[0029] The following are specific embodiments of the present invention, and the technical solution of the present invention will be further described in conjunction with the accompanying drawings.

[0030] like Figure 1-5 As shown, a probe stamping die includes: an upper die base 1 and a lower die base 5, with a guide post 3 and a first spring 2 arranged sequentially between the upper die base 1 and the lower die base 5, the first spring 2 being wrapped around the guide post 3;

[0031] The lower mold base 5 includes a forming plate 52. A material conveying turntable 4 is provided on one side of the forming plate 52, and a transmission unit 44 for driving the material conveying turntable 4 to rotate is provided on the other side. The material conveying turntable 4 is provided with a feeding end 401 and a discharging end 402 respectively. The feeding end 401 is located outside the forming plate 52.

[0032] The forming plate 52 is provided with a feeding cylinder 46 that cooperates with the feeding turntable 4. The feeding cylinder 46 is located at the feeding end 402.

[0033] The stamping plate 7 is disposed on the guide post 3, and the stamping plate 7 is provided with a stamping block 73 facing the unloading end 402.

[0034] Specifically, the upper die base 1 is provided with a stamping rod 11 that engages with the stamping plate 7. One end of the stamping rod 11 is externally connected to a stamping cylinder, which drives the stamping plate 7 to slide on the guide post 3 toward the forming plate 52, so that the stamping block 73 stamps the product on the conveyor turntable 4. Workers or external feeding equipment assemble the product on the conveyor turntable 4 from the feeding end 401. The feeding end 401 is located on the outside of the forming plate 52 (e.g., Figure 2 As shown in the figure, after the stamping is completed, the unloading cylinder 46 takes out the formed product away from the material conveying turntable 4, thereby improving the working efficiency of stamping the product.

[0035] As a further embodiment of this utility model, a fixed seat 711 is provided on the stamping plate 7, a pressure rod 713 is slidably provided on the fixed seat 711, a third spring 712 is provided between the pressure rod 713 and the fixed seat 711, a guide seat 41 is engaged on the material conveying turntable 4, a telescopic rod 45 that cooperates with the transmission unit 44 is slidably provided in the guide seat 41, a second spring is provided between the telescopic rod 45 and the guide seat 41, the pressure rod 713 and the telescopic rod 45 are on the same axis, during the process of the stamping plate 7 pressing down, the pressure rod 713 pushes the telescopic rod 45 to slide on the guide seat 41, so as to drive the transmission unit 44 to control the material conveying turntable 4 to rotate a certain angle to complete the stamping process of the product.

[0036] As a further embodiment of this utility model, a limiting groove 411 is provided on the guide seat 41, and the pressure rod 713 slides within the limiting groove 411. The elastic force of the third spring 712 is greater than that of the second spring. The limiting groove 411 limits the sliding distance of the pressure rod 713. During the downward pressing process of the pressure rod 713, since the elastic force of the third spring 712 is greater than that of the second spring, the pressure rod 713 can push the telescopic rod 45 downward while remaining stationary. When the pressure rod 713 contacts the limiting groove 411, that is, when the rotation of the material conveying turntable 4 ends, the stamping plate 7 gradually slides downward to perform stamping. The pressure rod 713 will squeeze the third spring 712 to retract into the fixed seat 711 to control the material conveying turntable 4 to stop the stamping movement after rotation. The sliding distance of the pressure rod 713 is the stamping time. When the stamping plate 7 finishes stamping and slides upward, the compressed second spring and third spring 712 respectively push the telescopic rod 45 and the pressure rod 713 back to the initial state.

[0037] As a further embodiment of this utility model, the transmission unit 44 includes a first bevel gear 442, a support base 441, and a rotating rod 445 rotatably connected to the support base 441. The first bevel gear 442 is engaged with a section of the material conveying turntable 4, and a second bevel gear 444 meshing with the first bevel gear 442 is provided on the rotating rod 445. The support base 441 is fixed on the forming plate 52. A swing rod 443 is rotatably provided at one end of the telescopic rod 45. The swing rod 443 cooperates with the rotating rod 445. When the telescopic rod 45 slides downward, the swing rod 443 at the rotating end 451 drives the rotating rod 445 to rotate, thereby causing the second bevel gear 444 to rotate. The rotation of the material conveying turntable 4 is controlled by the first bevel gear 442, so that the turntable rotates by a certain angle with the movement of the stamping plate 7 after each stamping of the mold.

[0038] As a further embodiment provided by this utility model, the number of teeth of the first bevel gear 442 is greater than the number of teeth of the second bevel gear 444. When the second bevel gear 444 rotates once, the first bevel gear 442 is linked to the material conveying turntable 4 to rotate at a certain angle, so that the clamping groove 42 under the stamping block 73 is replaced. The rotation angle is determined according to the number of clamping grooves 42.

[0039] As a further embodiment of this utility model, the conveying turntable 4 is provided with clamping grooves 42 arranged in a circular array. A workpiece positioning block 43 is provided in the clamping groove 42. The workpiece positioning block 43 is provided with a groove 431 that cooperates with the unloading cylinder 46. The clamping groove 42 corresponds to the first bevel gear 442. Every time the second bevel gear 444 rotates once, the conveying turntable 4 rotates by a certain angle, so that the clamping groove 42 located under the stamping block 73 is replaced.

[0040] As a further embodiment of this utility model, the output end of the unloading cylinder 46 is provided with a slider 461, and the slider 461 is provided with an unloading ring 462 that cooperates with the groove 431. The unloading ring 462 is a rubber sleeve with a rear arc-shaped part that fits against the product to improve the support effect on the product. Before stamping, the unloading ring 462 pushes the product to slide in the groove 431 until the product is fixed for stamping, which improves the product positioning effect. After stamping, the output of the unloading cylinder 46 pushes the product away from the workpiece positioning block 43 for unloading, thereby improving the unloading efficiency.

[0041] As a further embodiment of this utility model, a triangular fixing seat 72 is provided on the stamping plate 7, and the stamping block 73 is engaged with the triangular fixing seat 72. One of the two inclined angles of the triangular fixing seat 72 is located at the axis of the stamping plate 7, while the other inclined angle is engaged with the stamping block 73 to improve the stamping effect on the stamping block 73.

[0042] As a further embodiment of this utility model, the lower mold base 5 also includes a shim block 51, which is connected to the molding plate 52. The shim block 51 increases the distance between the molding plate 52 and the lower mold base 5, making it easier to install and remove the components in the transmission unit 44.

[0043] Working principle: During the stamping process, the product is placed from the loading end 401 into the groove 431 of the workpiece positioning block 43. At this time, the stamping plate 7 slides on the guide post 3 toward the forming plate 52 and squeezes the first spring 2 to compress it. During stamping, the pressure rod 713 will contact the telescopic rod 45 in advance, so that the telescopic rod 45 slides downward on the guide seat 41 to drive the rotating rod 445 to rotate. The second bevel gear 444 links the first bevel gear 442 to rotate, so that the feeding turntable 4 rotates to a certain angle and then stops. The unloading cylinder 46 retracts to make the unloading collar on the slider 461 engage with the product, so that the product position is more accurate. Then the product is squeezed and formed by the stamping block 73. The cylinder outputs to make the product move away from the workpiece positioning block 43 for unloading, thereby improving the stamping efficiency and reducing the phenomenon of damage to the hands or machine equipment during the loading or unloading process.
