Description
本發明係關於鞋類製造之技術領域，詳言之，係關於鞋底壓縮成形技術，更詳言之係關於模鎖機構。The present invention relates to the technical field of footwear manufacturing, in particular, to a sole compression forming technology, and more particularly to a mold locking mechanism.
目前鞋底之製作主要採用壓縮成形機，其係將材料塑形於模具中，亦即將材料裝載入模具內並對其加熱特定時間，之後開啟模具並將鞋底產品自模具中取出。Currently, the soles are mainly made by compression molding machines, which mold the material into a mold, that is, the material is loaded into the mold and heated for a specific time, and then the mold is opened and the sole product is taken out of the mold.
概言之，鞋底壓縮模具通常由以鉸鏈相連之上、下兩半模體構成，兩半模體之間形成有一模穴，用以容納材料，藉此為鞋底產品塑形。加熱期間，模具緊密閉合，上、下半模由一錐狀模閂固定。當模具開啟時，此模閂自模具拆離。模閂之固定與拆離皆仰賴人工操作，亦即須由人員持槌敲擊模閂，因此存在意外風險。並且，模閂之拆離與固定皆需耗用一定時間，不利於生產績效。In general, the sole compression mold is usually composed of an upper and lower mold halves connected by a hinge, with a mold cavity formed between the two mold halves to accommodate the material and thereby shape the sole product. During the heating period, the mold is tightly closed, and the upper and lower mold halves are fixed by a conical mold latch. When the mold is opened, the mold latch is detached from the mold. The fixing and removal of the mold latch both rely on manual operation, that is, the mold latch must be hit by a hammer, so there is an accidental risk. In addition, the removal and fixing of the mold latch both take a certain amount of time, which is not conducive to production performance.
是以此領域中需要一種可牢固鎖合模具且可迅速開閉之機構。Therefore, a mechanism that can firmly lock the mold and open and close quickly is needed in this field.
本發明為此需求提供一種解決方案。The present invention provides a solution to this demand.
據此，本發明之目的在於提供一種用於鞋底壓形模具之鎖模機構，其可確保模具緊密閉合，然亦可幫助達成模具之迅速便利啟閉。Accordingly, the object of the present invention is to provide a locking mechanism for a sole pressing mold, which can ensure that the mold is tightly closed, but can also help to achieve quick and convenient opening and closing of the mold.
為達成上述目的，依據本發明一實施例之模鎖機構包含：To achieve the above-mentioned purpose, a mold lock mechanism according to an embodiment of the present invention includes:
一鎖閂，固定於一半模體；該鎖閂呈T形，具有二側臂，各側臂之上方角落形成斜角；A lock bolt is fixed to one half of the mold body; the lock bolt is T-shaped and has two side arms, and the upper corners of each side arm form an oblique angle;
一限位組，固定於另一半模體，該限位組包含二鏡像對稱限位件，各限位件具有凹入段，且二限位件之安排使得二凹入段共同形成一可緊密包覆鎖閂T形鎖頭之C形，各限位件具有兩端，一端設有通孔以供限位件經一旋轉軸而裝設於上半體，且另一端設有凹洞以供一退鎖柄安裝於其中，藉此二限位件於模具閉合時緊密扣合鎖閂，且當二退鎖柄因受力而彼此遠離時分開，以允許模具開啟。A limiter set is fixed to the other half of the mold, and the limiter set includes two mirror-symmetrical limiters, each of which has a recessed section, and the two limiters are arranged so that the two recessed sections together form a C-shape that can tightly cover the T-shaped lock head of the lock bolt. Each limiter has two ends, one end is provided with a through hole for the limiter to be installed on the upper half through a rotating shaft, and the other end is provided with a recessed hole for a unlocking handle to be installed therein, whereby the two limiters tightly lock the lock bolt when the mold is closed, and when the two unlocking handles are separated from each other due to force, they are separated to allow the mold to be opened.
如圖1及圖2所示，包含本發明鎖模機構20之模具10係具有鞋底製造模具之普遍特徵。詳言之，模具10包括由一鉸鏈(圖未示)接合之上半體11與下半體12，及一位於上半體11及下半體12間之塑形區13。As shown in Fig. 1 and Fig. 2, the mold 10 including the mold locking mechanism 20 of the present invention has the common features of the mold for manufacturing the sole. Specifically, the mold 10 includes an upper body 11 and a lower body 12 connected by a hinge (not shown), and a shaping area 13 between the upper body 11 and the lower body 12.
本發明之鎖模機構20包括一上部件21及一下部件22，如圖3所示。圖3中顯示之上部件21及下部件22彼此平行。於實務中，上部件21與下部件22係分別固定於半模體11、12上鉸鏈對立兩側之外側面。The clamping mechanism 20 of the present invention includes an upper component 21 and a lower component 22, as shown in Figure 3. Figure 3 shows that the upper component 21 and the lower component 22 are parallel to each other. In practice, the upper component 21 and the lower component 22 are fixed to the outer side surfaces of the opposite sides of the hinge on the half mold body 11, 12 respectively.
上部件21及下部件22分別固定於模具10之上半體11及下半體12，設於如圖4所示彼此面對之位置，亦即當二半模體11、12彼此閉合時，上部件21與下部件22彼此接合。The upper component 21 and the lower component 22 are respectively fixed to the upper half 11 and the lower half 12 of the mold 10, and are arranged at positions facing each other as shown in FIG. 4, that is, when the two half molds 11 and 12 are closed to each other, the upper component 21 and the lower component 22 are engaged with each other.
上部件21及下部件22各包含若干基本零件，例如圖5所示之二限位件23及圖6所示之鎖閂24。The upper component 21 and the lower component 22 each include a plurality of basic parts, such as two limiting components 23 shown in FIG. 5 and a locking bolt 24 shown in FIG. 6 .
參見圖6，鎖閂24係呈T形，其兩臂之上方角落形成斜角。於一實際實施例中，鎖閂24包括一主幹241及兩側臂242，且各側臂242具有一下方面243及一斜角面245。該鎖閂24並包括一上方面244，其中，下方面243與上方面244係實質上垂直於主幹241，且斜角面245是自上方面244傾斜約45°。Referring to FIG. 6 , the lock bolt 24 is T-shaped, and the upper corners of its two arms form an oblique angle. In an actual embodiment, the lock bolt 24 includes a main trunk 241 and two side arms 242, and each side arm 242 has a lower surface 243 and an oblique surface 245. The lock bolt 24 also includes an upper surface 244, wherein the lower surface 243 and the upper surface 244 are substantially perpendicular to the main trunk 241, and the oblique surface 245 is inclined at about 45° from the upper surface 244.
如圖5所示，對應於鎖閂24形狀，限位組包括鏡像對稱之限位件23，此二限位件23各具有一凹入段232，且其排列使得二凹入段232共同形成一可緊密包覆鎖閂24T形鎖頭之C形。在一實際實施例中，每一限位件23之向內凹入段232是由下橫部233、直向部237、傾斜部235與上橫部234所構成。As shown in FIG. 5 , corresponding to the shape of the lock bolt 24, the stopper assembly includes mirror-symmetrical stoppers 23, each of the two stoppers 23 having a concave section 232, and the arrangement thereof enables the two concave sections 232 to form a C-shape that can tightly cover the T-shaped lock head of the lock bolt 24. In an actual embodiment, the inward concave section 232 of each stopper 23 is composed of a lower transverse portion 233, a straight portion 237, an inclined portion 235, and an upper transverse portion 234.
如圖4及圖5所示，每一限位件23具有兩端，一端設有通孔230，可供限位件23經一旋轉軸32而裝設於上半體11，且另一端設有孔洞231，供一退鎖柄33安裝於其中。As shown in FIG. 4 and FIG. 5 , each stopper 23 has two ends. One end is provided with a through hole 230 for the stopper 23 to be mounted on the upper body 11 via a rotating shaft 32 , and the other end is provided with a hole 231 for a release handle 33 to be installed therein.
所述旋轉軸32可為一軸桿，經例如焊接或螺鎖等習知結構而固定於上半體11。如圖1所示，旋轉軸32係一固定於半模體之栓件，此栓件之頭部可提供擋止並固定限位件23之功能。限位件23係以可旋轉之方式經由旋轉軸32裝設。為簡化圖面，旋轉軸32及通孔230係以單一個數顯示。The rotating shaft 32 can be a shaft, which is fixed to the upper half 11 by a known structure such as welding or screws. As shown in FIG1 , the rotating shaft 32 is a bolt fixed to the half mold body, and the head of the bolt can provide the function of blocking and fixing the limiter 23. The limiter 23 is installed through the rotating shaft 32 in a rotatable manner. To simplify the drawing, the rotating shaft 32 and the through hole 230 are shown as a single number.
退鎖柄33可為一短柱，其係經習知結構固定於限位件23，所述習知結構例如為焊接與限位件23上螺孔配合之螺栓件，如圖所示。The unlocking handle 33 can be a short column, which is fixed to the limiting member 23 through a known structure, such as a bolt member welded and matched with a screw hole on the limiting member 23, as shown in the figure.
二限位件23並列設置，因此在一實際實施例中，限位件23之上端為斜角，以確保其可圍繞旋轉軸32自由旋轉，如圖5所示。The two limiting members 23 are arranged in parallel, so in an actual embodiment, the upper end of the limiting member 23 is beveled to ensure that it can rotate freely around the rotation axis 32, as shown in FIG. 5 .
於另一實施例中，如圖5所示，限位件23之下方角落亦為斜角，形成一斜角面236。此實施例之優點在於鎖閂24頭部可輕易進入限位組之空間，亦即二限位件23之相鄰空間232所形成之空間。In another embodiment, as shown in FIG5 , the lower corner of the stopper 23 is also beveled to form a beveled surface 236. The advantage of this embodiment is that the head of the latch 24 can easily enter the space of the stopper assembly, that is, the space formed by the adjacent spaces 232 of the two stoppers 23.
本發明之鎖模機構20可經由習知方法固定於模具10，例如焊接、螺鎖，較佳者為利用二兼具旋轉軸32功能之螺栓與螺孔相鎖；亦即每一旋轉軸32構成對應限位件23之偏心主軸。The mold locking mechanism 20 of the present invention can be fixed to the mold 10 by known methods, such as welding and screwing. Preferably, two bolts that also function as rotating shafts 32 are used to lock the bolt holes; that is, each rotating shaft 32 constitutes an eccentric main shaft corresponding to the limiter 23.
本發明之鎖模機構20可直接固定於模具10，亦即鎖閂24及限位組之限位件23可分別直接裝設於二半模體。此實施例之優點為方便製造組裝，然其缺點在於各零件於使用中可能不夠堅固。The clamping mechanism 20 of the present invention can be directly fixed to the mold 10, that is, the locking bolt 24 and the limiting member 23 of the limiting assembly can be directly installed on the two half mold bodies. The advantage of this embodiment is that it is convenient to manufacture and assemble, but its disadvantage is that each component may not be strong enough during use.
因此，在如圖3所示之較佳實施例中，鎖閂24及限位組係分別以第一支撐板25及第二支撐版26為中間物而固定於二半模體，亦即上部件21固定於第一支撐板25，下部件22固定於第二支撐板26。Therefore, in the preferred embodiment shown in FIG. 3 , the lock 24 and the limit assembly are fixed to the two half molds with the first supporting plate 25 and the second supporting plate 26 as intermediate objects, that is, the upper component 21 is fixed to the first supporting plate 25, and the lower component 22 is fixed to the second supporting plate 26.
於如圖7所示之另一較佳實施例中，本發明之鎖模機構20還具有一外擋板27，從外側將限位組保持於定位。In another preferred embodiment as shown in FIG. 7 , the clamping mechanism 20 of the present invention further has an outer baffle plate 27 to hold the limiter assembly in position from the outside.
在又一實施例中，鎖閂24是固定於下半體12，且限位組是固定於上半體11，則本發明鎖模機構20之操作如圖7至圖10所示。In another embodiment, the locking bolt 24 is fixed to the lower body 12, and the stopper assembly is fixed to the upper body 11. The operation of the mold locking mechanism 20 of the present invention is shown in FIGS. 7 to 10.
於圖7及圖9中，二限位件23受外側板27遮擋之部份以虛線顯示。In FIG. 7 and FIG. 9 , the portions of the two stoppers 23 blocked by the outer plates 27 are shown with dotted lines.
圖7描繪具有本發明鎖模機構20鞋底壓形模具之上半體11，以前視圖之角度顯示鎖模機構20處於開啟位置，其中，二限位件23在重力影響下彼此靠攏。由於二限位件23彼此鏡像對稱，且是分別偏心裝設於上半體11與下半體12相鄰之處，此時係以垂直面彼此接觸，因而不致向對方傾倒，故能保持C形以包覆鎖閂24之T形頭部。FIG. 7 depicts the upper half 11 of the sole pressing mold with the clamping mechanism 20 of the present invention, and shows the clamping mechanism 20 in the open position from the front view angle, wherein the two stoppers 23 are against each other under the influence of gravity. Since the two stoppers 23 are mirror-symmetrical to each other and are eccentrically installed at the adjacent parts of the upper half 11 and the lower half 12, they are in contact with each other with vertical planes at this time, so they will not fall to each other, and can maintain the C shape to cover the T-shaped head of the lock 24.
圖8之前視圖描繪具有本發明鎖模機構20之鞋底壓形模具之下半體。如圖所示，鎖閂24係經適當手段固定於第二支撐板26，所述固定手段例如為栓接(如圖中四個中線位於兩側之圓圈)。The front view of Fig. 8 depicts the lower half of the sole pressing mold with the locking mechanism 20 of the present invention. As shown in the figure, the lock 24 is fixed to the second supporting plate 26 by appropriate means, and the fixing means is, for example, bolting (as shown in the figure, the four midlines are located on the circles on both sides).
圖9之前視圖描繪具有本發明鎖模機構20之鞋底壓形模具，其中，鎖模機構20是處於閉合位置。顯然，當模具10如圖7所示開啟時，限位件23之位置與其在如圖9所示模具10閉合時之位置相同。The front view of Fig. 9 depicts a sole pressing mold with the clamping mechanism 20 of the present invention, wherein the clamping mechanism 20 is in a closed position. Obviously, when the mold 10 is opened as shown in Fig. 7, the position of the stopper 23 is the same as when the mold 10 is closed as shown in Fig. 9.
模具10閉合時，在上半體11重量及限位件23與鎖閂24形狀等效應作用下，限位組會自閉合位置移動至開啟位置，而後返回閉合位置，並將鎖閂24穩固定位於其中。When the mold 10 is closed, under the effect of the weight of the upper body 11 and the shapes of the stopper 23 and the lock 24, the stopper assembly moves from the closed position to the open position and then returns to the closed position, and stably fixes the lock 24 therein.
模具10開啟時，退鎖柄33受到促動而彼此遠離，使得二限位件23以相反方向旋轉，因此限位組打開，且在此同時，上半體11向上抬起而與下半體12分離。When the mold 10 is opened, the unlocking handles 33 are actuated to move away from each other, so that the two stoppers 23 rotate in opposite directions, so that the stopper assembly is opened, and at the same time, the upper half 11 is lifted upward and separated from the lower half 12.
圖10所示為圖7之開啟位置移動至圖9之閉合位置或反向移動過程中存在之中間位置。如圖所示，在此中間位置，當鎖閂24之T形鎖頭進入二限位件23之間時，二限位件23是以相反方向偏心旋轉，如以彎曲箭號所表示者。Fig. 10 shows the intermediate position existing in the process of moving from the open position of Fig. 7 to the closed position of Fig. 9 or the reverse movement. As shown in the figure, in this intermediate position, when the T-shaped lock head of the lock bolt 24 enters between the two limit members 23, the two limit members 23 rotate eccentrically in opposite directions, as indicated by the curved arrows.
在鎖閂24受二限位件23緊密固定之情況下，鎖閂24之上方面244及鎖閂24之二側臂242分別受限位件23之凹入段232所固定，且鎖閂24之下方面243擱置於限位件23之下橫部233。鎖閂24及限位件23之形狀結構設計可防止本發明機構自行開啟或鬆動，從而確保模具10之良好操作(亦請參見圖5及圖6)。When the lock bolt 24 is tightly fixed by the two limiting members 23, the upper surface 244 of the lock bolt 24 and the two side arms 242 of the lock bolt 24 are respectively fixed by the concave sections 232 of the limiting members 23, and the lower surface 243 of the lock bolt 24 is placed on the lower horizontal portion 233 of the limiting member 23. The shape and structure design of the lock bolt 24 and the limiting member 23 can prevent the mechanism of the present invention from opening or loosening by itself, thereby ensuring the good operation of the mold 10 (see also Figures 5 and 6).
於另一實施例中，鎖閂24是固定於下半體12而限位組是固定於上半體11，則本發明鎖模機構20之操作如下：In another embodiment, the locking bolt 24 is fixed to the lower half 12 and the stopper assembly is fixed to the upper half 11, and the operation of the mold locking mechanism 20 of the present invention is as follows:
當模具10處於開啟位置，由於限位件23係以可旋轉之方式偏心裝設，其會於自身重量作用下開啟。當上半體11下移而蓋合於下半體12時，鎖閂24進入限位組內之空間，且鎖閂24之上方面244擱置於二限位件23之橫部234，致使限位組閉合並將鎖閂24緊密固定於其中。當模具10開啟時，退鎖柄33受到促動而彼此遠離，致使二限位件23以相反方向旋轉，則限位組打開，在此同時上半體11上抬而與下半體12分離。When the mold 10 is in the open position, since the stopper 23 is eccentrically mounted in a rotatable manner, it will open under its own weight. When the upper half 11 moves down and covers the lower half 12, the lock 24 enters the space in the stopper set, and the upper surface 244 of the lock 24 is placed on the horizontal portion 234 of the two stoppers 23, so that the stopper set is closed and the lock 24 is tightly fixed therein. When the mold 10 is opened, the unlocking handle 33 is actuated to move away from each other, causing the two stoppers 23 to rotate in opposite directions, and the stopper set is opened. At the same time, the upper half 11 is lifted up and separated from the lower half 12.
於實務中，模具10之開啟為自動操作，利用機器手臂推動二退鎖柄33彼此遠離以開啟鎖模機構20，而後將上半體11抬起以開啟模具10。In practice, the mold 10 is opened automatically by using a robot arm to push the two unlocking handles 33 away from each other to open the mold locking mechanism 20, and then the upper body 11 is lifted to open the mold 10.
如上所述，鎖模機構20之閉合僅需閉攏模具10之二半體11、12即可達成。As described above, the closing of the clamping mechanism 20 can be achieved by simply closing the two halves 11 and 12 of the mold 10.
因此，本發明之優點在於可穩固鎖定模具10。並且，當模具10之閉合係採自動化操作時，能夠簡化本發明之鎖模機構20。Therefore, the advantage of the present invention is that the mold 10 can be stably locked. In addition, when the closing of the mold 10 is automated, the mold locking mechanism 20 of the present invention can be simplified.
