Hot upsetting die and upper die thereof

Abstract

The invention provides a hot upsetting die and an upper die thereof. The hot upsetting die comprises the upper die and a lower die, wherein the lower die comprises a lower die core component; the upper die comprises an upper die sleeve; an upper die core component is assembled in the upper die sleeve along the up-down direction in a guide moving way; an ejector pin is arranged in the upper die sleeve; a spring which applies an acting force for forcing the upper die core component to downwards move, so that the upper die core component is butted with the lower die core component to form a closed formed cavity before the ejector pin stamps a workpiece, is arranged in the upper die sleeve; the ejector pin and the upper die core component are assembled along the up-down direction in a guide moving way; the upper end of the spring presses against the ejector; the lower end of the spring presses against the upper die core component; the ejector presses against and is assembled on a die cushion which is fixedly arranged on an upper die holder under the action of the spring; during die stripping, the ejector pin moves upwards along with the upper die holder, and the upper die core component moves downwards under the action of the spring, so that the ejector pin can be quickly separated from the stamped workpiece, and the die stripping is favorably realized.

Description

technical field [0001] The invention relates to a hot heading die and an upper die thereof. Background technique [0002] With the rapid development of domestic aviation, aerospace and other fields, and the continuous advancement of science and technology, there are more and more products that require hot heading of upper and lower molds. The traditional processing scheme needs to be improved in terms of quality, cost, and safety to achieve resource utilization. Full utilization, strict quality and cost saving. In order to fully reflect the value of molds, the research and development of molds has become a top priority. [0003] Traditional hot heading dies such as figure 1 As shown, it includes an upper mold and a lower mold. The upper mold includes an upper mold core assembly, and the upper mold core assembly includes an upper mold core 103 and an upper mold core sleeve 104 that are fixedly assembled together. The upper mold base 101 is fixedly assembled together. The u...
