Description

Technical Field

[0001] This utility model relates to the field of aromatherapy bottle cap production mold technology, and in particular to a mold core structure for an aromatherapy bottle cap mold. Background Technology

[0002] Aromatherapy bottle cap mold is a specialized mold used for the mass production of aromatherapy product bottle caps. Based on the design specifications and functional requirements of aromatherapy bottle caps, it is processed through a specific manufacturing process. Using injection molding technology, heated and molten plastic raw materials are injected into the mold cavity under high pressure. After cooling and solidification, an aromatherapy bottle cap with the same shape as the cavity is formed. The aromatherapy bottle cap mold consists of two main parts: a moving mold and a fixed mold. The moving mold part drives the bottle cap out when the mold is opened, while the fixed mold part is fixed on the fixed platen of the injection molding machine. When the two are closed, they form a complete bottle cap cavity and are also equipped with a mold core structure.

[0003] The core structure of an aromatherapy bottle cap mold is a crucial part of the mold, consisting of a core and inserts. The core directly shapes the internal form of the bottle cap, determining the dimensions and precision details of the inner surface. Inserts, on the other hand, can be individually designed and manufactured according to the complex features of the bottle cap, facilitating processing and replacement, and improving the mold's versatility and ease of maintenance. The two work closely together, undergoing precise processing and assembly to ensure that the molten plastic cools and solidifies within the cavity formed during injection molding, thereby obtaining the aromatherapy bottle cap's internal structure that meets design requirements. However, the complex core structure of existing aromatherapy bottle cap molds makes it difficult to demold the bottle cap, increasing the contact area and adhesion, limiting the demolding space, and making it difficult to separate the bottle cap using conventional demolding methods. Workers need to use additional methods, which increases the number of operation steps and time costs. Demolding difficulties affect production efficiency, leading to disrupted production rhythms and reduced capacity. Forced demolding can damage the bottle cap and the core, reducing product quality and yield, increasing maintenance costs and downtime, and affecting production continuity and stability.

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.

[0031] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model provides a mold core structure for an aromatherapy bottle cap mold, including a connecting plate 1. Support columns 3 are fixedly connected to the four corners of the inner wall of the connecting plate 1. A lower mold 4 is slidably connected to the middle of the outer wall of the support columns 3. A support block 5 is fixedly connected to the top of the inner wall of the lower mold 4. Multiple mold core mechanisms 12 are fixedly connected to the middle of the inner wall of the support block 5. Multiple moving rods 6 are fixedly connected to the middle of the inner wall of the connecting plate 1. An upper mold 7 is fixedly connected to the top of the outer wall of the lower mold 4. A pouring port 8 is opened in the middle of the outer wall of the upper mold 7. A fixing block 9 is fixedly connected to the bottom of the outer wall of the upper mold 7. Springs 10 are fixedly connected to the left and right sides of the inner wall of the fixing block 9. Vent holes 11 are opened on the front and rear sides of the inner wall of the connecting plate 1.

A hydraulic push rod 22 is rotatably connected to the rear side of the outer wall of the connecting plate 1. Multiple hydraulic rods 13 are rotatably connected to the output end of the hydraulic push rod 22.

[0032] Specifically, the core structure of the aromatherapy bottle cap mold is based on the connecting plate 1 as the basic frame. The support columns 3 are fixed at the four corners of the inner wall of the connecting plate 1 to support and position key components. The lower mold 4 can move up and down by slidingly connecting the support columns 3. The support block 5 is fixed to the top of the inner wall of the lower mold 4. Multiple core mechanisms 12 are fixed to the middle of the inner wall of the support block 5 to determine the internal forming shape of the bottle cap. Multiple moving rods 6 are also fixed to the middle of the inner wall of the connecting plate 1 to assist the mold movement and positioning. The upper mold 7 is fixed to the top of the outer wall of the lower mold 4 and together with the lower mold 4, they form the cavity. The sprue 8 in the middle of the outer wall of the upper mold 7 is the injection port for plastic raw materials. Springs 10 are fixed to both sides of the inner wall of the fixing block 9 at the bottom of the outer wall of the upper mold 7 for buffering, resetting, and auxiliary positioning during mold opening and closing. Vent holes 11 are provided on the front and rear sides of the inner wall of the connecting plate 1 to discharge gas during the injection molding process. The upper mold 7 and lower mold 4 close under the action of the driving device. The lower mold 4 moves upward along the support column 3, and the springs 10 are compressed to ensure accurate mold closing and the formation of a closed cavity. The mold core mechanism 12 determines the internal shape of the bottle cap, and the upper mold 7 and lower mold 4 define the bottle cap. Externally, plastic raw material is injected into the mold cavity under high pressure through the sprue 8, and gas is discharged through the vent 11 to avoid air holes and uneven surfaces on the bottle cap. After the raw material is injected, pressure is maintained to ensure the dimensional accuracy and surface quality of the bottle cap. When the mold opens, the lower mold 4 moves downward along the support column 3 and separates from the upper mold 7. It may cooperate with the ejection mechanism of the injection molding machine through structures such as the moving rod 6 to eject the molded bottle cap, completing the injection molding process. Spring 2 10 assists in the separation of the upper mold 7 and the lower mold 4, providing elastic force.

[0033] Reference Figure 1 , Figure 2 and Figure 5The buffer mechanism 2 includes a spring 201, which is fixedly connected to the four corners of the bottom of the connecting plate 1. A fixed plate 202 is fixedly connected to the bottom of the outer wall of the spring 201. A buffer pad 203 is fixedly connected to the bottom of the outer wall of the fixed plate 202.

A groove 26 is provided on one side of the inner wall of the pouring port 8. Nuts 17 are threadedly connected to the four corners of the outer wall of the upper mold 7.

[0034] Specifically, the bottom structure of the mold includes a spring 201, a fixed plate 202, a buffer pad 203, a support plate 204, and a base plate 205, which work together to provide cushioning, support, and stability. The spring 201, located at the bottom of the connecting plate 1, absorbs vertical impact forces, reducing the impact of vibration on the mold. The sliding connection between the buffer pad 203 and the support plate 204 further absorbs vibration energy and buffers and fine-tunes small horizontal displacements. The support plate 204 and the base plate 205 evenly distribute force to the ground, ensuring mold stability. The connecting rod 206 not only transmits the mold weight and injection force but also... To provide positioning and maintain the stability of the mold structure, a wear-resistant pad 14 is connected to the bottom of the outer wall of the upper mold 7. A groove 15 is opened on the front side of the outer wall of the wear-resistant pad 14 to facilitate the connection and ensure the wear between the structures. A groove 2 16 is also opened on one side of the inner wall of the pouring gate 8. In order to enhance the stability, functionality and processing efficiency of the structure, and to further strengthen the structural strength and durability of the upper mold 7, nuts 17 are connected to the four corners of its outer wall by threads. These nuts 17 not only provide additional fixing points, but also ensure the stability and reliability of the entire upper mold 7 during use.

[0035] Reference Figure 1 , Figure 2 and Figure 3 Multiple sliding rods 18 are fixedly connected to the left and right sides of the outer wall of the fixing plate 202. Gaskets 19 are fixedly connected to the bottom of the outer wall of the multiple sliding rods 18. Screws 20 are threadedly connected to the four corners at the bottom of the fixing plate 202. Multiple bolts 21 are threadedly connected to the bottom of the outer wall of the connecting rod 206. Limiting posts 23 are fixedly connected to the four corners at the bottom of the wear-resistant pad 14. Fixing rings 24 are fixedly connected to the bottom of the outer wall of the limiting posts 23.

[0036] Specifically, multiple sliding rods 18 are fixed on the left and right sides of the fixed plate 202. The bottom of the sliding rods 18 is connected to the pads 19. The sliding rods 18 can assist in positioning and guiding, and the pads 19 increase the contact area and disperse pressure to prevent excessive local stress. The four corners of the bottom of the fixed plate 202 are connected to other components by screws 20 to achieve stable installation. The bottom of the connecting rod 206 is threaded with multiple bolts 21 for fastening and enhancing structural stability. The four corners of the bottom of the wear-resistant pad 14 are provided with limiting posts 23, and the bottom of the pad is connected to the fixing ring 24. The combination of the limiting posts 23 and the fixing ring 24 can limit the displacement of the components, ensure the accurate relative position of each part of the mold during operation, and ensure the overall structural stability and normal function.

[0037] Working Principle: The core structure of the aromatherapy bottle cap mold is based on the connecting plate 1. Support columns 3 are fixedly connected to the four corners of the inner wall of the connecting plate 1, playing a crucial role in support and positioning. The lower mold 4 slides along the support columns 3 via a sliding connection to the outer wall of the support columns 3. A support block 5 is fixedly connected to the top of the inner wall of the lower mold 4, and multiple core mechanisms 12 are fixedly connected to the inner wall of the support block 5. The core mechanisms 12 determine the internal shape of the aromatherapy bottle cap. Multiple moving rods 6 are also fixedly connected to the inner wall of the connecting plate 1. These moving rods 6 are related to other actions and positioning of the mold, playing an auxiliary role in demolding and other processes. The upper mold 7 is fixedly connected to the top of the outer wall of the lower mold 4. The upper mold 7 and the lower mold 4 together constitute the molding... The cavity of the aromatherapy bottle cap has a sprue 8 in the middle of the outer wall of the upper mold 7, which is the entrance for the plastic raw material to be injected into the mold cavity. A fixing block 9 is fixedly connected to the bottom of the outer wall of the upper mold 7. Springs 10 are fixedly connected to the left and right sides of the inner wall of the fixing block 9. Springs 10 provide a certain buffer, reset and auxiliary positioning during the mold opening and closing process. In addition, vent holes 11 are opened on the front and rear sides of the inner wall of the connecting plate 1 to discharge the gas generated during the injection molding process. When the upper mold 7 and the lower mold 4 begin to close under the action of the driving device, the lower mold 4 moves upward along the support column 3 and gradually approaches the upper mold 7. During this process, springs 10 are compressed to a certain extent, which plays a role in buffering and fine-tuning the centering position, ensuring that the upper mold 7 and the lower mold 4 close accurately to form a... A closed cavity is formed by a core mold mechanism 12, which determines the internal shape of the bottle cap. The upper mold 7 and lower mold 4 together determine the external shape of the bottle cap. Plastic raw material is injected under high pressure into the cavity formed by the upper mold 7, lower mold 4, and core mold mechanism 12 through the sprue 8. During the injection molding process, a large amount of gas is generated due to the rapid injection of plastic raw material under high pressure. This gas is discharged from the mold through the vent holes 11 on the front and rear sides of the inner wall of the connecting plate 1, avoiding defects such as air holes and uneven surfaces caused by gas accumulation in the cavity, thus ensuring the molding quality of the bottle cap. After the raw material is injected into the cavity, a certain pressure needs to be maintained for a period of time to allow the plastic to fully fill all corners of the cavity under pressure, ensuring the dimensional accuracy and surface quality of the bottle cap. The upper mold 7 and lower mold 4 open under the action of the driving device. Upon mold opening, the lower mold 4 moves downward along the support column 3, separating from the upper mold 7. During this process, it may cooperate with the ejection mechanism of the injection molding machine through structures such as the moving rod 6 to eject the molded aromatherapy bottle cap from the mold core mechanism 12 and the lower mold 4, completing the entire injection molding process. During the mold opening process, spring 10 also plays a role in assisting the smooth separation of the upper mold 7 and the lower mold 4, providing a certain elastic force. The simple mold core structure ensures the ease of bottle cap demolding, reduces contact area and adhesion, and the separated structure provides a more flexible demolding space, making the bottle cap demolding method more efficient. Workers do not need to use additional means, which reduces operation steps and time costs, improves production efficiency, optimizes production cycle and capacity efficiency, and the venting and upper and lower separation demolding reduces damage to the bottle cap and mold core.Increase product quality and yield, reduce maintenance costs and downtime, and improve production continuity and stability;

[0038] The structure mainly surrounds the bottom of the mold, serving as a buffer, support, and stabilizer. Spring 201 is connected to the four corners of the bottom of the connecting plate 1, and a fixed plate 202 is connected below it. The bottom of the fixed plate 202 is connected to a buffer pad 203, which is slidably connected to the support plates 204 on the front and rear sides. The two support plates 204 are connected to the bottom plate 205. At the same time, the bottom plate 205 is connected to the bottom of the connecting plate 1 through a connecting rod 206. During the mold operation, especially at the moment of mold closing and opening of the injection molding machine, a large impact force and vibration will be generated. Spring 201, installed at the bottom corners of the connecting plate 1, can effectively buffer the impact force from the top and bottom. When the mold is subjected to vibration or impact, spring 201 undergoes elastic deformation, absorbing some energy, thereby reducing the impact on the overall structure of the mold, preventing the loosening and damage of internal parts of the mold due to excessive vibration, ensuring the precision and stability of the mold, and extending the service life of the mold. The buffer pad 203 below spring 201 further enhances the buffering effect. The shock absorption effect not only absorbs the vibration energy that spring 201 cannot completely offset, but also plays a certain role in buffering and fine-tuning the small displacement of the mold in the horizontal direction. Since the buffer pad 203 is slidably connected to the support plate 204, when the mold is subjected to slight vibration or displacement in the horizontal direction, the buffer pad 203 can slide on the support plate 204, thereby relieving the horizontal impact force and ensuring the relative stability of the overall position of the mold. The support plate 204 and the bottom plate 205 constitute the support structure of the bottom of the mold. The support plate 204 evenly distributes the force transmitted from the buffer pad 203 to the bottom plate 205. The bottom plate 205 is connected to the connecting plate 1 through the connecting rod 206, which transmits the weight of the mold and various forces generated during the injection process to the ground or the worktable of the injection molding machine, ensuring that the mold maintains a stable posture during operation and will not tilt or shake due to uneven force. At the same time, the connecting rod 206 also plays a positioning role, ensuring that the relative position between the connecting plate 1 and the bottom plate 205 is fixed, and maintaining the stability of the entire mold structure.
