Problems solved by technology

[0002] The body and chassis of the existing car shell are manufactured separately. At the same time, more than 20 inner and outer covering parts of the car body are also independently processed and formed. Not only the production and assembly process is cumbersome, the production efficiency is low, and the cost is high. The strength is poor, so it needs to be improved

Embodiment Construction

[0012] Taking an ordinary car as an example, according to the method for one-shot molding of an automobile body provided by the present invention, the method comprises the following steps: (1) making a pair of car body molds comprising a vehicle body, a chassis and a body cover; (2) making Pull various cores such as car doors, windows, lamps, etc., and insert all kinds of cores into the corresponding core-pulling holes on the car shell mold; (3) Add powdered plastic to the car shell mold and close the mold; ( 4) Turn the car body mold into the heating chamber and make it rotate and heat continuously along the main shaft and the auxiliary shaft perpendicular to each other. The powdery plastic in the car body mold is gradually and evenly coated under the action of gravity and heat energy. Melt and adhere to the entire surface of the mold cavity; (5) transfer the car shell mold to a water mist cooling chamber for water mist cooling; (6) transfer the car shell mold to an air-filled...

Abstract

The invention discloses a method for shaping an automobile shell in one step, comprising the following steps of; manufacturing one set of automobile shell die comprising an automobile body, a chassis and an automobile body panel; manufacturing various loose cores, and inserting various loose cores into corresponding loose core holes on the automobile shell die; adding powdery plastic into the automobile shell die, and closing the die; putting the automobile shell die into a heating chamber to cause the automobile shell die to be rotated and heated along a main shaft and an auxiliary shaft which are mutually vertical; putting the automobile shell die into a water mist cooling chamber to be subjected to water mist cooling; putting the automobile shell die into an inflation pressurizing chamber to be pressurized and shaped; carrying out air cooling to the automobile shell die in an air cooling chamber; demoulding to obtain an automobile shell product which comprises the automobile body, the chassis and the automobile body panel and is reserved with various accessory mounting holes; each accessory mounting hole of the product is shaped by the shaping die; and each accessory mounting hole is correspondingly cut and trimmed. The method has the advantages of simple manufacture technology, high production effect, low cost, good product performance and the like.

Description

Technical field: [0001] The invention relates to a molding method of a car body, in particular to a method for forming a car body at one time. Background technique: [0002] The body and chassis of the existing car shell are manufactured separately. At the same time, more than 20 inner and outer covering parts of the car body are also independently processed and formed. Not only the production and assembly process is cumbersome, the production efficiency is low, and the cost is high. The strength is poor, so it needs to be improved. Invention content: [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art and provide a method for one-time molding of automobile body, which can not only simplify the body structure and production process, improve the strength and impact resistance of body products, but also improve the production efficiency. efficiency. [0004] In order to realize the foregoing invention object, the p...
