On base 41, on each work station right side and finish station right side and be provided with afterbody stopper seat 418, the afterbody stopper seat 418 that finishes station right side is provided with afterbody block 419.On base 41, between adjacent stations, be provided with leading truck 420, comprise the base plate that is connected with base 41, be arranged on base plate to the edge of work is played the riser of barrier effect and is arranged on the top board on riser.
Described stopping means can also be following structure: comprise the installing rack being arranged on base, installing rack 4151 is provided with limiting plate, on installing rack, on limiting plate right side, is hinged with baffle plate, is provided with and promotes the back-moving spring that baffle plate rotates to limiting plate between baffle plate and installing rack.
If while being processed with the injecting products of core, core can being arranged on to workpiece and pinching on seat 414; When if processing does not have the injecting products of core, workpiece pinches on seat 414 can arrange material taking piece, when the injection moulding of product main body, adopt part injected plastics material that material taking piece is coated and is connected with product main part, after carries product integral molded plastic completes, workpiece can be pinched to seat 414 and take off, then the material of covered section on product be removed and got product; If need to carry out injection molding on existing material, workpiece pinches on seat 414 and needs, according to material, corresponding clamping element is set.
During start, by manual control, required a plurality of workpiece are pinched to seat 414 and be positioned over each relevant position in connecting gear 4 and injection molding machine 1, then starting device enters automatic operating condition.While just starting, on each injection molding machine 1 of later process, there will be several injection moulding waste products, after the workpiece on the first injection molding machine 1 pinches seat 414 to complete first finished product of injection moulding output through each injection molding machine 1 successively, equipment just starts normal production.
When equipment turns round automatically, by a plurality of operation cycle, repeated injection molding.Wherein single operation cycle comprises:
Right driving oil cylinder 44 is retracted, making the left slider 410 of the close left locating piece 48 on each work station and right slide block 411 promote workpiece on these stations pinches seat 414 and moves right until left slider 410 props up right locating piece 49, now, each workpiece that each right slide block 411 promotes to be close to pinches seat 414 and props up respectively the left slider 410 of follow-up each work station and the afterbody block 419 that finishes station so that each workpiece at the most close follow-up each work station and end station place pinches seat 414;
Simultaneously, the left drive block 45 of left driving oil cylinder 43 piston 375 boom ends promotes workpiece and pinches seat 414 and move right and promote adjacent workpiece and pinch seat 414 from initial station, makes workpiece near the first work station place pinch seat 414 left slider 410 places that move to the first work station and completes location;
Meanwhile, the workpiece of end station is sent to initial station after pinching extracting jaw 4174 grippings of seat 414 by transfer bogie 417; The stripper apparatus that is arranged on initial station place pinches finished product on seat 414 by workpiece and takes off (as uneasy removable die device also can be by manually finishing station or initial station carries out stripping operation.In addition, stripper apparatus also can be arranged on and finish station place) so that pinching seat 414, workpiece can continue to recycle;
Then, wait for that each injection molding machine 1 injection moulding completes, patrix is opened;
Then, the workpiece that upper and lower fixture block 39 1 sides of pinch mechanism clamp on connecting gear 4 pinches seat 414, and the workpiece that opposite side clamps in injection machine pinches seat 414, and hoist cylinder 34 rises, and pusher oil cylinder 33 pulls pedestal 32 to retract, and rotary oil cylinder 37 rotates 180 °;
Then, right driving oil cylinder 44 stretches out, left slider 410 and right slide block 411 move to left locating piece 48 places, workpiece between two work stations pinches seat 414 and can be moved to the left, now the block 4153 of stopping means 415 can pinch in the spacing hole on seat 414 by embedding workpiece, in case workpiece pinches seat 414, returns a work station and produce interference under the effect of inertia;
Next step, pusher oil cylinder 33 is pushed pedestal 32 to injection molding machine 1 again, and hoist cylinder 34 is fallen, and clamping cylinder 36 unclamps, and two workpiece pinch 414 1 of seats and drop on injection moulding platform on a slide bar 47 that drops on conveyer;
Finally, injection molding machine 1 matched moulds carries out injection molding, enters next operation cycle simultaneously.
Like this, machining of a finished product needs through following several operation cycle: one, and workpiece clamping and conveying device 3 is from the initial station motor unit that moves right; Two, workpiece clamping and conveying device 3 moves to the first work station and is sent to the first injection molding machine 1 injection moulding; Three, workpiece clamping and conveying device 3 returns to the first work station; Four, workpiece clamping and conveying device 3 motor unit that continues to move right; Five, workpiece clamping and conveying device 3 moves to the second work station and delivers to the second injection molding machine 1; Six, workpiece clamping and conveying device 3 returns to the second work station, and seven, workpiece clamping and conveying device 3 moves to end station; Eight, transfer bogie 417 is sent initial station back to and is taken off injection-molded finished.
In this equipment each oil cylinder used also replaceable one-tenth can meet the cylinder of user demand, this technical scheme also, under this patent innovation and creation design, belongs to protection scope of the present invention.
