Description

Technical Field

[0001] This utility model relates to the field of wood-plastic flooring production technology, specifically to an adjustable wood-plastic flooring extrusion mold. Background Technology

[0002] Wood-plastic composite flooring is a new type of environmentally friendly wood-plastic composite material product. It has many advantages such as waterproof and moisture-proof, wear-resistant and corrosion-resistant, easy to install and maintain, and beautiful appearance. It is commonly used in courtyards, terraces, garden landscapes, public buildings and other occasions, and its application is very wide.

[0003] Wood-plastic composite (WPC) flooring molds are crucial in WPC flooring production, as their design directly impacts product quality and production efficiency. Common WPC flooring molds typically include a mold head, transition plate, support plate, manifold plate, die, shaping mold, and mold core. The die, shaping mold, and mold core directly determine the structural shape and size of the WPC flooring product.

[0004] During the production process, it is common to encounter situations where wood-plastic composite flooring with the same structural shape but different sizes and models needs to be produced. In such cases, although the shapes of the corresponding die, mold, and core are compatible, the width of the die and mold and the number of corresponding cores cannot meet the requirements, so all of them need to be replaced. This results in a large number of molds required for the production of wood-plastic composite flooring, increasing production costs. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides an adjustable wood-plastic flooring extrusion mold, which solves the problem of requiring separate molds when producing wood-plastic flooring with the same structural shape but different sizes, resulting in a large number of molds and increased costs.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0007] An adjustable wood-plastic flooring extrusion die includes a die head fixedly installed at the front end of an extruder, and a transition plate, a support plate, a confluence plate, a die, a shaping die, and a plurality of die cores horizontally disposed inside the transition plate, the support plate, the confluence plate, the die, and the shaping die, respectively. The cavities inside the die head, the transition plate, the support plate, and the confluence plate are all connected, and the cavities are connected to the cavities inside the die and the shaping die.

[0008] A positioning rod is fixed longitudinally inside the mold cavity of the manifold. A positioning slot is provided on one side of the positioning rod corresponding to the support plate. Positioning insertion holes are provided at equal intervals longitudinally inside the positioning slot. The mold core is inserted into the positioning insertion hole and a positioning block is provided on its surface that is engaged in the positioning slot.

[0009] A limiting rod is fixed longitudinally inside the mold cavity of the mold head. A limiting groove is provided on one side of the limiting rod corresponding to the transition plate. A limiting protrusion is provided at one end of the mold core corresponding to the limiting rod, which is engaged in the limiting groove. The support plate and the transition plate are fixedly installed on the mold head by fixing bolts. The shaping mold, the orifice mold and the manifold are installed on the support plate by fastening bolts.

[0010] The mold cavity has longitudinally movable molding blocks that correspond to the two sides of the wood-plastic flooring on both the front and back sides of the mold cavity. The front and back sides of the mold are fixed with fixing seats at the positions corresponding to the molding blocks. The fixing seats are threaded with adjusting bolts that are rotatably connected to the molding blocks.

[0011] Preferably, the cavity inside the manifold is funnel-shaped, converging towards the die. The vertical dimensions of both ends of the cavity inside the manifold are the same as the vertical dimensions of the cavity of the support plate and the cavity of the die. The vertical dimension of the left end of the cavity inside the manifold and the vertical dimension of the cavity are both equal to the thickness of the wood-plastic flooring. The longitudinal width of the cavity inside the die is equal to the width of the wood-plastic flooring, and the longitudinal width of the left end of the cavity inside the manifold is not less than the longitudinal width of the cavity.

[0012] Preferably, the left end of the internal cavity of the manifold, as well as the top and bottom of the inner wall of the cavity of the orifice and the shaping mold, are provided with forming protrusions corresponding to the grooves on the upper and lower surfaces of the wood-plastic floor.

[0013] Preferably, the positioning slot is a rectangular strip, and the positioning block is square.

[0014] Preferably, the surface of the mold core is provided with a guide block integrally formed with the positioning block on the side of the positioning block away from the positioning rod.

[0015] Preferably, the vertical dimension of the shaping block is adapted to the vertical dimension of the mounting grooves on both sides of the wood-plastic flooring.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] This invention, by setting up a detachable manifold, die, shaping die, and die core, allows for the adjustment of the number of detachable die cores according to the different widths of wood-plastic composite flooring with the same structural shape but different sizes. The spacing between the shaping blocks within the shaping die is adjusted to accommodate the mounting slots on wood-plastic composite flooring of different widths. By simply changing the die, wood-plastic composite flooring with the same structural shape but different sizes can be produced, improving the functionality of the die and significantly reducing the total number of dies required for wood-plastic composite flooring production. This reduces production costs from the source and solves the problem of requiring separate dies for wood-plastic composite flooring with the same structural shape but different sizes, which leads to a large number of dies and increased costs.

[0031] A positioning rod 10 is fixed in the mold cavity 8 of the manifold 4 along the longitudinal direction. A positioning slot 11 is provided on one side of the support plate 3 corresponding to the positioning rod 10. The positioning slot 11 is a rectangular slot, and positioning insertion holes 12 are provided at equal intervals along the longitudinal direction in the positioning slot 11. The mold core 7 is inserted into the positioning insertion hole 12 and a positioning block 13 is provided on its surface that is engaged in the positioning slot 11.

[0032] The positioning hole 12 can be round or rectangular, and is used to install the mold core 7 with a cylindrical or quadrangular prism structure. It can produce wood-plastic flooring 19 with a round or rectangular hole. The surface of the mold core 7 is provided with a guide block 25 integrated with the positioning block 13 on the side of the positioning block 13 away from the positioning rod 10. The positioning block 13 is square.

[0033] A limiting rod 14 is fixed longitudinally inside the mold cavity 8 of the mold head 1. A limiting groove 15 is provided on one side of the limiting rod 14 corresponding to the transition plate 2. A limiting protrusion 16 is provided on one end of the mold core 7 corresponding to the limiting rod 14, which is engaged in the limiting groove 15. The support plate 3 and the transition plate 2 are fixedly installed on the mold head 1 by fixing bolts 17. The shaping mold 6, the orifice mold 5 and the manifold 4 are installed on the support plate 3 by fastening bolts 18.

[0034] The mold cavity 8 of the molding mold 6 has molding blocks 20 that are longitudinally inserted into the front and back sides of the inner wall, corresponding to the two sides of the wood-plastic flooring 19. The vertical dimension of the molding block 20 is adapted to the vertical dimension of the mounting slots 26 on both sides of the wood-plastic flooring 19. The front and back sides of the molding mold 6 are fixed with fixing seats 21 at the positions corresponding to the molding blocks 20. The fixing seats 21 are threaded with adjusting bolts 22 that are rotatably connected to the molding blocks 20.

[0035] The cavity 8 inside the manifold 4 is a bucket shape that converges towards the mold 5.

[0038] The manifold 4, die 5, shaping die 6, and die core 7 can be individually disassembled and assembled using fastening bolts 18 without changing the die head 1, transition plate 2, and support plate 3. Depending on the width of the wood-plastic composite flooring 19 of the same structural shape but different sizes required to be produced, the number of detachable die cores 7 can be changed accordingly. The spacing between the shaping blocks 20 in the shaping die 6 can be changed by turning the adjusting bolts 22 to adapt to the mounting slots 26 on the wood-plastic composite flooring 19. By replacing the die 5 that determines the shape of the wood-plastic composite flooring 19, wood-plastic composite flooring 19 of the same structural shape but different sizes can be produced, which is convenient, practical, and economical.
