Description

Technical Field

[0001] The utility model relates to the technical field of stamping forming devices, in particular to a rolling discharging device for a mold. Background Art

[0002] A stamping die is a special process equipment used to process metal or non-metallic materials into parts or semi-finished products in a cold stamping process. Stamping is a pressure processing method in which a die installed on a press is used to apply pressure to the material at room temperature to separate or plastically deform the material, thereby obtaining the desired parts. In order to improve the forming efficiency of parts, continuous dies are usually used for forming. For example, Chinese Patent 202220897075.4 discloses a continuous forming stamping die, including a frame, a lower die is arranged on the frame, an upper die is lifted and arranged on the frame, and is located above the lower die, forming a stamping space between the upper die and the lower die, and after the upper die is lifted and lowered, the upper die moves away from or approaches the lower die, and also includes a material conveying assembly arranged on one side of the frame, wherein the lower die has a first stamping through hole, a forming through hole, and a trimming through hole.

[0003] When the continuous mold is used to form the parts, the parts are usually cut and unloaded through the blanking hole or the inclined unloading track. The fixed unloading hole is not conducive to the arrangement of the receiving box to collect the parts, and when the inclined unloading track is used to realize the unloading of parts, the fixed angle unloading track is difficult to adjust the unloading speed of the parts to meet the requirements. If the unloading track is tilted too much, the parts will slide down quickly and the parts will be easily damaged by collision. If the unloading track is tilted too little, the parts will not slide down smoothly and the parts will accumulate in the unloading track, affecting the unloading efficiency. Utility Model Content

The surface of the blanking plate 231 is provided with a plurality of guide rollers 233 arranged along its length direction.

[0032] A push rod 24 is disposed on the back of the floating seat 23 . The push rod 24 is elastically connected to the lower die seat 21 . The end of the push rod 24 contacts the floating seat 23 , thereby realizing an elastic connection of the floating seat 23 .

[0033] A guide rod 25 is also provided on the back of the floating seat 23. An end plate 251 is provided at one end of the guide rod 25. The diameter of the end plate 251 is larger than the diameter of the guide rod 25. A guide groove 211 corresponding to the position of the end plate 251 is provided on the lower die seat 21. The end plate 251 is slidably connected in the guide groove 211. A pressing block 212 is provided at the end of the guide groove 211. The guide rod 25 is inserted into the pressing block 212. When the floating seat 23 is lifted upward by the ejector rod 24, the guide rod 25 assists in controlling the rising height of the floating seat 23. The guide rod 25 can pass through the pressing block 212, but the diameter of the end plate 251 is larger than the diameter of the guide rod 25, and the end plate 251 is blocked by the pressing block 212.

[0034] Two parallel guide rods 25 are also provided on the back of the floating seat 23 . The two guide rods 25 are symmetrically arranged on both sides of the top rod 24 , so as to further make the floating seat 23 move smoothly.

[0035] The end of the guide rod 25 is threadedly connected to the threaded hole 235 on the housing of the floating seat 23, which is convenient for adjusting the length of the guide rod 25 extending into the floating seat 23, thereby accurately adjusting the rising distance of the floating seat 23 in the free state, which is convenient for parts unloading.

[0037] Working principle: When the upper mold mechanism and the lower mold mechanism 2 are closed, the stripper plate 1 first squeezes the material strip on the surface of the floating seat 23 and the floating seat 23 downward, and the edge of the material strip is stuck in the groove on the side of the floating pin 22. After the material strip is attached to the lower mold surface of the lower mold mechanism 2, the upper punch 11 punches out the connection between the molded part and the material strip at the floating seat 23, and the part is separated from the material strip. When the mold is separated later, the floating pin 22 cooperates with the floating seat 23 to drive the material strip to rise, and the part is discharged along the guide roller 233 on the unloading plate 231 under the action of gravity. The unloading plate 231 can control the inclination angle of the unloading plate 231 by rotating the rotating shaft of the driving motor 232, thereby controlling the falling speed of the part. At the same time, the guide roller 233 of different materials can be further replaced to change the friction between it and the part, further control the falling speed of the part, and solve the problem of uncontrollable unloading speed of the part in the inclined unloading track.
