damaged after long-term use is solved. At this time, the blocked material is difficult to clean. When this happens, it will affect the processing of the plastic core rod, thereby affecting the subsequent use.
