Background technology
Rotation molding is the multi-purpose technique for manufacturing various hollow plastic parts, its be widely used in polyvinyl chloride plastic pellet,
The production of the small articles such as container.Its principle is to produce hollow single part using heating and along the rotation of two axis,
In the mould that the plastics injection of fusing is being rotated, centrifugal force forces the plastics of fusing to be attached on mould inner wall.By to mould
The heating of tool and vertical and horizontal rolling rotation, make material borrow self gravitation effect and centrifugal action to be equably covered with dies cavity
And melt, demolding after cooling and hollow product.
In traditional ball products production process, processing step is more, and most of process is required for workman's manual operations completion,
Labor intensity is high, low production efficiency, and because plastics can produce some pernicious gases, therefore working environment in process
Difference, is worked in above-mentioned working environment for a long time, and the healthy of workman can be impacted.
Rotational moulding streamline was occurred in that later, such as number of patent application 201320526902.X discloses a kind of full-automatic rotational moulding

Second short stroke drive mechanism locks linkage of unlocking principle with mould：
To convey one end where starting point station before on conveying direction between adjacent stations, where conveying terminal station
After one end is, i.e., before rotation-formed station is at one end, after commutation station of coming out of the stove is at one end；
As shown in Figure 10, the second driving seat 102 is changed from coming out of the stove in the horizontal direction under the driving of the second drive cylinder 101
Moved to station 5 to rotation-formed station 4；Second unidirectional pulling mobile limited block 103 is in the presence of the 3rd resetting-mechanism 105
Expose 102 upper surfaces of the second driving seat in top；Mold base 15 locks spacing in mould by exporting side mold lock and entrance side mold
The upper surface of block bracket 71；
As shown in Figure 11,12, the second unidirectional pulling mobile limited block 103 continues the mould receptacle to rotation-formed station 4
Frame 71 is moved,
The lower guiding surface 102a of second driving seat 102 first touches the unblock gangbar 134 of outlet die lock so that lock
Arm 131, latch hook 132 overcome the deformation power of hammerlock dynamic clamping head and quiet clamping head to be rotated around hammerlock bearing pin 135 so that latch hook 132 leaves mould
The rear side outer frame side of seat 15 is simultaneously less than the lower surface of mold base 15；
Afterwards, upper guiding surface 103a touches the rear side frame lower edge of the mold of mould block bracket 71 seat 15 so that the
The two unidirectional elastic deformation power for pulling mobile limited block 103 to overcome the 3rd resetting-mechanism 105, rotate around its bearing pin and are less than mould
The lower surface of seat；
As shown in figure 13, when the second unidirectional pulling mobile limited block 103 is continued to move to, it is passed to the rear side of mold base 15
Frame, now, the second unidirectional limitation for pulling mobile limited block 103 due to break away from moulds seat 15, it is in the 3rd resetting-mechanism 105
Under effect, rotated once more around its bearing pin and expose 102 upper surfaces of the second driving seat, and positioned at the rear side inframe side of mold base 15；
During this, by lower guiding surface 102a, push retaining surface push down always unblock gangbar 134；
As shown in figure 14, the second drive cylinder 101 driving second drives seat 102 in the horizontal direction from rotation-formed station 4
