Problems solved by technology
[0004] Although the pultrusion technology of FRP has been widely used, the existing pultrusion dies and processes are mainly aimed at FRP products with relatively simple profiles. For regular hexagonal anode tubes with closed hollow profiles Products that are difficult to use with existing pultrusion dies can be produced by pultrusion
[0005] In addition, the existing pultrusion molding technology adopts the outsourcing heating method, that is, during the heating process, the heating device is close to the outer mold of the pultrusion mold to heat, and the heat is transferred to the inner cavity through the outer mold of the pultrusion mold , for example, the heating plate is attached to the steel mold used as the outer mold, and the heat is transferred through the steel mold. In this way, most of the heat will be dissipated into the air, the heat loss is large, and the heating time is long, and for the regular hexagonal anode tube such It is difficult to ensure the uniformity of heating during molding and curing

Abstract
The invention relates to a pultrusion mould, which comprises a pre-formed support frame, an inner mould and an outer mould, wherein the inner mould is fixedly connected with the pre-formed support frame; the outer mould surrounds the outside of the inner mould; a cavity, the size of which is the same to that of the section of a conductive orthohexagonal glass reinforced plastic anode tube, is formed by the inner mould and the outer mould; the inner mould is provided with an extension support shaft; both the two head surfaces of the outer mould are provided with a plurality of deep holes for holding heating tubes on each edge of each regular hexagon; the middle part of the outer mould is provided with grooves for holding the heating tubes on each edge of each regular hexagon; the pre-formed support frame is in a hollow frame structure; a support frame for fixing the support shaft is arranged at the head part of the pre-formed support frame; a plurality of pre-formed plates are connected to the pre-formed support frame in sequence; and slots are formed in the pre-formed plates. The pultrusion mould provided by the invention is capable of producing the electro-conductive orthohexagonal glass reinforced plastic anode tube by adopting a pultrusion process. The invention further provides the conductive orthohexagonal glass reinforced plastic anode tube produced by using the pultrusion mould.
Description
technical field [0001] The invention relates to a pultrusion die, in particular to a pultrusion die used for the production of glass fiber reinforced plastic products. The invention also provides a regular hexagonal anode tube of conductive glass fiber reinforced plastic produced by using the above pultrusion die. Background technique [0002] In the wet electrostatic precipitator used to remove fine dust, gypsum droplets, etc., the anode tube made of conductive glass fiber reinforced plastics has been used more and more. The regular hexagonal anode tube is easy to assemble and has a large dust collection area. , so the commercially available anode tubes all adopt the regular hexagonal structure, but the current commercially available conductive FRP regular hexagonal anode tubes all adopt the production method of manual layering, the production efficiency is low, and, because it is handmade, the anode tube It is difficult to obtain a stable surface quality on the inner surfa...
