Description

復動式夾模器Double Action Clamp

本發明係一種復動式夾模器，尤指使用油壓將夾模復位之夾模器。 The present invention relates to a double-action mold clamp, especially a mold clamp that uses oil pressure to reset the clamp mold.

查，習知夾模器結構，大致如第一圖所示，係一固定座1、一套筒2組設於該固定座1，一活塞3設於該套筒2內，該活塞3上方具有一凸桿4，套設有一復位彈簧5，該活塞3下方為油壓室6。當下方油壓室6充滿液壓油時，可將該活塞3頂推，使該凸桿4凸出於該套筒2，即可具有夾力；當液壓油回油時，該復位彈簧5會協助將該活塞3復位。 Check, the conventional clamping device structure, as shown in the first figure, is a fixed base 1, a sleeve 2 set in the fixed base 1, a piston 3 is set in the sleeve 2, above the piston 3 There is a protruding rod 4 , a return spring 5 is sleeved, and the lower part of the piston 3 is an oil pressure chamber 6 . When the lower oil pressure chamber 6 is full of hydraulic oil, the piston 3 can be pushed up to make the protruding rod 4 protrude from the sleeve 2, which can have a clamping force; when the hydraulic oil returns to the oil, the return spring 5 will Assist in resetting the piston 3.

若要轉變夾力方向，可再有一凸座7連設於該固定座1，該凸座7上樞接一夾定塊8，該夾定塊8之一端可被該凸桿4頂推，該夾定塊8之另一端即可轉換夾力方向。但上述之結構，其實存在有下列缺點： To change the direction of the clamping force, another boss 7 can be connected to the fixing base 1 , and a clamping block 8 is pivotally connected to the boss 7 , and one end of the clamping block 8 can be pushed by the protruding rod 4 . The other end of the clamping block 8 can change the direction of clamping force. However, the above structure actually has the following disadvantages:

(1)習知夾模器凸桿4與套筒2之間並無密封，導致空氣、水氣皆會由此縫隙進入內部，使得凸桿4、彈簧5等部位容易生鏽，而灰塵、加工碎屑亦可能堵住隙縫，增加凸桿4伸縮時的摩擦力，使得凸桿4的復位速度降低。 (1) There is no seal between the protruding rod 4 of the conventional clamp and the sleeve 2, which causes air and moisture to enter the interior through this gap, making the protruding rod 4, spring 5 and other parts easy to rust, and dust, Machining debris may also block the gap, increase the frictional force when the protruding rod 4 is stretched, and reduce the return speed of the protruding rod 4 .

(2)當欲鬆弛習知夾模器時，主要是靠復位彈簧5的彈力與活塞3本身重量產生的重力，將油壓室6的液壓油推回，使活塞3復位，讓凸桿4縮回套筒2內。然而彈力與重力的力道相對於油壓室6的壓力來說較小，使得活塞3的復位速度較慢，且當長久使用後，彈簧5可能會彈性疲乏，更降低復位速度。讓夾模器的變鬆弛狀態的時間延長，無法快速更換模具物件。 (2) When the conventional clamp is to be loosened, it mainly relies on the elastic force of the return spring 5 and the gravity generated by the weight of the piston 3 to push the hydraulic oil in the hydraulic chamber 6 back, so that the piston 3 is reset, and the protruding rod 4 is reset. Retract into sleeve 2. However, the force of the elastic force and gravity is smaller than the pressure of the oil pressure chamber 6, which makes the return speed of the piston 3 slow, and after long-term use, the spring 5 may be elastically fatigued, which further reduces the return speed. The time for the clamp to be in a relaxed state is prolonged, and it is not possible to quickly change the mold object.

(3)習知夾定塊8的前方是設計為直角，當夾定塊8下壓時，夾定塊8的夾持點會往內縮，使與模具物件W的邊緣距離變小，容易造成模具物件W變形，並且容易使得夾定塊8從模具上滑脫，無法穩定使用。 (3) The front of the conventional clamping block 8 is designed as a right angle. When the clamping block 8 is pressed down, the clamping point of the clamping block 8 will shrink inwards, so that the distance from the edge of the mold object W becomes smaller, which is easy to The mold object W is deformed, and the clamping block 8 is easily slipped off the mold, which cannot be used stably.

本發明即是為改良上述習知之缺點，主要技術、目的為：設計一種以油壓復動之夾模器，係包含：一固定座具有一容置空間；一活塞具有凸桿設於該容置空間，將該容置空間分成第一及第二油壓室；一止逆閥組設於該固定座；一第一油壓輸入孔，組設於該固定座，當液壓油從該第一油壓輸入孔輸入時，該液壓油會先經過該止逆閥，再進入該第一油壓室，可將該活塞頂推，使該凸桿凸出產生夾力；一第二油壓輸入孔，組設於該固定座，當液壓油從該第二油壓輸入孔輸入時，該液壓油會打開該止逆閥，並進入該第二油壓室，使得第一油壓室的液壓油可延著逆止閥從原管路回油。如此本發明復動式夾模器可藉由液壓使活塞復位，達到可快速鬆弛夾具的功效。 The present invention is to improve the above-mentioned shortcomings of the prior art. The main technology and purpose of the present invention are: to design a mold clamping device that is double-moved by oil pressure, which includes: a fixed seat has an accommodating space; a piston has a protruding rod disposed in the accommodating space The accommodating space is divided into first and second oil pressure chambers; a check valve group is arranged on the fixed seat; a first oil pressure input hole is arranged on the fixed seat, when the hydraulic oil flows from the first oil pressure chamber When an oil pressure input hole is input, the hydraulic oil will first pass through the non-return valve, and then enter the first oil pressure chamber, which can push the piston to make the protruding rod protrude to generate clamping force; a second oil pressure The input hole is set on the fixed seat. When hydraulic oil is input from the second oil pressure input hole, the hydraulic oil will open the check valve and enter the second oil pressure chamber, so that the first oil pressure chamber The hydraulic oil can be returned to the oil from the original pipeline along the check valve. In this way, the double-action die clamp of the present invention can reset the piston by hydraulic pressure, so as to achieve the effect of rapidly loosening the clamp.
