Description

Technical Field

[0001] This utility model relates to the field of sealing cap molding mold technology, specifically a molding mold for a medical device anti-detachment sealing cap. Background Technology

[0002] Rubber seals are a common type of sealing device used in various industries and mechanical equipment. They effectively solve leakage and sealing problems. Rubber seals are a fundamental and universal component in sealing devices, playing a crucial role in sealing. They are the most widely used type of rubber product in sealing technology because rubber is a highly elastic polymer material with a wide temperature range. Under relatively small stress in different media, it will produce large deformations. This deformation can provide contact pressure, compensate for leakage gaps, and achieve the purpose of sealing.

[0003] The above-mentioned technical conditions also have defects: the existing sealing cap has a core and an undercut. The diameter of the undercut is larger than the diameter of the core during molding. Therefore, during molding, the undercut will get stuck in the mold, and some external force is required to demold the sealing cap, which reduces the working efficiency of the sealing cap mold.

[0004] Based on this, this utility model designs a molding die for a medical device anti-detachment sealing cap to solve the above problems. Utility Model Content

Multiple receiving cavities are opened on the core layer. A molding core is fixedly installed on the core layer and inside the receiving cavity. Multiple top cores are detachably installed on the bottom layer. Multiple molding cavities adapted to the molding cores are opened on the top layer. Multiple through holes adapted to the top cores are opened on the core layer. A core column cavity is opened inside the core layer and above the through holes. An undercut cavity is opened on the core layer and at the bottom of the core column cavity.

[0009] By adopting the above technical solution, the movement of the top and bottom layers can be controlled separately, thereby realizing mold closing and mold opening operations.

[0010] Preferably, the frame is also fixedly connected to a slide rail, and there are two core layers. The two core layers are fixedly connected to each other by a connecting rod. The two sides of the two core layers are slidably connected to the two sides of the slide rail. Two limit seats are fixedly connected to the top of the slide rail on both sides. A drive motor is fixedly connected to the outside of one right limit seat. A lead screw is fixedly connected to the output shaft of the drive motor.

[0018] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0020] Reference Figure 1-4 A molding die for a medical device anti-detachment sealing cap includes a bottom layer 1, a top layer 2, a core layer 3, and a frame 12. Four guide pillars 4 are fixedly connected to the core layer 3. Guide holes adapted to the guide pillars 4 are opened on corresponding sides of the bottom layer 1 and the top layer 2. Multiple receiving cavities 5 are opened on the core layer 3. A molding core 6 is fixedly installed on the core layer 3 and inside the receiving cavity 5. Multiple top cores 7 are detachably installed on the bottom layer 1. The multiple top cores 7 are inserted or threadedly connected to the bottom layer 1. Multiple molding cores 6 are opened on the top layer 2. The core 6 has a molding cavity 8 that is compatible with it. Multiple through holes 9 are formed on the core layer 3 that are compatible with the top core 7. The top core 7 can pass through the core layer 3 through the through holes 9. A core column cavity 10 is formed inside the core layer 3 and above the through holes 9 for forming the core column on the sealing cover. An undercut cavity 11 is formed on the core layer 3 and at the bottom of the core column cavity 10, which can form an undercut on the core column. The sealing cover can then be snapped on by the core column and the undercut, so that it does not need to be fixed by external structures such as screws, thus increasing the effectiveness of the sealing cover.

[0021] Furthermore, refer to Figure 5An upper drive mechanism 13 is fixedly connected to the top of the frame 12. The top of the top layer 2 is connected to the telescopic shaft of the upper drive mechanism 13. A lower drive mechanism 14 is fixedly connected to the bottom of the frame 12. The bottom of the bottom layer 1 is connected to the telescopic shaft of the lower drive mechanism 14. The drive mechanism controls the top layer 2 and the bottom layer 1 to move closer to or separate from the core layer 3, thereby realizing mold closing or mold separation.

[0022] Furthermore, a slide rail 15 is fixedly connected to the frame 12. There are two core layers 3, which are fixedly connected by a connecting rod. The two sides of the two core layers 3 are slidably connected to the two sides of the slide rail 15. The position of the slide rail 15 closer to the frame 12 is the right side, and the position farther away from the frame 12 is the left side. Two limit seats 16 are fixedly connected to the top of the slide rail 15 on both sides. A drive motor 17 is fixedly connected to the outside of one right limit seat 16. A lead screw 18 is fixedly connected to the output shaft of the drive motor 17. One end of the lead screw 18 is rotatably connected to the other right limit seat 16. A guide rod 19 is fixedly connected between the two left limit seats 16. Transmission blocks 20 are fixedly connected to the top of the two core layers 3 on both sides. The two right transmission blocks 20 are threadedly connected to the lead screw 18, which can simultaneously drive the two core layers 3 to move laterally, thereby achieving the molding of the sealing cap on the other core layer 3 while demolding. The two left transmission blocks 20 are slidably connected to the guide rod 19.

[0023] Furthermore, a baffle is fixedly connected to the connecting rod between the two core layers 3. The baffle is located between the two core layers 3 and can provide a layer of protection when the sealing cap is removed, thereby increasing its safety during use.

[0024] The implementation principle of this embodiment is as follows: During use, the lower drive mechanism 14 controls the bottom layer 1 to move upward, so that the bottom layer 1 and the core layer 3 are molded together. Then, an appropriate amount of rubber material is added into the cavity 5. The upper drive mechanism 13 controls the top layer 2 to move downward, thereby closing the mold and extruding the rubber. After it is completely cooled and molded, the upper drive mechanism 13 controls the top layer 2 to move, and the lower drive mechanism 14 controls the bottom layer 1 to move, thereby opening the mold. Then, the drive motor 17 is started, and the output shaft of the drive motor 17 drives the lead screw 18 to rotate. Through the threaded connection between the transmission block 20 and the lead screw 18, the two transmission blocks 20 drive the two core layers 3 to move along the slide rail 15. When the core layer 3 without a sealing cap is located at the position of the previous core layer 3, it stops. The core layer 3 with the molded sealing cap is located on the outside. Then, the sealing cap can be removed from the core layer 3 using a tool. At the same time, a new set of sealing caps can be molded. The molded sealing cap has a core post and a buckle, which enables convenient installation of the sealing cap and provides a good anti-detachment effect.
