MOLD FOR MANUFACTURING ELECTROFUSION JOINT

PROBLEM TO BE SOLVED: To provide a mold for manufacturing an electrofusion joint capable of preventing generation of breakage such as disconnection at a connection part between a terminal pin and an electric heating wire along with mold installation work as well as capable of improving working efficiency. SOLUTION: The mold B is composed of a rod-shaped inner mold 16 and a cylindrical outer mold 17. The mold B includes a pin insertion hole 16c and also includes an engagement part 18 on the other end 16b side to form the inner mold 16. The mold B includes an engagement receiving part 20 at an inner hole part positioned on the other end 17b side from an injection space forming part 19 to form the outer mold 17. The inner mold 16 is installed by inserting the terminal pin 3 into the pin insertion hole 16c. In a state that the outer mold 17 is installed by engaging the engagement part 18 with the engagement receiving part 20, mutual axes O1, O2, O5 of the terminal pin 3, of the inner mold 16, and of the outer mold 17 are arranged on the same axis, while an injection space H is formed between an outer peripheral surface of the inner mold 16 and an inner peripheral surface of the outer mold 17.
