Description

Technical Field

[0001] This utility model relates to the field of injection molding technology, and in particular to an automatic unloading mechanism for injection molded parts processing. Background Technology

[0002] Injection molds are tools used to produce plastic products, and they also give plastic products a complete structure and precise dimensions. Specifically, they refer to the process of injecting molten plastic into the mold cavity under high pressure by an injection molding machine, and after cooling and solidification, a molded product is obtained. The product is then obtained by opening the mold and cooling it. They are widely used in modern industrial production.

[0003] Most injection molded parts are processed using injection molding. For injection molded parts formed in the injection molding machine, the injection molded parts can often only be pushed into the injection molding machine through the ejector pin in the middle of the injection molding machine. It is not possible to guide the injection molded parts inside the injection molding machine to the outside of the injection molding machine. Often, workers have to reach into the injection molding machine to pick them up, which is dangerous. In addition, the temperature of the injection molded product is high, and the surface of the injection molded part still has a certain temperature after demolding. If workers handle the injection molded part for a long time, it is easy to cause injury to their hands. Utility Model Content

[0004] The technical problem this invention aims to solve is that the temperature of the injection molded product is relatively high, and the surface of the injection molded part still has a certain temperature after demolding. If workers handle the injection molded part for a long time, it can easily cause damage to their hands.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an automatic unloading mechanism for injection molding parts, including a connecting table, a conveyor belt inside the connecting table, a first drive motor fixedly connected to the outer end of the connecting table, the output end of the first drive motor connected to the drive wheel of the conveyor belt, a connecting seat fixedly connected to the other outer end of the connecting table, and a connecting plate fixedly connected to the upper end of the connecting seat. By starting the first drive motor, the transmission belt can be driven to rotate, thereby automatically unloading and conveying the injection molding machine.

[0006] A cylinder is fixedly connected to the outer end of the connecting plate, and a push plate is provided through the extended end of the cylinder. A connecting frame is fixedly connected to the upper center of the connecting platform, and an air inlet box is provided through the upper end of the connecting frame. The cylinder pushes the demolded injection part in the injection molding machine body onto the conveyor belt, and the transmission belt discharges the injection part. The air inlet box can send cold air from the outside into the connecting frame to cool the injection part.

[0007] Preferably, a fixed frame is fixedly connected inside the air inlet box, and a second drive motor is fixedly connected to one end of the fixed frame. When the second drive motor is started, it drives the fan to rotate, sending cold air from the outside into the interior of the frame, thereby dissipating heat and cooling the injection molded parts on the conveyor belt.

[0008] Preferably, a fan is fixedly connected to the output end of the second drive motor, and an air inlet is provided inside the air inlet box.

[0009] Preferably, a dustproof mesh is installed inside the air inlet, and limit blocks are fixedly connected to both ends of the dustproof mesh. By setting a dustproof mesh and a vacuum cleaner at the outer end of the air inlet assembly, impurities can be prevented from adhering to the surface of the injection molded part during the cooling process, affecting its processing quality and improving the automatic feeding efficiency of the entire injection molded part.

[0010] Preferably, the air inlet has limit grooves at both ends, and the limit block corresponds to the limit groove.

[0011] Preferably, the outer end of the air inlet box has a slot, one end of the inner side of the slot is fixedly connected to a spring, the other end of the spring is fixedly connected to a limit plate, the other end of the limit plate is fixedly connected to a positioning block, the inside of the limit block has a positioning groove, and the positioning block corresponds to the positioning groove. By setting the limit block, the limit groove, the positioning block and the positioning groove, it is convenient for workers to disassemble and replace the dustproof mesh, thereby improving its dustproof effect. At the same time, the collection box can collect the cooled injection molded parts, realizing its automated unloading and collection operation.

[0012] Preferably, vacuum cleaners are provided at both ends of the connecting frame, and a collection box is provided at the other end of the connecting platform.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This utility model can automatically push injection molded parts onto a conveyor belt for conveying operations by setting a connecting seat, a cylinder and a push plate. By setting an air inlet box, a second drive motor and a fan in the middle of the conveyor belt, the injection molded parts can be cooled to reduce the surface temperature of the injection molded parts. Furthermore, by setting a dustproof mesh plate and a vacuum cleaner at the outer end of the air inlet assembly, impurities can be prevented from adhering to the surface of the injection molded parts during the cooling process, which would affect its processing quality and improve the automatic unloading efficiency of the entire injection molded parts.

[0015] 2. This utility model, by setting limit blocks, limit grooves, positioning blocks and positioning grooves, makes it convenient for workers to disassemble and replace the dustproof mesh, thereby improving its dustproof effect. At the same time, the collection box can collect the cooled injection molded parts, realizing its automated material unloading and collection operation. Attached Figure Description

[0023] Please see Figure 1 and Figure 2 An automatic unloading mechanism for injection molding parts includes a connecting platform 1, a conveyor belt 10 is provided inside the connecting platform 1, a first drive motor 11 is fixedly connected to the outer end of the connecting platform 1, the output end of the first drive motor 11 is connected to the drive wheel of the conveyor belt 10, and the first drive motor 11 can drive the conveyor belt 10 to rotate by starting the first drive motor 11, thereby automatically unloading and conveying the injection molding machine. A connecting seat 3 is fixedly connected to the other side of the connecting platform 1, and a connecting plate 4 is fixedly connected to the upper end of the connecting seat 3.

[0024] A cylinder 2 is fixedly connected to the outer end of the connecting plate 4. A push plate 5 is provided through the extended end of the cylinder 2. A connecting frame 9 is fixedly connected to the upper middle part of the connecting platform 1. An air inlet box 8 is provided through the upper end of the connecting frame 9. The cylinder 2 pushes the demolded injection part in the injection molding machine body onto the conveyor belt 10. The conveyor belt 10 discharges the injection part. The air inlet box 8 can send cold air from the outside into the connecting frame 9 to cool the injection part.

[0025] A fixed frame 20 is fixedly connected inside the air inlet box 8. A second drive motor 21 is fixedly connected to one end of the fixed frame 20. A fan 22 is fixedly connected to the output end of the second drive motor 21. An air inlet 13 is opened inside the air inlet box 8. When the second drive motor 21 starts, it drives the fan 22 to rotate, sending cold air from the outside into the interior of the connecting frame 9, thereby cooling the injection molded parts on the conveyor belt 10 and improving the heat dissipation effect of the entire device. In order to ensure that the injection molded parts can stay inside the connecting frame 9, infrared sensors are set at both ends of the connecting frame 9 to control the conveyor belt 10.

[0026] Please see Figure 3 , Figure 4 as well as Figure 5 The air inlet 13 is equipped with a dustproof mesh plate 7. The two ends of the dustproof mesh plate 7 are fixedly connected to limit blocks 15. Limit grooves 14 are opened at both ends of the air inlet 13. The limit blocks 15 correspond to the limit grooves 14. The outer end of the air inlet box 8 is provided with a slot 18. A spring 17 is fixedly connected to one end of the inner side of the slot 18. The other end of the spring 17 is fixedly connected to a limit plate 16. The other end of the limit plate 16 is fixedly connected to a positioning block 19. The limit block 15 is provided with a positioning groove 23. The positioning block 19 corresponds to the positioning groove 23. When the dustproof mesh plate 7 needs to be disassembled and replaced, the limit plate 16 is pulled outward. Under the action of the spring 17, the limit plate 16 can drive the positioning block 19 to retract inward. At this time, the positioning block 19 leaves the interior of the positioning groove 23. The staff can pull the dustproof mesh plate 7 upward to take it out and replace it, thereby improving the practicality and dustproof effect of the device.

[0027] Vacuum cleaners 6 are installed at both ends of the connecting frame 9, and a collection box 12 is installed at the other end of the connecting platform 1.

The first drive motor 11 starts to drive the conveyor belt 10 to operate, thereby conveying the injection molded part. When the part is conveyed to the bottom of the heat dissipation and cooling component, the conveyor belt 10 stops operating, and the internal second drive motor 21 starts to drive the fan 22 to rotate, sending cool air from the outside into the connecting frame 9, thereby dissipating and cooling the injection molded part on the conveyor belt 10 and improving the heat dissipation effect of the entire device. The vacuum cleaner 6 is activated to absorb the dust raised during the heat dissipation process of the injection molded part, preventing dust from polluting the environment. After a certain period of heat dissipation and cooling, the conveyor belt 10 starts again, which can convey the injection molded part to the collection box 12 for collection, improving the convenience and practicality of the device. The setting of the limiting block 15, limiting groove 14, positioning block 19 and positioning groove 23 makes it easy for the staff to disassemble and replace the dustproof mesh plate 7, improving its dustproof effect.
