Abstract

The invention discloses a hot-pressing mold for producing a liquid vertical bag. The hot-pressing mold is made of a metal material with good heat conductivity, preferably aluminum or aluminum alloy orsteel, the mold is composed of 2-4 identical units, and the whole mold is integrally formed. Each unit is composed of a convex surface and a concave cavity, wherein each concave cavity is formed by two inclined arc side convex surfaces and one bottom edge sealing convex surface in a semi-surrounding mode, and the inclined arc edges consist of three arcs which are mutually externally tangent and connected. Compared with a traditional vertical bag, the vertical bag formed by hot pressing of the hot-pressing mold has the advantages that the compression resistance and the impact resistance are greatly improved.

Description

technical field [0001] The invention belongs to molds, in particular to molds for thermoforming liquid stand-up pouches. Background technique [0002] As people's quality of life continues to improve, more and more daily necessities are processed into liquid forms, such as laundry detergent and hand sanitizer. In order to achieve a beautiful appearance, most of these liquid packaging bags adopt the shape of a stand-up pouch. After filling the product, the stand-up pouch often leaks or bursts at the bottom of the stand-up pouch when it is under heavy pressure or handling impact, causing serious pollution and waste. How to improve the compression and impact resistance of the bottom of the stand-up pouch is a technical problem urgently needed by the stand-up pouch manufacturers. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a liquid stand-up pouch hot-pressing mold, and the liquid stand-up pouch produced by hot-...
