Technical Field

[0001] The present invention belongs to the technical field of appearance product molding, and particularly relates to a structure for improving sink marks of appearance products. Background Art

[0002] For existing appearance products, due to functional requirements, it is necessary to design a BOSS post structure with a relatively high height and wall thickness. When forming the BOSS post structure, sink marks are likely to appear on the appearance surface of its back, affecting the appearance effect. The conventional improvement method is to embed screws in the BOSS post to solve the sink mark problem, resulting in an increase in processing costs. Summary of the Invention

[0003] The purpose of the present invention is to solve the above technical problems, and provide a structure for improving sink marks of appearance products, so as to ensure the appearance of the product and the normal mold opening of the product without adding auxiliary parts. To achieve the above purpose, the technical solution of the present invention is as follows:

[0004] A structure for improving sink marks of appearance products includes an arc plate body, a plurality of BOSS post assemblies circumferentially arranged on the concave inner surface of the arc plate body, and a rib position assembly for positioning the arc plate body to a corresponding installation position; the BOSS post assembly includes an arched bracket connecting the arc plate body, a positioning post arranged at the top of the arched bracket, and a substrate arranged inside the arched bracket and connecting the positioning post and the arc plate body, and the thickness of the substrate is less than 1 / 2 of the thickness of the arc plate body.

[0005] Specifically, the arc surface of the arc plate body is a smooth surface, and the four corners of the arc plate body are rounded corners.

[0006] Specifically, first reinforcing ribs are arranged on the arched bracket on both symmetric sides of the positioning post.

[0007] Specifically, second reinforcing ribs are also arranged on the outside of the substrate on the side of the positioning post, and the second reinforcing ribs and the two first reinforcing ribs form a relatively perpendicular position.

[0008] Specifically, the rib position assembly includes a plurality of transverse baffles horizontally arranged on the arc plate body and a longitudinal baffle longitudinally connecting the plurality of transverse baffles.

[0009] Specifically, a plurality of equally spaced first branch baffles are arranged on the transverse baffle at one end edge of the arc plate body.

[0010] Specifically, a plurality of second branch baffles are arranged on the opposite side edges of the arc plate body.

[0011] Specifically, the first reinforcing rib in one BOSS post assembly is located on the longitudinal baffle.

[0012] Compared with the prior art, the beneficial effects of the structure for improving sink marks of the appearance product of the present invention are mainly reflected in:

[0013] By arranging a substrate and an arched bracket at the bottom of the positioning post, the glue is effectively separated, avoiding the problem of sink marks during mold opening caused by excessive thickness at the root of the positioning post; the arched bracket forms an undercut through internal glue separation, and the undercut is positioned by an inclined stop block during mold opening, with strong ejection force, ensuring the appearance quality of the product. Without the need to additionally increase auxiliary components, normal mold opening can be achieved; the overall arc-shaped plate body structure ensures that the arc-shaped outer surface of the product is smooth and the rib position components in the arc-shaped concave inner surface are accurately positioned.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Embodiment:

[0023] Referring to Figures 1-4 As shown, this embodiment is a structure for improving sink marks of an appearance product, including an arc-shaped plate body 1, a plurality of BOSS post assemblies 2 circumferentially arranged on the concave inner surface of the arc-shaped plate body 1, and a rib position component 3 for positioning the arc-shaped plate body 1 to a corresponding installation position.

[0024] The arc-shaped surface of the arc-shaped plate body 1 is a smooth surface, and the four corners of the arc-shaped plate body 1 are rounded corners.

[0025] The BOSS post assembly 2 includes an arch-shaped bracket 21 connected to the arc plate body 1, a positioning post 22 provided at the top of the arch-shaped bracket 21, and a base plate 23 provided inside the arch-shaped bracket 21 and connecting the positioning post 22 and the arc plate body 1. The thickness of the base plate 23 is less than 1 / 2 of the thickness of the arc plate body 1.

[0026] Referring to Figure 5 As shown, the opening of the positioning post 22 is arranged outward, and the height of the positioning post 22 is 10 - 11 mm. The thickness of the base plate 23 is 1.21 - 1.22 mm. The thickness of the arc plate body 1 is 2.5 - 2.6 mm.

[0027] On both symmetric sides of the positioning post 22, there are first reinforcing ribs 4 located on the arch-shaped bracket 21. On the side of the positioning post 22, there is also a second reinforcing rib 5 located outside the base plate 23. The second reinforcing rib 5 and the two first reinforcing ribs 4 form a relatively perpendicular position.

[0028] The rib position assembly 3 includes a plurality of transverse baffles 31 horizontally arranged on the arc plate body 1 and a longitudinal baffle 32 longitudinally connecting the plurality of transverse baffles 31. On the transverse baffle 31 at one end edge of the arc plate body 1, there are a plurality of equally spaced first branch baffles 6. On the opposite side edges of the arc plate body 1, there are a plurality of second branch baffles 7.

[0029] The first reinforcing rib 4 in one BOSS post assembly 2 is located on the longitudinal baffle 32.

[0030] When applying this embodiment, by arranging the base plate 23 and the arch-shaped bracket 21 at the bottom of the positioning post 22, effective glue separation is achieved, avoiding the problem of mold shrinkage marks caused by excessive thickness at the root of the positioning post 22; an undercut is formed by glue separation inside the arch-shaped bracket 21, and the undercut is positioned for mold opening through an inclined block (not shown in the figure), with strong ejection force, ensuring the appearance quality of the product. Without the need to additionally add auxiliary components, normal mold opening can be achieved; the overall arc plate body structure ensures that the arc outer surface of the product is smooth and the rib position assembly inside the arc concave inner surface is accurately positioned.

[0031] The above are only some embodiments of the present invention. For those of ordinary skill in the art, without departing from the inventive concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
