TECHNICAL FIELD
[0001] The application relates to the technical field of molds, in particular to a glass mold structure. BACKGROUND
[0002] A mold is a tool used in the manufacture of plastic, metal, glass, or wax molds, or patterns used in founding and masonry to shape or finish material into useful or decorative items. In its most general form, a mold is an inverted reproduction of the object to be produced. It is typically crafted from material, such as sand, iron, steel or rubber.
[0003] In order to keep the size and shape of the glass workpiece accurate after the traditional glass mold is pressure cast, the glass workpiece needs to be cooled and solidified naturally in the mold, but the traditional mold cooling is natural cooling of the mold itself. Although the glass workpiece cooled naturally is more in line with the production requirements in size and shape, the time spent on natural cooling is relatively long, and the mold cannot be used continuously during this period. Therefore, in the production of glass workpieces of the same size and shape, multiple identical molds are required, but the production cost of the mold is relatively high, and only one type of workpiece can be produced, resulting in a relatively large cost in the production of glass workpieces, and there are obvious deficiencies. CONTENT OF THE UTILITY MODEL
