Multi-station jacking mold

Abstract

The invention discloses a die capable of ejecting materials at multiple stations, and belongs to forging dies. The die structurally comprises an upper die body, a lower die body, an upper die holder and a lower die holder. A material ejection mechanism is arranged on the lower portion of a cavity of the lower die body inside the lower die holder. The material ejection mechanism comprises middle ejection rods, side ejection rods, middle swing arms, side swing arms, swing arm shafts and equipment ejection rods. A swing arm cavity is arranged in the middle position of the lower portion of the lower die holder, the number of the swing arm shafts is two, and the swing arm shafts are arranged at the front end and the rear end of the swing arm cavity of the lower die holder. Each swing arm shaft is provided with one middle swing arm and one side swing arm, each middle swing arm is provided with one middle ejection rod, each side swing arm is provided with one side ejection rod, and the equipment ejection rods are arranged on the lower portions of the two middle swing arms. The middle ejection rods and the side ejection rods are each of a two-stage segmented structure. The die capable of ejecting materials at the multiple stations has the advantages that the demand for center part material ejection can be met, material ejection at multiple stations within a certain range can also be achieved, the technology ejection requirements of different types of products can be met, and the application range is wide.

Description

technical field [0001] The invention relates to a forging die, in particular to a multi-station jacking die applied to a friction press. Background technique [0002] The ejecting mechanism of the friction press is set at the center of the workbench, and there is only one ejecting station, which can only eject materials at the center. Therefore, it is usually only suitable for the final forging and ejecting of rotary bodies or symmetrical products, but in In the actual production process, there are many kinds of products and different process requirements. It is often encountered that pre-forging is required or the material cannot be ejected from the core due to product structure. Therefore, this ejecting method of the friction press has the advantages It has great limitations and cannot meet the process requirements of some products. [0003] Currently, there is no good solution. Contents of the invention [0004] The technical task of the present invention is to provid...
