Abstract

The invention discloses a double-layer three-color electric wire extruding machine head in the field of electric wire production equipment, which comprises a machine head body, the machine head body is connected with a die sleeve, a shunting cavity extending to the middle part of the die sleeve is arranged in the machine head body, the machine head body on one side, deviating from the die sleeve, of the shunting cavity is connected with an end cover, the shunting cavity is conical, and a conical outer shunt is inserted in the shunting cavity; an outer flow divider is arranged on the surface of the machine head body, an outer branch runner is formed in the surface of the outer flow divider, a conical inner flow divider is inserted into the outer flow divider, an inner branch runner is formed in the surface of the inner flow divider, a mold core is inserted into the end, located in the mold sleeve, of the inner flow divider, a wire passing channel is formed in the mold core, and a middle feeding port communicated with the outer branch runner is formed in the side end of the machine head body. A large feeding hole communicated with the inner sub-runner is formed in the top of the machine head body; and a small feeding hole communicated with the wire passing channel is formed in the side end of the die sleeve. The double-layer three-color environment-friendly electric wire can be produced, and the problem that a matched extrusion machine head for producing the double-layer three-color environment-friendly electric wire is lacked in the prior art is solved.

Description

technical field [0001] The invention relates to the field of electric wire production equipment, in particular to a double-layer three-color electric wire extrusion head. Background technique [0002] Ordinary environmentally friendly wires are generally extruded from a single environmentally friendly insulating material in an extruder to form a single-layer single-color insulated environmentally friendly wire. The colors are red, yellow, blue, green, etc. The head die extrudes wires of a single color. Conventional double-layer double-color environmental protection wires generally use two extruders to extrude insulating materials. The inner layer insulation is of natural color, and the outer layer insulation is of different colors. Two extruders cooperate with double-layer molds to extrude wires of two colors. Existing a kind of double-layer three-color environment-friendly electric wire has inner layer insulation of natural color and outer layer insulation of two colors (y...
