[0001] The utility model relates to the technical field of carbon powder boxes for injection molding machines, in particular to a stirring frame connecting mechanism for a carbon powder box for an injection molding machine. Background Art

[0002] When performing injection molding, the injection molding machine usually uses a toner cartridge to blow carbon powder into the molded part. By adding carbon powder, the molded part can be colored on the one hand, and on the other hand, the carbon powder can increase the hardness of the molded part and improve the quality.

[0003] When the injection molding machine's toner cartridge is in use, a set of stirring racks will be set inside to continuously stir the internal toner to keep the toner in a loose state. Now, inside the toner cartridge, shaft seats are installed on both sides to support the stirring rack rotation. However, in actual installation, in order to prevent the stirring rack from falling off from the shaft seat, one end is usually plugged in, and the other end is inserted into the shaft seat after bending and deforming the stirring rack, so as to ensure a tight assembly and avoid falling off during later use. However, this also makes it troublesome to disassemble during later maintenance, and the stirring rack needs to be bent again. Multiple bending can easily cause the stirring rack to undergo rigid deformation or even break. For this reason, a special stirring rack connection mechanism for an injection molding machine toner cartridge is provided to solve the above problem. Utility Model Content

[0026] The embodiment of the present application provides a connecting mechanism for the stirring frame of the carbon powder cartridge of an injection molding machine, thereby solving the problem of the stirring frame inside the existing carbon powder cartridge. During actual installation, in order to prevent the stirring frame from falling off from the inside of the shaft seat, one end is usually inserted, and the other end is inserted into the shaft seat after the stirring frame is bent and deformed, thereby ensuring a tight assembly and preventing it from falling off during later use. However, this also makes it troublesome to disassemble during later maintenance, as the stirring frame needs to be bent again. Multiple bending can easily cause the stirring frame to undergo rigid deformation or even breakage.

[0027] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0028] The utility model embodiment discloses a connecting mechanism for a carbon powder box stirring frame of an injection molding machine.

[0029] According to the attached Figure 1-5As shown, it includes a stirring connecting shaft 21 and a stirring support 22 fixedly arranged at both ends of the stirring frame; the stirring support 22 includes a connecting sleeve 221, an assembly groove 222, an elastic fastener 223, a detachable latch 225 and a slot 227, the connecting sleeve 221 is integrally formed at the end of the stirring frame, the assembly groove 222 is opened inside the connecting sleeve 221, the detachable latch 225 is movably plugged into the inside of the assembly groove 222, the elastic fastener 223 is integrally formed on one side of the assembly groove 222, the slot 227 is opened on the side of the detachable latch 225, and the elastic fastener 223 is movably plugged into the inside of the slot 227.

[0030] In actual use, the detachable latch member 225 is inserted into the assembly groove 222 so that the end of the elastic fastener 223 is stuck in the groove 227 for fixation. When disassembling, the elastic fastener 223 is pulled out from the groove 227, and then the detachable latch member 225 is pushed deep into the assembly groove 222, so that the rotating column 228 is moved out from the rotating groove 131, thereby facilitating the disassembly and assembly of the stirring frame.

[0031] A positioning member 224 is fixedly provided on the inner side of the elastic fastener 223 , and a positioning slot 226 is provided on one side of the slot 227 . The positioning member 224 is movably inserted into the positioning slot 226 , so as to prevent the detachable latch member 225 from being deflected during installation.

[0032] Embodiment: A carbon powder box is arranged outside the stirring frame, and the cylindrical support members 11 and the rib fixing frame 13 at both ends of the inner wall of the carbon powder box are connected. The stirring connection shaft 21 is rotatably connected to the inside of the cylindrical support member 11, and a first row of powder grooves 12 are opened through the side of the cylindrical support member 11. When the stirring connection shaft 21 rotates inside the cylindrical support member 11 following the stirring frame, the cylindrical support member 11 supports the stirring connection shaft 21, and at the same time, the carbon powder entering the inside of the cylindrical support member 11 is discharged through the first row of powder grooves 12.

[0033] The detachable latch member 225 is rotatably connected to the inside of the rib fixing frame 13, and the outer end of the detachable latch member 225 is fixedly connected to a rotating column 228, and the rotating column 228 is movably inserted into the inside of the rib fixing frame 13. A rotating groove 131 is provided in the middle of the rib fixing frame 13, and the rotating column 228 is rotatably connected to the inside of the rotating groove 131. A strip powder discharge groove 132 is provided on the side of the rib fixing frame 13. The first powder discharge groove 12 and the strip powder discharge groove 132 are used to discharge carbon powder. When the rotating column 228 rotates inside the rotating groove 131 following the stirring frame, the rib fixing frame 13 supports the rotating column 228. At the same time, the strip powder discharge groove 132 is arranged to diverge in multiple directions. The carbon powder entering the inside of the rib fixing frame 13 is quickly discharged from the side, so as to avoid the problem of carbon powder being accumulated at the rotating connection, causing carbon powder to be squeezed and agglomerated, resulting in damage to the stirring frame.

[0034] Supporting parts 133 are disposed on both upper and lower sides of the rotating groove 131 . The supporting parts 133 are used to support the rotating column 228 , so as to improve the stability of the rotating column 228 when rotating in the rotating groove 131 .

[0035] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
