Manufacturing method for rotational molding car roof box and rotational molding car roof box

Abstract

The invention discloses a manufacturing method for a rotational molding car roof box and the rotational molding car roof box. The manufacturing method for the rotational molding car roof box comprisesthe following steps that a rotational molding die is provided; filling and heating are conducted; the car roof box is formed; and a taking and containing port is formed. The rotational molding car roof box comprises a car roof box body formed through rotational molding and at least one car roof box door. Through implementation of the manufacturing method for the rotational molding car roof box and the rotational molding car roof box, the rotational molding car roof box is free of gaps and windward face joint parts, the structure force is high, and water prevention can be ensured; upper coverand lower cover buckle pieces do not need to be used, separation or loose buckling risks are avoided, and car roof box materials and the manufacturing cost are saved; the structural force can be ensured by using light materials, and a single person can easily conduct usage and operation; and the problem that during car driving, due to upper cover and lower cover separation of a car roof box, the driving danger is generated is avoided.

Description

technical field [0001] The invention relates to a method for manufacturing a roof box and a roof box, in particular to a method for manufacturing a roof box by rotational molding and a roof box for rotational molding. Background technique [0002] The demand for top boxes continues to increase significantly as the demand for cars increases. However, the progress and improvement of the roof box used today is only limited to the cool and varied appearance or the decorative change of the shape. It needs the essence of combining the upper and lower covers, and there is still no improvement. [0003] The existing conventional roof boxes are all combined structure with upper and lower covers, and are fixed with multiple fastening parts, there is a need to increase the thickness to ensure structural strength, the upper and lower covers cannot be tightly combined and are easily separated by wind blowing, and The upper and lower covers cannot be tightly combined and cannot be waterp...

Problems solved by technology

However, the progress and improvement of the roof box used today is only limited to the cool and diverse appearance or the decorative change of the shape, which requires the essence of the combination of the upper and lower covers, and still does not have any improvement

[0003] The existing conventional roof boxes are all combined structure with upper and lower covers, and are fixed with multiple fastening parts, there is a need to increase the thickness to ensure structural strength, the upper and lower covers cannot be tightly combined and are easily separated by wind blowing, and Disadvantages such as the upper and lower covers cannot be tightly combined and cannot be waterproofed

[0004] Furthermore, the existing known roof boxes are very heavy and difficult to operate by a single person. Most users or an ordinary woman cannot handle them at all, let alone set up the roof box or operate it.
