Description

Technical Field

[0001] The utility model relates to the technical field of stamping dies, in particular to a stamping die for stamping parts. Background Art

[0002] Stamping is a forming method that uses a press and a die to apply external force to plates, strips, pipes and profiles to produce plastic deformation or separation, thereby obtaining a workpiece of the desired shape and size. After the stamping is formed, it is generally no longer cut, or only requires a small amount of cutting. With the rapid development of the manufacturing industry, the plates are also using mold processing to improve production efficiency due to the increasing demand. The forming of metal plates is usually achieved by stamping.

[0003] During use, the existing stamping die has a large stamping force. After the stamping is completed, the stamped part will be tightly connected to the lower die, which makes it inconvenient for the user to demould the stamped part. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a stamping die for a stamping part.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a stamping die for stamping parts, comprising a base, a lifting platform is arranged on the upper side of the base, telescopic rods are fixedly installed at the four corners between the lifting platform and the base, a rack is fixedly installed on the front end surface of the lifting platform, a gear is meshed on one side of the rack, a groove is opened inside the base, a rotating shaft is rotatably connected inside the groove, one end of the rotating shaft extends to the outside of the groove and is fixedly connected to the gear, a transmission rod is arranged inside the groove, one end of the transmission rod is fixedly connected to the rotating shaft, a spring is fixedly installed between the lower end surface of the transmission rod and the inner lower end surface of the groove, a limiting plate is arranged on the upper side of the transmission rod, a spring 2 is fixedly installed between the upper end surface of the limiting plate and the inner upper end surface of the groove, a push rod is fixedly installed on the upper end surface of the limiting ring, and the spring 2 is sleeved on the outer surface of the push rod.

[0006] During use, the existing stamping mold has a large stamping force. After the stamping is completed, the stamped part will be tightly connected to the lower mold, which is inconvenient for the user to demold the stamped part. Therefore, the utility model provides a top ring, and uses a telescopic rod to drive the lifting platform to rise while synchronously driving the rack to rise, so that the top ring rises to lift the workpiece, so that the workpiece is separated from the lower mold, and automatic demolding is achieved.

[0007] When the telescopic rod drives the lifting platform to descend, the rack is carried down synchronously, and the gear on the rotating shaft meshes with the rack, and then it rotates.

[0008] Furthermore, an upper mold is fixedly installed on the lower end surface of the lifting platform, and a lower mold is opened on the upper end surface of the base corresponding to the upper mold.

[0009] The rotating shaft rotates counterclockwise and carries the transmission rod to rotate synchronously, and the transmission rod moves away from the top rod.

[0010] Furthermore, a workpiece is arranged inside the lower mold, a top ring is arranged on the lower side of the workpiece, and the top ring is slidably connected to the lower mold.

[0011] The ejector rod will drop under the action of the limit plate and spring 2, so that the workpiece enters the lower mold.

[0012] Furthermore, protrusions are fixedly installed at the four corners of the lower end surface of the base, and the protrusions are made of rubber.

[0013] At this time, the upper die enters the lower die to stamp the workpiece. After the workpiece is stamped, the telescopic rod drives the lifting platform to rise, and the rack rises, thereby causing the rotating shaft to rotate clockwise.

[0014] Furthermore, the ejector rod passes through the groove and extends to the interior of the lower mold, and is fixedly connected to the ejector ring.

[0015] The transmission rod will lift the top rod, and the top rod is fixedly connected to the top ring, thereby driving the top ring to rise.

[0016] Furthermore, the rack, gear, rotating shaft, transmission rod, spring one, spring two, limit plate and push rod are each provided with two groups correspondingly and are symmetrically arranged.

[0017] The top ring rises inside the lower mold, separating the formed workpiece from the lower mold to achieve the function of automatic unloading.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The utility model sets a top ring, and uses a telescopic rod to drive the lifting platform to rise, and then drives the rack to rise synchronously, so that the top ring rises to lift the workpiece, so that the workpiece is separated from the lower mold, and automatic demoulding is achieved.

The rotating shaft 9 rotates counterclockwise and carries the transmission rod 10 to rotate synchronously. The transmission rod 10 will move away from the push rod 13. The push rod 13 will descend under the action of the limit plate 15 and the spring 14, so that the workpiece 6 enters the lower mold 5.

[0031] An upper mold 4 is fixedly mounted on the lower end surface of the lifting platform 3 , and a lower mold 5 is provided on the upper end surface of the base 1 corresponding to the upper mold 4 .

[0032] At this time, the upper mold 4 enters the lower mold 5 to stamp the workpiece 6. After the workpiece 6 is stamped, the telescopic rod 2 drives the lifting platform 3 to rise, and the rack 7 rises, thereby causing the rotating shaft 9 to rotate clockwise.

[0033] A workpiece 6 is disposed inside the lower mold 5 , and a top ring 16 is disposed on the lower side of the workpiece 6 . The top ring 16 is slidably connected to the lower mold 5 .

After the workpiece 6 is stamped and formed, the telescopic rod 2 drives the lifting platform 3 to rise, the rack 7 rises, and then the rotating shaft 9 rotates clockwise, and the transmission rod 10 will lift the ejector rod 13. The ejector rod 13 is fixedly connected to the ejector ring 16, thereby driving the ejector ring 16 to rise. The ejector ring 16 rises inside the lower mold 5, and the formed workpiece 6 is separated from the lower mold 5 to realize the function of automatic unloading.
