Primary die facilitating exhausting

Abstract

The invention relates to a primary die facilitating exhausting. The primary die comprises a male die and a female die which are matched with each other, a cavity communicated from top to bottom is formed in each of the male die and the female die, the two cavities are matched with each other so as to form a bottle-shaped cavity in the primary die, tight clinging surfaces of the male die and the female die which are matched are seam joining surfaces. The primary die facilitating the exhausting is characterized in that a plurality of exhausting grooves communicated with the air inside and outside the bottle-shaped cavity are formed in the seam joining surfaces, and are located in the lower half parts of the seam joining surfaces. Compared with the prior art, the exhausting grooves are formed in the lower half parts of the seam joining surfaces of the primary die, as a result, the phenomenon that vacuum is created in the bottle-shaped cavity to cause material jumping when a glass material is discharged, is avoided, and further the production quality and production efficiency of glass bottles are improved; moreover, the male die and the female die are connected via triangular ribs, so that the air in the bottle-shaped cavity firstly flows through the exhausting grooves, then flows through gaps between every two adjacent triangular ribs, and finally is smoothly exhausted into the environment.

Description

technical field [0001] The invention relates to glass bottle blank processing accessories, in particular to a preliminary mold which is beneficial to exhaust. Background technique [0002] As we all know, the initial mold is one of the important molds for manufacturing glass bottles, such as figure 1 As shown, the initial mold 1 is formed by the cooperation of the male mold 11 and the female mold 12, and the mold cavity 2 that penetrates up and down is provided in the male mold 11 and the female mold 12, and the two mold cavities 2 cooperate with each other so that the entire initial mold A bottle body cavity is formed inside the mold 1, and the surface that the male mold 11 and the female mold 12 are closely attached to is the seam surface 3. In the specific manufacturing process of the glass bottle, the melted glass frit 4 needs to be Through the cooperation of the initial mold 1, the die 5, the core 6 and the bulkhead (not shown), the glass bottle is initially formed, bu...

[0002] As we all know, the initial mold is one of the important molds for manufacturing glass bottles, such as figure 1 As shown, the initial mold 1 is formed by the cooperation of the male mold 11 and the female mold 12, and the mold cavity 2 that penetrates up and down is provided in the male mold 11 and the female mold 12, and the two mold cavities 2 cooperate with each other so that the entire initial mold A bottle body cavity is formed inside the mold 1, and the surface that the male mold 11 and the female mold 12 are closely attached to is the seam surface 3. In the specific manufacturing process of the glass bottle, the melted glass frit 4 needs to be Through the cooperation of the initial mold 1, the die 5, the core 6 and the bulkhead (not shown), the glass bottle is initially formed, but in the prior art, when the glass frit 4 enters the initial mold 1, due to the glass frit 4 Squeeze the air in the primary mold 1 to form a vacuum inside the primary mold 1, resulting in poor feeding of the glass frit 4, resulting in thin shoulders of the glass bottle, uneven thickness of the bottle body, sticking wires in the bottle, etc., and even causing The phenomenon of glass frit 1 material skipping or partial material seriously affects the quality of glass bottle products, and if the material skipping is serious, the glass frit will jump out of the initial mold, which shows that there is a major safety hazard

[0003] In order to solve the above-mentioned problem that the glass frit rebounds due to the vacuum inside the primary mold caused by the feeding of the glass frit and seriously affects the quality of the glass bottle, the present invention proposes a primary mold that is conducive to exhaust and can avoid glass frit jumping.
