During use, the working surface of the upper mould and the surface of the lower die cavity are prone to wear, while other parts are intact, resulting in a relatively high use cost. Its solution is this split plate forming mould. Through the detachable design of the upper die base and the lower die base with the upper die core and the lower die core respectively, it can well avoid the situation where the key parts of the mould are worn and cannot be replaced. Through the cooperation of the upper die core, the lower die core, the limit stud, the first limit block and the second limit block, the replacement of the key parts of the mould can be well realized, avoiding the situation of relatively high use cost. Through the setting of the unloading spring and the blanking plate between the first forming die and the second forming die, the workpiece can be well unloaded, reducing the time required for unloading and greatly improving the work efficiency.
