Abstract
The invention relates to a large-sized die with stepped diversion, multi-stage diffluence and complicated section. The die contains an upper die (1), a lower die (2) and a die cushion (3), wherein the upper die (1), the lower die (2) and the die cushion (3) are sequentially superposed, the middle of the feed end of the upper die (1) is provided with a through hole, a first-stage diffluence bridge (101), second-stage diffluence bridges (102) and third-stage diffluence bridges (103) are arranged in the through hole, the first-stage diffluence bridge (101) is arranged in the middle of the through hole, the second-stage diffluence bridges (102) are arranged at both ends of the through hole, the height of the second-stage diffluence bridges (102) is lower than that of the first-stage diffluence bridge (101), the third-stage diffluence bridges (103) are arranged at the four corners of the through hole, and the height of the third-stage diffluence bridges (103) is lower than that of the second-stage diffluence bridges (102). The large-sized die with stepped diversion, multi-stage diffluence and complicated section has longer service life, enhances the yield and the quality of a product and can enhance the production efficiency of the product.
Description
(1) technical field
The present invention relates to a kind of mould, especially relate to the large-size complex-cross-section mold of a kind of stepped diversion, multi-stage diffluence.
(2) background technology
At present, there is the situation that is prone to loss in process of production in the extrusion die of employing, and the spoilage of mould is higher; Often need to change, not only strengthened production cost and incured loss through delay production efficiency, simultaneously; When extrusion production; Owing to all adopt an extrusion modling, aluminium section bar is often harmless evenly to be filled on all angles, causes yield rate lower.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, provide a kind of yield rate, quality that has than long life and raising product also can improve the stepped diversion of production efficient, the large-size complex-cross-section mold of multi-stage diffluence.
The objective of the invention is to realize like this: the large-size complex-cross-section mold of a kind of stepped diversion, multi-stage diffluence, include upper die and lower die and die-cushion, said upper die and lower die and die-cushion are formed by stacking successively, and interfix through pin; Have a through hole in the middle of the said patrix feed end; Be provided with one-level shunting bridge, secondary shunting bridge and three grades of shunting bridges in this through hole, said one-level shunting bridge is arranged in the middle of this through hole, and said secondary shunting bridge is arranged at this through hole two ends; And the height of secondary shunting bridge is lower than one-level shunting bridge
Said three grades of shunting bridges are arranged on four angles of this through hole, and the height of three grades of shunting bridges is lower than secondary shunting bridge, and the discharge end corresponding position of said counterdie and patrix has die cavity one, and die cavity one corresponding section of said die-cushion and counterdie has die cavity two.
When producing extruding; Aluminium alloy gets into mould under the guide functions of one-level shunting bridge, one-level shunting bridge has played shunting action to aluminium alloy simultaneously, makes aluminium alloy evenly fill to all directions; Subsequently under the guide functions of secondary shunting bridge; Shunt once more, three grades of shunting bridges also carry out water conservancy diversion, shunting action to aluminium section bar subsequently, make being filled in the mould that aluminium section bar can be full and uniform.
The invention has the beneficial effects as follows:
Adopt multi-stage diffluence, stepped diversion technology; Metal flow is carried out multistage water conservancy diversion, reduced the flow resistance of a water conservancy diversion, guaranteed metal flowing evenly in mold cavity; Section bar yield rate and mechanical property have been improved; Reduce crush resistance simultaneously, improve die life, improved extrusion speed and production efficiency simultaneously.

(5) specific embodiment
Referring to Fig. 1 and Fig. 2, the present invention relates to a kind of stepped diversion, multi-stage diffluence large complicated section
The face mould tool includes patrix 1, counterdie 2 and die-cushion 3, and said patrix 1, counterdie 2 and die-cushion 3 are formed by stacking successively, and interfix through pin; Have a through hole in the middle of the feed end of said patrix 1; Be provided with one-level shunting bridge 101, secondary shunting bridge 102 and three grades of shunting bridges 103 in this through hole; Said one-level shunting bridge 101 is arranged in the middle of this through hole, and said secondary shunting bridge 102 is arranged at this through hole two ends, and the height of secondary shunting bridge 102 is lower than one-level shunting bridge 101; Said three grades of shunting bridges 103 are arranged on four angles of this through hole; And the height of three grades of shunting bridges 103 is lower than secondary shunting bridge 102, and said counterdie 2 has die cavity 1 with the discharge end corresponding position of patrix 1, and said die-cushion 3 has die cavity 2 31 with die cavity one 21 corresponding sections of counterdie 2.
Claims (1)
