Based on the chair armrest injection molding system described in the first embodiment, a chair armrest injection molding method is provided, which comprises the following steps:
step 1: the gasket is subjected to vibration material selection through a vibration disc 21, and is vibrated onto a discharge channel 22; vibrating the gasket positioned on the discharging channel 22 to a discharging end through an electromagnetic vibrator 24 to wait for grabbing of the manipulator assembly 11;
step 2: starting a telescopic cylinder to drive a disc seat to rotate relative to the output end of the triaxial mobile frame, overturning until the side wall of the disc seat where the gasket sucking disc 113 group is located faces downwards, moving the gasket sucking disc 113 group to the upper part of the discharging channel 22 through the triaxial mobile frame, enabling the side wall of the disc seat to be parallel to the discharging end face, and enabling the gasket sucking disc 113 group to suck gaskets placed on the discharging end;
step 3: based on the direction that the gasket sucking disc 113 sets are arranged on the side wall surface of the disc seat, each gasket sucking disc 113 set is moved to the position right above the discharging end through the movement of the triaxial moving frame, and gaskets are sequentially sucked; each time a gasket is sucked from the discharge end, the next gasket is moved to the discharge end of the discharge channel 22 through the vibration of the electromagnetic vibrator 24, and after the gasket is completely covered on the surface of the discharge end, the electromagnetic vibrator 24 is closed;
Step 4: the manipulator assembly 11 is moved to the opening at the top of the injection molding machine through the triaxial moving frame, the telescopic cylinder is retracted, so that the tray seat reversely rotates to the initial position, at the moment, the tray seat and the output end of the triaxial moving frame are positioned on the same horizontal plane, and the material taking sucker 114 faces the movable mold core 44 and the gasket sucker 113 faces the fixed mold 42;
step 5: the mould in the injection molding machine is demolded, the movable mould 41 and the fixed mould 42 are separated, the manipulator assembly 11 stretches into the space between the movable mould 41 and the fixed mould 42 under the action of the output end of the triaxial movable frame, the gasket sucking disc 113 group moves towards the fixed mould cavity in the fixed mould 42, and the gasket is placed into a mounting column reserved in the fixed mould cavity; then, the movable mold core 44 is retracted, and simultaneously, the movable mold 41 moves towards the material taking sucking disc 114 under the drive of the second driving component, the material taking sucking disc 114 sucks the formed chair handrail positioned in the cavity of the movable mold, the movable mold core 44 is retracted to be flush with the surface of the movable mold 41, and the chair handrail is separated from the mold;
step 6: the material taking sucker 114 sucks the chair armrests, the chair armrests are moved onto the material discharging conveying mechanism 3 through the triaxial moving frame, the material taking sucker 114 stops operating and sucking, the chair armrests fall onto a conveying belt of the material discharging conveying mechanism 3, and the chair armrests are conveyed into the storage box through the conveying belt to be packaged.
The main innovation point of the chair armrest injection molding method described in the embodiment is that: firstly, the gasket is grabbed, placed into a die, sucked out from a chair armrest after injection molding, placed into a conveying track 32 for conveying and packaging, and scattered procedures are effectively integrated to form an optimized injection molding processing line, so that the working efficiency is greatly improved; secondly, the manipulator assembly 11 is switched back and forth among a gasket sucking mode, a gasket placing mode, a chair armrest sucking mode and a discharging mode through the rotation of the relative lifting arm 12, so that manpower is reduced, the productivity is improved, and the product is standardized due to the more refined operation.
Wherein, step 6 is further divided into two cases, wherein when only one first tray 112 is provided, the material taking sucker 114 and the gasket sucker 113 are respectively disposed on two opposite sidewalls of the first tray 112, and step 6 further includes: step 6.1: based on the sliding of the triaxial mobile frame, the manipulator assembly 11 and the chair armrests synchronously move to the discharging and conveying mechanism 3, at the moment, the horizontal plane where the chair armrests are positioned is at a certain obtuse angle with the surface of the conveying belt, and when the material taking sucker 114 stops operating and sucking, the chair armrests fall onto the surface of the conveying belt after turning over the angle relative to the conveying belt.
