Description

Technical Field

[0001] The invention relates to the technical field of injection molds, in particular to a precision injection mold based on a chemiluminescence reaction cup. Background Art

[0002] The chemiluminescent reaction cup is a core consumable for quantitative analysis of biomarkers in in vitro diagnostic (IVD) equipment and is widely used in the quantitative analysis of biomarkers. It forms an immune complex by specifically binding to the target substance in the sample to be tested through specific antibodies or antigens. Subsequently, by adding a luminescent substrate, the presence of the immune complex is converted into a detectable light signal by chemiluminescence, thereby achieving accurate detection of the biomarker. The detection method displays the concentration of the biomarker based on the intensity of the light signal generated by the chemiluminescent reaction. Therefore, the performance of the chemiluminescent reaction cup directly determines the sensitivity of the detection and the accuracy of the results. In order to ensure that the chemiluminescent reaction cup can stably perform its detection function, a precision injection mold based on the chemiluminescent reaction cup is proposed to ensure the performance of the chemiluminescent reaction cup, thereby ensuring the reliability and repeatability of the detection results.

[0003] Publication No. CN115431471B4 discloses an injection mold for a sample cup. This solves the technical drawback that during demolding, a significant negative pressure is generated when the outer wall of the cup moves a considerable distance relative to the mold cavity. Similarly, a significant negative pressure is generated when the inner wall of the cup moves a considerable distance relative to the outer wall of the core. This can lead to difficulty in demolding, easy damage to the product, and a high defective rate. However, in actual use, similar structures still have many drawbacks. For example, existing injection molds often have difficulty effectively discharging residual material from the feed channel. Residual material remains on the surface of the reaction cup after molding, resulting in serious surface defects that directly affect the precision of the injection-molded product and require extensive manual polishing to correct. This not only wastes a significant amount of time and cost, but also increases the production cycle. Secondly, due to the lack of effective control of the air pressure environment in the mold cavity, negative pressure operation of the mold cavity and a precise demolding process cannot be achieved, which not only reduces production efficiency but also increases the defective rate and further increases production costs.

[0004] Therefore, the above technical problems need to be solved. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing technology, the present invention proposes a precision injection mold based on a chemiluminescent reaction cup to solve the problem that it is difficult to effectively discharge the residual material in the feed channel, and the residual material will remain on the surface of the reaction cup after molding, causing serious surface defects; and the lack of effective control of the air pressure environment in the mold cavity, resulting in the inability to achieve negative pressure operation of the mold cavity and precise demolding process, which not only reduces production efficiency, but also increases the defective rate, further increasing the production cost.

Through the cooperation between the telescopic assembly and the central material port opening and closing assembly, effective opening and closing control of the tapered material port is achieved, ensuring that the material can be smoothly injected and the sealed injection molding is completed, and the tapered material port at one end of the second mold cavity is closed to ensure that the residual material in the tapered material port is squeezed out, significantly reducing surface defects, thereby ensuring the integrity of the bottom of the reaction cup and the injection molding quality, not only improving the injection molding accuracy, but also simplifying the subsequent polishing and shaping steps, and effectively improving the injection molding efficiency.

[0020] The linked air control mechanism controls the air pressure in the mold cavity through changes in gas pressure, using pipes and air valves to form a negative pressure environment or perform exhaust operations; the negative pressure environment reduces the gas content in the mold cavity, thereby reducing the probability of bubbles generated inside the chemiluminescent reaction cup, while accelerating the flow of material in the mold cavity, improving the uniform distribution of the material and the injection molding quality; and the exhaust operation pushes the already shaped reaction cup out of the second mold cavity, which not only helps to separate the reaction cup from the inner wall of the second mold cavity, but also further accelerates the cooling and shaping process of the reaction cup; in summary, the linked air control mechanism not only improves the production and injection molding quality of the chemiluminescent reaction cup through gas control, but also enhances its cooling efficiency, thereby ensuring the performance stability and reliability of the final product, so that the performance of the chemiluminescent reaction cup reaches higher quality standards, and further improves the accuracy and reliability of the test results.

DETAILED DESCRIPTION

[0042] The following will be combined with the Figure 1 To the attached Figure 19 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] A precision injection mold based on a chemiluminescent reaction cup includes a fixed mold 1, a demoulding mold 2, a movable mold 3, and a material port opening and closing mechanism 6. It also includes a mounting base 5 fixedly mounted on one side of the movable mold 3, and two linked air control mechanisms 4 fixedly mounted on both sides of the movable mold 3, and one end of each of the two linked air control mechanisms 4 is fixedly connected to both sides of the demoulding mold 2. A feed valve pipe 301 is installed through the top of the movable mold 3, and an air valve 302 is installed through one side of the feed valve pipe 301. The feed valve pipe 301 is connected to the two linked air control mechanisms 4 via a pipeline.

[0044] Guide rods 101 are fixedly installed at the four corners of the side of the fixed mold 1, and one side of the fixed mold 1 is movably connected to the demoulding mold 2 through the guide rods 101;

[0045] It should be noted that the fixed mold 1 and the movable mold 3 are guided by the guide rod 101 and the guide pin hole 304 to achieve precise alignment and stable movement; the demoulding mold 2 is used to dock with the movable mold 3, provide a fixed molding space, and cooperate to complete the demoulding action; the movable mold 3 moves toward the demoulding mold 2 under a specific drive, and finally docks with the demoulding mold 2 to form a complete mold structure; the mounting seat 5 serves as an auxiliary structure of the movable mold 3, transmitting the force generated during the movement to the linkage air control mechanism 4; the linkage air control mechanism 4 generates a vacuum or exhaust operation through the force movement, and regulates the negative pressure environment or positive pressure environment between the first mold cavity 201 and the second mold cavity 303 through the air valve 302; the driving material port opening and closing mechanism 6 opens the conical feed port during the mold closing action to allow raw materials to enter the mold cavity; the air valve 302 controls the entry or discharge of air flow in the mold cavity according to work needs.

[0046] The material port opening and closing mechanism 6 is embedded and installed inside the mounting base 5. The material port opening and closing mechanism 6 is composed of a transmission ring 601, a rotating component 602, a telescopic component 603, a central material port opening and closing component 604 and a transmission component 605. The outer side of the transmission ring 601 is provided with an external tooth groove 6011, and the side ring array of the transmission ring 601 has multiple toggle blocks 6012. The outer side of the transmission ring 601 is rotatably sleeved with multiple rotating components 602, and the multiple rotating components 602 are distributed in a ring array. The transmission ring 601 is connected to the rotating component 602 through the toggle block 6012. The inner sides of the multiple rotating components 602 are all connected to the telescopic component 603, and one of the telescopic components 603 is connected to the rotating component 602. The end extends to the interior of the movable mold 3, and the outer side of the transmission ring 601 is transmission-connected to the transmission component 605 through the external tooth groove 6011. The output end of the transmission component 605 is transmission-connected to the central material port opening and closing component 604, and the central material port opening and closing component 604 is located at the center of the transmission ring 601. The transmission ring 601, the rotating component 602, the telescopic component 603, the central material port opening and closing component 604 and the transmission component 605 work together to realize the opening and closing control of the tapered feed port at one end of the mold cavity. The tapered feed port is opened to ensure the smooth injection of the material. The tapered feed port is closed to effectively squeeze out the residual material in the tapered feed port to ensure the integrity of the bottom end of the reaction cup.

[0047] It should be noted that the transmission assembly 605 provides power output through an external servo motor to drive its own operation. The running transmission assembly 605 drives the transmission ring 601 to rotate through its external tooth groove 6011, and drives the central material port opening and closing assembly 604 to telescopically move; when the transmission ring 601 rotates, the toggle block 6012 thereon cooperates with the rotating assembly 602 to further drive the telescopic assembly 603 to telescopically move, and move synchronously with the central material port opening and closing assembly 604. Through the coordinated work of the above-mentioned various components, effective opening and closing control of the tapered feed port is achieved, ensuring that the material can be smoothly injected and sealed injection molding is completed. Specifically, the tapered feed port is opened to ensure that the material is injected into the mold unimpeded, and then the tapered feed port is closed to seal the tapered feed port at one end of the second mold cavity 303, effectively squeezing out the residual material in the tapered feed port, effectively reducing surface defects, thereby ensuring the integrity of the bottom of the reaction cup and the injection molding quality, not only improving the injection molding accuracy, but also simplifying the subsequent polishing and shaping steps, and effectively improving the injection molding efficiency;

[0048] When the mold is closed, the material port opening and closing mechanism 6 is driven to open the conical feed port, and moves to the side of the demoulding mold 2 through the movable mold 3. When the movable mold 3 moves to the side of the demoulding mold 2, it abuts the demoulding mold 2 to move to the side of the fixed mold 1, so that the movable mold 3 is docked with the demoulding mold 2, and the demoulding mold 2 is docked with the fixed mold 1 in sequence. At the same time, when the movable mold 3 is docked with the demoulding mold 2, the movable movable mold 3 moves by abutting one end of the linkage air control mechanism 4 through the mounting seat 5, thereby driving the linkage air control mechanism 4 to perform an exhaust operation, and the negative pressure generated is transported to the opened air valve 302 through the pipeline. The opened air valve 302 transports the negative pressure through the conical feed port to the mold cavity formed by the docking of the first mold cavity 201 and the second mold cavity 303, so that a negative pressure environment is formed in the mold cavity, which is conducive to cooling and shaping;

[0049] When the movable mold 3 moves in the opposite direction to open the mold, the material port opening and closing mechanism 6 is driven to open the tapered material port. The movable mold 3 drives the linked air control mechanism 4 to perform exhaust operation. The exhausted gas is transported to the opened air valve 302 through the pipeline. The opened air valve 302 transports the gas through the tapered material port to the second mold cavity 303. The exhausted gas is used to push and demold the reaction cup formed in the second mold cavity 303.

[0050] It should be noted that the dynamic combination of the demoulding mold 2 with the fixed mold 1 and the movable mold 3 ensures smooth opening and closing of the mold, which is conducive to improving production efficiency;

[0051] The linkage gas control mechanism 4 forms a negative pressure environment in the mold cavity through the change of gas pressure and through the pipeline and the gas valve 302, and the negative pressure environment reduces the gas content in the mold cavity, reduces the probability of bubble of the chemiluminescence reaction cup, and at the same time, the negative pressure environment can increase the material flow, improve the uniform injection of the material in the mold cavity, and accelerate the cooling efficiency; and the exhaust can push the reaction cup in the second mold cavity 303 to demold, which not only can separate the reaction cup from the inner wall of the second mold cavity 303, but also can accelerate the cooling and shaping efficiency of the reaction cup in the second mold cavity 303, thereby improving the injection quality of the chemiluminescence reaction cup in the mold cavity.

[0052] As shown in Figures 15 to 18 The rotating assembly 602 is composed of a rotating pipe 6021 and an outer tooth ring 6023, the rotating pipe 6021 is internally provided with a plurality of curve tooth grooves 6022 arranged in an annular array, the curve tooth grooves 6022 are dynamically engaged with the poking block 6012, and the outer tooth ring 6023 is fixedly sleeved outside the rotating pipe 6021;

[0055] It should be noted that the rack 6031 in the telescopic assembly 603 is meshingly connected with the outer tooth ring 6023, so as to drive the meshingly connected rack 6031 to move up and down when the outer tooth ring 6023 rotates, and at the same time, the rack 6031 drives the first sealing plug 6033 to realize the axial telescopic function through the spline rod 6032, the spline rod 6032 extends through the spline through hole 306 into the feeding channel 307, and the spline rod 6032 moves up and down in the feeding channel 307, so as to drive the first sealing plug 6033 to open and close the conical feeding port;

[0057] It should be noted that the first bevel gear 6041 is rotatably installed at the inner center position of the installation chamber 501 through a rotating shaft, thereby ensuring the transmission stability of the first bevel gear 6041; the central material port opening and closing assembly 604 utilizes the cooperation of the first bevel gear 6041, the nut member 6042 and the threaded rod 6043 to drive the second sealing plug 6044 to axially telescopically move, thereby realizing the opening and closing control of the central conical feed port. Specifically, the power transmitted by the transmission assembly 605 is transmitted to the nut member 6042 through the first bevel gear 6041, so that the nut member 6042 rotates, and the rotating nut member 6042 drives the threaded rod 6043 to telescopically move through the internal threaded hole, and the telescopically moving threaded rod 6043 drives the second sealing plug 6044 to axially telescopically move, and the second sealing plug 6044 extends into the central conical feed port, thereby ensuring the sealing of the central conical feed port and discharging excess material from the central conical feed port;

[0058] The transmission assembly 605 consists of a transmission rod 6051, a worm 6052, a worm wheel 6053, a second bevel gear 6054, and a linkage gear 6055. One end of the transmission rod 6051 is meshed with the second bevel gear 6054, and the other end of the transmission rod 6051 is meshed with the first bevel gear 6041. The two sides of the second bevel gear 6054 are fixedly connected to the worm wheel 6053 and the linkage gear 6055, respectively. The linkage gear 6055 is meshed with the external tooth groove 6011. The worm wheel 6053 is meshed with the worm 6052, and a transmission shaft is fixedly mounted on the top of the worm 6052.
