[0032] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part rather than all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Referring to Figures 1 to 8 , this embodiment provides an automatic blank unloading mechanism in a stamping die, including: a jacking cylinder 100, a stock supporting assembly 200, a limiting assembly 300, and a buffer member 400.

[0034] The jacking cylinder 100 is vertically and fixedly installed in the die body 500, and the piston rod of the jacking cylinder 100 can jack up upward.

[0035] The blank supporting assembly 200 includes a first connecting plate 210, a second connecting plate 220, and a blank supporting member 230. The first connecting plate 210 is fixedly connected to the piston rod of the lifting cylinder 100. The approximate middle position of the second connecting plate 220 is hingedly connected to one end of the first connecting plate 210. The blank supporting member 230 is disposed above the second connecting plate 220, and the blank supporting member 230 is formed to conform to the workpiece.

[0036] The limiting assembly 300 includes a guide rod 310 and a limiting member 320. The guide rod 310 vertically and slidably passes through the mold body 500 and enters the cavity 510 below the mold body. The top end of the guide rod 310 is hingedly connected to a strip-shaped hole 221 provided at one end of the second connecting plate 220 and extending along its length direction through a mandrel. The limiting member 320 is disposed at the bottom of the guide rod 310. The limiting member 320 is located in the cavity 510 below the mold body 500 and cannot pass through the cavity 510. Through the cooperation of the limiting member 320 and the mold body 500, the upward sliding stroke of the guide rod 310 in the mold body 500 can be limited.

[0037] In this embodiment, a nut is used as the limiting member 320, which is in threaded engagement with the guide rod 310, so that the height position of the limiting member 320 on the guide rod 310 can be adjusted, and further the upward sliding stroke of the guide rod 310 can be adjusted.

[0038] The buffer member 400 is installed on the mold body 500. In this embodiment, a polyurethane block is used as the buffer member 400. When the end of the blank supporting assembly 200 away from the limiting assembly 300 drops, the second connecting plate 220 of the blank supporting assembly 200 contacts the buffer member 400, playing a buffering role.

[0039] The working principle of an automatic part discharging mechanism in a stamping die provided in this embodiment:

[0040] In the initial state, the piston rod of the lifting cylinder 100 is in the retracted state, and the material supporting assembly 200 is in the horizontal state; when the workpiece 600 is stamped in the mold, the workpiece 600 falls on the material supporting member 230; at this time, the piston rod of the lifting cylinder 100 jacks up, driving the first connecting plate 210 together with the second connecting plate 220, the material supporting member 230 and the limiting assembly 300 to move upward together. When the limiting member 320 of the limiting assembly 300 reaches the limiting position, the guide rod 310 and the limiting member 320 stop moving upward, and the piston rod of the lifting cylinder 100 continues to jack up. The second connecting plate 220 rotates around the hinge point with the guide rod 310, and the first connecting plate 210 rotates around the hinge point with the second connecting plate 220 until the jacking stroke of the piston rod of the lifting cylinder 100 ends. At this time, the material supporting member 230 is in an inclined state, and the workpiece 600 falling on the material supporting member 230 slides off automatically, completing the unloading of the workpiece.
