Injection mould of clamping cover of shaft hole of dustbin

The invention discloses an injection mould of a clamping cover of a shaft hole of a dustbin. The injection mould comprises a female mould body (1), wherein a guide rod (2) matched with a male mould guide hole in an inserting manner is arranged at one end of the upper top surface of the female mould body (1) in a mirror image manner, a guide hole (3) matched with a male mould guide rod in an inserting manner is formed in the other end of the upper top surface of the female mould body in a mirror image manner, a butt joint step surface is inwards milled in the middle of the female mould body (1), a casting riser groove (4) is inwards milled in the middle of the butt joint step surface, one circle of clamping cover cavities (5) are arrayed annularly outside the casting riser groove (4), and are connected with the casting riser groove (4) by virtue of casting channels (6), and a casting hole (7) is formed in the casting riser groove (4). The injection mould is simple in structure and convenient to use; a plurality of clamping covers can be processed once, and thus the whole yield is improved, and the whole cost is lowered; when the injection mould is used, the shaft hole is covered by the injection mould directly, and thus the phenomenon of internal matching failure caused by blockage of dirt is effectively prevented.
