[0032] Please see Figures 1 to 6 As shown, this embodiment provides a stamping die for preventing material jamming, which includes an upper die 10, a lower die 20, and an anti-jamming component 30. The upper die 10 includes an upper die base 11, an upper die fixing plate 12, and a die cavity 13 arranged from top to bottom. The bottom of the upper die fixing plate 12 has a plurality of first mounting holes 120 spaced equidistantly in a ring shape along the center position, and a first spring 14 is provided in each first mounting hole 120. The die cavity 13 has a plurality of second mounting holes 130 corresponding to the first mounting holes 120, and one end of the first spring 14 is disposed in a second mounting hole 130. The lower die 20 includes a lower die base 21 and a punch 22. The lower die base 21 and the upper die cavity 20 are connected to the upper die cavity 10. The mold base 11 is connected by guide pillars, and the punch 22 is set on the lower mold base 21. The anti-jamming assembly 30 includes a mounting plate 31, an ejector plate 32, and a second spring 33. The mounting plate 31 is set on the lower mold base 21. A first mounting groove is opened in the middle position of the mounting plate 31. The ejector plate 32 is set in the first mounting groove. The ejector plate 32 has multiple third mounting holes spaced equidistantly in a ring shape along its center position. One end of the second spring 33 is set in the third mounting hole. A second mounting groove is opened in the middle position of the ejector plate 32. The punch 22 is set in the second mounting groove. The ejector plate 32 is configured to cooperate with the second spring 33 to lift the product on the punch 22.

[0033] Specifically, the bottom of the upper mold fixing plate 12 has eight first mounting holes 120 spaced equidistantly in a ring shape along the center position.

[0034] As can be seen, the first spring 14 of the upper die 10 provides a buffer for the die 13 to prevent the material from getting stuck due to rigid contact during stamping. The anti-jamming component 30 of the lower die 20 cooperates with the second spring 33 through the ejector plate 32 to lift the product from the punch 22 after stamping, preventing the product from getting stuck due to excessive tightness.

[0035] In one embodiment, the inner wall of the mounting plate 31 is vertically provided with multiple guide grooves 34, and each end of the guide groove 34 is provided with a limiting block. The outer wall of the ejector plate 32 is provided with multiple guide blocks 35 corresponding to the guide grooves 34, and the edges of the guide blocks 35 are rounded.

[0036] Specifically, the inner wall of the mounting plate 31 is vertically provided with four guide grooves 34, and the outer wall of the ejector plate 32 is provided with four guide blocks 35 corresponding to the guide grooves 34.

[0037] As can be seen, by cooperating with the guide groove 34 of the mounting plate 31 and the guide block 35 of the ejector plate 32, the movement direction of the ejector plate 32 is restricted, preventing tilting caused by uneven force during ejection, ensuring smooth ejection action, and avoiding the product being pushed off-center and stuck at the edge of the punch 22.

[0038] In one embodiment, the top of the upper mold fixing plate 12 is provided with a plurality of fourth mounting holes 121 at equal intervals in a ring along the center position. The fourth mounting holes 121 are configured to install the first punch 15. Two fifth mounting holes 122 are symmetrically provided inside the fourth mounting holes 121. The fifth mounting holes 122 are configured to install the second punch 16. A sixth mounting hole 123 is provided on one side of the fifth mounting holes 122. The sixth mounting hole 123 is configured to install the third punch 17.

[0039] As can be seen, different sizes of punches are installed in the fourth, fifth and sixth mounting holes, which can complete multiple processes such as punching and trimming in one stamping process, reduce the number of product transfers and improve production efficiency.

[0040] In one embodiment, the die 13 is provided with a plurality of first positioning holes corresponding to the first mounting hole 120, and the first positioning holes are configured to install one end of the first spring 14.

[0041] As can be seen, the first positioning hole of the die 13 precisely fixes the position of the first spring 14, preventing the first spring 14 from shifting or falling off during the stamping process, ensuring the stability of the buffering function of the first spring 14, and avoiding uneven force on the die 13 caused by the misalignment of the first spring 14.

[0042] In one embodiment, a first through hole is provided on the die 13 corresponding to the fourth mounting hole 121. The first through hole is located inside the fourth mounting hole 121 and between the two fourth mounting holes 121. The first through hole is configured to pass through the first punch 15.

[0043] As can be seen, the first through hole of the die 13 corresponds to the first punch 15, providing clearance for the first punch 15 and ensuring that the first punch 15 can pass smoothly through the die 13 to complete the forming during stamping.

[0044] In one embodiment, the punch 22 is provided with a first blanking hole 220, a second blanking hole 221 and a third blanking hole 222 respectively corresponding to the fourth mounting hole 121, the fifth mounting hole 122 and the sixth mounting hole 123.

[0045] As can be seen, through the cooperation of the blanking hole and the punch, the waste generated by stamping can be directly discharged through the blanking hole, avoiding the accumulation of waste in the mold cavity and causing jamming, thus keeping the stamping environment clean.

[0046] In one embodiment, a second positioning hole is provided on the lower mold base 21 corresponding to the third mounting hole, and the second positioning hole is configured to accommodate one end of the second spring 33.

[0047] As can be seen, fixing the second spring 33 through the second positioning hole prevents the spring from shifting during ejection, ensures that the ejector plate 32 is subjected to uniform force, and avoids weak ejection or product deviation caused by spring misalignment.

[0048] In one embodiment, the top of the ejector plate 32 is provided with a stamping part 320, which is arranged adjacent to the punch 22. The stamping part 320 is configured to cooperate with the die 13 to stamp the material and cooperate with the second spring 33 to lift the stamped product.

[0049] As can be seen, the material is formed by the stamping part 320 in conjunction with the die 13, and is lifted by the second spring 33 after stamping. The structure is simplified and easy to use.

[0050] In the embodiments disclosed in this utility model, the terms "installation," "connection," "linking," and "fixing" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; "linking" can be a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in the embodiments disclosed in this utility model according to the specific circumstances.

[0051] The above embodiments merely illustrate the basic principles and characteristics of this utility model. This utility model is not limited to the above examples. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
