Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a glass bottle forming mold. Background Art

[0002] The usual process of glass bottle molding is to transfer the preformed bottle to the molding mold, and then blow it into the final bottle body. Therefore, the shape of the molding mold determines the final shape of the glass bottle, and the structure and performance of the molding mold also affect the quality of the glass bottle. The molding mold is generally composed of two mold bodies. The shape of the combined cavity determines the shape of the glass bottle. The mold body is usually formed in one piece. For glass bottles with flatter shoulders, wider shoulders and higher bodies, the arc of the shoulder position of the cavity is larger, which is easy to accumulate materials. It is difficult to use effective tools during cleaning and maintenance. Long-term use will inevitably affect the quality of the bottle. At the same time, when the above-mentioned types of bottles are molded, the exhaust problem of the shoulder is also more serious than that of long-necked and sloping shoulder bottles. Generally, it can only be exhausted by drilling small holes, or exhausting at the joint when the two mold bodies are assembled. This method can often only exhaust the gas in the small holes or gaps, and it is difficult to completely exhaust all the existing gases. In addition, the small holes or gaps are also easy to be blocked, and the residual gas that is difficult to exhaust will inevitably affect the quality of the final product, such as the easy formation of potholes on the surface and bubbles inside. Utility Model Content

[0003] The purpose of the utility model is to overcome the shortcomings of the above-mentioned prior art and provide a glass bottle forming mold which is convenient for cleaning and maintenance of the mold and for completely exhausting the gas at the bottle shoulder position during molding. The mold is suitable for the molding and manufacturing of glass bottles with flatter and wider shoulders and higher bottles.

[0004] The utility model is realized by the following technical solutions:

[0005] A glass bottle forming mold comprises a bottom mold, two mold bodies that cooperate with each other and an upper mold body, each of the mold bodies is movably connected with an upper mold body, and when the two mold bodies are closed, the two upper mold bodies are also integrated into one and form an avoidance hole that allows the bottleneck to pass through, and the bottom mold, the mold body and the upper mold body together enclose a cavity for glass bottle molding; an exhaust gap is provided at the connection between the upper mold body and the mold body, and an exhaust groove is provided on the mold body, and the exhaust groove is connected with the exhaust gap to form an exhaust channel for exhausting the shoulder when the bottle body is formed.

[0006] A further improved technical solution is that the exhaust groove is arranged at the joint of the two mold bodies, and is formed by the joint of the two mold bodies.

[0007] A further improved technical solution is that a first groove with an upward notch is provided at the top of the cavity on the mold body, and a convex edge matching the first groove is provided at the bottom of the upper mold plate. The upper mold plate is covered on the mold body through the cooperation of the convex edge and the first groove, and is connected to each other by screws.

[0008] A further improved technical solution is that when the upper template is embedded and covered on the first groove, the lower surface of the convex edge of the bottom of the upper template fits against the inner bottom surface of the first groove, and a circle of the exhaust gap is formed between the inner side surface of the first groove and the upper template.

[0009] A further improved technical solution is that an exhaust port is also provided on the upper template, and the exhaust port is connected with the exhaust gap and the exhaust groove to form an exhaust channel for exhausting the shoulder during bottle body molding.

[0010] A further improved technical solution is that an exhaust hole for exhausting the bottom of the bottle during molding is provided at a position on the mold body that matches the bottom mold.

[0011] A further improved technical solution is that the exhaust hole is formed by splicing two of the mold bodies.

[0012] A further improved technical solution is that a second groove is provided at the bottom of the mold body, and the second grooves on the two mold bodies enclose a first slot adapted to the bottom mold, and the bottom mold is connected and matched with the two mold bodies by being embedded in the first slot.

[0013] A further improved technical solution is that the exhaust hole is radially arranged in the second groove relative to the cavity in the mold body and is formed by splicing two mold bodies.

[0014] A further improved technical solution is that on the two opposite sides of the two mold bodies, a second slot is provided on the side of one mold body, and a clip is provided on the side of the other mold body, and the two molds are positioned and connected to each other through the cooperation of the clip and the second slot.

[0015] The utility model decomposes the integrated mold which is usually only split into left and right parts into three parts, namely, upper, middle and lower parts, namely, bottom mold, mold body and upper mold plate. Compared with the integrated mold and the form which is only decomposed into the bottom mold and bottle body film, the utility model is more convenient to clean and repair, and is especially suitable for the molding processing of glass bottles with flatter and wider shoulders. The upper mold plate is movably connected with the mold body by screws, etc., and during the bottle molding processing, it is only necessary to close the left and right parts, and the mold at the bottle body and the bottle shoulder position is automatically combined into one, and there is no need to close the mold at the bottle shoulder separately. During cleaning and maintenance, the upper mold plate and the mold body can be directly disassembled, and the upper mold plate and the mold body can be repaired separately, which is convenient for installation and disassembly, and does not increase the molding process. The structural design of the mold body and the upper mold plate forms a circle of exhaust gap after the upper mold plate is installed on the mold body, and cooperates with the exhaust groove arranged on the mold body to form an exhaust channel which can completely exhaust the gas of the bottle shoulder part, so that the glass bottle shoulder is more fully molded and the molding quality is guaranteed. The exhaust groove, exhaust hole and other parts which are easy to be blocked are arranged at the mold joint of the left and right parts, which is convenient for cleaning and maintenance.
