[0002] In the automotive manufacturing industry, molds are required to manufacture steering wheels. High requirements are placed on steering wheels, ensuring the comfort and appearance of the square wheel surface while also ensuring smooth and efficient glue injection during the production process. During the manufacturing process, to ensure that the glue injection point does not appear on the exterior surface, a tab feature needs to be added to the mold to facilitate glue injection. However, the glue injection feature on traditional glue injection molds is concave and located at the steering wheel handle, requiring a longer tab, which makes ejection difficult and inconvenient. Furthermore, the connection between the tab and the product is thick, leaving a dent on the product surface and reducing the product's aesthetics. Utility Model Content

[0003] In order to solve the above technical problems, the utility model provides a steering wheel glue injection mold to solve the technical problems in the existing technology that the traditional glue injection mold requires the use of a longer vertical piece, which makes the vertical piece difficult to eject and inconvenient to process; at the same time, the connection between the vertical piece and the product is thick, resulting in dents on the product, which reduces the aesthetics.

[0004] The purpose and effect of the mold for gluing a steering wheel in the utility model are achieved by the following specific technical means:

[0023] The following embodiments of the present invention are described in further detail with reference to the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0024] Example:

[0025] As attached Figure 1 To the attached Figure 5 As shown:

[0026] The utility model provides a steering wheel glue injection mold, including an A plate 11 and a B plate 12, a front mold core 13 is clamped in the groove at the bottom of the A plate 11, a rear mold core 14 is clamped in the groove at the top of the B plate 12, and a glue injection component is provided on the top of the rear mold core 14, and the glue injection component includes a hanging piece 31, a hanging piece through groove 32 is opened on the top of the rear mold core 14, the hanging piece 31 is passed through the hanging piece through groove 32, and the top of the hanging piece 31 is connected to the inner side of the product 15, shortening the length of the hanging piece 31 relative to the product 15, making it easier to detach when ejecting the product 15, avoiding the problem of difficult ejection of the hanging piece in the traditional mold; it is worth mentioning that the present invention The mold also optimizes the connection between the tab 31 and the product 15. Traditional thicker connection parts are prone to leave obvious dents on the surface of the finished product, affecting the appearance. The mold makes the connection thinner, which not only ensures product quality but also effectively avoids the occurrence of surface defects. At the same time, the bottom of the tab 31 is also thickened to meet the actual needs of glue filling, and achieves a balance between appearance requirements and process requirements; in addition, a tab straight top assembly is also provided at the bottom of the rear mold core 14, which contacts the bottom of the tab 31. When the product 15 is ejected, it can ensure that the tab 31 is ejected from the mold together with the product 15, thereby improving production efficiency.

[0027] Please refer to Figure 3 and Figure 4 As shown, the glue inlet assembly also includes a glue inlet channel 33. A flow channel groove 34 is correspondingly provided on one side of the rear mold core 14 adjacent to the front mold core 13. The glue inlet channel 33 is provided in the flow channel groove 34, ensuring that the raw material flows smoothly into the mold cavity through the glue inlet channel 33, laying the foundation for subsequent injection molding; a glue inlet diving port 35 is provided at one end of the glue inlet channel 33, and a through groove connected to the vertical piece through groove 32 is provided on the top of the rear mold core 14. The other end of the glue inlet diving port 35 passes through the through groove and is connected to the vertical piece 31, so that the raw material can be directly injected into the vertical piece 31, ensuring the pouring quality, which is conducive to improving the consistency and stability of the finished product.

[0028] Please refer to Figure 5 As shown, the tab straight top assembly includes a straight top 41, the top of which is inserted into the aforementioned tab through groove 32. More importantly, a groove is formed at the top of the straight top 41, and the tab 31 is located in this groove. The tab 31 and the straight top 41 are integrated together, so that when the product 15 is demoulded, the tab 31 can be taken out of the mold together with the straight top 41. This not only eliminates the tedious steps of manual operation, greatly simplifies the entire process, and improves production efficiency, but also ensures that the tab 31 can maintain good integrity with the product 15. After molding, the final finishing of the product 15 can be easily completed by simply breaking or cutting the tab 31.

[0029] Please refer to Figure 5As shown, the vertical piece straight top assembly also includes a straight top seat 42, the top of which is provided with a T-shaped slot 43, and the bottom of the straight top 41 is provided with a T-shaped hook 44, which is located in the T-shaped slot 43. The bottom of the B plate 12 is provided with a through slot corresponding to the vertical piece through slot 32, and the straight top seat 42 and the straight top 41 are both inserted into this through slot; a guide block 45 is also provided on one side of the straight top seat 42, and the guide block 45 is fixedly connected to the bottom of the B plate 12 by screws.

[0030] Please refer to Figure 2 As shown, at the bottom of the B plate 12, two groups of square irons 16 are fixedly connected, and two groups of slidable ejector plates 17 are arranged between the two groups of square irons 16. The top of one group of ejector plates 17 corresponds to the straight ejector seat 42 and is provided with a through groove, and the bottom end of the straight ejector seat 42 is inserted into this through groove and is fixedly connected to the other ejector plate 17 by a fixing bolt 46; this not only enhances the stability of the entire straight ejector assembly, but also ensures that it can move up and down with the sliding of the ejector plate 17, thereby better cooperating with the demoulding process of the product 15; a bottom plate 18 is also provided at the bottom of the two groups of square irons 16, and the main function of this bottom plate 18 is to provide a solid support platform to ensure that the entire mold structure can withstand various external forces during the production process to avoid deformation or damage.

[0031] Please refer to Figure 2 As shown, a panel 19 is provided on the top of the A plate 11, and a heat insulation board 20 is provided on the top of the panel 19 to reduce the conduction and loss of heat during the operation of the mold and ensure that the temperature inside the mold can be effectively protected and controlled.

[0032] The embodiments of the present invention are provided for purposes of illustration and description and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art.
