Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the present invention, "a plurality" means two or more unless otherwise specified.

Generally, when a fixed mold plate of an injection molding machine is stressed, the position of the front surface of the mold plate, which is in contact with a mold, is stressed by the mold in the direction from the front surface of the mold plate to the back surface of the mold plate, and the position of a guide post hole in the back surface of the mold plate is stressed in the direction opposite to the pressure direction of the mold. In order to reduce the weight of the mold plate and enable the mold plate to have sufficient strength, please refer to fig. 1-3, the utility model provides a fixed mold plate of an injection molding machine, which comprises a top plate 1, a reinforcing rib 2 and a bottom plate 3 which are sequentially stacked, wherein a plurality of cavities which are symmetrically distributed along the center of the fixed mold plate are formed among the top plate 1, the reinforcing rib 2 and the bottom plate 3, a charging barrel inlet hole 12 for a charging barrel of an injection molding injection platform to pass through is arranged in the center of the top plate 1, a mold positioning hole for determining the position of a mold is arranged on the bottom plate 3, and the charging barrel inlet hole 12 is communicated with the mold positioning hole.
