Description

Technical Field

[0001] The invention relates to the technical field of pipette tip preparation, in particular to a forming mold for a pipette tip. Background Art

[0002] The molding of pipette tips is generally carried out using injection molds. Injection molds are a tool for producing plastic products; they are also tools that give plastic products a complete structure and precise dimensions. Injection molds are also a processing method used in mass production of parts, mainly used in the industrial field. The injection mold process is to inject the heated and melted material into the mold cavity under high pressure, and after cooling and solidification, a molded product is obtained; according to the molding characteristics, it is divided into thermosetting plastic molds and thermoplastic plastic molds.

[0003] At present, when the injection mold is in use, the injection molding machine injects a preset amount of plastic melt into the injection mold, and then waits for the plastic solution to cool and form to complete the production of the injection molded product. However, when the injection molded product is produced, after the plastic melt is injected into the injection mold, the injection molding head is currently used to pressurize the injection mold. However, the injection molding head pressurizes the injection molding solution in the injection mold by continuously injecting the injection molding solution. This pressurization method cannot achieve precise control of the injection pressure, and is prone to excessive or insufficient pressure. Too little pressure will cause insufficient distribution of the plastic liquid in the mold, and too much pressure will cause deformation of the mold, resulting in deviations in the size of the produced pipette tips, which cannot meet the design requirements. Uneven distribution of the plastic solution will cause production defects in the injection molded product, affecting the production quality of the pipette tips. Summary of the invention

[0015] Compared with the prior art, the present invention has the following beneficial effects: In the present invention, by providing a movable block, a second extension plate and a first lifting plate, after the lower mold and the upper mold are filled with plastic melt, the movable block abuts against the inner wall of the filling groove, at which time the movable block and the second extension plate complete the plugging of the filling groove, and the second extension plate moves downward to squeeze the plastic melt in the lower mold and the upper mold. Combined with the pressure sensor's measurement of the pressure value, the plastic melt can be pressurized, so that the plastic melt can fully fill every corner and detail of the mold, reducing defects caused by insufficient filling, such as shrinkage holes, depressions, etc., and improving the finished product quality of the pipette tip. The use of the pressure sensor can also achieve precise control of the internal pressure value of the upper mold and the lower mold; When the pipette tip needs to be demolded after the injection molding is completed, the second extension plate moves upward to the inside of the filling groove, so that the bottom of the second extension plate is separated from the pipette tip. Then, while the upper mold rises, the second extension plate moves downward. The downward movement of the second extension plate can assist the pipette tip in demolding from the upper mold, thereby increasing the convenience of using the device. When cleaning the upper mold and the lower mold, the inside of the filling groove is difficult to clean. The injection head of the injection molding machine is separated from the filling port and moves to a preset position. The top of the first lifting plate abuts against the bottom of the filling groove, and then the movable block drives the second extension plate to move back to the inside of the fourth slot. During the movement of the movable block, the plastic residue remaining on the movable block and the second extension plate will fall to the top of the first lifting plate, and then the first lifting plate continues to move upward until the top of the first lifting plate rises to the same horizontal height as the top of the filling port, so that the plastic residue can be ejected, the filling groove is cleaned, and the device is more convenient to use. The first lifting plate is driven to extend upward by the third electric telescopic rod, and the first lifting plate is used to lift the pipette tip upward, which can assist in demolding the pipette tip from the lower mold. When the first lifting plate pushes the pipette tip to a preset height position, the pipette tip is clamped by a manipulator preset outside the device, and then the first lifting plate is reset and moves downward until the first lifting plate moves to a preset state position. At this time, the manipulator preset outside the device clamps the pipette tip for unloading. The unloading of the finished pipette tip is completed through this operation mode, which increases the convenience of using the device.

[0016] In the present invention, a fixed plate and a movable plate are provided. After the lower mold and the upper mold are filled with plastic melt and the filling head of the injection molding machine leaves the filling port, the fixed plate extends downward, and the fixed plate extends from the filling port into the interior of the filling tank until the bottom of the movable plate moves to below the bottom of the fourth slot. In the process of the fixed plate extending downward, the fixed plate and the movable plate can scrape off the residual plastic melt on the filling port and the inner wall of the filling tank, thereby preventing the residual plastic melt from remaining on the filling port and the inner wall of the filling tank to affect the next use of the device, thereby increasing the functional stability of the device. When the first lifting plate pushes the plastic residue remaining on the second extension plate to the top of the filling port, the two movable plates move closer to each other, and the two movable plates can clamp the plastic residue on the top of the first lifting plate. Then, the electric lifting rod can drive the fixed plate to move, so as to unload the plastic residue clamped by the movable plate, complete the cleaning of the filling tank, and increase the convenience of the device. In addition, the excess plastic residue generated during the injection molding process can be collected in a centralized manner, so that the excess waste plastic can be recycled and reused. The remaining waste plastic will not flow into the external environment and be polluted, and it can still have a high quality after recycling and reuse. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] As a technical optimization solution of the present invention, the second auxiliary mechanism includes a second extension plate 26, and the second extension plate 26 is movably mounted on the bottom of the movable block 22. The movement of the second extension plate 26 enables the device to meet different operation requirements.

[0026] As a technical optimization solution of the present invention, a plurality of fifth slots 28 are evenly formed at the bottom of the movable block 22, a fixed block 30 is movably installed inside the fifth slot 28, a connecting block 31 is movably installed at one end of the fixed block 30 away from the movable block 22, and one end of the connecting block 31 close to the second extension plate 26 is connected to the second extension plate 26. By movably connecting the second extension plate 26 with the connecting block 31, the second extension plate 26 can be converted into a corresponding usage mode according to different usage requirements, thereby increasing the convenience of use of the device.

[0027] As a technical optimization solution of the present invention, a fourth electric telescopic rod 29 is installed at the top of the inner wall of the fifth slot 28, and the telescopic end of the fourth electric telescopic rod 29 faces the fixed block 30, and the telescopic end of the fourth electric telescopic rod 29 is connected to the fixed block 30. The fourth electric telescopic rod 29 extends downward, so that the second extension plate 26 moves downward, and the second extension plate 26 can squeeze the plastic melt in the lower mold 1 and the upper mold 2 during the downward movement.

[0028] As a technical optimization solution of the present invention, a sixth slot 32 is provided at one end of the fixed block 30 away from the fourth electric telescopic rod 29, and an end of the connecting block 31 close to the fixed block 30 is slidably installed inside the sixth slot 32, a pressure sensor 33 is installed at the top of the inner wall of the sixth slot 32, and a spring telescopic rod 34 is installed at the top of the connecting block 31, and the end of the spring telescopic rod 34 close to the pressure sensor 33 is connected to the pressure sensor 33. During the downward movement of the second extension plate 26, the second extension plate 26 squeezes the connecting block 31 under the reaction force of the plastic melt, and the connecting block 31 slides toward the inside of the sixth slot 32 and squeezes the spring telescopic rod 34. The spring telescopic rod 34 squeezes the pressure sensor 33, and the pressure sensor 33 transmits the measured pressure value to the background control system. The fourth electric telescopic rod 29 continues to extend downward until the pressure value measured by the pressure sensor 33 reaches the preset pressure value. The second extension plate 26 pressurizes the plastic melt inside the lower mold 1 and the upper mold 2, so that the plastic melt can fully fill every corner and detail of the mold, reduce defects caused by insufficient filling, such as shrinkage holes, depressions, etc., and improve the finished product quality of the pipette tip.

[0029] As a technical optimization scheme of the present invention, a second slot 13 is provided at the top of the inner part of the lower mold 1, a third electric telescopic rod 15 is installed at the bottom of the inner wall of the second slot 13, the telescopic end of the third electric telescopic rod 15 faces upward, and a first lifting plate 14 is movably installed inside the second slot 13, and the bottom end of the first lifting plate 14 is connected to the telescopic end of the third electric telescopic rod 15. When cleaning the upper mold 2 and the lower mold 1, it is difficult to clean the inside of the filling slot 20, the injection head of the injection molding machine is separated from the filling port 8 and moves to a preset position, the top of the first lifting plate 14 abuts the bottom of the filling slot 20, and then the movable block 22 drives the second extension plate 26 to move back to the inside of the fourth slot 21. During the movement of the movable block 22, the plastic residues remaining on the movable block 22 and the second extension plate 26 will fall to the top of the first lifting plate 14, and then the first lifting plate 14 continues to move upward until the top of the first lifting plate 14 rises to the same horizontal height position as the top of the filling port 8, so that the plastic residues can be ejected.

[0030] When the present invention is in use, the electrical mechanisms in the device are all powered by an external power supply through a wire. The electrical mechanisms in the device are controlled by setting a control system. The upper mold 2 and the lower mold 1 are existing mature technologies, so they will not be elaborated on in detail. When the device is in use, it is connected to the filling port 8 through the injection head of the injection molding machine. The connection method between the injection molding machine and the filling port 8 is an existing mature technology, so it will not be elaborated on in detail. A threaded hole is provided on the top of the upper mold 2, and the telescopic end of the hydraulic rod is connected to the upper mold 2 by installing a bolt into the threaded hole, so that the upper mold 2 can be lifted up and down.

[0031] After the plastic melt is filled in the lower mold 1 and the upper mold 2 and the filling head of the injection molding machine leaves the filling port 8, the electric lifting rod 3 is driven by the first rotating motor 12 to rotate, so that the fixed plate 6 rotates to the top of the filling port 8, and then the fixed plate 6 is driven by the first electric telescopic rod 5 to extend downward, and the fixed plate 6 extends from the filling port 8 into the interior of the filling tank 20 until the bottom of the movable plate 7 moves to below the bottom of the fourth slot 21. In the process of the fixed plate 6 extending downward, the fixed plate 6 and the movable plate 7 can scrape down the residual plastic melt on the inner wall of the filling port 8 and the filling tank 20, so as to prevent the plastic melt from remaining on the inner wall of the filling port 8 and the filling tank 20 and affecting the next step of the device, thereby increasing the functional stability of the device.

[0032] Then the fixed plate 6 moves upward until the bottom of the movable plate 7 moves to above the top of the filling port 8. At this time, the electric slider 24 slides inside the slide groove 23, so that the movable block 22 moves out of the fourth slot 21 until the movable block 22 abuts against the inner wall of the filling slot 20. At this time, the movable block 22 and the second extension plate 26 complete the blocking of the filling slot 20. Then the fourth electric telescopic rod 29 extends downward, so that the second extension plate 26 moves downward. During the downward movement of the second extension plate 26, the plastic melt in the lower mold 1 and the upper mold 2 can be squeezed. At this time, the second extension plate 26 The connecting block 31 is squeezed under the reaction force of the plastic melt, and the connecting block 31 slides toward the inside of the sixth slot 32 and squeezes the spring telescopic rod 34. The spring telescopic rod 34 squeezes the pressure sensor 33, and the pressure sensor 33 transmits the measured pressure value to the background control system. The fourth electric telescopic rod 29 continues to extend downward until the pressure value measured by the pressure sensor 33 reaches a preset pressure value. The second extension plate 26 pressurizes the plastic melt inside the lower mold 1 and the upper mold 2, so that the plastic melt can fully fill every corner and detail of the mold, reducing defects caused by insufficient filling.

[0033] When the pipette tip needs to be demoulded after the injection molding is completed, the second extension plate 26 moves upward to the inside of the filling groove 20, so that the bottom of the second extension plate 26 is separated from the pipette tip, and then the second extension plate 26 moves downward while the upper mold 2 rises. The downward movement of the second extension plate 26 can assist the pipette tip to be demoulded from the upper mold 2. When the upper mold 2 rises to a preset height position and stops moving, the first lifting plate 14 is driven by the third electric telescopic rod 15 to extend upward, and the pipette tip is lifted up by the first lifting plate 14, which can assist the pipette tip to be demoulded from the lower mold 1. When the first lifting plate 14 lifts the pipette tip to a preset height position, the pipette tip is clamped by a preset manipulator outside the device, and then the first lifting plate 14 is reset and moves downward until the first lifting plate 14 moves to the preset height position. Figure 5 In the state position shown, a preset manipulator outside the device clamps the pipette tip for unloading. This operation method completes the unloading of the pipette tip, which increases the convenience of using the device.

[0034] When cleaning the upper mold 2 and the lower mold 1, after the staff finishes cleaning the cores of the lower mold 1 and the upper mold 2, the inside of the filling groove 20 is difficult to clean, and the injection head of the injection molding machine is separated from the filling port 8 and moves to a preset position, and then the first lifting plate 14 moves upward so that the top of the first lifting plate 14 abuts against the bottom of the filling groove 20, and the movable block 22 drives the second extension plate 26 to move back to the inside of the fourth slot 21. During the movement of the movable block 22, the plastic residue remaining on the movable block 22 and the second extension plate 26 will fall to the top of the first lifting plate 14, and then the first lifting plate 14 continues to move upward until the top of the first lifting plate 14 rises to the filling port 8. The two movable plates 7 are at the same horizontal height as the top of the filling port 8, at this time, the fixed plate 6 moves to just above the filling port 8, and then the second electric telescopic rod 10 drives the two movable plates 7 to move away from each other until the movable plate 7 moves to the preset position, and then the fixed plate 6 moves downward until the bottom of the movable plate 7 moves to a position at the same horizontal height as the top of the filling port 8, and then the two movable plates 7 move closer to each other, and the two movable plates 7 can clamp the plastic residue on the top of the first lifting plate 14, and then the fixed plate 6 can be driven to move by the electric lifting rod 3, so as to unload the plastic residue clamped by the movable plate 7, thereby completing the cleaning of the filling tank 20 and increasing the convenience of use of the device.
