Description

Technical Field

[0001] The utility model relates to the technical field of hollow grid plate production, in particular to a high-efficiency and high-stability hollow grid plate extrusion die. Background Art

[0002] Hollow lattice board is a new type of material that is light in weight (hollow structure), non-toxic, pollution-free, waterproof, shock-proof, anti-aging, corrosion-resistant, and colorful. When producing hollow lattice board, it needs to be produced through an efficient and stable extrusion die.

Although the above-mentioned document can realize more sufficient and uniform material supply, compressed air is passed through the interior of the product, and the surface flatness and quality of the product can be controlled by adjusting the air flow; however, when in use, the efficient and highly stable extrusion die extrude the molten hollow grid plate raw material through the extrusion nozzle of the extrusion die during the process of extruding the hollow grid plate. Due to the fact that the extrusion nozzle is used for a long time, The extrusion nozzle is prone to clogging, and the extrusion nozzle needs to be disassembled from the extrusion mold for cleaning. Since it is troublesome to disassemble the extrusion nozzle and the disassembly speed is slow, the use effect of the high-efficiency and high-stable extrusion mold is reduced; at the same time, when the high-efficiency and high-stable extrusion mold extrude the empty lattice plate, the melted empty lattice plate raw material has a certain stability. When the raw material enters the extrusion mold, the heat of the raw material is transferred to the extrusion mold in the form of heat transfer, resulting in a relatively high stability of the extrusion mold surface. If the staff accidentally touches the extrusion mold, the staff will be scalded, thereby reducing the safety of the high-efficiency and high-stable extrusion mold. Utility Model Content
