Wherein, the movable mold has a plurality of second arc surfaces, and the plurality of second arc surfaces are symmetrically arranged on the movable mold.

A die-casting mold clamping force enhancement mechanism of the present invention. When using a die-casting mold, before the movable mold and the fixed mold are closed, the clamping block is first opened on the locking block. After the mold is closed with the fixed mold, the clamping block is slid towards the locking block, the clamping block is closed with the locking groove on the guide post, and the guide post is locked on the locking block. The block is locked. When opening the mold, the clamping block is opened, the guide post is unlocked, and the mold is opened. By designing the guide post of the mold to be a bolt structure, the guide post hole can pass through The opening/closing hydraulic control nut structure realizes the opening and closing of the clamping block in the locking block, achieving a tight connection between the fixed mold and the movable mold, enhancing the clamping force, and achieving good use effect of the mold.
