Description

Technical Field

[0001] This utility model relates to the field of blow molding technology, specifically to a conformal cooling water channel for the bottom mold of a carbonated bottle and a blow molding mold. Background Technology

[0002] In existing technologies, to meet the support and strength requirements of the bottom of carbonated bottle, the bottom of the bottle has alternating valleys and ridges. However, the cooling channel design of the current carbonated bottle bottom mold is generally limited by machining constraints and is located within a conical space. This design fails to flexibly follow the contours of the inner forming surface of the bottom mold, resulting in inconsistent distances between the cooling channels and the inner forming surface. Specifically, the cooling channels are closer to the valleys of the inner forming surface and farther from the ridges. This uneven cooling effect directly leads to uneven temperature distribution in the carbonated bottle bottom mold, thus affecting the molding effect of the carbonated bottle. Utility Model Content

Detailed Implementation

[0042] The present invention will be further described in detail below with reference to specific embodiments.

[0043] Example 1

[0044] like Figures 1-11 As shown in the figure, this embodiment provides a conformal cooling channel for the bottom mold of a carbonated bottle. The conformal cooling channel 2 is disposed inside the bottom mold of the carbonated bottle and includes an inlet channel 21, radial channels and an outlet channel 28.

[0045] The radial water channels, located near the inner forming surface 1 of the bottom mold of the carbonated bottle, have at least the following characteristics:

[0046] The first part extends radially along the valley bottom 12 of the inner forming surface 1;

[0047] The second part extends radially along the main peak ridge 131 of the inner forming surface 1;

[0048] The third part, which surrounds the circumferential trend of the side peaks 132 and valley bottoms 12 of the inner forming surface 1, connects the first part and the second part.

[0049] The inlet channel 21 and the outlet channel 28 extend inward from the outer wall of the bottom mold of the carbonate bottle, respectively.

[0050] The inlet channel 21 extends toward the center point 11 of the inner forming surface 1 and is connected to the first and second parts of the radial waterway, respectively, and the outlet channel 28 is connected to the third part of the radial waterway.

[0051] Specifically, the bottom mold of the carbonated bottle has an inner forming surface 1, which includes a central depression 11 and valley bottoms 12 and ridges 13 that are alternately distributed around the central depression 11. The ridges 13 include a main ridge 131 and side ridges 132 located on both sides of the main ridge 131. The side ridges 132 are connected to the valley bottoms 12. The distance between the conformal cooling water channel 2 and the inner forming surface 1 is preferably 2-3 mm.

[0052] The first part includes multiple first branch waterways 22, which extend radially along the bottom mold of the carbonated bottle and follow the trend of multiple valley bottoms 12, and one end of each is connected to the inlet waterway 21; the second part includes multiple second branch waterways 23, which extend radially along the bottom mold of the carbonated bottle and follow the trend of multiple main peak ridges 131, and one end of each is connected to the inlet waterway 21; the third part includes a branch connecting waterway 24, which surrounds the bottom mold of the carbonated bottle and follows the trend of the side peak ridges 132 and valley bottoms 12, and connects the other ends of the multiple first branch waterways 22 and the multiple second branch waterways 23 to each other; the first branch waterways 22 and the second branch waterways 23 are alternately distributed on the outer periphery of the inlet waterway 21, and the outlet waterway 28 is connected to the branch connecting waterway 24. By setting the conformal cooling channels 2 in this way, the valley bottom 12, ridge 13 and side ridge 132 of the molding surface 1 inside the carbonate bottle bottom mold are all distributed with corresponding conformal cooling channels 2. During the molding process, the conformal cooling channels 2 have a uniform cooling effect on the inner molding surface 1, and the temperature distribution of the carbonate bottle bottom mold is uniform, which ensures the molding effect of the carbonate bottle.

[0053] The conformal cooling channel 2 also includes a transition channel, which is away from the inner forming surface 1 and located below the radial channel. The outlet channel is connected to the third part of the radial channel through the transition channel.

[0054] The transition waterway includes: a centralized water outlet channel 26, which surrounds the bottom mold of the carbonated bottle; multiple branch connecting water outlet channels 25, which are connected to the centralized water outlet channel 26 via the multiple branch connecting water outlet channels 25; and a water outlet connecting channel 27, which is connected to the water outlet channel 28 via the centralized water outlet channel 26.

[0055] Multiple branch-connecting water outlet channels 25 are arranged at equal angles along the circumference of the bottom mold of the carbonate bottle. This arrangement ensures that the coolant flowing within the multiple branch-connecting water outlet channels 25 flows rapidly to the centralized water outlet channel 26.

[0056] One end of the branch connecting water outlet 25 is connected to the branch connecting water channel 24 at the position corresponding to the side peak 132. With this design, when the coolant flows from the branch connecting water outlet 25 through the side peak 132, it can flow directly from the branch connecting water channel 24 to the water outlet concentration channel 26. This allows the coolant temperature to rise quickly and flow from the branch connecting water channel 24 to the water outlet concentration channel 26. It also facilitates the flow of new coolant from the inlet channel 21 to the first branch water channel 22, the second branch water channel 23, and the branch connecting water outlet 25, ensuring uniform temperature distribution in the bottom mold of the carbonate bottle and guaranteeing the molding effect of the carbonate bottle.

[0057] The branch connecting waterway 24 corresponds to the foot of the main ridge 131. This arrangement results in a shorter cooling path for the conformal cooling waterway, improving cooling efficiency.

[0058] In some embodiments, the branch connecting waterway 24 corresponds to the foot of the side ridge 132 or the bottom of the valley bottom 12. With this arrangement, the cooling path of the conformal cooling waterway is longer, improving the cooling effect at the valley bottom.

[0059] The sum of the cross-sectional areas of the multiple first branch waterways 22 and the multiple second branch waterways 23 is equal to the cross-sectional area of ​​the inlet waterway 21. This setting facilitates the determination of the cross-sectional areas of the first branch waterways 22 and the multiple second branch waterways 23.

[0060] The first branch waterway 22, the second branch waterway 23, the branch connecting waterway 24, and the branch connecting outlet waterway 25 have the same cross-sectional area. This setting facilitates the determination of the cross-sectional area of ​​the branch connecting waterway 24 and the branch connecting outlet waterway 25.

[0061] The sum of the cross-sectional areas of the multiple branch outlet channels 25 is equal to the cross-sectional area of ​​the centralized outlet channel 26. This setting facilitates the determination of the cross-sectional area of ​​the centralized outlet channel 26.

[0062] The number of water outlet connecting channels 27 can be one or more. When there is only one water outlet connecting channel 27: the cross-sectional area of ​​the water outlet connecting channel 27 is equal to the cross-sectional area of ​​the water outlet channel; when there are multiple water outlet connecting channels 27: the sum of the cross-sectional areas of the multiple water outlet connecting channels 27 is equal to the cross-sectional area of ​​the water outlet channel. By setting the cross-sectional area of ​​the water outlet connecting channel 27 to correspond to the cross-sectional area of ​​the water outlet channel, it is convenient to determine the cross-sectional area of ​​the water outlet connecting channel.

[0063] It should be noted that the cross-sectional areas of the inlet and outlet channels are fixed.
