Extrusion forming method applied to edge frame of luggage case body

Abstract

The invention provides an extrusion forming method applied to an edge frame of a luggage case body. A metal piece is conveyed to a rolling mechanism to be rolled continuously to form an irregular sectional material through a material supplying part of a rolling forming machine. Plastic in a material bucket is heated and melted through an extruding part of an extrusion molding machine, injected into a main mould head, extruded out with the irregular sectional material in the main mould head, and after shaped through a vacuum setting mould of a forming part, the plastic is cooled and solidified through a cooling tank, so that the exterior of the irregular sectional material finally forms mould plastic bodies with the section shapes and the sizes being the same. A drawing part of the extrusion forming machine is matched with the extrusion speed of the main mould head to draw the irregular sectional material and the mould plastic bodies to form the edge frame continuously and pulls the edge frame to a cutting part, and then the edge frame is cut into the predetermined length through a saw table. The whole structural strength of the edge frame can be increased through matching of the irregular sectional material with the mould plastic bodies, the material cost is reduced, the edge frame is lighter, and accordingly the utility that stable structure is achieved, mass production is facilitated, and cost is reduced is achieved.

Description

technical field [0001] The invention relates to an extrusion molding method applied to the frame of a suitcase body, in particular, a metal sheet can be rolled and formed into a special-shaped material by using a rolling forming machine, and then a molded body can be formed from the outside of the special-shaped material by the extrusion forming machine. The frame is continuously molded, and this type of frame can use special-shaped materials to cooperate with the molded body to increase the overall structural strength, reduce material costs and make it lighter. Background technique [0002] By the way, the rapid development of today's society and the improvement of national income have gradually changed the way people live, coupled with the popularity of transportation and more convenient, whether it is for the needs of work, leisure, travel and play to improve Leisure and entertainment, etc., it has become a very frequent thing to go to and from various places by means of ...

AI Technical Summary

Problems solved by technology

[0006] Therefore, in view of the problems and deficiencies that the above-mentioned existing luggage frame is integrally formed by shell plastic or aluminum frame as a structural support, resulting in damage, insufficient structural strength, or the inability to reduce material cost and weight, the inventor collects relevant The materials have been evaluated and considered by many parties, and the invention of this extrusion molding method applied to the frame of the luggage box was designed by using years of experience in research and development in this industry for continuous trial production and modification.
