Problems solved by technology

Thereby, the plastic plate that is made with plastic as raw material is then more and more adopted by people, and when the plastic plate of prior art is selected as the plate of above-mentioned product for use, a kind of is to adopt injection molding mode to make, but, The quality of the plastic board of this structure is relatively heavy, it is very inconvenient to move, and it requires expensive equipment and molds, especially for large-sized boards, it is not easy to make; the other is made by blister forming. Although the board has the characteristics of light weight, easy cleaning, low cost and beautiful appearance, the strength of this composite board is not enough, which brings certain limitations to the use and affects the competitiveness of the product

Embodiment 1

[0053] Embodiment one, see figure 1 As shown in Figure 7, an ultrasonically welded plastic-absorbing injection-molding composite board of the present invention is used on a seat, figure 1 A schematic diagram of the structure of a seat is given. The seat includes a chair frame 3, a chair panel 1 and a chair back 2 mounted on the chair frame 3. Both the chair panel 1 and the chair back 2 are plastic injection molded by ultrasonic welding. Blister composite board.

[0054] Such as Figure 2 to Figure 5 As shown, the chair board 1 includes:

[0055] The plastic panel 11 is a monomer structure with a certain shape made by direct extrusion molding or extrusion molding, and has an upper surface and an inner surface;

[0056] The plastic bottom plate 13 is a monomer structure with a certain shape made by direct extrusion molding or extrusion molding, and has an inner surface and a lower surface;

[0057] The injection molded part 12 is a single structural part made by direct injec...

Embodiment 2

[0065] Embodiment two, see Figure 8 As shown, an ultrasonically welded plastic-absorbing plastic-absorbing composite board of the present invention is used on a seat. The difference from Embodiment 1 is that the surface of the panel is provided with a printing layer 112, which is made The printing method directly prints the texture or pattern structure on the surface of the panel. For example, the upper surface of the panel 11 can be printed to produce various colors of natural materials such as wood grain and marble. The upper surface of the plastic panel can also be provided with textures or pattern structures produced by the transfer film. For example, the surface of the panel can be compounded with a transfer film with various wood grains, marble and other natural material colors. Remove the film and spray heat-cured or light-cured varnish to increase the hardness and weather resistance of the surface.

Embodiment 3

[0066] Embodiment three, see Figure 9 to Figure 1 As shown in 0, a kind of ultrasonically welded plastic-absorbing injection-molding composite board of the present invention is used on a seat, Figure 9 A schematic diagram of the structure of another structural seat is given. The seat includes a chair frame 30, a seat board 10 mounted on the chair frame 30, and a chair back 20. Both the chair board 10 and the chair back 20 are ultrasonically welded. Plastic injection molding composite board.

[0067] Among them, the chair board 10 includes a plastic panel 15, a plastic bottom plate 18, an injection molded part 16 and an embedded reinforcement 17; The single structure of the single body; the injection molded part 16 is two monomers, which are respectively located on both sides of the chair board, and the upper and lower parts of the injection molded part 16 are integrally injection molded with ribs or bumps (not shown), and the plastic panel 15 1. When the plastic bottom pla...

Abstract

The invention discloses a plastic injection moulding composite board of ultrasonic welding, including a plastic panel, a plastic pallet, a injection moulding piece, the plastic panel and the plastic pallet are directly extruded to shape or shape by suction after extruding; the injection moulding piece can shape by direct injection moulding or by plural injection moulding pieces; the contact area of the injection moulding piece and the plastic panel, the plastic pallet are welded together by ultrasonic, wherein the contact area of the inner surface of the injection moulding piece and the plastic panel, the plastic pallet is provided with protruding ribs or salient points melted between the panel, the pallet and the injection moulding piece to make them connected together when the ultrasonic is welding, also an inner buried reinforcement is added between the plastic panel and the plastic pallet under the condition with higher requirement, which advance the strength and reduce the dose of plastic pieces. After adopting the structure, the plastic composite board has the advantages of low cost, few materials, easy manufacture, light quality, easy automatization, even surface, cleaness etc., which can be used in the chair board, the file cabinet, the article storing cabinet, the material frame, the wall decorative board, the wardrode clapboard etc.

Description

technical field [0001] The invention relates to a plastic composite board, in particular to a plastic-absorbing injection-molding composite board welded by ultrasonic waves. Background technique [0002] Panel is a material commonly used in the construction industry or furniture manufacturing industry. For example, it can be used as a wall decoration panel, or it can be used to make the panel of the table, the seat and back of the chair, the partition of the bookshelf or the cabinet, the head of the bed or the The bezel at the end of the bed, etc. The earlier wall decoration panels, or the panels of various tables such as conference tables, dining tables, leisure tables, computer tables, etc., or the seat and backrest of chairs, bookshelves or cabinet partitions and other indoor and outdoor products. Most of the boards in my country still use wood boards, fiberboards or particle boards. These wood-based boards will be used less and less with the reduction of forest resources...
