[0020] In order to make the above features and advantages of the utility model more obvious and easy to understand, the following embodiment is taken, and the detailed description is as follows in combination with the drawings.

[0021] As Figures 1-5As shown, a kind of string bead rope sheath shaping mould, including lower mould 1, the lower mould upper end face is concave and has lower mould cavity 2 downwards, the lower mould cavity extends along the length direction of lower mould and end face is semicircular arc, the lower mould cavity is spaced and is provided with several mould cavities 3 for placing string bead, the lower mould cavity on both sides of the mould cavity is protruded with several positioning blocks 4, the lower mould cavity between two adjacent mould cavities is protruded with anti-deviation top block 6 on the side away from injection port 5, the injection port includes injection slot 7 and interval setting in the injection slot and lower mould cavity to connect the both of separate injection slot 8.

[0022] In the embodiment of the utility model, the lower mould upper cover is equipped with the upper mould 9 which is symmetrically arranged above and below with the lower mould except the separate injection slot, and the separate injection slot of the upper mould is staggered with the separate injection slot of the lower mould.

[0023] In the embodiment of the utility model, the anti-deviation top block is arc-shaped and protrudes inward from the upper edge of the lower mould cavity and extends downward along the inner wall of the lower mould cavity in an arc shape.

[0024] In the embodiment of the utility model, the positioning block is provided with three groups and is spaced and arranged on the arc surface of the bottom of the lower mould cavity, and the central axis of the positioning block is directed to the center of the lower mould cavity.
