[0036] The present invention realizes the function of controlling the separation of the raised part of the workpiece 6 from the lower die through the frame 1, the discharge device 2 and the lifting control mechanism 3, so as to achieve the effect of stably controlling the unloading of the workpiece 6. After the stamping process of the workpiece 6 is completed, the workpiece 6 is lifted up by the rise of the movable seat 21, so that the raised part of the workpiece 6 is separated from the die, and the problem that the raised part of the workpiece 6 is combined with the cavity and affects the unloading of the workpiece 6 is solved. The frame 1 is provided with a hydraulic system for controlling the lifting and lowering of the mounting seat 12 for stamping. During the processing, the mounting seat 12 is controlled to move downward by the hydraulic system, and the mounting seat 12 drives the upper die of the first die group 13, the second die group 14 and the third die group 15 to move downward for stamping. After completing one processing, the material belt 5 is controlled to move again, and the stamping process is performed again. The processed part on the material belt 5 completes the stamping process after three processing. During the stamping process, the mounting seat 12 drives the lifting control mechanism 3 when it moves downward, and the lifting control mechanism 3 controls the movable seat 21 to move downward, and at the same time, the workpiece 6 is stamped through the cavity of the third mold group 15. After the stamping is completed, the mounting seat 12 moves up and drives the bottom rod 22 to move up through the lifting control mechanism 3. The bottom rod 22 drives the movable seat 21 to move up through the reset elastic member 221, and pushes the workpiece 6 up through the movable seat 21, so that the workpiece 6 moves to a position at the same height as the material belt 5, and then the workpiece 6 is pushed to move by the movement of the material belt 5, and the workpiece 6 is moved to the unloading slide of the frame 1 to complete the processing and unloading of the workpiece 6.

[0037] Reference Figure 3-Figure 5 : The lifting control mechanism 3 includes a downward pressing connection seat 31, a movable connection seat 32 and a clamping assembly 33; the downward pressing connection seat 31 is connected to the mounting seat 12; the movable connection seat 32 is movably arranged on the base 11, and the movable connection seat 32 is connected to the bottom rod 22, a slot is provided on the movable connection seat 32, and a protrusion for plugging into the slot is provided on the downward pressing connection seat 31; the clamping assembly 33 is arranged on the movable connection seat 32, and when the downward pressing connection seat 31 is plugged into and matched with the movable connection seat 32, the clamping assembly 33 connects the downward pressing connection seat 31 and the movable connection seat 32.

[0038] The present invention realizes the function of controlling the lifting and lowering of the movable seat 21 by lifting and lowering the mounting seat 12 through the pressing connecting seat 31, the movable connecting seat 32 and the clamping assembly 33. After the pressing action is completed, the movable connecting seat 32 is pulled upward by the pressing connecting seat 31 and the clamping assembly 33, and then the movable connecting seat 32 drives the bottom rod 22 to pull the movable seat 21 to move. During the stamping process, when the mounting seat 12 moves downward, the pressing connecting seat 31 is driven downward, and when the protrusion of the pressing connecting seat 31 is plugged into the slot on the movable connecting seat 32, the clamping assembly 33 connects the pressing connecting seat 31 and the movable connecting seat 32. After the pressing process is completed, the hydraulic system controls the mounting seat 12 to reset, the mounting seat 12 drives the pressing connecting seat 31 and the movable connecting seat 32 to move upward, the movable connecting seat 32 drives the bottom rod 22 to move upward, the bottom rod 22 drives the movable seat 21 to move upward through the first elastic member 333, and the workpiece 6 is pushed upward through the movable seat 21. During the upward movement of the workpiece 6, the bottom rod 22 is restricted by the base 11 and stops moving. As the tension between the downward connecting seat 31 and the movable connecting seat 32 increases, the clamping assembly 33 disconnects the connection between the downward connecting seat 31 and the movable connecting seat 32, and the movable seat 21 stops moving. The workpiece 6 moves to a position at the same height as the material belt 5, and then the workpiece 6 is pushed to move by the movement of the material belt 5, and the workpiece 6 is moved to the unloading slide of the frame 1 to complete the processing and unloading of the workpiece 6.

[0039] Reference Figure 4-Figure 7 When the cam 312 is in the unlock state, the cam 314 is in the unlock state, and the lock 316 is in the unlock state, so that the cam 316 is unlocked and the lock 316 is locked.

[0040] The present invention realizes the function of connecting the pressing connection seat 31 and the movable connection seat 32 through the extension rod 311 , the support 312 , the first clamping block 331 , the second clamping block 332 , the first elastic member 333 and the second elastic member 334 . When the support 312 contacts the first clamping block 331 and the second clamping block 332, the first clamping block 331 and the second clamping block 332 are squeezed. When the support 312 passes over the first clamping block 331 and the second clamping block 332, the first clamping block 331 and the second clamping block 332 are respectively popped out under the elastic force of the first elastic member 333 and the second elastic member 334. After the first clamping block 331 and the second clamping block 332 abut against the support 312, the movement of the support 312 is restricted to prevent the support 312 from separating from the movable connecting seat 32, thereby completing the connection between the press-down connecting seat 31 and the movable connecting seat 32. After the pressing process is completed, the hydraulic system controls the mounting seat 12 to reset, and the mounting seat 12 drives the pressing connecting seat 31 and the movable connecting seat 32 to move upward, and the movable inner left drives the bottom rod 22 to move upward, and the bottom rod 22 drives the movable seat 21 to move upward through the first elastic member 333, and pushes the workpiece 6 to move upward through the movable seat 21, so that the raised part of the workpiece 6 is separated from the cavity.

[0041] Reference Figure 3 and Figure 6 : The movable connecting seat 32 is provided with a limiting component 34 for limiting the movement of the first block 331 or the second block 332; the movable connecting seat 32 is also provided with a control component 35 for switching the limiting component 34 on the first block 331 or the second block 332; the support 312 is slidably matched with the extension rod 311; in the working state, when the limiting component 34 limits the movement of the first block 331, the second block 332 is in a free state.

[0042] The present invention realizes the movement restriction of the first block 331 and the second block 332 during the installation and pressing process respectively through the restriction component 34 and the control component 35. During the downward movement of the mounting seat 12, the mounting seat 12 drives the pressing connection seat 31 to move, and the pressing connection seat 31 drives the extension rod 311 and the support 312 to move. When the support 312 contacts the first block 331 and the second block 332, the restriction component 34 restricts the movement of the first block 331, so that the first block 331 will not shrink due to the squeezing effect of the support 312. After the second block 332 is squeezed by the support 312, the second elastic member 334 shrinks under the squeezing force, thereby causing the second block 332 to shrink to the movable connection seat 32. After the support 312 passes over the second block 332, the second block 332 pops out under the elastic force of the second elastic member 334, thereby limiting the support 312 from separating from the movable connection seat 32 through the second block 332. When the mounting base 12 moves upward, the movable connecting base 32 is pulled to move by pressing down the connecting base 31. When the movement of the movable connecting base 32 and the bottom rod 22 is restricted, the restriction object of the restriction component 34 is switched by the control component 35, so that the restriction component 34 restricts the movement of the second clamping block 332 and releases the restriction on the movement of the first clamping block 331. The support 312 squeezes the first clamping block 331 under the action of the pulling force, and then overcomes the elastic force of the first elastic member 333 through the extrusion force to push the first clamping block 331 until the support 312 is separated from the first clamping block 331, completing the separation of the pressing down connecting base 31 and the movable connecting base 32.

[0043] Reference Figure 4-Figure 7 : The limiting assembly 34 includes a limiting rod 341 and a connecting rod 343; there are two limiting rods 341, which can be raised and lowered on the movable connection seat 32, and the two limiting rods 341 are respectively located at the first block 331 and the second block 332; an articulated seat 342 is provided at the end of the limiting rod 341, and a first shaft 3421 is provided on the articulated seat 342; the connecting rod 343 is rotatably arranged on the movable connection seat 32, and two sliding grooves are provided on the connecting rod 343, and the first shafts 3421 on the two articulated seats 342 are respectively slidably hinged to the two sliding grooves of the connecting rod 343.

[0044] The present invention realizes the function of releasing the restriction on the second clamping block 332 when restricting the movement of the first clamping block 331 through the limiting rod 341, the hinge seat 342, the first shaft 3421 and the connecting rod 343. When the control component 35 controls the connecting rod 343 to rotate, the connecting rod 343 pulls or pushes the first shaft 3421 on the hinge seat 342 of the two limiting rods 341, thereby controlling the two limiting rods 341 to slide, and when one limiting rod 341 moves downward, the other limiting rod 341 is driven to move upward. When the limiting rod 341 abuts against the first clamping block 331 or the second clamping block 332, the first clamping block 331 or the second clamping block 332 is restricted from shrinking through the supporting effect of the limiting rod 341. In addition, the switching restriction of the first clamping block 331 and the second clamping block 332 is realized through the transmission effect of the connecting rod 343.

[0045] Reference Figure 6 and Figure 8 : The control component 35 includes a push rod 351 and a third elastic member 352; the push rod 351 is arranged on the downward pressure connecting seat 31 so as to be able to be raised and lowered; the connecting rod 343 is connected to the movable connecting seat 32 through a torsion spring, and a second shaft member 3431 is arranged on the connecting rod 343, and the axis of the second shaft member 3431 deviates from the connection point between the connecting rod 343 and the movable connecting seat 32; the two ends of the third elastic member 352 are respectively connected to the push rod 351 and the downward pressure connecting seat 31.

[0046] The present invention realizes the movement control function of the push rod 351 through the push rod 351 and the third elastic member 352. When the mounting seat 12 moves downward, it drives the downward pressing connecting seat 31 to move, and the downward pressing connecting seat 31 drives the push rod 351 to move through the third elastic member 352. After the push rod 351 contacts the second shaft member 3431, it pushes the second shaft member 3431, and then drives the connecting rod 343 to rotate. During the upward movement of the mounting seat 12, as the push rod 351 and the second shaft member 3431 are gradually separated, under the elastic force of the third elastic member 352, the push rod 351 tries to maintain contact with the second shaft member 3431 until the push rod 351 and the second shaft member 3431 are completely separated.

[0047] Reference Figure 6 , Fig. 9 and Fig.10: The movable connecting seat 32 is provided with a guiding mechanism 4 for guiding the support 312 to slide, and the guiding mechanism 4 includes a fourth elastic member 41 and a guide block 42; the two ends of the fourth elastic member 41 are respectively connected to the movable connecting seat 32 and the guide block 42; the guide block 42 is provided with an inclined surface 421, the support 312 is provided with a third shaft member 3121, and the support 312 is provided with a fifth elastic member 3122 for controlling the reset of the support 312, and the two ends of the fifth elastic member 3122 are respectively connected to the support 312 and the downward connection seat 31; during the downward movement of the mounting seat 12, when the third shaft member 3121 on the support 312 contacts the inclined surface 421 of the guide block 42, the guide block 42 is squeezed.

[0048] The present invention realizes the function of guiding the support 312 to slide through the fourth elastic member 41, the guide block 42 and the third shaft member 3121. The fourth elastic member 41 is preferably a compression spring with a damping rod. During the downward movement of the mounting seat 12, when the third shaft member 3121 on the support 312 contacts the inclined surface 421 of the guide block 42, the guide block 42 is squeezed, and the fourth elastic member 41 is squeezed and shrinks. When the support 312 is separated from the inclined surface 421 of the guide block 42, the guide block 42 applies pressure to the support 312 under the elastic force of the fourth elastic member 41, and the fifth elastic member 3122 shrinks under the pressure. At the same time, the support 312 slides the second block 332 through its internal structure or connecting parts under the pressure, so that the support 312 can smoothly pass through the second block 332, and after passing, the second block 332 is reset under the elastic force, thereby limiting the further separation of the support 312 and the downward pressing connection seat 31.

[0049] Reference Fig. 9 and Fig.10 : A raised guide strip 422 is provided on the guide block 42; a support plate 43 is mounted on the movable connection seat 32, and the guide strip 422 on the guide block 42 slides with the support plate 43.

[0050] The present invention realizes the function of guiding the movement of the guide block 42 through the guide bar 422 and the support plate 43. In order to ensure that the guide block 42 can move in the horizontal direction, a thrust in a fixed direction is applied to the support 312, and the support plate 43 and the guide bar 422 are provided. The movement of the guide block 42 is guided by the sliding cooperation between the guide bar 422 on the guide block 42 and the support plate 43, and sufficient supporting force is provided by the support block, so that the guide block 42 can stably push the support 312 to move.

[0051] Reference Figure 6 , Fig.10 and Fig.11: A first oblique notch is provided on the support 312; a second oblique notch is provided on both the first block 331 and the second block 332; in the working state, when the mounting seat 12 drives the downward pressing connecting seat 31 to move downward, when the support 312 passes over the second block 332 and is squeezed by the second block 332, the first oblique notch of the support 312 abuts against the second oblique notch of the first block 331.

[0052] The present invention realizes the function of guiding the movement of the support 312 through the first oblique notch and the second oblique notch. The second oblique notch of the first clamping block 331 and the second oblique notch of the second clamping block 332 arranged on the same movable connection seat 32 are in opposite directions. After the support 312 passes over the second clamping block 332, the second clamping block 332 is reset under the elastic force of the second elastic member 334, and then the elastic force overcomes the elastic force of the fifth elastic member 3122 to push the support 312 to move, and the support 312 approaches the second clamping block 332 and abuts against the second clamping block 332, so that the second oblique notch and the first oblique notch are aligned. The first clamping block 331 is restricted by the limiting component 34 and cannot move, and then the movable connecting seat 32 is pulled to move by pressing down the connecting seat 31. Since the thrust required for demolding the workpiece 6 is not large, the second clamping block 332 will not be driven to shrink. When the movement of the bottom rod 22 is restricted, the movement of the first clamping block 331 is no longer restricted, and the support 312 can squeeze the first oblique notch on the first clamping block 331, so that the first clamping block 331 shrinks, and then the support 312 is separated from the movable connecting seat 32.
