Description

Technical Field

[0001] This utility model relates to the field of glass bottle production technology, and in particular to a mold structure for a primary mold and a die for glass bottle production. Background Technology

[0002] The beer bottle manufacturing industry, especially the production of small-mouth blown beer bottles, has seen significant development in recent years. With the continuous growth of market demand for beer, the requirements for both the quantity and quality of beer bottles are also increasing. High-quality beer bottles not only ensure the quality and taste of the beer but also enhance brand image and market competitiveness. Therefore, innovation and improvement in beer bottle manufacturing technology are crucial for the development of the entire industry.

[0003] In traditional small-mouth press-blown beer bottle production, there are several conventional methods to solve the problem of the die cap. Common methods include controlling the drip temperature and shape of the material, such as adjusting the drip temperature range as much as possible and striving to achieve a relatively smooth material shape. At the same time, attention is paid to mold design and optimization, such as precisely designing the mating dimensions and shape of the die cap interface and the primary mold interface, and controlling the die cap temperature within a certain range. In addition, in the production process, a funnel and primary mold are generally used separately. The material drips first fall into the funnel, then through the funnel into the primary mold. The die cap also first mates with the funnel, and then with the primary mold to complete the press-blown molding process.

[0004] However, these existing conventional methods have significant drawbacks. Improper control of drip temperature and material shape can easily lead to brittle marks, making precise control difficult. Inadequate mold design, such as poor fit between the brittle and the primary mold interface or excessively low brittle temperature, can also cause brittle marks. Furthermore, separating the funnel from the primary mold and using a step-by-step brittle assembly method results in drip temperature loss, increasing the pressure blow molding time and further increasing the probability of brittle marks, thus affecting product quality. Utility Model Content

[0005] This application provides a mold structure for a primary mold and a stopper for glass bottle production. By combining the funnel with the primary mold and improving the stopper structure, the effect of reducing material droplet temperature loss and lowering the probability of stopper marks is achieved.

[0006] This application provides a mold structure for a primary mold and a sealing end for glass bottle production, which adopts the following technical solution:

[0007] A mold structure for a primary mold and a stopper for glass bottle production includes a stopper assembly and a primary mold assembly. The stopper assembly forms a mating interface with the primary mold assembly. The stopper assembly includes a connector and a fixing base. The connector is frustoconical in shape. The insertion end of the connector is adapted to the corresponding surface of the primary mold assembly to form a sealed connection. A cavity is provided inside the connector to further reduce heat transfer through the cavity, thereby reducing the temperature loss of the material droplets.

[0008] By adopting the above technical solution, this utility model designs a mold structure for a primary mold and a sealing end for glass bottle production. In use, the sealing end component and the primary mold component work together. The plug of the sealing end component is frustoconical and is sealed to the primary mold component. A cavity is set inside the plug to reduce heat transfer to the plug, thereby reducing the temperature loss of the material droplet. This helps to solve the problem of sealing end marks caused by low material droplet temperature, and improves the appearance quality, strength and service life of the glass bottle.

[0009] Preferably, the fixing base is provided with a groove, the plug is inserted into the groove and can rotate within the groove, and a bolt is provided in the groove, the plug and the fixing base are fixed by the bolt, which facilitates disassembly and maintenance.

[0010] By adopting the above technical solution, the plug is divided into two parts, a connector and a fixing base, which are fixed by bolts. When the plug is damaged, only the connector needs to be replaced. At the same time, the connector can rotate in the groove, which facilitates the replacement operation and further reduces the cost of use.

[0011] Preferably, an annular sealing groove is provided at the interface where the connector and the groove fit together, and an annular sealing ring is provided in the annular sealing groove.

[0012] By adopting the above technical solution, an annular sealing ring is set in the annular sealing groove at the interface between the plug and the groove during use. This enhances the sealing performance inside the end cap assembly, effectively prevents heat loss, reduces the temperature loss of the material droplets, lowers the risk of end cap marks caused by temperature changes, and improves the production quality of glass bottles.

[0013] Preferably, a heat insulation layer is further provided in the annular sealing groove, the heat insulation layer comprising heat insulation material filled in the annular sealing groove.

[0014] By adopting the above technical solution, when using the product, a heat insulation layer filled with heat insulation material is set in the annular sealing groove, which can further reduce the heat loss of the connector and the temperature loss of the droplet, thereby avoiding the formation of a smother mark due to the low temperature of the droplet, and improving the appearance quality, strength and service life of the glass bottle.

[0015] Preferably, both the connector and the initial mold assembly are made of cast iron. The connector has good thermal conductivity, which allows its temperature to be appropriately balanced with that of the initial mold assembly after it is connected.

[0016] By adopting the above technical solution, the connector and the initial mold assembly are made of cast iron. Utilizing the good thermal conductivity of the connector, the temperature of the two can be properly balanced after it is inserted into the initial mold assembly, which helps to reduce the temperature loss of the material droplets. This solves the problem of smudged marks in beer bottle production and improves the product's appearance quality, strength, and service life.

[0017] Preferably, the mounting base can be made of a material with low heat transfer, thereby reducing heat loss from the connector.

[0018] By adopting the above technical solution, the temperature of the dripping material is prevented from dropping due to heat loss from the connector during use. This helps to control the dripping temperature, thereby reducing the formation of bottle cap marks and improving the product's appearance quality, strength, and service life.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," "lower," "bottom," and "top" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0028] This utility model discloses a mold structure for a primary mold and a sealing end for glass bottle production, such as... Figure 1 and Figure 2 As shown, it includes a capping component 1 and a primary mold component 2. The capping component 1 and the primary mold component 2 form a mating interface. The two fit together tightly, which helps to realize the pressure blow molding of the glass bottle and avoids excessive exposure of the material droplets during the transfer process, which would cause the temperature to drop and thus reduce the probability of capping marks.

[0029] Specifically, the plug assembly 1 includes a connector 11 and a fixing base 12. The connector 11 is frustum-shaped, a design that facilitates better fitting with the corresponding surface of the initial mold assembly 2 to form a sealed connection. The structural features of the connector 11 are crucial; it is made of cast iron, which has good thermal conductivity, allowing it to maintain a suitable temperature balance with the initial mold assembly 2 after insertion. In practical applications, besides cast iron, alloy materials with similar thermal conductivity can also be considered for manufacturing the connector 11, such as alloys containing a certain proportion of copper, which can also achieve a similar temperature balancing effect. The connector 11 has a cavity 3, an important structural design feature that further reduces heat transfer within the connector 11, thereby reducing temperature loss from the material droplets. The connection method between the connector 11 and the fixing base 12 is also very important. The fixing base 12 has a groove 4, into which the connector 11 is inserted and can rotate, facilitating the installation and adjustment of the connector 11's position. A bolt 5 is installed within the groove 4, and the connector 11 and the fixing seat 12 are fixed together by the bolt 5. This connection method facilitates disassembly and maintenance. When the end cap is damaged, only the connector 11 needs to be replaced, greatly saving costs. Just like the connection of many detachable parts in everyday machinery, the bolt 5 connection is both secure and easy to operate. In other similar mold structures, clamp connections or other methods can be used to replace the bolt 5 connection, as long as the functions of fixing and easy disassembly are achieved. Through this combination, the connector 11 and the fixing seat 12 ensure the overall stability of the end cap assembly 1, and also allow for flexible adjustment and replacement of parts for different usage conditions.

[0030] The primary mold assembly 2 is also an important component of the mold structure, and it is also made of cast iron. The function of primary mold assembly 2 is to receive the material droplets and work with the end cap assembly 1 to complete the pressure blow molding process. The cast iron material can withstand the pressure and temperature changes during the pressure blow molding process, ensuring the service life of the mold. Of course, in some special cases, if higher requirements are placed on the mold's high-temperature resistance or wear resistance, materials such as cast steel can be used to manufacture the primary mold assembly 2.

[0031] An annular sealing groove 6 is provided at the interface where the connector 11 and the groove 4 fit together, and an annular sealing ring 7 is provided in the annular sealing groove 6. The combination of the annular sealing groove 6 and the annular sealing ring 7 is to further enhance the sealing performance between the connector 11 and the fixing seat 12 and prevent the leakage of air and heat. The annular sealing ring 7 is usually made of rubber, which has good elasticity and sealing performance. However, in some high-temperature environments, rubber may age and deform. In this case, a silicone sealing ring can be considered, as silicone has better high-temperature resistance. A heat insulation layer is also provided inside the annular sealing groove 6, which includes heat insulation material filling the annular sealing groove 6. The function of the heat insulation layer is to reduce the heat transfer from the connector 11 to the fixing seat 12 and further reduce the temperature loss of the material droplets. The heat insulation material can be selected from materials with good heat insulation performance, such as asbestos fiber and glass fiber. In practical applications, multiple heat insulation materials can also be used in combination to improve the heat insulation effect.

[0032] The implementation principle of this embodiment is as follows: by combining the funnel and the initial mold, the material droplets can directly enter the initial mold, avoiding the temperature loss caused by the material droplets falling into the funnel first and then entering the initial mold in the prior art. The end cap assembly 1 adopts a separate design of the connector 11 and the fixing seat 12. On the one hand, when the end cap is damaged, only the connector 11 needs to be replaced, saving costs; on the other hand, it reduces the contact area between the end cap and the initial mold, reducing the temperature loss of the material droplets. The cavity 3, annular sealing groove 6, and heat insulation layer in the connector 11 further reduce heat transfer and reduce the temperature loss of the material droplets. At the same time, the connector 11 and the initial mold are made of cast iron, and the fixing seat 12 is made of a material with low heat transfer, which helps to maintain the temperature balance of the mold, reduce the generation of end cap marks, and improve the production quality and efficiency of beer bottles. Compared with the traditional mold structure, this represents a significant improvement and enhancement.

[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
