Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a stamping mold for a flip cover of a wall-mounted boiler. Background Art

[0002] A stamping die is a commonly used cold working die, a special process equipment for processing sheet metal into parts. It uses a die installed on a punch press to apply pressure to the sheet metal to cause it to separate or plastically deform, thereby obtaining a pressure processing method for the required parts. When stamping sheet metal parts, traditional stamping dies need to position the stamped sheet metal and clamp it with a fixture, but this method makes it somewhat troublesome to load the sheet metal onto the machine and has low production efficiency. Therefore, the die structure needs to be improved according to the structural characteristics of the sheet metal parts. Summary of the Invention

[0003] In order to overcome the shortcomings of the background technology, the technical solution adopted by the utility model is: a stamping die for the flip cover of a wall-mounted boiler, comprising an upper die base, an upper pad, an upper pressure plate, a spring, a first punch part, a second punch part, a lower pad, a lower die base, a first stamping seat and a second stamping seat, the upper die base is fixedly connected to the upper pad, the upper die base is slidably connected to the upper pressure plate for fixing the workpiece, and a spring for resetting is provided between the upper pressure plate and the upper die base, the upper die base and the upper pad are respectively connected to the second punch part and the first punch part for stamping, the outer contour of the lower die base is rectangular, the lower die base is fixedly connected to the lower pad, and the lower pad is clamped with the first stamping seat and the second stamping seat corresponding to the first punch part and the second punch part.

[0004] By adopting the above technical solution, when the punch press controls the upper die seat to press down, the flip cover is pressed tightly against the lower pad and positioned through the upper pressure plate, and the upper die seat continues to press down. At this time, the first punch piece and the second punch piece on the upper pad pass through the upper pressure plate to punch out the flip cover, wherein the first punch piece and the first punch seat are combined to punch out the display screen slot, and the second punch piece and the second punch seat are combined to punch out the speaker slot; the flip cover of the wall-mounted boiler is generally in the shape of a rectangular box, and the outer contour of the lower die seat is the same as the inner cavity contour of the flip cover, so that the flip cover can be directly mounted on the lower die seat and positioned without the need for other positioning structures, with low manufacturing costs and avoiding damage to the flip cover surface by the fixture.

[0005] The utility model is further configured such that the first punch member is provided with first guide post holes distributed symmetrically, and the first stamping seat and the lower die seat are provided with second guide post holes and third guide post holes distributed coaxially with the first guide post holes.

[0006] Using the above technical solution, during installation, the screws of the lower pad and the lower die base are pre-tightened, and the two guide pillars are passed through the first guide pillar hole, the second guide pillar hole and the third guide pillar hole, so that the first punch part, the first punching seat and the lower die base are aligned, and then the corresponding mounting screws are tightened, thereby improving the processing accuracy and making the bending parts of the stamped sheet metal parts neat and the thickness uniform.

[0007] The utility model is further configured such that the first punching seat and the second punching seat are respectively provided with a first floating lift pin hole and a second floating lift pin hole distributed in a circumference, and the lower die seat is provided with a first spring hole and a second spring hole corresponding to the first floating lift pin hole and the second floating lift pin hole.

[0008] With the above technical solution, when the first punch and the second punch punch the sheet metal part, the lifting pin is compressed. After the punching is completed, the lifting pin pushes out the punched waste material to facilitate the cleaning of the processing waste material.

[0009] The utility model is further configured as follows: the upper pad is provided with a first threaded hole and a first through hole distributed in a rectangular shape; the upper pressure plate is provided with a slide groove and a second through hole; one side of the first punch part is connected to the upper pad through the first threaded hole, and the other side is slidably connected to the slide groove; the upper die base is provided with a second threaded hole; one side of the second punch part is connected to the upper die base through the second threaded hole, and the other side is slidably connected to the second through hole through the first through hole.

[0010] Furthermore, the upper die base is provided with multiple groups of blind holes, the upper pad is provided with third through holes corresponding to the blind holes, one end of the spring is sleeved in the blind hole, and the other end passes through the third through hole and abuts against the upper pressure plate.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] 1. When the punch press controls the upper die seat to press down, the upper pressing plate presses the flip cover tightly against the lower pad and positions it. The upper die seat continues to press down. At this time, the first punch and the second punch on the upper pad pass through the upper pressing plate to punch the flip cover. The first punch and the first punch seat combine to punch out the display screen slot, and the second punch and the second punch seat combine to punch out the speaker slot.

[0013] 2. The flap of the wall-mounted boiler is in the shape of a rectangular box. The outer contour of the lower mold base is the same as the inner contour of the flap, so that the flap can be directly mounted on the lower mold base and positioned without the need for other positioning structures. The manufacturing cost is low and the fixture is prevented from damaging the flap surface.
