Description

Technical Field

[0001] The invention relates to the technical field of injection molding equipment, and in particular to an injection molding equipment for bag processing and production. Background Art

[0002] As we all know, trolley cases, as a kind of luggage, are deeply loved by people because of their large storage space and easy carrying. At present, the trolley cases on the market can be roughly divided into soft and hard types according to the materials used. The soft ones are made of cloth as raw materials, and the hard ones are made of plastic as raw materials by injection molding. The injection molding equipment for luggage processing and production is the auxiliary equipment used for injection molding of hard trolley cases.

[0003] After searching, the Chinese patent with publication number CN112406005A published on February 26, 2021 discloses an injection molding device for luggage processing and production, which is roughly described as including a bottom plate, a conveying mechanism, and a molding mechanism. A discharge box is provided at one end of the top of the bottom plate, and support rods are fixedly connected to the bottom of the discharge box on all sides. A discharge hopper is fixedly connected to one end of the top of the discharge box, and a discharge mechanism is provided inside the discharge box. A connecting box is fixedly connected to the bottom of the discharge box, and a discharge channel is drilled on the top of the inner wall of the connecting box. A mounting box is fixedly connected to one side of the connecting box. One side of the receiving box is fixedly connected with a conveying pipeline, a conveying mechanism is provided at the bottom of the unloading box, a molding mechanism is provided at the top end of the bottom plate away from the unloading box, an electric control box is fixedly installed on one side of the top of the bottom plate, and the molding mechanism includes mutually cooperating guide rails, side plates, connecting plates, rollers, mounting plates, fans, lower mold boxes, upper mold boxes, ventilation cooling pipes, air outlets, limit plates, U-shaped grooves, feed ports, servo motors, driven bevel gears, and active bevel gears. When in use, the equipment is first moved to the specified position, and then the equipment is powered on, and the plastic granule raw materials are moved from the unloading box to the unloading box through external equipment. The plastic particles are poured into the discharge box from the hopper, the discharge motor is turned on, and the plastic particles in the discharge box are stirred by the rotation of the stirring blade. The plastic particles fall from the discharge port, and continue to fall into the connection box after passing through the discharge channel. The conveying motor is turned on, and the auger piece is driven to rotate through the feed shaft to drive the plastic particles to move toward the molding mechanism. When the plastic particles pass through the heating pipe, the electric heating wire is turned on and the plastic particles are heated and melted by heat conduction. The liquid plastic passes through the bent pipe and is concentrated above the feed hopper. The valve of the solenoid valve is opened, and then the liquid plastic falls into the mold box. When the mold When the box is full of liquid plastic, close the solenoid valve and turn on the fan. Continuous cooling air flows through the ventilation cooling pipe and out of the air outlet, continuously cooling the mold box so that the liquid plastic can be quickly cooled and formed. After the plastic is formed, turn on the servo motor to drive the roller to rotate, so that the mold box moves along the guide rail to the side away from the conveying mechanism, then turn off the fan, open the upper mold box through the handle on one side of the upper mold box, take out the mold, and then reverse the servo motor to restore the mold box to its original position, and repeat the above operations to continue injection molding.

[0004] Although the above-mentioned prior art solution can be used for the injection molding of trolley cases, the structure of the lower mold box and the upper mold box is not clearly explained. There are various specifications and sizes of trolley cases on the market. People will choose trolley cases of appropriate specifications and sizes according to their use requirements. As for the above-mentioned upper mold box and lower mold box, it can be clearly seen from the accompanying drawings that the structure is relatively fixed, and it is not easy to adjust according to the specific specifications of the trolley case, and the flexibility of use is poor. At the same time, after the injection molding is completed, the structure formed by the lower mold box and the upper mold box will leave the feed hopper. Even if the solenoid valve forms a closure for the feed hopper, the liquid plastic outlet of the feed hopper will inevitably adhere to the liquid plastic. This part of the liquid plastic will be exposed to the outside. On the one hand, it will cool and harden, and on the other hand, it will inevitably fall due to the gravity of the liquid plastic itself. The hardened liquid plastic will inevitably affect the injection molding again, and the falling liquid plastic will inevitably cause material waste. Summary of the invention

[0040] The electric mold opening telescopic rod 17, servo motor 31 and stepper motor 49 in this embodiment are all conventional equipment purchased on the market and known to those skilled in the art, and can also be customized according to actual needs. In this patent, we only use them and do not improve their structure and function. For those skilled in the art, their setting method, installation method and electrical connection method only need to be debugged according to the requirements of their instruction manual, and they will not be described in detail here. The unloading mechanism 2 and the conveying mechanism 3 also adopt the corresponding structure in the Chinese patent with publication number CN112406005A proposed in the background technology. At the same time, other structures with similar functions can also be used. They are only used here, so their specific structures will not be described in detail.

[0041] In summary, the working process of the injection molding equipment for luggage processing and production is as follows: when in use, the injection molding equipment for luggage processing and production is first installed at the desired location, and the electric mold opening telescopic rod 17, the servo motor 31 and the stepping motor 49 are connected to the corresponding control circuit according to their respective instructions, and the operation is debugged. If necessary, the electric mold opening telescopic rod 17, the servo motor 31 and the stepping motor 49 can be equipped with a central controller to achieve the alternating or matching work of multiple electric mold opening telescopic rods 17, two servo motors 31 and one stepping motor 49. During operation, the central controller is first turned on to realize the coordinated work of the electric mold opening telescopic rod 17, the servo motor 31 and the stepper motor 49, and then the unloading mechanism 2 and the conveying mechanism 3 are turned on, and the plastic raw material is fed into the unloading mechanism 2. The plastic raw material is processed by the unloading mechanism 2 and the conveying mechanism 3 in sequence, and the liquid plastic after processing is squeezed into the guide tube 27 for use. A plurality of mold core assemblies pass directly below the guide tube 27 in sequence, and a plurality of mold shell assemblies are respectively arranged on the outside of the plurality of mold core assemblies, and the plurality of mold shell assemblies are respectively accompanied by the plurality of mold core assemblies. The two servo motors 31 work to drive the two rotating retracting cylinders 30 to rotate and fall, forming a connection with the injection cavity just below the feed pipe 27. During the connection process, when the two groove pipes 32 are rotated and adjusted to the vertical position, the mold shell assembly moves relative to the mold core assembly to form a mold clamping, realizing the formation of the injection cavity while also making the two The bevel tube 32 respectively enters into the space formed by the two first half-cylinders 13 and the space formed by the two second half-cylinders 15, so as to realize the connection between the feed tube 27 and the injection cavity. The conveying mechanism 3 works to inject liquid plastic into the injection cavity. After the injection and pressure holding are completed, the two servo motors 31 work again to realize the reverse rotation of the two rotating retractable cylinders 30, so that the two rotating retractable cylinders 30 are rotated and stored into the annular frame 5. Then the stepper motor 49 works to control the stepping movement of the annular frame 5, so as to form an injection molding for the plurality of injection cavities entering the bottom of the feed tube 27 in sequence.

[0042] Furthermore, during the injection molding process, a suitable position is selected as a mold opening and unloading station. When one of the multiple mold core assemblies and one of the multiple mold shell assemblies are moved to the mold opening and unloading station, the two electric mold opening telescopic rods 17 work to make the mold shell assembly located at the mold opening and unloading station move away from the mold core assembly inside it, so as to expose the injection-molded trolley case in the injection molding cavity of the mold opening and unloading station, and then manually unload the materials. After the unloading is completed, a mold core assembly and a mold shell assembly located at the mold opening and unloading station, accompanied by the rotation of the annular frame 5, sequentially enter the lower part of the guide tube 27 again to realize the injection molding process. The above steps are repeated in this way to realize the sequential production of multiple trolley cases. When the mold core assembly needs to be adjusted, the two driven screws 35 can be driven to rotate by rotating the drive column 40. The screw rod 35 is driven to rotate, so that the two telescopic cores 10 can move relative to the fixed mold core frame 7. During the synchronous adjustment of the two telescopic cores 10, the two end core frames 9 and the bridge core 11 will form a follow-up position adjustment. During the adjustment of the mold shell assembly, it is only necessary to rotate and loosen the first outer clamping bolt 23, the first inner clamping bolt 24, the second outer clamping bolt 25 and the second inner clamping bolt 26, and then adjust the positions of the first sliding shell 18, the second sliding shell 19, the first telescopic shell 20, the second telescopic shell 21 and the sealing shell 22 relative to the fixed shell 16. After the adjustment is completed, the first outer clamping bolt 23, the first inner clamping bolt 24, the second outer clamping bolt 25 and the second inner clamping bolt 26 are rotated in the opposite direction to fix the relative positions of the fixed shell 16, the first sliding shell 18, the second sliding shell 19, the first telescopic shell 20, the second telescopic shell 21 and the sealing shell 22.
