The invention provides an injection molding upper and lower end type cavity structure comprising an injection molding flow pass and an injection molding piece cavity, the injection molding piece cavity is provided with an injection molding groove, and an injection molding port of the injection molding flow pass extends to the injection molding groove. The injection molding groove is arranged at a combination part of the injection molding piece cavity and the injection molding port of the injection molding flow pass, so that after an injection molding piece is taken from the injection molding piece cavity, the combination part of the injection molding piece and the injection molding flow pass is remained in the injection molding groove, when the combination part connected with the injection molding piece and the injection molding flow pass is removed, a burr structure formed on the injection molding part by the combination part is remained in the injection molding groove, and during a use process of the injection molding piece, burrs are ensconced by the injection molding groove, so that a user can avoid injuries caused by the burrs. The present invention also provides an upper and lower end injection mould with the injection molding upper and lower end type cavity structure.
