Technical Field
[0001] This utility model relates to the field of medical device manufacturing technology, and in particular to a high-efficiency infusion filter multi-material co-injection molding equipment. Background Technology
[0002] In the field of medical devices, infusion filters are a key component of infusion systems, used to filter impurities, particles and microorganisms in infusions to ensure the safety and effectiveness of infusions. With the growth of medical needs, the production efficiency and manufacturing precision of infusion filters have become the focus of industry attention. In the manufacturing process of infusion filters, injection molding is widely used due to its high efficiency and mass production characteristics.
[0003] The working principle of injection molding equipment is to heat and melt thermoplastic granules and inject them into the mold cavity. After cooling and solidification inside the mold, the desired shape of the part is formed. After molding, the mold needs to eject the finished product from the cavity through an ejection mechanism. However, the ejection mechanisms in the existing technology generally have problems with incomplete ejection or failure to eject, and do not fully consider the special structural requirements of infusion filter products, which directly affects the integrity of the product and the continuous operation capability of the equipment.

[0015] In a preferred embodiment, a stamping part is fixedly installed at the bottom center of the upper mold, and an electric push rod is fixedly installed on the inner wall of the mounting groove. The piston rod of the electric push rod is fixedly connected to one side of the U-shaped part a.
[0016] By adopting the above technical solution, the extension and retraction of the piston rod of the electric push rod can push the U-shaped part a to move, thereby driving the entire U-shaped part b and the T-shaped limiting plate to move.

After the injection molding on the mold is completed, the movement of the U-shaped part a13 can drive the entire U-shaped part b15 and the T-shaped limiting plate 16 to move. At this time, the U-shaped part b15, U-shaped part a13 and T-shaped limiting plate 16 are all on the outside of the limiting frame 17, while one end of the U-shaped part b15 will abut against the inner wall of the mounting groove 9. Then, the connecting rod 14 can push the U-shaped part b15 and the T-shaped limiting plate 16 upward, so as to facilitate the finished product embedded in the stamping groove to be pushed out of the cavity. The T-shaped limiting plate 16 is made of polypropylene, which can reduce damage to the finished product while ensuring hardness.
[0029] Specifically, a T-shaped limiting plate 16 is slidably connected inside the limiting frame 17. The bottom of the T-shaped limiting plate 16 is fixedly connected to the U-shaped part b15. Through the coordinated cooperation of the T-shaped limiting plate 16 and the limiting frame 17, the U-shaped part b15 can be made more stable during sliding and less prone to shaking. The T-shaped limiting plate 16 is a polypropylene component. A limiting component is provided inside the fixing part 11. The limiting component includes limiting grooves 12 opened on both sides of the inner wall of the fixing part 11. Limiting blocks 4 are slidably connected inside the limiting grooves 12. Through the limiting blocks 4 and the limiting... The use of groove 12 can limit the U-shaped part a13 to ensure the normal operation of the lifting operation. The two limit blocks 4 are fixedly connected to both sides of the U-shaped part a13. The four corners of the top of the base 1 are fixedly connected to positioning rods 3. The positioning rods 3 play an important positioning role in the lifting of the upper mold 5, ensuring that the upper mold 5 moves vertically during the stamping process. The tops of several positioning rods 3 are fixedly connected to a top plate 6. The upper mold 5 is set between the base 1 and the top plate 6. The upper mold 5 is slidably connected to the positioning rods 3.
[0030] Specifically, an injection cylinder 7 is fixedly installed on the top of the top plate 6. The piston rod of the injection cylinder 7 passes through the interior of the top plate 6 and is fixedly connected to the upper mold 5. By extending and retracting the piston rod of the injection cylinder 7, the upper mold 5 can be pushed down, thereby achieving the stamping purpose of the mold with the help of the stamping part 8. The stamping part 8 is fixedly installed at the bottom center of the upper mold 5. An electric push rod 10 is fixedly installed on the inner wall of the mounting groove 9. The piston rod of the electric push rod 10 is fixedly connected to one side of the U-shaped part a13. The injection cylinder 7 and the electric push rod 10 can be started and stopped by the controller. A controller is fixedly installed on the outside of the base 1. The injection cylinder 7 and the electric push rod 10 are electrically connected to the controller.
[0031] Working principle: First, the operator places the mold in the lower mold 2 and pours the injection liquid into it. Then, the controller starts the injection cylinder 7. The extension and retraction of the piston rod of the injection cylinder 7 pushes the upper mold 5 downward, thereby achieving the stamping purpose of the mold with the help of the stamping part 8. After the mold on the lower mold 2 is filled with molded material, the electric push rod 10 is started. The extension and retraction of the piston rod of the electric push rod 10 pushes the U-shaped part a13 to move, thereby driving the entire mold. The U-shaped part b15 and the T-shaped limiting plate 16 move. At this time, the U-shaped part b15, U-shaped part a13 and the T-shaped limiting plate 16 are all on the outside of the limiting frame 17, and one end of the U-shaped part b15 will abut against the inner wall of the mounting groove 9. Then, the connecting rod 14 can push the U-shaped part b15 and the T-shaped limiting plate 16 upward, so as to facilitate the finished product embedded in the stamping groove to be pushed out of the cavity. The T-shaped limiting plate 16 is made of polypropylene, which can reduce damage to the finished product while ensuring hardness.
