Travelling case twice plastic molding production method

Abstract

The invention discloses a travelling case twice plastic molding production method. The method includes the following steps that (1) a plastic plate is produced through an extruder and film pressing equipment, and the plastic plate is subjected to plastic molding, so that a shell blank is obtained; (2) the shell blank obtained in the step (1) is put in a second die set of a vacuum forming machine,rubber applying is performed by passing through rubber, then composite artificial leather is added, and a case shell is obtained through plastic molding; (3) the case shell obtained in the step (2) issubjected to edge brushing treatment, and then holes are punched in the case shell; (4) an aluminum alloy section is subjected to frame bending treatment through a case aluminum material frame bending machine, the two ends are removed through punching and cutting, and then an aluminum frame is obtained through riveting; (5) holes are punched in the aluminum frame, subsequently coating is performed, and then accessories are mounted; (6) the aluminum frame provided with the accessories and the hole-punched case shell are assembled; and (7) foot supports, foot wheels and a pulling rod are mounted, a lining fabric is glued, and internal accessories are riveted. A case produced through the method is good in pressure resistance, resistant to high temperature and not prone to deformation, and connection between the composite artificial leather and a case shell structure is firmer and more reliable.

Description

technical field [0001] The invention relates to the technical field of case and bag production, in particular to a production method of secondary blister-molded suitcase. Background technique [0002] Suitcase (suitcase) is a class in bags. It includes a luggage body, a telescopic pull rod and a luggage bottom wheel, and is widely used because of its convenience. Suitcases have a long history. [0003] Suitcases, from wooden boxes and large suitcases for clothing only, to portable suitcases and trolley cases in various shapes, the suitcases in people's hands are constantly evolving. [0004] The current luggage manufacturing and materials are still carried out in the old traditional way. Luggage has insufficient material sources, high material prices, long production time, not pressure-resistant, unsightly, easy to change shape, not temperature-resistant, and the folding point is easy to turn white after extrusion. Moreover, traditional bags are all made by one-time blis...

Problems solved by technology

Luggage has insufficient material sources, high material prices, long production time, not pressure-resistant, not beautiful, easy to change shape, not temperature-resistant, and the folding point is easy to turn white after extrusion

Moreover, traditional luggage is made by one-time blister molding, and the artificial leather is fixed on the case shell by bonding, and the structure is not stable enough.
