An upper mold core groove 11 is opened in the upper mold base 1, and an inner mold core block 6 is provided in the groove above the lower mold base 2, and an outer mold core block 5 is sleeved on the inner mold core block 6, so that the inner mold core block 6 and the outer mold core block 5 are fitted to prevent the injection liquid from entering between the two, which will cause the product part 9 to produce waste edges. The inner mold core block 6 and the outer mold core block 5 are inserted into the upper mold core groove 11 at the same time, so that the internal injection molding forms a product part 9. A convex mold is provided under the upper mold base 1 The raising ring block 4 is inserted into the groove ring portion 21 above the lower mold base 2 by using the raised ring block 4 to prevent the injection liquid from overflowing during injection molding to ensure that the internal product part 9 is completed without excess material. A straight push rod 8 is provided in the lower mold base 2, and the straight push rod 8 is inserted upward into the inner wall of the clamping groove 51 of the outer mold core block 5. When opening the mold, since the upper mold base 1 and the lower mold base 2 are both connected to the outside with a control component, the upper mold base 1 is disengaged first, and then the external control acts on the straight push rod 8, so that the straight push rod 8 pushes up, and the outer mold core block 5 and the product part 9 are simultaneously lifted to disengage the inner mold core block 6 and the lower mold base 2, and then the product part 9 is removed from the outer mold core block 5 by the outside, and the mold opening is completed.
