[ detailed description ] embodiments

The following examples are further to explain and supplement the present invention, and do not constitute any limitation to the present invention.

Example 1

As shown in fig. 1-4, the multi-cavity aluminum profile mold of the embodiment includes an upper mold 10 and a lower mold 20, the upper mold 10 is provided with a mold core 30 extending out of a feeding material 10 and embedded into the lower mold 20, the upper mold 10 is provided with at least one feeding cavity 11, the feeding cavity 11 is divided into two parts by a shunting bridge 12, the mold core 30 is arranged on the shunting bridge 12, an outer edge of the mold core 30 gradually increases from one end close to the shunting bridge 12 to one end far away from the shunting bridge 12, and a width of the shunting bridge 12 near the middle of the mold core 30 is greater than widths of two ends close to the feeding cavity 11;

the upper die 20 is provided with a welding cavity 22 on the lower die 20, the size of the welding cavity 22 is the same as that of the feeding cavity 11, and the bottom of the welding cavity 22 is also provided with a secondary welding chamber 23.

Through being equipped with a plurality of cavitys on last mould 10 and lower mould 20, at the extrusion in-process, can a plurality of cavitys simultaneously shunt and the ejection of compact to the aluminium ingot, compare the mould of single cavity, can reduce the pressure that the mould receives in the extrusion process to the mould rate of exploding has been reduced, and a mould multicavity can improve holistic production efficiency, in addition, mold core 30 from the top down by thin thickening, help the extrusion in-process to the cutting apart of aluminium ingot, make the aluminium ingot shunted more easily.
