The invention discloses that the invention provides a PEKK powder hot-press molding mold and molding method based on a universal testing machine, including an upper template, a lower template, a convex mold, a concave mold, heat insulation cotton, support columns, fastening bolts, pads Chips, nuts, set screws, heating rods, thermocouples, high-precision temperature PID controllers, solid-state relays, temperature control circuits, and PEKK powder to be formed. The fastening bolts pass through the upper formwork, support columns, punches, mating gaskets and nuts to connect the upper mold part; due to the weight of the lower mold part, the fastening screws pass through the lower formwork, supporting columns, die and mating gaskets to connect the lower mold Insert the thermocouple and heating rod into the corresponding holes, and fix their positions with set screws; connect the temperature PID controller and solid state relay, and connect the heating rod and thermocouple into the circuit control system; finally connect the upper mold part into the upper chuck of the testing machine, and the lower mold part is connected to the lower chuck of the testing machine.
