Problems solved by technology

However, according to the design of ordinary flat die, after the die is extruded on the machine, the surface of each joint will often be broken. Even if the extruding speed is quite slow, the remaining pressure will be thinner, and the material supply will still be insufficient, which will seriously affect the production and use.
After analysis, it is found that one of the main reasons for this phenomenon is that the metal is taken out of the diversion groove with the excess pressure during extrusion production and shearing, resulting in broken surfaces at the joints due to insufficient metal supply.

Embodiment 1

[0036] Please refer to Figure 1 to Figure 4 Shown, embodiment one of the present invention is:

[0037] A kind of mold that diversion groove is connected with T-shaped groove, comprises guide mold 1, and the shape of described guide mold 1 is cylinder; Described guide mold 1 is from the feed end of guide mold 1 to guide mold The axis of the discharge end of 1 is provided with diversion groove 11, T-shaped groove 12, working belt 13 and discharge port 14 in sequence;

[0038] The diversion groove section of the guide groove 11 along the axial direction of the guide mold 1 is rectangular, and the T-shaped groove cross section of the T-shaped groove 12 along the axial direction of the guide mold is rectangular; the T-shaped groove cross section and the flow guide The vertical line of the long side of the groove cross-section coincides with the axis of the guide mold 1; the length of the short side of the T-shaped groove cross-section is greater than the length of the short side...

Abstract

The invention relates to the technical field of mold processing, in particular to a mold with a diversion groove connected with a T-shaped groove, including a guide mold, the shape of the guide mold is a cylinder; A diversion groove, a T-shaped groove, a working belt and a discharge port are arranged successively on the axis from the material end to the discharge end of the guide die; The T-shaped groove section of the T-shaped groove along the axial direction of the guide die is rectangular; the vertical line of the long side of the T-shaped groove cross-section and the diversion groove cross-section coincides with the axis of the guide die; the beneficial effects of the present invention are : Design the T-shaped groove on the basis of the original diversion groove. The design of the T-shaped groove can effectively prevent the metal from being carried away due to the insufficient depth of the diversion groove designed by the ordinary flat die or other reasons. Out of the diversion groove, resulting in insufficient metal in the diversion groove, the mold structure design is reasonable, the manufacturing difficulty is low, the produced profile is stable in size, and the pass rate of the machine is high.

Description

technical field [0001] The invention relates to the technical field of mold processing, in particular to a mold with a diversion groove connected with a T-shaped groove. Background technique [0002] As aluminum alloy extrusions are used more and more widely in various fields, the types of profiles are becoming more and more diverse, but they are always inseparable from the two categories of hollow profiles and solid profiles. When designing solid profiles, flat die design is generally used at present. However, according to the design of ordinary flat die, after the die is extruded on the machine, the surface of each joint will often be broken. Even if the extruding speed is quite slow, the remaining pressure will be thinner, and the material supply will still be insufficient, which will seriously affect the production and use. . After analysis, it is concluded that one of the main reasons for this phenomenon is that the metal is taken out of the diversion groove with the ...
