Technique effect of the present invention is: through the design sealing block at the sprue two ends, make the demoulding easier.
The basic structure of injection mould all is made up of the fixed half and moving half two large divisions.Cover half partly is installed on the fixed head of injection machine, and dynamic model partly is installed on the movable plate of injection machine.During injection mo(u)lding, cover half partly and with hydraulically powered dynamic model part leads and closed through guide pillar, and plastic melt gets into the shape chamber from the injection machine nozzle through the die casting system; Injection mo(u)lding cooling back die sinking, promptly fixed half and moving half separates, and plastic is stayed on the dynamic model generally speaking, and the mould ejecting mechanism is with outside the plastic launch mode.
Effect according to each parts on the mould is different, and general injection mould can be made up of following components.
1. moulding parts
Specify the part of forming die cavity in mould, the dynamic model part.Usually form by core, die, mold insert etc., constitute die cavity during matched moulds, since the filled plastics melt, the shape and size of its decision plastic.
2. running gate system
Running gate system is that molten plastic gets into the passage that mold cavity is flowed through from the injection machine nozzle, and it is made up of sprue, runner cast gate and slag well.
3. guiding mechanism
Guiding mechanism is divided into two types of the guiding mechanisms of guiding mechanism and ejecting mechanism between dynamic model and the cover half.Head person is that assurance dynamic model and cover half are accurately involutory when matched moulds, to guarantee the accuracy of plastic shape and size; The latter avoids in the process of ejecting head board crooked and be provided with.
4. mould emptier
The device of when being used for die sinking plastic being deviate from from mould is claimed ejecting mechanism again.Its version is a lot, and common have push rod mould emptier, push pedal mould emptier and an ejector sleeve mould emptier etc.
5. undercut and core-pulling mechanism
When the side direction on the plastic had hole or the boss of concaveconvex shape, the punch or the core that just need side direction came moulding.Before plastic is released in die sinking, must be earlier side direction punch or side direction core be deviate from or extracted the smooth demoulding of plastic ability from plastic.The mechanism that side direction punch or side direction core are moved is called side core-drawing mechanism.
6. cooling system is put in heating
In order to satisfy the temperature requirement of Shooting Technique, must mold temperature be controlled, so mould usually is provided with cooling system and at mould inside or heating element heater is installed all around to mould.Cooling system is generally offered cooling water channel on mould.
7. gas extraction system
In injection molding process, for the air in the die cavity is discharged, usually need offer gas extraction system, normally autotelicly on die joint offer some grooves, or utilize the push rod of mould or the fit clearance between core and the template to carry out exhaust.The capacity of small plastic parts is little, therefore can directly utilize somatotype and exhaust, and needn't establish air discharge duct in addition.
8. other parts
As be used for fixing, support the moulding parts or play the parts etc. of location and position-limiting action.
Architectural feature according to injection mould is classified as follows mold:
1. single die joint injection mould
During die sinking, dynamic model and cover half separate, thereby take out plastic, claim single die joint mould, claim the double-plate mould again.It is the most basic the simplest a kind of form in the injection mold, and it can be designed to monotype chamber injection mould as required, also can be designed to many types of chamber injection mould, is most widely used a kind of injection mould.
2. two die joint injection moulds
Two die joint injection moulds have two die joints, compare with single die joint injection mold, and two die joint injection molds have partly increased by one at cover half can (be movable gate plate again by the local intermediate plate that moves; Which is provided with needed other part and assembly of cast gate, runner and cover half); So also be three-plate type (moving platen, intermediate plate, solid plate) injection mold; It is usually used in the monotype chamber of a cast gate charging or the injection mold in many types of chamber; During die sinking, intermediate plate separates as set a distance with solid plate on the guide pillar of cover half, coagulates material so that between these two templates, take out running gate system.Two die joint injection mould complex structures, manufacturing cost is higher, and the parts processing difficulties generally is not used in the moulding of large-scale or super-huge plastic products.
3. the injection mould that has undercut and core-pulling mechanism
When plastic has side opening or side recessed, need to adopt the core or the slide block moulding that can be displaced sideways.After the injection mo(u)lding, dynamic model at first moves down a segment distance, and the bevel phase that is fixed in the curved pin on the solid plate then forces slide block outwards to move, and the push piece of the push rod of mould emptier promotion meanwhile plate is taken off plastic on core.
4. the injection mould that has activity moulding parts
Because some special construction of plastic requires injection mould that mobilizable moulding parts are set, and like movable punch, movable matrix, movable insert, movable whorl core or type ring etc., when the demoulding, can outside plastic shifts out mould, separate with plastic then.
5. unload the screw thread injection mould automatically
To screwed plastic, when requiring automatic demoulding, the thread core or the type ring that can rotate can be set on mould; Utilize the rotating mechanism of die sinking action or injection machine; Or special transmission device is set, drive thread core or screw-type ring and rotate, thereby deviate from plastic.
6. there is not the runner injection mould
No runner injection mould is meant the method that employing is carried out adiabatic heating to runner, keeps being molten condition from the plastics between injection machine nozzle one die cavity, does not have running gate system when making die sinking take out plastic and coagulates material.The former claims the heat-insulating hot channel injection mould, and the latter claims HOT RUNNER INJECTION MOULD.
7. right-angle type injection mould
The right-angle type injection mold is only applicable to the angie type injection machine, and distinct with other injection moulds is that the direction of such mould charging when moulding is vertical with folding mould direction.His sprue is opened in both sides moving, the cover half die joint; And its sectional area is normally constant, and the mould that this and other injection machine is used is distinguishing, the end of sprue; In order to prevent the wearing and tearing and the distortion of injection machine nozzle and sprue entrance point, removable runner can be set insert.
8. the injection mould of mould emptier on cover half
In most of injection moulds, its stripper apparatus all is mounted in dynamic model one side, helps the work of liftout attachment in the injection machine folding modular system like this.In actual production, because some plastic receives the restriction of shape, it is more better to moulding that plastic is stayed cover half one side, this plastic is deviate from from mould, just must mould emptier be set in cover half one side.
Though the present invention discloses as above with preferred embodiment, the present invention is defined in this.Any those skilled in the art are not breaking away from the spirit and scope of the present invention, all can do various changes and modification, so protection scope of the present invention should be as the criterion with claim institute restricted portion.
