A method of forming a glass article

Abstract

The application discloses a glass product forming method, which comprises the following steps: 1, heating the glass product to soften; 2, placing the glass product obtained in step 1 in a forming mold, discharging the air between the contact surface of the glass product and the forming mold by a vacuum pump, and keeping until the glass product is cooled and shaped. The application has the beneficial effects that: the air between the contact surface of the glass product and the forming mold is discharged by the vacuum pump, so that the surface wall of the glass product can be as close as possible to the forming mold, and thus an ideal shape is obtained; and keeping until the glass product is cooled and shaped can avoid deformation.

Description

Technical Field

[0001] This invention relates to the field of glass products. Background Technology

[0002] Currently, most household cookware is made of stainless steel, which can easily lead to the leaching of heavy metals during prolonged high-temperature heating, posing a health risk. Therefore, all-glass cookware has emerged and become quite popular. However, because glass is prone to deformation during manufacturing, the contact surface between the glass and the heating element is irregular. For example, the bottom of a glass kettle is uneven, and the bottom curvature of the glass inner pot of a rice cooker is irregular. Consequently, all-glass cookware generally has poor contact with the heating element and therefore lower power consumption to prevent overheating.

[0003] Currently, the common solution to the problem of uneven bottoms in glass teapots is to grind the bottom of the molded glass. However, because glass is hard and brittle, it is prone to breakage, resulting in a high defect rate and high processing costs. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a method for forming glass products.

[0005] A method for forming glass products includes the following steps in the glass product manufacturing process: 1. Heat the glassware until it softens; 2. Place the glass product obtained in step one into the forming mold, and use a vacuum pump to remove the air between the contact surface between the glass product and the forming mold, and keep it until the glass product cools and sets.

[0006] The beneficial effects of this invention are:

[0007] By using a vacuum pump to remove the air between the contact surface of the glass product and the forming mold, the surface of the glass product can fit as closely as possible to the forming mold, thus obtaining a more ideal shape; keeping the glass product cool and set can prevent deformation. Attached Figure Description

[0008] Figure 1 This is a schematic diagram of the molding structure of the glass pot according to the present invention.

[0009] In the diagram, 1. glass pot, 2. molding mold, 3. vent, 4. vacuum pump. Detailed Implementation

[0010] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0011] Example 1 An embodiment of the present invention is a glass pot forming process; like Figure 1As shown: The bottom of the glass pot 1 is heated until it softens, and then placed on the molding mold 2. The molding mold has multiple vent holes 3. The air between the contact surface of the glass pot 1 and the molding mold 2 is discharged by a vacuum pump 4. The glass pot 1 is kept until it cools and sets, thus obtaining a glass pot with a relatively flat bottom.
