Description

Technical Field

[0001] The utility model relates to a fixing structure, in particular to a glassware blowing machine. Background Art

[0002] The molding of glassware is the process of transforming molten glass into products with fixed geometric shapes. In this process, the glass needs to be heated to a molten state first, then the glass liquid is quantitatively transported to the mold, and then the molten glass is blown into shape by a blow molding machine. During the glassware blowing process, there is a certain amount of glass surface reheating time, which plays an important role in the uniform distribution of glass in the product and the surface quality of the product.

[0003] In the existing blow molding machine, due to the residual heat of the previous molding cycle, the surface temperature of the molding mold of the blow molding machine varies during each processing, resulting in differences in the surface quality of the entire glass product, affecting the quality of shipment. When the existing blow molding machine is blowing the glass liquid during the processing, a small amount of glass liquid will overflow from the nozzle, and the overflowed part will stick to the blow molding head, affecting the mechanical properties and processing stability.

DETAILED DESCRIPTION

[0020] The utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0021] like Figure 1-2 As shown together, this embodiment is about a glassware blowing machine, including a blowing mold 1 with an upper end opening and a blowing cavity formed inside. A blowing head 6 and an air inlet head 13 clamped on the blowing head 6 are arranged in the gap directly above the blowing mold 1. In order to avoid the problem that the blowing head of a traditional blowing machine is easily sticky to the glass liquid, a gap is set between the blowing head 6 and the blowing mold 1 in this embodiment.

[0022] A pipeline channel 5 connected to the blowing cavity is provided in the blow mold 1; the blow head 6 includes a blowing port 10 connected to the air inlet head 13, a lower enclosure 7 is formed on the lower side of the blow head 6, a gap channel 9 is formed between the lower enclosure 7 and the blow mold 1, and an annular space 8 connected to the gap channel 9 is also formed in the lower enclosure 7; the air inlet head 13 includes a bell mouth 14.

[0023] On this basis, if Figure 2 As shown, the blowing mold 1 is implemented in a manner of comprising two half molds that cooperate with each other and are combined to form a glass container 2. The two half molds are formed along the axial parting line of the blowing mold 1, which ensures the structural integrity of the blowing cavity.

[0024] Furthermore, the blowing mold 1 also includes a mold base 3, and the lower part of the mold base 3 is integrally connected with an extension block 4, and the lower end of the blowing cavity is closed by the mold base 3. In order to dissipate heat from the mold base 3, the maximum thickness of the mold base 3 is reduced in this embodiment, and its maximum thickness is less than the thickness of the blowing mold 1. It is needless to say that the shape of the mold base 3 is set to match the shape of the glassware.

[0025] In order to effectively dissipate the heat of the blow mold cavity in the non-process gap, and it can be understood that it is also for the purpose of dissipating the heat of the inner wall of the blow mold 1, a pipeline channel 5 is provided, and the pipeline channel 5 passes through the extension block 4, the mold base 3, and the blow mold 1 from bottom to top. The free end of the pipeline channel 5 is connected to an external air pump. When working, the air pump is driven to blow cooling gas through the pipeline channel 5. Air is usually used in this embodiment. In addition, during the non-cooling time, the pipeline channel 5 is still full of gas, so the glassware will not flow into the pipeline channel 5 during the blow molding process. It should be noted that the use of air pumps is generally mastered by those skilled in the art, and it is also prior art to set any form of control valve between the air pump and the pipeline channel 5; based on the above structure, the cold air that fills the blow mold cavity through the pipeline channel 5 is dissipated through the gap channel 9 after heat exchange.

[0026] The blowing port 10 is located at the center of the blowing head 6. The blowing port 10 is vertically arranged and faces the upper opening of the blowing mold 1. Figure 1 As shown, the lowermost part of the blowing port 10 is shorter than the lower surround 7, that is, the distance between the blowing port 10 and the blowing mold 1 is greater than the distance between the lower surround 7 and the blowing mold 1. Therefore, during the blow molding process, a small amount of overflowed glass liquid will not stick to the blowing port 10 or the blowing head 6, which in turn ensures the mechanical properties and processing stability, and is beneficial to extending the life of the mechanism.

[0027] In order to speed up the dissipation of heat during the blow molding process, the outer circle of the blowing port 10 is formed with a heat channel 11 located inside the blowing head 6 and connected to the outside. Since the density of hot air is small, the hot air will be discharged upward and discharged to the outside through the heat channel 11 during the upward discharge process, thereby speeding up the dissipation of heat.

[0028] An inwardly concave clamping section 12 is formed above the waist of the blowing head 6, and the air inlet head 13 includes a clamping ring claw 15 that is adapted to the clamping section 12 and clamped and connected to each other. Therefore, the connection between the blowing head 6 and the air inlet head 13 is more stable. It can be understood that the bell mouth 14 is connected to an external compressed air source to provide blowing power for blowing.

[0029] It should be noted that the air inlet head 13 of the present embodiment is connected to an existing mobile device at the front end, so when the glass liquid is input into the blowing cavity, the air inlet head 13 and the blowing head 6 will avoid each other, and this is specially explained.

[0030] In this way, the glassware blowing machine disclosed in the utility model innovatively connects the gap between the blowing head 6 and the blowing mold 1 during the blowing molding process, effectively preventing a small amount of overflowed glass liquid from sticking to the blowing head 6, which would cause a decrease in mechanical properties and stability, and is beneficial to extending the life of the mechanism. The present application not only dissipates the heat of the blowing mold 1 during non-process operations through the pipeline channel 5, but can also dissipate the heat generated during the processing in a timely manner, with good overall processing performance and high stability.

[0031] The above implementation modes are not limitations of the present invention, and the present invention is not limited to the above examples. Any changes, modifications, additions or substitutions made by technicians in this technical field within the technical solution of the present invention also fall within the protection scope of the present invention.
