Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only part of the embodiments of the present utility model, not all implementations. example. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

Please refer to Figures 1-4. The present utility model provides a technical solution: a unloading device for a hydraulic press, including a mounting plate 1. A hydraulic rod 2 is fixed at the lower end of the mounting plate 1, and the lower end of the hydraulic rod 2 is fixed on the mounting plate.
