Abstract

The forming die set is composed of a die, a die sleeve and a splitter. There are inner screws on two ends of die sleeve in use for connecting to the die and the splitter. Through outer screw, the die sleeve is connected to the plastic extruding machine. Being in shape corresponding to cross sectional shape of cable padding strips, the shaped orifice is made on the end face of the die, and the shaped orifice is with obliquity. The splitter consists of diversion pole, diffluence disk, and diversion cone. The diversion pole and cone are on left and the right of the disk respectively. Multiple feed orifices are made on end face of the disk evenly. Since the die, the die sleeve and the splitter are in a separated structure, thus, the die is possible to be designed in laminar structure. Therefore, the shaped orifice with obliquity is easy to be manufactured. The splitter makes materials flow reasonably in thermal forming procedure. Thus, the invention raises yield of finished product.

Description

Technical field: [0001] The invention relates to a plastic molding die, in particular to an extrusion molding die for cable filling strips. Background technique: [0002] In the production process of cable filling strips, extrusion molding molds must be used. At present, the molds used are direct molding dies. The plastic is not evenly distributed during the molding process, and defects such as incomplete strips and lack of materials are easy to occur. Cable filling The yield rate of strips is not high, and the stability of quality is not guaranteed. Invention content: [0003] The object of the present invention is to provide a cable filling bar extrusion molding die. [0004] The cable filling strip extrusion molding die of the present invention is composed of a forming die, a die sleeve and a shunt. The two ends of the die sleeve are provided with inner screw holes connecting the molding die and the shunt. The forming die is installed on the inner screw at the right en...
