This utility model provides a tooling for irregularly shaped ring forgings for automotive wheel hubs, belonging to the field of automotive wheel hub processing technology. It includes a lower die base and a pressure plate. A lower die is fixedly mounted on the top of the lower die base. An upper die base is connected to the bottom of the pressure plate via a first elastic element. Two upper dies are slidably mounted on the bottom of the upper die base, facing each other and separated from the upper die base by a second elastic element. Two fixing blocks are fixedly mounted on the top of the lower die base, each corresponding to one of the upper dies. Each fixing block is driven and engaged with its corresponding upper die via a first transmission element. Two mating blocks are fixedly mounted on the pressure plate, both corresponding to the fixing blocks in a limited sliding engagement and being driven and engaged with their corresponding upper dies via a second transmission element. In this application, the closing and opening of the two upper dies are completed during the up-and-down movement of the pressure plate, eliminating the need for separate adjustments, making operation more convenient and increasing automation.

The utility model discloses a crystal processing mould with push-out and pull-back functions, which comprises an open shell (1) and a plurality of mould blocks, each mould block is connected in the shell (1) in a sliding manner, a push-pull piece (2) is arranged on the inner bottom surface of the shell (1), and the push-pull piece (2) is connected with the bottom end parts of all the mould blocks in a sliding and clamping manner; the push-pull piece (2) pushes all the mold blocks out of the shell (1) and pulls all the mold blocks back to the shell (1) at the same time. The device is convenient to operate, and has the advantages of high working efficiency, simple structure, good forming effect and high structural stability.
