Description

Technical Field

[0001] This utility model relates to the field of decorative mirror frame technology, and in particular to a decorative mirror frame. Background Technology

[0002] Decorative frames (such as picture frames, painting frames, and mirror frames) are common home and commercial decorative items. Currently, the manufacturing of these frames primarily employs the following methods: 1. Solid wood mirror frames: These are typically made from woods such as pine and oak, and are produced through processes such as sawing, planing, tenoning, splicing, and carving. Their advantages include a natural and high-end feel, but they also have significant disadvantages: High material costs and low utilization rate: It relies on high-quality wood, and the processing generates a lot of shavings and scraps, resulting in serious waste.

[0003] Complex and inefficient processes: Especially for frames with complex shapes or carvings, they rely heavily on manual or complex mechanical processing, resulting in low production efficiency and difficulty in scaling up production.

[0004] Structural stability issues: Wood is susceptible to cracking and deformation due to temperature and humidity fluctuations, especially at joints, which can easily loosen and affect the quality and lifespan of the finished product.

[0005] 2. Plastic frames: Plastics (such as PS and ABS) are injection molded or cut to shape. Their advantages are low cost and ease of mass production, but their disadvantages are equally obvious: Not environmentally friendly: MDF uses formaldehyde-containing adhesives, and the plastics are petroleum-based products, which does not conform to the trend of green consumption.

[0006] Cheap texture: The product lacks the texture and warmth of natural wood, has a cheap appearance, and is difficult to meet the needs of the mid-to-high-end market.

[0007] Poor durability: Plastic is prone to aging and discoloration.

[0008] In addition, regardless of whether it is solid wood or engineered wood, the production of picture frames with complex three-dimensional patterns (such as European carvings and Chinese textures) requires subsequent carving processes, which further increases costs and time.

[0009] Therefore, existing technologies are insufficient in terms of high environmental friendliness, low cost, high material utilization, and one-time molding of complex shapes. The market urgently needs a new frame manufacturing solution that can take into account natural aesthetics, environmental protection, and efficient production. Utility Model Content

[0010] The purpose of this utility model is to provide a decorative mirror frame that solves the problem that conventional decorative mirror frames cannot be molded in one piece to achieve structural stability, rich shapes, and a natural wood-like texture.

[0011] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: This utility model provides a decorative mirror frame, including an upper mirror frame, a first side wall frame, a second side wall frame, and a lower frame body that are connected end to end to form a closed mirror frame. The back of the closed frame is provided with a slot for mounting a mirror or back panel, and the front is provided with a decorative layer around it. The upper frame, the first side wall frame, the second side wall frame, and the lower frame are integrally formed structures. The upper frame, the first side wall frame, the second side wall frame, and the lower frame each include a support strip and a molded layer disposed outside the support strip.

[0012] Furthermore, in this embodiment, mounting holes for hanging brackets are symmetrically provided on the back of the closed mirror frame.

[0013] Furthermore, in this embodiment, the upper frame is a semi-circular arc shape.

[0014] Furthermore in this embodiment, the decorative layer is a patterned structure integrally formed on the closed mirror frame.

[0015] Furthermore in this embodiment, the decorative layer consists of stepped raised strips.

[0016] This utility model provides a decorative mirror, which includes a decorative mirror frame as described above and a mirror fitted in the slot.

[0017] This utility model provides a molding die for a decorative mirror frame, which includes a cavity adapted to the structure of the aforementioned decorative mirror frame.

[0018] Compared with the prior art, the beneficial technical effects of this utility model are as follows: This invention uses wood fiber and environmentally friendly adhesive as the main materials for hot pressing of decorative mirror frames, thus turning waste wood into treasure, reducing deforestation and solid waste. The product is biodegradable or recyclable. By controlling the density, a lighter product than solid wood mirror frames can be produced, which is convenient for hanging and transportation.

[0019] In addition, the molding process for decorative mirror frames is simplified, resulting in high production efficiency. The traditional multi-step process (sawing, planing, carving, and assembling) is integrated into "one-time molding," which is particularly suitable for the large-scale production of complex-shaped products and significantly shortens the production cycle.

[0020] Furthermore, the structure involved is strong and not easily deformed: the molded product has interwoven internal fibers, an isotropic structure, and low internal stress. Additionally, four thin bamboo strips are added during the filling process to act as reinforcing steel. Frames processed using this technique are less prone to cracking and deformation compared to spliced ​​solid wood frames.

[0021] It can also accurately replicate any complex three-dimensional decorative patterns, and each product has a unique natural texture due to the random distribution of wood fibers, combining artistry and industrial consistency. Attached Figure Description

[0025] This embodiment discloses a decorative mirror frame, including an upper mirror frame 11, a first side wall frame 12, a second side wall frame 13, and a lower frame 14 that are connected end to end to form a closed mirror frame 1. A slot 2 for mounting a mirror or back panel is integrally formed on the back of the closed mirror frame 1, and a decorative layer 4 is integrally formed around its front. The upper mirror frame 11, the first side wall frame 12, the second side wall frame 13, and the lower frame 14 are integrally formed structures. Each of the upper mirror frame 11, the first side wall frame 12, the second side wall frame 13, and the lower frame 14 includes a support strip and a molded layer installed outside the support strip. The support strip is a bamboo strip, and the molded layer is a cured mixture of wood fiber and environmentally friendly adhesive.

[0026] refer to Figure 1 The back frame of the enclosed mirror frame 1 is also symmetrically designed with mounting holes 3 for hanging.

[0027] In this embodiment, the upper frame 11 is semi-circular, the first side wall frame 12 and the second side wall frame 13 are elongated structures, and the second side wall frame 13 is a horizontal structure.

[0028] In this embodiment, the decorative layer 4 is a patterned structure integrally formed on the closed mirror frame 1.

[0029] refer to Figure 5 and Figure 6 The decorative layer 4 consists of stepped protrusions. Specifically, the bottom step is 15mm high, the second and third steps are 8mm high, and the step widths from top to bottom are 17mm, 17mm, and 32mm, respectively.

[0030] In specific implementation, a decorative mirror is designed according to the above content, which includes a decorative mirror frame as described above and a mirror assembled in the slot 2.

[0031] In order to integrally process the upper frame 11, the first side wall frame 12, the second side wall frame 13, the lower frame 14, the slot 2 and the decorative layer 4 thereon, a molding die for the decorative frame can also be designed, the molding die including a cavity corresponding to the above features.

[0032] In this embodiment, the frame is made of a mixture of wood fiber and environmentally friendly adhesive. The wood fiber is derived from wood processing residues, and the environmentally friendly adhesive includes thermosetting resin and filler material. The weight ratio of the two components can be 6-7% EO urea-formaldehyde resin, 90-92% plant fiber, and 2-3% MDI.

[0033] The specific steps of the production process are as follows: Raw material pretreatment and crushing: The collected waste wood is cleaned and dried to remove impurities such as metal and plastic. Then, it is crushed into wood fibers or wood powder with uniform particle size using a crusher.

[0034] Mixing and stirring: Add the crushed wood fiber and environmentally friendly adhesives (such as water-based polyurethane resin, soybean protein glue, etc.) in a predetermined ratio.

[0035] Dyes can be added according to design requirements and stirred thoroughly to form a smooth and uniform mixture.

[0036] Loading and Pre-pressing: The mixture is quantitatively filled into the cavity of a preheated molding die. The die is the negative shape of the existing frame, and its cavity already includes all the complex patterns and designs on the front of the frame (such as carvings and textures) as well as the slot structure on the back. Pre-pressing can be performed first to ensure uniform distribution of the mixture.
