Abstract

The invention discloses a multi-material-channel extrusion die. The multi-material-channel extrusion die comprises a fixed box body, an extrusion head component, material extrusion rods and a wall thickness adjustment component, wherein the extrusion head component comprises a fixed cover plate, extrusion end covers and adjustment wedges; the wall thickness adjustment component comprises extrusionnozzle adjustment rods and a power mechanism; a plastic blank is extruded from a feed port of the fixed box body and extruded out from extrusion ports of the extrusion end covers through extrusion channels formed by the fixed box body, the extrusion end covers and the material extrusion rods; the extrusion effect is adjusted by adjusting the positions of the extrusion end covers through the adjustment wedges; and the wall thickness of an extrusion bottle preform is adjusted by controlling the extrusion nozzle adjustment rods through the power mechanism. The multi-material-channel extrusion die is compact in structure and strong in practicability, and is suitable for continuous extrusion molding production. The multi-material-channel extrusion die can be applied to the field of plastic product production.

Description

technical field [0001] The invention relates to the field of plastic product production, in particular to a multi-channel extrusion die head. Background technique [0002] The function of the extrusion die is to make the plastic melt from the extruder barrel well distributed in the flow channel of the die, so that it can be extruded and formed from the die at a uniform speed. The forming function of the extrusion die is crucial in the extrusion process. [0003] Common types of extrusion dies are single-stream and multi-stream. Especially in the production of plastic bottles, molding molds with multiple molding cavities are often used. This kind of multi-form blowing mold needs to use the corresponding multi-channel extrusion die to extrude the preform for feeding. . In the multi-channel extrusion die head in the prior art, it is difficult to debug multiple outlets of the die head, and the molding is often caused by the docking error between the multiple outlet channels o...
