Description

Technical Field

[0001] This utility model belongs to the field of automotive sunroof glass edging, specifically, this utility model relates to an automotive sunroof edging mold. Background Technology

[0002] To improve the airtightness of automotive sunroof glass and reduce wind noise and rain intrusion during vehicle operation, the sunroof glass is usually edge-wrapped. This is typically achieved by using a first mold and a second mold that work together to form an outer edge edging cavity. The sunroof glass is held between the first mold and the second mold, which are usually clamped together using movable wedges. This results in a certain gap in the outer edge edging cavity, which can easily cause the edging material to overflow, affecting the edging effect of the sunroof glass and leading to waste of edging material.

[0003] To address the aforementioned issues, patent application number 2022212555627 discloses an injection mold for edge wrapping of an automotive sunroof, comprising a first injection mold base and a second injection mold base. The first injection mold base has a first edge wrapping cavity, several pressing and locking mechanisms, and a suction cup mechanism disposed within the inner ring of the first edge wrapping cavity. The suction cup mechanism includes a suction cup carrier and several suction cups arranged in a matrix on the suction cup carrier. The suction cup carrier has a lifting elastic floating displacement. The second injection mold base has a second edge wrapping cavity for cooperating with the first edge wrapping cavity, but this does not solve the aforementioned problems.

[0004] Therefore, in order to improve or solve at least one of the above problems, it is necessary to optimize the existing mold and provide an automotive sunroof edge-wrapping mold that is conducive to reducing edge-wrapping material overflow, avoiding edge-wrapping material waste, and improving the sealing performance of the outer edge-wrapping cavity.

Detailed Implementation

[0024] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings, in order to help those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention, and to facilitate its implementation.

[0025] Figure 1 This is a schematic diagram of the structure of the edge-wrapping mold in an embodiment of this utility model; Figure 2 This is a schematic diagram of the structure of the edge-wrapping mold in an embodiment of this utility model.

[0026] like Figure 1 and Figure 2 As shown, the automotive sunroof edging mold provided by this utility model includes an upper edging mold 10 and a lower edging mold 20 disposed on the upper edging mold 10. An overflow unit 30 is provided between the upper edging mold 10 and the lower edging mold 20. The overflow unit 30 can reduce the amount of edging material overflow, which helps to avoid waste of edging material, improves the sealing performance of the outer edge edging cavity between the upper edging mold 10 and the lower edging mold 20, and improves the edging effect of the automotive sunroof glass. Therefore, the automotive sunroof edging mold provided by this utility model helps to reduce the overflow of edging material, avoid waste of edging material, improve the sealing performance of the inner and outer edge edging cavities of the automotive sunroof edging mold, and improve the edging effect of the automotive sunroof glass.

[0029] like Figure 3 and Figure 4 As shown, the overflow unit 30 includes a first flange 31 disposed on the lower edge-wrapping mold 20, and a second flange 32 disposed on the upper edge-wrapping mold 10. The first flange 31 and the second flange 32 are adapted to each other. Through the mutual abutment and cooperation of the first flange 31 and the second flange 32, it is possible to improve the convenience of limiting and clamping the upper edge-wrapping mold 10 and the lower edge-wrapping mold 20, ensure the accuracy when the first edge-wrapping groove 11 and the second edge-wrapping groove 21 are spliced ​​to form the outer edge-wrapping cavity, which is conducive to reducing the overflow of edge-wrapping material, avoiding waste of edge-wrapping material, improving the sealing performance of the outer edge-wrapping cavity, and improving the edge-wrapping effect of automotive sunroof glass.

[0030] Figure 5 yes Figure 1 A magnified view of part C in the middle; Figure 6 This is a schematic diagram of the rear sunroof slider in an embodiment of this utility model.

[0031] like Figure 5 and Figure 6As shown, the overflow unit 30 also includes an installation groove 33 disposed in the lower edge-wrapping mold 20. A rear sunroof slider 34 is disposed within the installation groove 33. A slider flange 35 is provided on the rear sunroof slider 34, and a third edge-wrapping groove 36 is provided on the slider flange 35. The third edge-wrapping groove 36, together with the first edge-wrapping groove 11 and the second edge-wrapping groove 21, forms an outer edge-wrapping cavity, which helps reduce edge-wrapping material overflow, avoids waste of edge-wrapping material, further improves the airtightness of the automotive sunroof glass, reduces wind noise and rainwater intrusion during vehicle operation, and improves the overall NVH performance of the vehicle. After edge-wrapping treatment, when the upper edge-wrapping mold 10 and the lower edge-wrapping mold 20 are opened, the rear sunroof slider 34 will move first, creating a gap between the edge-wrapped automotive sunroof glass and the mold, reducing demolding resistance, avoiding damage to the edge or glass during demolding, facilitating the smooth removal of the molded automotive sunroof glass, and improving production efficiency and product quality.

[0032] The slider flange 35 is provided with an overflow groove 37 and an overflow protrusion 38. The overflow groove 37 and the overflow protrusion 38 can form a specific shape and structure for the sunroof glass edge during the process of edging the automotive sunroof glass, ensuring that the edge is perfectly matched with the installation parts of the glass and the body.
