[0004] However, due to lack of accurate control of plastic quantity in injection molding process, there are differences in the amount of plastic entering the mold cavity during molding of different batches or even the same batch, this inconsistency of plastic quantity will cause different parts of plastic in the mold to show different cooling rates during cooling, some areas have more plastic, and cooling is relatively slow, some areas have less plastic, and cooling is relatively fast, which makes the test tube produce greater internal stress due to local cooling anomaly during cooling, and further causes deformation, affecting the roundness, straightness and other key quality indicators of test tube, and cannot stably meet the strict requirements of medical use, therefore, a kind of high-efficiency cooling's medical test tube forming mould is proposed to solve the above problems.

[0030] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] ReferenceFigure 1 - Figure 3 This utility model provides an embodiment of a high-efficiency cooling medical test tube forming mold, including a support 1. An electric push rod 2 is fixedly connected to the side wall of the support 1 by welding. The electric push rod 2 can control the moving distance and speed of the push plate 3. Its shell is made of aluminum alloy, which ensures sufficient strength and reduces the overall weight. The output end of the electric push rod 2 is fixedly connected to the push plate 3. The push plate 3 achieves smooth sliding connection on the track through a slider. A cooler 4 is fixedly connected to the side wall of the push plate 3 by bolts. The main shell of the cooler 4 is made of stainless steel and has a complex cooling water channel inside. The cooling water channel is made of copper pipe to improve heat conduction efficiency. A metering component is provided on the side wall of the support 1 for accurately controlling the amount of plastic extruded. An extrusion component is provided on the side wall of the support 1. A lifting component is provided on one side of the push plate 3 to smoothly eject the test tube after it is formed and cooled.
[0032] The quantitative component includes a material barrel 11, which is cylindrical in shape and made of stainless steel, providing corrosion resistance and pressure resistance. A heater 5 is installed on the outer wall of the material barrel 11. A hydraulic rod 10 is fixedly connected to the side wall of the heater 5 by welding. The side wall of the hydraulic rod 10 is fixedly connected to the side wall of the material barrel 11. When the hydraulic rod 10 is activated, it can drive the material barrel 11 to move. A placement plate 6 is fixedly connected to the top of the material barrel 11. A connecting plate 12 is fixedly connected to the side wall of the heater 5. The connecting plate 12 is U-shaped and has a hopper 7 fixedly connected to its top. The outer wall of the placement plate 6 is slidably connected to the inside of the connecting plate 12 to ensure that there is no jamming during the sliding process. A material cover 13 is rotatably connected to the bottom of the material barrel 11. When the material barrel 11 moves, the material cover 13 will open or close accordingly, realizing the quantitative extrusion of plastic raw materials.
[0033] Specifically, the high-efficiency cooling medical test tube forming mold operates by first injecting plastic into the hopper 7, then into the heating machine 5, and finally into the cooling machine 4. Inside the cooling machine 4, the mold rapidly removes heat with circulating water, allowing the plastic to cool and solidify quickly. When there are differences in the amount of plastic, the test tube may cool too quickly or too slowly in some areas. Once uneven cooling is detected, the hydraulic rod 10 is activated, which moves the material bucket 11. As the material bucket 11 moves, the placement plate 6 on top also moves accordingly. The outer wall of the placement plate 6 slides smoothly inside the connecting plate 12 until it completely blocks the top of the material bucket 11. At the same time, the material cover 13 at the bottom of the material bucket 11 moves and opens, allowing the plastic inside the material bucket 11 to enter the heating machine 5 through the feed port 8, thereby heating the raw material. This reduces deformation caused by uneven cooling and makes the test tubes more compliant with medical use standards.
[0034] Reference Figure 1 , Figure 2 andFigure 4 The extrusion assembly includes a die head 9, which is precision machined from alloy steel to ensure uniform and stable extrusion of the plastic melt. The sidewall of the die head 9 is located inside the cooler 4 to ensure timely cooling and shaping of the plastic during the extrusion process. The sidewall of the support 1 is located on one side of the heater 5. The outer wall of the heater 5 has a feed inlet 8, which facilitates the injection of plastic raw materials. The sidewall of the heater 5 is located on one side of the hopper 7. The lifting assembly includes a sliding column 19, the outer wall of which is slidably connected to the inner wall of the cooler 4. The sidewall of the push plate 3 is equipped with a hydraulic rod 14, the output end of which is fixedly connected to a limit block 15. The limit block 15 is a cuboid structure made of aluminum alloy, which is lightweight and easy to process. A sliding block 16 is fixedly connected to the side by welding. The sliding block 16 has a groove inside that matches the side wall of the push plate 3, allowing it to slide flexibly on the side wall of the push plate 3. A roller 17 is slidably connected to the other side of the limiting block 15. The roller 17 is made of bearing steel and its surface is ground, allowing it to rotate flexibly. The outer wall of the roller 17 is rotatably connected to the side wall of the sliding column 19. A spring 18 is sleeved on the outer wall of the sliding column 19. One end of the spring 18 is fixedly connected to the side wall of the roller 17, and the other end of the spring 18 is fixedly connected to the outer wall of the push plate 3. When the hydraulic rod 14 is activated, it will drive the limiting block 15 to move, thereby causing the roller 17 to slide on the side wall of the sliding column 19, compressing the spring 18, realizing the position control of the sliding column 19, and finally completing the demolding operation of the test tube.
[0035] In the cooling process of medical test tube forming, poor air circulation often occurs. At this point, hydraulic rod 14 activates, pushing sliding block 16 along the track. The movement of sliding block 16 causes limiting block 15 to move synchronously, subsequently driving roller 17 to roll on the side wall of limiting block 15. When roller 17 reaches the top of the side wall of limiting block 15, spring 18 is compressed and contracts, causing sliding column 19 to press tightly against the side wall of cooling machine 4. Cooling machine 4 then begins operation to cool the material in the forming stage. After the cooling process is completed, hydraulic rod 14 is activated again, pushing sliding block 16 once more. The sliding block 16 causes the limiting block 15 to move. As the limiting block 15 moves, the roller 17 rolls down along the side wall of the limiting block 15 to the bottom. The spring 18 gradually returns to its original shape under the action of the roller 17 and begins to retract. The retraction of the spring 18 causes the sliding column 19 to move, causing it to disengage from the side wall of the cooler 4. Subsequently, the lifting mechanism pushes the test tube out of the mold. After the test tube is demolded, the demolding process can be made more stable and efficient, without spending too much manpower and time on the demolding operation. This reduces the production cycle of a single test tube, improves the overall production efficiency, and provides a strong guarantee for the large-scale, high-quality production of medical test tubes.
[0036] Working principle: During the medical test tube molding process, differences in the amount of plastic can cause local cooling to be too fast or too slow. At this time, the hydraulic rod 10 is activated, which drives the material barrel 11 to move. Then, the placement plate 6 on the top of the material barrel 11 is moved horizontally. Then, the outer wall of the placement plate 6 slides inside the connecting plate 12, thereby blocking the top of the material barrel 11. At the same time, the material cover 13 at the bottom of the material barrel 11 is also moved, so that the material cover 13 is opened, allowing the material to be extruded. This reduces the internal stress and deformation caused by uneven cooling, and ensures that the roundness, straightness and other indicators of the test tube meet the requirements.
[0037] When the medical test tube is being formed and cooled, air circulation may be obstructed. Activating hydraulic rod 14 causes sliding block 16 to slide, which in turn moves limit block 15 horizontally. Roller 17 then slides against the side wall of limit block 15. When it reaches the top, spring 18 is compressed, causing sliding column 19 to adhere to the side wall of the cooler 4, thus cooling the material. After cooling is complete, hydraulic rod 14 is activated again, causing sliding block 16 to slide, which in turn moves limit block 15. Roller 17 then slides to the bottom of limit block 15, causing spring 18 to retract, which in turn moves sliding column 19, disengaging it from the side wall of the cooler 4. The test tube is then lifted and demolded, effectively overcoming the adhesion problem between the test tube and the mold and improving overall production efficiency.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
