DETAILED DESCRIPTION

[0031] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0032] The following describes an embodiment of the present invention based on its overall structure. Example

[0033] Please refer to the attached Figure 1 , 2 As shown in Figures 3, 4, 5 and 7, in a preferred embodiment of the present invention, a two-color injection molding system for producing laptop computer structural parts includes an injection molding mechanism, which is composed of a mobile frame 10, a drying barrel, an injection molding rod 11 and an injection molding screw 12. A mobile bin 13 is embedded in the injection molding screw 12, and a rectangular rod 131 is provided on the side wall of the mobile bin 13. A feed channel 132 is embedded in the rectangular rod 131. The input end of the feed channel 132 is connected to the bottom of the mobile groove 221 and fixed to the inner side wall of the injection molding rod 11. The feed channel 132 extends all the way to the outer bottom of the mobile frame 10. A feed pump 1321 is provided at the output end of the feed channel 132. The output end of the feed pump 1321 is connected to the waste storage mechanism through a pipeline.

[0034] It should be noted that, in this embodiment, when the injection molding machine is working, the injection molding material is first fed into the drying barrel through the feeding mechanism.

[0035] Please refer to the attached Figure 3 , 5As shown in FIG. 6 , in a preferred embodiment of the present invention, a rotating component 14 is embedded in the top of the mobile frame 10, and a meshing component 15 is provided at the execution end of the rotating component 14. The input end of the meshing component 15 is connected to the output end of the drying barrel. A blocking component 16 is embedded in the interior of the mobile frame 10, and a cleaning mechanism 20 is provided on the outer wall of the injection screw 12. The rotating component 14 includes a rotating motor 141 embedded in the top of the mobile frame 10, and a gear 142 is provided at the execution end of the rotating motor 141. The rotating motor 141 is electrically connected to the PLC controller, and the meshing component 15 includes a columnar frame 151 provided at the feeding port of the mobile frame 10. The inner wall of the column frame 151 is provided with a plurality of columns 152, and the plurality of columns 152 are threadedly arrayed on the inner wall of the column frame 151. The column frame 151 meshes with the gear 142. The blocking component 16 includes two slide grooves 161 embedded in the inner wall of the mobile frame 10. The two slide grooves 161 penetrate the inner wall of the mobile frame 10 and extend to the inner wall of the injection molding rod 11. The two slide grooves 161 are electrically connected to the blocking plate 162. The bottom structure of the blocking plate 162 is the same as the spiral structure of the injection molding screw 12. The blocking plate 162 divides the inner compartment of the injection molding rod 11 into zone a and zone b. The inside of the blocking plate 162 is provided with a temperature insulation plate.

[0036] It should be noted that, in the present embodiment, the drying barrel dries the injection molding material, and then conveys it after drying. When passing through the column frame 151, the rotating motor 141 is started to drive the gear 142 to rotate, and the gear 142 engages the column frame 151. At this time, the column frame 151 rotates to drive the internal column rod 152 to rotate to convey the injection molding material to prevent the material from being stuck during the conveyance, resulting in a decrease in the fusion efficiency. Then, the injection molding material enters the injection molding rod 11. At this time, the injection molding screw 12 is driven by the motor to convey the material to the injection molding end, and the heating mechanism is started to heat and melt the injection molding material in the injection molding rod 11. After the heating and melting are completed, the melted injection molding material is input into the mold. When new material enters the injection molding rod 11, the injection molding screw 12 is driven by the motor to convey the material to the injection molding end. The blocking plate 162 is driven by the motor to move in the slide groove 161, and the inner chamber of the injection rod 11 is divided into two areas a and b. The melted injection material is in area a, and the new material is in area b. At this time, the heating mechanism in area b is started to heat the new injection material, and the heat insulation plate inside the blocking plate 162 isolates the heat in area b to prevent the old injection material from being heated multiple times and carbonized and attached to the injection screw 12, resulting in carbonized material when the injection end is discharged. After the new injection material is heated, the blocking plate 162 returns to its original position to fuse the new material and the old material, so that the injection molding work continues. When the injection molding machine is completed, the electromagnetic block 211 is started to drive the moving block 212 to move on the outer wall of the injection screw 12.

[0037] Please refer to the attached Figure 7 , 8As shown in Figures 9, in a preferred embodiment of the present invention, the cleaning mechanism 20 includes a moving component 21 arranged inside the moving bin 13, and an opening and closing component 22 arranged on the outer wall of the injection molding screw 12. The moving component 21 includes an electromagnetic block 211 arranged on the inner wall of the injection molding rod 11. The electromagnetic block 211 moves on the inner wall of the injection molding rod 11 by simulating the thread path of the injection molding screw 12. The electromagnetic block 211 is magnetically connected to the moving block 212. The moving block 212 is arranged on the outer wall of the injection molding rod 11. A storage bin 2121 is embedded in the moving block 212. A plurality of slots are embedded at one end of the storage bin 2121. A discharge port is embedded at the bottom of the moving block 212. The discharge port is connected to the opening and closing plate through a rotating shaft. The opening and closing component 22 includes a moving groove 221 embedded in the outer wall of the injection molding rod 11, and the moving groove 221 is electrically connected to the opening and closing plate 222.

[0038] It should be noted that, in the present embodiment, the length of the electromagnetic block 211 is smaller than the length of the moving block 212, and the electromagnetic block 211 simulates the thread path of the injection molding screw 12 to drive the moving block 212 to clean the attachments on the surface of the injection molding screw 12. During the cleaning, the carbonized blocks will be filtered by the slots of the moving block 212, and the carbonized blocks will be stored in the storage bin 2121. When the cleaning is completed, the bottom of the moving block 212 is aligned with the top of the moving groove 221 and stops. At this time, the opening and closing plate 222 is driven by the motor to move to the inside of the moving groove 221, and then the moving The opening and closing plate at the bottom of the block 212 will open, and then the impurities inside the storage bin 2121 will fall into the feed channel 132. At this time, the extraction pump 1321 is started to extract the impurities inside the feed channel 132. After the extraction is completed, the moving block 212 is restored to its original position. Although the above-mentioned components can prevent carbonized materials from adhering to the injection screw 12, there will be residual materials adhering to the surface of the injection screw 12, which will hinder the subsequent melting and transmission of the injection material. By cleaning the moving block 212, the melting efficiency and utilization rate of the injection material can be improved.

[0039] The working principle of the present invention is:

[0040] The electrical components in the present invention are all triggered to operate by a PLC controller.

[0041] When the injection molding machine is working, the injection molding material is first fed into the drying barrel through the feeding mechanism, and the drying barrel dries the injection molding material. After drying, it is transmitted. When passing through the column frame 151, the rotating motor 141 is started to drive the gear 142 to rotate, and the gear 142 engages the column frame 151. At this time, the column frame 151 rotates to drive the internal column rod 152 to rotate to transmit the injection molding material to prevent the material from being stuck during transmission and causing the fusion efficiency to be reduced. Then, the injection molding material enters the injection molding rod 11. At this time, the injection molding screw 12 is driven by the motor to transmit the material to the injection molding end, and the heating mechanism is started to heat and melt the injection molding material in the injection molding rod 11. After the melting is completed, the melted injection molding material is input into the mold. When new material enters the injection molding rod 11, the blocking plate 162 is driven by the motor to move in the slide groove 161, and the inner chamber of the injection molding rod 11 is divided into two areas a and b. The melted injection molding material is in area a, and the new material entering is in area b. At this time, the heating mechanism in area b is started to heat the newly entered injection molding material, and the heat insulation plate inside the blocking plate 162 isolates the heat of area b to prevent the old injection molding material from being heated multiple times and carbonized and attached to the injection molding screw 12, resulting in carbonized material when the injection molding end is discharged. After the new injection molding material is heated, the blocking plate 162 returns to its original state. The electromagnetic block 211 is smaller than the length of the moving block 212, and the electromagnetic block 211 simulates the thread path of the injection molding screw 12 to drive the moving block 212 to clean the attachments on the surface of the injection molding screw 12. During the cleaning, the carbonized blocks will be filtered by the slots of the moving block 212, and the carbonized blocks will be stored in the storage bin 2121. After the cleaning is completed, the bottom of the moving block 212 is aligned with the top of the moving slot 221 and stops. At this time, the motor drives the start The closing plate 222 moves to the inside of the moving groove 221, and then the opening and closing plate at the bottom of the moving block 212 will open, and then the impurities inside the storage bin 2121 will fall into the inside of the feeding channel 132. At this time, the extraction pump 1321 is started to extract the impurities inside the feeding channel 132. After the extraction is completed, the moving block 212 is restored to its original position. Although the above-mentioned components can prevent carbonized materials from adhering to the injection molding screw 12, there will be residual materials adhering to the surface of the injection molding screw 12, which will hinder the subsequent melting and transmission of the injection molding material. By cleaning the moving block 212, the melting efficiency of the injection molding material and the utilization rate of the injection molding material can be improved.
