Embodiment 1

[0047] Please refer to Figure 1 to Figure 8 Shown, embodiment one of the present invention is:

[0048] An extrusion die, comprising an upper die 1 and a lower die 2 connected to each other;

[0049] The middle part of the upper die 1 is provided with a tongue core 11, and the tongue core 11 is arranged from the feed end of the upper die 1 to the discharge end of the upper die 1, and extends out of the discharge end of the upper die 1 to form a protrusion 111, the protrusion 111 is provided with a first working belt 12, and the side of the first working belt 12 close to the discharge end of the upper mold 1 is provided with a lower empty knife 13;

[0050] There are four distribution holes 14 running through the upper die evenly distributed on the feed end circumference surface of the upper die 1, and a splitter bridge 15 is arranged between the split holes 14, and the split bridge 15 is formed from the feed end of the upper die 1. The section from the inlet side to the out...

Abstract

The invention relates to the technical field of mould processing, and particularly relates to an extrusion mould. The extrusion mould comprises an upper mould and a lower mould which are mutually connected; a tongue core is arranged at the middle part of the upper mould and is arranged from the feeding end of the upper mould to the discharging end of the upper mould,, the discharging end extendingout of the upper mould forms a bulge, a first working belt is arranged on the bulge, a lower clearance is arranged on one side of the discharging end, near to the upper mould, of the first working belt, four flow splitting holes penetrating through the upper mould are evenly distributed on the peripheral surface of the feeding end of the upper mould, and a flow slipping bridge is arranged betweenthe flow splitting holes. The extrusion mould has the beneficial effects that: the cross section of the flow splitting bridge is arc, the structure design of the upper mould adopts the flow splittingbridge to provide the optimal supporting, the stability and the strength of the mould are optimal, the feeding is guaranteed to the greatest extent, the extrusion force of a pressure bearing surfaceacting on the mould is reduced to the greatest extent, the overall structure design of the mould is reasonable, so that the extrusion force acting on the mould is reduced, and the production efficiency of extrusion is also improved.

Description

technical field [0001] The invention relates to the technical field of die processing, in particular to an extrusion die. Background technique [0002] Die design is one of the key factors in aluminum alloy extrusion production. A die with a reasonable structure has good strength, low extrusion force, good stability, large throughput, long life and high pass rate. The splitter mold with closed cavity needs to divide the ingot into several strands of metal and then weld the extruded profile, so the extrusion force of the splitter die is large, and if the extrusion force of the splitter die is not handled properly, the speed will not increase when extrusion occurs. To go up, you can only squeeze slowly, and the efficiency is very low. In severe cases, the car will be stuffy and cannot be squeezed, and the mold will be easily squeezed and the mold will be scrapped. Therefore, reducing the extrusion force acting on the mold is the top priority of the designer, and it is particu...
