Description

Technical Field

[0001] The utility model relates to the mature field of plastic injection molding, in particular to a buckle rib structure. Background Art

[0002] Spray-free plastics are made by adding powders with different display effects, such as metal powder, pearl powder, ceramic powder, high-gloss color powder, etc., to plastic raw materials (PP, ABS, AS, PC, etc.) through melt blending, so that they have special color effects. Spray-free materials usually include parts with smooth surfaces, which can be injection molded to produce a better appearance, but conventional structures such as rib positions will affect the smooth flow of injection molding filling, causing changes in the flow direction of powders, causing aggregation, and thus causing poor appearance.

[0022] In order to make the technical problems, technical solutions and beneficial effects solved by the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] A buckle rib structure comprises a shell 1 and a rib 2 which are integrally injection molded, wherein the shell 1 comprises a main wall 11, the rib 2 is protrudingly arranged on the main wall 11, the rib 2 comprises a main body 21, the length direction of the main body 21 is consistent with the plastic flow direction when the main body 21 is injection molded, and a through groove 22 penetrating the main body 21 is provided on the rib 2 to form a gap 23 between the main body 21 and the main wall 11, and the penetration direction of the through groove 22 is perpendicular to the plastic flow direction.

[0024] The utility model provides a buckle rib structure. After the through groove is set, during injection molding, a part of the plastic flows along the direction of the main wall, and the other part flows along the length direction of the rib after entering the rib. The two directions are the same, which can accelerate the flow of the plastic and avoid aggregation at the rib, resulting in powder aggregation. The rib on the main wall is a raised structure, so that when the plastic flows to form the main wall, it gathers on the rib and does not flow. At the same time, the gap can reduce the thickness of the main wall at the position corresponding to the rib, avoiding the shrinkage phenomenon caused by different thickness of the main wall.

[0025] Furthermore, as a preferred embodiment of the present invention but not limiting, the width of the gap 23 is less than one third of the thickness of the main wall 11. This can effectively maintain the strength of the ribs and avoid the aggregation of powder.

[0026] Further, as a preferred embodiment of the present solution but not a limitation, the rib 2 includes a first connecting portion 24 connecting the head end of the main body 21 and the main wall 11, and the thickness of the first connecting portion 24 gradually increases from the main wall 11 along the plastic flow direction until it is flush with the main body 21. This is conducive to the plastic flowing smoothly into the main body.

[0027] Further, as a preferred embodiment of the present solution but not a limitation, the rib 2 includes a second connection portion 25 connecting the end of the main body 21 and the main wall 11, and the thickness of the second connection portion 25 gradually decreases from the main body 21 along the plastic flow direction until it is flush with the main wall 11. This is conducive to the plastic flowing out of the main body smoothly.

[0028] Further, as a preferred embodiment of the present invention but not limiting, the rib 2 further comprises a side rib 26, and the side rib 26 gradually approaches the main wall 11 from the main body 21 along the plastic flow direction. The side rib is beneficial to strengthen the strength of the rib. And its inclined setting is beneficial to the inflow and outflow of plastic.

[0029] Further, as a preferred embodiment of the present invention but not limiting, the thickness of the side ribs 26 gradually decreases from the main body 21 toward the side of the main wall 11. This is beneficial to strengthen the strength of the ribs and avoid shrinkage of the shell due to excessive thickness.

[0030] Further, as a preferred embodiment of the present invention but not limiting, a plurality of the side ribs 26 support the main body 21 and divide the through slot 22 into a plurality of the gaps 23. The side ribs support the main body at breakpoints to improve the strength of the ribs.

[0031] Furthermore, as a preferred implementation manner of the present solution but not a limitation, the side rib portion 26 is located on a side of the main body portion 21 close to the side edge of the main wall 11 .

[0032] Further, as a preferred embodiment of the present invention but not limiting, a groove 27 is provided on the side of the main body 21 facing the side rib 26 to prevent the main body and the side rib from being too thick at the connection position.

[0033] The above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application. Other principles and basic structures that are the same or similar to those of the present application are within the protection scope of the present application.
