[0052] From the structural description of the above automatic die punching device, it can be known that the processing method of the automatic die punching device of the utility model is:

[0053] S1: placing the workpiece to be processed on the first carrier 11 and the second carrier 12 manually or by a robot. Specifically, the product G is placed on the first carrier 11, and a part of the plastic part S is placed on the second carrier 12. It can be understood that the remaining part of the plastic part S is suspended in the air, so as to facilitate the subsequent punching operation of the punching blade 31.

[0054] S2: the upper die base 20 is controlled to move downward, and accordingly, the ram 30 and the punching member 31 move downward together with the upper die base 20, and then the ram 30 elastically presses the product G placed on the first carrier 11, and then the punching member 31 punches and cuts the plastic part S, so that the plastic part S is separated from the product G;

[0055] In addition, during the downward movement of the upper die base 20, the upper die base 20 can also drive the first punch needle 40 to perform downward punching movement relative to the first carrier 11, and at the same time drive the second punch needle 41 to perform lateral punching movement relative to the first carrier 11, thereby realizing the punching processing of the product part G placed on the first carrier 11 by the first punch needle 40 and the second punch needle 41 respectively.

[0056] Note: Regarding the above-mentioned "punching process", it can be understood as using the first punch needle 40 and the second punch needle 41 to respectively process the required holes on the product G; it can also be understood as using the first punch needle 40 and the second punch needle 41 to respectively punch out the plastic material (plastic material comes from the injection molding process and is waste) filled in the preset hole of the product G to obtain the processed hole. In short, the specific content of the "punching process" is determined according to the product processing requirements, and this patent does not describe them one by one.

[0057] As can be seen from the above, compared with the prior art, the punching die device of the utility model can realize punching / punching processing of the main surface, side surface and other positions of the workpiece at one time, and the processing efficiency is very high. In particular, the punching die device of the utility model is only equipped with a set of power parts to drive the punching mechanism and the punching mechanism to act synchronously, which greatly simplifies the device structure, reduces the size of the device, simplifies the installation layout and control implementation of the device, and reduces the processing cost of the device, which is very beneficial to the production implementation of the device.

[0058] The specific structure of the automatic die punching device of the utility model is described in detail below.

[0059] First, let us discuss the punching mechanism 3 .

[0060] Please refer to the attached Figure 1 , Attachment Figure 2 , Attachment Figure 7 To Attachment Fig.11 As shown, in this embodiment 1, the structure that realizes the connection of the ram 30 to the lower side of the upper die seat 20 with elastic movement up and down is as follows: the punching mechanism 3 is further provided with a connecting member 32 that can slide up and down and is arranged on the lower side of the upper die seat 20, and an elastic member 33 that is elastically connected between the upper side of the connecting member 32 and the upper die seat 20; the ram 30 is fixedly connected to the lower side of the connecting member 32, and is located directly above the first carrier 11. That is, the ram 30 is connected to the lower side of the upper die seat 20 with elastic movement up and down through the combination of the connecting member 32 and the elastic member 33.

[0061] Based on the installation method of the above-mentioned ram 30, the punching blade 31 preferably adopts the following structure and installation method: the punching blade 31 is provided with a knife seat 310 which is sleeved outside the lower part of the connecting member 32 and fixedly connected to the lower side of the upper die seat 20, a through hole 311 provided on the knife seat 310 and through which the ram 30 can freely pass, and a cutting blade portion A312 provided on the knife seat 310 and corresponding to the position to be punched of the plastic part S. It can be understood that the punching blade 31 is fixed relative to the upper die seat 20 as a whole, and the ram 30 can move elastically up and down on the punching blade 31. In addition, the position to be punched of the plastic part S is the connection between it and the product part G.

[0062] Based on the above-mentioned structure and installation method of the ram 30 and the punching blade 31, the working method of the punching mechanism 3 can be further understood as follows: when the upper mold base 20 moves downward to the first position, the ram 30 can elastically press against the product part G on the first carrier 11; when the upper mold base 20 continues to move downward to the second position, the cutter part A312 can punch the position to be punched of the plastic part S, and in the process of the upper mold base 20 moving downward from the first position to the second position, the ram 30 always maintains elastic pressure on the product part G on the first carrier 11.

[0063] Further preferably, the specific structure of the connecting member 32 used in this embodiment 1 is as follows: Figure 7 To Attachment Fig.11 As shown, the connecting member 32 includes a guide column 320 extending vertically and movably inserted into the lower side of the upper mold base 20, and an upper plate 321 and a lower plate 322 fixedly connected to the upper and lower ends of the guide column 320, respectively. The upper plate 321 and the lower plate 322 are both arranged horizontally and parallel to each other, and the upper side of the upper plate 321 is elastically connected to the upper mold base 20 through the elastic member 33.

[0064] Based on the structure of the connecting member 32, the pressing head 30 is fixedly connected to the lower plate 322. Specifically, the upper portion of the pressing head 30 is fixedly embedded in the lower plate 322 and exposed outside the upper surface of the lower plate 322, so as to facilitate the installation and arrangement of the first punching needle 40 described below. In addition, the shape of the lower side of the pressing head 30 matches the shape of the product G, so as to achieve balanced pressure on the product G.

[0065] Further preferably, in the punching blade 31 structure used in the present embodiment 1, the specific structure of each part and the connection relationship between each part are as follows: Figure 7 To Attachment Fig.12As shown, the knife seat 310 is a U-shaped groove structure, and is freely sleeved outside the lower plate 322 and the lower part of the guide column 320; and the top side of the knife seat 310 (i.e., the slot side of the knife seat 310) is fixedly connected to the lower side of the upper die seat 20. In addition, it can be understood that the gap height between the inner surface of the groove bottom of the knife seat 310 and the top side of the knife seat 310 should not be less than the upward or downward displacement of the lower plate 322 to meet the movement requirements of the lower plate 322.

[0066] The through hole 311 is integrally arranged at the bottom of the groove of the tool holder 310, and passes through the upper and lower surfaces of the bottom of the groove of the tool holder 310 respectively, that is, the through hole 311 is a vertical through hole; and the transverse cross-sectional shape of the through hole 311 also matches the transverse cross-sectional shape of the pressure head 30 to improve the accuracy of the pressure head 30 when moving up and down.

[0067] The cutter part A312 is integrally arranged on the lower surface of the groove bottom of the cutter seat 310 and is connected to the lower edge of the through hole 311. As mentioned above, the cutter part A312 is used to punch the end of the plastic part S connected to the product part G.

[0068] More preferably, in this embodiment 1, according to the shape of the workpiece to be processed (specifically, the shape of the plastic part S), the perforation 311 is also used in a special way, that is, a part of the lower edge of the perforation 311 is used as a cutter part B313, that is, the cutter part B313 cooperates with the cutter part A312 to punch out the plastic part S from the product part G. For details, please refer to the attached Fig.12 shown.

[0069] According to the layout of the first carrier 11 and the second carrier 12, an escape groove 314 for evading the second carrier 12 is also provided on the lower surface of the groove bottom of the knife seat 310. Fig.12 shown.

[0070] Next, let us discuss the lower mold unit 1 and the upper mold unit 2 .

[0071] Please continue to refer to the attached Figure 1 To Attachment Figure 4As shown, in this embodiment 1, the structure for realizing that the upper die seat 20 is located above the lower die seat 10 and can move up and down relative to the lower die seat 10 is as follows: the lower die unit 1 is also provided with a guide support column 13 and a lower limit column 14 respectively vertically and fixedly arranged on the upper side of the lower die seat 10; the upper die seat 20 is a vertically placed frame structure, the upper die seat 20 is slidably arranged on the guide support column 13 through a shaft sleeve, and the lower side of the upper die seat 20 is provided with an upper limit column 21 arranged up and down relative to the lower limit column 14, wherein the upper limit column 21 can cooperate with the lower limit column 14 to limit the downward movement of the upper die seat 20. And, the upper die unit 2 is also provided with a power piece that can drive the upper die seat 20 to move up and down.

[0072] As for the power part, it can adopt a linear drive mechanism such as a hydraulic cylinder, a pneumatic cylinder, or a combination of a motor and a lead screw module, which is a commonly used technical means in the field of mechanical automation, so it will not be described in detail here.

[0073] In addition, in combination with the structure of the connecting member 32, the upper plate 321 is movably built into the upper die seat 20, and the lower plate 322 is movably disposed outside the upper die seat 20. It is also understandable that the lower side of the upper die seat 20 is further provided with a guide hole 22 for the guide column 320 to freely pass through.

[0074] According to the structure of the connecting member 32, the upper side of the upper plate 321 is elastically connected to the upper die holder 20 through the elastic member 33. Specifically, the following structure can be adopted: Please continue to refer to the attached Figure 3 , Attachment Figure 4 and attached Figure 7 As shown, the punching mechanism 3 is also provided with a connecting rod 34, the upper end of the connecting rod 34 is fixedly connected to the upper side of the upper die base 20, and the lower side of the connecting rod 34 is movably inserted into the upper plate 321 and the lower side of the upper die base 20 in turn, and the elastic member 33 adopts a spring and is sleeved outside the connecting rod 34, and the upper and lower ends of the elastic member 33 are respectively fixedly connected to / or elastically abutted with the upper side of the upper die base 20 and the upper plate 321.

[0075] In addition, in this embodiment 1, please continue to refer to the attached Figure 6 As shown, a groove A110 matching the shape of the product G is provided on the upper side of the first carrier 11 for placing the product G; a groove B120 matching the partial shape of the plastic part S is provided on the upper side of the second carrier 12 for placing the partial part of the plastic part S.

[0076] In addition, the second carrier 12 is configured as one and is centrally disposed on the upper side of the lower mold base 10 ; the first carrier 11 is configured as two and is symmetrically disposed on opposite sides of the second carrier 12 .

[0077] Based on the configuration of the first carrier 11 and the second carrier 12, the configuration quantities of the ram 30, the first punch 40 and the second punch 41 correspond to the quantity of the first carrier 11. Specifically, the ram 30 and the second punch 41 are configured in two, respectively, to correspond one-to-one with the first carrier 11; the first punch 40 is configured in two pairs, to correspond one-to-one with the first carrier 11. And it can be understood that the configuration quantities of the perforation 311, the cutter part A312, the cutter part B313, and the following guide block 42, passive block 44, active block 23, etc. are also adjusted accordingly according to the changes in the configuration quantities of the first carrier 11, the ram 30, the first punch 40 and the second punch 41. Therefore, it will not be described in detail here.

[0078] Next, let's discuss the punching mechanism 4 .

[0079] Please continue to refer to the attached Figure 7 To Attachment Fig.11 As shown, in this embodiment 1, the structure that realizes the first punch needle 40 being arranged on the ram 30 and being able to perform downward punching movement relative to the first carrier 11 under the drive of the upper die seat 20 is as follows: the first punch needle 40 is provided with a punch needle body 400 vertically and movably inserted in the ram 30 and a head 401 arranged at the upper end of the punch needle body 400 and capable of stopping outside the upper side of the ram 30; when the upper die seat 20 moves downward, the lower side of the upper die seat 20 can press against the head 401 and drive the first punch needle 40 to move downward as a whole, thereby making the lower end of the punch needle body 400 exposed outside the lower side of the ram 30 and punching into the product G placed on the first carrier 11. Note: Regarding "the lower side of the upper die seat 20 can press against the head 401", it can be understood that the lower side of the upper die seat 20 directly presses against the head 401, or the lower side of the upper die seat 20 presses against the head 401 indirectly.
