[0034] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. To further understand the features, technical means, and specific objectives and functions achieved by the present invention, and to analyze the advantages and spirit of the present invention, a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments is provided below.

[0035] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intermediate component. When a component is considered to be "connected" to another component, it can be directly connected to the other component or there may be an intermediate component. The terms "vertical," "horizontal," "front," "back," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementation.

[0036] The continuous in-mold automatic stud mold of this application is used to automatically rivet studs 51 onto product strips 37. The product strips 37 include terminals 53, and the terminals 53 are provided with rivet positions 52 that cooperate with the studs 51.

[0037] The continuous die automatic stud mold of this application includes an upper die, a lower die and an automatic stud mechanism 21. The upper die is located above the lower die. The lower die includes a lower die base 19, a lower pad plate 18 and a lower template plate 17 stacked upwards in sequence. The upper die includes a stripper plate 16, a back stripper plate 15, an upper clamping plate 14, an upper pad plate 13, an upper die base 12 and an upper cover plate 11 stacked upwards in sequence.

[0038] The automatic riveting stud mechanism 21 includes a riveting punch 31, a feeding assembly 61, a transmission component 58, a force transmission pin 32, and an anti-backward assembly 63; the feeding assembly 61 includes a stacked power gear 33 and a feeding plate 38; the transmission assembly 62 includes a transmission component 58 and a force transmission pin 32; the anti-backward assembly 63 includes a fixed base 34 and an anti-backward hook 47.

[0039] The riveting punch 31 is disposed in the upper clamping plate 14;

[0040] The force transmission pin 32 is disposed in the stripper plate 16;

[0041] The lower template 17 has a frame opening 23;

[0042] The feeding assembly 61 is rotatably disposed in the frame opening 23. The feeding assembly 61 includes a stacked power gear 33 and a feeding tray 38.

[0043] The transmission component 58 is slidably disposed in the frame opening 23. The transmission component 58 is meshed with the teeth of the power gear 33. The force transmission pin 32 drives the transmission component 58 to move laterally so as to drive the power gear 33 to rotate, so that the feeding plate 38 rotates to feed the material.

[0044] The anti-backward component 63 is installed in the frame opening 23 and abuts against the power gear 33. During the resetting process of the transmission component 58, the anti-backward component 63 prevents the power gear 33 from rotating in the opposite direction.

[0045] Specifically, the stamping device drives the upper and lower dies to close. The upper die drives the riveting punch 31 and the force transmission pin 32 to move downward. The force transmission pin 32 first cooperates with the transmission component 58 to drive the transmission component 58 to move laterally, thereby driving the feeding tray 38 to rotate to realize feeding. This makes the riveting position 52 of the product strip 37 correspond to the stud 51. Then the riveting punch 31 rivets the stud 51 onto the riveting position 52. When the mold opens, during the reset process of the transmission component 58, the anti-backward component 63 remains in contact with the power gear 33 to prevent the power gear 33 from rotating in the opposite direction. The above actions are repeated to realize the automatic riveting of the stud 51 onto the riveting position 52 of the product strip 37, reducing manufacturing costs and improving production efficiency.

[0046] In another embodiment of the present invention, the power gear 33 is an inverted gear; specifically, the inverted gear, in conjunction with the transmission component 58 and the anti-backward component 63, further improves the unidirectional rotation effect of the feeding disc. The inverted gear is an existing structure, and in this embodiment it is applied in conjunction with the transmission component 58 and the anti-backward component 63 to improve the unidirectional rotation effect. Its specific structure will not be described in detail here.

[0047] In another embodiment of the present invention, the feeding assembly 61 further includes a fixed shaft 41 and fixed wheels 45; the feeding disc 38, the power gear 33, and the fixed wheels 45 are all coaxially arranged on the fixed shaft 41, and fixed wheels 45 are provided on both sides of the power gear 33; the diameter of the fixed wheels 45 is larger than the diameter of the power gear 33, and the fixed wheels 45 slide against the frame opening 23; specifically, the two fixed wheels 45 at the upper and lower ends of the power gear 33 make the structure more stable, and the diameter of the two fixed wheels 45 is larger than the diameter of the power gear 33; the fixed wheels 45 slide against the side wall of the frame opening 23, which can avoid the power gear 33 from colliding with the side wall of the frame opening 23 and improve the stability of rotation.

[0048] In another embodiment of the invention, the transmission member 58 includes a movable seat 48 and a transmission hook 42;

[0049] The movable base 48 has a card slot 28, which cooperates with the force transmission pin 32. The side of the force transmission pin 32 away from the card slot 28 has a pushing slope 26 that is inclined towards the card slot 28. The side wall of the card slot 28 near the force transmission pin 32 has a transmission slope 27 that matches the pushing slope 26. The movable base 48 has a spring fixing hole 49 facing the transmission hook 42. The spring fixing hole 49 is perpendicular to the force transmission pin 32, and a spring is installed in the spring fixing hole 49.

[0050] The movable base 48 is provided with mounting holes, and the transmission hook 42 is installed in the mounting holes. One end of the transmission hook 42 is engaged with the power gear 33. An elastic element is provided between the end of the transmission hook 42 facing away from the power gear 33 and the frame opening 23. Specifically, when the mold moves up and down, it will push the movable base 48 to move back and forth through the force transmission pin 32 (transmission rod). When the mold moves down, the force transmission pin 32 will push the movable base 48 to move laterally. When the transmission hook 42 hooks the power gear 33 to rotate, the transmission hook 42 drives the power gear 33 to rotate clockwise, and at the same time, it drives the feeding plate 38 to rotate synchronously. When the transmission hook 42 is moved by the movable base 48, the feeding plate 38 (receiving position 39 groove) rotates with the stud 51 to the corresponding riveting position 52 (riveting hole) on the terminal 53. The riveting punch 31 rivets the stud 51 and the terminal 53 together. When the mold opens, the force transmission pin 32 leaves the movable seat 48, and the spring pushes the movable seat 48 to return to its original position. The transmission hook 42 is brought to the origin position by the movable seat 48, ready for the next reciprocating motion.

[0051] The transmission hook 42 is equipped with a spring. When the transmission hook 42 moves laterally (translates) relative to the power gear 33, the transmission hook 42 hooks the reverse gear of the power gear 33 to ensure that the power gear 33 can rotate. When the transmission hook 42 returns to its original position, the transmission hook 42 and the power gear 33 are in a guide angle fit, and the transmission hook 42 can be smoothly disengaged.

[0052] In another embodiment of the present invention, the push-up inclined surface 26 adopts a second-order guide structure. Specifically, the second-order guide structure improves the stability of the engagement between the force transmission pin 32 and the movable seat 48.

[0053] The anti-backward assembly 63 includes a fixed base 34, in which an anti-backward hook 47 facing the power gear 33 is installed. The anti-backward hook 47 is symmetrically matched with the transmission hook 42. The hook of the anti-backward hook 47 is opposite to the hook of the transmission hook 42, and the hook of the anti-backward hook 47 is tangent to the power gear 33.

[0054] Furthermore, in one embodiment, the anti-reverse hook 47 engages with the drive gear 33 to prevent the gear from reversing. A spring is installed inside the anti-reverse hook 47. When the drive gear 33 rotates clockwise, the anti-reverse hook 47 and the drive gear 33 are in a guide angle engagement, which allows for smooth retraction.

[0055] In another embodiment of the present invention, a positioning wheel 44 and a positioning hook 46 are also included. The positioning wheel 44 is installed in the feeding assembly 61 and located below the power gear 33. The positioning hook 46 is installed in the anti-backward assembly 63 and cooperates with the positioning wheel 44. Further, the positioning hook 46 is disposed on the fixed base 34. The positioning hook 46 is disposed below the anti-backward hook 47, and the positioning hook 46 and the anti-backward hook 47 are arranged side by side, with the hook tip of the positioning hook 46 engaged in the groove of the positioning wheel 44. A spring is provided at the end (outer end) of the positioning hook 46 away from the fixed shaft 41. Specifically, the positioning wheel 44 and the positioning hook 46 cooperate with each other to improve the rotation position of the feeding disc 38, thereby improving the accuracy of the assembly position.

[0056] In another embodiment of the invention, the number of teeth in the slot of the positioning wheel 44 is equal to that of the power gear 33.

[0057] Furthermore, the feed tray 38 is provided with multiple receiving positions 39 around its periphery. Each step of the reverse gear on the power gear 33 corresponds to a receiving position 39 on the feed tray 38. In other words, the N reverse gears on the power gear 33 correspond one-to-one with the N receiving positions 39 on the feed tray 38. The reverse gears on the power gear 33 are matched with the slots on the positioning wheel 44. In other words, the N reverse gears on the power gear 33 correspond one-to-one with the N slots on the positioning wheel 44.

[0058] In another embodiment of the present invention, a retaining ring 55 is further provided between the positioning wheel 44 and the drive gear 33. Specifically, the retaining ring 55 provides a distance between the positioning wheel 44 and the drive gear 33, and retaining rings 55 of different thicknesses can be replaced according to different products to adjust the height of the feeding tray 38.

[0059] In another embodiment of the invention, the diameter of the positioning wheel 44 is smaller than the diameter of the drive gear 33.

[0060] In another embodiment of the present invention, the continuous die automatic stud riveting mold further includes a guide plate 35, which is installed on the lower template 17 and located on the side of the loading tray 38. The guide plate 35 has a guide groove 54 in the middle that extends toward the loading tray 38. The end of the guide groove 54 away from the loading tray 38 has a feed port 36 for receiving studs 51. A plurality of receiving positions 39 corresponding to the guide groove 54 are opened on the outer side wall of the top of the loading tray 38. The plurality of receiving positions 39 are evenly distributed on the outer side wall of the top periphery of the loading tray 38. The receiving positions 39 are matched and corresponding to the guide groove 54. The receiving positions 39 are used to load the studs 51 transmitted from the guide groove 54.

[0061] In another embodiment of the present invention, a bottom top seat 29 is provided in the lower template 17. The bottom top seat 29 is installed below the feeding tray 38 and matches and corresponds to the riveting punch 31. More specifically, the bottom top seat 29 is located directly below the receiving position 39, that is, the bottom top seat 29, the receiving position 39, and the riveting punch 31 are on the same vertical line. Specifically, the bottom top seat 29 and the riveting punch 31 cooperate to rivet the stud 51 onto the terminal 53. After the bottom top seat 29 is worn due to frequent contact with the product strip 37, the bottom top seat 29 can be disassembled separately without replacing the entire lower template 17.
