Method for preparing integrated composite battery box shell based on mold compression stroke

The invention provides a method for preparing an integrated composite battery box shell based on a mold compression stroke, and belongs to the technical field of battery box shell forming. The method comprises the following steps: laying a fiber fabric and a functional material layer, and sequentially carrying out cutting treatment and connecting treatment to obtain a connecting material block; the connecting material block is placed in a pre-forming mold of a press I to be subjected to pre-pressing forming, and a pre-formed shell is obtained; the preformed shell is placed in a glue injection forming mold of a press machine II, the glue injection forming mold comprises an upper mold and a lower mold, a preset distance is formed between the upper mold and the upper surface of the preformed shell to form a mold cavity, forming resin liquid is injected into the mold cavity, then the press machine II is started for mold closing to conduct a compression stroke, and the preformed shell is formed; and then the mold
