Description

Technical Field

[0001] The present application relates to the technical field related to television accessories, and in particular to a fully plastic-wrapped television base and a production method for the fully plastic-wrapped television base. Background Art

[0002] As people's quality of life continues to improve, their demands for the sophistication and reliability of home appliances are also increasing. As an essential home appliance, the base of a TV set must not only have a beautiful and exquisite appearance, but also be strong enough to support the weight of the TV.

[0003] In the prior art, the base includes a connecting seat portion for connecting to a television set and a supporting leg portion connected to the connecting seat portion to form an integral structure. The base is divided into an aluminum alloy base and a plastic base. The aluminum alloy base has better strength, and its supporting leg portion and connecting seat portion can be made thinner and less prone to rust. It also has a more beautiful metallic texture than other commonly used metals (such as steel plates). However, the production cost of the aluminum alloy TV base is very high and the production efficiency is low. This is because: after the aluminum alloy base is formed, in order to improve the surface texture, it needs to be ground and polished, and then electroplated or painted. The production conditions are poor, the labor cost is high, and the efficiency is low. Because the grinding and polishing are difficult to control, the scrap rate of the products produced is also high, which in turn causes the problem of high cost. Therefore, it can only be used on high-end televisions.

[0004] The other type is a plastic base, which has a lower production cost, but the plastic strength is poor. In order to have sufficient strength to support the TV, the supporting legs and the connecting seat are made thicker or thicker, or reinforcing rib structures need to be added, which results in a poor sense of refinement and is usually used on low-end TVs.

[0005] Therefore, how to ensure that the TV base has high strength and exquisiteness while avoiding the high cost problem caused by using aluminum alloy materials has become an important technical problem to be solved by those skilled in the art. Summary of the Invention

[0006] The present invention aims to provide a fully plastic-clad television base that, while maintaining high strength, is thinner and more compact than conventional plastic TV bases and has a lower production cost than conventional aluminum alloy TV bases.

DETAILED DESCRIPTION

[0042] To make the objectives, technical solutions, and advantages of the present invention more apparent, the technical solutions of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other implementations obtained by those of ordinary skill in the art without inventive effort are within the scope of protection of the present invention.

[0043] The present embodiment aims to provide a fully plastic-clad TV stand that, while maintaining high strength, is thinner and more compact than conventional plastic TV stands and has a lower production cost than conventional aluminum alloy TV stands. This embodiment also provides a method for producing the fully plastic-clad TV stand.

[0044] The following embodiments are described with reference to the accompanying drawings. The embodiments described below do not limit the invention as set forth in the claims. Furthermore, the entire contents of the configurations shown in the following embodiments are not necessarily required to serve as solutions to the invention as set forth in the claims.

[0045] See also Figures 1-8 The fully plastic-wrapped TV base provided in this embodiment includes three parts: a metal inner frame 17 , a first injection-molded part 11 and a second injection-molded part 18 .

[0046] Among them, since steel has the characteristics of low cost and high strength, the material of the metal inner frame 17 in this embodiment is preferably steel, and the metal inner frame 17 can be formed by stamping a plate. Of course, in other embodiments, alloy materials can also be used and formed by other processes, such as a die-casting process. The metal inner frame 17 includes a first supporting leg 16 and a first connecting seat 15, wherein the first supporting leg 16 can be specifically two, the first connecting seat 15 is arranged between the two supporting legs and the three are an integrated structure, the first connecting seat 15 is used to connect to the TV body, and specifically a connecting hole can be stamped out in the first connecting seat 15, and connected to the TV body by a connector inserted into the connecting hole.

[0047] In this embodiment, the first injection-molded part 11 is an injection-molded plastic part having a positioning structure, which allows the metal inner frame 17 to be positioned and connected to the first injection-molded part 11. The second injection-molded part 18 is also an injection-molded plastic part. During the injection molding process, the second injection-molded part 18 can be simultaneously molded into an integrated structure with the first injection-molded part 11. The first injection-molded part 11 and the second injection-molded part 18 are connected to form a structure that completely encloses the metal inner frame.

[0048] It should be noted that this embodiment employs two injection molded parts. The first injection molded part 11 is provided with a positioning structure. After the metal inner frame 17 is fixedly mounted on the first injection molded part 11 via the positioning structure, the first injection molded part 11 and the metal inner frame 17 can be placed together in the injection mold for secondary injection molding, forming a second injection molded part 18 that is integral with the first injection molded part 11. Furthermore, the first injection molded part 11 and the second injection molded part 18 together enclose the metal inner frame 17. Because the positioning structure is provided on the first injection molded part 11, the metal inner frame 17 can be positioned on the first injection molded part 11. When placed in the injection mold, the first injection molded part 11 also supports the metal inner frame 17, allowing for secondary injection molding to form the second injection molded part 18. Without the first injection molded part 11, the metal inner frame 17 cannot be suspended in the mold cavity of the injection mold, and thus cannot be completely enclosed by injection molding. The TV base structure provided in this embodiment has two injection molded parts. The first injection molded part 11 also plays the role of supporting the metal inner frame 17 in the mold cavity, so that the metal inner frame 17 can be completely covered by the injection molded parts. The injection molding state of the second injection molded part 18 is as follows: Figure 7 and Figure 8As shown, the injection mold has a cavity 22 and a core 21. After the first injection molded part and the metal inner frame 17 are placed in the cavity 22 of the injection mold, liquid plastic is injected into the cavity 22 through the hot runner inlet to form the second injection molded part 18.

[0049] With such a configuration, the TV base provided in this embodiment can greatly save costs during mass production. Moreover, it has a metal inner frame 17 with sufficient strength. The metal inner frame 17 does not require surface grinding, polishing, electroplating or painting processes, and has low production costs. It has sufficient strength without the aid of reinforcing ribs, and at the same time, its size can be thinner and thinner than a plastic TV base, giving it a strong sense of refinement.

[0050] It should be noted that the technical solution provided by the present invention does not specifically limit the shape, weight, size and quantity of the first injection-molded part 11. It only needs to be able to position the metal inner frame 17, be supported in the mold cavity of the injection mold, and be able to be injection-molded with the second injection-molded part 18 to form an integrated structure of the TV base that can completely cover the metal inner frame 17.

[0051] In this embodiment, the positioning structure can be specifically a positioning protrusion 24 provided on the first injection molded part 11, such as Figure 8 As shown, the metal inner frame 17 is provided with corresponding positioning grooves, and the positioning protrusions 24 cooperate with the positioning grooves, thereby achieving positioning between the first injection molded part 11 and the metal inner frame 17. Of course, in other embodiments, the positioning structure can also be specifically provided as positioning grooves provided on the first injection molded part 11, and the corresponding positioning protrusions are provided on the metal inner frame 17.

[0052] In addition, it should be noted that Figure 8 In the embodiment, the positioning protrusion 24 is set at a position corresponding to the first connecting seat portion of the first injection molded part 11 and the metal inner frame 17. In other embodiments, the positioning protrusion or positioning groove can also be set at other positions. For example, it can be set at a position corresponding to the first support leg portion of the first injection molded part 11, or it can be set at a position corresponding to the first connecting seat portion and a position corresponding to the first support leg of the first injection molded part 11 at the same time. The specific setting can be based on actual conditions.

[0053] In another embodiment of this solution, Figure 1As shown, the first injection molded part 11 includes a second support leg 12 and a second connecting seat 14, which are injection-molded into an integral structure. The second support leg 12 corresponds to the first support leg 16 of the metal inner frame 17, and the second connecting seat 14 corresponds to the first connecting seat 15 of the metal inner frame 17. The second injection molded part 18 includes a third support leg 20 corresponding to the first support leg 16 and a third connecting seat 19 corresponding to the first connecting seat. The third support leg 20 and the third connecting seat 19 are an integral structure formed by injection molding. That is, the metal inner frame 17, the first injection molded part 11, and the second injection molded part 18 are identical in shape and structure. Moreover, after being injection-molded into an integral structure, the first injection molded part 11 and the second injection molded part 18 are able to completely cover all corresponding parts of the metal inner frame 17. On this basis, the positioning structure of the first injection molded part 11 can be set as a groove structure 13 extending along the second support leg 12, that is, a groove structure 13 is provided on the second support leg 12 of the first injection molded part 11, and the extension direction of the groove structure 13 is consistent with the extension direction of the second support leg 12, such as Figure 1 As shown, the first support leg 16 of the metal inner frame 17 can be inserted into the groove structure 13. The width of the groove structure 13 only needs to be sufficient to clamp the first support leg 16. In this configuration, the groove structure 13 can partially cover the metal inner frame 17 and can effectively position the metal inner frame 17. When the second injection molded part 18 is injected, the groove structure 13 can be completely sealed by the second injection molded part 18.

[0054] Furthermore, it should be noted that the TV base provided in this embodiment, unlike the prior art, can be manufactured in different colors or materials, further enhancing the quality of the TV base. For example, the first injection molded part 11 and the second injection molded part 18 can be molded using different colored materials, resulting in the final product having two different colors. Of course, in other embodiments, the first injection molded part 11 and the second injection molded part 18 can also be made of the same color and material.

[0055] This specific embodiment also provides a method for producing a fully plastic-wrapped television base, comprising:

[0056] A metal inner frame 17 is formed, and a first injection molded part 11 is formed by injection molding, wherein a positioning structure for positioning the metal inner frame 17 is formed on the first injection molded part 11;

[0057] The metal inner frame 17 is fixedly mounted on the first injection molded part 11 through a positioning structure;

[0058] Put the metal inner frame 17 and the first injection molded part 11 into the injection mold together, so that the metal inner frame is positioned in the injection mold by the first injection molded part 11;

[0059] The second injection molded part 18 is formed by injection molding, and the first injection molded part 11 and the second injection molded part 18 are connected to form an integrated structure by injection molding. The first injection molded part 11 and the second injection molded part 18 completely cover the metal inner frame 17 together. Figure 7 and Figure 8 As shown, the injection mold has a cavity 22 and a core 21. After the first injection molded part and the metal inner frame 17 are placed in the cavity 22 of the injection mold, liquid plastic is injected into the cavity 22 through the hot runner inlet to form the second injection molded part 18.

[0060] It should be noted that the positioning structure can be a positioning groove or a positioning protrusion. For details, please refer to the positioning protrusion 24 of the first injection molded part 11 in the above embodiment, which will not be described in detail here. Similarly, the metal inner frame 17 in the above method can also be a stamped steel plate structure or a die-cast alloy structure.

[0061] With this arrangement, the method for producing a fully plastic-encased TV base provided by the present invention can simply completely enclose the metal inner frame 17, overcoming the difficulty of suspending the metal inner frame 17 within the mold cavity. This significantly reduces costs during mass production. Furthermore, the metal inner frame 17 is sufficiently strong, requiring no surface treatment, resulting in lower production costs. The metal inner frame 17 possesses sufficient strength without the need for reinforcing ribs, and can be made thinner and more refined than a plastic TV base.

[0062] It should be noted that the production method of the fully plastic-coated TV base provided by the present invention can also be implemented by a two-color injection molding machine, and the specific steps include:

[0063] Forming a metal inner frame, forming a first injection molded part by injection molding using a two-color injection molding machine, and forming a positioning structure for positioning the metal inner frame on the first injection molded part;

[0064] After the two-color injection molding machine completes the injection molding of the first injection molded part, the mold is opened, the dynamic mold side turntable of the two-color injection molding machine rotates 180 degrees, the metal inner frame is placed into the mold cavity, and the metal inner frame is fixed to the first injection molded part through the positioning structure, and the core side of the first injection mold is matched with the cavity side of the second injection mold;

[0065] The two-color injection molding machine closes the mold for secondary injection molding to form a second injection molded part, and the first injection molded part and the second injection molded part are connected to form an integrated structure through injection molding. The first injection molded part and the second injection molded part together completely cover the metal inner frame.

[0066] Using a two-color injection molding machine for production, you can produce two different colors or materials of the covering shell. Of course, you can also produce the same color or the same material of the covering shell, the specific setting can be based on actual conditions.

[0067] It is understood that the same or similar parts of the above embodiments can be referenced to each other, and the details not described in detail in some embodiments can be referred to the same or similar contents in other embodiments. The multiple solutions provided by the present invention include their own basic solutions, which are independent of each other and do not restrict each other. However, they can also be combined with each other to achieve multiple effects without conflict.

[0068] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
