Description

Technical Field

[0001] The utility model relates to an inner lining structure, in particular to a novel inner lining for a blow-molded pipe orifice. Background Art

[0002] With the rapid development of my country's automobile industry, the requirements for vehicle performance are getting higher and higher. Automobiles have more and more functions, more and more engine compartment parts, and smaller and smaller assembly space. Therefore, the requirements for assembly flexibility are getting higher and higher. Due to process limitations, traditional hoses and injection molding structures cannot realize complex intake system pipes. Therefore, there are more and more intake pipes with blow molding structures. Due to the particularity of the process, the wall thickness of the blow molding structure is uneven. In order to ensure product quality, linings must be added to improve the strength of the pipe mouth. Traditional linings are all made of metal materials, which are expensive and heavy. Utility Model Content

[0003] In order to solve the above problems, the utility model aims to provide a novel blow molding pipe orifice lining.

[0004] To achieve the above-mentioned purpose, the technical solution of the utility model is: a new type of blow-molded pipe orifice lining, including an outer sleeve and an inner sleeve supported in the outer sleeve, the inner sleeve is shorter than the outer sleeve, and the outer side wall of the inner sleeve is provided with a plurality of support plates arranged around the inner sleeve, so that the inner sleeve is supported in the outer sleeve by the support plates to form an ice-breaking structure.

[0005] Furthermore, each support plate is a right-angled trapezoidal structure, and the lower base of the right-angled trapezoidal structure is fixedly connected to the inner side wall of the outer bushing, and the upper base of the right-angled trapezoidal structure is fixedly connected to the outer side wall of the inner bushing.

[0006] Furthermore, the outer bushing, the inner bushing and the support plate are integrally formed by injection molding or by 3D printing. An annular inclined surface structure is arranged on the outer edge of the plug-in end of the outer bushing.

[0007] Furthermore, the edges at both ends of the inner sleeve are arc surface structures.

[0008] Furthermore, there are six support plates in total, and the support plates are arranged around the axial center of the inner sleeve.

[0009] Furthermore, the length of the lower bottom of the support plate is shorter than the length of the outer bushing.

[0010] Through the above arrangement, the utility model has the following advantages:

[0011] (1) Plastic is light and can significantly reduce weight;

[0012] (2) The injection molding process is simple and the production efficiency is high;

[0013] (3) Plastics are cheap, reducing costs by more than 60% compared to traditional metal linings;

[0014] (4) Adding ice-breaking structure, which cannot be achieved with traditional metal lining;

[0015] (5) By optimizing and reducing weight and strengthening the structure, it is more in line with energy conservation and emission reduction requirements, and the production process is environmentally friendly.

[0016] In summary, the utility model can achieve the ice-breaking function by re-optimizing the design and injecting a new structure while meeting the strength requirements, thereby reducing the cost and weight. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is now further described with reference to the accompanying drawings.

[0021] like Figure 1-3 As shown, a new type of blow molded pipe orifice lining includes an outer bushing 1 and an inner bushing 2 supported in the outer bushing 1, and the outer edge of the plug-in end of the outer bushing 1 is provided with an annular inclined surface structure 4, and the edges at both ends of the inner bushing 2 are arc surface structures. The length of the inner bushing 2 is smaller than the outer bushing 1, and the outer side wall of the inner bushing 2 is provided with six support plates 3 arranged around the inner bushing 2, and the support plates 3 are arranged around the axial center of the inner bushing 2, so that the inner bushing 2 is supported by the support plates 3 in the outer bushing 1 to form an ice-breaking structure.

[0022] Specifically: each support plate 3 is a right-angled trapezoidal structure, and the lower base of the right-angled trapezoidal structure is fixedly connected to the inner wall of the outer bushing 1, and the upper base of the right-angled trapezoidal structure is fixedly connected to the outer wall of the inner bushing 2. The outer bushing 1, the inner bushing 2 and the support plate 3 are integrally formed by injection molding or 3D printing.

[0023] Working principle of this utility model:

[0024] The utility model is preferably formed by injection molding equipment, and the injection molded liner is assembled to the blow molding pipe mouth through assembly tooling. Compared with the traditional metal liner, the utility model has an ice-breaking structure in the plastic liner through re-optimization design to prevent condensed water from freezing in the intake pipe in winter and entering the engine, thereby damaging the engine and causing the vehicle to stall instantly, creating a danger.

[0025] The above description is only an illustrative embodiment of the present invention and is not intended to limit the scope of the present invention. Any equivalent changes and modifications made by any person skilled in the art without departing from the concept and principle of the present invention shall fall within the scope of protection of the present invention.
