Primary mold capable of exhausting air

Abstract

The invention relates to a primary mold capable of exhausting air. The primary mold consists of a male mold and a female mold, wherein surfaces, tightly adhered, of the male mold and the female mold which are matched with each other are joint surfaces; each joint surface is protruded out of each plane part; a dividing line is formed between each joint surface and each plane part; each dividing line is arranged along a contour line of the edge of each mold cavity; each joint surface is the surface formed between each dividing line and the contour line of the edge of each mold cavity; a plurality of air exhaust slots for communicating the inner part of a bottle body cavity with external air are formed in the joint surfaces. Compared with the prior art, the primary mold has the advantages that the air exhaust slots are formed in the joint surfaces, the phenomenon such as material skip caused by vacuum formed in material discharging in the bottle body cavity can be avoided, and the production quality can be improved; due to the arrangement of the joint surfaces, the matching area of the joint surfaces in the prior art is reduced and the tolerance is reduced; the joint surfaces are arranged to be higher than the plane parts so as to ensure that the plane parts on the male mold and the female mold cannot be in contact, and a gap can be provided for the air exhaust slots to exhaust air; the male mold is connected with the female mold by virtue of a plurality of triangular ribs so as to well exhaust air.

Description

technical field [0001] The invention relates to glass bottle blank processing accessories, in particular to an exhaustable primary mold. Background technique [0002] As we all know, the initial mold is one of the important molds for manufacturing glass bottles, such as Figure 1-2 As shown, the initial mold 1 is formed by the cooperation of the male mold 11 and the female mold 12. On the plane part 10 of the male mold 11 and the female mold 12, a cavity 2 that penetrates up and down is provided, and the two cavity 2 are connected to each other. Cooperate so that a bottle body cavity is formed inside the entire primary mold 1. When the male mold 11 and the female mold 12 are matched together, the surface that closely fits is the seam surface 3. In the specific production and manufacturing process of the glass bottle, it is necessary to melt the The glass frit 4 of the glass bottle is initially formed through the cooperation of the blank 1, the die 5, the core 6 and the bulkh...

[0002] As we all know, the initial mold is one of the important molds for manufacturing glass bottles, such as Figure 1-2 As shown, the initial mold 1 is formed by the cooperation of the male mold 11 and the female mold 12. On the plane part 10 of the male mold 11 and the female mold 12, a cavity 2 that penetrates up and down is provided, and the two cavity 2 are connected to each other. Cooperate so that a bottle body cavity is formed inside the entire primary mold 1. When the male mold 11 and the female mold 12 are matched together, the surface that closely fits is the seam surface 3. In the specific production and manufacturing process of the glass bottle, it is necessary to melt the The glass frit 4 of the glass bottle is initially formed through the cooperation of the blank 1, the die 5, the core 6 and the bulkhead (not shown), but, in the prior art, when the glass frit 4 enters the blank 1 , because the glass frit 4 squeezes the air in the primary mold 1 to form a vacuum inside the primary mold 1, resulting in poor cutting of the glass frit 4, resulting in thin shoulders of the glass bottle, uneven thickness of the bottle body, sticky wire in the bottle, etc. Problems, even cause glass frit 1 material skipping or partial material, which 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 quality of the glass bottle is seriously affected by the rebound of the glass material caused by the vacuum inside the primary mold caused by the feeding of the glass material, the present invention proposes a primary mold that can be vented and can avoid glass material skipping.
