Die for manufacturing glassware

Abstract

The invention provides a die for manufacturing glassware, belonging to the technical field of a glass die. The die for manufacturing the glassware comprises a die body with a ware forming cavity, an accessory die with an accessory forming cavity, a punch with a punch cooling cavity and a punch connection base; the accessory die is matched with the die body, and corresponds to the center position of the bottom of the die body; and the punch is fixedly connected with the punch connection base, and is matched with the ware forming cavity of the die body. The die is characterized in that an exhaust mechanism which is communicated with the ware forming cavity and is used for leading gas inside the ware forming cavity to the outside is arranged at the bottom of the punch cooling cavity of the punch and positioned at the center position of the bottom. The die provided by the invention has the advantages in that the quality of the glassware can be effectively prevented from being influenced by generation of bubbles; and the cooling and forming speed can be accelerated, so that not only can the production efficiency be improved, but also the energy conversation can be realized.

Description

technical field [0001] The invention belongs to the technical field of glass moulds, in particular to a mold for making glassware. Background technique [0002] The aforementioned glassware such as various glass pot lids, cup lids, various glass basins with reinforcing ribs, and the like. As known in the industry, the process of making glassware is not limited to the process of making glass containers, such as various wine bottles, glass cups, cosmetic bottles, sauce jars, vases and beverage bottles, etc. wait. In the process of manufacturing such glassware and glass containers, the glass frit must be introduced into the glass mold first, and then blown, pressed or centrifugally formed according to different processes, and the mold should be made as fast as possible during the forming process. Otherwise, the gas trapped in the mold cavity will enter the glassware or glass container, resulting in visible bubbles in the glass product, which will affect the appearance quality...

AI Technical Summary

Problems solved by technology

[0007] above When the mold with the structure shown in Figure 4 is forming a glass pot lid, the thickness of the glass is much thicker than that of the aforementioned glass container, especially the thickness of the part corresponding to the accessory molding cavity 21 of the accessory mold 2 Significantly increased, so the air is easy to stay here and difficult to discharge and enter the glass frit, so that the formed glass pot lid has bubbles that are visible to the human naked eye on the pot lid handle and its surrounding area, and the grade of the glass pot lid Unable to improve, and even produce a large number of defective products

[0008]In order to minimize the defective glass pot lids, glassware manufacturers in the industry usually slow down the molding speed, and slowing down the molding speed not only affects production efficiency , waste of energy, and the aforementioned problems are still not obvious enough to overcome

In particular, none of the patents and patent applications listed above, including CN101941791A, can solve the Defects in the mold with the structure shown in Figure 4
