Anti-cracking wood-plastic extrusion die

Abstract

The invention discloses an anti-cracking wood-plastic extrusion die that comprises a fixed frame 1; a driving rod 2 is rotationally connected into the fixed frame 1; supporting blocks 3 are fixedly connected to the two sides of the inner wall of the fixed frame 1; the front surface of the supporting block 3 is rotationally connected with a linkage block 4; the surface of the driving rod 2 is in threaded connection with a driving block 5; the front surface of the driving block 5 is rotationally connected with a linkage rod 6; one end of the linkage rod 6 is rotationally connected with the surface of the linkage block 4, a shaft rod 7 is fixedly connected to the surface of the linkage block 4, fixing grooves 8 are formed in the top and the bottom of the inner wall of the fixed frame 1 correspondingly, and the inner walls of the fixing grooves 8 are slidably connected with the surface of the driving block 5. According to the anti-cracking wood-plastic extrusion die, the problem that the size of a gap of an existing rotating nut cannot be freely adjusted is solved, the application range of the rotating nut is widened, the use of a user is greatly guaranteed, and the working efficiencyis improved.

Description

technical field [0001] The invention relates to the technical field of wood-plastic molds, in particular to an anti-cracking wood-plastic extrusion mold. Background technique [0002] The plastic is made of recyclable plastic and wood corners after a certain process. It combines the advantages of both plastic and wood. The outer surface of the second-generation functional co-extruded wood-plastic wraps multi-layer nano-molecules, and the performance of anti-corrosion and water absorption is improved. Pushed to world-class standards, and the appearance is comparable to solid wood, with the characteristics of wood and plastic; compared with wood, wood-plastic is non-corrosive, not afraid of water, mildew-proof, long life, and can also be made into fireproof. [0003] When WPC is molded by extrusion mould, different materials and additives will impact in the mold to cause different pressures, making the internal structure of WPC after cooling uneven, making WPC easy to crack an...
