Integral threaded plastic rope extrusion mould

Abstract

The invention discloses an integral threaded plastic rope extrusion mould which comprises a hollow cylindrical guide barrel and a hollow cylindrical extrusion barrel, wherein the guide barrel comprises a first smooth inner wall; the extrusion barrel comprises a second inner wall with a spiral groove inside; a positioning groove opening is formed in the head of the guide barrel. According to the integral threaded plastic rope extrusion mould, plastic particles can be re-arranged and extruded after entering the mould by the first smooth inner wall and the second inner wall with the spiral groove inside, so that air entering the mould is greatly reduced, pores in a plastic rope are effectively reduced, and the quality of the threaded plastic rope is effectively improved. The integral threaded plastic rope extrusion mould is simple in structure, convenient to reform and high in practicality.

Description

technical field [0001] The invention relates to an extrusion processing device, more precisely, an integral threaded plastic rope extrusion die. Background technique [0002] Threaded plastic rope is a new type of rope extruded from polymer materials, with anti-slip threads on the surface. Compared with traditional braided ropes, the manufacturing cost is lower and the strength is the same. When the existing threaded plastic rope is extruded, the plastic granules directly enter the cylindrical mold. Since the entire section of the mold is threaded, the granules are immediately squeezed when they enter, and it is easy to mix air, which is easy to get inside the rope. The formation of pores affects the quality of the threaded plastic rope. Contents of the invention [0003] The invention mainly solves the technical problems existing in the prior art, thereby providing an integral threaded plastic rope extrusion die. [0004] Above-mentioned technical problem of the present...
