[0001] The utility model relates to the technical field of automobile injection molding parts, in particular to a thermoplastic composite automobile injection molding part. Background Art

[0002] Injection molding is a method of producing industrial products. Products are usually made of rubber injection molding and plastic injection molding, while automotive injection molding is a kind of automotive accessories made by compression molding, transfer molding, and injection molding.

[0003] However, the existing automotive injection molded parts, when being produced, the materials used mainly include plastics made of polypropylene (PP), polyethylene (PE), polyvinyl chloride (PVC), polystyrene (PS), acrylonitrile-butadiene-styrene copolymer (ABS), polycarbonate (PC), polyamide (PA), and polyoxymethylene (POM). These materials are widely used in different parts of automobiles due to their different physical and chemical properties. These materials are molded by injection molds to make complete automotive injection molded parts. However, the functional effects produced by the above materials are largely limited by the processing technology and the proportion of fillers that can be added, and it is difficult to meet the use requirements in actual applications. The automotive injection molded parts produced by processing have single functionality and it is difficult to achieve comprehensive performance improvement, resulting in different functional and morphological properties of the molded automotive injection molded parts, which affects the quality, durability and load-bearing morphological stability of each different injection molded part, and is not conducive to the use of the injection molded parts.

[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a thermoplastic composite automotive injection molding part is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a thermoplastic composite automotive injection molded part to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a thermoplastic composite automotive injection molded part, comprising an injection molded part body, wherein the injection molded part body is integrally formed by processing with a thermoplastic composite part, wherein the thermoplastic composite part is composed of a core material, an upper end plate and a lower end plate, wherein the core material comprises a honeycomb part evenly distributed in the center of the thermoplastic composite part, and a reinforcing core is fitted in the interval gaps of the core material.

[0007] Preferably, the honeycomb components are all rhombus-shaped cylinders that are separated from each other and independently arranged, and the minimum thickness of the rhombus wall of the honeycomb components is ≥ 0.2 mm.

[0008] Preferably, the reinforcing core is arranged in a rhombus shape to fit the surface of the honeycomb component, and the thickness of the reinforcing core can just fill the combined gaps of each honeycomb component.

[0009] Preferably, the upper end plate and the lower end plate are both multi-layer composite plate structures, and the upper end plate and the lower end plate are formed by combining the same structural support plate, functional plate and adhesive plate layer.

[0010] Preferably, adhesive plate layers are fixedly provided at the upper and lower ends of the honeycomb component and the reinforcing core, and a structural support plate is fixedly provided at one side of the adhesive plate layer away from the honeycomb component.

[0011] Preferably, a functional panel is provided on the outer side of the structural support panel, and the functional panel and the structural support panel are also fixed via an adhesive panel layer.

[0012] Preferably, the thickness of the upper end plate and the lower end plate is ≤45 mm, and the functional plate is one of a flame retardant layer, an anti-ultraviolet layer, a color layer, a wear-resistant layer, an antibacterial layer or a sound insulation layer, or a combination of multiple different layers.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model uses the arrangement of thermoplastic composite parts, core materials, honeycomb parts and reinforcing cores, and utilizes the rhombus shape of the honeycomb parts and the reinforcing cores to improve the overall middle strength of the thermoplastic composite parts. At the same time, the hollow shape of the middle of the honeycomb parts also reduces the overall weight of the thermoplastic composite parts, making the main body of the injection molded parts lighter, and light, high-strength, high-durability, and strong mechanical properties, which greatly improves the morphological stability of the main body of the injection molded parts.

[0015] 2. The utility model arranges an upper end plate, a lower end plate, a structural support plate, a functional plate and an adhesive plate layer. Both the upper end plate and the lower end plate adopt a multi-plate layer structure and include a structural support plate for bearing loads and at least one layer of functional plates. This allows the thermoplastic composite part to be added with various corresponding functional plates according to different usage scenarios of the injection molding body, effectively meeting the diversified needs of the injection molding body in practical applications, greatly improving the practicality and durability, protection and service life of the injection molding body made of thermoplastic composite parts, and the functional plate and the structural support plate are independent of each other, so that the different functional effects of the functional plate are significantly highlighted, avoiding the shortcomings of the functional plate being limited by the proportion of functional filling materials that can be added in the structural support plate and the difficulty in evenly laying.

[0022] like Figure 1-Figure 3 As shown, a thermoplastic composite automotive injection molded part includes an injection molded part body 1. The injection molded part body 1 is formed by a thermoplastic composite part 2 as a whole. The thermoplastic composite part 2 is composed of a core material 21, an upper end plate 22 and a lower end plate 23. The core material 21 includes a honeycomb part 211 evenly distributed in the center of the thermoplastic composite part 2, and a reinforcing core 212 is fitted in the interval gaps of the core material 21.

[0023] By adopting the above technical solution, the honeycomb component 211 and the reinforcing core 212 make the morphological strength of the entire thermoplastic composite component 2 higher.

[0024] Furthermore, the honeycomb components 211 are all rhombus-shaped cylinders that are separated from each other and independently arranged, and the minimum thickness of the rhombus wall of the honeycomb component 211 is ≥0.2 mm.

[0025] By adopting the above technical solution, the middle part of the rhombus-shaped cylindrical honeycomb member 211 is hollowed out, which reduces its own weight while providing support.

[0026] Furthermore, the reinforcing core 212 is arranged in a rhombus shape to fit the surface of the honeycomb component 211 , and the thickness of the reinforcing core 212 can just fill the combined gaps of each honeycomb component 211 .

[0027] By adopting the above technical solution, the reinforcing core 212 fills and supports the gaps between the honeycomb components 211 , thereby preventing the thermoplastic composite material component 2 from sinking in the gaps of the honeycomb components 211 .

[0028] like Figure 2-Figure 4As shown, the upper end plate 22 and the lower end plate 23 are both multi-layer composite plate structures, and the upper end plate 22 and the lower end plate 23 are formed by combining the same structural support plate 231, functional plate 232 and adhesive plate layer 233.

[0029] By adopting the above technical solution, the upper end plate 22 and the lower end plate 23 make the upper and lower surfaces of the thermoplastic composite material part 2 more flat.

[0030] Furthermore, adhesive plate layers 233 are fixedly disposed on the upper and lower ends of the honeycomb component 211 and the reinforcing core 212 , and a structural support plate 231 is fixedly disposed on one side of the adhesive plate layer 233 away from the honeycomb component 211 .

[0031] By adopting the above technical solution, the adhesive plate layer 233 enables the core material 21 to be fixedly connected with the upper end plate 22 and the lower end plate 23 to form a complete thermoplastic composite material part 2.

[0032] Furthermore, a functional panel 232 is disposed on the outer side of the structural support panel 231 , and the functional panel 232 and the structural support panel 231 are also fixed via an adhesive panel layer 233 .

[0033] By adopting the above technical solution, the structural support plate 231 is used to bear the weight of the external load.

[0034] Furthermore, the thickness of the upper end plate 22 and the lower end plate 23 is ≤45 mm, and the functional plate 232 is one of a flame retardant layer, an anti-ultraviolet layer, a color layer, a wear-resistant layer, an antibacterial layer or a sound insulation layer, or a combination of multiple different layers.

[0035] By adopting the above technical solution, the functional plate 232 enables the thermoplastic composite material part 2 to be added with various corresponding functional plates 232 according to different usage scenarios of the injection molded part body 1.

[0036] Working principle: When using the thermoplastic composite automotive injection molded part, first, the injection molded part body 1 is formed by integrally die-casting the thermoplastic composite part 2. When the thermoplastic composite part 2 is selected, the outer functional plate 232 is adjusted according to the specific different usage conditions of the injection molded part body 1. After the injection molded part body 1 is formed by die-casting the thermoplastic composite part 2, the rhombus shape of the honeycomb part 211 and the reinforcing core 212 in the thermoplastic composite part 2 are used to improve the overall middle strength of the thermoplastic composite part 2. At the same time, the honeycomb part The hollow shape of the middle part 211 also reduces the overall weight of the thermoplastic composite part 2, making the injection molded part body 1 lighter, and light, high-strength, highly durable, and strong in mechanical properties. The upper end plate 22 and the lower end plate 23 both adopt a multi-layer structure, and include a structural support plate 231 for bearing the load, and the injection molded part body 1 adds corresponding functional plates 232 according to different usage scenarios, effectively meeting the diversified needs of the injection molded part body 1 in actual applications and the structural form of the injection molded part body 1. This is the working principle of the thermoplastic composite automotive injection molded part.
