Problems solved by technology

Therefore, there is a problem of safety, and at the same time, the device itself that turns water into steam is expensive.
In addition, the water vapor itself contains moisture, which will cause excessive cooling of the glass container during molding and blowing, resulting in problems such as cracks and bursts.
[0006] The above two glass container manufacturing methods all have the problems of low production efficiency and high production cost

no. 1 Embodiment

[0044] The first embodiment is the manufacturing method of using forming molds to produce glass containers, that is, the forming air is to use the cooled compressed air cooled by the cooling device, and to produce glass containers through the continuous or intermittent work of the cooled compressed air Manufacturing method.

[0045] In the following, each main content of the manufacturing method related to the first embodiment will be described separately.

[0046] 1. Glass container

[0047] (1).Shape

[0048] The shape of the glass container is not limited, and it can be a small-mouth glass bottle, a square glass bottle, a cylindrical glass bottle, an irregular-shaped glass bottle, etc. according to the needs of the application.

[0049] (2).Material

[0050] The material of the glass container is not limited, and may be soda lime glass, borosilicate glass, leaded glass, phosphate glass, aluminosilicate glass, and the like.

[0051]The color of the glass container can be...

no. 2 Embodiment

[0096] The second embodiment is as figure 1 As shown, a glass container manufacturing apparatus 50 equipped with a molding die 103 is provided. The manufacturing device 50 is characterized in that it is equipped with a cooling device 70 for cooling compressed air.

[0097] Each main part of the manufacturing apparatus 50 will be described in detail below.

[0098] 1. Forming mold

[0099] In the second embodiment, the molding die shown in Figure 10(a)~(c) should be used.

[0100] (1). Initial mold

[0101] The initial mold is different according to the different shapes of the glass container. In actual use, the inner cavity of the primary mold should also be demoulded.

[0102] In order to prevent the primary mold from sticking to the glass container blank, the primary mold should also be cooled from the outside of the primary mold or from the inside of the primary mold.

[0103] (2). Molding

[0104] Molding is also different according to the different shapes of the gl...

example

[0152] Below by example, the content of the present invention is described in more detail. Of course, the technical scope of the present invention is not limited to the examples. Appropriate changes can be made within the scope of the purpose of the present invention.

Abstract

A method and equipment for blowing glass container without reheating features that a compressed air at 20-50 deg.C, which is cooled by the cooler (heat exchanger, is used for positive-pressure blowing. Its advantages are high productivity and low cost.

Description

technical field [0001] The present invention relates to a manufacturing method and a glass container manufacturing apparatus for producing a glass container using a molding die. Specifically, it is related to a glass container manufacturing method and manufacturing device with high production efficiency and low production cost. Background technique [0002] Glass is widely used because of its stable chemical properties and good transparency. Glass containers are generally produced using forming molds. Specifically, the molten glass is introduced into the forming mold, and compressed air is used to blow and form it to produce glass containers of various desired shapes. It can be seen from this glass container manufacturing method that the function of compressed air is to blow the molten glass to the inner surface of the forming mold, and make the glass contact the mold, so that the heat of the molten glass is released through the mold. In addition, compressed air is also u...
