The specific embodiment
As shown in Figure 1, a kind of plastic hollow vessel processing method of the present invention comprises following preparatory stage and process segment:
Preparatory stage is made up of following operation: start operation 31, preparatory stage matched moulds, middle injection process 32, preparatory stage station die sinking operation 33.
Process segment is made up of following operation: the operation 34 of station conversion for the first time, for the first time matched moulds, middle injection process 35, station die sinking operation 36 for the first time, the operation 37 of station conversion for the second time, for the second time station matched moulds, middle injection, pressurize operation 38, station die sinking operation 39 for the second time.After station die sinking second time operation 39, enter first operation station conversion for the first time operation 34 operations in following one-period immediately.
Start operation 31, state is referring to Fig. 2, and the initial correspondence position of plug 7,8 can determine according to the actual needs that the initial position plug 7 of moving mold II is corresponding to the shaping station among the fixed mold I 4 in the present embodiment, and plug 8 is corresponding to injection station 5.Fixed mold I goes up left cylinder 1, right cylinder 2 makes shaping station 4,6 be in open state, and when plasticizing finishes, by installation forming station 4,6 cylinder operation, shaping station 4,6 resets.At this moment, the dynamic model in the moving mold II moves cylinder plug 7 is placed position, a left side.
Preparatory stage matched moulds, middle injection process 32, state are referring to Fig. 3, and close tightly with the cylinder 1,2 that shaping station 4,6 links to each other this moment, and forming cavity becomes one in the shaping station 4,6, by the steady locked mode of machine.Locked mode finishes, the plug 7 of the position, a left side among the moving mold II and the plug that is arranged in meta 8 lucky shaping station 4 and the injection station 5 that place fixed mold I respectively, machine begins to inject the high pressure melt to injection station 5, this melt can be produces the required high pressure melt of plastic hollow mould, to 8 pressurizes of plug in the injection station, make plug 8 have material base simultaneously.Realize that in this operation injection finishes operations such as pressurize.At this moment, plug 8 has material base, and plug 7 does not have material base.
Preparatory stage station die sinking operation 33, state are referring to Fig. 2, and the cylinder 1,2 that links to each other with shaping station 4,6 unclamps, and forming cavity opens in the shaping station 4,6, the machine die sinking, and shaping station 4, shaping station 6 are in open state.
Preparatory stage finishes the station conversion first time operation 34 that machine enters the process segment, this moment, working procedure states was referring to Fig. 4, dynamic model in the moving mold II moves cylinder 3 and moves the plug 8 that will have material base and place right position, there is not the plug 7 of material base to place meta, shaping station 4,6 resets, and realizes that in this operation shaping station 4 is to shaping station 6 conversions, if moulded products is arranged, will eject the moulded products that is attached on the plug 7 on this moment plug 7 by ejecting portable plate 13 machineries.
For the first time matched moulds, middle injection process 35, this moment working procedure states referring to Fig. 5, the machine matched moulds.At this moment, the cylinder 1,2 that links to each other with shaping station 4,6 closes tightly, makes shaping station 4,6 interior forming cavities become one, and the plug 8 that has material base is positioned at shaping station 6, does not have material base plug 7 to be positioned at injection station 5.Machine is pressurize after injection station 5 is injected pressurized melt on one side, makes to have material base on the plug 7; Inject the certain pressure gases by inflatable mouth 12 to shaping station 6 simultaneously, make that material base is blown into type on the plug 8.
Station die sinking operation 36 for the first time, this moment, working procedure states finished referring to Fig. 4, the cylinder that link to each other with shaping station 4,6 this moment unclamps, forming cavity in the shaping station 4,6 opens, the machine die sinking, the plug 7 that has material base leaves from middle injection station 5, and the plug 8 that has moulded products leaves in shaping station 6.
The operation 37 of station conversion for the second time, this moment, working procedure states was referring to Fig. 2, thereby moving drive plug 7,8 by mobile cylinder 3 in the moving mold II moves to left, there is the plug 8 of moulded products to be in the position of fixed mold I injection station 5 correspondences just after moving, there is the plug 7 of material base just to be in the position of shaping station 4 correspondences, eject portable plate 13 machinery from the plug 8 by machinery and eject moulded products this moment, do not have blank on the plug 8.
The station injection second time, air blowing, pressurize operation 38, this moment, working procedure states was referring to Fig. 3.Moulded products on plug 8 ejects and finishes, and the cylinder 1,2 that links to each other with shaping station 4,6 closes tightly, and forming cavity becomes one the machine matched moulds in the shaping station 4,6.At this moment, have the plug 7 of material base to be in shaping station 4 forming cavities, the plug 8 of no material base is in injection station 5 inside.Machine injects the high pressure melt to injection station 5 simultaneously, and pressurize, makes plug 7 have material base; Be blown into Continuous pressure-controlled air inflation by inflatable mouth 11 to the material base inside of shaping station 4 simultaneously, make material base inflation moulding on the plug 7.
Station die sinking operation 39 for the second time, and this moment, working procedure states was referring to Fig. 2, with shaping station 4,6 cylinders 1,2 that link to each other unclamp, and forming cavity opens in the shaping station 4, the machine die sinking has material base plug 8 and leaves from middle injection station 5, has on the plug 7 of moulded products to leave in shaping station 4.
And then enter first operation station conversion for the first time operation 34 in following one-period after station die sinking second time operation 39, shaping station 4 is opened the position, and plug 7,8 moves to right.At this moment, middle plug 7 has moulded products, and the right plug 8 has material base, and machine machinery ejects the goods on the plug 7.Goods eject and finish, and shaping station 6 resets, the machine matched moulds, and to injection station 5 high pressure melts, shaping station 6 begins to be blown into gases at high pressure simultaneously by barrel.Machine begins for the second time, and work begins circulation.If adopt the mould in a mould six chambeies, utilize this kind method article of manufacture, in a process-cycle, can produce 12 goods, improved production efficiency greatly, make the production cost of each relative goods reduce.
It is many to have overcome the production equipment that exists in the two step method processing method by this production method, the shortcoming that production link is too much.Adopt container in the processing plastic of the present invention, the automaticity and the production efficiency of production improve greatly.This production method is finished by a step from the parison to goods, makes whole process of production be in benign recurrent state simultaneously, finishes the moulding of air blowing and goods in the time of injection, and the effect that not only saves time is obvious, and the easier assurance of the quality of product.
