The utility model discloses an injection mould for high stability pipe fittings, which comprises an upper die, a lower die and an elastic core barrel. The elastic core barrel is connected in the lower die. The upper die is clamped on the lower die. The cavity structure between the elastic core barrel and the upper die and the lower die is a forming cavity. The upper end of the elastic core barrel is connected with a top plate. The lower end of the upper side wall of the upper die has a top plate groove, and the top plate is clamped into the top plate when forming. In the groove, the inner part of the elastic core tube is the core cavity, and the lower end of the lower side wall of the lower die is connected with the intake pipe, the cooling water intake pipe and the cooling water outlet pipe. The intake pipe, the cooling water intake pipe and the cooling water outlet pipe pass through the lower side wall of the lower die and are connected with the core cavity. The utility model has the advantages that the hollow core barrel structure can be used as the core mould when the gas is inflated, and the core barrel can be contracted when the gas is released, so that the demoulding can be carried out conveniently; the top of the core barrel is connected with a roof to avoid irregular deviation of the core barrel; the cooling water inlet and outlet is provided, which can quickly cool the formed pipe diameter in the mould, and greatly improve the production efficiency.
