Closed type water seepage and drainage pipe forming die

The utility model relates to a closed type water seepage and drainage pipe forming die which comprises a horizontal supporting die plate and two symmetrically-arranged side die plates located on the supporting die plate, a bottom plate groove is formed in the upper end face of the supporting die plate, the two side die plates and the bottom plate groove form a die cavity after die assembly, and the closed type water seepage and drainage pipe forming die further comprises two core shafts inserted from the two ends of the die cavity. A plurality of inverted U-shaped grooves communicated with the bottom plate groove are formed in the inner sides of the side mold plates, the mold plate driving mechanism is used for driving the two side mold plates to be opened and closed synchronously, and the core shaft driving mechanism is used for driving the two core shafts to be inserted and pulled synchronously. A pipe body of the water seepage and drainage pipe is formed on the outer side of the core shaft, so that one-tim
