Description

Technical Field

[0001] This utility model belongs to the technical field of medical rubber product manufacturing equipment, and in particular relates to a medical rubber stopper manufacturing molding and demolding device. Background Technology

[0002] Medical rubber stoppers are the core sealing components of pharmaceutical packaging containers. They are usually made of elastic materials such as butyl rubber that meet pharmaceutical industry standards. Their core function is to ensure that the medicine is in a sterile and sealed state throughout the entire life cycle of storage, transportation and use, while isolating external moisture, oxygen and microbial contamination, and preventing the medicine from deteriorating or becoming ineffective. Medical rubber stopper production refers to the process of manufacturing drug sealing components using elastic materials such as butyl rubber that meet pharmaceutical standards as raw materials, following GMP specifications, and through multiple precision processes. The process typically includes raw material pretreatment, rubber compounding preparation, vulcanization molding, demolding, and deflashing. It also requires cleaning, sterilization, and quality testing. Each step must strictly control cleanliness to ensure that the finished product is free of impurities and leachates, and has good sealing performance and biocompatibility, ultimately producing rubber stopper products that meet drug packaging requirements and ensure drug safety. Currently, there are still significant production challenges in the manufacturing process of medical rubber stoppers. Due to the characteristics of rubber and the close contact between the stopper and the mold cavity during vulcanization, the finished rubber stopper is prone to getting stuck inside the mold. This problem directly makes it difficult for the rubber stopper to be easily removed from the mold, resulting in severe demolding difficulties. This not only disrupts the normal production process and damages the continuity of production, but also requires operators to manually pick up the demolded rubber stoppers one by one and transfer them to designated collection containers. This traditional manual operation method not only greatly increases the labor intensity of the workers, but also significantly reduces the overall production efficiency due to the limited efficiency of manual operation, bringing many inconveniences to the efficient implementation of actual production operations. To address the aforementioned issues, this application proposes a medical rubber stopper manufacturing and demolding device. Utility Model Content

[0003] The purpose of this invention is to provide a medical rubber stopper production molding and demolding device, which solves the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a medical rubber stopper production molding and demolding device, comprising a housing, a mold fixedly connected to the upper surface of the housing, a controller disposed on the left side of the housing, a support frame disposed inside the housing, two sets of electric push rods fixedly connected to the inner bottom wall of the housing, the telescopic end of each electric push rod being fixedly connected to the bottom surface of the support frame, push rods arranged at equal intervals fixedly connected to the upper surface of the support frame, a limiting ring slidably connected to the outer surface of each push rod, the upper surface of each limiting ring being fixedly connected to the bottom surface of the mold, the top end of each push rod penetrating the mold and extending into the interior of the mold, a push plate fixedly connected to the top end of each push rod, the outer surface of each push plate contacting the inner wall of the mold, and multiple sections of electric telescopic rods disposed on the front side of the mold, the telescopic ends of the multiple sections of electric telescopic rods being fixedly connected to a collecting rack.

[0005] Furthermore, a connecting frame is fixedly connected to the bottom surface of the housing, and the upper surface of the connecting frame is provided with fixing holes arranged at equal intervals.

[0006] Furthermore, a connecting plate is fixedly connected to the right side of the controller, and the right side of the connecting plate is fixedly connected to the left side of the housing.

[0008] Furthermore, two connecting blocks are fixedly connected to the front of the opening and closing door, and a handle is fixedly connected to the front of both connecting blocks.

[0009] Furthermore, a transparent panel is snapped onto the front of the opening and closing door, and a reinforcing frame is fixedly connected to the outer surface of the transparent panel. The back of the reinforcing frame is fixedly connected to the front of the opening and closing door.

[0010] Furthermore, a fixing frame is fixedly connected to the front of the mold, and the inner wall of the fixing frame is fixedly connected to the outer surface of the multi-section electric telescopic rod.

[0011] This utility model has the following beneficial effects: This utility model, through the linkage structure of electric push rod, support frame, top rod and push plate, uses electric push rod to provide stable power to drive support frame to drive top rod to rise synchronously, and then drive push plate to push upward smoothly. It can accurately act on the rubber plug stuck in the mold and push it out of the cavity completely. It effectively solves the problem of difficult demolding in traditional production, avoids quality problems such as edge damage and deformation of rubber plug that may be caused by manual forced demolding, and ensures the continuous production process. This utility model sets up multiple electric telescopic rods and a collection rack on the front of the mold. When the rubber plug is pushed out of the mold by the push plate, the multiple electric telescopic rods can drive the collection rack to move precisely to complete the pushing and subsequent collection of the rubber plug. This completely replaces the traditional operation method of manually picking and placing them one by one, greatly reducing the labor intensity of the workers. At the same time, due to the high efficiency of the automated operation, the overall production efficiency is significantly improved. In summary, this device, through its coordinated design of automated demolding and collection, and with the orderly linkage of various components supported by the shell, can not only efficiently solve the problem of rubber stopper jamming, but also achieve fully automated connection of the entire process from demolding to collection. It meets the GMP requirements for cleanliness and efficiency in the production of medical rubber stoppers, and provides strong support for improving production efficiency and product quality stability.

At the same time, the electric push rod 12 is a high-precision electric push rod driven by a servo motor. Its thrust and extension speed can be flexibly adjusted by the controller 4 to adapt to the demolding requirements of rubber plugs of different specifications. The multi-section electric telescopic rod 16 adopts a multi-stage sleeve structure electric telescopic rod, which has the characteristics of long stroke and smooth extension and retraction, and can accurately drive the collection rack 18 to complete the pushing and transfer actions.

[0018] The bottom surface of the housing 1 is fixedly connected to the connecting frame 3, and the upper surface of the connecting frame 3 is provided with fixing holes 7 arranged at equal intervals. In this embodiment, by using the connecting frame 3 in conjunction with the fixing holes 7, the device can be firmly installed in the designated work position in the production workshop with bolts, so as to avoid displacement caused by vibration during the operation of the device and ensure the accuracy of the demolding action.

[0019] The controller 4 is fixedly connected to the right side of the connecting plate 5, and the right side of the connecting plate 5 is fixedly connected to the left side of the housing 1. In this embodiment, the controller 4 and the housing 1 are rigidly connected by the connecting plate 5, which not only ensures that the controller 4 is installed firmly, but also avoids the problem of poor heat dissipation caused by the controller 4 directly touching the housing 1.

[0020] The shell 1 and the mold 2 are hinged together on the front, with the back of the door 6 in contact with the front of the shell 1. In this embodiment, the door 6 can shield and protect the top rod 15, support frame 14 and other components inside the shell 1, while also facilitating the staff to open the door to inspect or maintain the internal components.

[0021] The front of the opening and closing door 6 is fixedly connected to two connecting blocks 10, and the front of the two connecting blocks 10 is fixedly connected to a handle 9. In this embodiment, the handle 9 fixed by the connecting blocks 10 provides a force point for the staff to open and close the door 6, avoiding direct contact with the door body and causing wear, while improving the ease of operation.

[0022] The front of the opening and closing door 6 is fitted with a transparent panel 11, and a reinforcing frame 8 is fixedly connected to the outer surface of the transparent panel 11. The back of the reinforcing frame 8 is fixedly connected to the front of the opening and closing door 6.

[0024] Understandably, this invention utilizes the coordinated action of the electric push rod 12, support frame 14, push rod 15, and push plate 13. The electric push rod 12 outputs stable power, driving the push plate 13 to push upward smoothly, accurately and completely removing the rubber plug stuck in the mold 2. This solves the problem of difficult demolding in traditional methods, avoids product damage caused by manual operation, and ensures production continuity. At the same time, the multi-section electric telescopic rod 16 on the front of the mold 2 drives the collection frame 18 to automatically receive and transfer the rubber plug after demolding, replacing manual picking, which reduces labor intensity and significantly improves production efficiency.

[0025] One specific application of this embodiment is as follows: In use, firstly, the device is securely installed at a designated workstation in the production workshop using bolts through the connecting frame 3 and fixing holes 7 to ensure that the equipment will not shift due to vibration during operation. Then, the controller 4 presets the action parameters of the electric push rod 12 and the multi-section electric telescopic rod 16, including the pushing speed and stroke of the electric push rod 12, as well as the pushing position and transfer timing of the multi-section electric telescopic rod 16 driving the collection rack 18. After the medical rubber stopper is vulcanized and molded in the mold 2, the controller 4 starts the demolding process, the electric push rod 12 extends, and the drive support frame 14 drives the push rod 15 synchronously. As the device rises, the push rod 15 remains stable under the guidance of the limit ring 17, which in turn pushes the push plate 13 upward to completely remove the rubber plug stuck in the mold 2. After the rubber plug is removed from the mold 2, the multi-section electric telescopic rod 16 extends according to preset parameters, driving the collection frame 18 to move below the rubber plug and push it from the mold 2 into the conveying device or collection container of the subsequent process. If it is necessary to repair the push rod 15, support frame 14 and other components inside the housing 1, the operator can hold the handle 9 and drive the opening and closing door 6 to rotate around the hinge point through the connecting block 10 to open it. After the repair is completed, the opening and closing door 6 can be closed to restore the operation of the equipment.
