Abstract

The invention discloses a glue injection mold and a glue injection unit for a pultrusion glue injection device of a glass reinforced plastic tube, is a divisional application of the original application of 200910069146.0 Glue Injection Unit and Glue Injection Mold for Pultrusion Glue Injection Device of Glass Reinforced Plastic Tube, and relates to a glue solution impregnation device in pultrusion equipment for compounding and hot-setting glass yarns and felts into a continuous section. The glue injection unit comprises the glue injection mold and a mandrel that can guide a glass reinforced plastic molding material to hollowly enter a pultrusion mold, wherein a mandrel through hole allowing the mandrel to pass through is formed in the glue injection mold; injection cavities are arranged along the mandrel through hole; and a negative pressure cavity is arranged between each two adjacent injection cavities. The glue injection mold adopted by the glue injection unit reasonably configures structures of the injection cavities and the negative pressure cavity, so that the glass yarn and felt impregnation work can be accomplished by injecting a glue solution in a closed mold device, the problem that the glue solution is volatilized freely is solved effectively, and the stability of the glue solution viscosity in the whole pultrusion process is ensured effectively. The integral forming mold and mold blocks more facilitate industry popularization.

Description

[0001] technical field [0002] The invention belongs to the field of pultrusion molding equipment for composite materials, and relates to a device for compounding and thermosetting glass yarn and felt into a continuous profile, in particular to a glue injection unit and a mold of a glue injection device for pultruding glass steel pipes. This case is a divisional application of the original application "200910069146.0 Glue injection unit and glue injection mold for glass steel pipe pultrusion glue injection device". Background technique [0003] In the known FRP pultrusion molding machine, the glass yarn and the felt are released freely from the creel and the felt frame respectively by the traction mechanism, so that the glass yarn and the felt are dipped in the glue solution through the glue tank, and then passed through the pultrusion tooling frame. The gauze board and the felt sleeve enter the mold after the preforming mold, and the mold is surrounded by the heating sleev...
