Description of the invention (5) It is formed by penetrating the guide die 14 at predetermined intervals. In this embodiment, the first, second, and third downflow channels 145 A, 145 B, and 145 C are formed. For example, the ratios of the relative diameters d1, d2, and d3 are from the center of the diversion mold 14 to the outside, and the proportions vary from small to large (the preferred embodiment of the present invention is that a plurality of diameters Small to large downflow channels 1 4 5) distributed outward from the center of the guide mold 14, if the volume of the largest diameter down flow channel 1 4 5 C is V 2, the volume V 2 is much smaller than VI and V 4; A cutting die 15 is a thin plate body corresponding to the guide die 14 and penetrates the cutting die 15 to form a cutout 1 5 1 corresponding to a plurality of downflow channels 1 4 5. The volume of the cutout 151 is It is determined as V3, and the volume V3 is approximately equal to V2. This is the micro-hot runner, runner and runner structure of the micro-injection module of the present invention. The preferred embodiment of the present invention is as follows (see Figures 2 and 4 to 6 for cooperation): First, the plastic injection device 13 is used to heat the injection material 1 31 to form a liquid, and then The injection raw material 1 3 1 flows into the runner 111 of the upper mold half 11 under pressure. The injection raw material 131 flows from the runner 111 into the upper mold 11 and then flows through the runner 111 into the feed recess 1 4 3 of the guide die 14 and from the feed recess 1 4 3 to the Plural branches of flow channels 1 4 4 flow away. At this point, the flow direction of the injection raw material 131 after flowing into the plurality of runners 144 is substantially the same as that flowing into the plurality of lower runners 1 4 5 among the first to third runners 145A to 145C. In this part, due to the downstream The diameters of the channels 145A to 145 C are outward from the center of the guide die 14 in a predetermined proportion from small to large, so the injection raw material 131 flows through the channel 14 4 to the first to second
第9頁 1229030 五、發明說明(6) 下流道1 4 5 A至1 4 5 C時,其流經的體積比例亦是相對由少 至多,藉由這樣射出原料1 3 1的流量體積的控制,可以在 大約相同的時間内,讓不論離該澆道1 1 1近或遠的模穴1 2 1 都流入大約相等的射出原料1 31。 這樣’該射出原料1 3 1在流過該複數個下流道1 4 5 A至 1 4 5 C後,乃相對流入該切斷模丨5的各切口丨5 1,並由各切 口151再流入該下半模12的模穴12ι,最後於該模穴12ι中 冷卻。 在該射出原料131冷卻為成品20的過程中,整個模組 中的溫度分佈,大約呈上半模丨丨最熱,以維持射出原料 1 3 1呈尚溫液狀、導流模丨4次熱,以讓射出原料丨3 1維持在 能被高壓擠動的濃稠狀、切斷模i 5次冷及下半模丨2最冷的 狀態。當成品20定型時,乃退去該切斷模15,這樣,在切 斷模1 5的退模過程,實際上是以該切斷模丨5的切口丨5 1, 直接而明確的將成品20自該模組中切割分離,如此,具有 加速成品2 0退模的效益。 、 更詳細的講,因該導流模上設有複數的流道,以及對 應該模穴的複數下流道。而在射出成型時,為使射出原料 能於流道與下流道間維持可被高壓擠動的濃稠狀,所以讓 。亥導流模(當然包括流道與下流道)保持基本的熱溫。_ 的範圍,故該下流道 穴之體積的設計,能 出原料減到最少的體 而流經該導流模之流 而因為模組大體是應用在微成型 (或流道)之體積遠小於該澆道與模 讓流經流道與下流道而尚未成型的射 積,以避免造成習用不必要的浪費。Page 9 1229030 V. Description of the invention (6) When the downflow channel 1 4 5 A to 1 4 5 C, the volume ratio flowing through it is also relatively small to at most, by controlling the flow volume of the raw material 1 3 1 thus ejected It is possible to let approximately equal injection materials 1 31 flow into the mold cavities 1 2 1 near or far from the runner 1 1 1 in about the same time. In this way, after the injection raw material 1 3 1 flows through the plurality of downflow channels 1 4 5 A to 1 4 5 C, it flows into the cutouts 5 1 of the cutting die 5 and flows into the cutouts 151 again. The cavity 12m of the lower mold half 12 is finally cooled in the cavity 12m. During the process of cooling the injection raw material 131 into the finished product 20, the temperature distribution in the entire module is approximately the upper half of the mold. It is the hottest to maintain the injection raw material 1 3 1 in a still-temperature liquid state and a diversion mold. 4 times Heat to keep the injection material 丨 3 1 in a thick state that can be squeezed by high pressure, the cutting mold i is cooled 5 times and the lower mold half 2 is the coldest state. When the finished product 20 is set, the cutting die 15 is retracted. In this way, during the ejection process of the cutting die 15, the cut 20 of the cutting die 丨 5 1 is actually used to directly and explicitly cut the finished product 20. It is cut and separated from the module. In this way, it has the benefit of speeding up 20 finished products. In more detail, the guide die is provided with a plurality of runners and a plurality of lower runners corresponding to the die cavity. During injection molding, in order to keep the injection raw material in a thick state that can be squeezed by high pressure between the flow channel and the down flow channel, let. The helium diversion die (including the runner and the runner, of course) maintains a basic thermal temperature. _ Range, so the design of the volume of the downflow channel can reduce the volume of raw materials to a minimum and flow through the guide mold. Because the module is generally used in microforming (or flow channel), the volume is much smaller than The runner and the mold allow the shot product flowing through the runner and the lower runner to be formed, so as to avoid unnecessary waste of usage.

Description of the invention (7) The injection raw material between the channel and the downflow channel will always be in a usable state that can be injection molded when forming the batch of finished products. This also improves the availability of the injection raw material in the module. To the highest. Of course, a cutting die is set under the diversion die, and a cutout corresponding to the downflow channel is provided through the cutting die. The cutout allows the injection material to flow into the cavity of the lower mold, and the finished product in the cavity After molding, as long as the sheet-shaped cutting mold is retracted from the position between the guide mold and the lower mold half, it is like cutting with a cutter between the finished product and the module, which is equivalent to synchronizing the finished product before the demoulding. Independent and complete molding reduces the cutting process of the finished product by one cutting step, which greatly reduces the industrial applicability. In particular, the volume of the cutout is equivalent to the volume of the downflow channel, so that the solidified injection product equivalent to the flow channel portion of the conventional module that has to be discarded can be minimized, and the production cost is effectively reduced. . And, the diameter of the plurality of downflow channels is sequentially predetermined from small to large from the center of the diversion die. Of course, the cutout is also in a corresponding state such that the volume and volume of the injected raw material are controlled. No matter it is the nearest or the farthest mold cavity, about the same amount of injection material can flow into the same time, which can improve the quality of the micro-injected product. Of course, in order to make the present invention more practical in application, the branch-shaped flow passage 144 and the plurality of lower flow passages 145 may be directly formed on the upper mold half n, or they may be separately formed on the upper mold half in a corresponding state. Between the die 丨 丨 and the diversion die 14, so that the invention can be elastically changed according to different application ranges. In addition, the division of the plurality of lower flow channels 145 on the branched flow channel 144
