[0013] Compared with the prior art, the in-mold bending and punching device provided by the present invention has the following advantages:

[0014] 1. An in-mold bending and punching device, comprising a first assembly and a second assembly. The first assembly is sequentially equipped with a first cutter and a first forming mold. The second assembly comprises a fixed frame, a wire feeder, a second cutter, and a second forming mold. The wire feeder is mounted on the fixed frame and functions to convey linear raw materials. The wire feeder is also equipped with a bending module. The bending module, when mounted on the wire feeder, enables the in-mold bending and punching device to simultaneously deliver the wire and bend the linear raw materials. The second forming mold is mounted on the fixed frame and cooperates with the first forming mold to perform injection molding of the bent raw materials. The first cutter and the second cutter cooperate to perform punching. By consolidating the wire feeding, bending, and punching functions within the mold, the structure is highly compact, effectively consolidating different processes into a single device. Furthermore, due to the compact structure between the different workstations, processing efficiency is significantly improved, allowing for convenient and rapid completion of the steps of wire feeding, bending, punching, and injection molding.

[0015] 2. The in-mold bending and punching device also includes a base and a buffer spring. The base is movably connected to the side of the mounting bracket away from the first component, and the buffer spring is located between the mounting bracket and the base. The buffer spring between the base and the mounting bracket effectively reduces impact during the mold closing process and effectively prevents damage to the first and second components from colliding.

[0016] 3. The in-mold bending and punching device also includes a wire pressing block assembly, which is arranged at the end of the fixed frame away from the bending mold. The wire pressing block assembly can further fix the wire on the wire feeding platform and prevent the wire from sliding back.

[0017] 4. The wire feeding device includes a first drive unit, a second drive unit, a wire feeding platform, and a wire clamp assembly. The wire feeding platform is movably mounted on a fixed frame and, in conjunction with the first drive unit, enables reciprocating motion on the fixed frame to deliver the wire.

[0018] 5. The wire clamp assembly includes a wire clamp body, a first screw, and a first spring. The fixing frame is provided with a first screw hole. The first screw passes through the first spring, the wire clamp body, and the first screw hole of the fixing frame in sequence. The first spring is in a compressed state. The first eccentric shaft is connected to the wire clamp body. Under the action of the first spring, the wire clamp body tends to move toward the fixing frame, enabling it to clamp the wire. When the first eccentric shaft rotates to move the wire clamp body away from the fixing frame, the first spring is further compressed, and the wire is released from the clamping state. This structural arrangement allows the first screw to be adjusted at any time to achieve the optimal compression level of the first spring, resulting in a simple structure and easy maintenance.

[0019] 6. The first driving device includes a first cylinder and a first movable rod. The first movable rod is telescopically arranged in the first cylinder.

The structure is simple and the control is convenient.

[0020] 7. The second drive device includes a motor, a transmission device, and an eccentric rod. The motor is fixed to a fixed frame, and the transmission device is fixed to the fixed frame. The motor and the eccentric rod are connected through the transmission device, so that the second drive device can drive the eccentric rod to rotate. The eccentric rod is equipped with a first eccentric shaft and a second eccentric shaft. The first and second eccentric shafts are eccentric in opposite directions and are respectively connected to the wire clamp assembly and the bending die. When the eccentric rod rotates, the wire clamp assembly and the bending die alternately open and close, resulting in a simple structure and easy control.

[0021] 8. The bending die includes a bending die body, a second screw and a second spring. The bending die body is provided with a second screw hole. The second screw passes through the second spring, the wire feeding platform and the second screw hole of the bending die body in sequence. The second spring is in a compressed state. The second eccentric shaft is connected to the bending die body. Under the action of the second spring, the bending die body tends to move toward the bending punch. When the second eccentric shaft rotates to make the bending die body move toward the bending punch, the bending punch and the bending punch are tightened to achieve bending of the wire. Otherwise, the tightening state of the bending die body and the bending punch is released, allowing the wire to pass through. It only needs to control the eccentric rod to achieve wire clamping and wire bending, and the control is simple and convenient.

[0022] 9. The transmission device is a two-stage gear transmission, and the efficiency of energy transmission is high.

[0023] 10. The first component is also provided with a mold sliding device, which can drive the first component to perform a sliding action, that is, when the first component is separated from the second component, the mold sliding device drives the first component to move perpendicular to the separation direction of the first component and the second component.

DETAILED DESCRIPTION

[0035] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and implementation examples. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly attached to the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only.

[0037] See also Figure 1 The present invention provides an in-mold bending and punching device 1000, which includes a first component 1100 and a second component 1200. The second component 1200 is fixedly arranged on an external fixed structure. The first component 1100 can be installed on an external driving device, and the external driving device drives the first component 1100 to complete the opening and closing of the first component 1100 and the second component 1200. The first component 1100 includes a main body 1101, and a first cutter 1110 and a first forming mold 1120 fixedly arranged on the main body 1101. The first cutter 1110 and the first forming mold 1120 are fixedly connected to the main body 1101. The second component 1200 includes a fixed frame 1210, a wire feeding device 1220, a second cutter 1230 and a second forming mold 1240. The wire feeding device 1220 is arranged on the fixed frame 1210, and the wire feeding device 1220 serves to transport linear processing raw materials. Optionally, the linear processing raw materials include metal wires waiting for processing raw materials. The wire feeding device 1220 is also provided with a bending module 1250. The bending module 1250 is arranged on the wire feeding device 1220, so that the in-mold bending and punching device 1000 can realize the bending of the linear processing raw materials while realizing wire feeding. The second molding die 1240 is fixed on the fixed frame 1210, and is located on the side of the bending die 1251 away from the wire feeding device 1220, and cooperates with the first molding die 1120. After the bending module 1250 completes the bending of the linear processing raw materials, the processing raw materials are injection molded to obtain the accessories required for the product. The first cutter 1110 and the second cutter 1230 cooperate to realize the punching function.

[0038] Optionally, in some other embodiments, the raw material to be processed is not limited to linear raw materials, but may also be sheet-shaped or other forms of raw materials to be processed.

[0039] When it is necessary to produce a molded product, the bending module 1250 first completes the bending of the linear processing material, and then the wire feeding device 1220 feeds the linear processing material out, and then the first component 1100 and the second component 1200 are combined. At this time, the first cutter 1110 and the second cutter 1230 are combined to cut the linear processing material after bending, and the first molding die 1120 and the second molding die 1240 form a space of a specific shape, and the space is subjected to grouting molding to obtain the required product. Through this structure that concentrates the wire feeding, bending and punching functions in the mold, the structure has a high degree of compactness, and different processes can be well concentrated on one device. At the same time, due to the compact structure between different workstations, the processing efficiency can be greatly improved, and the steps of wire feeding, bending, punching and injection molding can be conveniently and quickly realized.

[0040] Please refer to Figure 1 A mold sliding device 1300 is also provided on the main body 1101 of the first component 1100. The mold sliding device 1300 passes through the main body 1101. When the mold sliding device 1300 is fixed by an external driving device, the first component 1100, the mold sliding device 1300 can drive the first component 1100 to perform a sliding action, that is, when the first component 1100 is separated from the second component 1200, the first component 1100 is driven to move perpendicular to the separation direction of the first component 1100 and the second component 1200. By performing separation movements in different directions at the same time, the product can be easily removed from the mold.

[0041] The mold sliding device 1300 includes a sliding motor 1301 and a screw rod 1302. The sliding screw rod 1302 is the rotating shaft of the motor 1301. The screw rod 1302 passes through the main body 1101 in a direction parallel to the wire feeding direction. When the mold sliding device 1300 is fixed, the screw rod 1302 rotates, and the main body 1101 will move along the direction of the screw rod 1302, thereby realizing mold sliding.

[0042] The in-mold bending and breaking device 1000 also includes a base 1600 and a buffer spring 1400. The buffer spring 1400 is arranged between the fixed frame 1210 and the base 1600, so that the fixed frame 1210 and the base 1600 are elastically connected. By arranging the buffer spring 1400 between the base 1600 and the fixed frame 1210, the impact during the mold closing process can be effectively reduced, and the first component 1100 and the second component 1200 can be prevented from colliding and causing damage.

[0043] See also Figure 2 and Figure 2AThe wire feeding device 1220 includes a first drive device 1221, a second drive device 1222, a wire feeding platform 1223, and a wire clamp assembly 1224. The wire feeding platform 1223 is located on the concave platform of the fixed frame 1210 and can slide along the fixed frame 1210. It is connected to the first drive device 1221, so that the wire feeding platform 1223 can reciprocate on the fixed frame 1210 under the drive of the first drive device 1221 and the second drive device 1222, thereby realizing the wire feeding function. The wire clamp assembly 1224 can be located on the fixed frame 1210, which completely surrounds the wire feeding platform 1223 and can clamp the wire on the wire feeding platform 1223 to prevent the wire from sliding backward.

[0044] In some embodiments, the wire feeding platform 1223 is provided with a wire groove 12231, and the opening direction of the wire groove 12231 is consistent with the movement direction of the wire feeding platform 1223. Optionally, in some specific embodiments, the width of the wire groove 12231 is slightly smaller than the width of the wire, which helps to increase the friction between the wire feeding platform 1223 and the wire when feeding the wire, thereby facilitating the clamping of the wire and preventing the wire from slipping.

[0045] Please refer again Figure 2A The bending module 1250 includes a bending die 1251 and a bending punch 1252. The bending punch 1252 is fixed on the wire feeding platform 1223. The bending die 1251 is arranged on the wire feeding platform 1223 and can move along a sliding direction perpendicular to the wire feeding platform 1223 and cooperate with the bending punch 1252. The engagement of the bending die 1251 and the bending punch 1252 can conveniently realize the bending of the wire passing through the bending module 1250.

[0046] See also Figure 3 The first driving device 1221 includes a first cylinder 1225 and a first movable rod 1226. The first movable rod 1226 is telescopically arranged in the first cylinder 1225. The wire feeding platform 1223 is connected to the end of the first movable rod 1226 away from the first cylinder 1225, so that the first driving device 1221 can drive the wire feeding platform 1223 to perform reciprocating motion on the fixed frame 1210 to complete the wire feeding action. The structure is simple and the control is convenient.

[0047] See also Figure 4 and Figure 4AThe second driving device 1222 includes a motor 1227, a transmission device 1228, and an eccentric rod 1229. The motor 1227 is fixed to the fixing frame 1210, and the transmission device 1228 is fixed to the fixing frame 1210. The motor 1227 is connected to the eccentric rod 1229 through the transmission device 1228, so that the second driving device 1222 can drive the eccentric rod 1229 to rotate. The eccentric rod 1229 is provided with a first eccentric shaft 12291 and a second eccentric shaft 12292. The first eccentric shaft 12291 and the second eccentric shaft 12292 have opposite eccentric directions and are respectively connected to the clamp assembly 1224 and the bending mold 1251. When the eccentric rod 1229 rotates, the clamp assembly 1224 and the bending mold 1251 are alternately opened and closed. That is, when the wire clamp assembly 1224 is closed, the bending mold 1251 is opened, and when the wire clamp assembly 1224 is opened, the bending mold 1251 is closed, which has a simple structure and is easy to control.

[0048] In some embodiments, the motor 1227 includes a servo motor, a stepper motor, or other power mechanisms.

[0049] In some embodiments, the transmission device 1228 is a two-stage gear transmission, which has a higher efficiency in energy transmission.

[0050] When the in-mold bending and breaking device 1000 is working, first, the wire clamp assembly 1224 is in an open state, and the bending mold 1251 is in a closed state, the first driving device 1221 drives the wire feeding platform 1223 to feed the unbent wire to the space surrounded by the bending mold 1251 and the bending punch 1252, and then the second driving device 1222 drives the eccentric rod 1229 to rotate 180 degrees. Since the eccentric directions of the first eccentric shaft 12291 and the second eccentric shaft 12292 are opposite, the bending mold 1251 is in an open state. It becomes closed to complete the bending of the newly entered wire, and at this time the bending mold 1251 also changes from closed to open, so the wire feeding platform 1223 can continue to feed the wire to send out the bent wire, and then the first component 1100 and the second component 1200 are combined together, so that the first molding mold 1120 and the second molding mold 1240 are closed to enclose the bent wire, and at the same time the first cutter 1110 and the second cutter 1230 are combined to cut the bent wire, and finally the product can be manufactured by injection molding.

[0051] See also Figure 5 and Figure 5AThe wire clamp assembly 1224 includes a wire clamp body 12241, a first screw 12242 and a first spring 12243. The fixing frame 1210 is provided with a first screw hole 12101. The first screw 12242 passes through the first spring 12243, the wire clamp body 12241 and the first screw hole 12101 of the fixing frame 1210 in sequence. The first spring 12243 abuts against the surface of the wire clamp body 12241. The first spring 12243 is in a compressed state. The first eccentric shaft 12291 is connected to the wire clamp body 12241. Under the action of the first spring 12243, the wire clamp body 12241 tends to move toward the fixing frame 1210, so that it can clamp the wire. When the first eccentric shaft 12291 rotates, causing the wire clamp body 12241 to move away from the fixing frame 1210, the first spring 12243 is further compressed, and the wire is released from the clamped state. With this structural arrangement, the first screw 12242 can be adjusted at any time to optimize the compression degree of the first spring 12243 , which has a simple structure and is easy to maintain.

[0052] In some embodiments, the number of the first screw 12242 , the first spring 12243 , and the first screw hole 12101 can be one or more.

[0053] In some preferred solutions, the number of the first screw 12242, the first spring 12243 and the first screw hole 12101 is four. Of course, the first screw 12242 can be other fastening parts. Please continue to refer to Figure 5 and Figure 5A The bending mold 1251 includes a bending mold body 12511, a second screw 12512 and a second spring 12513. The bending mold body 12511 is provided with a second screw hole. The second screw 12512 passes through the second spring 12513, the wire feeding platform 1223 and the second screw hole of the bending mold body 12511 in sequence, so that the second spring 12513 is in a compressed state. The second eccentric shaft 12292 is connected to the bending mold body 12511. The bending mold body 12511 is provided with a second screw hole. Under the action of 513, there is a tendency to move toward the bending punch 1252. When the second eccentric shaft 12292 rotates to make the bending die body 12511 move toward the bending punch 1252, the bending die 1251 and the bending punch 1252 are tightened to achieve bending of the wire. Otherwise, the tightening state of the bending die body 12511 and the bending punch 1252 is released, allowing the wire to pass through. It is only necessary to control the eccentric rod 1229 to achieve the clamping and bending of the wire, and the control is simple and convenient.

[0054] In some embodiments, the number of the second screw 12512, the second spring 12513 and the second screw hole can be one or more. Of course, the second screw 12512 can be other fastening parts.

[0055] In some preferred solutions, the number of the second screw 12512, the second spring 12513 and the second screw hole is four.

[0056] See also Figure 6 The in-mold bending and punching device 1000 also includes a wire pressing block assembly 1500, which is arranged at one end of the fixing frame 1210 away from the bending mold 1251. The wire pressing block assembly 1500 can further fix the wire on the wire feeding platform 1223 and prevent the wire from sliding back.

[0057] The wire pressing block assembly 1500 includes a wire pressing block body 1501, a second cylinder assembly 1502 and a return spring 1503. The wire pressing block body 1501 is arranged on the fixing frame 1210 and is passed through by the rod-shaped part of the fixing frame 1210. The return spring 1503 is arranged between the wire pressing block body 1501 and the fixing frame 1210, so that the wire pressing block body 1501 and the second cylinder assembly 1502 tend to move away from the wire feeding platform 1223. The second cylinder assembly 1502 is arranged on the fixing frame 1210. On the side away from the return spring 1503, the second cylinder assembly 1502 is connected to the wire pressing block body 1501. The second cylinder assembly 1502 can drive the wire pressing block body 1501 to move toward the wire feeding platform 1223. When the two are in contact, they can press the wire. When the wire needs to be loosened, it is only necessary to stop driving the second cylinder assembly 1502, and the return spring 1503 will push the wire pressing block body 1501 away from the wire feeding platform 1223, thereby loosening the wire.

[0061] 3. The in-mold bending and punching device also includes a wire pressing block assembly, which is arranged at the end of the fixed frame away from the bending mold. The wire pressing block assembly can further fix the wire on the wire feeding platform and prevent the wire from sliding back.

[0062] 4. The wire feeding device includes a first drive unit, a second drive unit, a wire feeding platform, and a wire clamp assembly. The wire feeding platform is movably mounted on a fixed frame and, in conjunction with the first drive unit, enables reciprocating motion on the fixed frame to deliver the wire. The wire clamp assembly, mounted on the fixed frame, clamps the wire on the wire feeding platform to prevent it from slipping backward.

[0063] 5. The wire clamp assembly includes a wire clamp body, a first screw, and a first spring. The fixing frame is provided with a first screw hole. The first screw passes through the first spring, the wire clamp body, and the first screw hole of the fixing frame in sequence. The first spring is in a compressed state. The first eccentric shaft is connected to the wire clamp body. Under the action of the first spring, the wire clamp body tends to move toward the fixing frame, enabling it to clamp the wire. When the first eccentric shaft rotates to move the wire clamp body away from the fixing frame, the first spring is further compressed, and the wire is released from the clamping state. This structural arrangement allows the first screw to be adjusted at any time to achieve the optimal compression level of the first spring, resulting in a simple structure and easy maintenance.

[0064] 6. The first driving device includes a first cylinder and a first movable rod. The first movable rod is telescopically arranged in the first cylinder. The wire feeding platform is connected to the end of the first movable rod away from the first cylinder, so that the first driving device can drive the wire feeding platform to reciprocate on the fixed frame to complete the wire feeding action. The structure is simple and the control is convenient.

[0065] 7. The second drive device includes a motor, a transmission device, and an eccentric rod. The motor is fixed to a fixed frame, and the transmission device is fixed to the fixed frame. The motor and the eccentric rod are connected through the transmission device, so that the second drive device can drive the eccentric rod to rotate. The eccentric rod is equipped with a first eccentric shaft and a second eccentric shaft. The first and second eccentric shafts are eccentric in opposite directions and are respectively connected to the wire clamp assembly and the bending die. When the eccentric rod rotates, the wire clamp assembly and the bending die alternately open and close, resulting in a simple structure and easy control.

[0066] 8. The bending die includes a bending die body, a second screw and a second spring. The bending die body is provided with a second screw hole. The second screw passes through the second spring, the wire feeding platform and the second screw hole of the bending die body in sequence. The second spring is in a compressed state. The second eccentric shaft is connected to the bending die body. Under the action of the second spring, the bending die body tends to move toward the bending punch. When the second eccentric shaft rotates to make the bending die body move toward the bending punch, the bending die and the bending punch are tightened to achieve bending of the wire. Otherwise, the tightening state of the bending die body and the bending punch is released, allowing the wire to pass through. It only needs to control the eccentric rod to achieve wire clamping and wire bending, and the control is simple and convenient.

[0067] 9. The transmission device is a two-stage gear transmission, and the efficiency of energy transmission is high.

[0068] 10. The first component is also provided with a mold slide device, which can drive the first component to perform a slide action. That is, when the first component is separated from the second component, the mold slide device drives the first component to move perpendicular to the direction of separation of the first component and the second component. By performing separation movements in different directions simultaneously, the product can be easily removed from the mold. The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the principles of the present invention shall be included in the scope of protection of the present invention.
