Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to a medical syringe die with a quick-change die core. Background Technology

[0002] Injection molds are a processing method used for mass production of certain complex-shaped parts. They are mainly used in the industrial field. In the syringe injection mold process, the heated and molten material is injected into the gap between the upper mold body and the mold core. After cooling and solidification, the molded product is obtained. According to the molding characteristics, they are divided into two types: thermosetting plastic molds and thermoplastic plastic molds.

[0003] Traditional syringe molds have limitations: a single mold can only mold one type of syringe, the mold core cannot be quickly replaced, removing the mold core requires disassembling a large number of screws, and the high cost of mold making results in low applicability. In addition, a lot of time is required during installation to calibrate the mold core and prevent it from becoming misaligned. In order to address these technical problems, this application proposes a medical syringe mold with a quickly replaceable mold core. Utility Model Content

Detailed Implementation

[0016] 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.

[0017] Reference Figures 1-3 An embodiment of this utility model provides: a medical syringe mold with a quick-change mold core, including a lathe 1, a top plate 2 on the top side of the lathe 1, a movable plate 3 on the bottom side of the top plate 2, a cylinder 5 mounted on the outer wall of the top plate 2 by a fixed bracket, a stamping block 6 mounted on the bottom side of the movable plate 3 by a fixed bracket, a mold base 7 on the bottom side of the stamping block 6, a cylinder 13 on the bottom side of the mold base 7, a motor 12 mounted inside the top side of the lathe 1 by a fixed bracket, an injection chamber 9 fixedly connected to the rear side of the lathe 1, a gear assembly 11 on the drive end of the motor 12, the top of the gear assembly 11 connected to the mold base 7 by a locking component, and the bottom side of the gear assembly 11 connected to a push rod 14 by a fixed component; Specifically, during mold production, cylinder 5 on top plate 2 pushes the stamping block 6 on movable plate 3 closer to mold base 7 and into mold base 7. The sealing block at the end of stamping block 6 forms a sealed cavity inside mold base 7. Then, the material enters the cavity from injection chamber 9 through the injection hole on the bottom side of mold base 7. After cooling, cylinder 13 ejects the mold. When mold replacement is needed, motor 12 drives gear assembly 11 to operate. The drive end of motor 12 is equipped with bevel gear. When started, it drives the bevel gear on the rotating rod of gear assembly 11 to rotate, which in turn drives the flat gears at both ends of the rotating rod to rotate. Then, the flat gear at the top drives the locking component to unlock, and the flat gear at the bottom drives the transmission gear to rotate. Then, the transmission gear drives the fixing component to rotate, fixing the fixing component on top of cylinder 13. Then, cylinder 13 ejects mold base 7 from lathe 1. Then, other types of mold base 7 can be installed into lathe 1.

[0018] Reference Figure 4 and Figure 7The locking component includes a gear ring 16 located on the top side of the gear assembly 11. Multiple limit blocks 21 are fixedly connected to the inner wall of the gear ring 16. A positioning block 20 is provided on the outer wall of the limit block 21. The outer wall of the positioning block 20 is fixedly connected to the mold base 7. The flat gear at the top of the gear assembly 11 drives the gear ring 16 to rotate. Then, the gear ring 16 drives the limit block 21 on the inner wall of the gear ring 16 to rotate away from the positioning groove of the positioning block 20 on the outer wall of the mold base 7, thereby unlocking the mold base 7.

[0019] Reference Figures 4-6 The fixing component includes a gear ring 17 located on the bottom side of the gear assembly 11. Two fixing blocks 19 are fixedly connected to the inner wall of the gear ring 17. A connecting block 18 is provided on the outer wall of the fixing block 19. The inner wall of the connecting block 18 is fixedly connected to the push rod 14. An ejector block 15 is provided on the top of the push rod 14. The bottom side of the push rod 14 is connected to the driving end of the second cylinder 13. The outer wall of the ejector block 15 is slidably connected to the mold base 7. The transmission gear on the bottom side of the gear assembly 11 drives the gear ring 17 to rotate. Then, the fixing block 19 on the inner side of the gear ring 17 will rotate into the fixing hole of the connecting block 18, thereby fixing the connecting block 18. Thus, when the second cylinder 13 drives the push rod 14, it drives the gear ring 17 to eject the mold base 7.

[0020] Reference Figure 3 A water tank 8 is installed on the inner wall of the bottom side of the lathe 1. An annular heat dissipation pipe 10 is installed on the top of the water tank 8. The annular heat dissipation pipe 10 is sleeved on the outer wall of the mold base 7. When the machine works continuously, a micro water pump is installed on the inner wall of the water tank 8. The water pump will continuously inject water into the annular heat dissipation pipe 10 to cool the mold base 7. Positioning rods 4 are fixedly connected around the top side of the lathe 1. The top of the positioning rods 4 is fixedly connected to the top plate 2. The drive end of the cylinder 5 is connected to the movable plate 3. The inner wall of the movable plate 3 is slidably connected to the positioning rods 4. The positioning rods 4 are used for the movable plate 3 to move up and down and prevent the movable plate 3 from shifting.

[0021] Working principle: Specifically, during mold production, cylinder 5 on top plate 2 pushes the stamping block 6 on movable plate 3 closer to mold base 7 and into mold base 7. The sealing block at the end of stamping block 6 forms a sealed cavity inside mold base 7. Then, material enters the cavity from injection chamber 9 through injection hole on the bottom side of mold base 7. Water in water tank 8 is injected into annular heat dissipation pipe 10 by micro water pump to dissipate heat from mold base 7. After cooling, cylinder 13 drives ejector block 15 to eject the forming mold. When mold needs to be changed, motor 12 drives gear assembly 11 to operate. Bevel gear is installed on the drive end of motor 12. When starting, it drives the bevel gear on the rotating rod of gear assembly 11. The rotation causes the flat gears at both ends of the rotating rod to rotate. The flat gear at the top of the gear assembly 11 drives the gear ring 16 to rotate. Then, the gear ring 16 drives the limiting block 21 on the inner wall of the gear ring 16 to rotate away from the positioning groove of the positioning block 20 on the outer wall of the mold base 7, thereby unlocking the mold base 7. The flat gear at the bottom will drive the transmission gear to rotate. The transmission gear on the bottom side of the gear assembly 11 drives the gear ring 17 to rotate. Then, the fixing block 19 on the inner side of the gear ring 17 will rotate into the fixing hole of the connecting block 18, thereby fixing the connecting block 18. Thus, when the cylinder 2 13 drives the push rod 14, it drives the gear ring 17 to push out the mold base 7. Then, other models of mold base 7 can be installed into the lathe 1.

[0022] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
