stock

31,32,32 ' of kenel such as molded first or second, and the difference that makes size between variant kenel stock mainly concentrates on the change of horizontal area, but not change as the thickness of known technology, thus, the stock of this kenel respectively is able to and the mould chamber locular wall of mould between have short distance, in the shaping mould chamber, flow equably in order to raw material, guarantee the quality of final molding product.

In addition, the applicant must be proposed to illustrate 3 points especially:

One, can change in the c step of method of moulding of germule size at this, the program that makes the volume of this stock mould chamber 28 be amplified to this first volume is not the genus necessary step, in detail, this step that is amplified to first volume is implemented, purpose only is to reduce macromolecule constitutive material suffered back pressure when material feeding, to reduce the required pressure of material feeding, and provide the darker degree of depth so that the macromolecule constitutive material that injects, be able to suitably be contained in the space of this stock mould chamber 28 major axis, one end, these steps have necessity of its existence when molded this first kenel stock 31, only belong to necessity in molded this second kenel stock 32 ' Shi Zefei, how much it mainly deciding on the injection material quantity.

They are two years old, back segment in this c step, the macromolecule constitutive material is injected in the space of corresponding stock mould chamber 28 major axis, one end, can be in molded this second kenel stock 32, in the time of 32 ', guarantee this second kenel stock 32, on 32 ' the locular wall direction corresponding to this stock mould chamber 28 major axis, one end and minor axis two ends, obtained to be given by this stock mould chamber 28 the setting effect of its shape, and the part that is formalized is existed only on the direction of holding in addition corresponding to these stock mould chamber 28 major axis, these conditions are for molded this first kenel stock 31, then non-genus is necessary, the condition that the macromolecule constitutive material is injected from corresponding stock mould chamber 28 major axis, one end only is best enforcement state, and not exclusive possible implementation.

Three, when this d step is implemented, the volume of this stock mould chamber 28 returns back to its original volume except making respectively in this volume adjustment part, it also must be looked actual demand and further the volume of stock mould chamber 28 is contracted on second volume less than this original volume, its:

One can be not only to have large, medium and small three kinds of sizes in response to final one-tenth shaped article size, that is the size variation of final molding product, therefore, see through the enforcement that stock mould chamber volume is contracted to second volume, can be with the macromolecule constitutive material of equivalent in the thickness growth and decline relative with the horizontal area intercropping, obtaining possible maximum horizontal area, thereby reduce the distance that raw material flows in the mould chamber of mould;

Other is the person, then can reach and give different compressions with the macromolecule constitutive material of equivalent, and make density different, act is with molded this first kenel stock 31, the volume that can further dwindle this stock mould chamber 28 in this d step so namely gets the thickness of this first kenel stock of minimizing to reach the effect that increases its density to this second volume;

Furthermore, for obtaining bigger horizontal area or the stock of different density, change the pressure that this fluid pressure cylinder spare 27 provides and obtain in implementing all can to see through, only the change of these pressure values is to need to change in response to actual demand, and its scope also has different numerical value demands in response to different mould kenels, can't general description, and importantly to those skilled in the art and need not can know via excessive experiment, be with, do not have the necessity specify its numerical value.
