[0033] The shunt bridge assembly 69 includes a protective layer 1 691, a protective layer 2 692 and a metal base layer 694. One side of the protective layer 1 691 is compounded with the protective layer 2 692. One side of the protective layer 2 692 is compounded with a reinforcement layer 693. The thickness of the protective layer 2 692 is twice that of the protective layer 1 691, and the thickness of the protective layer 2 692 is the same as that of the reinforcement layer 693. One side of the reinforcement layer 693 is compounded with the metal base layer 694. A connector 682 is embedded on the top of the shunt bridge assembly 69, and the connector 682 is π-shaped.

[0034] In this example, the guide groove at the bottom of the lower mold assembly 5 is used to facilitate the discharge of the profile after extrusion molding, the cross bar 66 can be used to support the auxiliary tube 63 and the mold core 65, and the inclined rod 64 can be used to reinforce the cross bar 66 and the mold core 65, thereby improving the stability of the mold core 65 when in use and reducing the deviation of the mold core 65 when in use, thereby ensuring the use effect of the entire mold, the length of the support bar 1 681 and the support bar 2 683 are different, and the two ends of the support bar 1 681 and the support bar 2 683 are respectively connected to the inner wall of the built-in component 68 and the side wall of the diverter bridge assembly 69, which can realize the diverter bridge assembly 69. The side support and reinforcement are used to initially divide the cavity enclosed by the built-in component 68 and the shunt bridge component 69. The reinforcing strip 684 can be used to reinforce the support strip 2 683 and the support strip 1 681 respectively, and the cavity enclosed by the built-in component 68 and the shunt bridge component 69 is divided again to reduce the impact of the molten casting on the shunt bridge component 69.

The protective layer 2 692 itself has a certain wear resistance, and cooperates with the protective layer 1 691 to further improve the wear resistance of the diverter bridge assembly 69. As the bottom layer of the protective layer 1 691, it provides a good bonding foundation to prevent the protective layer 1 691 from falling off during use. The protective layer 1 691 can be used to protect the surface of the diverter bridge assembly 69. The protective layer 1 691 has extremely high hardness, low friction coefficient, good wear resistance and corrosion resistance. The protective layer 1 691 can form a hard protective film on the surface of the diverter bridge, effectively reducing the friction between the metal and the diverter bridge assembly 69, reducing wear and energy loss. At the same time, the protective layer 1 691 has a high surface smoothness, which is conducive to the flow of metal and improves the surface quality of the extruded product.

The top of the inner cavity of the limiting disk 1 overlaps with the limiting shell 61, and a limiting groove 12 is provided at the bottom of the limiting disk 1, which is engaged with the limiting bolt 67.

[0037] In this embodiment, the guide block 631 can be used to guide the connection between the auxiliary tube 63 and the built-in component 68, thereby reducing the position deviation of the auxiliary tube 63 when it is installed inside the limiting shell 61, and improving the accuracy of the position of the auxiliary tube 63 when it is installed. The limiting bolt 67 can be used to fix the connection between the limiting shell 61 and the auxiliary tube 63, thereby reducing the looseness of the auxiliary tube 63 when it is installed and used.

The plug-in of 631 can limit the position of the guide block 631, thereby further strengthening the installation of the auxiliary tube 63, ensuring the stability of the auxiliary tube 63 inside the built-in component 68, and further ensuring the stable use of the diverter bridge assembly 69. At the same time, the plug-in rod 11 can reduce the obstruction of the diverter bridge assembly 69, thereby ensuring the normal use of the built-in component 68 and the diverter bridge assembly 69. After removing the plug-in rod 11 and the limit bolt 67, the built-in component 68 and the diverter bridge assembly 69 can be quickly disassembled, and the overall operation is more convenient.

[0038] Embodiment 3: According to Figure 1-Figure 4 As shown, the outer ring surface of the limiting shell 61 is fixedly connected with a reinforcement ring 611, the bottom of the reinforcement ring 611 is fixedly connected with an extension rod 62, a buffer rod 52 is inserted into the extension rod 62, the bottom of the buffer rod 52 is fixedly connected with a guide ring 53, the top of the guide ring 53 is fixedly connected with a spring, the top of the spring is overlapped with the extension rod 62, the inner ring surface of the guide ring 53 is fixedly connected with the lower mold assembly 5, the outer ring surface of the buffer rod 52 is slidably connected with the limiting ring 2, the side walls of the limiting ring 2 and the buffer rod 52 are provided with positioning holes, and the bottom of the limiting ring 2 is fixedly connected with a connecting ring 3, the bottom of the connecting ring 3 is slidably connected with an extension piece 511, one side of the extension piece 511 is hinged with a hinge 51, one end of the hinge 51 is hinged with a fixed block 4, and one side of the fixed block 4 is fixedly connected to the outer ring surface of the lower mold assembly 5.

[0039] In this embodiment, the reinforcing ring 611 can be used to support and reinforce the outer ring surface of the limiting shell 61, thereby improving the strength of the limiting shell 61. At the same time, the reinforcing ring 611 can be used to reinforce the top of the extension rod 62 to ensure the stable installation and use of the extension rod 62. The extension rod 62 and the buffer rod 52 are plugged in to guide the installation of the reinforcing ring 611 on the top of the guide ring 53, thereby guiding the connection between the upper mold assembly 6 and the lower mold assembly 5, reducing the position deviation when the upper mold assembly 6 and the lower mold assembly 5 are connected. The bottom of the extension rod 62 can be reinforced by a spring. The part is used for buffering, reducing the impact of the extension rod 62 and the reinforcement ring 611 on the guide ring 53, the installation height of the connecting ring 3 can be adjusted by the limit ring 2, the connection between the limit ring 2 and the guide ring 53 can be fixed by the positioning hole, and the sliding of the limit ring 2 and the connecting ring 3 can be reduced, the extension piece 511 can be used to achieve the connection between the hinge 51 and the connecting ring 3, the fixing block 4 can be used to achieve the connection between the hinge 51 and the lower mold assembly 5, the hinge 51 can be used to support and reinforce the connecting ring 3 and the lower mold assembly 5, and the stability of the connecting ring 3 during installation and use is improved.
