Embodiment Construction

[0019] A kind of integral forming method of plasticized vehicle body of the present invention, as figure 1 As shown, after the vehicle body mold is assembled, the surface of the mold is cleaned, a release agent is applied, and the keel 3 is installed between the outer mold 1 and the inner mold 5 through bolts 6 . Put a certain amount of material into the body mold, close the mold, lock the mold with bolts or clamps, push the mold into the oven of the rotational molding equipment, heat the body mold to the specified temperature in the oven and make the mold along the two The axes perpendicular to each other rotate for a period of time, and the materials in the body mold are evenly coated and melted and adhered to the surface of the mold under the action of gravity and heat to form a car body product. After the heating is completed, the mold is cooled and kept for a period of time. Open the body mold bolts or clamps, and take out the body products.

Abstract

The invention discloses a plasticized car body overall-molding method and belongs to the field of automobile production. The main trend of future car development is weight reduction, while weight reduction of the car body is the main way to reduce overall weight. In order to reduce weight, conventional production processes of stamping, welding, coating and the like for the car body are abandoned, instead, one-step molding of a novel plasticized car body is adopted. In order to guarantee safety of the plasticized car body, a mould for molding a spiral plastic car body is of customized structure, that is, structures like keels, reinforcing ribs and so on are placed in the mould, and by these structures, the strength of the car body can be improved, and safety of the same is ensured. Besides, materials for the spiral plastic car body can be subjected to fiber reinforcement treatment. By the plasticized car body overall-molding method, weight reduction of the car body is realized, the molding period is shortened, production cost is reduced and safety of the car body is guaranteed.

Description

technical field [0001] The invention relates to the technical field of auto parts manufacturing, in particular to a method for manufacturing an auto body by using a rotational molding mold and a process. Background technique [0002] The traditional car body is made of steel plate through stamping, welding and painting three processes, and this kind of car body manufacturing process naturally determines the problems existing in the car body, such as the overall weight of the car body, weld defects and cumbersome and complicated processes etc., so the final performance is that the body production efficiency is low, the manufacturing cycle is long, and the manufacturing cost is high. Contents of the invention [0003] The object of the present invention is to innovatively propose a method for integral rotational molding of a vehicle body in view of the problems of heavy vehicle body mass, weld seam defects, and cumbersome and complicated processes existing in the above-menti...
