Technical Field

[0001] The utility model relates to the field of glass mold blowing processes, and in particular to a glass blowing mold with a rotating structure. Background Art

[0002] For products such as pots, cups, barrels, etc. formed by the glass blowing process, when the body part of the product cannot be rotationally formed around the central axis but the bottom of the product can be rotationally formed around the central axis, or when the body part of the product cannot be rotationally formed around the central axis but the bottom of the product is flat, or when the body part of the product can be rotationally formed around the central axis but the bottom of the product cannot be rotationally formed around the central axis, the general practice in this industry is to directly blow and form in a fixed mold cavity, that is, neither the product nor the mold rotates, and there is no relative movement friction between the product and the mold to ensure the formation of the above products. It should be noted that, for example, when there are patterns, squares, irregular shapes, etc. in a part of the product, this part of the product cannot be rotationally formed around the central axis. For the above products, the market has relatively high requirements for the flatness and appearance requirements of the part of the product that can be rotationally formed around the central axis or the flat part of the product.
