[0002] A mold is a tool used to create shaped products. Different shapes of molds are used to create products of different shapes, such as... Figure 1 The nose pad shown is V-shaped and is used to support the middle of the glasses. The nose pad has a T-shaped groove in the middle and is made of soft material. The molded nose pad cannot be directly ejected by ejector pins. Therefore, how to achieve the molding and demolding of the nose pad is a technical problem that urgently needs to be solved. Utility Model Content
[0003] This utility model provides a nose pad forming mold, which aims to solve the technical problems mentioned in the above technical background.
[0004] To achieve the above objectives, the present invention adopts the following technical solution: a nose bridge forming mold, comprising a panel, an upper moving mold, a lower fixed mold, an ejector plate, and a base plate from top to bottom. An upper mold core is embedded at the bottom of the upper moving mold, and the upper mold core has an upper V-shaped groove. A lower mold core is embedded in the lower fixed mold, and the lower mold core has a lower V-shaped groove. A push rod is installed on the ejector plate, and the upper end of the push rod is a T-shaped forming part. The push rod passes upward through the lower fixed mold and the lower mold core, and the forming part is placed in the lower V-shaped groove.
[0005] Furthermore, the depth of the upper V-groove is greater than the depth of the lower V-groove.
[0006] Furthermore, the ejector plate is provided with an insert, the insert having an inverted T-shaped groove, and the lower end of the push rod is configured as an inverted T-shape and placed in the T-shaped groove.
[0007] Furthermore, cooling water channels are provided inside both the upper mold core and the lower mold core.
[0008] Furthermore, the upper mold core has four upper V-grooves, and the lower mold core has four lower V-grooves, with the upper V-grooves and lower V-grooves being configured in a one-to-one correspondence.
[0009] Furthermore, guide posts are provided on the base plate, and guide holes are provided on the ejector plate.
[0010] Compared with the prior art, the beneficial effects of this utility model are:
[0011] This utility model includes, from top to bottom, a panel, an upper moving mold, a lower fixed mold, an ejector plate, and a base plate. An upper mold core with an upper V-groove is embedded at the bottom of the upper moving mold. A lower mold core with a lower V-groove is embedded in the lower fixed mold. A push rod is mounted on the ejector plate, with its upper end forming a T-shaped molding section. The push rod passes upward through the lower fixed mold and the lower mold core, with the molding section positioned in the lower V-groove. When the mold is closed, the upper and lower mold cores close, and the upper and lower V-grooves close to form the cavity for the nose pad. When the mold is opened, the upper and lower mold cores separate, the ejector plate pushes the push rod upward, and the push rod pushes the nose pad out of the lower V-groove. Finally, a forced ejection removes the nose pad from the molding section, thus achieving product molding and demolding. Attached Figure Description

[0028] Example
[0029] Reference Figure 2-5As shown, this utility model discloses a nose bridge forming mold, including a panel 10, an upper moving mold 20, a lower fixed mold 30, an ejector plate 40, and a base plate 50 from top to bottom. An upper mold core 201 is embedded at the bottom of the upper moving mold 20, and the upper mold core 201 has an upper V-shaped groove 2011. A lower mold core 301 is embedded in the lower fixed mold 30, and the lower mold core 301 has a lower V-shaped groove 3011. A push rod 401 is installed on the ejector plate 40. The upper end of the push rod 401 is a T-shaped forming part 4011. The push rod 401 passes upward through the lower fixed mold 30 and the lower mold core 301, and the forming part 4011 is placed in the lower V-shaped groove 3011. Specifically, during mold closing, the upper mold core 201 and lower mold core 301 close, and the upper V-groove 2011 and lower V-groove 3011 close to form a molded cavity. A T-shaped molding part 4011 is placed inside the cavity to mold the T-groove 601 in the middle of the nose pad 60T. In this embodiment, the upper mold core 201 has four upper V-grooves 2011, and the lower mold core 301 has four lower V-grooves 3011. The upper V-grooves 2011 and lower V-grooves 3011 are arranged in a one-to-one correspondence, allowing for the injection molding of four nose pads 60 in one operation, thus improving molding efficiency.
[0030] Reference Figure 2-5 As shown, an insert is provided on the ejector plate 40, and the insert has an inverted T-shaped groove. The lower end of the push rod 401 is also inverted T-shaped and placed in the T-shaped groove, which facilitates the installation of the lower end of the push rod 401 on the ejector plate 40. When the mold opens, the ejector plate 40 pushes the push rod 401 upward, and the push rod 401 pushes the nose support 60 out of the lower V-shaped groove 3011. Then, the nose support 60 is ejected from the T-shaped forming part 4011 by a strong ejection, thus realizing the demolding of the nose support 60. Furthermore, the depth of the upper V-shaped groove 2011 is greater than the depth of the lower V-shaped groove 3011, which makes the clamping force between the nose support 60 and the lower mold core 301 less after molding, and makes it easier for the push rod 401 to push the nose support 60 out of the lower V-shaped groove 3011.
[0031] Reference Figure 2-5 As shown, cooling water channels are provided inside both the upper mold core 201 and the lower mold core 301. The cooling water channels are arranged horizontally in the upper mold core 201 and the lower mold core 301. During mold closing and injection molding, the cooling water channels play a role in accelerating cooling and molding.
[0032] In addition, guide posts 501 are provided on the base plate 50, and guide holes are provided on the ejector plate 40. When the mold is opened, the ejector plate 40 moves vertically up and down along the guide posts 501 to ensure the smooth movement of the ejector plate 40.
[0033] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
