Description

Technical Field

[0001] The invention specifically relates to a production process for special-shaped wine bottles. Background Art

[0002] At present, this special-shaped wine bottle is a product of major innovation in the blow-blow method and press-blow method for special-shaped bottles. It has a delicate appearance, beautiful and elegant, smooth lines, and evenly distributed solid glass on both sides of the bottle body, and smooth lines. In view of the current situation that it is very difficult to achieve such uniform thickness and material flow of solid materials by using only the blow-blow method and press-blow method in the existing domestic wine bottle molding process, a "blow-press-blow" Blow-Press-Blow production process for special-shaped wine bottles is proposed. Summary of the invention

[0003] The purpose of the present invention is to propose a special-shaped wine bottle production process in view of the deficiencies in the prior art, and the special-shaped wine bottle production process can well solve the above-mentioned problems.

[0004] In order to achieve the above requirements, the technical solution adopted by the present invention is: a special-shaped wine bottle production process is proposed, and the special-shaped wine bottle production process includes the following steps:

[0005] When designing the initial mold, the two sides of the initial blank are made into imitations, combined with the temperature distribution of the material in the initial mold, the back-blowing time and blowing frequency, the direction of the material in the initial mold during back-blowing, and the actual distribution of the solid material in the initial mold; the two sides of the initial mold are made into immovable materials in the mold, and the airflow direction is guided and the distribution of the solid material is changed by controlling the shape and size of the initial blank; the operation techniques and time requirements from the initial blank molding to the positive blowing are tested, and the control of time and technique also affects the molding effect; after the above-mentioned fine design of the initial mold and the control of the operation techniques and time, the outer side of the glass bottle body is formed to achieve a solid effect; the punch is used to control the stamping time node to evenly separate the initial blank, and at the same time, the flow direction of the glass liquid is guided to make the glass liquid flow more evenly to achieve a full effect; the punch is heated in advance before the material is discharged and the bottle mouth is insulated to reduce the bottle mouth from bursting.

[0006] The advantages of this special-shaped wine bottle production process are as follows:

[0007] This process includes innovative mold design, material innovation, and breakthroughs in molding technology. The glass 2# glass bottle has extremely high requirements for the process, among which the initial mold cavity design and cavity shape and size are the most critical, and play a decisive role in the molding effect of the glass bottle. This process technology achieves a breakthrough in the blow-blowing and pressure-blowing molding technology by adjusting the molding process and mold cavity size, solves the requirements for the appearance design of special glass bottles, improves the appearance quality of high-end products, and fills the industry problem that the domestic "special-shaped bottle" blow-blowing and pressure-blowing process technology has not yet been realized.

[0014] In order to make the objectives, technical solutions and advantages of the present application more clear, the present application is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0015] In the following description, references to "one embodiment", "an embodiment", "an example", "an example", etc. indicate that the embodiment or example described in this manner may include specific features, structures, characteristics, properties, elements or limitations, but not every embodiment or example necessarily includes the specific features, structures, characteristics, properties, elements or limitations. In addition, repeated use of the phrase "according to one embodiment of the present application" may refer to the same embodiment, but does not necessarily refer to the same embodiment.

[0016] For the sake of simplicity, certain technical features well known to those skilled in the art are omitted in the following description.

[0017] According to one embodiment of the present application, a process for producing special-shaped wine bottles is provided, such as Figure 1-3 Shown, including

[0018] In view of the fact that similar bottles in the field of special-shaped bottles have uneven solid material flow on both sides of the bottle body, the initial mold cavity size design and production process of the glass bottle are improved and upgraded, and the blow-blow method and the pressure-blow method are combined. According to the principle of the pressure-blow method, a punch is developed to improve the gas flow in the bottle and ensure uniform material flow. Through the above process adjustments, the two sides of the glass bottle body are finally made to have uniform material flow and perfect solid effect on both sides.

[0019] In order to achieve the above object, the technical solution provided by the present invention is:

[0020] Glass 2# bottle has a wide body, the solid material on both sides of the bottle is thicker and wider, and the material flow lines need to be smooth. In view of the particularly difficult production process of this wine bottle, the first consideration is the design of the forming mold and the primary mold, especially the design of the primary mold plays a decisive role in the final forming effect. When designing the primary mold, consider making the two sides as imitation as possible, because the solid material on both sides of the glass bottle is thicker and wider. To achieve a perfect forming effect, it is necessary to combine the actual conditions such as the temperature distribution of the material in the primary mold, the back-blowing time and blowing frequency, the direction of the material in the primary mold during back-blowing, and the distribution of the solid material in the primary mold. Considering these factors, let the two sides of the primary mold form immovable materials in the mold, and guide the airflow direction and change the distribution of solid materials by controlling the shape and size of the primary mold cavity.

[0021] With the continuous optimization and improvement of the cavity size and shape of the initial mold, and repeated machine operation tests and demonstrations, the initial mold and the finished mold are perfectly combined. At the same time, the operation techniques and time requirements from the initial blank to the positive blowing are also repeatedly tested. The control of time and technique also affects the molding effect. After the fine design of the initial mold and the control of the operation technique and time, the outer side of the glass bottle body is formed to achieve a solid effect, but the material flow is still not smooth and full.

[0022] The above-mentioned embodiments only represent several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the claims.

[0023] After summarizing and analyzing, the glass bottle is still not full enough. This is closely related to the direction of the gas in the initial mold and the distribution of the feed. The uniformity of the material also has a direct impact on the guidance of the gas. Finally, after discussion by the R&D staff, it was proposed to use the punch to control the stamping time node to evenly separate the initial blank, and at the same time guide the flow of the glass liquid to make the glass liquid flow more evenly to achieve a full effect. At the same time, the punch is heated in advance when the material is fed and the bottle mouth is insulated to reduce the phenomenon of bottle mouth bursting. After countless molding tests, the punch design meets the requirements of new processes and new technologies, and finally the wine bottle meets the perfect molding requirements.
