Description

Technical Field

[0001] This utility model relates to the field of pharmaceutical machinery and equipment technology, and in particular to a soft capsule mold. Background Technology

[0002] Soft capsules, with their unique encapsulation properties, not only effectively mask the unpleasant odor of medications but also greatly improve the ease of swallowing. Coupled with their excellent digestibility and absorption, they firmly hold an important position in the pharmaceutical and health supplement industries. In pharmaceuticals, they are commonly used to encapsulate various active ingredients, precisely controlling dosage and helping drugs achieve optimal efficacy. In the health supplement industry, they are also highly favored by consumers because they can perfectly preserve nutrients. Currently, with the increasing health awareness of people and the booming development of the health industry, the market demand for soft capsules is showing a continuous upward trend. This has prompted relevant manufacturers to constantly explore ways to improve production efficiency and product quality. As a key link in soft capsule production, the quality and production efficiency of molds have become core factors determining the success or failure of the entire production process.

[0003] A search revealed that Chinese publication number CN115609682A discloses a soft capsule production mold, belonging to the field of soft capsule mold technology. The mold includes two cylindrical mold bodies with several cavities on their outer surfaces, the cavities on the two mold bodies corresponding to each other. A ring of cavity edges is provided around each cavity edge, the width of which gradually increases from the starting point to the end of the cutting process. The two mold bodies roll relative to each other, causing the corresponding cavity edges to align, and the contents are simultaneously injected into the soft capsule shell within the cavity.

[0004] The aforementioned patent description states that it "includes two cylindrical mold bodies, with a plurality of mold cavities on the outer surface of the mold bodies, and the mold cavities on the two mold bodies correspond one-to-one; the edges of the mold cavities are provided with mold cavity blades for cutting soft capsule skin, and the width of the mold cavity blades gradually increases from the starting end to the cutting end; the two mold bodies roll relative to each other, and the widths of the mold cavity blades on the corresponding mold cavity edges match." However, the main design schemes of current soft capsule molds include single-plate molds and double-plate molds. Single-plate molds have a simple structure and are easy to process and maintain, but they have low production efficiency and are prone to uneven capsule forming. Double-plate molds improve production efficiency through the cooperation of upper and lower plates, but their structure is complex, require high processing precision, and increase manufacturing costs and maintenance difficulty. In addition, existing molds are mostly made of stainless steel or aluminum alloy, which have good corrosion resistance and strength, but are prone to wear during long-term use, affecting the accuracy of capsule forming. Therefore, a soft capsule mold is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a soft capsule mold, which aims to improve the problems of low production efficiency, low uniformity and low precision of capsule forming in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A soft capsule mold includes a base, with multiple supports fixedly connected inside the base, two of the supports being rotatably connected to a rotating shaft, a processing mechanism being provided outside the rotating shaft, and a cleaning mechanism being provided outside the processing mechanism.

[0008] The processing mechanism includes an upper template, which is fixedly connected to the outside of the rotating shaft. An upper mold is fixedly connected to the front end of the upper template. A bottom template is fixedly connected to the top end of the base. A bottom mold is fixedly connected to the top end of the bottom template. A locking block is fixedly connected to the front end of the upper template. A guide component is provided at the top end of the base. A limiting component is provided at the top end of the base.

[0009] Through the above technical solution: the rotating shaft and the bracket are connected to rotate flexibly, enabling the processing mechanism installed on the outside to open and close the mold, creating conditions for the production and processing of soft capsules. The cleaning mechanism is set outside the processing mechanism, which can clean the mold after processing, ensuring the mold is clean, which is beneficial to subsequent production and improves production efficiency. The upper mold at the front end cooperates with the lower mold on the bottom template to form the cavity for soft capsule molding, ensuring that the soft capsule is molded according to the design specifications, guaranteeing product accuracy and quality. The locking block, guide component and limiting component cooperate with each other and play a key role when the mold is closed. The guide component provides guidance for the rotation of the upper template, and the limiting component works with the locking block to realize automatic mold locking, preventing the mold from opening accidentally during injection, ensuring the stability of the production process and improving the reliability of production.

[0010] As a further description of the above technical solution:

[0011] The limiting component includes a fixing box, the bottom end of which is fixedly connected to the bottom end of the base. A sliding block is slidably connected inside the fixing box. A telescopic column is fixedly connected to the rear end of the sliding block. A spring is sleeved on the outside of the telescopic column. A limiting groove is formed on the outside of the sliding block.

[0012] Through the above technical solution: the fixed box provides installation space for the sliding block and its related components, and is stably connected to the base. When the mold is closed and the locking block slides into the fixed box, the sliding block moves due to the guidance of the inclined surface of the limiting groove, compressing the spring. Then the spring pushes the sliding block to reset, and the locking block is locked by the limiting groove, realizing automatic mold locking. Relying on a simple mechanical principle, the stability of mold closure is enhanced, manual intervention is reduced, production efficiency is improved, and the risk of product quality problems caused by mold loosening is also reduced.

[0013] As a further description of the above technical solution:

[0014] The guide assembly includes a guide post, the guide post being fixedly connected to the top of the base, and a sliding ring being slidably connected to the outside of the guide post.

[0015] The above technical solution involves a guide post vertically fixed to the top of the base, providing a precise straight-line guide path for the rotation of the upper template. A sliding ring is fitted onto the guide post and connected to the upper template. During the rotation of the upper template, the sliding ring slides along the guide post, effectively constraining the movement trajectory of the upper template, making its rotation more stable and precise, and preventing the upper template from shifting or shaking during rotation. This ensures that the upper mold and the bottom mold can be precisely aligned, greatly improving the uniformity and precision of soft capsule molding and ensuring the consistency of product quality.

[0016] As a further description of the above technical solution:

[0017] The upper template has a groove on its outside, and the sliding ring is slidably connected to the inside of the groove.

[0018] The above technical solution, with its groove and sliding ring, further enhances the stability and accuracy of the upper template's rotation. The sliding ring slides within the groove, ensuring that the upper template does not experience displacement deviation due to forces in other directions during its rotation around the axis of rotation. This guarantees the smoothness and accuracy of the upper template's rotation, allowing the mold to maintain a good condition throughout the opening and closing process, which is beneficial for improving the stability and production efficiency of soft capsules.

[0019] As a further description of the above technical solution:

[0020] The outer side of the locking block is slidably connected to the outside of the limiting groove, the rear end of the telescopic column is fixedly connected to the inside of the fixing box, the rear end of the spring is fixedly connected to the inside of the fixing box, and the other end of the spring is fixedly connected to the rear end of the sliding block one.

[0021] Through the above technical solution, the sliding connection between the locking block and the limiting groove realizes the locking function of the mold, and the fixing method of the telescopic column and spring ensures the stability of the mechanism. This automatic locking mechanism is easy to operate and highly reliable, reduces the workload of manual inspection and mold tightening, and improves production efficiency.

[0022] As a further description of the above technical solution:

[0023] The cleaning mechanism includes a fixed block, the rear end of which is rotatably connected to the front end of the guide post, a sliding rod slidably connected to the top end of the fixed block, a fixed post rotatably connected inside the sliding rod, a rubber scraper fixedly connected to the outside of the fixed post, a motor slidably connected inside the fixed block, a gear fixedly connected to the drive end of the motor, the gear being meshed with the fixed block, a connecting rod rotatably connected to the outside of the gear, and a transmission assembly provided at the top end of the fixed block.

[0024] Through the above technical solution: the fixed block and the guide column are rotatably connected, and the position can be automatically adjusted according to the rotation state of the upper mold. The motor drives the gear to rotate, and the meshing of the gear and the fixed block converts the rotational motion of the motor into the linear motion of the sliding rod, which in turn drives the rubber scraper to move. The rubber scraper is used to clean the residual glue and other impurities on the surface of the bottom mold, realizing automated cleaning without manual cleaning, greatly simplifying the mold cleaning process, reducing downtime, improving production efficiency, and effectively keeping the mold clean and extending the service life of the mold.

[0025] As a further description of the above technical solution:

[0026] The top end of the connecting rod is fixedly connected to the inside of the sliding rod, and the outside of the rubber scraper is slidably connected to the inside of the sliding rod;

[0027] Through the above technical solution: the connecting rod transmits the movement of the gear to the sliding rod, so that the sliding rod can slide stably at the top of the fixed block. The sliding connection design between the rubber scraper and the sliding rod allows the angle and position to be flexibly adjusted according to different cleaning needs when cleaning the bottom mold, effectively improving cleaning efficiency and quality, further ensuring the cleanliness of the mold, and providing good conditions for subsequent soft capsule production.

[0028] As a further description of the above technical solution:

[0029] The transmission assembly includes a second sliding block, which is slidably connected to the outside of the fixed block inside. A transmission rod is rotatably connected to the top of the second sliding block, and the transmission rod is rotatably connected to the front end of the sliding ring.

[0030] Through the above technical solution: the sliding block 2 in the transmission component slides within the fixed block and is connected to the sliding ring via the transmission rod. When the sliding ring rotates with the upper template, it drives the transmission rod to rotate, thereby causing the sliding block 2 to slide within the fixed block. Ultimately, the fixed block rotates automatically with the upper template. This transmission method cleverly combines the rotation of the upper template with the position adjustment of the cleaning mechanism, enabling the cleaning mechanism to clean the mold at the appropriate time. This improves the automation and coordination of mold cleaning, further optimizes the production process, and increases production efficiency.

[0031] This utility model has the following beneficial effects:

[0032] 1. In this utility model, when the operator rotates the upper template around the rotating axis, the guide column and sliding ring work together to provide precise guidance for the rotation of the upper template, ensuring that the upper mold and the bottom mold fit precisely to form a standard molding cavity. This effectively improves the uniformity and precision of soft capsule molding, greatly ensuring product quality. After the upper template rotates into place, the locking block slides into the designated position of the fixed box under the guidance of the inclined surface of the limiting groove. The spring pushes the sliding block to limit the position of the locking block, realizing automatic locking of the mold. This automatic locking mechanism avoids accidental opening of the mold during injection molding, reduces collision damage between molds, and thus extends the service life of the mold and reduces maintenance costs. After production is completed, the motor drives the gear to drive the sliding rod and rubber scraper to automatically clean the bottom mold without the need for tedious manual operation. This not only simplifies the mold cleaning and maintenance process, but also greatly reduces downtime. The entire production process is precise, automatic and efficient, which can well adapt to the needs of large-scale production and significantly improve production efficiency.

[0033] 2. In this utility model, during the operation of the soft capsule mold, as the sliding ring slides outside the guide post, the transmission component drives the sliding block two to slide inside the fixed block, thereby enabling the fixed block to automatically rotate outside the guide component according to the rotation of the upper template. When the mold is closed for processing, the fixed block is at the bottom of the base. After processing is completed, the upper template rotates to the maximum opening position, and the fixed block rotates to the top of the base and is placed horizontally. At this time, the motor is started, and the motor drives the gear to rotate. Because the gear meshes with the fixed block, the connecting rod drives the sliding rod to slide at the top of the fixed block, allowing the rubber scraper to move with the sliding rod to scrape the top of the bottom mold. The rubber scraper slides flexibly inside the sliding rod. When moving in different directions, it either rotates and adjusts itself or is limited in angle by the sliding rod, efficiently cleaning the top of the bottom mold, simplifying the mold cleaning process, and reducing downtime.

Detailed Implementation

[0040] 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.

[0041] Reference Figure 1 , Figure 2 and Figure 4 This utility model provides an embodiment of a soft capsule mold, including a base 1. The base 1 serves as the basic support structure for the entire mold and is stably placed on a production equipment platform. Multiple supports 2 are fixedly connected inside the base 1, and two supports 2 are rotatably connected to a rotating shaft 3. These supports 2 are evenly distributed inside the base 1, which strengthens the structural strength of the base 1 and provides mounting support for components such as the rotating shaft 3. A processing mechanism 4 is provided outside the rotating shaft 3. The processing mechanism 4 is responsible for the soft capsule molding process. A cleaning mechanism 5 is provided outside the processing mechanism 4. The cleaning mechanism 5 is used to clean the key parts of the mold after processing to ensure the smooth progress of the next production.

[0042] The processing mechanism 4 includes an upper template 41, which is externally fixedly connected to the outside of the rotating shaft 3. When soft capsules need to be produced, the operator drives the rotating shaft 3 to rotate using external force, thereby causing the upper template 41 connected to it to rotate smoothly around the rotating shaft 3, preparing for the soft capsule molding operation. An upper mold 42 is fixedly connected to the front end of the upper template 41. The upper mold 42 directly participates in the soft capsule molding process, and its shape and size are customized according to the specifications of the soft capsules to be produced, ensuring the accuracy and quality of soft capsule molding. The top of the base 1 is fixedly connected to... The bottom template 43 has a bottom mold 44 fixedly connected to its top. The bottom template 43 provides a stable mounting surface for the bottom mold 44, ensuring that the bottom mold 44 is fixed in position during production and does not shift. The bottom mold 44 and the upper mold 42 cooperate with each other to form a complete soft capsule molding cavity when they are closed. When the glue is injected into it, it can be molded into a soft capsule. The front end of the upper template 41 is fixedly connected to a locking block 45. The locking block 45 plays a key role in the mold closing process and works in conjunction with the limiting component 46 to realize the automatic locking function of the mold.

[0043] A guide assembly 47 is provided at the top of the base 1. The guide assembly 47 includes guide posts 471, which are externally fixedly connected to the top of the base 1. Two guide posts 471 are symmetrically distributed on both sides of the top of the base 1, providing a precise guide path for the rotation of the upper template 41. A sliding ring 472 is slidably connected to the outside of the guide posts 471. A groove is provided on the outside of the upper template 41, and the sliding ring 472 is externally slidably connected to the inside of the groove. When the operator rotates the upper template 41, the sliding ring 472 will move along the guide posts 471. The outer surface of the base 1 slides smoothly along the axial direction of the guide post 471, thereby ensuring the accuracy of the rotation of the upper template 41 and effectively preventing the upper template 41 from shifting or shaking during rotation. This allows the upper mold 42 and the bottom mold 44 to fit precisely, improving the uniformity and precision of soft capsule molding. The top of the base 1 is provided with a limiting component 46, which includes a fixing box 461. The bottom end of the fixing box 461 is fixedly connected to the bottom end of the base 1. The interior of the fixing box 461 provides space for the sliding block 462 and other components to move.

[0044] A sliding block 462 is slidably connected inside the fixed box 461. The sliding block 462 can slide back and forth inside the fixed box 461. A telescopic column 463 is fixedly connected to the rear end of the sliding block 462. The telescopic column 463 can extend and retract as the sliding block 462 moves. A spring 464 is sleeved on the outside of the telescopic column 463. The spring 464 has good elasticity and can store energy when force is applied and release energy after the force is removed. A limiting groove 465 is opened on the outside of the sliding block 462. When the operator rotates the upper template 41 to make the upper mold 42 fit with the bottom mold 44, the locking block 45 will slide into the inside of the fixed box 461. Due to the slope of the limiting groove 465, the locking block 45 can slide smoothly into the fixed box. At a designated position inside 461, the inclined surface design guides the locking block 45 into place. Then, the spring 464 automatically pushes the sliding block 462 forward inside the fixed box 461, thereby restricting the position of the locking block 45. This completes the automatic locking of the upper mold 42 and the lower mold 44, preventing the mold from accidentally opening during the injection molding process and ensuring the stability of the soft capsule molding process. The rear end of the telescopic column 463 is fixedly connected to the inside of the fixed box 461, and the rear end of the spring 464 is fixedly connected to the inside of the fixed box 461. The other end of the spring 464 is fixedly connected to the rear end of the sliding block 462. This connection method ensures that the spring 464 can stably provide thrust to the sliding block 462.

[0045] Specifically, the base 1, as the fundamental load-bearing component of the entire soft capsule mold, has multiple supports 2 evenly and rationally distributed inside. These supports 2 are made of high-strength materials and are firmly connected to the base 1. This not only greatly enhances the overall structural strength of the base 1, enabling it to stably bear various loads during mold operation, but also provides an extremely stable mounting point for the rotating shaft 3. The rotating shaft 3 passes through two supports 2 and is rotatably connected to them. Driven by a power source, it can rotate smoothly. This allows the processing mechanism 4, which is fixedly connected to the outside of the rotating shaft 3, to smoothly open and close around the rotating shaft 3. The upper mold 42 fixed at the front end of the upper template 41 and the bottom mold 43 fixed at the top of the base 1 and the bottom mold 44 on the bottom template 43 are highly matched in terms of dimensional accuracy and structural design. When the mold is closed, the upper mold 42 and the bottom mold 44 fit tightly together to form a precise soft capsule molding cavity. The size and shape of this cavity are strictly customized according to the production specifications of soft capsules, which can effectively ensure the accuracy of soft capsule molding, reduce product size deviation, and improve product yield. The guide post 471 in the guide assembly 47 is vertically and firmly fixed on both sides of the top of the base 1. Its surface is processed with high precision to ensure a smooth surface.

[0046] The sliding ring 472 is tightly fitted around the guide post 471 and precisely matches the groove on the outside of the upper template 41. When the operator rotates the upper template 41, the sliding ring 472 slides smoothly along the axial direction of the guide post 471. With the precise guiding effect of the guide post 471, the upper template 41 is effectively prevented from shifting or shaking during rotation, thus allowing the upper mold 42 and the bottom mold 44 to fit precisely, significantly improving the uniformity of soft capsule molding, ensuring consistent soft capsule wall thickness and neat appearance. The fixing box 461 of the limiting component 46 is firmly connected to the bottom of the base 1, providing a stable installation space for the sliding block 462, telescopic post 463 and spring 464 inside. The sliding block 462 can slide smoothly back and forth inside the fixing box 461, and the limiting groove 465 on its outside has a special inclined surface design. When the upper template 41 is rotated to bring the upper mold 42 into contact with the bottom mold 44, the locking block 45 at the front end of the upper template 41 slides into the fixing box 461. Guided by the inclined surface of the limiting groove 465, it smoothly reaches the designated position inside the fixing box 461. At this time, the compressed spring 464 releases its elastic potential energy, pushing the sliding block 462 forward, causing the limiting groove 465 to lock the locking block 45, forming an automatic locking mechanism. This mechanism effectively prevents the mold from accidentally opening during the injection molding process, ensuring the stability of the soft capsule molding process, reducing product quality problems caused by mold loosening, and thus improving production efficiency and product quality.

[0047] Reference Figures 1 to 3 The cleaning mechanism 5 includes a fixed block 52, the rear end of which is rotatably connected to the front end of the guide post 471, allowing the fixed block 52 to rotate around the front end of the guide post 471. The rotation angle is related to the rotation state of the upper template 41. A sliding rod 53 is slidably connected to the top end of the fixed block 52. The sliding rod 53 can slide along a specific direction at the top end of the fixed block 52, providing guidance for the movement of the rubber scraper 55. A fixed post 54 is rotatably connected inside the sliding rod 53, allowing the rubber scraper 55 to rotate flexibly inside the sliding rod 53. A rubber scraper 55 is fixedly connected to the outside of the fixed post 54. The rubber scraper 55 is made of soft and wear-resistant rubber material, which can effectively scrape off the residual glue and other impurities at the top end of the bottom mold 44 without damaging the surface of the bottom mold 44.

[0048] A motor 58 is slidably connected inside the fixed block 52. The motor 58 serves as a power source, providing driving force for the cleaning mechanism 5. A gear 57 is fixedly connected to the drive end of the motor 58. After the motor 58 starts, it drives the gear 57 to rotate at high speed. The gear 57 is meshed with the fixed block 52. Through this meshing method, the rotation of the motor 58 is converted into a specific linear motion. A connecting rod 56 is rotatably connected to the outside of the gear 57. The connecting rod 56 connects the gear 57 and the sliding rod 53, transmitting the motion of the gear 57 to the sliding rod 53. A transmission assembly 51 is provided at the top of the fixed block 52. The transmission assembly 51 includes a second sliding block 512. The external sliding connection of 512 is inside the fixed block 52. When the sliding ring 472 slides outside the guide post 471, the transmission component 51 will drive the second sliding block 512 to slide inside the fixed block 52, so that the fixed block 52 automatically rotates outside the guide component 47 as the upper template 41 rotates, realizing the automatic adjustment of the position of the cleaning mechanism 5 to adapt to the change of the mold opening and closing state. The top of the second sliding block 512 is rotatably connected to the transmission rod 511. The external rotatable connection of the transmission rod 511 is to the front end of the sliding ring 472. Through this connection method, the movement of the sliding ring 472 is transmitted to the second sliding block 512, thereby realizing the rotation of the fixed block 52.

[0049] The top end of the connecting rod 56 is fixedly connected to the inside of the sliding rod 53. When the motor 58 drives the gear 57 to rotate, the gear 57 meshes with the fixed block 52, causing the connecting rod 56 to drive the sliding rod 53 to slide on the top end of the fixed block 52. This causes the rubber scraper 55 to scrape the top end of the bottom mold 44 as the sliding rod 53 moves. The outside of the rubber scraper 55 is slidably connected to the inside of the sliding rod 53. When the rubber scraper 55 moves to one side of the bottom mold 44, it slides inside the sliding rod 53. When the rubber scraper 55 slides to the other side of the bottom mold 44, the sliding rod 53 restricts the rotation range of the rubber scraper 55. This allows the rubber scraper 55 to scrape the top end of the bottom mold 44, cleaning the top end of the bottom mold 44, effectively removing residual impurities, simplifying the mold cleaning process, reducing downtime, and improving production efficiency.

[0050] Specifically, the rear end of the fixed block 52 of the cleaning mechanism 5 is rotatably connected to the front end of the guide post 471. This connection method allows the fixed block 52 to be flexibly and precisely adjusted according to the rotation state of the upper template 41. When the sliding ring 472 slides outside the guide post 471, the transmission component 51 connected to it starts to work. The second sliding block 512 in the transmission component 51 slides along a specific track inside the fixed block 52. The transmission rod 511 rotatably connected to its top end is connected to the front end of the sliding ring 472. Through this connection method, the movement of the sliding ring 472 is precisely transmitted to the second sliding block 512, thereby driving the fixed block 52 to rotate around the front end of the guide post 471, realizing the automatic adjustment of the position of the cleaning mechanism 5, so that it can always be in the best cleaning position. The sliding rod 53 at the top of the fixed block 52 can slide smoothly along a predetermined direction at the top of the fixed block 52, providing precise guidance for the movement of the rubber scraper 55.

[0051] The rubber scraper 55 is rotatably connected to the sliding rod 53 via the fixed column 54. It is made of a special rubber that is soft and highly wear-resistant. When the fixed block 52 is adjusted to the appropriate position, the motor 58 is started. The drive end of the motor 58 drives the gear 57 to rotate at high speed. Since the gear 57 and the fixed block 52 are meshed, the rotation of the gear 57 is converted into a specific linear motion, which is transmitted to the sliding rod 53 through the connecting rod 56. This causes the sliding rod 53 to drive the rubber scraper 55 to scrape and clean the top of the bottom mold 44. This ensures that the rubber scraper 55 scrapes the top of the bottom mold 44 at an appropriate angle and force, reducing downtime and significantly improving production efficiency. At the same time, it effectively keeps the mold clean, reduces mold wear caused by impurities, and extends the service life of the mold, providing a strong guarantee for the continuous and efficient production of soft capsules.

[0052] Working principle: When the processing personnel need to produce soft capsules, the upper template 41 is rotated outside the rotating shaft 3. When the upper template 41 rotates, the sliding ring 472 slides outside the guide post 471, thereby ensuring the accuracy of the rotation of the upper template 41. Then, the upper mold 42 and the bottom mold 44 are fitted together, and the locking block 45 slides into the interior of the fixing box 461. Due to the slope of the limiting groove 465, the sliding block 462 can slide into the designated position inside the fixing box 461. Then, the spring 464 will automatically push the sliding block 462 to slide inside the fixing box 461, thereby restricting the position of the locking block 45. At this time, the automatic locking of the upper mold 42 and the bottom mold 44 is completed. At this time, the solution can be injected into the mold to complete the production of soft capsules.

[0053] When the sliding ring 472 slides outside the guide post 471, the transmission component 51 drives the sliding block 512 to slide inside the fixed block 52. This causes the fixed block 52 to automatically rotate outside the guide component 47 as the upper template 41 rotates. When the mold is closed for processing, the fixed block 52 is at the bottom of the base 1. After processing, when the upper template 41 rotates to its maximum opening position, the fixed block 52 is at the top of the base 1, placed horizontally. At this time, the motor 58 can be started, driving the gear 57 to rotate. Through the gear 57 and the fixed block... The engagement of block 52 causes the connecting rod 56 to drive the sliding rod 53 to slide at the top of the fixed block 52. This causes the rubber scraper 55 to scrape the top of the bottom mold 44 as the sliding rod 53 moves. When the rubber scraper 55 moves to one side of the bottom mold 44, it slides inside the sliding rod 53. When the rubber scraper 55 slides to the other side of the bottom mold 44, the sliding rod 53 restricts the rotation range of the rubber scraper 55, thus allowing the rubber scraper 55 to scrape the top of the bottom mold 44 and clean it.
