Problems solved by technology

For plastic packaging boxes, using existing molds for blister molding has low production efficiency, poor adsorption, slow molding speed, and prone to streaks and uneven thickness on the surface, which not only affects the appearance, but also increases the cost of subsequent auxiliary processing. Difficulty, but also lead to high scrap rate after blister molding and large waste of materials

Abstract

The invention discloses a plastic uptake molding method for a plastic packaging box and a plastic uptake mold. The molding method mainly comprises the steps of material taking, softening, feeding, vacuumizing, cooling and shaping, mold dismounting and cutting molding. The plastic uptake mold is adopted for plastic uptake molding of the plastic packaging box and can effectively eliminate stripes and reduce the situation of uneven thickness; the plastic uptake mold has the advantages that the molding speed is high, shaping is convenient, the molding efficiency can be effectively improved, the production cost is reduced, the plastic uptake mold is beneficial to subsequent auxiliary machining of the plastic packaging box, the product quality of the plastic packaging box can be guaranteed, and meanwhile the hand feeling and smoothness of products are improved; and the the plastic uptake mold has the advantages of being simple in structure, convenient to operate and use and the like.

Description

technical field [0001] The invention relates to the technical field of plastic-absorbing moulds, in particular to a plastic-absorbing molding method for plastic packaging boxes and a plastic-absorbing mold. Background technique [0002] Blister molding is a kind of plastic processing technology. The main principle is to heat and soften the flat plastic sheet, then absorb it on the surface of the mold by vacuum, and form it after cooling in the cavity. Various plastic containers and profiles manufactured by vacuum forming are widely used in the power industry, civil building materials and electronics, toys, tools, medicine, food packaging, lighting, advertising, and decorative lamp industries. [0003] Plastic packaging refers to packaging in plastic, and plastic is made of synthetic or natural polymer resin as the main material. After adding various additives, it has ductility under certain temperature and pressure, and it is a kind of material that can fix its shape after ...
