Description of drawings
Fig. 1 is the utility model upper reaches guidance tape sketch map;
Fig. 2 is the dirty guidance tape sketch map of the utility model.
The specific embodiment
Below, in conjunction with accompanying drawing the utility model is done further explanation.
Please refer to Fig. 1 and Fig. 2.A kind of flow passage structure of many material holes; Comprise a upper reaches guidance tape and in the face of the dirty guidance tape of said upper reaches guidance tape; Be provided with runner between said upper reaches guidance tape and the said dirty guidance tape, said runner is two " worker " fonts, and the middle part of said two " worker " font runner is communicated with through a sprue.

In the plastic process, die cavity mainly bears the pressure of plastic melt.Under the pressure effect of plastic melt, die cavity will produce internal stress and distortion.If die cavity wall thickness and base plate thickness are not enough, when the internal stress that produces in the die cavity surpassed the allowable stress of die cavity material, strength failure promptly took place in die cavity.Meanwhile, excessive strain then takes place in insufficient rigidity, thereby produces flash and influence plastic size and formed precision, also possibly cause demoulding difficulty etc.Therefore, be necessary to set up the computational methods of the science of die cavity strength and stiffness, especially to important, the demanding die cavity with large-scale plastic parts of precision of plastic can not be confirmed die sidewall and base plate thickness by rule of thumb, and should confirm through the calculating of strength and stiffness.
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.
