[0024] See Figure 3 This utility model provides a split assembly extrusion molding die, including an upper die 1 and a lower die 4;
[0025] See Figure 1 A core post 12 is fixed on one side where the upper mold 1 and the lower mold 4 are joined; then combined with Figure 2 The core post 12 is fixedly sleeved onto the mold core 2;
[0026] In this invention, the upper mold 1 and the mold core 2 are processed separately. Then, the mold core 2 is fitted onto the core post 12 and fixed, completing the assembly with the upper mold 1. By setting the mold core 2 and the upper mold 1 as separate structures and processing them separately, this invention simplifies the structure of the upper mold 1, reduces the processing difficulty, improves processing efficiency, and shortens the mold development cycle.
[0027] As one embodiment, the upper mold 1 is fixedly connected to the guide plate 3; the upper mold 1 has a metal flow channel 11, and the guide plate 3 has a flow-dividing hole 31 that communicates with the metal flow channel 11; by setting the guide plate 3, the thickness of the upper mold 1 can be effectively reduced, and the processing difficulty can be reduced.
[0028] See Figure 4 As one embodiment, the core post 12 and the mold core 2 are threaded together, resulting in high fitting accuracy.
[0029] Furthermore, the mold core 2 is provided with a mounting hole 13; the mounting hole 13 is used for screwing in a lifting lug to facilitate lifting the mold core 2. During assembly, a handle can be inserted into the mounting hole 13 to facilitate screwing in with the core post 12.
[0030] Furthermore, a circumferential weld 21 is formed at the junction of the core post 12 and the mold core 2; this enhances the robustness of the mold core 2 and prevents it from loosening during the extrusion molding process. After the circumferential weld 21 is formed, its end face is ground smooth to facilitate assembly with the lower mold 4.
[0031] Even better, an annular bevel is provided on the upper end surface of the mold core 2 that intersects with the core column 12, which facilitates the formation of the circumferential weld 21.
[0032] Preferably, the circumferential weld 21 is formed by laser welding, which has high welding energy density and controllable width.
[0033] See Figure 5 and Figure 6 As one embodiment, at least three inserts 5 are fixedly connected between the core post 12 and the mold core 2; the inserts 5 fix the core post 12 and the mold core 2, which facilitates their disassembly.
[0034] Preferably, there are 3-6 inserts 5. Those skilled in the art can make adaptive settings according to the actual size of the mold.
[0035] In one embodiment, both the core post 12 and the mold core 2 are provided with a semi-sunken groove. After the core post 12 and the mold core 2 are sleeved together, the semi-sunken grooves are joined to form a slot 54 for accommodating the insert 5. The insert 5 is fixedly connected to the core post 12 and the mold core 2 respectively by fastening bolts 55.
[0036] Optionally, the insert 5 has two bolt holes 51, and a fastening bolt 55 is screwed into each of the two bolt holes 51;
[0037] Furthermore, the opening of the slot 54 is welded to the insert 5 to form a fixing weld 52;
[0038] Preferably, the opening of the slot 54 and the outer top edge of the insert 5 are both provided with bevels 53; during welding, this facilitates the formation of the weld 52.
[0039] In this embodiment, the core post 12 and the mold core 2 are connected by an insert 5, facilitating their assembly and disassembly. The weld length is short and concentrated on the insert 5, making cleaning easy after disassembly. The insert 5 can also be replaced periodically, extending the service life of the core post 12 and the mold core 2.
[0040] In summary, this utility model provides a split-assembly extrusion molding die. By setting the die core and the upper die as separate structures, the upper die and the die core can be processed separately. Then, the die core is sleeved onto the core post and fixed, completing the assembly with the upper die. This utility model simplifies the structure of the upper die, reduces processing difficulty, improves processing efficiency, and shortens the die development cycle.
[0041] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
