Stamping tool

Abstract

A stamping tool for stamping a product having an extending portion includes an upper mold having an inserting punch of which a bottom end defines an inclined pressing surface exposed under the upper mold, and a lower mold including an adjusting element, a sliding block, a returning block, a returning bolt and an elastic element. The returning bolt is inserted in the elastic element, and then screwed in the sliding block through the returning block. The sliding block is slidable between the returning block and the adjusting element and has one corner provided with an inclined abutting surface. The inclined pressing surface presses the abutting surface to push the sliding block and the returning bolt to slide towards the adjusting element so as to make the extending portion clipped between the sliding block and the adjusting element for modulating the product.

1 . A stamping tool for stamping a product which has a base portion and an extending portion extended from a bottom of the base portion, comprising:
 an upper mold including an inserting punch, a bottom end of the inserting punch defining an inclined pressing surface exposed out from a bottom of the upper mold; and   a lower mold including a lower mold plate, a short die pad and a lower modulating mechanism which includes an adjusting element, a sliding block, a modulating piece, a returning block, a returning bolt and an elastic element, the short die pad and the adjusting element being mounted on a top of the lower mold plate and abutting against each other, the returning block being mounted on the top of the lower mold plate apart from the adjusting element, the sliding block being slidably mounted on the top of the lower mold plate between the returning block and the adjusting element, the returning bolt being screwed into the sliding block through the returning block to drive the sliding block to abut against the returning block and be apart from the adjusting element under the action of the elastic element, a top of the sliding block being concaved downward to form a receiving groove opened to face the adjusting element for receiving the modulating piece therein so as to carry the modulating piece to move in on or away from the adjusting element, one corner of the top of the sliding block opposite to the receiving groove being cut off to form an inclined abutting surface matching with the inclined pressing surface;   wherein when the stamping tool is closed, the base portion of the product is positioned between the adjusting element, the modulating piece and the upper mold with the extending portion being suspended between the adjusting element and the modulating piece, and the inclined pressing surface of the inserting punch presses the abutting surface to push the sliding block together with the modulating piece and the returning bolt to slide towards the adjusting element and away from the returning block so as to make the extending portion clipped between the modulating piece and the adjusting element for modulating the product to be a standard shape in the stamping tool.   
     
     
         2 . The stamping tool as claimed in  claim 1 , wherein one end of the modulating piece facing the adjusting element is protruded towards the adjusting element to form an adjusting pin capable of being inserted in the extending portion of the product to position the extending portion between the adjusting element and the modulating piece, when the stamping tool is closed.
