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:
The present invention relates to a kind of mould for plastics, relate in particular to the extrusion molding dies of cable filler strip.
Background technology:
In the production process of cable filler strip, must use extrusion molding dies, currently used is that mould is a straight forming mouth mould, plastics are shunted inhomogeneous in forming process, easily produce billot complete, lack defective such as material, the rate of finished products of cable filler strip is not high, quality of stability is guarantee not.
Summary of the invention:
Goal of the invention of the present invention provides a kind of cable filler strip extrusion molding dies.
Cable filler strip extrusion molding dies of the present invention, form by shaping mould, die sleeve and shunt, be provided with the inner bolt hole that connects into pattern and shunt at the two ends of die sleeve, shaping mould is installed in the inner bolt hole of die sleeve right-hand member, shunt is installed in the inner bolt hole of die sleeve left end, left end at die sleeve also is provided with external screw thread, and this screw thread links to each other with plastic extruding machine; Be provided with external screw thread on the cylindrical of shaping mould, offer with cable filler strip on its end face and cut and the corresponding moulding of shape hole, the moulding pore area is gradient, and import is big, goes out young; Shunt is made up of diversion column, shunting disk and guiding cone, and diversion column is provided with the left end of shunting disk, and guiding cone is arranged on the right-hand member of shunting disk, establishes the shunting external screw thread on the cylindrical of shunting disk, is provided with a plurality of charging holes on the end face of shunting disk equably.
Because the cable filler strip extrusion molding dies is designed to split formula structure, be integral by being threaded between shaping mould, die sleeve and the shunt, shaping mould is designed to laminated structure, and the moulding hole of offering on it that has gradient is convenient to make; Shunt can make raw material flow distribution in the thermoforming process more reasonable, and the combination of diversion column, shunting disk and guiding cone can improve the product qualified rate of cable filler strip.
