A Preliminary Mould for Exhaust

Abstract

The invention relates to a primary mold which is beneficial to exhaust. The primary mold is composed of two mated male molds and a female mold. Both the male mold and the female mold are provided with a cavity through which the two molds cooperate with each other. A bottle body cavity is formed inside the primary mold, and the surface that the male mold and the female mold fit closely is the seam surface, and it is characterized in that: there are several connected bottle body cavity interior and the seam surface on the seam surface. Exhaust slots for outside air, the exhaust slots are located in the lower half of the joint surface. Compared with the prior art, the present invention arranges exhaust grooves in the lower half of the joint surface, which avoids the phenomenon of vacuum forming in the cavity of the bottle body when the glass frit is unloaded, which leads to material skipping, and improves the production of glass bottles. Quality and production efficiency; and the male mold and the female mold are connected by triangular ribs, so that the air in the bottle body cavity first passes through the exhaust groove and then passes through the gap between adjacent triangular ribs to smoothly discharge the air to the outside world.

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 4 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.
