The utility model provides an injection molding process mold for monitoring the pressure in a mold cavity, which relates to the technical field of monitoring the pressure in the mold cavity and comprises a mold, sinking grooves are respectively formed in the centers of the inner surfaces of the periphery of the mold, and hydraulic rods are respectively and fixedly connected to the centers of the outer surfaces of the periphery of the mold; guide rods are slidably connected to the center of the outer surface of the periphery of the mold in a penetrating mode, through holes are formed in the positions, located on the guide rods, of the outer surface of the periphery of the mold, and an L-shaped plate is slidably connected between the opposite inner surfaces of a sinking groove. The pressure sensor generates readings, a part of plastic is located in the connecting piece after curing, the hydraulic rod shrinks to drive the L-shaped plate to move, then the connecting piece moves synchronously, the cured plastic is
