This second module 12 comprises that 120, one of one second die holders are fixed on second die 121 on this first die holder 120 by retaining element (figure does not show).This second die 121 has one can be when matched moulds and above-mentioned first die joint, 112 contacted second die joints 122, offer four the 3rd grooves 123 that match with described first groove 113 and second connectivity slot 124 that matches with above-mentioned first connectivity slot 114 on this second die joint 122, these four the 3rd grooves 123 are interconnected by this second connectivity slot 124.This second module 12 also comprises an inlet 125 that runs through this second die holder 120 and this second die 121 and be connected with this second connectivity slot 124, by this inlet 125 injection material is injected formed die cavity between this first die 111 and this second die 121 behind this first module 11 and this second module, 12 matched moulds.
The grip unit 131 of this manipulator 13 is used for the stub bar that is positioned at described first connectivity slot 114 and separates with this second module 12 behind the clamping ejection molding and separating mould.These four suction nozzles 132 are corresponding respectively with four first grooves 113 of first die joint 112 of first module 11, and the arrangement mode of a plurality of die cavitys that form when also promptly the arrangement mode of these four suction nozzles 132 is with this first module 11 and second module, 12 matched moulds is corresponding.This injection part gatherer 14 has four and accommodates cave 141, accommodating cave 141 for these four is used to accommodate by the injection part of this first module 11 with these second module, 12 obtained by molding, these four to accommodate corresponding respectively i.e. these four arrangement mode and this four suction nozzle 132 arrangement modes of accommodating cave 141 of four suction nozzles 132 in cave 141 and this corresponding, accommodates in the cave 141 so that this manipulator 13 is inserted these four respectively with the injection part of obtained by molding.
This stub bar gatherer 15 in the present embodiment with these injection part gatherer 14 adjacent settings, it is used to accommodate described stub bar.
Below will briefly explain the course of work of this device for injection moulding 10:
During with this first module 11 and these second module, 12 matched moulds, four the 3rd grooves 123 on four first grooves 113 on first die joint 112 of described first die 111 and second die joint 122 of described second die 121 are over against forming four die cavitys, and described first connectivity slot 114 and second connectivity slot 124 are over against to form a runner.
When using above-mentioned device for injection moulding 10 to carry out moulding, injection material injects described runner, second groove 116 and four die cavitys via described inlet 125;
When this first module 11 and this second module 12 are carried out the branch mould, earlier the injection material in this runner, second groove 116 and four die cavitys is carried out cooled and solidified, and then first module 11 and second module 12 are separated from each other;
When carrying out the demoulding, drive this manipulator 13 move between this first module 11 and second module 12 and four suction nozzles 132 on this manipulator 13 relative with injection part in described four first grooves 113 respectively, and make the grip unit that is in open configuration 131 on this manipulator 13 relative with the stub bar that described inlet 125 places form;
Starting the vacuum generator that is connected with four suction nozzles 132 makes these four suction nozzles 132 be in adsorbed state, by described thimble 115 injection part in these four first grooves 113 is ejected then, four profiled members that are ejected are inhaled in the accepting hole 1321 of these four suction nozzles 132 by suction inlet 1322 respectively subsequently.At this, owing to can carry out particular design to the die cavity that forms behind the matched moulds and the cast gate of runner junction, for example that the shape very little, cast gate of cast gate design is consistent with the part at the edge that will form injection part etc., the profiled member that is beneficial to be ejected by thimble 115 does not need follow-up procedure for processing promptly to can be required injection part;
This grip unit 131 is adjusted into clamp position clamps with the stub bar that described inlet 125 places are formed, driving this manipulator 13 will be pulled out from this first module 11 by the stub bar that this grip unit 131 clamps;
Drive this manipulator 13 and will be placed the top of this stub bar gatherer 15, then this grip unit 131 is adjusted into open configuration so that stub bar falls into this stub bar gatherer 15 by the stub bar of these grip unit 131 clampings;
Drive this manipulator 13 with these four suction nozzles 132 move to this injection part gatherer 14 over against the position, and make these four suction nozzles 132 respectively with these four to accommodate cave 141 corresponding;
These four suction nozzles 132 are adjusted into releasing orientation,, accommodate cave 141 accordingly so injection part can fall into automatically because these four suction nozzles 132 are to be tilted to be installed on the support member 130.
Described device for injection moulding 10 utilizes suction nozzle 132 to take out the injection part in these four first grooves 113 behind the ejection formations and it is inserted respectively accommodate accordingly in the cave 141, can obtain the optical element finished product of automatic aperture separation, thereby shortened the production cycle of ejection formation optical element, and the cost of labor of producing the ejection formation optical element is decreased.
Be understandable that, the quantity of this first groove 113 and three groove 123 corresponding with it is not limited to four, can for two, more than three or four, if suction nozzle 132 on this manipulator 13 and the quantity of accommodating cave 141 on this injection part gatherer 14 are all identical with the quantity of this first groove 113 and this suction nozzle 132 and accommodate the arrangement mode in cave 141 and the arrangement mode of this first groove 113 corresponding.
In addition, first module 11 in the device for injection moulding of the present invention can be the cover half piece, and this second module 12 is the dynamic model piece simultaneously; This device for injection moulding can also be according to concrete needs, only are provided with groove forming die cavity behind the two matched moulds this first module 11 or second module, 12 1 sides, and are not limited to present embodiment.Those skilled in the art also can do other variation in spirit of the present invention, certainly, the variation that these are done according to spirit of the present invention all should be included within the present invention's scope required for protection.
