Description

Technical Field

[0001] This disclosure relates to the field of cutting, and in particular to a multi-directional one-time cutting forming mold and cutting method. Background Technology

[0002] With the rapid development of AR / VR devices, consumer electronics, new energy vehicle components, and composite material products, product structures are gradually becoming lighter, more complex, and more precise. Workpiece contours often include side notches, beveled edges, irregular corners, and multi-directional structural features, placing higher demands on cutting precision and forming quality. Currently, the processing of such complex irregular workpieces typically employs laser cutting, ultrasonic cutting, and punching dies. Laser cutting can achieve complex contour processing, but its processing efficiency is limited by the cutting path, and heat-affected zones are prone to appear at the edges. Ultrasonic cutting is prone to edge deformation during the processing of some materials. Traditional punching dies mainly rely on the cooperation of upper and lower dies to complete the workpiece contour punching, and have high application value in mass production.

[0003] In existing technologies, while laser cutting can complete complex contour processing when forming irregularly shaped structures made of special materials, it suffers from problems such as edge carbonization and yellowing caused by heat-affected zones. In such cases, traditional cutting dies are used. However, these dies struggle to achieve multi-directional contour cutting of complex irregularly shaped workpieces in a single operation. Specifically, when a workpiece has side contours, inclined edges, and irregular structures in multiple directions, traditional punching dies typically only complete cutting in one direction, requiring multiple sets of dies or multiple processes to process different directional structures. Because each cutting process is independent, the workpiece needs repeated clamping and positioning during processing, easily leading to positional deviations between cutting areas in different directions, thus affecting overall contour accuracy and forming consistency. Furthermore, multi-process processing increases production cycle time and the number of dies required, reducing production efficiency and increasing production costs.

[0004] Therefore, a multi-directional one-time cutting mold and cutting method are proposed to solve the problem that multi-directional contours cannot be cut in one go. Summary of the Invention

[0009] The lower plate is connected to the clamping block by a spring. A connecting rod is provided on the lower plate. A connecting hole is provided on the clamping block corresponding to the connecting rod. The end of the connecting rod away from the clamping block passes through and extends into the connecting hole, and the connecting rod can move axially within the connecting hole.

[0010] The base plate is provided with a limiting post, and the length of the limiting post can be adjusted along the first direction. The limiting post is located between the base plate and the assembly plate and abuts against the assembly plate. A connecting plate is detachably provided between the base plate and the assembly plate.

[0011] A pushing unit is provided on the base plate, and the side cutter is mounted on the pushing unit. The cutting edge of the side cutter is adapted to the contour of the contact groove.

[0012] The pushing unit includes a slider, a guide rail, and a second cylinder. The guide rail is mounted on the base plate, the slider is slidably connected to the guide rail, the output end of the second cylinder is connected to the slider, and the side cutter is mounted on the slider.

[0013] The contact surface between the guide rail and the slider is set as a lubrication surface, and a receiving groove is formed on the lubrication surface, in which lubricating oil is placed.

[0014] A first groove is provided on the side of the support block near the upper cutter, corresponding to the storage area.

The elastic plate is configured to be in an unfolded state and a constricted state. The unfolded elastic plate abuts against the first groove and contacts the storage area.

[0015] The elastic plate has a pushing surface on one side of the storage area, and the edge corresponding to the pushing surface is set as a rounded edge.

[0016] A cutting method for a multi-directional one-time cutting forming mold, the cutting method being applied to the multi-directional one-time cutting forming mold as described above, the cutting method comprising the following steps: Step S1: First, place the workpiece in the storage area, and then move the clamping block and the bearing block relative to each other to position the workpiece. Step S2: Drive the side cutter to move along the placement area to cut the side contour of the workpiece; then drive the upper cutter and the lower cutter to move relative to each other to cut the main contour of the workpiece. Step S3: Remove the upper cutter, lower cutter, and side cutter from the storage area and reset them, so that the elastic plate contacts the workpiece, and move the workpiece out of the storage area, so that the elastic plate returns to the initial state in the second groove.

[0019] Compared with the prior art, this disclosure has the following beneficial effects: This disclosure provides a multi-directional one-time cutting forming mold and cutting method. After the workpiece is placed in the placement area, it is clamped and positioned by the relative movement between the upper and lower mold groups. Multiple cutting actions are completed in a stable positioning state. Simultaneously, the sequential movement of different cutters processes the side contours of the workpiece, allowing the workpiece to complete contour processing in different directions under the same clamping state. Because each cutting action is completed sequentially or collaboratively under the same clamping condition, the workpiece remains in a fixed position within the placement area during processing, reducing positional changes caused by repeated clamping and improving positional consistency between different contour processing. Furthermore, the coordinated setting of different directional cutting actions allows the contours of multiple directions of the workpiece to be completed in the same processing process, reducing the need for process switching caused by step-by-step processing, thus making the overall processing process more continuous. The problem of simultaneous forming of multi-directional structures mainly stems from the need for separate positioning or multiple processing of different directional contours, which easily leads to the accumulation of positional deviations during processing. This disclosure addresses this by completing clamping and positioning within the same placement area and performing multi-directional cutting, ensuring that contour processing in each direction is based on the same positioning datum, thereby avoiding the problem of error accumulation caused by multiple positioning. Furthermore, by using a unified processing space, cutting processes in different directions can be seamlessly connected under the same datum, thereby reducing the number of workpiece transitions between different processing stages and making the overall processing process more coherent and stable. Therefore, this disclosure enables one-time forming of multi-directional contours of a workpiece without adding extra clamping steps, and improves the overall consistency and stability of the processing.

For example, some operations / steps can be broken down, while others can be combined or partially combined; therefore, the actual execution order may change depending on the specific circumstances.

[0028] Example 1: Please see Figures 1-12 The multi-directional one-time cutting and forming mold in this embodiment includes an upper module 100 and a lower module 200; The upper module 100 includes a clamping block 110 and an upper cutter 120 that can move along a first direction; The lower module 200 includes a support block 230, a lower cutter 210 and several side cutters 220. The clamping block 110 and the support block 230 are distributed along a first direction. The lower cutter 210 is disposed on the support block 230 corresponding to the upper cutter 120. A storage area 300 is formed between the clamping block 110 and the support block 230. The storage area 300 is used to place the workpiece. The side of the clamping block 110 and the support block 230 opposite to the storage area 300 is provided as a contour surface 310, and the contour surface 310 is adapted to the contour of the workpiece. The lower cutter 210 is located within the coverage area of ​​the storage area 300. Several side cutters 220 are distributed around the support block 230. The side cutters 220 have a tendency to move towards the storage area 300, and some of the side cutters 220 are inclined towards the support block 230. The outer side of the support block 230 is provided with a contact groove 231 corresponding to the side cutter 220. The contact groove 231, the storage area 300 and the side cutter 220 are distributed from the inside to the outside. The side cutter 220 passes through the storage area 300 and contacts the contact groove 231, while the upper cutter 120 passes through the storage area 300 and contacts the lower cutter 210.

[0029] It should be noted that the first direction is the direction in which the clamping block 110 and the bearing block 230 move closer or further apart from each other, and the cutting movements of the upper cutter 120 and the lower cutter 210 are both carried out along the first direction.

[0030] In this embodiment, the workpiece is placed in the storage area 300. Both the clamping block 110 and the supporting block 230 have contoured surfaces 310 on their sides opposite the storage area 300, which are adapted to the workpiece's contour. After entering the storage area 300, the workpiece can obtain support and limitation matching its contour through the contoured surfaces 310. During cutting, the upper module 100 moves towards the lower module 200, and the clamping block 110 clamps and positions the workpiece, keeping it stable during the cutting process. During the cutting process, the upper cutting blade 120 and the lower cutting blade 210 cooperate to cut the corresponding area of ​​the workpiece, while the side cutting blade 220 cuts the side contour area of ​​the workpiece. Some of the side cutting blades 220 are inclined towards the supporting block 230, thus enabling the cutting of the workpiece's inclined edges or contours at specific angles, thereby completing the processing of the workpiece's contours in different directions.

[0031] In the specific working process, the workpiece is first placed in the placement area 300 and initially positioned by the contour surface 310 on the clamping block 110 and the bearing block 230. Then, the upper module 100 moves towards the lower module 200, and the clamping block 110 first contacts the workpiece and clamps and positions it. After the workpiece is in a stable state, the upper cutter 120, lower cutter 210, and side cutter 220 respectively cut the contour areas of the workpiece in different directions to form the required contour structure. After cutting is completed, the upper module 100 resets, and each cutter exits the cutting area, completing one cutting process.

[0032] The aforementioned structure, by providing multiple side cutters 220 around the support block 230, and cooperating with the upper cutter 120 and lower cutter 210 to form a cutting structure, enables the mold to simultaneously cut contours in different directions. Specifically, the upper cutter 120 and lower cutter 210 are used to form the cutting contour of the main body area of ​​the workpiece, while the side cutters 220 are used to form the side contour or inclined contour of the workpiece. Since the cutting structures in multiple directions are integrated within the same mold, the workpiece does not need to be re-clamped and repositioned between different processes to complete the cutting of contours in multiple directions, thereby reducing the accumulation of positional errors between different processes.

[0033] Simultaneously, the upper cutter 120, lower cutter 210, and side cutter 220 form an effective cooperative cutting relationship. The upper cutter 120 and lower cutter 210 are mainly used to form the cutting structure of the main contour area of ​​the workpiece, while the side cutter 220 is mainly used to form side contours, notch contours, or inclined contour structures. When the workpiece has contour features in multiple directions, different cutters can act on the corresponding areas respectively, allowing multiple contours to be processed within the same set of molds. Compared to the traditional method of processing with multiple sets of molds separately, the cutting structure in this disclosure can complete the processing of multiple contours under the same clamping conditions, thereby ensuring the positional relationship between different contour areas.

[0034] With the above-described structure, this embodiment can complete the cutting of complex irregular-shaped workpieces in multiple directions under a single clamping condition, reducing the positional deviation caused by repeated positioning in traditional multi-process machining, and improving the positional consistency between workpiece contours. Simultaneously, the integration of different cutting structures within the same mold reduces process transitions and the need for multiple mold sets for machining, thus solving the technical problem that existing cutting molds cannot achieve one-time forming and cutting of complex irregular-shaped workpieces in multiple directions.

[0035] Furthermore, in the above structure, since both the clamping block 110 and the bearing block 230 are provided with contoured surfaces 310 that adapt to the workpiece contour, the workpiece can achieve a relatively stable contour positioning effect after being placed in the placement area 300. This helps to reduce the rotation or offset of the workpiece during the cutting process, thereby improving the positional consistency between cutting areas in different directions. Simultaneously, a blade groove 231 is provided so that the side cutting blade 220 can enter the blade groove 231 after cutting, ensuring that the workpiece edge can be fully cut off and reducing the possibility of residual connecting material due to insufficient cutting stroke. At the same time, since some of the side cutting blades 220 are inclined towards the bearing block 230, they can directly cut the inclined edges or contours of the workpiece at specific angles without changing the workpiece placement angle or adding additional cutting processes to complete the oblique contour processing, thereby further improving the processing efficiency of complex irregularly shaped workpieces.

[0036] It should also be noted that the contoured surfaces 310 on the clamping block 110 and the bearing block 230 can be set according to the contour of the workpiece to be processed, so as to ensure that the workpiece can obtain a stable positioning effect within the placement area 300.

[0037] It is understood that the workpiece in this embodiment is not limited to a single structural form; it can be a plate-like part, a shell part, or a composite material part with side notches, inclined edges, irregular corners, stepped contours, or multi-directional contour features. For different workpiece contours, the contouring surfaces 310 on the clamping block 110 and the bearing block 230 can be adjusted accordingly to match the outer contour of the workpiece. When the workpiece is placed in the storage area 300, it can obtain support and restraint in multiple directions through the contouring surfaces 310, thereby reducing the possibility of positional changes during the cutting process. Simultaneously, the number, position, and tilt angle of the side cutting blades 220 can be adjusted according to the contour to be processed, enabling the mold to be suitable for processing different types of irregularly shaped workpieces, thereby improving the mold's applicability.

[0038] Example 2: The basic content is the same as in Example 1, except that: Please see Figures 1-8 In this embodiment, a base plate 240 is provided on the support block 230, the support block 230 is provided on the base plate 240, a guide sleeve 241 is provided on the base plate 240, a guide rod 131 is inserted into the guide sleeve 241, an assembly plate 130 is provided at the end of the guide rod 131 away from the guide sleeve 241, a connecting unit 140 is provided on the assembly plate 130, a first cylinder 170 is provided on the connecting unit 140, the output end of the first cylinder 170 is connected to the tool holder 121, a lower cutting blade 210 is provided on the tool holder 121, a clamping block 110 is provided on the connecting unit 140, the tool holder 121 is connected to the clamping block 110, and the tool holder 121 can be connected relative to the clamping block 110.

[0039] The aforementioned structure forms a guiding structure through the base plate 240, guide sleeve 241, and guide rod 131. During mold movement, the guide rod 131 can move along the guide sleeve 241, thereby constraining the movement trajectory of the assembly plate 130 and reducing the possibility of the assembly plate 130 deviating during movement. When the upper module 100 is subjected to uneven force, the cooperation between the guide rod 131 and the guide sleeve 241 can limit the tilting of the assembly plate 130, thereby improving the stability of the cutting process. Since the first cylinder 170, the tool holder 121, and the clamping block 110 are all mounted on the assembly plate 130, the guiding structure can provide a motion reference for both the clamping and cutting actions, enabling each component to maintain a relatively stable positional relationship as it approaches the workpiece, thus improving the cutting stability after workpiece positioning. At the same time, the first cylinder 170 drives the tool holder 121 to move relative to the clamping block 110, allowing the clamping and cutting actions to be controlled separately, thereby providing a structural basis for the subsequent processing of clamping followed by cutting. Meanwhile, during the resetting process of the upper module 100, the cooperation between the guide rod 131 and the guide sleeve 241 can also guide the return motion of the assembly plate 130, which helps to maintain the relative positional stability between the upper module 100 and the lower module 200.

[0040] During operation, the driving component moves the connecting unit 140, the clamping block 110, and the tool holder 121 towards the support block 230, while the guide rod 131 guides the movement along the guide sleeve 241. Once the clamping block 110 contacts the workpiece, it completes the clamping and positioning. The first cylinder 170 then continues to drive the tool holder 121, thereby driving the upper cutting blade 120 to complete the cutting action. After cutting, the first cylinder 170 drives the tool holder 121 to reset, and then the connecting unit 140 moves away from the support block 230, completing one cutting cycle.

[0041] It is understood that the driving component is used to drive the connecting unit 140 to move along the first direction. The driving component can be, for example, a hydraulic cylinder, an electric push rod, or other actuators that can achieve linear drive. The specific configuration of the driving component is a means well known to those skilled in the art, and will not be described in detail in this embodiment.

[0042] In the above process, the clamping block 110 and the upper cutter 120 respectively perform the positioning and cutting functions. When the clamping block 110 contacts the workpiece, the workpiece first achieves a stable positioning state; subsequently, the upper cutter 120 completes the cutting action under the drive of the first cylinder 170. By separating the positioning action from the cutting action, the cutting load is avoided from directly acting on the workpiece positioning process, thereby reducing workpiece displacement caused by force changes during the cutting process. At the same time, when there are certain fluctuations in the workpiece size, the clamping block 110 can still prioritize clamping and positioning, improving the mold's adaptability to workpiece dimensional tolerances.

[0043] Furthermore, the connecting unit 140 includes an upper plate 141, a column 142, and a lower plate 143 connected sequentially along a first direction. The upper plate 141 is connected to a driving member, and the driving member is used to drive the pressing block 110 to move toward the bearing block 230. The first cylinder 170 is disposed on the lower plate 143, and the pressing block 110 is elastically connected to the lower plate 143. The pressing block 110 can move relative to the lower plate 143.

[0044] In the above structure, when the connecting unit 140 moves towards the bearing block 230, the clamping block 110 can preferentially contact the workpiece and continue to maintain the clamping state under the action of elastic connection. Since the movement of the clamping block 110 and the tool holder 121 is not completely synchronized, after the workpiece is positioned, the tool holder 121 can continue to move under the drive of the first cylinder 170 and drive the lower cutting blade 210 to perform cutting. Through the above structure, the workpiece is in a relatively stable positioning state before the cutting begins, thereby reducing the situation where the workpiece moves due to force and affects the cutting position, which is beneficial to improving the positional consistency between cutting areas in different directions.

[0045] When the connecting unit 140 moves toward the bearing block 230, the clamping block 110 first contacts the workpiece and generates a relative displacement, and the elastic connection structure begins to compress. Subsequently, while the workpiece remains clamped, the tool holder 121 continues to move and drives the upper cutting blade 120 to perform cutting, thus forming a working process of first clamping and then cutting.

[0046] Furthermore, the lower plate 143 is connected to the clamping block 110 via a spring 150. A connecting rod 160 is provided on the lower plate 143, and a connecting hole 111 is provided on the clamping block 110 corresponding to the connecting rod 160. The end of the connecting rod 160 away from the clamping block 110 passes through and extends into the connecting hole 111, and the connecting rod 160 can move axially within the connecting hole 111.

[0047] In the above structure, when the clamping block 110 contacts the workpiece, the spring 150 can generate elastic deformation to adapt to possible dimensional differences or local contour changes on the workpiece surface. The cooperation between the connecting rod 160 and the connecting hole 111 restricts the movement direction of the clamping block 110, ensuring that the clamping block 110 maintains a predetermined movement trajectory even when it generates elastic displacement. Through the above settings, while ensuring that the clamping block 110 has buffering capacity, it avoids excessive swaying or positional deviation, thereby maintaining a relatively stable positioning state of the workpiece during the clamping process and providing a more reliable positioning basis for the subsequent cutting process. At the same time, the cooperation between the connecting rod 160 and the connecting hole 111 can also limit the clamping block 110, thereby reducing the possibility of the clamping block 110 detaching or excessively displacing during the repeated compression and rebound of the spring 150.

[0048] Furthermore, a limiting post 242 is provided on the base plate 240, and the length of the limiting post 242 can be adjusted along the first direction. The limiting post 242 is located between the base plate 240 and the assembly plate 130 and abuts against the assembly plate 130. A connecting plate 243 is detachably provided between the base plate 240 and the assembly plate 130.

[0049] In the above structure, when the assembly plate 130 moves along the first direction, the limiting post 242 can abut against the assembly plate 130, thereby limiting the end position of the movement of the assembly plate 130. By adjusting the length of the limiting post 242, the limiting position of the assembly plate 130 relative to the base plate 240 can be changed, allowing the mold to be adaptively adjusted according to different workpiece sizes, cutting depth requirements, or assembly needs, thereby improving the mold's adjustability and flexibility of use.

[0050] When processing workpieces of different specifications, the termination position of the assembly plate 130 can be changed by adjusting the length of the limiting post 242. The limiting post 242 can limit the maximum stroke of the assembly plate 130, thereby reducing the risk of over-pressing of the cutting structure due to excessive stroke of the driving component. After adjustment, the connecting plate 243 is used to fix the relative position between the assembly plate 130 and the base plate 240, thereby ensuring that the adjusted structure remains stable.

[0051] Meanwhile, the connecting plate 243 can establish a relatively stable connection between the assembly plate 130 and the base plate 240. When the mold needs adjustment, repair, or replacement of related parts, the assembly plate 130 and the base plate 240 can be quickly separated by disassembling the connecting plate 243. Under the function of the connecting plate 243, while ensuring the installation stability of the assembly plate 130, the assembly and maintenance convenience of the mold is improved, and the adjustment workload caused by overall disassembly is reduced, thus helping to maintain the stability of the mold's use.

[0052] Example 3: The basic content is the same as in Example 2, except that: Please see Figure 3 , Figure 4 and Figure 10 In this embodiment, a pushing unit 250 is provided on the base plate 240, and a side cutter 220 is provided on the pushing unit 250. The cutting edge of the side cutter 220 is adapted to the contour of the contact groove 231.

[0053] In the above structure, the side cutter 220 is mounted on the push unit 250, and the push unit 250 drives the side cutter 220 to move towards the placement area 300. Simultaneously, the cutting edge profile of the side cutter 220 matches the profile of the contact groove 231. After the side cutter 220 completes the cutting action, its cutting edge can enter the corresponding contact groove 231, thus enabling the side cutter 220 to complete the cutting process of the workpiece edge area. This structure provides the side cutter 220 with a movement path independent of the upper cutter 120 and the lower cutter 210, allowing the side cutter 220 to perform lateral cutting according to the processing requirements of the workpiece side profile, thereby providing a structural basis for processing complex irregular workpieces with different directional profiles. Since the side cutter 220 is independently driven by the push unit 250, it can perform corresponding directional cutting control according to the workpiece profile requirements, thereby improving the mold's adaptability to different irregular profile structures.

[0054] After the workpiece is positioned, the pushing unit 250 drives the side cutter 220 to move towards the placement area 300. The side cutter 220 passes through the corresponding area of ​​the workpiece and enters the contact groove 231 to complete the lateral cutting. After cutting, the pushing unit 250 drives the side cutter 220 out of the contact groove 231 and back to its initial position. During the cutting process, the cutting edge of the side cutter 220 matches the contour of the contact groove 231, which can reduce the risk of collision during the process of the side cutter 220 entering the contact groove 231.

[0055] It should be noted that the pushing unit 250 is used to drive the side cutter 220 to reciprocate in a predetermined direction, so as to realize the cutting of the side contour area of ​​the workpiece by the side cutter 220. The pushing unit 250 can be, for example, a hydraulic cylinder, an electric push rod or other actuators capable of linear drive. The specific configuration of the pushing unit 250 is a means well known to those skilled in the art, and will not be described in detail in this embodiment.

[0056] Furthermore, the pushing unit 250 includes a slider 251, a guide rail 253 and a second cylinder 252. The guide rail 253 is mounted on the base plate 240, the slider 251 is slidably connected to the guide rail 253, the output end of the second cylinder 252 is connected to the slider 251, and the side cutter 220 is mounted on the slider 251.

[0057] In the above structure, when the second cylinder 252 is activated, it drives the slider 251 to move along the guide rail 253, and causes the side cutter 220 to move towards the placement area 300. Since the movement of the side cutter 220 is guided and constrained by the guide rail 253, the side cutter 220 can approach the corresponding area of ​​the workpiece along a predetermined trajectory, which helps to reduce the offset generated during the movement, improve the correspondence accuracy between the side cutter 220 and the contact groove 231, and maintain good stability of the lateral cutting action.

[0058] Furthermore, the contact surface between the guide rail 253 and the slider 251 is set as a lubrication surface 254, and a receiving groove 255 is provided on the lubrication surface 254, and lubricating oil is placed in the receiving groove 255.

[0059] In the above structure, when the slider 251 reciprocates along the guide rail 253, the lubricating oil can be distributed in the contact area between the slider 251 and the guide rail 253, thereby reducing the frictional resistance between them. This structure helps reduce wear on the slider 251 during its movement, maintains the smoothness and stability of the slider 251's movement along the guide rail 253, and thus improves the operational reliability of the push unit 250, ensuring the side cutter 220 can continuously and stably complete the lateral cutting action. Simultaneously, the lubricating oil slows down the wear rate between the guide rail 253 and the slider 251, thus helping to maintain the motion accuracy of the side cutter 220 during long-term use.

[0060] Furthermore, during the reciprocating motion of the side cutter 220, the guide rail 253 and the slider 251 form a stable guiding relationship, enabling the side cutter 220 to approach the workpiece's cutting area along a predetermined trajectory. Since the side cutter 220 needs to enter the contact groove 231 during operation, the stability of its motion trajectory directly affects the cutting position accuracy. Constraining the side cutter 220 with the guide rail 253 reduces the possibility of swaying or tilting during movement, thus helping to maintain the correspondence between the side cutter 220 and the contact groove 231 and improving the stability of the lateral cutting action.

[0061] Example 4: The basic content is the same as in Example 1, except that: Please see Figure 5 , Figure 11 and Figure 12 In this embodiment, a first groove 232 is provided on the side of the support block 230 near the upper cutter 120 corresponding to the storage area 300, and a second groove 122 is provided on the upper cutter 120 corresponding to the first groove 232. An elastic plate 123 inclined towards the first groove 232 is provided in the second groove 122. The elastic plate 123 is configured to be in an unfolded state and a constricted state. The unfolded elastic plate 123 abuts against the first groove 232 and contacts the storage area 300, and the constricted elastic plate 123 is completely constricted in the second groove 122.

[0062] During the cutting process, the clamping block 110 and the supporting block 230 approach each other and clamp and position the workpiece. At this time, the elastic plate 123 is restricted by the relative positional relationship between the clamping block 110 and the supporting block 230 and remains in a contracted state, located in the second groove 122, thereby preventing the elastic plate 123 from extending and affecting the workpiece positioning and cutting action. After the side cutter 220 completes the lateral cutting and the upper cutter 120 and lower cutter 210 complete the main body contour cutting, the upper cutter 120 resets upward with the upper module 100. During the reset process, when the elastic plate 123 moves to the corresponding position of the first groove 232, the first groove 232 provides clearance space for the elastic plate 123 to change from a contracted state to an unfolded state, so that the elastic plate 123 can unfold on its own elasticity and push the cut workpiece out of the storage area 300 through the pushing surface 124, thereby facilitating the removal of the workpiece. The workpiece is automatically pushed away from the storage area 300 by the elastic plate 123, which can reduce the situation where the workpiece is stuck in the storage area 300, thereby reducing the possibility of interference during the next feeding and improving the stability of continuous mold processing.

[0063] It should be noted that the extended state of the elastic plate 123 refers to the state in which the elastic plate 123 extends at least partially out of the second groove 122 and is in contact with the storage area 300; the constricted state of the elastic plate 123 refers to the state in which the elastic plate 123 is completely contained inside the second groove 122 and does not extend into the storage area 300.

[0064] During operation, after the workpiece is positioned, the side cutter 220 first cuts the side contour, and then the upper cutter 120 and lower cutter 210 cut the main body contour. During the cutting stage, the elastic plate 123 remains in a contracted state and is located within the second groove 122. After cutting is completed, the upper cutter 120 returns to its original position. When the elastic plate 123 moves to the corresponding area of ​​the first groove 232, the elastic plate 123 returns to its unfolded state and contacts the workpiece, thereby pushing the workpiece away from the storage area 300.

[0065] As is known, in traditional cutting dies, the workpiece usually remains in the cutting area after cutting, requiring manual labor or an additional ejection mechanism to retrieve it. If the workpiece does not leave the cutting area in time, it can easily affect the next feeding process. In the above structure, by switching between the unfolded and retracted states of the elastic plate 123, the elastic plate 123 can automatically contact the workpiece after cutting and push the workpiece away from the placement area 300. Since this ejection action is achieved by utilizing the structural state change during the resetting process of the upper cutter 120, the workpiece ejection process can be completed without adding an additional independent drive mechanism, improving the convenience of continuous die operation while ensuring structural compactness.

[0066] Furthermore, a pushing surface 124 is formed on one side of the elastic plate 123 corresponding to the storage area 300, and the edge corresponding to the pushing surface 124 is set as an arc edge 125.

[0067] In the above structure, when the pushing surface 124 contacts the workpiece and pushes the workpiece to move, the arc edge 125 can prevent the edge of the pushing surface 124 from directly acting on the workpiece surface in a sharp state, reducing the possibility of the workpiece being scratched, crushed, or damaged during the removal of the storage area 300. After the workpiece is pushed out, when the upper cutter 120 continues to reset upward, the arc edge 125 gradually contacts the clamping block 110. Since the elastic plate 123 is inclined towards the first groove 232, the force generated after the arc edge 125 contacts the clamping block 110 can be converted into a contraction movement of the elastic plate 123 towards the second groove 122, and a guiding effect is applied to the elastic plate 123 during the relative movement, so that the elastic plate 123 gradually contracts towards the second groove 122 and is finally re-stored in the second groove 122, preventing the elastic plate 123 from continuously extending into the storage area 300 and affecting the next feeding and cutting.

[0068] During the resetting process of the upper cutter 120, the arc edge 125 can form a smooth contact with the clamping block 110, and guide the elastic plate 123 to gradually converge towards the second groove 122 during the relative movement, thereby avoiding the elastic plate 123 from being stuck in the unfolded state, improving the resetting reliability of the elastic plate 123, and providing a guarantee for the mold to continuously carry out the next cutting operation.

[0069] In summary, in a complete work cycle, the workpiece is first placed in the storage area 300 and positioned by the contour surface 310; then, the clamping block 110 clamps and positions the workpiece; subsequently, the side cutter 220, upper cutter 120, and lower cutter 210 complete the cutting processing of their respective areas; after cutting, the upper cutter 120 gradually resets, the elastic plate 123 changes from a contracted state to an unfolded state and pushes the workpiece away from the storage area 300; after the workpiece leaves, the arc edge 125 cooperates with the clamping block 110 to make the elastic plate 123 re-contract into the second groove 122, thus returning to the initial standby state. Through the above cyclic process, the mold can continuously complete the actions of workpiece placement, positioning, cutting, exporting, and resetting, forming a complete automated cutting cycle, which is beneficial to improving the working stability and processing efficiency of the mold in continuous production.
