Vacuum forming and foaming combined use process

Abstract

The invention relates to the technical field of blow molding, and discloses a vacuum forming and foaming combined use process. The process is completed by a mold. The mold comprises a mold base, wherein a mold body is arranged on the outer surface of the top of the mold base; a mold cover is arranged on the outer surface of the top of the mold body; a plurality of sets of pressing plates are arranged in the mold body; a plurality of sets of roller shafts are arranged in the pressing plates and located in the mold body; a connecting belt is arranged between every two adjacent roller shafts; a plurality of sets of rotating rods are arranged on the outer sides of the roller shafts and located in the mold body; magnet plates are arranged on the outer surfaces of the two sides of the rotating rods; and motors are arranged on the outer surfaces of the bottoms of the rotating rods and located in the mold base. According to the vacuum forming and foaming combined use process, the best packaging effect is achieved with the least raw material cost, operation is easy and efficient, standardization is easy to make, large-batch copying is achieved, packaging is attractive without losing the effect, and the application range is wide.

Description

technical field [0001] The invention relates to the technical field of blow molding, in particular to a combined use process of blistering and foaming. Background technique [0002] Blister molding, also known as hollow blow molding, is a rapidly developing plastic processing method. The blow molding process began to be used to produce low-density polyethylene vials during World War II. In the late 1950s, with the birth of high-density polyethylene and the development of blow molding machines, blow molding technology has been widely used; the technology of plastic foaming has a long history. In the 1930s, rigid polyurethane foam and polystyrene foam appeared; in the 1940s, there were polyethylene, polyvinyl chloride, epoxy resin, and phenolic foam; in the 1950s, there were expandable polystyrene foam and soft polyurethane Foam. [0003] Existing foaming and blister molding devices have certain disadvantages in use. For complex-looking products with strange shapes, many cu...

Problems solved by technology

[0005] Aiming at the deficiencies of the prior art, the present invention provides a combined use process of blistering and foaming, with the least cost of raw materials to achieve the best packaging effect, simple and efficient operation, and easy to standardize, to achieve mass replication, and at the same time The packaging is beautiful, yet functional, and can be used in a wide range of advantages. It solves the traditional complex appearance products with strange shapes, many curved surfaces, and large differences between protrusions and depressions. Complex, high cost, difficult to lay film before foaming, difficult to operate, and for products with heavy weight, strict protection and fixing requirements, after packaging in blister boxes, it is not easy to pass the test, such as pressure resistance and drop resistance. To achieve satisfactory results, The cost has increased dramatically, heavy products are not easy to fix, and the packaging cost has increased dramatically when complete protection and fixation are achieved.
