Abstract

The invention provides a die mechanism which can online detect pull-extrusion traction force, and a pull-extruder thereof, belonging to the field of the pull-extrusion forming equipment of composite material; wherein, a traction mechanism consists of a first traction mechanism and a second traction mechanism; a thermoplastic forming die part is provided with a pull-extrusion die which is clamped by a die pressing clamp; a guideway structure is arranged between a die workbench plate and a frame; the reasonable arrangement of the die mechanism can realize online detecting the traction force; the composite material dual-head pull-extruder of the invention is provided with the first traction mechanism and the second traction mechanism; the first thermoplastic forming die mechanism and the second thermoplastic forming mechanism form two paths of pull-extrusion lines which commonly share a felt-supply yarn-passing mechanism, the structure of a yarn-supply mechanism and a middle frame; therefore, the land occupying area of the equipment is effectively saved and the production efficiency of the equipment is improved; a glue trough at a dipping part is smartly designed, thus being more beneficial for the distribution of water flow in the interlayer of the trough bottom and improving heat dissipation effect; the die mechanism and the pull-extruder of the invention have simple structure and low manufacture cost, are easy for production regeneration, have obvious technical contribution, and completely realize the aims of all the inventions.

Description

technical field [0001] The invention belongs to the field of pultrusion molding equipment for composite materials, and relates to a mold mechanism for composite thermoplastic molding of glass yarn and glass mat, in particular to a thermoplastic molding mold mechanism capable of online detection of pultrusion traction force and its pultrusion machine . Background technique [0002] In the known FRP pultrusion molding machine, the glass yarn and the glass felt are released freely from the creel and the felt frame respectively by the traction mechanism, so that the glass yarn and the glass felt are dipped in the glue solution through the glue tank, and then passed through the pultrusion tooling frame. The yarn plate and felt sleeve on the upper part enter the mold after pre-forming the mold. The mold is surrounded by the heating sleeve and heated. The glass yarn and glass felt soaked in the glue are solidified and formed through the inner cavity of the mold, and are drawn out b...
