Injection mould

The invention provides an injection mould comprising a lower mould seat and an upper mould seat arranged above the lower mould seat. The upper mould seat can move relative to the lower mould seat so as to conduct product injection. The injection mould further comprises sliding blocks slidably arranged on the lower mould seat, a driving mechanism arranged between the upper mould seat and the sliding blocks, lifters contained in the sliding blocks, power bearing parts arranged on the lifters, power transmitting parts arranged on the sliding blocks and guiding parts arranged on the lower mould seat. According to the injection mould, an inverted buckled structure of the side face of a workpiece can be formed in mould assembly injection, power used for movement of the lifters is provided by the upper mould seat, the mould structure can be simplified, and the stability of the mould is improved; and meanwhile, through arrangement of the guiding parts, it is also ensured that the workpiece can be separated from the m
