Description

Technical Field

[0001] The utility model relates to a range hood accessory, in particular to a range hood packaging foam and a molding die thereof. Background Art

[0002] In the production and design of modern kitchen appliances, range hoods are an indispensable component in the kitchen environment, and their functionality and appearance design are highly valued by consumers and manufacturers. Range hoods not only need to effectively remove the fumes generated during cooking to maintain indoor air quality, but also need to be designed to coordinate with the overall style of the kitchen to meet consumers' requirements for home aesthetics.

[0003] As the market demand for personalized and diversified designs grows, range hood manufacturers are faced with the challenge of providing diversified appearance designs to meet the needs of different consumers while maintaining product functionality. To address this problem, manufacturers usually maintain a unified standard for the main components of the range hood and achieve product appearance diversification by changing the design of the external panels. This approach effectively utilizes existing production lines and processes, reducing the cost and complexity of large-scale structural adjustments to meet different design requirements.

[0004] However, this strategy of driving design diversity with panel changes brings a significant follow-up problem: packaging materials, especially packaging foam used to protect the product during storage and transportation, need to closely match the shape and size of the range hood. Since the shape and size of the panel vary with the design, standardized or universal packaging foam often cannot meet the needs of all products. This results in the need to develop new packaging foam every time the panel design changes, and then the need to design and manufacture new molds. The development of molds is not only costly, but also prolongs the product's cycle from design to market, increases production costs, and ultimately increases the purchase cost for consumers.

[0005] In addition, for packaging material manufacturers, frequent mold replacement not only means higher material and maintenance costs, but also involves reduced production efficiency. Each mold replacement requires downtime and debugging, which not only affects production efficiency, but may also affect the quality stability of packaging materials. In today's increasingly competitive market, these problems may become a major obstacle to the development of enterprises, so it is necessary to make further improvements. Utility Model Content

[0025] Preferably, support columns 7 are provided on both sides of the packaging area 3 of the front foam 1 protruding outward, and correspondingly, support grooves 8 are provided on both sides of the packaging area 3 of the rear foam 2. After the front foam 1 is connected with the rear foam 2, the support columns 7 are pressed into the support grooves 8.

[0026] Preferably, a panel limiting column 9 is provided on the inner side surface of the support column 7 of the front foam 1 , and after the front foam 1 is docked with the rear foam 2 , the panel limiting column 9 presses against the panel 42 of the range hood product 4 .

[0027] A molding die for range hood packaging foam comprises a front die 10 and a rear die 11. A cavity 12 is concavely arranged on the opposite surfaces of the front die 10 and the rear die 11. After the front die 10 and the rear die 11 are closed, a foaming material is injected into the cavity 12 to form a packaging foam product. A core die 13 is detachably installed in the cavity 12 of the front die 10. The molding surface of the core die 13 is set to a corresponding shape according to the range hood panel to be packaged.

[0028] Preferably, a concave docking area 14 is provided in the cavity of the front mold 10 , and the core mold 13 is connected to the docking area 14 via a docking seat 15 on the back side thereof.

[0029] Preferably, a screw hole is provided on the connection surface of the docking seat 15 , and a fixing bolt passes through the docking area 14 and is connected to the screw hole to fix the core mold 13 in the docking area 14 .

[0030] Working principle: The range hood packaging foam design of the present invention mainly realizes its functions through several key structures: front foam 1, rear foam 2, positioning column 5, clamping area 6, support column 7, support groove 8 and panel limit column 9.

[0031] Among them, the front foam 1 and the rear foam 2: these two parts constitute the main body of the packaging foam, which are respectively fixed to the front and rear surfaces of the range hood product 4. The packaging area 3 is designed on the opposite surfaces of the front foam 1 and the rear foam 2 to accommodate the range hood product 4 to ensure its stability and safety during transportation and storage.

[0032] Positioning columns 5: Two outwardly protruding positioning columns 5 are arranged in the packaging area 3 of the front foam 1 and the rear foam 2. When the front foam 1 and the rear foam 2 are connected, the two relative positioning columns 5 press against each other, which plays a role in transmitting pressure to each other, so that the pressure from the foam can be directly transmitted, avoiding deformation of the range hood product due to force, and improving the supporting force of the foam.

[0033] Clamping area 6: The clamping area 6 formed between the two positioning columns 5 is used to clamp the air cabinet part of the range hood product 4, thereby providing fixation and protection for the air cabinet.

[0034] 4. Support columns 7 and support grooves 8: Support columns 7 are provided on both sides of the packaging area 3 of the front foam 1, and support grooves 8 are provided on both sides of the packaging area 3 of the rear foam 2. This docking design provides additional stability when the front foam 1 and the rear foam 2 are combined, ensuring that the packaging foam is not easily deformed when subjected to external forces, and avoiding direct transmission of pressure to the range hood product.

[0035] 5. Panel limiting column 9: In order to further ensure the stability of the range hood product 4 during transportation and storage, the inner side of the support column 7 of the front foam 1 is provided with a panel limiting column 9, which is used to directly press on the panel 42 of the range hood product 4. Usually, it presses on both sides of the panel so that the main body of the panel does not contact the foam and forms a suspension, thereby preventing the panel made of glass material from being deformed or even broken due to stress.

[0036] Working principle of molding die:

[0037] 1. The front mold 10 and the rear mold 11: The molding mold is composed of a front mold 10 and a rear mold 11, and a cavity 12 is concavely arranged on the opposite surfaces thereof to form the specific structure of the range hood packaging foam.

[0038] 2. Core mold 13: A detachable core mold 13 is provided in the mold cavity 12 of the front mold 10, and its molding surface is designed into a corresponding shape according to the range hood panel to be packaged. This design enables the mold to adapt to range hood panels of different designs, increasing the versatility and flexibility of the mold.

[0039] 3. Docking area 14 and docking seat 15: In order to ensure the stability and accuracy of the core mold 13 during the molding process, a concave docking area 14 is provided in the cavity of the front mold 10. The core mold 13 is connected to the docking area 14 through the docking seat 15 on its back. This design ensures that the core mold can be accurately fixed in the front mold to avoid displacement when the foaming material is injected to form the packaging foam. Provide connection support for the detachable installation of the core mold.

[0040] 4. Fixing bolts and screw holes: In order to further improve the stability of the core mold 13 during the molding process, the connection surface of the docking seat 15 is provided with screw holes, and the fixing bolts pass through the docking area 14 and are connected to the screw holes. In this way, the core mold 13 can be firmly fixed in the front mold 10, ensuring high stability and repeatability during the production process.

[0041] 5. Injection of foaming material: After the front mold 10 and the rear mold 11 are closed, the range hood packaging foam is formed by injecting the foaming material into the cavity 12. In this process, the shape and position of the core mold 13 determine the final shape of the packaging foam, including key structures such as the positioning column 5, the clamping area 6 and the support column 7.

[0042] 6. Modularity and adjustability of the mold: In this case, by adopting a detachable core mold 13 and designing a docking area 14 in the front mold 10, the molding mold of the present invention not only improves production efficiency, but also has high modularity and adjustability. This means that by replacing the core mold 13 of different shapes or adjusting the position of the core mold, the same mold system can be used to produce packaging foam suitable for different range hood panel designs, greatly reducing mold costs and production costs.

[0043] Compared with the traditional technology, in this case, the detachable core mold is used to mold the protective foam of the panel part of the range hood product. Therefore, when designing and producing different styles of range hood products, the manufacturer only needs to change the design of the panel part, while the main part remains the same. Therefore, when producing the packaging foam of the range hood, only the design of the core mold needs to be changed. Different range hoods can use the core mold with the same mold body to produce packaging foam that matches them. This reduces the cost of users to produce packaging foam, so it can be widely promoted and used.

[0044] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims created by the present invention.
