Description

Technical Field

[0001] This utility model relates to the technical field of injection mold structure, specifically to an injection mold drying device. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of designs and shapes (from simple to complex), and sizes ranging from large to small. It also produces dimensionally accurate products, facilitates product updates and replacements, and can create complex shapes. Injection molding is suitable for mass production and molding processes involving complex shapes.

[0003] In the injection molding process, the molds used need to undergo cleaning and drying. Existing equipment, such as the injection mold drying device with patent publication number CN221881992U, uses a servo motor to drive a rotating rod and a placement cage to rotate, which flips the injection mold inside the cage, allowing water to be poured out from the mold gaps, thus greatly improving the drying rate. Furthermore, by incorporating an air inlet and exhaust pipe, the injection mold is placed in a sealed space, and a ventilation fan carries the heat generated by the electric heating rod into the drying chamber with the airflow, forming flowing hot air, thereby increasing the drying rate of the injection mold and reducing energy consumption.

[0004] However, the device's drying chamber is not effective in fixing the molds, making it impractical. Utility Model Content

[0022] 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. Example

[0023] Please see Figure 1-4A drying device for injection molds includes a water guide hopper 1, a connecting frame 2, a constraint ring 3, a rotating rod 4, a mesh basket 5, clamping screw sleeves 6, clamping screws 7, clamping handles 8, clamping contact pads 9, and a top cover 10. The upper middle part of the water guide hopper 1 is connected to the outer side of the constraint ring 3 via the connecting frame 2. The inner wall of the constraint ring 3 is rotatably connected to the outer wall of the middle part of the rotating rod 4. The top end of the rotating rod 4 is connected to the middle part of the bottom end of the mesh basket 5. The middle parts of the front and rear sides of the mesh basket 5 are respectively connected to the outer side of a set of clamping screw sleeves 6. The inner wall of each set of clamping screw sleeves 6 is screwed to the outer wall of a set of clamping screws 7. The outer side of each set of clamping screws 7 is respectively connected to the middle part of the inner side of a set of clamping handles 8. The middle and rear side of the top of the water guide hopper 1 is connected to the top cover via the clamping contact pad 9. The bottom rear side of the top cover 10 is movably connected, and a locking mechanism and a drying mechanism are provided between the water guide hopper 1 and the top cover 10. A driving mechanism is provided at the bottom of the water guide hopper 1. Before drying, the mold to be dried is placed inside the wire mesh basket 5. By turning the clamping handle 8, the corresponding clamping screw 7 is rotated. The clamping screw 7 is screwed into the clamping sleeve 6 and acts inward to clamp the outside of the mold. Then, the top cover 10 is closed under the constraint of the clamping contact pad 9 and is closed and fixed by the locking mechanism. Then, the driving mechanism acts on the rotating rod 4 to rotate under the constraint of the constraint ring 3, so that the wire mesh basket 5 rotates at high speed, centrifugally dewatering the mold. The water is discharged downward through the water guide hopper 1 after being blocked by the outside of the top cover 10, and is then dried on its surface by the drying mechanism.

[0024] The drying mechanism includes a connecting frame 11, a fan 12, an air duct 13, an air blowing hopper 14, and electric heating tubes 15. The rear middle side of the air blowing hopper 1 is connected to the front side of the fan 12 via the connecting frame 11. The output end of the fan 12 is connected to the input end of the air blowing hopper 14 via the air duct 13. The output end of the air blowing hopper 14 is connected to the top of the top cover 10, and multiple sets of electric heating tubes 15 are connected inside the air blowing hopper 14. The electric heating tubes 15 generate heat when energized, and can blow air through the fan 12. The air is transmitted to the output of the air blowing hopper 14 via the air duct 13, and the hot air is combined by the electric heating tubes 15 to dry the surface of the mold.

[0025] It also includes contact pads 16, with the inner side of each set of clamping screws 7 connected to the outer side of a set of contact pads 16 respectively; the contact pads 16 can make surface contact with the mold, increase static friction, avoid damage, and improve reliability.

[0026] The drive mechanism includes a drive motor 17, a reducer 18, a drive gear 19, and a driven gear 20. The bottom front end of the water guide hopper 1 is connected to the top end of the reducer 18. The output end of the drive motor 17 is connected to the input end of the reducer 18. The output end of the reducer 18 is connected to the middle of the bottom end of the drive gear 19. The bottom end of the rotating rod 4 is connected to the middle of the top end of the driven gear 20. The driven gear 20 and the drive gear 19 are in movable meshing. When the drive motor 17 runs, the reducer 18 can reduce the speed and drive the drive gear 19 to rotate. The drive gear 19 meshes with the driven gear 20, which in turn drives the rotating rod 4 to rotate.

[0027] It also includes a handle 21, a moving pin frame 22, and a fixed pin plate 23. The lower front side of the outer end of the top cover 10 is rotatably connected to the inner end of the handle 21. The output end of the handle 21 is connected to one side of the inner end of the moving pin frame 22. The upper front side of the inner top of the water guide hopper 1 is connected to the inner end of the fixed pin plate 23. When the top cover 10 is closed, the handle 21 can be turned to make the moving pin frame 22 rotate and insert into the fixed pin plate 23, so that the top cover 10 is closed and fixed, improving stability.

[0028] It also includes a sealing ring gasket 24, with the middle part of the top ring side of the water guide bucket 1 connected to the bottom end of the sealing ring gasket 24; the sealing ring gasket 24 can be used to close and seal the top cover 10, preventing water leakage and improving reliability.

[0029] In summary, when using an injection mold drying equipment, before drying, the mold to be dried is placed inside the wire mesh basket 5. Tightening the clamping handle 8 rotates the corresponding clamping screw 7, which, through its engagement with the clamping sleeve 6, clamps the mold inwards. The contact pad 16 allows for surface contact with the mold, increasing static friction and preventing damage. Then, the top cover 10 is closed under the constraint of the clamping contact pad 9. Tightening the handle 21 rotates the moving pin bracket 22, causing it to engage with the fixed pin 23, thus closing and fixing the top cover 10. The sealing ring gasket 24 allows for further drying. The top cover 10 is sealed to prevent water leakage. The drive motor 17 runs and can be reduced by the reducer 18 to drive the drive gear 19 to rotate. The drive gear 19 meshes with the driven gear 20, which drives the rotating rod 4 to rotate, causing the wire basket 5 to rotate at high speed. This centrifugal dewatering of the mold is achieved by the water being drained downwards through the water guide hopper 1 by the outer enclosure of the top cover 10. The electric heating tube 15 is energized and heats up, and the fan 12 blows air through the air guide duct 13 to the air blower 14. The hot air is generated by the electric heating tube 15 and acts on the surface of the mold to dry it.

[0030] The fan 12, heating element 15, drive motor 17 and reducer 18 are commercially available devices known to those skilled in the art. We are simply using them here without making any structural or functional improvements, and we will not elaborate further on them here.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
