Injection molding liquid enters the casting groove 5012 during injection molding, and redundant injection molding liquid after injection molding is full flows into the residual liquid groove 5011 through the communication groove 5013, because injection molding is required to be full, if injection molding is not full, the thickness of a product is possibly disqualified, and after injection molding is finished, a water gap remains in a liquid inlet of the upper die 503.
After the injection molding is finished, the motor 412 continuously rotates to drive the connecting block 408 and the lower die 501 to advance, after the lower die 501 is separated from the stress bar 403, the lower die 501 descends relative to the connecting block 408 and returns to the initial position under the action of self gravity, when the inner prop 506 is in contact with the inner prop 405, the outer prop 507 is just in contact with the outer prop 404 at the moment, the connecting block 408 and the lower die 501 continuously advance, the inner prop 506 and the driving wheel 407 are jacked up through the inner prop 405 and the driving belt 406, so that the top sheet 502 is jacked up, and a product after the injection molding is jacked up through the top sheet 502, so that the product is separated from the casting groove 5012, and meanwhile, the upper die 503 is jacked up for a small distance along the sliding column 504, so that the heat dissipation and the rapid cooling of the product are facilitated at the moment.
When the connecting block 408 and the lower die 501 continue to advance, when the upper die 503 moves below the jack post 206, the belt motor 412 stops rotating, the bottom electric cylinder 415 stretches and drives the rear rack 421 to slide so as to drive the upper jack rack 424 to rise, the side top plate 505 and the upper die 503 are lifted up through the upper jack rack 424, the upper die 503 rises along the jack post 504, the upper die 503 is ejected with a water inlet hole of the upper die 503 through the cooperation of the jack post 206, at the moment, the upper die 503 and the lower die 503 are separated, and due to the existence of the water inlet of the product, the upper die 503 is bound with the upper die 503 through the water inlet hole, the upper die 503 needs to be ejected through the jack post 206, at the moment, the rotatable rotary column 401 and the object receiving plate 402 reach the front of the lower die 501 to take out the product, then the lower jack electric cylinder 202 stretches and drives the upper die 503 to descend along the jack post 504 so as to separate from the jack post 206, and then the belt motor 412 continues to advance, the lower die 501 and the lower die 408 is driven to advance through the jack post 408, and the lower die 503 moves into the bottom shell 1, at the moment, due to the gravity, the upper die 503 and the upper die 503 is separated from the upper die 503 and the lower die 501 is kept to be cooled conveniently.
That is, when the belt motor 412 rotates, the bottom cylinder 415 stops operating, and when the belt motor 412 stops rotating, the bottom cylinder 415 starts operating, and the mold release operation and the injection molding operation are performed simultaneously.
The invention discloses an injection molding device for a game machine shell, which comprises the following working principles: the plastic liquid is put in the material injection barrel 204, the conveying motor 208 rotates to drive the conveying rod 207 to rotate, the plastic liquid is conveyed in the material injection pipe 205 in a spiral manner, the plastic liquid is conveyed into the plastic discharge hopper 302, the motor wheel 413 is driven to rotate by the rotation of the motor 412, the transmission shaft 410 and the transmission wheel 407 are driven to rotate by the connecting belt 414, the transmission belt 406 and the connecting block 408 are driven to move, the lower die 501 is driven to move along with the movement of the transmission belt 406 and the connecting block 408, when the connecting block 408 and the lower die 501 move to contact with the stress bar 403, the stress bar 403 drives the lower die 501 to slide and rise relative to the connecting block 408, so that the lower die 501 is positioned on the stress bar 403 to prevent pressure from directly pressing on the driving belt 406, at the moment, when the upper die 503 is positioned below the plastic outlet bucket 302, the belt motor 412 stops rotating, the bottom electric cylinder 415 stretches to drive the bottom slide rod 416 to slide along the front swivel seat 418 and the rear swivel seat 422, so as to drive the front rack 417 to slide, so as to drive the front gear 419 to rotate, so as to drive the descending rack 420 and the inner slide rod 409 to descend along the outer sliding sleeve 425, thereby drive down clamp plate 303 to descend, can drive extrusion pole 304 to descend, because the elasticity of thick spring 305 is greater than the elasticity of thin spring 307, can promote charging basket 306 and go out to mould fill 302 at first and descend along barrel cover 310, go out to mould fill 302 and go out to contact with upper mould 503, and the liquid outlet is docked with the inlet of upper mould 503, thin spring 307 is compressed, extrusion pole 304 continues to descend afterwards, can drive interior push pedal 309 to descend, thick spring 305 is compressed, go out to mould fill 302 with mould liquid and press into between upper mould 503 and the lower mould 501 through interior push pedal 309 and carry out the operation of moulding plastics, pause for a short time after the completion of moulding plastics. Injection molding liquid enters the casting groove 5012 during injection molding, and redundant injection molding liquid after injection molding is full flows into the residual liquid groove 5011 through the communication groove 5013, because injection molding is required to be full, if injection molding is not full, the thickness of a product is possibly disqualified, and after injection molding is finished, a water gap remains in a liquid inlet of the upper die 503. After injection molding is completed, the motor 412 continues to rotate to drive the connecting block 408 and the lower die 501 to advance, after the lower die 501 is separated from the stress bar 403, the lower die 501 descends relative to the connecting block 408 and returns to the initial position under the action of self gravity, when the inner prop 506 is in contact with the inner prop 405, the outer prop 507 is just in contact with the outer prop 404 at this time, the connecting block 408 and the lower die 501 continue to advance, the inner prop 506 and the driving wheel 407 are jacked up through the inner prop 405 and the driving belt 406, so that the top sheet 502 is jacked up, and thus the injection molded product is jacked up through the top sheet 502, thereby disengaging the casting slot 5012 while lifting the upper die 503 a small distance along the slide post 504, which facilitates heat dissipation and rapid cooling of the product. When the connecting block 408 and the lower die 501 continue to advance, when the upper die 503 moves below the jack post 206, the belt motor 412 stops rotating, the bottom electric cylinder 415 stretches and drives the rear rack 421 to slide so as to drive the upper top rack 424 to lift up, the side top plate 505 and the upper die 503 are lifted up through the upper top rack 424, the upper die 503 lifts up along the sliding post 504, the upper die 503 is matched with the liquid inlet of the upper die 503 through the jack post 206, the upper product with a water gap is ejected out, at the moment, the upper die 503 and the lower die 501 are separated, the upper die 503 is adhered together through the liquid inlet due to the existence of the water gap of the upper product, the product is taken out by ejecting the product through the ejector pin 206, at this time, the rotatable rotating column 401 and the receiving plate 402 reach the front of the lower die 501, then the lower ejector cylinder 202 stretches to drive the upper die 503 to descend along the sliding column 504 so as to separate from the ejector pin 206, then the motor 412 is carried forward to drive the lower die 501 and the connecting block 408 to advance, and when the lower die 501 and the connecting block 408 move into the bottom shell 1, the upper die 503 slides along the sliding column 504 due to the gravity action of the upper die 503 and keeps separated from the lower die 501, so that the upper die 503 is convenient to cool. That is, when the belt motor 412 rotates, the bottom cylinder 415 stops operating, and when the belt motor 412 stops rotating, the bottom cylinder 415 starts operating, and the mold release operation and the injection molding operation are performed simultaneously. The whole injection molding and demolding process is continuously carried out.
