Large-length-width-ratio plastic part mold with built-in demolding driving mechanism

The utility model provides a large-length-width-ratio plastic part mold with a built-in demolding driving mechanism, and belongs to the technical field of molds. The die comprises an upper die plate and a lower die plate, a forming insert is arranged on the lower die plate, the forming insert and the upper die plate are combined to form a forming cavity, a lossless ejection block structure matched with the forming cavity is arranged on the forming insert, and a bottom plate is arranged on the lower side of the lower die plate. The lossless ejection structure can prevent an injection molding part from being damaged when the injection molding part with the large length-width ratio is subjected to injection molding, the demolding driving assembly can drive the lossless ejection structure to move upwards to eject a product, the multi-point injection molding structure can inject injection molding liquid into a molding cavity through multiple points, the injection molding efficiency can be effectively improved, and
