Shown in Fig. 2,8,9, described link gear comprises oil cylinder connecting plate 41, interlock plate 42, interlock piece 43, bullet 44, big slide block fixed cover 45, outer fixed cover 46 and connecting plate 47.
Wherein oil cylinder connecting plate 41 pistons 11 direct and oil cylinder 1 are connected.
Described interlock plate 42 is two and spaced and parallel setting, and the afterbody of two interlock plates 42 is connected with the both sides of oil cylinder connecting plate 41 respectively, and the head of two interlock plates 42 is connected with the both sides of interlock piece 43 respectively.
Described bullet 44 is fixed together with interlock piece 43, and the tapered slope of bullet 44 is provided with the external chute 441 that cooperates with the spacing slide rail 321 in small slide block bottom, and in the present embodiment, external chute 441 is oat tail groove structure, and its structure as shown in Figure 4.
Described big slide block fixed cover 45 is arranged on outside large and small slide block 31,32 outside cores of forming 3, its structure as shown in Figure 5, big slide block fixed cover 45 is provided with spacing hole 451, spacing hole 451 flexibly connects with the stop screw 431 that is arranged on the interlock piece 43, simultaneously, be provided with somatotype guide pillar 452 between big slide block fixed cover 45 and the interlock piece 43, at this, rapid for guaranteeing both somatotypes, somatotype spring 453 is installed on the somatotype guide pillar 452.Big slide block fixed cover 45 endoporus are provided with the internal chute 454 that matches with the spacing slideway 312 of big slider top, and internal chute 454 is "T"-shaped groove in the present embodiment.
Described outer fixed cover 46 is wrapped in outside big slide block fixed cover 45, bullet 44 and the interlock piece 43, outer fixed cover 46 heads are provided with the reference column 461 that fastens with each big slider top locating slot 311, outer fixed cover 46 afterbodys are connected with the connecting plate 47 that passes gap, two interlock plates, 42 interval, has certain die sinking gap between connecting plate 67 and the interlock piece 43, connecting plate 47 centers arrange connecting rod 471, and connecting rod 471 passes bullet 44 and is connected with interior core 2 with the outside core 3 that large and small slide block forms.
The inner core pulling demoulding at seal groove of small pipe fitting of the present invention position is to realize like this, at first oil cylinder 1 action, oil cylinder piston 11 drives oil cylinder connecting plate 41, the interlock plate 42 that is attached thereto, interlock piece 43 and bullet 44 move synchronously, stop screw 431 heads on the interlock piece 43 go deep into the spacing hole 451 of big slide block fixed cover 45 gradually, at this moment, big slide block 31, big slide block fixed cover 45, connecting plate 47 and outer fixed cover 46 all keep motionless, interlock piece 43 is by somatotype guide pillar 452 and the somatotype spring 453 beginning somatotypes that are arranged on the guide pillar, the external chute 441 of the oat tail groove structure on spacing slide rail 321 relative bullets 44 inclined-planes, small slide block bottom glides, force small slide block 32 heads inwardly to make contractile motion, core barb up to small slide block 32 heads is deviate from from the seal groove of product fully, its structure as described in Figure 10, small slide block 32 is followed bullet 44 and is moved a segment distance after synchronously together subsequently, when finishing itself demoulding and for the demoulding of big slide block 31, prepare, staggered with the position of big slide block 31 in the position of small slide block 32, avoid both that mutual interference takes place.
When small slide block 32 moves to desired location, stop screw 431 deeply arrives the bottom of big slide block fixed cover spacing hole 451 and realizes the stop bit engaging, move after the continuation along with oil cylinder piston 11 subsequently, oil cylinder connecting plate 41, interlock plate 42, interlock piece 43, bullet 44, small slide block 32 and big slide block fixed cover 45 move synchronously, at this moment, connecting plate 47 and outer fixed cover 46 still keep motionless, and big slide block 31 top locating slot 311 with outside under the effect that engages of fixed cover reference column 461, the "T"-shaped spacing slideway 312 of big slider top moves relative to the "T"-shaped internal chute 454 of big slide block fixed cover endoporus 45, force big slide block 31 heads inwardly to make contractile motion, its structure as shown in figure 11.Core barb up to big slide block 31 heads is deviate from from the seal groove of product fully, at this moment, outer fixed cover reference column 461 breaks away from big slider top locating slot 311, big slide block 31 is with big slide block fixed cover 45 actions, move synchronously with small slide block 32, bullet 44, interlock piece 43, interlock plate 42 and oil cylinder connecting plate 41, this process is touched up to connecting plate 47 and interlock piece 43, finishes the demoulding of big slide block 31.
The piece 43 of then linking drives connecting plates 47 and moves after synchronously together, and the core 2 beginning demouldings under the effect of connecting plate connecting rod 471, driving, and also be synchronized with the movement with outer fixed cover 46 that connecting plate 47 is fixed together, arrive the extreme position of design up to oil cylinder piston 11, interior core 2 and outer fixed cover 46 break away from fully with product, so far, the inner core pulling demoulding at pipe fitting 6 seal groove positions 61 is finished, and its structure as shown in figure 12.
Eventually the above, the present invention designs for the inner core pulling demoulding at seal groove of small pipe fitting position specially, its dynamic mould core is divided into interior core 2, reaches the outside core of being made up of big slide block 31 and small slide block 32 3.When the demoulding, utilize cooperation and the transmission of each parts of link gear, move the demoulding after the interior contracting of realization small slide block 32 earlier, and then realize moving the demoulding after the interior contracting of big slide block 31, and the demoulding of the interior core 2 of realization in the end, this structure can effectively solve the inner core pulling release problems at pipe fitting sealing ring mounting groove position, has characteristics easy to use, high efficiency.
