Description
本發明係關於一種模具及擾流結構,特別是一種設有擾流堆疊結構的模具及擾流堆疊結構。The invention relates to a mold and a spoiler structure, in particular to a mold provided with a spoiler stack structure and a spoiler stack structure.
目前塑膠射出光學透鏡或光學鏡片是在模具中利用上模仁及下模仁形成模穴。接著,在模穴中以高壓高溫方式注入熔融塑料,而在模穴形成所需的透鏡形狀。當光學透鏡或光學鏡片體積較大或厚度較厚時,代表注入的塑料量較多且累積較多熱量。最後,塑料在長時間冷卻固化後,即可將光學鏡片自上模仁或下模仁頂出,而得到所需的光學透鏡或光學鏡片。At present, plastic injection optical lenses or optical lenses use an upper mold core and a lower mold core to form a cavity in a mold. Next, molten plastic is injected into the cavity at a high pressure and high temperature, and a desired lens shape is formed in the cavity. When the optical lens or optical lens is larger or thicker, it means that more plastic is injected and more heat is accumulated. Finally, after the plastic is cooled and solidified for a long time, the optical lens can be ejected from the upper mold core or the lower mold core to obtain the required optical lens or optical lens.
目前光學鏡片之冷卻方式係在上模仁或下模仁設置散熱水路,以藉由散熱水路內之散熱流體來對模穴中的光學鏡片進行散熱。不過,目前散熱水路一般為直通式之設計,而既有直通式散熱水路,因傳統加工方式限制而不易靠近模穴進行冷卻。如此一來,將有可能導致處於高溫的光學成品與模具之間的溫差過大,進而讓光學鏡片有可能產生收縮率不一、翹曲與應力殘留等缺陷。此外,散熱流體於直通式散熱水路中受到較少的擾動,使得直通式散熱水路內之散熱流體往往因停留於模仁的時間較短而難以發揮出對光學鏡片的散熱效果。如此將拉長光學鏡片的冷卻時間,進而大幅降低光學鏡片的生產效率。At present, the cooling method of the optical lens is to set a heat dissipation water path in the upper mold core or the lower mold core to dissipate the optical lens in the mold cavity through the heat dissipation fluid in the heat dissipation water path. However, at present, the heat dissipation waterway is generally designed as a straight-through type, and the existing straight-through heat-dissipating waterway is not easily accessible for cooling due to the limitation of traditional processing methods. In this way, the temperature difference between the optical finished product and the mold at a high temperature may be too large, and then the optical lens may have defects such as uneven shrinkage, warpage, and residual stress. In addition, the heat-dissipating fluid is less disturbed in the straight-through heat-dissipating water path, so that the heat-dissipating fluid in the straight-through heat-dissipating water path often stays in the mold core for a short time, and it is difficult to exert the heat-dissipating effect on the optical lens. This will lengthen the cooling time of the optical lens, and then significantly reduce the production efficiency of the optical lens.
再者,目前既有的直通式散熱水路係直接對模具鑽孔或銑削加工而成,若要製造不同外形的光學鏡片時,則需對應不同光學鏡片的外形重新加工模具而形成專屬的直通式散熱水路。也就是說,在製造不同外形的光學鏡片時,需針對光學鏡片的外形重新提供具有專屬散熱水路設計的模具,進而增加模具與光學鏡片的製造成本。In addition, the existing straight-through heat-dissipating waterway system is directly drilled or milled into the mold. If optical lenses with different shapes are to be manufactured, the molds must be re-processed according to the shapes of the different optical lenses to form an exclusive straight-through Cooling waterway. In other words, when manufacturing optical lenses with different shapes, it is necessary to newly provide a mold with a dedicated heat dissipation waterway design for the shape of the optical lens, thereby increasing the manufacturing cost of the mold and the optical lens.
本發明在於提供一種模具及擾流堆疊結構,以解決透過既有模具製造光學鏡片時,散熱流體難以有效協助模仁散熱的問題及既有模具須為不同的光學鏡片重新加工出專屬的散熱水路,而增加光學成品製造成本之問題。The invention is to provide a mold and a turbulent stacking structure to solve the problem that when an optical lens is manufactured through an existing mold, it is difficult for the heat-dissipating fluid to effectively assist the mold core to dissipate heat, and the existing mold must re-process an exclusive heat dissipation channel for different optical lenses , And increase the manufacturing cost of optical products.
本發明之一實施例所揭露之一種模具,包含一母模仁以及一母擾流堆疊結構。母模仁具有一第一冷卻流道。母擾流堆疊結構位於第一冷卻流道中,且包含相互堆疊的多個母擾流板。至少二母擾流板各包含至少一第一分流件。其中,定義一基準面。基準面的法線方向平行於母擾流堆疊結構的一堆疊方向。二第一分流件於基準面上的投影不完全重疊,而令母擾流板共同形成一第一擾流道。A mold disclosed in an embodiment of the present invention includes a female mold core and a female spoiler stack structure. The female mold core has a first cooling runner. The mother spoiler stack structure is located in the first cooling flow channel and includes a plurality of mother spoilers stacked on each other. Each of the at least two mother spoilers includes at least one first shunt. Among them, a datum is defined. The normal direction of the reference plane is parallel to a stacking direction of the mother spoiler stacking structure. The projections of the two first shunts on the reference plane do not completely overlap, so that the mother spoiler forms a first spoiler together.
本發明另一實施例所揭露之擾流堆疊結構,適於位於一冷卻流道中。擾流堆疊結構包含多個擾流板。擾流板相互堆疊。至少二擾流板各包含至少一第一分流件。定義一基準面。基準面的法線方向平行於擾流堆疊結構的一堆疊方向。二第一分流件於基準面上的投影不完全重疊,而令擾流板共同形成一擾流道。The spoiler stack structure disclosed in another embodiment of the present invention is suitable for being located in a cooling flow channel. The spoiler stack structure includes multiple spoilers. The spoilers are stacked on top of each other. Each of the at least two spoilers includes at least one first diverter. Define a datum. The normal direction of the reference plane is parallel to a stacking direction of the spoiler stack structure. The projections of the two first shunts on the reference plane do not completely overlap, so that the spoiler forms a spoiler together.
根據上述實施例所揭露的模具及擾流堆疊結構,由於擾流堆疊結構位於冷卻流道中,且擾流堆疊結構之至少二第一分流件於基準面上的投影不完全重疊。因此,當散熱流體通過冷卻流道時,便會於擾流道中形成紊流,而延長散熱流體停留於擾流堆疊結構中的時間。如此一來,便能增加與擾流堆疊結構的熱交換效率,而提升散熱流體之散熱效果。另一方面,當擾流堆疊結構位於母模仁的第一冷卻流道中而為母擾流堆疊結構時,不完全重疊的至少二第一分流件便能使散熱流體於第一擾流道中形成紊流,進而提升散熱流體協助母模仁散熱的效果。According to the mold and the spoiler stack structure disclosed in the above embodiments, since the spoiler stack structure is located in the cooling runner, and the projections of at least two first shunt members of the spoiler stack structure on the reference plane do not completely overlap. Therefore, when the heat dissipation fluid passes through the cooling flow channel, turbulence is formed in the spoiler channel, and the time for the heat dissipation fluid to stay in the spoiler stack structure is prolonged. In this way, the heat exchange efficiency with the turbulent stack structure can be increased, and the heat dissipation effect of the heat dissipation fluid can be improved. On the other hand, when the spoiler stack structure is located in the first cooling flow channel of the female mold core and is a mother spoiler stack structure, at least two first shunts that are not completely overlapped can form a heat dissipation fluid in the first spoiler channel. The turbulence improves the effect of the heat-dissipating fluid to assist the female mold core to dissipate heat.
此外,由於第一擾流道係由這些母擾流板所拼湊而成。因此,使用者能依照不同光學成品的溫度分佈重新排列母擾流板,而拼湊出對應不同溫度分佈的第一擾流道。如此一來,便無需藉由重新切削的方式提供具有專屬冷卻流道設計的模具,而降低製造光學成品的成本。In addition, since the first spoiler is made up of these mother spoilers. Therefore, the user can rearrange the mother spoiler according to the temperature distribution of different optical products, and piece together the first spoiler corresponding to the different temperature distribution. In this way, there is no need to provide a mold with a dedicated cooling runner design by re-cutting, thereby reducing the cost of manufacturing the optical finished product.
以上關於本發明內容的說明及以下實施方式的說明係用以示範與解釋本發明的原理,並且提供本發明的專利申請範圍更進一步的解釋。The above description of the content of the present invention and the description of the following embodiments are used to demonstrate and explain the principle of the present invention, and provide further explanation of the scope of the patent application of the present invention.
請參閱圖1至圖2。圖1為根據本發明第一實施例之模具的立體圖。圖2為圖1之模具的剖面示意圖。Please refer to Figures 1-2. FIG. 1 is a perspective view of a mold according to a first embodiment of the present invention. FIG. 2 is a schematic cross-sectional view of the mold of FIG. 1.
本實施例之模具10例如用以製造光學成品15且包含一母模仁20、一公模仁30、多個冷卻管40、一母擾流堆疊結構50及一公擾流堆疊結構60。The mold 10 of this embodiment is used to manufacture an optical finished product 15 and includes a female mold core 20, a male mold core 30, a plurality of cooling pipes 40, a female turbulent stacking structure 50, and a public turbulent stacking structure 60.
母模仁20具有一第一冷卻流道21。公模仁30設置於母模仁20的一側,且具有一第二冷卻流道31。這些冷卻管40例如分別設置於母模仁20及公模仁30而分別連接於第一冷卻流道21以及第二冷卻流道31,進而用以導引一散熱流體(未繪示)至第一冷卻流道21及第二冷卻流道31內。The female mold core 20 has a first cooling flow passage 21. The male mold core 30 is disposed on one side of the female mold core 20 and has a second cooling channel 31. These cooling pipes 40 are respectively disposed on the female mold core 20 and the male mold core 30, and are respectively connected to the first cooling flow passage 21 and the second cooling flow passage 31, and are further used to guide a heat dissipation fluid (not shown) to the first Inside a cooling flow passage 21 and a second cooling flow passage 31.
請參閱圖2至圖5。圖3為圖1之母擾流堆疊結構的立體圖,其外形為四方形。圖4為圖3之母擾流堆疊結構的分解示意圖。圖5為圖3之母擾流堆疊結構的其中二母擾流板的立體示意圖。See Figures 2 to 5. FIG. 3 is a perspective view of the mother spoiler stack structure of FIG. 1, which has a square shape. FIG. 4 is an exploded view of the mother spoiler stack structure of FIG. 3. 5 is a schematic perspective view of two mother spoilers in the mother spoiler stack structure of FIG. 3.
母擾流堆疊結構50位於第一冷卻流道21中,且包含多個母擾流板。這些母擾流板即分別為圖4中之各片具鏤空結構的板材。這些母擾流板沿一堆疊方向A相互堆疊,且例如以擴散焊接相互固定。相互固定的母擾流板具有一流入面5000、一流出面5001以及一環形側面5002。流入面5000背對於流出面5001。環形側面5002介於流入面5000以及流出面5001之間。The mother spoiler stack structure 50 is located in the first cooling flow passage 21 and includes a plurality of mother spoilers. These mother spoilers are the plates with hollow structures in FIG. 4 respectively. These mother spoilers are stacked on each other in a stacking direction A, and are fixed to each other, for example, by diffusion welding. The fixed mother spoiler has an inflow surface 5000, a first outlet surface 5001, and an annular side surface 5002. The inflow surface 5000 faces away from the outflow surface 5001. The annular side surface 5002 is interposed between the inflow surface 5000 and the outflow surface 5001.
由於這些母擾流板的外形變化繁多,因此僅針對部分母擾流板進行說明。這些母擾流板之部分包含一第一母擾流板501、一第二母擾流板502及二分區隔流板503。Because the shapes of these mother spoilers vary widely, only part of the mother spoilers will be described. Part of these mother spoilers includes a first mother spoiler 501, a second mother spoiler 502, and a two-zone spoiler 503.
如圖4所示,第一母擾流板501包含二側邊條5010、一頂邊條5011、一底邊條5012、多個第一分流件5013及多個第二分流件5014。頂邊條5011、底邊條5012、這些第一分流件5013及這些第二分流件5014介於二側邊條5010之間。詳細來說,頂邊條5011的相對兩側分別連接於二側邊條5010,且底邊條5012的相對兩側分別連接於二側邊條5010。因此,二側邊條5010、頂邊條5011及底邊條5012例如呈現口形的外觀。這些第一分流件5013及這些第二分流件5014例如相互垂直與相交。每一第一分流件5013的相對兩側分別連接於二側邊條5010,且每一第二分流件5014的相對兩側分別連接於頂邊條5011及底邊條5012。As shown in FIG. 4, the first mother spoiler 501 includes two side strips 5010, a top edge strip 5011, a bottom edge strip 5012, a plurality of first shunts 5013, and a plurality of second shunts 5014. The top edge strip 5011, the bottom edge strip 5012, the first diverter pieces 5013, and the second diverter pieces 5014 are interposed between the two side strip pieces 5010. In detail, the opposite sides of the top edge strip 5011 are respectively connected to the two side edges 5010, and the opposite sides of the bottom edge strip 5012 are respectively connected to the two side edges 5010. Therefore, the two side strips 5010, the top strip 5011, and the bottom strip 5012 have, for example, a mouth-shaped appearance. The first shunts 5013 and the second shunts 5014 intersect with each other, for example. Opposite sides of each first diverter 5013 are connected to two side strips 5010, and opposite sides of each second diverter 5014 are connected to a top side strip 5011 and a bottom side strip 5012, respectively.
第二母擾流板502包含二側邊條5020、多個第一分流件5021及多個第二分流件5022。這些第一分流件5021及這些第二分流件5022介於二側邊條5020之間。詳細來說,這些第一分流件5021及這些第二分流件5022例如彼此垂直與相交,且每一第一分流件5021的相對兩側分別連接於二側邊條5020。The second mother spoiler 502 includes two side bars 5020, a plurality of first shunts 5021, and a plurality of second shunts 5022. The first diverter pieces 5021 and the second diverter pieces 5022 are located between the two side strips 5020. In detail, the first shunts 5021 and the second shunts 5022 are, for example, perpendicular to and intersect with each other, and opposite sides of each first shunt 5021 are respectively connected to two side strips 5020.
本發明並不以第一母擾流板501及第二母擾流板502的結構為限,於其他實施例中,第一母擾流板或第二母擾流板的結構亦可依據實際需求而改變。詳細來說,於其他實施例中,這些第一分流件及這些第二分流件之間亦可夾一銳角、於其他實施例中,這些母擾流板中亦可僅有第一母擾流板及第二母擾流板各包含一個第一分流件,且僅有第一母擾流板及第二母擾流板各包含一個第二分流件,或者於其他實施例中,第一母擾流板及第二母擾流板亦可無須包含第二分流件而僅包含第一分流件。The present invention is not limited to the structures of the first mother spoiler 501 and the second mother spoiler 502. In other embodiments, the structure of the first mother spoiler or the second mother spoiler may also be based on actual conditions. Demand changes. In detail, in other embodiments, an acute angle may be included between the first shunts and the second shunts. In other embodiments, the mother spoiler may have only the first mother spoiler. The plate and the second mother spoiler each include a first shunt, and only the first mother spoiler and the second mother spoiler each include a second shunt, or in other embodiments, the first mother The spoiler and the second mother spoiler may also include the first diverter without including the second diverter.
另外,二分區隔流板503可設置於第一母擾流板501之前端。舉例來說,流入面5000位於外側的分區隔流板503上,且外側的分區隔流板503的第二分流件5031將流入面5000分隔成一中央區域B1及二側區域B2、B3。中央區域B1介於二側區域B2、B3之間,且中央區域B1之面積較二側區域B2、B3各自的面積大。而其餘之母擾流板各具有位置上分別對應分區隔流板503之中央區域B1及二側區域B2、B3的一中央區域B1及二側區域B2、B3。如此一來,光學成品之中央厚度較大的區域便能因各個中央區域B1具有較大的面積,而流通有更多的散熱流體,進而增加散熱流體之散熱量。In addition, the two-zone baffle plate 503 may be disposed at the front end of the first mother spoiler 501. For example, the inflow surface 5000 is located on the outer partition baffle 503, and the second diverter 5031 of the outer partition baffle 503 separates the inflow surface 5000 into a central area B1 and two side areas B2 and B3. The central region B1 is located between the two-sided regions B2 and B3, and the area of the central region B1 is larger than the area of each of the two-sided regions B2 and B3. The other mother spoilers each have a central region B1 and two-sided regions B2 and B3 corresponding to the central region B1 and the two-sided regions B2 and B3 of the partitioned baffle 503 respectively. In this way, a region with a large central thickness of the optical finished product can circulate more heat-dissipating fluid because each central region B1 has a larger area, thereby increasing the amount of heat-dissipating fluid.
如圖5所示,定義一基準面S以說明第一及第二母擾流板501、502的重疊關係。基準面S的法線方向N平行於堆疊方向A。這些第一分流件5013於基準面S上的投影P1及這些第一分流件5021於基準面S上的投影P2(繪示有斑點的部分)實質上不完全重疊。本實施例中,投影的實質上不完全重疊包含較小的投影位於較大的投影之範圍內、其中一投影部分位於另一投影的範圍中,及其中一投影不位於另一投影的範圍中。藉此透過這些第一分流件5013、5021令第一及第二母擾流板501、502共同形成一第一擾流道5003(如圖2所示)之局部。第一擾流道5003(如圖2所示)其餘之部分以類似的方式形成故不再贅述。如圖2所示,第一擾流道5003的相對兩側分別連通於流入面5000以及流出面5001。As shown in FIG. 5, a reference plane S is defined to explain the overlapping relationship between the first and second mother spoilers 501 and 502. The normal direction N of the reference plane S is parallel to the stacking direction A. The projections P1 of the first shunts 5013 on the reference plane S and the projections P2 of the first shunts 5021 on the reference plane S (parts with spots shown) do not substantially overlap. In this embodiment, the substantially incomplete overlap of the projections includes that the smaller projections are located in the range of the larger projections, one of the projections is located in the range of the other projection, and one of the projections is not in the range of the other projection. . This allows the first and second mother spoilers 501 and 502 to form a part of a first spoiler 5003 (as shown in FIG. 2) through these first shunts 5013 and 5021. The rest of the first spoiler 5003 (shown in FIG. 2) is formed in a similar manner, so it will not be described again. As shown in FIG. 2, opposite sides of the first spoiler 5003 are communicated with the inflow surface 5000 and the outflow surface 5001, respectively.
當散熱流體於第一擾流道5003中流經第一母擾流板501時,散熱流體會受到這些第一分流件5013的阻擋而分流。接著當散熱流體由第一母擾流板501流至第二母擾流板502時,散熱流體便會受第一分流件5021的阻擋而分流。而由於第一母擾流板501的第一分流件5013與第二母擾流板502的第一分流件5021不完全重疊,使得散熱流體在不同位置上分別受第一分流件5013及第一分流件5021阻擋而分流,進而使散熱流體於第一擾流道5003中受到強烈的擾動並形成紊流。如此一來,便能延長散熱流體於第一擾流道5003中所停留的時間,藉以提高散熱流體的熱交換效率。When the heat-dissipating fluid flows through the first mother spoiler 501 in the first spoiler 5003, the heat-dissipating fluid will be blocked by these first flow-dividing members 5013 to divert. Then, when the heat dissipation fluid flows from the first mother spoiler 501 to the second mother spoiler 502, the heat dissipation fluid will be blocked by the first flow splitter 5021 to be split. And because the first diverter 5013 of the first female spoiler 501 and the first diverter 5021 of the second female spoiler 502 do not completely overlap, the heat dissipation fluid is affected by the first diverter 5013 and the first at different positions, respectively. The diverting member 5021 blocks and diverts, so that the heat dissipation fluid is strongly disturbed in the first spoiler 5003 and forms a turbulent flow. In this way, the time that the heat dissipation fluid stays in the first spoiler 5003 can be extended, thereby improving the heat exchange efficiency of the heat dissipation fluid.
此外,如圖2及圖4所示,第二母擾流板502靠近公擾流堆疊結構60的一側更具有多個開孔5023。如此一來,這些開孔5023便能令更多的散熱流體流至母模仁20靠近公模仁30的一側,進而加強散熱流體對母模仁20靠近公模仁30的一側之散熱效果。然,本發明並不以開孔5023的設置為限,於其他實施例中,第二母擾流板亦可無須具有開孔。In addition, as shown in FIGS. 2 and 4, a side of the second mother spoiler 502 near the public spoiler stacking structure 60 further has a plurality of openings 5023. In this way, these openings 5023 can allow more heat dissipation fluid to flow to the side of the female mold core 20 close to the male mold core 30, thereby enhancing the heat dissipation fluid's heat dissipation to the side of the female mold core 20 close to the male mold core 30. effect. However, the present invention is not limited to the arrangement of the openings 5023. In other embodiments, the second mother spoiler does not need to have openings.
此外,如圖2所示,母模仁20具有能用以容納光學成品15的模穴22。母擾流堆疊結構50具有匹配於模穴22的一凹陷結構5004。凹陷結構5004具有一中心軸C,凹陷結構5004於中心軸C處的深度E1較凹陷結構5004邊緣處的深度E2深。進一步來說,凹陷結構5004較深的區域匹配於母模仁20之模穴22中較深的區域,且模穴22中較深的區域係用以容納光學成品15較厚的區域。凹陷結構5004的設置並非用以限定本發明,於其他實施例中,母擾流堆疊結構亦可視光學成品的外形而無須具有該凹陷結構5004。In addition, as shown in FIG. 2, the female mold core 20 has a mold cavity 22 capable of receiving the optical finished product 15. The mother spoiler stack structure 50 has a recessed structure 5004 that matches the cavity 22. The recessed structure 5004 has a central axis C. The depth E1 of the recessed structure 5004 at the central axis C is deeper than the depth E2 of the recessed structure 5004. Further, the deeper area of the recessed structure 5004 matches the deeper area of the cavity 22 of the female mold core 20, and the deeper area of the cavity 22 is used to accommodate the thicker area of the optical finished product 15. The arrangement of the recessed structure 5004 is not intended to limit the present invention. In other embodiments, the mother turbulence stack structure can also be seen in the shape of the optical finished product without the recessed structure 5004.
請參閱圖6,圖6為圖3之母擾流堆疊結構的側面示意圖。為了滿足母擾流堆疊結構50中不同區域的不同散熱需求,可調整各區域之孔隙率的設計值。孔隙率為該區域總面積除以該區域中之開口面積所得到的值。舉例來說,在基準面S上,母擾流堆疊結構50中較靠近中心軸C的區域具有較大的孔隙率。舉例來說,圖6之區域ab中之孔隙率為0.4,區域ac中之孔隙率為0.5,區域ad之孔隙率為0.6且區域ae之孔隙率為0.7。也就是說,由於區域ae與中心軸C的距離最小,因此對應於光學成品較厚的區域而具有較高的散熱需求,進而需要在單位面積下令開口佔有較大的面積。而在具有較高孔隙率的區域中,便能令較多的散熱流體流過而協助光學成品較厚的區域散熱。Please refer to FIG. 6, which is a schematic side view of the mother spoiler stack structure of FIG. 3. In order to meet different heat dissipation requirements of different regions in the mother spoiler stack structure 50, the design value of the porosity of each region can be adjusted. The porosity is the value obtained by dividing the total area of the area by the opening area in the area. For example, on the reference plane S, a region closer to the central axis C in the mother spoiler stack structure 50 has a larger porosity. For example, the porosity of the region ab in FIG. 6 is 0.4, the porosity of the region ac is 0.5, the porosity of the region ad is 0.6, and the porosity of the region ae is 0.7. That is, since the distance between the area ae and the central axis C is the smallest, it has a high heat dissipation requirement corresponding to the thicker area of the optical product, and it is necessary to order the opening to occupy a larger area per unit area. In areas with higher porosity, more heat-dissipating fluid can flow through to assist the heat dissipation in the thicker areas of the optical finished product.

The third diverter 6010 and the third diverter 6020 do not completely overlap, so that the first common spoiler 601 and the second common spoiler 602 together form a local second spoiler 6000. The descriptions that do not completely overlap have been described in detail in the first embodiment, so they will not be repeated. In addition, the manner in which the male spoiler forms the second spoiler 6000 is similar to the manner in which the mother spoiler forms the first spoiler 5003 (as shown in FIG. 2), and therefore will not be described again.
再者,本實施例中第一公擾流板601僅包含一第三分流件6010,且第二公擾流板602僅包含一第三分流件6020,但本發明並不以此為限,於其他實施例中,第一公擾流板亦可更包含與第三分流件垂直的一第四分流件,且第二公擾流板更包含與第三分流件垂直的一第四分流件。而第一公擾流板的第四分流件與第二公擾流板的第四分流件不完全重疊。Furthermore, in this embodiment, the first common spoiler 601 includes only a third splitter 6010, and the second common spoiler 602 includes only a third splitter 6020, but the present invention is not limited thereto. In other embodiments, the first common spoiler may further include a fourth splitter perpendicular to the third splitter, and the second common spoiler further includes a fourth splitter perpendicular to the third splitter. .

FIG. 10 is an exploded view of the mother spoiler stack structure of FIG. 9.
本實施例之母擾流堆疊結構50a包含多個母擾流板。這些母擾流板相互堆疊而共同形成一第一擾流道。由於本實施例之這些母擾流板形成第一擾流道的方式與第一實施例之這些母擾流板形成第一擾流道5003(如圖2所示)的方式相似,故不再贅述。The mother spoiler stack structure 50a of this embodiment includes a plurality of mother spoilers. These mother spoilers are stacked on each other to form a first spoiler together. Since the manner in which the mother spoilers of this embodiment form the first spoiler is similar to the manner in which the mother spoilers of the first embodiment form the first spoiler 5003 (as shown in FIG. 2), they are no longer To repeat.
舉例來說,母擾流板包含一第一母擾流板501a及一分區隔流板503a。第一母擾流板501a包含二側邊條5010a、一第一分流件5011a、多個第二分流件5012a及一遮擋結構5013a。第一分流件5011a、這些第二分流件5012a及遮擋結構5013a介於二側邊條5010a之間。第一分流件5011a與第二分流件5012a垂直且相交。第一分流件5011a及這些第二分流件5012a連接於遮擋結構5013a。For example, the mother spoiler includes a first mother spoiler 501a and a partitioned spoiler 503a. The first mother spoiler 501a includes two side strips 5010a, a first diverter 5011a, a plurality of second diverters 5012a, and a shielding structure 5013a. The first diverter 5011a, the second diverters 5012a, and the shielding structure 5013a are interposed between the two side strips 5010a. The first diverter 5011a and the second diverter 5012a are perpendicular and intersect. The first diverter 5011a and the second diverters 5012a are connected to the shielding structure 5013a.
分區隔流板503a包含二側邊條5030a、二第二分流件5031a及一遮擋結構5032a。二第二分流件5031a及遮擋結構5032a介於二側邊條5030a之間。二第二分流件5031a連接於遮擋結構5032a。The partition baffle plate 503a includes two side strips 5030a, two second flow dividers 5031a, and a shielding structure 5032a. The two second shunts 5031a and the shielding structure 5032a are located between the two side bars 5030a. The two second shunts 5031a are connected to the shielding structure 5032a.
相較於第一實施例之第一母擾流板及分區隔流板,本實施例之第一母擾流板501a及分區隔流板503a分別額外包含有遮擋結構5013a及遮擋結構5032a。而第一母擾流板501a的遮擋結構5013a之遮擋區域與分區隔流板503a的遮擋結構5032a之遮擋區域不同。而二遮擋結構5013a、5032a不同的遮擋區域係根據光學成品的外形而被調整。Compared to the first mother spoiler and the partition baffle in the first embodiment, the first mother spoiler 501a and the partition baffle 503a in this embodiment respectively include a shielding structure 5013a and a shielding structure 5032a. The blocking area of the blocking structure 5013a of the first mother spoiler 501a is different from the blocking area of the blocking structure 5032a of the partitioned baffle plate 503a. The different shielding areas of the two shielding structures 5013a and 5032a are adjusted according to the shape of the optical finished product.
本實施例之分區隔流板503a亦由第二分流件5020a將流入面5000a分隔成一中央區域B1a及二側區域B2a、B3a。中央區域B1a介於二側區域B2a、B3a之間。而其餘之母擾流板各具有位置上分別對應分區隔流板503a之中央區域B1a及二側區域B2a、B3a的一中央區域B1a及二側區域B2a、B3a。The partition baffle 503a of this embodiment also divides the inflow surface 5000a into a central region B1a and two-side regions B2a, B3a by the second diverter 5020a. The central region B1a is located between the two-sided regions B2a and B3a. The remaining mother spoilers each have a central region B1a and two-sided regions B2a, B3a corresponding to the central region B1a and the two-sided regions B2a, B3a of the partitioned baffle 503a, respectively.
再者,第一實施例中,這些母擾流板皆具有相同的厚度,但本發明並不以此為限,本實施例中,至少二個母擾流板具有不同的厚度。舉例來說,圖10中之分區隔流板503a的厚度T1大於第一母擾流板501a的厚度T2。本實施例僅係為了方便圖式呈現而以上述態樣呈現分區隔流板503a的厚度T1及第一母擾流板501a的厚度T2。而至少二個母擾流板具有不同的厚度的用意是在於可在散熱需求較高的區域中設置較薄的母擾流板。如此一來,便能於散熱需求較高的區域中更密集地堆疊母擾流板而加強母擾流板對散熱流體的擾動效果,進而延長散熱流體於散熱需求較高之區域的停留時間。Furthermore, in the first embodiment, the mother spoilers all have the same thickness, but the present invention is not limited thereto. In this embodiment, at least two mother spoilers have different thicknesses. For example, the thickness T1 of the partition baffle 503a in FIG. 10 is greater than the thickness T2 of the first mother spoiler 501a. In this embodiment, the thickness T1 of the partition baffle plate 503a and the thickness T2 of the first female spoiler plate 501a are presented in the above manner for the convenience of illustration. The purpose of having at least two mother spoilers with different thicknesses is that a thin mother spoiler can be provided in an area with high heat dissipation requirements. In this way, the mother spoiler can be more densely stacked in the area with higher heat dissipation requirements, thereby enhancing the disturbance effect of the mother spoiler on the heat dissipation fluid, thereby extending the residence time of the heat dissipation fluid in the area with higher heat demand.

That is, the turbulence stack structure 60a of this embodiment can be regarded as a first The public disturbance flow stack structure in the embodiment is divided into three blocks.

The width W1 inside the central portion 610a is larger than the width W2 outside the central portion 610a. When the first side portion 620a, the second side portion 630a, and the central portion 610a maintain a gap G1, a thimble (not shown) provided in the mold can pass through the gap G1 to assist in demolding the optical product. In addition, the arrangement of the gap G1 can also reduce the materials required for manufacturing the turbulent flow stacking structure 60a and reduce the manufacturing cost.

以下將比較傳統無設置擾流堆疊結構之模具及本發明第一實施例至第三實施例之模具的散熱效果及利用上述各模具所製造出的光學成品之品質。將藉由四項實驗數據分別比較各模具之散熱效果及各模具所製造出的光學成品的品質。In the following, the heat dissipation effects of the conventional molds without the turbulent stack structure and the molds of the first to third embodiments of the present invention and the quality of the optical finished products manufactured by using the above molds will be compared. Four experimental data will be used to compare the heat dissipation effect of each mold and the quality of the optical finished product produced by each mold.
第一,以光學成品經過360秒冷卻後的溫度分佈為例比較各模具的散熱效果。在經過360秒的冷卻後傳統無設置擾流堆疊結構的模具使光學成品的溫度介於攝氏80度至攝氏146.12度之間、本發明第一實施例之模具使光學成品的溫度介於攝氏79.38度至攝氏139.67度之間、本發明第二實施例之模具使光學成品的溫度介於攝氏79.9度至攝氏130.9度之間,且本發明第三實施例之模具使光學成品的溫度介於攝氏73.9度至攝氏111.3度之間。根據上述數據,本發明各實施例之模具相較於傳統模具皆能更快速地降低光學成品的溫度,而具有較好的散熱效果。First, the heat dissipation effect of each mold is compared using the temperature distribution of the optical finished product after 360 seconds of cooling as an example. After 360 seconds of cooling, the traditional mold without a spoiler stack structure makes the temperature of the optical finished product between 80 ° C and 146.12 ° C. The mold of the first embodiment of the present invention makes the temperature of the optical finished product between 79.38 ° C Degrees to 139.67 degrees Celsius, the mold of the second embodiment of the present invention makes the temperature of the optical finished product between 79.9 degrees Celsius to 130.9 degrees Celsius, and the mold of the third embodiment of the present invention makes the temperature of the optical finished product between Celsius 73.9 degrees to 111.3 degrees Celsius. According to the above data, the mold of each embodiment of the present invention can reduce the temperature of the optical finished product more quickly than the traditional mold, and has a better heat dissipation effect.
以第三實施例之模具為例,並僅針對光學成品之降溫效果而言,使用根據本發明之模具僅需花費360秒即可令光學成品降溫至頂出溫度(例如為112℃)以下而能頂出模具。然而,傳統無設置擾流堆疊結構的模具在360秒冷卻時間下,光學成品仍具有高於140℃之溫度,致使光學成品無法頂出模具。Taking the mold of the third embodiment as an example, and only for the cooling effect of the optical finished product, it only takes 360 seconds to use the mold according to the present invention to cool the optical finished product to an ejection temperature (for example, 112 ° C) or less. Can eject the mold. However, under the 360-second cooling time of the traditional mold without the spoiler stack structure, the optical finished product still has a temperature higher than 140 ° C, which makes the optical finished product unable to eject from the mold.
第二,以模具及光學成品所需之冷卻時間為例比較各模具的散熱效果。傳統無設置擾流堆疊結構的模具需花費427.9秒冷卻模具及光學成品、本發明第一實施例之模具需花費397.94秒冷卻模具及光學成品、本發明第二實施例之模具需花費393.84秒冷卻模具及光學成品,且本發明第三實施例之模具需花費397.45冷卻模具及光學成品。根據上述數據,本發明各實施例之模具相較於傳統模具能以較短的時間冷卻模具及光學成品,進而具有較好的散熱效果。Second, the cooling time required for molds and optical products is taken as an example to compare the heat dissipation effects of the molds. It takes 427.9 seconds to cool the mold and optical products in the traditional mold without the spoiler stack structure. The mold in the first embodiment of the present invention takes 397.94 seconds to cool the mold and the optical product. Mold and optical products, and the mold of the third embodiment of the present invention requires 397.45 to cool the mold and optical products. According to the above data, compared with the traditional mold, the mold of each embodiment of the present invention can cool the mold and the optical finished product in a shorter time, and thus has better heat dissipation effect.
第三,由於過高的翹曲會影響光學成品的光學特性,因此以各模具製造出的光學成品之翹曲為例比較各模具製造出的光學成品的品質。又翹曲於此是指光學成品實際形成位置與預計形成位置之間的位移量。傳統無設置擾流堆疊結構的模具製造出的光學成品之翹曲介於0至0.46毫米(mm)之間、本發明第一實施例之模具製造出的光學成品之翹曲介於0毫米(mm)至0.382毫米(mm)之間、本發明第二實施例之模具製造出的光學成品之翹曲介於0毫米(mm)至0.388毫米(mm)之間且本發明第三實施例之模具製造出的光學成品之翹曲介於0毫米(mm)至0.389毫米(mm)之間。根據上述數據,相較於傳統模具所製造出的光學成品,本發明各實施例之模具所製造出的光學成品具有較低的翹曲,而令本發明各實施例之模具所製造出的光學成品具有較佳的品質。Third, because excessive warpage will affect the optical characteristics of the optical finished product, the warpage of the optical finished product manufactured by each mold is taken as an example to compare the quality of the optical finished product manufactured by each mold. Warping again refers to the amount of displacement between the actual formation position and the expected formation position of the optical finished product. The warpage of the optical finished product manufactured by the traditional mold without a spoiler stack structure is between 0 and 0.46 millimeters (mm), and the warpage of the optical finished product manufactured by the mold of the first embodiment of the present invention is between 0 mm ( mm) to 0.382 millimeters (mm), the warpage of the optical finished product manufactured by the mold of the second embodiment of the present invention is between 0 millimeters (mm) and 0.388 millimeters (mm), and the third embodiment of the present invention The warpage of the optical finished product manufactured by the mold ranges from 0 millimeter (mm) to 0.389 millimeter (mm). According to the above data, compared with the optical finished product manufactured by the traditional mold, the optical finished product manufactured by the mold of each embodiment of the present invention has lower warpage, so that the optical manufactured by the mold of each embodiment of the present invention The finished product has better quality.
第四,由於光學成品中過高的熱殘留應力會影響光學成品的光學特性,因此以各模具製造出的光學成品中之熱殘留應力為例比較各模具製造出的光學成品的品質。傳統無設置擾流堆疊結構的模具所製造出的光學成品之熱殘留應力介於0.008百萬帕(Mpa)至85.44百萬帕(Mpa)之間、本發明第一實施例之模具所製造出的光學成品之熱殘留應力介於0.027百萬帕(Mpa)至66.43百萬帕(Mpa)之間、本發明第二實施例之模具所製造出的光學成品之熱殘留應力介於0.028百萬帕(Mpa)至43.32百萬帕(Mpa)之間且本發明第三實施例之模具所製造出的光學成品之熱殘留應力介於0.02百萬帕(Mpa)至42.85百萬帕(Mpa)之間。根據上述數據,相較於傳統模具所製造出的光學成品,本發明各實施例之模具所製造出的光學成品具有較低的熱殘留應力,而令本發明各實施例之模具所製造出的光學成品具有較佳的品質。Fourth, because the excessive thermal residual stress in the optical finished product will affect the optical characteristics of the optical finished product, the thermal residual stress in the optical finished product manufactured by each mold is used as an example to compare the quality of the optical finished product manufactured by each mold. The thermal residual stress of the optical finished product manufactured by the traditional mold without a spoiler stack structure is between 0.008 million Pascals (Mpa) and 85.44 million Pascals (Mpa). The mold is manufactured by the mold of the first embodiment of the present invention. The thermal residual stress of the optical finished product is between 0.027 million Pascals (Mpa) and 66.43 million Pascals (Mpa). The thermal residual stress of the optical finished product manufactured by the mold of the second embodiment of the present invention is between 0.028 million The thermal residual stress of the optical finished product manufactured by the mold of the third embodiment of the present invention is between MPa to 43.32 million Pa (Mpa) and between 0.02 million Pa (Mpa) and 42.85 million Pa (Mpa) between. According to the above data, compared with the optical finished products manufactured by the traditional molds, the optical finished products manufactured by the molds of the embodiments of the present invention have lower thermal residual stress, so that the mold manufactured by the molds of the embodiments of the present invention The optical finished product has better quality.
根據上述實施例所揭露的模具及擾流堆疊結構,由於擾流堆疊結構位於冷卻流道中,且擾流堆疊結構之至少二第一分流件於基準面上的投影不完全重疊。因此,當散熱流體通過冷卻流道時,便會於擾流道中形成紊流,而延長散熱流體停留於擾流堆疊結構中的時間。如此一來,便能增加與擾流堆疊結構的熱交換效率,而提升散熱流體之散熱效果。另一方面,當擾流堆疊結構位於母模仁的第一冷卻流道中而為母擾流堆疊結構時,不完全重疊的至少二第一分流件便能使散熱流體於第一擾流道中形成紊流,進而提升散熱流體協助母模仁散熱的效果。According to the mold and the spoiler stack structure disclosed in the above embodiments, since the spoiler stack structure is located in the cooling runner, and the projections of at least two first shunt members of the spoiler stack structure on the reference plane do not completely overlap. Therefore, when the heat dissipation fluid passes through the cooling flow channel, turbulence is formed in the spoiler channel, and the time for the heat dissipation fluid to stay in the spoiler stack structure is prolonged. In this way, the heat exchange efficiency with the turbulent stack structure can be increased, and the heat dissipation effect of the heat dissipation fluid can be improved. On the other hand, when the spoiler stack structure is located in the first cooling flow channel of the female mold core and is a mother spoiler stack structure, at least two first shunts that are not completely overlapped can form a heat dissipation fluid in the first spoiler channel. The turbulence improves the effect of the heat-dissipating fluid to assist the female mold core to dissipate heat.
此外,由於第一擾流道係由這些母擾流板所拼湊而成。因此,使用者能依照不同光學成品的溫度分佈重新排列母擾流板,而拼湊出對應不同溫度分佈的第一擾流道。如此一來,便無需藉由重新切削的方式提供具有專屬冷卻流道設計的模具,而降低製造光學成品的成本。In addition, since the first spoiler is made up of these mother spoilers. Therefore, the user can rearrange the mother spoiler according to the temperature distribution of different optical products, and piece together the first spoiler corresponding to the different temperature distribution. In this way, there is no need to provide a mold with a dedicated cooling runner design by re-cutting, thereby reducing the cost of manufacturing the optical finished product.
