Abstract
The utility model discloses a backward extrusion mould storage silo, including the upper die base, with upper die base matched with die holder, the last mold core that has of upper die base, the mold core has down on the die holder, go up the mold core with form the shaping chamber of product between the lower mold core, forging body storage silo has been seted up on the lower mold core, forging body storage silo is linked together with the die parting face, the projection of forging body storage silo on the horizontal plane with the projection of the lower terminal surface in shaping chamber coincides mutually on the horizontal plane, and convenient follow-up side cut avoids the burr height to surpass forging body surface, need not the back end process of polishing.
Description
Technical Field
The utility model relates to a backward extrusion mould storage silo.
Background
The die forging of long rod products generally adopts an upsetting or forward extrusion forming mode, the material utilization rate and the yield are low, and the upsetting ratio is out of the range or the rod part is not punched enough. The reverse extrusion storage can not be realized and is difficult to follow-up no burr side cut, leads to adopting the process of polishing burring, and the cost of labor is high, and is efficient.
SUMMERY OF THE UTILITY MODEL
The utility model aims to overcome the defect that exists among the prior art, provide a backward extrusion mould storage silo, convenient follow-up side cut avoids the burr highly to surpass forging body surface, need not the later process of polishing.
In order to realize the above purpose, the technical scheme of the utility model a backward extrusion mould storage silo is provided, including the upper die base, with upper die base matched with die holder, the upper die core has on the upper die base, the die holder is gone up to have lower die core, go up the die core with form the die cavity of product down between the die core, forging body storage silo has been seted up on the die core down, forging body storage silo is linked together with the die parting face, the projection of forging body storage silo on the horizontal plane with the projection of the lower terminal surface in die cavity is coincided mutually.
The utility model has the advantages and the beneficial effects that: for die forging products, polishing is not a normal manufacturing process, and only aims to meet the project and customer requirements that die forging cannot be completed.
Drawings
Fig. 1 is a schematic view of the present invention.
Wherein: 1. an upper die holder; 2. a lower die holder; 3. an upper mold core; 4. a lower mold core; 5. a molding cavity; 6. forging body storage silo.
Detailed Description
The following description will further describe embodiments of the present invention with reference to the accompanying drawings and examples. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1, the storage bin of the backward extrusion die comprises an upper die holder 1 and a lower die holder 2 matched with the upper die holder 1, wherein an upper die core 3 is arranged on the upper die holder 1, a lower die core 4 is arranged on the lower die holder 2, a forming cavity 5 of a product is formed between the upper die core 3 and the lower die core 4, a storage bin 6 of a forging body is arranged on the lower die core 3, the storage bin 6 of the forging body is communicated with a die parting surface, and the projection of the storage bin 6 of the forging body on the horizontal plane coincides with the projection of the lower end surface of the forming cavity 5 on the horizontal plane.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of improvements and decorations can be made without departing from the technical principle of the present invention, and these improvements and decorations should also be regarded as the protection scope of the present invention.
