Description

Technical Field

[0001] The utility model relates to the field of wood plastic flooring, in particular to a mold for producing wood plastic flooring. Background Art

[0002] Wood-plastic flooring is a new type of environmentally friendly wood-plastic composite material. Wood phenol, produced during the production of medium- and high-density fiberboard, is added to recycled plastic and pelletized to form a wood-plastic composite material. This composite material is then extruded into a wood-plastic flooring production unit. The wood-plastic flooring is waterproof and moisture-resistant, fundamentally resolving the problem of wood products being susceptible to rotting, swelling, and deformation after absorbing moisture in humid and water-rich environments. It can be used in environments where traditional wood products cannot be used. Existing molds for embossing and texturing boards used in the production of wood-plastic flooring have the following drawbacks: they are inconvenient for fixing and clamping boards of varying widths, and are not convenient for embossing and forming the boards. Therefore, application number CN202221844109.X discloses a mold for embossing and texturing boards used in the production of wood-plastic flooring. The mold comprises a processing table, a fixing mechanism, and bolts. Bolts for mounting the fixing mechanism are detachably connected to the upper surface of the processing table. The fixing mechanism comprises screws, a plate frame, and rubber blocks. The plate frame is detachably connected to the upper surface of the processing table. The upper surface of the plate frame is mounted with evenly arranged screws for fixing the boards, and the lower surface of the screws is fixedly connected to the rubber blocks. The screws, plate racks and rubber blocks provided on the surface of the processing table facilitate the fixing of plates of different widths and sizes, thus facilitating the embossing operation of the plates.

[0003] However, the above scheme still has certain defects. The inventors have found through research that in the above scheme, the mold plate is installed on the threaded column set at one end of the piston rod of the hydraulic device through a threaded connection, but there is a lack of a limiting mechanism for the mold plate. As the mold plate is repeatedly subjected to force and moves up and down, the mold plate may rotate independently, causing the embossing angle of the mold plate to shift, increasing the product defective rate and even causing the mold plate to fall off, affecting the normal embossing work. At the same time, connecting the mold plate only through the threaded column will result in a smaller force area and a more concentrated force point, which may cause the mold plate to be unevenly stressed when embossing the floor, affecting the embossing effect.

[0004] How to invent a wood plastic floor production mold to improve these problems has become a problem that needs to be solved urgently by those skilled in the art. Utility Model Content

As the mold plate is repeatedly subjected to force and moves up and down, the mold plate may rotate independently, resulting in the embossing angle of the mold plate being offset, increasing the product defective rate and even causing the mold plate to fall off, affecting the normal embossing work. At the same time, connecting the mold plate only through a threaded column will result in a smaller force area and a more concentrated force point, which may cause the mold plate to be unevenly stressed when embossing the floor, affecting the embossing effect.

DETAILED DESCRIPTION

[0020] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] See also Figures 1 to 4 The utility model provides a technical solution: a mold for producing wood plastic flooring, comprising a placing table 1, with slide grooves 101 on both sides of the upper surface of the placing table 1, and a plurality of floor limiting mechanisms 3 slidably installed in each slide groove 101. A mounting frame 102 is fixedly installed between the two side surfaces of the slide groove 101, and a hydraulic cylinder 4 is fixedly installed on the surface of one side of the mounting frame 102. One end of the piston rod of the hydraulic cylinder 4 is fixedly connected to the embossing mold mechanism 2. The embossing mold mechanism 2 includes a mounting plate 201, and the mounting plate 201 is fixedly connected to one end of the piston rod of the hydraulic cylinder 4. The bottom of the mounting plate 201 is fixedly connected to a plurality of parallel slide rails 202 through a connecting piece. A mold plate 205 is arranged parallel to the lower side of the mounting plate 201, and a plurality of connecting slide grooves 206 corresponding to the slide rails 202 are opened on the surface of the mold plate 205 facing the side of the mounting plate 201. Each connecting slide groove 206 is slidably connected to the corresponding slide rail 202, and a blocking mechanism is provided on the surface of one end of the mold plate 205 at the opening of each connecting slide groove 206.

[0022] See also Figure 2 and Figure 3 , the number of the slide rails 202 and the connecting slide grooves 206 is at least two.

[0023] The more the slide rails 202 and the connecting slide grooves 206 are provided, the larger and more uniform the overall force-bearing area of ​​the mold plate 205 will be, thereby reducing the situation where the embossing effect is affected by uneven force.

[0024] Furthermore, each connecting member includes a telescopic rod 203, one end of the telescopic rod 203 is fixedly connected to the bottom surface of the mounting plate 201, and the other end of each telescopic rod 203 is fixedly connected to the upper surface of the corresponding slide rail 202. Each telescopic rod 203 is provided with a spring 204 on the outside, and the two ends of each spring 204 are respectively fixedly connected to the bottom surface of the mounting plate 201 and the top surface of the corresponding slide rail 202.

[0025] The mounting plate 201 and the slide rail 202 are connected by the telescopic rod 203 to achieve two-stage pressure on the mounting plate 201. When the mold plate 205 just contacts the wood plastic floor, the telescopic rod 203 is in an extended state, and the staff can check whether the embossing position is appropriate. After the check is completed, the telescopic rod 203 is compressed by the hydraulic cylinder 4. After the telescopic rod 203 is contracted to the limit state, the slide rail 202 can be used to apply uniform pressure to the entire mold plate 205 to complete the embossing work, thereby improving the accuracy of the embossing work and reducing the defective rate in product production.

[0026] Furthermore, each blocking mechanism includes a limit plate 207, and through grooves are opened at both ends of the surface of one side of the limit plate 207. A fixing bolt 208 is inserted in each through groove, and one end of each fixing bolt 208 is threadedly connected to the corresponding screw hole 209. The two screw holes 209 are opened on the surface of one end of the mold plate 205 and are located on both sides of the opening of the corresponding connecting slide groove 206.

[0027] The length of the slide rail 202 is consistent with the length of the connecting slide groove 206. When the mold plate 205 is slidably connected to the slide rail 202 as a whole through the connecting slide groove 206, each limit plate 207 is placed at the opening of the corresponding connecting slide groove 206, and the through groove set on the surface of the limit plate 207 is made to correspond to the position of the screw hole 209. The fixing bolt 208 is passed through the through groove and threadedly installed in the screw hole 209. The limit plate 207 is fixed on the surface of one end of the mold plate 205 to limit the corresponding slide rail 202, thereby ensuring stability during use. The mold plate 205 and the mounting plate 201 are connected by the cooperation of the slide rail 202 and the connecting slide groove 206. While expanding the force area to ensure the uniformity of embossing, it can also prevent the mold plate 205 from independent displacement and rotation.

[0028] See also Figure 4 Each floor limiting mechanism 3 includes a first slider 301, which is slidably installed in the corresponding side slide 101. One end of the rotating shaft 302 is rotatably installed on the upper surface of the first slider 301, and the other end of the rotating shaft 302 is fixedly connected to the rotating plate 303. An adjusting slide 304 is provided on the upper surface of the rotating plate 303, and a second slider 305 is slidably installed in the adjusting slide 304. A threaded hole is provided on the top surface of the second slider 305, and a threaded rod 306 is threadedly connected to the threaded hole. The bottom end of the threaded rod 306 is connected to a pressure block 307.

[0029] The first slider 301 is slidably installed in the slide groove 101, so each floor limiting mechanism 3 can independently adjust its position relative to the entire placement platform 1, thereby reducing limitations during use and improving adaptability to wood-plastic floors of different sizes. At the same time, the rotating plate 303 as a whole can also be independently rotated at an angle through the rotating shaft 302, and the second slider 305 can adjust the position of the pressing block 307 in the adjusting slide groove 304, so that the contact position of the pressing block 307 with the floor can be adjusted in multiple directions and angles to avoid affecting the normal progress of the embossing work. Rotating the threaded rod 306 can make it move up and down in the threaded hole, so that the pressing block 307 can contact or separate from the floor surface.

[0030] Furthermore, the pressing block 307 is rotatably connected to the bottom end of the threaded rod 306 .

[0031] After the pressure block 307 is attached to the floor surface, the pressure block 307 can still be rotated 306 to apply pressure to the floor, thereby ensuring the stability of the limit.

[0032] Furthermore, the pressing block 307 is made of rubber.

[0033] The rubber material can not only increase the friction between the pressing block 307 and the floor to ensure the limiting stability, but also protect the floor surface and reduce the product loss rate during the embossing process.

[0034] Working principle: Place the wood plastic floor on the placement table 1, adjust the position of each floor limit mechanism 3 according to the embossing area, and adjust the contact position of the pressing block 307 on the floor by rotating the angle of the rotating shaft 302 and sliding the second slider 305 to prevent the limit from affecting the embossing work. After completing the limit work on the floor, start the hydraulic cylinder 4 to drive the mounting plate 201 to descend, and the mold plate 205 will also descend at the same time. When the mold plate 205 just contacts the floor, the staff can check whether the embossing position is correct, and then continue to drive the mounting plate 201 to descend through the hydraulic cylinder 4 to compress the telescopic rod 203 to the mold plate 205 applies pressure as a whole to complete the embossing work. When a different mold plate 205 needs to be replaced, it is only necessary to remove all the fixing bolts 208 and the limit plate 207, slide the mold plate 205 out of the connection state with the slide rail 202, replace the new mold plate 205, and then fix it with the fixing bolts 208 and the limit plate 207. The mounting plate 201 and the mold plate 205 are connected by the cooperation of the slide rail 202 and the connecting groove 206. The force-bearing area can be increased to ensure the uniformity of embossing, while also avoiding the independent displacement and rotation of the mold plate 205 to reduce the accuracy of the embossing work.

[0035] It should be noted that the specific model and specifications of the hydraulic cylinder 4 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] The power supply and principle of the hydraulic cylinder 4 are clear to those skilled in the art and will not be described in detail here.

[0037] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
