The specific embodiment
Below, in conjunction with accompanying drawing the present invention is done further explanation.
Extremely shown in Figure 3 like Fig. 1; A kind of vehicle component mould comprises a upper impression mould and in the face of the lower impressions mould of said upper impression mould, the sprue that is provided with die cavity and is communicated with said die cavity between said upper impression mould and the said lower impressions mould; Said sprue also is communicated in a hand-hole; Be provided with four die cavity groups between said upper impression mould and the said lower impressions mould, said die cavity group comprises four die cavities, is provided with core in the said die cavity.Said hand-hole is positioned at said upper impression mould.
Further, said upper impression mould is provided with the first upper impression group, the second upper impression group, the 3rd upper impression group and the 4th upper impression group, and the said first upper impression group, the second upper impression group, the 3rd upper impression group and the 4th upper impression group are arranged in order.The said first upper impression group is made up of four die cavities, and the said second upper impression group is made up of four die cavities, and said the 3rd upper impression group is made up of four die cavities, and said the 4th upper impression group is made up of four die cavities.
Further, said lower impressions mould has the first lower impressions group, the second lower impressions group, the 3rd lower impressions group and the 4th lower impressions group, and the said first lower impressions group, the second lower impressions group, the 3rd lower impressions group and the 4th lower impressions group are arranged in order.The said first lower impressions group is made up of four die cavities, and the said second lower impressions group is made up of four die cavities, and said the 3rd lower impressions group is made up of four die cavities, and said the 4th lower impressions group is made up of four die cavities.
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.
