Secondary color adjustment-free machine head outer mold sleeve of wire extruder

Abstract

The invention discloses a secondary color adjustment-free machine head outer mold sleeve of a wire extruder and belongs to the technical field of wire and cable extruding devices. The secondary coloradjustment-free machine head outer mold sleeve of the wire extruder comprises an outer mold sleeve body. A mold core cavity penetrating one end of the outer mold sleeve body to the other end is formedin the center of the outer mold sleeve body. A color masterbatch feeding groove and a diversion groove are formed in the outer wall of the outer mold sleeve body. The color masterbatch feeding groovecommunicates with the diversion groove, the diversion groove communicates with a diversion opening, and the diversion opening communicates with the mold core cavity. The secondary color adjustment-free machine head outer mold sleeve of the wire extruder is characterized in that the diversion opening is formed in the wall of the left end of the outer mold sleeve body and is in a circular arc cavity structure with peripheral fence. Color masterbatch passing through the diversion opening can be effectively controlled, and the change of different widths of color strips is avoided. It is ensured that the boundary of a secondary color material and a main color material is clear. The situation that the color masterbatch is blindly wasted is avoided. The quality of a secondary color cable is improved.

Description

technical field [0001] The invention belongs to the technical field of wire and cable extruding devices, and in particular relates to an outer mold cover of a color-free extruding machine head of a wire extruding machine. Background technique [0002] The aforementioned wire extruder is a cable extruder or a cable sheath extruder. The typical example of the above-mentioned non-toning and intercoloring machine head is the U7 non-toning and intercoloring machine head. Since the concept, function and working principle of the U7 non-toning and intercoloring machine head belong to the known technology and can also be seen in the published Chinese patent documents, As CN203600587U recommends "a wire extruder U7 intermediate color head outer mold cover", so the applicant will not expand the description. [0003] Figure 5 It is a structural diagram of the outer mold cover of the single-color and color-free machine head generally used in the prior art, including the outer mold cove...

However, by reading the full text of its specification and combining the relevant figures, it can be seen that since the diversion port of the color masterbatch channel, that is, the discharge port, is in an unregulated and tending to open state, it is processed by the cable single-wire die sleeve of the patented structure. The above-mentioned color bar will also appear Figure 5 and Figure 7 lack of
