Problems solved by technology

[0002] Glass containers have a wide range of uses, and processing various glass containers requires the use of corresponding molds. Take the necked beer bottles, beverage bottles or other similar bottles that are seen in daily life as examples. During the process, due to the low temperature of the neck glass, it is very easy to cause uneven distribution of the material liquid, which will affect the wall thickness of the bottle neck and make the overall quality of the bottle unable to be guaranteed.

Embodiment 1

[0016] Please refer to the attached drawing, which shows a pair of bottle half-molds 1 opposite to each other with the same shape and structure for making beer bottles, and a bottle mold for forming beer bottles is processed at the center of the inner wall of each bottle half-mold 1 Cavity 11, the bottle mold cavity 11 includes a lower bottle body cavity 111 and an upper bottle neck cavity 112, wherein the height of the bottle neck cavity 112 is 60 mm. On the top of a pair of bottle half-moulds 1 and around the bottle neck cavity 112, a group of heat preservation holes 12 with a diameter of 4 mm and a depth of 60 mm are provided at a distance of 10 mm, and each heat preservation hole 12 is equipped with a hole cover 122. In addition, internal threads 121 are processed at the openings of each heat preservation hole 12, and external threads 1221 are processed on the hole cover 122. Through the cooperation of internal and external threads 121, 1221, the hole cover 122 can be relia...

Embodiment 2

[0019] Figure slightly, only change the spacing between the insulation holes 12 to 12mm, the diameter to 5mm and the depth to 50mm, the height of the bottle neck cavity 112 of the bottle mold cavity 11 to 50mm, and the tenon protrusion 13 to a cylinder or a cylinder. Cylindrical pin, mortise cavity is changed into circular hole, all the other are all the same as the description to embodiment 1.

Embodiment 3

[0021] The figure is omitted, only the spacing between the insulation holes 12 is changed to 13.5mm, the diameter is changed to 5.8mm and the depth is changed to 55mm, the height of the bottleneck cavity 112 of the bottle mold cavity 11 is changed to 55mm, and all the others are the same as those of embodiment 1 describe.

Abstract

The invention provides a mold for producing a glass container and belongs to the technical field of mold. The mold includes a pair of half bottle molds that are opposite to each other, a bottle die cavity is composed of a bottle body cavity and a bottleneck cavity and is formed on the inner wall of each of the half bottle molds. The mold is characterized in that heat-insulating holes are regularly distributed around the bottleneck cavity at the upper part of the half bottle mold, so the temperature around the bottleneck cavity can be improved, which is helpful to lead the materials to distribute evenly during the two blowing processes and can guarantee that the wall thickness of the bottleneck is uniform.

Description

technical field [0001] The invention belongs to the technical field of moulds, in particular to a mold for making glass containers. Background technique [0002] Glass containers have a wide range of uses, and processing various glass containers requires the use of corresponding molds. Take the necked beer bottles, beverage bottles or other similar bottles that are seen in daily life as examples. During the process, due to the low temperature of the neck glass, it is very easy to cause uneven distribution of the feed liquid, thereby affecting the uneven wall thickness of the bottle neck, so that the overall quality of the bottle cannot be guaranteed. Contents of the invention [0003] The task of the present invention is to provide a mold for making glass containers that is conducive to the uniform distribution of the material liquid and thereby ensures that the wall thickness of the neck of the bottle is consistent. [0004] The task of the present invention is accomplis...
