Description

Technical Field

[0001] The utility model belongs to the technical field of automobile decoration, and in particular relates to a novel interlocking rib structure of an injection molded part. Background Art

[0002] Rib structures play a very important role in the design and manufacture of injection molded products. Rib structures can increase the strength of injection molded parts, prevent deformation or rupture due to excessive force during use, and enable them to withstand greater loads and stresses. The application of injection molded part limit rib structures can improve the stability and precision of injection molded parts, so that they can maintain their original shape and size when subjected to external forces; through precise design and manufacture of rib structures, the size and shape accuracy of injection molded parts can be improved. During the injection molding process, the shrinkage of plastic materials can be effectively controlled to prevent deformation of injection molded parts during cooling. The rigidity of injection molded parts can be improved so that they can maintain good performance when subjected to external forces.

[0003] The limiting rib structures commonly used in automotive interior products often have a single limiting function, and most of them appear in pairs to limit other parts. For a single part, a set of rib structures can only limit one direction of the part, and the two are often distributed far apart. For the face difference of the matching part, other structures need to be designed to limit it. In the assembly process of two parts, there are often strict requirements for face difference. In view of this, a new type of interlocking rib structure for injection molded parts is urgently needed in the industry. Utility Model Content

[0004] The purpose of the utility model is to design a novel interlocking rib structure for injection molded parts which can not only limit the position of parts, but also limit the surface difference of two parts at the fitting place, so that a pair of ribs can be distributed on different parts, and the position and surface difference of the parts after assembly can be controlled simultaneously; the problem that multiple groups of rib positions need to be matched to realize the simultaneous control of position and surface difference is solved.

[0005] The technical problem solved by the utility model is achieved by adopting the following technical solutions:

[0006] A novel interlocking rib structure of injection molded parts, which consists of an armrest storage box 1, an armrest frame 2, an armrest lower cover 3, an armrest storage box rib 4 and an armrest lower cover rib 5. The armrest storage box 1 is connected to the armrest frame 2 by welding; the armrest lower cover 3 is connected to the armrest frame 2 by snapping; the armrest storage box 1 is provided with an armrest storage box rib 4; the armrest lower cover 3 is provided with an armrest lower cover rib 5.

[0007] The armrest storage box rib 4 is grooved, and the groove is 1.61 mm wide in the Y direction. The top of the armrest lower cover rib 5 is provided with an elongated structure, and its size is 1.52 mm wide in the Y direction. The elongated structure is inserted into the groove of the armrest storage box rib, which not only limits the position of the armrest lower cover in the Y direction, but also realizes the control of the surface difference between the armrest storage box and the armrest lower cover.

[0008] The interlocking ribs designed in the utility model have mutual effects at the assembly of two parts, which can not only limit the position of each other, but also limit the surface difference of the mating surfaces. The interlocking ribs are small and easy to implement in the mold. For the position with both limit requirements and surface difference requirements, the reasonable arrangement of the rib structure can reduce the cost of mold manufacturing.

[0009] The advantages and positive effects of the utility model are:

[0010] This new type of limiting rib structure has a small structure and is easy to form. It has a reinforcing effect on the part itself. More importantly, it can control the part surface difference while controlling the part position. BRIEF DESCRIPTION OF THE DRAWINGS
