[0002] As an indispensable component of the extruder, the extrusion die plays an important role in the extrusion molding process. The extrusion die provided by the prior art often gets clogged during the production process and needs to be manually unblocked and cleaned, which greatly reduces the production efficiency. At the same time, due to the structural problems of the existing extrusion die, the blocked die needs to be manually unblocked using a drill, which is difficult and time-consuming, greatly affecting the production efficiency.

[0003] In the prior art, a Chinese invention patent with a patent application publication number of CN107283788A discloses an anti-clogging extrusion molding die head, which includes an extrusion die head, on which a molding die hole penetrating along its thickness direction is provided, and a heating anti-clogging mechanism is provided in the molding die hole; the heating anti-clogging mechanism is coaxially and detachably sleeved in the molding die hole, and the heating anti-clogging mechanism includes a heating core rod, and a mounting support sleeve for supporting the heating core rod and for mounting the heating core rod in the molding die hole; this technical solution effectively solves the clogging phenomenon of the extrusion die head by adding a heating anti-clogging mechanism to the traditional extrusion die head.

[0004] The above technical scheme reduces the frequency of cleaning the extruder head mold from the perspective of reducing the clogging of the extruder head mold to ensure production efficiency. However, the above scheme makes the structure of the extruder head mold more complicated and the manufacturing cost high.

As a result, the application of the above technical scheme is limited. Therefore, the technical concept of adding a heating anti-clogging mechanism cannot effectively solve the technical problem that the extruder head mold is difficult to clean after being blocked, affecting production efficiency.
