Bidirectional pressing forming mould used for unidirectional press

The utility model aims at solving the technical problems of low production efficiency, discontinuous pressing process and low pressing forming quality of traditional formed moulds. In order to solve the above problems, a bidirectional pressing forming mould used for a unidirectional press is provided. The bidirectional pressing forming mould comprises a mould cavity, wherein the mould cavity is provided with an upper pressing head and a lower pressing head therein, the mould cavity is arranged on a movable backing plate; a middle part of the movable backing plate is provided with a fixing sleeve core corresponding to the lower pressing head, the movable backing plate is provided with an elastic body corresponding to the mould cavity therein. According to the bidirectional pressing forming mould of the utility model, the movable backing plate is adopted, and a lower sizing block needs not to be removed, thus synchronous and continuous process of bidirectional pressing can be well ensured, at the same time, forming uniformity of a product is effectively realized, forming process is reduced, and efficiency of labor is raised, thus the bidirectional pressing forming mould of the utility model has extremely high economic benefit and practical value.
