Problems solved by technology

[0002] like figure 1 , in the actual production of aluminum alloy wheels, sometimes the forging blank of the wheel hub is relatively large, while the ejector rod of the lower die is relatively small (limited by the diameter of the hub riser and the front shape, it is impossible to increase the ejector rod of the lower die ), at this time, the ejection force of the ejector rod of the lower die on the blank is insufficient, and the blank cannot be ejected smoothly
It has brought difficulties to the normal production of the wheel hub

Embodiment Construction

[0010] like figure 2 , image 3 As shown, the existing lower die ejector rod 1 is replaced with the central lower die ejector rod 3, and the auxiliary lower die ejector rod 4 is added at the plane of the bolt hole boss on the front of the blank. The quantity of the auxiliary lower die ejector rods 4 to be increased is based on the quantity of the bolt hole bosses 5 of the blank. The ejector rods 3 of the central lower die and the ejector rods 4 of each auxiliary lower die are connected with the upper plate 9 of the ejector pin, the lower plate 8 of the ejector pin, the central clamping plate 7 and the auxiliary clamping plate 6 . The upper plate 9 of the push rod and the lower plate 8 of the push rod are connected with bolts 10 . The entire system is combined as a lower die ejector.

Abstract

The invention discloses a lower die ejector of a forging die, mainly comprising a central lower die ejector rod 3 and auxiliary lower die ejector rods 4, wherein the central lower die ejector rod 3 is connected with each auxiliary lower die ejector rod 4 by an ejector rod upper plate 9, an ejector rod lower plate 8, a central clamping plate 7 and an auxiliary clamping plate 6; and the ejector rod upper plate 9 and the ejector lower plate 8 are connected by a bolt 10. In the lower die ejector of a forging die, the ejection force to a forging blank is greatly increased through the addition of the auxiliary ejector rods, thereby smoothly ejecting relatively-large forging blanks out.

Description

technical field [0001] The invention relates to a die, in particular to a lower die ejector of a forging die for producing an aluminum alloy wheel hub. Background technique [0002] like figure 1 , in the actual production of aluminum alloy wheels, sometimes the forging blank of the wheel hub is relatively large, while the ejector rod of the lower die is relatively small (limited by the diameter of the hub riser and the front shape, it is impossible to increase the ejector rod of the lower die ), at this time, the ejection force of the ejector rod of the lower die on the blank is insufficient, and the blank cannot be ejected smoothly. Bring difficulty to the normal production of wheel hub. Contents of the invention [0003] The purpose of the present invention is to provide a device capable of smoothly ejecting the forging blank. [0004] The technical scheme of the present invention is: as figure 2 , image 3 As shown, the existing lower die ejector rod is repla...
