Abstract

The utility model discloses a hanging-free plastic extruder die head. The hanging-free plastic extruder die head comprises a left die body, a right die body, die body screws, a left die lip body, a right die lip body, die lip body fastening screws and die lip body adjusting screws, wherein the left die lip body and the right die lip body are mounted on the left die body and the right die body; a gap is designed between the left die lip body and the right die lip body; two die lips on the lower part of the gap are designed into inclined planes or cutter points; when a smelt is extruded from the die lips, part of impurities in the smelt can be sprayed out while being extruded and expanded and can find hanging points; the two die lips on the lower part of the gap are designed into the inclined planes or the cutter points and have high glossiness, so that the sprayed-out impurities have no hanging fields and are brought away by the smelt at any time; therefore, a die opening is prevented from being hung with burnt materials or scorched materials. The hanging-free plastic extruder die head has the beneficial effects that the defects that the die opening is hung with the burnt materials or the scorched materials can be overcome effectively and the working efficiency is improved greatly; the electricity is saved and raw materials are saved; the economic benefits of enterprises are improved, and the labor environment is improved greatly and the labor intensity of a worker is relieved.
