The invention discloses a precision injection mold, which comprises an upper mold, a lower mold, a heating rod, a bolt hole, a positioning hole, a telescopic column, a baffle, a buffer layer, a damping spring, an asbestos layer, perforations, a lower mold cavity, and an upper mold Cavities, limit posts, coil springs, fastening bolts, connecting plates, top plates, bottom plates and mounting holes. The beneficial effects of the present invention are: by connecting the baffles on both sides of the upper mold and the lower mold, and filling the elastic buffer material between the two mold bodies and the baffles, and installing shock-absorbing springs and telescopic columns, the working baffles The two phantoms can be protected from damage. During transportation or handling, when the mold collides or is squeezed, the two mold bodies and the mold cavity inside are not easily damaged and deformed, ensuring that the mold can work safely and efficiently without easily affecting its precision. The injection mold is convenient and quick to install, saves energy, and has high work safety performance and precision performance.
