Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a mold for manufacturing plastic bottle caps for liquor. Background Technology

[0002] With the continuous upgrading of consumption and the increasing demand for standardized packaging in the liquor industry, plastic bottle caps have gradually become the mainstream choice for liquor packaging due to their advantages such as controllable cost, good sealing performance, and diverse shapes. In particular, plastic bottle caps with integrated cylindrical structures have gained further market favor because they can effectively prevent bottle caps from falling apart during transportation and storage, thereby improving packaging integrity and ease of use.

[0003] A mold for producing integrated plastic bottle caps for liquor typically includes a mold core and a mold frame. The mold core consists of a moving mold core, a fixed mold core, and two sets of symmetrically arranged sliding side-pulling cores. The moving mold core and the fixed mold core are symmetrically arranged vertically to form the mold cavity used to generate the outer contour of the product. The two sets of symmetrically arranged sliding side-pulling cores are used to generate the inner contour of the upper and lower diameters of the product. The mold frame is divided into a moving mold frame and a fixed mold frame. The moving mold frame generally includes a moving mold plate that fixes the moving mold core at the top, a moving mold fixing plate that connects to the injection molding machine at the bottom, and an ejector pin device set between the moving mold plate and the moving mold fixing plate to separate the product from the mold.

[0004] Traditional molds for manufacturing plastic bottle caps for baijiu (Chinese liquor) lack auxiliary demolding mechanisms. The bottle caps are prone to demolding difficulties due to insufficient or uneven force, requiring manual intervention, severely impacting production line continuity and significantly reducing efficiency. Furthermore, forced demolding can cause edge damage, deformation, or surface scratches, directly affecting the appearance and sealing of the baijiu bottle caps, thus negatively impacting the overall quality and market competitiveness of the baijiu product. Therefore, a new mold for manufacturing plastic bottle caps for baijiu is proposed to address these issues. Utility Model Content

[0011] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0012] Example 1: A mold for manufacturing integrated plastic bottle caps for liquor, referring to... Figures 1 to 3The system includes an operating platform 1, which serves as the foundational support structure for the entire mold, providing a stable platform for the installation and operation of subsequent mechanisms. Four guide rails 2 are fixedly connected internally to the operating platform 1, and each guide rail 2 is slidably connected to a moving mold pad 3. A pressing mechanism 5 is fixedly connected externally to the moving mold pad 3. The guide rails 2 precisely guide the sliding direction of the moving mold pad 3, preventing it from shifting during movement. A quick-change mechanism 6 is fixedly connected internally to the moving mold pad 3. The moving mold pad 3 can drive the pressing mechanism 5 and the quick-change mechanism 6 to move accordingly, meeting the mold opening and closing requirements. The mold base plate 3 is equipped with a secondary ejection mechanism 4. The secondary ejection mechanism 4 can smoothly eject the molded plastic bottle cap tube from the mold through two ejection actions, avoiding the product sticking to the mold due to insufficient ejection force or stroke in a single ejection. The pressing mechanism 5 can pressurize the raw material when the mold is closed, so that the raw material can fully fill the mold cavity and ensure the molding quality of the plastic bottle cap tube. The quick change mechanism 6 includes multiple locking blocks 62. The other end of the locking block 62 is fixedly connected to the mold core 61. The quick change mechanism 6 can quickly replace the mold core 61 when it is worn or damaged, reducing mold downtime for maintenance and improving production efficiency.

[0013] Specifically, the operating table 1 provides stable support for the overall structure. The four fixed guide rails 2 inside provide precise sliding guidance for the moving mold pad 3. When the mold is working, the moving mold pad 3 slides back and forth along the guide rails 2, driving the external pressing mechanism 5 and the internal quick-change mechanism 6 to move synchronously. When the mold is closed, the pressing mechanism 5 moves closer to the fixed mold side with the moving mold pad 3, pressurizing the raw material to ensure full filling of the mold cavity. After the mold is opened, the moving mold pad 3 drives the relevant mechanisms to reset. At this time, the secondary ejection mechanism 4 is activated. Through two ejection actions, the molded plastic bottle cap tube is smoothly ejected. When the mold core 61 is worn, the quick-change mechanism 6 can quickly complete the replacement while the moving mold pad 3 is stationary, reducing downtime.

[0014] The secondary ejection mechanism 4 includes a pneumatic cylinder 41. A sliding plate 42 is fixedly connected to the drive end of the pneumatic cylinder 41. The pneumatic cylinder 41 serves as the power source for the secondary ejection mechanism 4, providing a stable driving force for the movement of the sliding plate 42. Two rotating top plates 43 are movably connected to the outside of the sliding plate 42. A fixed column 44 is rotatably connected inside each of the two rotating top plates 43. The sliding plate 42 moves under the drive of the pneumatic cylinder 41, triggering the rotation of the rotating top plates 43. When the sliding plate 42 contacts and pushes the rotating top plate 43, the rotating top plate 43 can rotate around the fixed column 44, thereby achieving secondary ejection. The fixed column 44 provides a stable rotation fulcrum for the rotating top plate 43, ensuring that the rotating top plate 43 rotates during the rotation process. The sliding plate 42 is in a stable position and has an ejector assembly 45 slidably connected inside. The ejector assembly 45 is a component that directly contacts the molded product and performs the ejection action. The ejector assembly 45 includes a drive plate 451, and an ejector pin 452 is fixedly connected to the outside of the drive plate 451. The drive plate 451 can drive the ejector pin 452 to move, thereby pushing the product out of the mold through the ejector pin 452. The outside of the drive plate 451 is slidably connected to the inside of the sliding plate 42. This sliding connection method allows the sliding plate 42 to move a certain distance on its own first, and then drive the drive plate 451 to perform an ejection. The ejector pin 452 directly contacts the molded plastic bottle cap integral cylinder and ejects the product from the mold cavity through its own movement.

[0015] Specifically, when the secondary ejection mechanism 4 is working, the pneumatic cylinder 41 drives the sliding plate 42 to move. In the initial stage, the sliding plate 42 moves independently, and the ejection assembly 45 does not move at this time. When the sliding plate 42 moves to contact the rotating top plate 43, it pushes it to rotate around the fixed column 44. The rotating top plate then pushes the driving plate 451, which slides along the inside of the sliding plate 42, causing the ejector pin 452 to extend forward. The ejector pin 452 directly contacts the plastic bottle cap integral cylinder, ejecting the product from the mold cavity and completing the secondary ejection action. The entire process achieves the orderly transmission from power input to final ejection through the linkage between components.

[0016] When demolding is required for the mold of the plastic bottle cap for liquor, the pneumatic cylinder 41 is activated. Under the activation of the pneumatic cylinder 41, the sliding plate 42 is driven to slide to the right and outward of the driving plate 451. Since the internal extension and retraction of the sliding plate 42 is outside the driving plate 451, when the sliding plate 42 slides to the right until it can no longer slide, the sliding plate 42 drives the driving plate 451 to slide to the right, performing the first ejection. This ejection can initially lift the product out of the mold cavity, preparing for the second ejection. When the sliding plate 42 slides to the right and contacts the two rotating top plates 43, it drives the two rotating top plates 43 to rotate to the right outside the two fixed columns 44. When the two rotating top plates 43 rotate to the right, one end of the two rotating top plates 43 pushes the outside of the driving plate 451 to slide to the right inside the two sliding plates 42, performing the second ejection. The second ejection can further completely remove the product from the mold, ensuring thorough demolding.

[0017] Specifically, upon initiation of demolding, the pneumatic cylinder 41 outputs power, driving the sliding plate 42 to slide to the right along the outside of the driving plate 451. Initially, the sliding plate 42 only extends and retracts on its own. After sliding to its limit position, it contacts the driving plate 451, causing it to move synchronously to the right, completing one ejection and initially lifting the product from the mold cavity, paving the way for subsequent demolding. As the sliding plate 42 continues to move to the right, it contacts and pushes the two rotating top plates 43, causing them to rotate to the right around the fixed column 44. During the rotation of the rotating top plates 43, one end applies a pushing force to the driving plate 451, causing the driving plate 451 to slide further to the right inside the sliding plate 42, achieving a second ejection, and finally completely removing the product from the mold.

[0018] Because the mold core 61 is prone to wear and damage, and is a key component in the molding of the plastic bottle cap integral tube, its wear and damage will affect the product molding accuracy. One end of the locking block 62 is movably connected to a rotating plate 63, and a fixing rod 64 is rotatably connected inside the rotating plate 63. When it is necessary to quickly replace the mold core 61, rotate the rotating plate 63. The rotation of the rotating plate 63 can release the fixing of the mold core 61. Then, take out the mold core 61 to be replaced and replace it with a new mold core 61. Then, align the locking block 62 at the bottom of the mold core 61 with the external groove of the moving mold pad 3. The cooperation between the locking block 62 and the groove can ensure the mold core... With precise installation, the mold core 61 is pushed into the groove. The mold core 61 drives the locking block 62 to slide to the left and pushes the rotating plate 63 to rotate outside the fixed rod 64. The fixed rod 64 provides rotational support for the rotating plate 63. A spring 65 is installed on the outside of the rotating plate 63. When the rotating plate 63 rotates, it compresses the spring 65 at the bottom of the rotating plate 63. At this time, the spring 65 stores elastic potential energy. When the locking block 62 slides into the groove inside the rotating plate 63, the spring 65 rebounds. The rebound of the spring 65 can push the rotating plate 63 to reset, thereby fixing the locking block 62 and completing the quick replacement.

[0019] Specifically, the mold core 61 is a key component in the molding of the plastic bottle cap integral tube. When it needs to be replaced after wear, first rotate the rotating plate 63. The rotation releases the fixation of the mold core 61, and the old mold core 61 can be taken out. When replacing the mold core 61, align the bottom locking block 62 with the external groove of the moving mold pad 3 to ensure accurate installation and positioning. Push the mold core 61 to make the locking block 62 slide to the left, which in turn pushes the rotating plate 63 to rotate around the fixed rod 64. During this process, the spring 65 at the bottom of the rotating plate 63 is compressed and stores elastic potential energy. When the locking block 62 slides into the internal groove of the rotating plate 63, the spring 65 releases the elastic potential energy and rebounds, pushing the rotating plate 63 to reset and fixing the locking block 62. This completes the quick replacement of the mold core 61 and ensures the molding accuracy of subsequent products.

[0020] Reference Figure 1 , Figure 4 and Figure 5 These locking blocks 62 can slide flexibly inside the moving mold pad 3, thus providing a basis for the replacement of the mold core 61. The external parts of multiple locking blocks 62 are slidably connected to the inside of the moving mold pad 3. This connection method allows the movement of the locking blocks 62 to drive the rotating plate 63 to rotate, thereby achieving the function of fixing or releasing. The fixing rod 64 provides a stable rotation fulcrum for the rotating plate 63, ensuring that its rotation process is smooth and reliable. The spring 65 can realize the automatic reset of the rotating plate 63 through its own extension and retraction characteristics, thereby completing the locking of the locking blocks 62. The other end of the spring 65 is fixedly connected to the fixing block 66. The fixing block 66 provides a stable fixing base for the spring 65, ensuring that its elastic force can effectively act on the rotating plate 63.

[0021] Specifically, the quick replacement mechanism 6 uses the moving mold pad 3 as its mounting base. Its core mechanism achieves the replacement of the mold core 61 through the coordinated movement of the locking block 62, rotating plate 63, fixing rod 64, spring 65, and fixing block 66. During replacement, an external force pushes the locking block 62 to slide within the moving mold pad 3. The locking block 62 drives the rotating plate 63, which is movably connected to it, to rotate around the fixing rod 64. At this time, the rotating plate 63 stretches or compresses the spring 65 connected to it, and the mechanism releases the lock on the mold core 61. After the replacement is completed, the spring 65 releases its elastic force to reset, pulls the rotating plate 63 to rotate in the opposite direction, and then pushes the locking block 62 back to re-lock the mold core 61, thus completing the fixation.

[0022] The fixed rod 64 is externally fixedly connected to the inside of the moving mold pad 3. This connection method ensures the stability of the fixed rod 64 position and provides reliable support for the rotation of the rotating plate 63. The rotating plate 63 is externally rotatably connected to the inside of the moving mold pad 3, so that the rotating plate 63 can rotate flexibly within the moving mold pad 3 to cooperate with the movement of the locking block 62. The fixed block 66 is externally fixedly connected to the inside of the moving mold pad 3, ensuring that the position of the fixed block 66 is fixed, thereby making the installation and action of the spring 65 more stable. Through the cooperation of the locking block 62, the rotating plate 63, the spring 65 and other structures, the mold core 61 can be quickly disassembled and assembled, facilitating the timely replacement of worn and damaged mold core 61.

[0023] Specifically, the moving mold pad 3 serves as the core mounting base, with the fixing rod 64 and fixing block 66 fixed inside it. The former provides stable support for the rotating plate 63, while the latter ensures that the spring 65 is fixed in its mounting position. The rotating plate 63 can rotate flexibly around the fixing rod 64 within the moving mold pad 3. When the mold core 61 needs to be installed, the locking block 62 is pushed, which will cause the rotating plate 63 to rotate against the elastic force of the spring 65. Once the locking block 62 is in place, the spring 65 returns to its original position, pushing the rotating plate 63 to rotate in the opposite direction and locking the locking block 62, thus fixing the mold core 61. When disassembling, the opposite force is applied to make the rotating plate 63 rotate again, breaking free from the constraint of the locking block 62, so that the mold core 61 can be quickly removed, completing the disassembly and assembly.

[0024] Reference Figures 2 to 4 The molding mechanism 5 includes a sliding guide rail 51, which serves as the basic support structure of the molding mechanism 5, providing a stable installation and movement reference for each component. The sliding guide rail 51 is externally fixedly connected to the outside of the moving mold pad 3, forming a stable whole with the moving mold pad 3, ensuring structural stability during the molding process. Four sliding posts 52 are externally fixedly connected to the sliding guide rail 51, and a moving mold frame 53 is slidably connected to the outside of each of the four sliding posts 52. These four sliding posts 52 provide precise guidance for the movement of the moving mold frame 53, allowing the moving mold frame 53 to slide smoothly along the sliding posts 52, ensuring the accuracy of the molding action. The externally fixed guide rail posts 2... A fixed mold frame 54 is connected, and the fixed mold frame 54 and the moving mold frame 53 cooperate with each other to complete the compression molding of the plastic bottle cap of liquor. The fixed column 44 is externally fixedly connected to the inside of the sliding guide rail 51, providing a reliable rotation fulcrum for the rotating top plate 43, ensuring that the rotating top plate 43 rotates stably during operation. The external sliding plate 42 is externally slidably connected to the inside of the sliding guide rail 51, so that the sliding plate 42 can slide smoothly in the sliding guide rail 51, providing a basis for the ejection action. The external rotating top plate 43 is externally rotatably connected to the inside of the sliding guide rail 51, so that it can rotate under the drive of the sliding plate 42, thereby pushing the drive plate 451 to complete the secondary ejection.

[0025] Specifically, the molding mechanism 5 is based on the sliding guide rail 51, which is fixed with the moving mold pad 3 to form a stable whole, providing support and motion reference for each component. During operation, the moving mold frame 53 slides smoothly along the four sliding columns 52 on the sliding guide rail 51, moving closer to or away from the fixed mold frame 54 fixed on the guide rail column 2. The two work together to complete the molding of the plastic bottle cap for liquor. After molding, the sliding plate 42 slides in the sliding guide rail 51, driving the internal rotating top plate 43 to rotate with the fixed column 44 as the fulcrum. The rotating top plate 43 further pushes the driving plate 451 to realize the secondary ejection action and complete the demolding of the molded part.

[0026] The implementation principle of this application embodiment is as follows: When the mold for manufacturing plastic bottle caps for liquor needs to be demolded, the pneumatic cylinder 41 is activated. Under the activation of the pneumatic cylinder 41, the sliding plate 42 is driven to slide to the right and outward of the driving plate 451. Since the internal extension and retraction of the sliding plate 42 is outside the driving plate 451, when the sliding plate 42 slides to the right until it can no longer slide, the sliding plate 42 drives the driving plate 451 to slide to the right, performing one ejection. When the sliding plate 42 slides to the right and contacts the two rotating top plates 43, it drives the two rotating top plates 43 to rotate to the right outside the two fixed columns 44. When the two rotating top plates 43 rotate to the right, one end of the two rotating top plates 43 pushes the outside of the driving plate 451 to slide to the right inside the two sliding plates 42, performing a second ejection.

[0027] Because the mold core 61 is easily worn and damaged, when it is necessary to quickly replace the mold core 61, rotate the rotating plate 63, then take out the mold core 61 that needs to be replaced, replace it with a new mold core 61, then align the locking block 62 at the bottom of the mold core 61 with the groove outside the moving mold pad 3, and push the mold core 61 into the groove. The mold core 61 drives the locking block 62 to slide to the left and pushes the rotating plate 63 to rotate outside the fixed rod 64. When the rotating plate 63 rotates, it causes the spring 65 at the bottom of the rotating plate 63 to compress. When the locking block 62 slides into the groove inside the rotating plate 63, the spring 65 rebounds, completing the quick replacement.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
