Abstract

The invention provides a novel silicon rubber line extrusion die sleeve. The novel silicon rubber line extrusion die sleeve can discharge mixed impurities, maintain extrusion production and extrusionperformance and guarantee the aesthetic property and quality of products in the cable extrusion process. The novel silicon rubber line extrusion die sleeve comprises a die core connecting part and a double-nut connecting part, and is characterized in that an inner cavity of the die core connecting part is conically closed up; a center hole is formed in the center of the double-nut connecting part;the center hole is used for matched mounting of a die core boss; a discharge groove extending in the length direction of the die sleeve is formed in the radial position of the outer ring surface of the double-nut connecting part and the die core connecting part; the discharge groove is sunken inwards in the corresponding position of the outer ring surface of the die core connecting part and the double-nut connecting part; the discharge groove covers the whole length of the whole die sleeve in the length direction; and during mounting, the discharge groove is aligned with the glue line combination portion of a machine head.

Description

technical field [0001] The invention relates to the technical field of silicone rubber thread extrusion, in particular to a novel silicone rubber thread extrusion die sleeve. Background technique [0002] During the silicone rubber mixing process or due to the aging of the extrusion equipment, the silicone rubber has been rubbed into the screw barrel for a long time and mixed with impurities that are not compatible with the silicone rubber, and the surface of the extruded tubular silicone rubber is covered with a layer of impurities at the head. After the conventional mold is placed, a line will appear in the extruded cable, which not only affects the appearance of the cable, but also has an unpredictable negative impact on the wire and cable. Contents of the invention [0003] In view of the above problems, the present invention provides a new type of silicone rubber wire extrusion die sleeve, which discharges the mixed impurities during the cable extrusion process, and m...
