For addressing the above problem; As an aspect of the utility model, the mould of engineering plastics extruders is provided, comprising: patrix; Patrix comprises first compressional zone, first thermal insulation board and the first cooling forming district, and first compressional zone and the first cooling forming district are arranged on the both sides of first thermal insulation board respectively; First compressional zone is provided with first hole of heating; The first cooling forming district is provided with first cooling water hole; Counterdie, counterdie comprise second compressional zone, second thermal insulation board and the second cooling forming district, and second compressional zone and the second cooling forming district are arranged on the both sides of second thermal insulation board respectively; Second compressional zone is provided with second hole of heating; The second cooling forming district is provided with second cooling water hole; Middle plate, middle plate holder is between upper die and lower die.
Further, mould also comprises first plate and second plate, and first plate is arranged between patrix and the middle plate; Second plate is arranged between middle plate and the counterdie.
Further, first plate and/or second plate are corrosion resistant plates.
Further, patrix is provided with first groove, and counterdie is provided with second groove, and first thermal insulation board is arranged in first groove, and second thermal insulation board is arranged in second groove.
Further, first groove and second groove are arranged on corresponding position.
Further, mould also comprises two side plates, and the two ends of patrix, middle plate and counterdie are clipped between two side plates.
Separate with thermal insulation board respectively between the compressional zone of the upper die and lower die in the utility model and the cooling forming district, thereby reduced the temperature effect between compressional zone and the cooling forming district, thereby practiced thrift the energy, reduced cost, improved product quality.
