Description

Technical Field

[0001] The present invention relates to the technical field of production molds, in particular to a test tube structure production mold containing an embedded RFID and a preparation method thereof. Background Art

[0002] Currently, injection molding or blow molding technology for mass-producing conventional test tubes is quite mature. The core structure of these molds focuses on efficiently and accurately forming the basic geometric shapes of the test tube body, base, and nozzle, ensuring dimensional consistency, sealing, and sufficient mechanical strength to meet the needs of routine sampling, storage, and transportation. With the rapid development of smart laboratories and the demand for sample tracking and management, the application of smart test tubes with embedded RFID tags is becoming increasingly prominent. These test tubes enable contactless, automated identification and data management throughout the sample life cycle, significantly improving processing efficiency and reducing error rates.

[0003] However, the existing production of test tubes with embedded RFID has a key limitation. RFID tags are mostly placed on bottle caps or attached to the surface of test tubes. They are easily contaminated and can be easily tampered with or leak medical data if removed. They cannot be permanently embedded in the tube body, and there is a risk of sample information being maliciously leaked or tampered with. Therefore, combining the RFID tag with the tube body is an effective solution to prevent information tampering and leakage. However, mainstream molds do not have a production and processing structure designed to accommodate the chip in the tube body, making it impossible to combine the test tube and RFID tag during the production and processing process. These problems seriously restrict the safety and industrialization process of medical-grade smart test tubes. Summary of the Invention

[0041] S1: Split molding stage, S1-1, remove the lower mold 18, and fix the injection molding tube by the fixing clamp 53 of the tube carrier 20; S1-2, start the electric cylinder 13 to push the column tube frame 14 up, so that the columnar tube on the column tube frame 14 is completely inserted into the column groove 46 of the bottom mold 15, filling the hollow space below the bottom mold 15; S1-3, install the lower mold 18, and inject the melt into the column groove 46 of the bottom mold 15 and the column hollow tube 44 in the lower mold 18, so that the column hollow tube 44 and the lower bottom 45 surround the melt; S1-4, start the longitudinal drive mechanism, drive the upper mold 19 to press down, and the lower pressure tube 48 of the upper mold 19 is inserted into the column hollow tube 44 to squeeze the melt in the column hollow tube 44 to form a long test tube prototype, and then the column hollow The tube 44 squeezes the column groove 46 downward to form the test tube bottom cavity, and the blowing assembly 21 starts the air nozzle 2104 to blow cold air to cool the lower mold 18; S1-5, after the upper mold 19 is reset, the cooled lower mold 18 is removed, and the electric cylinder 13 uses the column tube rack to push out the molded part in the bottom mold 15 to form the test tube bottom cavity, and the molded test tube bottom cavity is removed; S1-6, the lower bottom 45 of the lower mold 18 is removed, and the lower mold 18 is placed back on the top of the bottom mold 15; S1-7, the upper mold 19 is pressed down again and then the lower mold 18 is manually lifted up with a tool, so that the molded part in the column hollow tube 44 is separated from the lower mold 18, and a long test tube body is obtained; S1-8, the surrounding defects can now be polished separately under the action of the polishing wire 28;

[0042] S2: Chiming assembly stage, S2-1, fix the bottom cavity of the test tube in the lower ferrule 38 of the rear chamber 31, and drive the tightening block 4102 to lock it by pushing the screw 4101; S2-2, place the RFID chip in the bottom cavity of the test tube and then place insulation material above the RFID chip to prevent the test tube from affecting the RFID chip; S2-3, the upper end of the long test tube is fixed by the clamp assembly 41 of the upper ferrule 37; S2-4, adjust the height of the lifting cylinder 36 so that the lower end of the long test tube is connected to the bottom cavity of the test tube; S2- 5. The moving block 3001 slides along the moving rail 29, and the L-shaped support tube 3002 drives the half clamp 3003 to cover the connection, and the heating wire 3004 is started to heat the fusion interface; S2-6. The lower ferrule 38 is released, and the servo motor 27 is started to drive the grinding wire 28 to rotate; S2-7. The rotating motor 35 is started synchronously to drive the test tube to rotate, and the grinding wire 28 grinds the fusion part circumferentially; S2-8. The water pump 23 draws water from the water tank 22, and rinses the polished part through the nozzle 25 to complete the fine processing.

[0043] Collaborative injection molding can protect the RFID chip from the influence of high temperature, and it can be placed in after secondary processing, which is safe and reliable. The column tube frame 14 is inserted into the column groove 46 of the bottom mold 15 to form a closed cavity. After the molten body is injected, it is surrounded by the column hollow tube 44 of the lower mold 18. When the upper mold 19 is pressed down, the lower pressure tube 48 squeezes the molten body to form a long test tube body. At the same time, the column hollow tube 44 presses down the bottom mold 15 to melt and form a test tube bottom cavity. The electric cylinder 13 pushes the column tube frame 14 out of the test tube bottom cavity, and the long test tube body is pushed out by the upper mold 19 for the second time to avoid demoulding damage. The blowing component 21 sprays cold air on the bottom mold 15 to accelerate solidification. The lower ferrule 38 fixes the test tube bottom cavity and embeds the RFID chip. The upper ferrule 37 clamps the long test tube body, so that the test tube bottom cavity is slightly larger than the diameter of the long test tube, so that the test tube bottom cavity can slightly include the upper end of the bottom of the long test tube. The circumferential side enhances the convenience and stability of the adhesion of the two main bodies. The half-clamp 3003 of the heating component 30 heats the interface to achieve local melt bonding. The rotating motor 35 drives the test tube to rotate. The servo motor 27 controls the grinding wire 28 to grind the interface circumferentially. The nozzle 25 synchronously sprays cooling water and removes debris. The test tube bottom cavity and the long test tube body are synchronously formed through a separate mold. The blowing component 21 directionally cools the temperature. The clamp component 41 realizes zero-displacement fixation of the test tube bottom cavity to ensure that the RFID chip is embedded without offset. The threaded connection between the column hollow tube 44 and the lower bottom 45 realizes quick disassembly and assembly. The rear warehouse 31 integrates the functions of fitting, grinding, and cleaning. A single station completes the three processes of the traditional production line, reducing equipment costs. It can mass-produce precision plastic products such as medical specimen test tubes and high-value drug traceability tubes that require embedded RFID tags.
