Description
本申請案係為於2010年10月2日提出申請之根據35 U.S.C.§121的美國專利申請案第12/898,824號的一部分延續申請案,於此其之全文併入本案以為參考資料。 This application is a continuation-in-part of U.S. Patent Application Serial No. 12/898,824, filed on Oct. 2, 2010, which is hereby incorporated by reference.
本發明一般係有關於擠出成型裝置。具體地,本發明係有關於具有可變節距用於搭配該成型裝置的使用的模組化鑄模夾住總成。 The invention generally relates to extrusion molding apparatus. In particular, the present invention relates to a modular mold clamping assembly having a variable pitch for use with the molding apparatus.
傳統旋轉式擠出吹塑成型裝置典型地具有一安裝位在一旋轉軸上的結構框架。該結構框架具有複數之安裝於其上的鑄模並且於業界係為所熟知的一輪。當該輪轉動時,該複數之鑄模係轉動通過一擠出模擠出一連續的型坯。每一鑄模典型地包括二鑄模半殼體,每一半殼體其中包含一半鑄模腔室,以致當該等鑄模半殼體閉合時,該鑄模界定一與待成型的該物件,諸如一容器之構態相對應的鑄模腔室。每一鑄模逐一地係與處於一開啟構態下的二鑄 模半殼體轉動通過該擠出模。每一鑄模之該等鑄模半殼體接著環繞著該型坯閉合用以將該型坯圍住於由該等鑄模半殼體所界定的該鑄模中。接著將一吹放針插入位於該閉合鑄模內的該型坯中並導入內壓至該型坯,強制該型坯膨脹並符合該鑄模腔室之該構態。該成型物件接著加以冷卻並開啟該鑄模以將該成型物件自該鑄模取出。 Conventional rotary extrusion blow molding devices typically have a structural frame mounted on a rotating shaft. The structural frame has a plurality of molds mounted thereon and is well known in the industry. As the wheel rotates, the plurality of molds are rotated through an extrusion die to extrude a continuous parison. Each mold typically includes two mold half-shells, each half-shell containing one half of the mold cavity such that when the mold half-shell is closed, the mold defines a structure to be formed, such as a container The corresponding mold cavity. Each mold is tied one by one with two castings in an open configuration The mold half-shell rotates through the extrusion die. The mold halves of each mold are then closed around the parison for enclosing the parison in the mold defined by the mold halves. A blow pin is then inserted into the parison in the closed mold and an internal pressure is introduced into the parison, forcing the parison to expand and conform to the configuration of the mold cavity. The shaped article is then cooled and the mold is opened to remove the shaped article from the mold.
當在該等型坯之吹放之前將該二鑄模半殼體夾住在一或更多個型坯上以構成塑膠容器時,需高夾住力以將該等型坯上的該等鑄模半殼體閉合,在吹塑成型期間掐掉塑膠並固持該等鑄模半殼體閉合。傳統的鑄模夾具總成係安裝在支撐該總成的框架上,並且當致動時,將夾住力由位在該鑄模之一側邊上的一傳動裝置經由框架傳送至該鑄模之另一側邊上。此意指支撐該等鑄模的該框架必需足夠地堅固以對抗經由該框架傳送的該高夾住力所施加的彎曲力矩。由該夾住力所造成的該框架之變形係非為所期望的,因為變形無法讓該鑄模相互平行地面對以閉合。 When the two mold half-shells are clamped to one or more parisons to form a plastic container prior to blowing of the parisons, high clamping forces are required to mold the molds on the parisons The half-shell is closed, the plastic is removed during blow molding and the mold half-shells are closed. A conventional mold jig assembly is mounted on a frame supporting the assembly, and when actuated, the clamping force is transmitted to the other of the molds via a frame by a transmission located on one side of the mold On the side. This means that the frame supporting the molds must be sufficiently strong to withstand the bending moments exerted by the high clamping forces transmitted through the frame. The deformation of the frame caused by the clamping force is not desirable because the deformation does not allow the molds to face each other in parallel to close.
上述該吹塑成型裝置典型地係為成本高、重的機器,其需大量的專門技能以調整及維護。例如,當一鑄模夾具需要維修時,該整個輪必需在該鑄模夾具繼續運作時脫機(off-line)。此外,假若改變該吹塑成型裝置之鑄模夾具的數目以容納一不同尺寸的鑄模,則拆卸與重新裝配該裝置所需的成本及時間係為顯著的。 The blow molding apparatus described above is typically a costly, heavy machine that requires a great deal of expertise to adjust and maintain. For example, when a mold jig requires repair, the entire wheel must be off-line while the mold jig continues to operate. Furthermore, if the number of mold jigs of the blow molding apparatus is changed to accommodate a mold of a different size, the cost and time required to disassemble and reassemble the apparatus are remarkable.
於對現存技術之改良的一嘗試上,美國專利第7,611,657號揭示一用於旋轉式或梭式吹塑成型機的鑄模夾 具總成。該夾具總成係安裝在一框架上並包括一鑄模開啟及閉合傳動裝置其與該框架無關地連接至該二鑄模半殼體,因此當該等鑄模半殼體閉合時,夾住力並未經由該框架傳送至該等鑄模半殼體。因此,於吹塑成型期間將該等鑄模半殼體固持在一起所需的高夾住力並未自該鑄模之一側邊經由該機器框架傳送至該鑄模之另一側邊。 In an attempt to improve the existing technology, a mold holder for a rotary or shuttle blow molding machine is disclosed in U.S. Patent No. 7,611,657. With assembly. The clamp assembly is mounted on a frame and includes a mold opening and closing transmission that is coupled to the two mold half-shells independently of the frame, such that when the mold half-shells are closed, the clamping force is not Transfer to the mold half-shells via the frame. Thus, the high clamping force required to hold the mold halves together during blow molding is not transferred from the side of one of the molds through the machine frame to the other side of the mold.
因此,具有對於考慮到裝置之容易維修保養且易於構態的一改良式成型裝置及鑄模夾具總成的需要。同時需要降低該成型裝置之複雜性以有助於減少該成型裝置之製造與作業成本。此外,亦有對用於完成上述目的之模組化鑄模夾具總成的需要,其中該模組化鑄模夾具具有可變節距或是可徑向地調整以容許在該等鑄模夾具中由各別鑄模構成的鑄模圈(mold circle)製作成較大或是較小以容納不同尺寸的鑄模使與該成型製程相關聯的廢料減至最少。 Accordingly, there is a need for an improved forming apparatus and mold jig assembly that takes into account the ease of maintenance of the apparatus and that is easy to conform to. At the same time, the complexity of the forming apparatus needs to be reduced to help reduce the manufacturing and operating costs of the forming apparatus. In addition, there is a need for a modular mold fixture assembly for accomplishing the above objectives, wherein the modular mold fixture has a variable pitch or can be radially adjusted to allow for individual differences in the mold fixtures. The mold circle formed by the mold is made larger or smaller to accommodate different sized molds to minimize waste associated with the forming process.

The central slot also cooperates with the mounting member 210 to secure the radial adjustment mechanism 200 to the turntable 12. In the exemplary embodiment, the outer slots are not so precisely machined. Accordingly, the outer slots are used to secure the radial adjustment mechanism 200 to the turntable 12 and are not used to align with the radial adjustment mechanism 200 positioned on the turntable 12. However, other configurations may be used without departing from the scope of the invention.
於該示範具體實施例中,每一安裝構件210具有一T形狀構態其係經組配以與一各別的T形狀槽縫202相配合並於其中滑動。如於圖13中所示,該等安裝構件210之T形狀構態的頭部與該等槽縫202之該等肩部分208之肩部分相配合以維持該等安裝構件210位於該等槽縫202中。提供安裝五金製品以自該等安裝構件210延伸通過至該轉動台12之該等安裝開口25以將該等安裝構件210及該徑向調整機構200牢固至該轉動台12。然而,可提供其他型式的安裝構件而未背離本發明之範疇。於該示範具體實施例中,圖供一鍵槽212(圖12)位在緊鄰該轉動台12之該等中心安裝開口處。該鍵槽212與一各別的安裝構件210相配合以對準 該安裝構件210及該徑向調整機構200,並以防止該徑向調整機構200與該鍵槽212之該縱軸橫向地移動。 In the exemplary embodiment, each mounting member 210 has a T-shaped configuration that is configured to mate with and slide in a respective T-shaped slot 202. As shown in FIG. 13, the heads of the T-shaped configuration of the mounting members 210 cooperate with the shoulder portions of the shoulder portions 208 of the slots 202 to maintain the mounting members 210 in the slots. 202. Mounting hardware is provided to extend from the mounting members 210 to the mounting openings 25 of the turntable 12 to secure the mounting members 210 and the radial adjustment mechanism 200 to the turntable 12. However, other types of mounting members may be provided without departing from the scope of the invention. In the exemplary embodiment, a keyway 212 (Fig. 12) is positioned adjacent the central mounting openings of the turntable 12. The keyway 212 cooperates with a respective mounting member 210 to align The mounting member 210 and the radial adjustment mechanism 200 prevent the radial adjustment mechanism 200 from moving laterally with the longitudinal axis of the keyway 212.
如以上所說明,該中央槽縫係按適當尺寸製作以具有緊密容限容許該中央槽縫精確地與該安裝構件210對準,以正確地和位在該轉動台12上的該徑向調整機構200對準。該中央槽縫亦與該安裝構件210相配合以將該徑向調整機構200牢固至該轉動台12。該中央安裝開口25因而亦係經機密加工以維持該徑向調整機構200於正確位置。同時如先前所陳述,該等外槽縫並未如此精確地加工。因此,當該等外安裝開口25係用以將該徑向調整機構200牢固至該轉動台12並且非用以與位在該轉動台12上的該徑向調整機構200對準時,該等外安裝開口25可以較低的精確度加工。然而,可使用其他的構態而未背離本發明之範疇。 As explained above, the central slot is sized to have a tight tolerance to allow the central slot to accurately align with the mounting member 210 for proper alignment with the radial adjustment on the rotating table 12. The mechanism 200 is aligned. The central slot also cooperates with the mounting member 210 to secure the radial adjustment mechanism 200 to the turntable 12. The central mounting opening 25 is thus also machined to maintain the radial adjustment mechanism 200 in the correct position. At the same time, as previously stated, the outer slots are not processed so precisely. Therefore, when the outer mounting openings 25 are used to secure the radial adjustment mechanism 200 to the rotating table 12 and are not intended to be aligned with the radial adjustment mechanism 200 located on the rotating table 12, The mounting opening 25 can be machined with less precision. However, other configurations may be used without departing from the scope of the invention.

參考圖9及10,一支撐桿240延伸通過底座112並 係藉由附裝至該安裝托架118的一托架加以固持。該托架容許該支撐桿240轉動而依然捕捉該支撐桿240,因此當該支撐桿240轉動時,該模組化鑄模夾具總成100徑向地移動。該支撐桿240在遠離鑄模托板126、128的一方向上自該底座112延伸。於該示範具體實施例中,該支撐桿240係位設最近於該模組化鑄模夾具總成100之該重心處,以致大約該模組化鑄模夾具總成100之½重量係分佈在該支撐桿240之任一側邊上,儘管可使用具有一或更多個支撐構件的其他具體實施例,但未背離本發明之範疇。該支撐桿240具有一第一調整機構242,諸如,但非限定在與一第二調整機構244相配合的螺紋,諸如,但非限定在自該吹塑成型機延伸位在一支撐裝置具246上的螺帽或是相似物。該第一調整機構242與該第二調整機構244之配合容許如所需地調整該模組化鑄模夾具總成100,如將更為完整地說明。於所示的示範具體實施例中,該支撐裝置具246係為一中心圓盤其具有開口用以收納該等支撐桿240於其中。然而,可使用其他裝置具而未背離本發明之範疇。 Referring to Figures 9 and 10, a support rod 240 extends through the base 112 and It is held by a bracket attached to the mounting bracket 118. The bracket allows the support bar 240 to rotate while still capturing the support bar 240, so that the modular mold clamp assembly 100 moves radially as the support bar 240 rotates. The support bar 240 extends from the base 112 in a direction away from the mold trays 126, 128. In the exemplary embodiment, the support bar 240 is located closest to the center of gravity of the modular mold jig assembly 100 such that approximately 1⁄2 of the weight of the modular mold jig assembly is distributed over the support. On either side of the rod 240, although other specific embodiments having one or more support members can be used, without departing from the scope of the invention.

The nut on it or something similar. The cooperation of the first adjustment mechanism 242 and the second adjustment mechanism 244 allows the modular mold fixture assembly 100 to be adjusted as desired, as will be more fully described. In the exemplary embodiment shown, the support device 246 is a central disc having an opening for receiving the support rods 240 therein. However, other devices may be used without departing from the scope of the invention.
在作業上,如先前說明,該模組化鑄模夾具總成100係經裝配該輪10之該轉動台12。將水管理軟管附裝至每一總成100之一水連接構件。如係於業界所熟知,供給水以冷卻該鑄模。將空氣軟管附裝至每一總成100之一空氣連接構件。使用空氣以將空氣吹入該鑄模腔室中並用以操作該等必需裝置以有助於將容器自該腔室取出,二者係為業界所熟知。 In operation, the modular mold fixture assembly 100 is assembled to the turntable 12 of the wheel 10 as previously described. A water management hose is attached to one of the water connection members of each assembly 100. As is well known in the art, water is supplied to cool the mold. An air hose is attached to one of the air connecting members of each of the assemblies 100. Air is used to blow air into the mold cavity and to operate the necessary means to facilitate removal of the container from the chamber, both of which are well known in the art.
如於圖2中所示,讓該等半殼體132及134處於開啟位置並收回傳動裝置163,輪10之轉動移動了該等開啟的鑄模半殼體132、134通過該擠製台至由一擠製頭所擠製的複數之型坯的任一側邊。該輪10之轉動亦沿著一凸輪槽縫之一徑向向外的部分移動從動件156以徑向向外地滑動車148由圖2之該位置至圖1之該位置。此移動逆時針地轉動臂144由圖2之該位置至圖1之該位置。 As shown in FIG. 2, the half-shells 132 and 134 are in the open position and the transmission 163 is retracted, and the rotation of the wheel 10 moves the open mold half-shells 132, 134 through the extrusion station. Either one side of a plurality of parisons extruded by the extrusion head. The rotation of the wheel 10 also moves the follower 156 along a radially outward portion of a cam slot to slide the carriage 148 radially outward from the position of Figure 2 to that position of Figure 1. This movement rotates the arm 144 counterclockwise from the position of Figure 2 to that position of Figure 1.
臂144由圖2之該位置至圖1之該位置的轉動將傳動裝置163延伸以將移動構件162移離該端部構件113。該移動構件之移動使鑄模半殼體132由該開啟位置移動至閉合位置。該移動構件之移動亦致動鑄模移動機構以將該移動桿168移離端部構件113,轉動臂172並將鑄模半殼體134由該開啟位置移動至該閉合位置。調整桿180與彈簧組184之間的連接,因此彈簧組184在該鑄模閉合時係經壓縮。 Movement of the arm 144 from the position of FIG. 2 to the position of FIG. 1 extends the transmission 163 to move the moving member 162 away from the end member 113. Movement of the moving member moves the mold half-shell 132 from the open position to the closed position. Movement of the moving member also actuates the mold moving mechanism to move the moving rod 168 away from the end member 113, rotate the arm 172 and move the mold half-shell 134 from the open position to the closed position. The connection between the rod 180 and the spring set 184 is adjusted so that the spring set 184 is compressed when the mold is closed.
在該鑄模閉合期間或是之後,施加在鑄模半殼體134上的夾住力係經由鑄模移動機構直接地傳送至傳動裝置163。施加在該鑄模半殼體132上的一相等且方向相反的夾住力係直接地經由構件162傳送至該傳動裝置。夾住力係經由介於十字插銷170與依次地附裝至端部構件113的固定插銷142之間的桿124傳送,該端部構件依次地安裝至徑向調整機構200。夾住力未經由框架構件110傳送。因此,該框架110並未承受由固持鑄模132及134閉合的高夾住力所導致的彎曲力矩。該框架110,以及因此,該徑向調整機構200不需強化以抵抗彎曲力矩。由於重量減小, 可使用較小、更有效率的馬達以操作該機器。 During or after the mold is closed, the clamping force applied to the mold half-shell 134 is directly transmitted to the transmission 163 via the mold moving mechanism. An equal and opposite clamping force applied to the mold half-shell 132 is transmitted directly to the transmission via the member 162. The clamping force is transmitted via a rod 124 between the cross pin 170 and a fixed pin 142 that is sequentially attached to the end member 113, which end member is sequentially mounted to the radial adjustment mechanism 200. The clamping force is not transmitted via the frame member 110. Therefore, the frame 110 does not withstand the bending moment caused by the high clamping force that holds the molds 132 and 134 closed. The frame 110, and thus the radial adjustment mechanism 200, does not need to be reinforced to resist bending moments. Due to the weight reduction, A smaller, more efficient motor can be used to operate the machine.
在該鑄模閉合以捕捉該型坯之後,輪10之轉動將該等閉合的鑄模半殼體移離該擠製台而至一吹塑台於該處吹塑該等型坯,以及,在將該等吹塑的型坯冷卻之後,至一射出成型台於該處將該鑄模開啟供吹塑成型容器之射出成型。於轉動至該射出成型台期間,從動件156藉由凸輪軌道徑向地向內移動,因此臂端部146係相對於固定插銷142徑向地向內移動,傳動裝置163係如圖2中所示般收回,並且該等托板126、128以及鑄模半殼體132、134係藉由該移動構件162及鑄模移動機構之移動而開啟。托板126及鑄模半殼體132係直接地連接至移動構件162並在感應該構件之移動後開啟。托板128及鑄模半殼體134係藉由移動桿168朝向側構件113之移動而開啟,與臂172之轉動及桿180移離側構件113並朝向側構件111相一致。 After the mold is closed to capture the parison, the rotation of the wheel 10 moves the closed mold half-shell away from the extrusion station to a blow molding station where the parison is blown, and After the blown parisons are cooled, the injection molding station is opened there to open the mold for injection molding of the blow molded container. During the rotation to the injection molding station, the follower 156 is moved radially inward by the cam track, so the arm end portion 146 is moved radially inward relative to the fixed pin 142, and the transmission device 163 is as shown in FIG. Retracted as shown, and the pallets 126, 128 and the mold half-shells 132, 134 are opened by movement of the moving member 162 and the mold moving mechanism. The pallet 126 and the mold half-shell 132 are directly coupled to the moving member 162 and open after sensing the movement of the member. The pallet 128 and the mold half-shell 134 are opened by the movement of the moving rod 168 toward the side member 113, and the rotation of the arm 172 and the rod 180 are moved away from the side member 113 and toward the side member 111.
於輪10之作業期間,對於一特別的鑄模夾具總成會有問題並非罕見。同時常見的是具有預定安排維修保養的問題。於該技藝之目前的狀態下,為了對一特別的鑄模夾具總成進行修理或是執行維修保養,當該總成仍係附裝至該輪時,停止該輪之運轉並對該鑄模夾具總成執行該修理或維修保養。如此會造成對於整個作業大的停工期並引人注目地影響作業之生產率。可交替地,該輪之運轉係經停止以及自該等托板及該輪之軸取出該鑄模夾具總成並以另一鑄模夾具總成取代。然而,當該等鑄模夾具總成係於複數點處附裝至該輪之結構,此處理過程花費大量的時 間及費用而得以完成,從而引人注目地影響到作業之生產率並需要一熟練的作業員效勞以完成該轉移作業。 It is not uncommon for a particular mold fixture assembly to be problematic during the operation of the wheel 10. At the same time, it is common to have problems with scheduled maintenance. In the current state of the art, in order to repair or perform maintenance on a particular mold fixture assembly, when the assembly is still attached to the wheel, the operation of the wheel is stopped and the mold clamp is always Perform the repair or maintenance. This can result in a large downtime for the entire job and a dramatic impact on the productivity of the job. Alternatively, the operation of the wheel is stopped and the mold clamp assembly is removed from the pallets and the axle of the wheel and replaced with another mold clamp assembly. However, when the mold fixture assembly is attached to the structure of the wheel at a plurality of points, the process takes a lot of time. The cost and the cost are completed, which significantly affects the productivity of the job and requires a skilled operator to complete the transfer.
對比地,於此說明的該模組化鑄模夾具總成100克服了與先前技術相關聯的問題。當所有的該模組化鑄模夾具總成100之組件係安裝至該框架110時,大大地有助於將該獨立的模組化鑄模夾具總成100自該輪10取出。為了對一特別的鑄模夾具總成進行修理或是執行維修保養,停止該輪之運轉並將該鑄模夾具總成取出以另一模組化鑄模夾具總成100更換。當所有該等組件係附裝至該框架100時,而非附裝至該輪10之結構構件,維修保養人員簡單地卸下將該模組化鑄模夾具總成100之該框架110的該徑向調整機構200附裝至該輪10之該硬體,並自該支撐裝置具246鬆開該支撐桿240。接著將該模組化鑄模夾具總成100取出並插入一新的模組化鑄模夾具總成100。該新的模組化鑄模夾具總成100之該框架110的該徑向調整機構200係藉由使用該硬體而安裝至該輪10。同時將該新的模組化鑄模夾具總成100之該支撐托架插入於該支撐裝置具246中。如此容許對該輪以最少的停工期完成修理或維修保養,從而使對作業之生產率造成的影響降至最低。此外,能夠由維修保養程度的人員完成該模組化鑄模夾具總成100之更換而非由工廠技師進行,因而降低成本。 In contrast, the modular mold fixture assembly 100 described herein overcomes the problems associated with the prior art. When all of the components of the modular mold fixture assembly 100 are mounted to the frame 110, it greatly facilitates removal of the separate modular mold fixture assembly 100 from the wheel 10. In order to repair or perform maintenance on a particular mold fixture assembly, the operation of the wheel is stopped and the mold clamp assembly is removed for replacement with another modular mold fixture assembly 100. When all of the components are attached to the frame 100, rather than to the structural members of the wheel 10, the service technician simply removes the diameter of the frame 110 of the modular mold fixture assembly 100. The hardware attached to the wheel 10 is attached to the adjustment mechanism 200, and the support bar 240 is released from the support device 246. The modular mold fixture assembly 100 is then removed and inserted into a new modular mold fixture assembly 100. The radial adjustment mechanism 200 of the frame 110 of the new modular mold fixture assembly 100 is mounted to the wheel 10 by the use of the hardware. At the same time, the support bracket of the new modular mold clamping fixture assembly 100 is inserted into the support device 246. This allows the wheel to be repaired or repaired with minimal downtime, minimizing the impact on productivity. In addition, the replacement of the modular mold jig assembly 100 can be accomplished by a maintenance technician rather than by a factory technician, thereby reducing costs.
使用該模組化鑄模夾具總成100亦容許使該輪10之結構簡化。當每一模組化構件總成100係為獨立的時,該模組化鑄模夾具總成100之不同的組件並未安裝至在該 輪10之該等轉動台12之間延伸的軸或平板。此外,該底座構件112、該等端部構件111、113及該等徑向調整機構200係以具有當安裝在該輪10中時使用作為支撐件的結構性強度及整體性的材料製成。因此,於此所說明搭配該等模組化鑄模夾具總成100使用的該輪10係由目前所使用中的該等輪大大地加以簡化。當該等模組化鑄模夾具總成100在該輪10之該等轉動台12之間提供必需的結構性支撐件時,先前所需的該等軸與平板係經排除。如此容許該吹塑成型機之該輪10具有更多的開啟空間,使對該吹塑成型機之修理更為容易。使用該等模組化鑄模夾具總成100作為支撐件亦減少該吹塑成型機之整體成本,因為具有結構性模組化鑄模夾具總成與具有結構性軸及平板比較係較不昂貴。 The use of the modular mold fixture assembly 100 also allows for a simplified construction of the wheel 10. When each modular component assembly 100 is independent, the different components of the modular mold fixture assembly 100 are not mounted to A shaft or plate extending between the rotating stages 12 of the wheel 10. Further, the base member 112, the end members 111, 113, and the radial adjustment mechanisms 200 are made of a material having structural strength and integrity as a support when mounted in the wheel 10. Accordingly, the wheel 10 used with the modular mold fixture assembly 100 described herein is greatly simplified by the wheels currently in use. When the modular mold jig assembly 100 provides the necessary structural support between the rotating stages 12 of the wheel 10, the previously required axes and plates are eliminated. This allows the wheel 10 of the blow molding machine to have more open space, making repair of the blow molding machine easier. The use of such modular mold jig assemblies 100 as support members also reduces the overall cost of the blow molding machine because the structural modular mold jig assembly is less expensive than having a structural shaft and plate.
儘管該底座構件112、該等端部構件111、113及該等徑向調整機構200必需以具有足夠強度特性以支撐該等組件並提供針對該輪10所需的結構整體性的材料製成,但如先前所說明,當該等彎曲力矩並未轉移至該框架110時,該框架110不需以具有能夠抵抗由固持鑄模132及134閉合的高夾住力所施加的該等彎曲力矩的材料製成。因此,該框架110不需加以強化以抵抗彎曲力矩,從而容許該框架110以相對地重量較輕的材料製成。如此有助於取出及更換該模組化鑄模夾具總成100並減少製造該框架110之材料成本。 Although the base member 112, the end members 111, 113, and the radial adjustment mechanisms 200 must be made of a material having sufficient strength characteristics to support the components and provide the structural integrity required for the wheel 10, However, as previously explained, when the bending moments are not transferred to the frame 110, the frame 110 need not be material having the bending moments that are resistant to the high clamping forces held by the holding molds 132 and 134. production. Thus, the frame 110 need not be reinforced to resist bending moments, thereby allowing the frame 110 to be made of relatively light weight materials. This facilitates the removal and replacement of the modular mold fixture assembly 100 and reduces the material cost of manufacturing the frame 110.
於先前技術中,使用該吹塑成型機製造的不同尺寸大小的容器所需要的是使用不同之輪,作為該等鑄模 台之徑向定位以容納該等不同鑄模尺寸需要的不同尺寸之轉動台。因此,當每一輪經設計用於一特定鑄模尺寸時,與符合應用之需求相關聯的該存量會為大量的或是當於該等輪中使用較小的鑄模時,由該等輪所產生的浪費數量係為顯著的,多數材料係於該等鑄模之間浪費掉。 In the prior art, it is required to use different wheels for the different sized containers manufactured using the blow molding machine as the molds. The table is radially positioned to accommodate different sized rotating stages required for different mold sizes. Thus, when each wheel is designed for a particular mold size, the inventory associated with the application's needs will be large or generated by the wheels when smaller molds are used in the wheels. The amount of wasted is significant, and most materials are wasted between the molds.
成對比地,根據本發明,可容易地調整該模組化鑄模夾具總成而移動更接近或是遠離該軸20、21或該輪10之中心。易言之,該鑄模圓之直徑,其係由所有該等模組化鑄模夾具總成所組成,可視所製造之容器的尺寸以及該等鑄模半殼體132、134之尺寸而定構成較大或是較小。為了移動每一模組化鑄模夾具總成,鬆開該等安裝構件210以容許該徑向調整機構200相對該等安裝構件210移動。該第一調整機構242接著經嚙合以將該支撐桿240及該模組化鑄模夾具總成100移動至相對該支撐裝置具246及該等轉動台12的該所需位置。例如,於一方向上旋轉該第一調整機構242致使該模組化鑄模夾具總成100移離該輪100之中心,同時於一相反方向上旋轉該第一調整機構242致使該模組化鑄模夾具總成100移向該輪100之中心。一經正確地調整,該等安裝構件210經繃緊以防止該等安裝構件210相對於該等槽縫非所欲地移動,從而維持該模組化鑄模夾具總成100位在相對於該等轉動台12及該輪10之適當位置。可使用計量器或相似物以監控及精確地控制該等模組化鑄模夾具總成之移動以及控制其相對於該等轉動台12之定位。如此容許該等模組化鑄模夾具總成精確地移向或 是移離該輪之中心並維持在適當位置。如此,介於與該等模組化鑄模夾具總成相鄰及其之各別鑄模之間的該空間係減至最小,從而使鑄模間浪費的材料量降至最低,藉此減少所產生的碎片量。 In contrast, in accordance with the present invention, the modular mold fixture assembly can be easily adjusted to move closer to or away from the center of the shaft 20, 21 or the wheel 10. In other words, the diameter of the mold circle is composed of all of the modular mold clamping fixture assemblies, which may be larger depending on the size of the manufactured container and the size of the mold half shells 132, 134. Or smaller. To move each modular mold clamp assembly, the mounting members 210 are loosened to permit movement of the radial adjustment mechanism 200 relative to the mounting members 210. The first adjustment mechanism 242 is then engaged to move the support bar 240 and the modular mold clamp assembly 100 to the desired position relative to the support device 246 and the rotary table 12. For example, rotating the first adjustment mechanism 242 in one direction causes the modular mold fixture assembly 100 to move away from the center of the wheel 100 while rotating the first adjustment mechanism 242 in an opposite direction to cause the modular mold fixture Assembly 100 moves toward the center of the wheel 100. Once properly adjusted, the mounting members 210 are tightened to prevent the mounting members 210 from moving undesirably relative to the slots, thereby maintaining the modular mold holder assembly 100 in position relative to the rotation. The appropriate position of the table 12 and the wheel 10. Meters or the like can be used to monitor and accurately control the movement of the modular mold fixture assemblies and to control their positioning relative to the rotary tables 12. This allows the modular mold fixture assembly to move precisely or It is removed from the center of the wheel and maintained in place. In this way, the space between the molds adjacent to the modular mold jig assemblies and their respective molds is minimized, thereby minimizing the amount of material wasted between the molds, thereby reducing the resulting The amount of debris.
根據於此所說明的本發明,容納不同構態所需之存量係減至最少。當該等輪不需軸等時,該等輪可製成以容納不同的構態。該等支撐裝置具246及該輪10之該等開啟空間及該徑向調整機構200及該模組化鑄模夾具總成100之該等支撐桿240容許該等模組化鑄模夾具總成100經移動以容納不同的容器尺寸,從而容許該等相同的模組化鑄模夾具總成100移動以容納不同尺寸之鑄模,藉此減少對於特定機器製造特定鑄模夾具總成或特定轉動台12的需要。 In accordance with the invention as described herein, the inventory required to accommodate different configurations is minimized. When the wheels do not require a shaft or the like, the wheels can be made to accommodate different configurations. The support devices 246 and the opening spaces of the wheel 10 and the support rods 240 of the radial adjustment mechanism 200 and the modular mold clamping assembly 100 allow the modular mold clamping assembly 100 to pass through Moving to accommodate different container sizes allows the same modular mold fixture assembly 100 to be moved to accommodate different sized molds, thereby reducing the need to manufacture a particular mold clamp assembly or a particular rotary table 12 for a particular machine.
