A bottom-injection turbocharger turbine wax mold molding die includes: a mold base plate with a first cooling medium channel and a second cooling medium channel; an end insert, one axial end of which has an irregular end structure, and the other axial end of which is fixedly connected to the mold base plate; and a gate insert assembly, including a tubular outer sleeve, which is sealed between the inner hole of the end insert and the mold base plate. An inner tubular component is inserted through the outer sleeve, and the outer wall of the inner tube has a groove. The groove and the inner wall of the outer sleeve enclose a third cooling medium channel, which connects the first and second cooling medium channels. The inner hole of the inner tube serves as a wax injection channel. The cooling medium cools the wax in the wax injection channel to form a wax rod, thereby increasing the cooling speed of the gate insert and ensuring good connection between the wax rod and the wax mold, while improving production cycle time and ensuring production continuity.
