It will be understood that when an element is referred to as being "secured to" or "disposed on" another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only and do not represent the only embodiments.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1 to 3, a novel mold stripping device comprises an upper mold 1, a lower mold 2 and a plurality of punches 3, wherein the upper mold 1 is movably mounted on the lower mold 2, a gap is arranged between the upper mold 1 and the lower mold 2, the plurality of punches 3 are mounted on the upper mold 1, a groove 21 is formed in the lower mold 2 corresponding to the punches 3, a spring thimble 31 is arranged in the punches 3 along the vertical direction, and the end of the spring thimble 31 protrudes out of the punches 3 and extends into the groove 21. Specifically, during the use, sheet 100 is placed in the clearance between upper die 1 and lower die 2, sheet 100 can be sheet metal, or plastic piece etc. and external drive device, for example the pneumatic cylinder, drives upper die 1 and moves from top to bottom, drives drift 3 and draws close lower die 2 when, is the punching press promptly. During punching, the punch 3 is pressed down along with the upper die 1, vertically acts on the sheet 100, and is matched with the lower die 2 provided with the groove 21, so that a required product 101 can be punched on the sheet 100 at the position of the groove 21. In order to prevent the punched product 101 from being adhered to the end of the punch 3, a plurality of spring ejector pins 31 are arranged in the punch 3, when the punch 3 acts on the surface of the sheet 100, the spring ejector pins 31 are extruded by the sheet 100 and retract into the punch 3, and after the punch 3 is separated from the sheet 100 after punching is finished, the spring ejector pins 31 return, so that the product 101 can be pushed down from the end surface of the punch 3, the product 101 is prevented from being sleeved on the punch 3, the product 101 is prevented from being scrapped, and the yield is reduced.

As shown in fig. 1 to 3, the punch 3 is provided with a spring thimble seat 32 along the punching direction, the spring thimble 31 is installed in the spring thimble seat 32, and the length of the spring thimble seat 32 is smaller than that of the punch 3. Specifically, install spring thimble 31 in spring thimble seat 32, and spring thimble seat 32 tensile length is less than the length of drift 3, avoids when the blanking, and stamping pressure is big, and at this moment, 3 ends of drift reserve the hole for spring thimble 31, and direct action is on product 101 face, and this hole department leaves the vestige on product 101 face easily, leads to the product yields to descend.

As shown in fig. 1 to 2, a discharge chute 22 is provided below the lower mold 2, and an upper end of the discharge chute 22 abuts against an end of the shaping groove 21. Specifically, the discharge chute 22 is a chute made of stainless steel, and the upper end of the discharge chute is abutted to the end opening of the type groove 21, so that a product which is punched completely falls into the discharge chute 22 along the type groove 21 and is collected.

As shown in fig. 1 to 2, the lower mold 2 is mounted on a base 4, and the discharge chute 22 is mounted in the base 4. Specifically, fretwork between lower mould 2 and base 4 for place the blown down tank 22 of slope, and make lower mould 2 unsettled, the product 101 of blanking can directly fall into blown down tank 22 from type groove 21 in, and then the landing comes out, accomplishes and collects.

As shown in fig. 1 to 3, a plurality of guide posts 23 are arranged on the side portion of the lower die 2, the side portion of the upper die 2 is movably connected with the guide posts 23, and when an external hydraulic cylinder or other driving components drive the upper die 1 to move up and down, the guide posts 23 play a role in guiding, so that the upper die 1 and the lower die 2 are prevented from being misplaced, which results in a mistake in the shape groove 21 on the punch 3 and the lower die 2, which results in a misplacement in punching and cutting, and a product is scrapped.

As shown in fig. 2 to 3, a punch holder 11 is provided on a side of the upper die 1 facing the lower die 2, and the punch 3 is detachably connected to the punch holder 11 by a bolt. Specifically, the punch bases 11 are used for disassembling and assembling punches 3 in various shapes, the corresponding lower dies 2 are matched, workpieces in different shapes are punched and cut, and the applicability is better. Knoing, during installation spring thimble 31, can utilize the power of leaning on of punch holder 11 with the tip and the 11 butt of punch holder of spring thimble 31, push away product 101 and when spring thimble 31 damages, can change simple and convenient after dismantling drift 3.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
