[0002] In the field of packaging containers, vacuum bottles are widely used due to their good preservation and sealing performance. For vacuum bottles with specific structural requirements, such as products with inverted rib on the inner and outer shapes, the design and manufacture of the mold face many challenges.

[0003] Traditional molds often struggle to accurately control the fit between the inverted rib and the overall bottle body when forming such vacuum bottle middle sections with inverted ribs. In the subsequent use of the product, if the inverted rib does not fit well with the bottle body, when vacuum testing is performed, due to internal pressure changes, it may lead to poor sealing and leakage; in the high drop test, due to the insufficient stability of the structure, the bottle body is easily impacted to cause stress concentration at the inverted rib, which may further cause cracking, seriously affecting the integrity and sealing performance of the product; and in a high-temperature test environment, the thermal expansion and contraction characteristics of the material may exacerbate the fit deviation between the inverted rib and the bottle body, which may also cause leakage or damage to the bottle body.

[0004] In addition, during demolding, the presence of the inverted rib significantly increases the difficulty of demolding. Traditional molds lack effective demolding design, often resulting in uneven demolding of the buckle position, such as flattening of the buckle position, which may damage the inverted rib structure of the product, affecting its function and appearance; or the buckle position is pulled up, causing the product size to deform, failing to meet the precision requirements, resulting in a large number of defective products, reducing production efficiency and increasing production costs.

[0005] To overcome the above-mentioned defects, it is urgent to design a special vacuum bottle middle section mold that can accurately construct the fit structure of the inverted rib and the bottle body during forming, ensure the reliability of the product under various strict tests, and optimize the demolding mechanism to smoothly demold the buckle position with sufficient space, avoiding flattening or pulling up, to improve product quality and production efficiency, and meet the growing market demand.

[0019] Compared with the prior art, the utility model has the following beneficial effects:

[0020] The vacuum bottle mold provided by the application has excellent performance in processing the reverse buckle rib and the bottle body cooperation through the accurately designed parting surface and mold opening sequence, and the forming precision of the reverse buckle rib is guaranteed. Therefore, the vacuum bottle is stable in structure due to the good cooperation between the reverse buckle rib and the bottle body in subsequent tests, and the problems of liquid leakage and cracking can be avoided, ensuring the product integrity and sealing performance. At the same time, the mold effectively solves the demolding problem of the reverse buckle rib, eliminates the situation of flattening or pulling up the product, and makes the produced product have a complete reverse buckle rib structure, which not only improves the appearance quality, but also ensures that the reverse buckle rib can normally play the functions of connection or support in the aspects of assembly and use.

[0021] The mold can ensure smooth demolding of the buckle position, and the situation of flattening or pulling up the product does not occur, greatly reducing the generation of defective products caused by demolding problems.

[0022] The reasonable structure design of the mold and the linkage cooperation between the components make the mold opening and ejection process more smooth and efficient. For example, through the synergistic effect of the elastic glue, the nylon on-off device and the buckle mechanism components, the accuracy of the mold opening sequence and the timeliness of the ejection action are ensured, thereby shortening the forming cycle of each product and producing more qualified products in the same time.

[0023] The mold fully considers the stress condition of each component in the mold opening and ejection process during design, and through reasonable structure and component connection mode, the wear and stress concentration caused by mold opening and ejection action are reduced. For example, the limiting effect of the plug screw on the fourth plate and the fifth plate, and the synchronous movement design between the components of the buckle mechanism, all help to reduce the damage risk of the mold in the long-term use process, prolong the service life of the mold.

[0024] The control components such as the nylon on-off device, the elastic glue and the buckle mechanism used in the mold make the mold opening sequence and the ejection operation be accurately performed according to the design requirements. The operator does not need to perform complex operation and adjustment when using the mold, and only needs to follow the normal injection molding machine operation process to realize stable production, improving the convenience and reliability of the production operation.

Embodiments

[0036] Please refer to Figures 1-5 A vacuum bottle middle section mold comprises an upper mold base 1, a lower mold base one 2 and a lower mold base two 3, which cooperates with each other to form a complete mold structure for forming a product 1001 with a buckle rib;

[0037] A sub-parting surface assembly 4 is composed of a parting surface one 401, a parting surface two 402 and a parting surface three 403;

[0038] A main parting surface 5 is provided with a buckle rib position, wherein the parting surface two 402 and the parting surface one 401 are sequentially opened to form a certain distance and give way to the buckle rib position on the main parting surface 5, so as to ensure that the buckle rib does not appear to be flattened or pulled up when demolding.

[0039] The vacuum bottle middle section mold of the present application is mainly composed of the upper mold base 1, the lower mold base one 2, the lower mold base two 3, the sub-parting surface assembly 4 and the main parting surface 5, and the following is the detailed structure and working principle.

[0040] I. Mold main assembly

[0041] Firstly, the upper mold base 1 is assembled, and the first plate 10, the second plate 20 and the third plate 30 are spliced according to the design requirements to ensure that the connection between the plates is tight and accurate.

[0042] Then, the lower mold base one 2 is assembled, and the fourth plate 40, the fifth plate 50, the sixth plate 60, the seventh plate 70 and the eighth plate 80 are sequentially assembled. In the assembly process, the parting surface two 402 is arranged between the fourth plate 40 and the fifth plate 50, and the position is ensured to be accurate through a suitable fixing mode.

[0043] Then assemble the lower mold base two 3, assemble the No. 9 plate 90, the No. 10 plate 100, the No. 11 plate 110, the No. 12 plate 120 and the No. 13 plate 130.

[0044] Assemble the assembled upper mold base 1, lower mold base one 2 and lower mold base two 3, and make them cooperate with each other to form a complete mold structure for forming a product 1001 with a buckle rib.

[0045] Install the sub-parting surface assembly 4 and the main parting surface 5

[0046] Install the sub-parting surface assembly 4 to ensure the installation position of the parting surface one 401, the parting surface two 402 and the parting surface three 403 is accurate, and configure appropriate strength of elastic glue between the parting surface one 401 and the parting surface two 402, wherein the strength of the elastic glue of the parting surface one 401 is greater than that of the parting surface two 402.

[0047] Set the buckle rib position on the main parting surface 5 and install the nylon opener 7 to control the opening sequence.

[0048] Other component installation

[0049] Install the lower mold insert one 9, the lower mold insert two 901, the lower mold insert three 902, the lower mold ejector pin 903 and the upper mold insert 904 between the upper mold base 1, the lower mold base one 2 and the lower mold base two 3 to ensure that these components cooperate with each other and can smoothly eject the formed product 1001 in the subsequent ejection operation.

[0050] Install the buckle mechanism 6 between the No. 8 plate 80 and the No. 13 plate 130, which is composed of the first buckle piece 601, the second buckle piece 602 and the third buckle piece 603, to ensure that the first buckle piece 601 and the third buckle piece 603 can form synchronous movement to realize the linkage cooperation between the components of the mold.

[0051] Working process of the mold

[0052] When the mold starts to open under the action of the injection molding machine, due to the elastic glue between the parting surface one 401 and the parting surface two 402 mold plates, and the strength of the elastic glue of the parting surface one 401 is greater than that of the parting surface two 402, the parting surface one 401 opens first. With the opening action, the No. 2 plate 20 separates from the No. 3 plate 30 by a small distance, then the parting surface two 402 opens, and the No. 4 plate 40 and the No. 5 plate 50 separate.

[0053] Because the No. 4 plate 40 has the second reset rod 801 connected to the No. 11 plate 110, when the parting surface two 402 opens, the No. 4 plate 40 will drive the No. 9 plate 90, the No. 10 plate 100, the No. 11 plate 110 and the No. 12 plate 120 to move upwards together. In this process, the No. 9 plate 90 and the No. 10 plate 100 are limited by the cooperation of the first reset rod 8.

[0054] Because of the nylon shutter 7 on the main parting surface 5, the parting surface two 402 is opened first under the action of the nylon shutter 7, then the parting surface three 403 is opened under the action of inertia, the runner is separated, and finally the main parting surface 5 is opened. When the parting surface two 402 is opened, the opening distance of the No. 9 plate 901 is 5 mm, which makes room for the buckle rib on the main parting surface 5, avoiding the problem that the product 1001 is adhered to the main parting surface 5 or the buckle rib on the main parting surface 5 pulls the product flat due to improper opening distance.

[0055] Ejection process

[0056] When the injection molding machine starts ejection, the ejector pin is on the No. 10 plate 100, and the No. 9 plate 90, the No. 10 plate 100, and the lower mold ejector 903 are ejected together. At the same time, the buckle mechanism 6 drives the No. 4 plate 40, the No. 11 plate 110, and the No. 12 plate 120 to move upward together. Because the No. 4 plate 40 is limited by the plug screw between the No. 4 plate 40 and the No. 5 plate 50, the third buckle mechanism 603 is separated from the first buckle mechanism 601 during the movement.

[0057] When the No. 11 plate 110 and the No. 12 plate 120 are limited to separate from the No. 9 plate 90 and the No. 10 plate 100, and the buckle mechanism 6 is in a disengaged state, the injection molding machine continues to eject, the lower mold ejector 903 ejects the product, and the product is separated from the lower mold insert one 9, realizing the ejection of the product. Finally, the product is taken away by the mechanical hand, completing a product forming and ejection cycle.

[0058] II. Working principle

[0059] Elastic glue action

[0060] In the early stage of mold opening, the elastic glue between the parting surface one 401 and the parting surface two 402 plays a key role. Because the elastic glue strength of the parting surface one 401 is greater than that of the parting surface two 402, when the mold is subjected to the mold opening force, the parting surface one 401 first overcomes the resistance of the elastic glue to open, which ensures that the initial sequence of mold opening meets the design requirements.

[0061] Nylon shutter 7 action

[0062] The nylon shutter 7 on the main parting surface 5 plays a role in controlling the opening sequence during mold opening. After the parting surface one 401 and the parting surface two 402 are opened, the nylon shutter 7 controls the opening sequence of the main parting surface 5, so that the parting surface two 402 is opened first, then the parting surface three 403, and finally the main parting surface 5 is opened. This sequence ensures that the buckle rib on the main parting surface 5 can be given room at the right time, avoiding the phenomenon of pulling flat or pulling high when the buckle is demolded.

[0063] Buckle mechanism 6 action

[0064] The buckle mechanism 6 is composed of a first buckle member 601, a second buckle member 602 and a third buckle member 603, and realizes linkage cooperation between parts during mold opening and ejection. During mold opening, when the fourth plate 40 moves, the relevant plates such as the ninth plate 90 and the tenth plate 100 can be moved synchronously through the linkage of the buckle mechanism 6, so as to ensure the orderly progress of the whole mold opening process.

[0065] During ejection, the buckle mechanism 6 also plays a key role, which can transmit the ejection action to the relevant parts to realize the smooth ejection of the product.

[0066] Parting surface mold opening and buckle position giving way

[0067] During mold opening, the parting surface two 402 and the parting surface one 401 are opened in turn and form a certain distance, and give way to the buckle rib position on the main parting surface 5. When the opening distance of the ninth plate 901 reaches 5mm, enough giving way space can be provided for the buckle rib position on the main parting surface 5, so that the buckle rib position will not appear flat or high when demolding, which ensures the quality and appearance of the product 1001.

[0068] During work, under the ejection action of the injection molding machine, the ejector rod drives the tenth plate 100 to push the ejector plate, and then drives the lower mold ejector 903 to eject the product. At the same time, through the linkage of the buckle mechanism 6, the relevant lower mold inserts such as the lower mold insert one 9, the lower mold insert two 901 and the lower mold insert three 902 also participate in the ejection process of the product, so as to ensure that the product can be smoothly separated from the mold. (Although the injection molding machine is not shown in the figure, it plays an indispensable role in power supply and operation driving in the whole mold running cycle, and constitutes a complete plastic forming production unit with the vacuum bottle middle section mold).

[0069] Through the above mold structure and working principle, the vacuum bottle middle section mold can accurately construct the cooperation structure of the reverse buckle rib and the bottle body during forming, ensure the reliability of the product under various strict tests, and optimize the demolding mechanism, so as to meet the demand of producing vacuum bottle middle section with reverse buckle rib structure.

[0070] It should be understood by those skilled in the art that the embodiments of the utility model shown in the above description and drawings are only examples and do not limit the utility model. The purpose of the utility model has been completely and effectively realized. The function and structure principle of the utility model have been shown and explained in the embodiments, and the embodiments of the utility model can be deformed or modified without departing from the principle.
