Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

Example 1:

this embodiment provides a concrete structure of integral type aluminium alloy extrusion die, as shown in fig. 1-4, including

mould body

1, 1 top center department of mould body is provided with mould support 4, it has seted up seam room 3 to go up mould support 4 bottom, it sets up the diffluence pass 2 that a plurality of and seam room 3 are linked together to go up the mould support 4 outside, the discharge gate 7 that is linked together with seam room 3 is seted up to mould body 1 bottom, it is connected with lower mould support 5 to go up mould support 4 bottom, form runner gap 6 between lower mould support 5 and the discharge gate 7, be provided with last mould work area 9 and lower mould work area 8 that are used for controlling the aluminium alloy structure in the runner gap 6.

Further, the die body 1 adopts a cylindrical structure.

Furthermore, the upper die working belt 9 and the lower die working belt 8 are connected with the upper die support 4 through supporting pieces.

Further, the lower die working belt 8 is of a U-shaped structure, the number of the upper die working belts 9 is two, and the two upper die working belts 9 are respectively connected with two ends of the lower die working belt 8.

Further, the lower die support 5 is connected with the side wall of the discharge port 7.

The working principle, referring to fig. 1-4, the heated aluminum bar enters the shunting port 2 under the external force of the aluminum profile extruder, the aluminum bar respectively enters the welding chamber 3 after passing through a plurality of shunting holes, the aluminum entering the welding chamber 3 through the shunting port 2 is in the welding chamber 3 in the condition of external force extrusion, and the aluminum in the flow welding is shaped by the lower die working belt 8 and the upper die working belt 9 and then extruded into the aluminum profile in the gap of the runner gap 6.

This application has other with reposition of redundant personnel mould welding extrusion design, processing commonly used, specifically is to process reposition of redundant personnel hole reposition of redundant personnel mouth 2 with CNC in mould aluminium bar pan feeding mouth department, reuse T type milling cutter through reposition of redundant personnel hole entering mould in processing seam room 3, the processing mould public head under empty sword pan feeding dead sword 10.

This application subtracts the surplus when the discharge of copper electrode sparking and polishing with the copper electrode wire-electrode cutting aluminium alloy shape during wire-electrode cutting, throws into the mould at lower mould support department 5 discharge with the copper electrode, until driving through seam room 3. And striking electric sparks on the original shape by using the copper electrode with the increased allowance until the copper electrode is driven to the depth to leave the lower die working belt 8 and the upper die working belt 9 of the lower die working belt. Thus, the blank knife 11 at the discharge port of the lower die and the blank knife 12 at the discharge port of the upper die are shaped.

The application: the aluminum profile opening position is smaller, generally below 1.5mm, the actual size is smaller than 1.0mm after the discharge port is emptied by electric sparks, and the conventional shunting die welding is that an upper die and a lower die are combined through a seam allowance and a pin, so that the support cannot bear the extrusion force during extrusion, the extrusion is deviated, the extrusion is lost, and the die is scrapped.

The integral welding split-flow die is an integral die, a lower die support 5 is arranged at the lower die, an upper die support 4 is arranged at the upper die, the lower die and the upper die are of an integral structure, the supporting force is mutually connected, and the supporting size of the upper die is not restricted by the opening position of the section.

The above description is only exemplary of the present invention and should not be construed as limiting the present invention, and any modifications, equivalents and improvements made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
