Traditionally, side blanking structures typically require significant installation space, which contradicts the space constraints often encountered in actual die design. While existing floating block blanking structures save space to some extent through their mounting platform design, they still suffer from insufficient blanking stability and structural complexity. Especially when processing complex stamped parts, conventional side blanking structures struggle to simultaneously meet the dual requirements of space compactness and blanking reliability. Die designers frequently face the technical challenge of achieving stable and reliable side blanking within limited spaces. Utility Model Content

[0058] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0059] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0060] In existing technologies, the lateral blanking structure of cold stamping dies typically employs a direct lateral drive method, requiring a separate horizontal guiding mechanism and drive unit. This structure results in the blanking device occupying a large space on the side of the die, often leading to interference between the blanking mechanism and other die components in stamping operations with narrow lateral spaces. Particularly in automotive body panel stamping dies, when multi-station punching is required on the sidewalls, traditional blanking structures struggle to accommodate sufficient blanking force transmission mechanisms within a limited space.

[0061] To address the aforementioned issues, designers discovered that while the vertical space was relatively ample, directly utilizing vertical motion for lateral pressure would increase the structural height. After numerous experiments, they found that converting vertical motion into horizontal motion using a ramp transmission mechanism effectively utilized the mold's longitudinal space. Further research revealed that employing a double-wedge block structure allowed for a spatially staggered arrangement of the driving and actuating components, thereby optimizing the structural volume in three-dimensional space. Ultimately, it was determined that the driving block and slider would be positioned in the grooves on both sides of the support base, with motion conversion achieved through the wedge-shaped ramp.

[0062] In some of these embodiments, such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this application proposes a side-pressure material structure for a cold stamping casting mold, including a support base 100 fixed on the lower mold, a wedge-shaped drive block 200 fixed on the upper mold, a wedge-shaped slider 300, a side-pressure fixing seat 400, and a side-pressure punch mechanism 500. The wedge-shaped drive block 200, which can move up and down, is disposed in a groove at the left end of the support base 100, and the wedge-shaped slider 300, which can move left and right, is disposed in a groove at the right end. The first wedge-shaped inclined surface 202 on the lower right side wall of the wedge-shaped drive block 200 is arranged to cooperate with the second wedge-shaped inclined surface 302 at the left end of the wedge-shaped slider 300. The side-pressure fixing seat 400 and the side-pressure punch mechanism 500 are disposed at the right end of the wedge-shaped slider 300.

[0063] The support base 100 is the basic component that supports the motion conversion mechanism. It can be implemented using a casting with left and right grooves, which respectively accommodate the wedge-shaped drive block 200 and the wedge-shaped slider 300, forming a spatially separated layout. The wedge-shaped drive block 200 is a motion conversion component with an inclined working surface 202. It can be implemented using a steel block with a 30-60° slope, and obtains vertical driving force by bolting to the upper mold. The wedge-shaped slider 300 is an actuator with a reverse inclined surface, and can be implemented using a guide slider with a matching inclined surface, whose angle complements that of the wedge-shaped drive block 200. The side pressure fixing seat 400 is the mounting base that connects to the pressure actuator 500. It can be composed of a multi-layered plate structure and is fixed to the right side of the slider by bolts to achieve force transmission.

[0064] In use, when the upper mold drives the wedge-shaped drive block 200 downwards, the first wedge-shaped inclined surface 202 and the second wedge-shaped inclined surface 302 make sliding contact. Since the drive block is constrained by the left groove of the support base 100 and can only move vertically, its inclined surface pushes the wedge-shaped slider 300 to move horizontally to the right along the right groove. This motion conversion transforms the vertical mold-closing action into the lateral feed of the side-pressing punch mechanism 500, avoiding the independent drive space required by traditional side-pressing mechanisms. The wedge-shaped slider 300 directly transmits the horizontal displacement to the punch mechanism 500, forming a compact force transmission chain. The nested arrangement of each component within the groove of the support base 100 creates a three-dimensional layout between the drive mechanism and the actuator.

[0065] Through the above technical solution, this application achieves reliable material pressing function under conditions of limited lateral space in the mold. The wedge mechanism 200 is driven by the opening and closing motion of the mold body, eliminating the space required for a separate drive unit. The inclined plane transmission structure converts vertical motion into horizontal pressing action, allowing the pressing mechanism to be fully embedded within the mold body contour. The double-groove design of the support base 100 achieves a reasonable spatial arrangement of the drive and execution components, maintaining a compact overall structure in both the longitudinal and lateral directions. This structure is particularly suitable for the sidewall punching station of automotive body panel molds, enabling multi-position lateral pressing operations without increasing the overall mold size.

[0066] In some of these embodiments, such as Figure 6 and Figure 7 As shown, this application further proposes a support base 100 including a base body 110, side baffles 120, and upper baffles 130. The bottom of the base body 100 is detachably bolted to the lower mold, and its top has a first through groove 111 extending from left to right. A receiving groove 112 is formed at the bottom left end of the first through groove 111, used to install the wedge-shaped slider 300 and the wedge-shaped drive block 200, respectively. The side baffles 120 have an inverted U-shaped plate structure, and their two ends are detachably bolted to the outer side wall of the left end of the base body 100, used to limit the left side wall of the wedge-shaped drive block 200. There are two upper baffles 130, which are detachably bolted to the base body 110 on both sides of the first through groove 111, used to limit the wedge-shaped drive block 300 within the first through groove 111.

[0067] The base body 110 refers to the base structure that supports the moving components. Specifically, it can be a casting with a through first sliding groove 111. A receiving groove 112 at the bottom left end of the sliding groove is used to match the extension structure of the drive block. The side baffle 120 is a limiting component that constrains the horizontal displacement of the wedge-shaped drive block 200. Specifically, it can be an inverted U-shaped steel plate fixed with bolts. The upper baffle 130 is a limiting mechanism that ensures the wedge-shaped slider 300 only slides left and right. Specifically, it can be a split steel plate symmetrically installed on both sides above the first sliding groove 111 to limit the top of the wedge-shaped drive block 300.

[0068] Specifically, the base body 110 is bolted together to allow for quick assembly and disassembly from the lower mold. A first groove 111 on its top forms a transverse guide rail, and a left-end receiving groove 112 and the extended structure at the bottom of the drive block 200 form a vertical movement space. An inverted U-shaped side baffle 120 is fixed to the outer left wall of the base body 110 by bolts on both sides, providing rigid restraint on the left side wall of the wedge-shaped drive block 200, preventing horizontal displacement but allowing vertical sliding. Two sets of upper baffles 130 are symmetrically installed above the edges of the first groove 111 and bolted to the base body 100. This base body 100 features modular assembly characteristics, enabling motion trajectory control of the wedge-shaped drive block 200 and the wedge-shaped slider 300 within a limited space.

[0069] It is worth noting that, such as Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, this application further proposes that the top of the left end of the base body 100, the first slide groove 111, and the bottom of the receiving groove 12 are arranged inclined downwards to the right, with an inclination angle of 0-45° relative to the horizontal plane. The inclined downward arrangement means that the top of the left end of the base body 100 and the bottom of the first slide groove 111 form a continuous inclined surface, allowing the wedge-shaped drive block to slide along the inclined surface during vertical movement, thereby driving the punch 540 on the side-pressing punch mechanism 500 to perform side pressing. The inclination angle of 0-45° refers to the angle range between the inclined surface and the horizontal plane, preferably 0-30°, more preferably 10-15°, and the specific angle value can be controlled by adjusting the processing parameters.

[0070] In some of these embodiments, such as Figure 4 , Figure 8 and Figure 9 As shown, this application further proposes a side pressure structure for a cold stamping casting mold, wherein the wedge-shaped drive block 200 includes an integrally formed drive body 201, a connecting ear plate 203, a drive extension block 204, and a limiting block 205. The right side wall of the drive body 201 is provided with a first wedge-shaped inclined surface 202 with an inclination angle of 30-60°; the connecting ear plate 203 is provided on both sides of the top of the drive body 201 and is connected to the upper mold bolt through mounting holes; the drive extension block 204 is located at the bottom of the drive body 201 and corresponds to the receiving groove 112 of the support base 100; the limiting block 205 is C-shaped, provided on both sides of the drive body 201 and fitted into the limiting inclined groove 305 of the wedge-shaped slider 300.

[0071] The drive body 201 and the drive extension block 204 form a continuous first wedge-shaped inclined surface 202 on one side wall, which is used to cooperate with the wedge-shaped slider 300. The connecting ear plate 203 is bolted to the upper mold through multiple holes spaced apart on it to achieve uniform load distribution. The C-shaped structure of the limiting block 205 cooperates with the limiting groove 305 in an interlocking manner, so as to limit the wedge-shaped slider 300 during the up and down lifting process and prevent the wedge-shaped slider 300 from shifting laterally during the front and rear pressing process. The slope of the first wedge-shaped inclined surface 202 is preferably 40-50°, and preferably 45°.

[0072] Specifically, when the upper mold is pressed down, the drive body 201 pushes the wedge-shaped slider 300 to move laterally via the first wedge-shaped inclined surface 202. During its vertical movement, the drive extension block 202 avoids contact with the bottom of the sliding groove 111 at the left end when it moves down, thus preventing it from affecting the pressure measurement. The limiting block 205 moves along the inclined trajectory of the limiting groove 305, simultaneously constraining the longitudinal offset trend of the slider during its lateral movement.

[0073] In some of these embodiments, such as Figure 4 , Figure 10 and Figure 11 As shown, this application further proposes a wedge-shaped slider 300 including a slider body 301, a slider guide block 303, a limiting stop block 304, a limiting inclined groove 305, and a spring mounting groove 306. The left side wall of the slider body 301 is configured as an inclined second wedge-shaped inclined surface 302, the slider guide block 303 is laterally disposed at the lower end of both side walls of the slider body 301, the limiting stop block 304 is disposed at the bottom left end of the slider body 301, the limiting inclined groove 305 is inclinedly disposed at the upper end of both side walls of the slider body 301, and the spring mounting groove 306 is opened at the middle of the right side wall of the slider body 301.

[0074] The second wedge-shaped inclined surface 302 refers to the inclined working surface that contacts the wedge-shaped drive block 200. Specifically, it can be implemented with an inclined angle range of 30-60°. This angle range ensures effective transmission of driving force while avoiding structural interference. Preferably, an inclined angle of 40-50° is used, and more preferably, 45°. The slider guide block 303 refers to the transverse protrusion structure located on both sides of the slider body 301. Specifically, it can be implemented with a rectangular cross-section matching the slide groove of the support base 100, forming a sliding pair through its cooperation with the slide groove. The limiting stop block 304 refers to the protrusion structure located at the bottom of the slider body 301. Specifically, it can be implemented with an inverted trapezoidal cross-section matching the receiving groove 112 at the bottom of the support base 100, used to limit the stroke of the slider body 301 and form part of the inclined transition.

[0075] The limiting groove 305 refers to the inclined groove with an open top, located on both sides of the slider body 301. Specifically, it can be implemented with an inclination angle of 30-60° that matches the limiting block 205 of the drive block, forming a dynamically compensated sliding pair. The spring mounting groove 306 refers to the groove structure used to install the return spring 530. Specifically, it can be implemented with a 45° inclined figure-eight groove structure layout, achieving staggered installation of the two springs within a limited space.

[0076] Specifically, when the upper mold drives the wedge-shaped drive block 200 downward, the first wedge-shaped inclined surface 202 and the second wedge-shaped inclined surface 302 contact to generate a lateral force. The slider guide block 302 moves laterally along the groove of the support base 100, maintaining a linear motion trajectory through the constraint of the upper baffle 130. The limit stop block 304 slides within the receiving groove 112, forming a mechanical limit at the end of its stroke. The limit locking block 205 of the drive block 200 slides along the limit inclined groove 305, compensating for motion trajectory deviations through a matching tilt angle. The return spring 530 is compressed and stores energy within the spring mounting groove 306, pushing the slider body 300 to reset when the driving force is released. The various structural elements work together through angle matching and spatial layout to achieve stable sliding control and precise reset within a limited space.

[0077] In some of these embodiments, such as Figure 3 , Figure 4 , Figures 12 to 15 As shown, this application further proposes a side pressure fixing seat 400 comprising a pressure fixing plate 410, a pressure clamping plate 420 and at least one pressure pad 430 arranged sequentially from right to left. The pressure fixing plate 410, the pressure clamping plate 420 and at least one pressure pad 430 are detachably fixed to the right side wall of the wedge slider 300 by a number of bolts, and a side pressure punch mechanism 500 is limited and installed in the installation cavity inside.

[0078] The pressure plate 410 is a base support plate used to fix the side-pressure punch mechanism 500, and its guide hole 411 is used to constrain the movement trajectory of the side-pressure block 510. The pressure clamping plate 420 is an intermediate connecting plate used to limit the installation of the side-pressure punch mechanism 500. Specifically, it can be a steel plate with a first figure-eight through hole 421, which allows the installation and movement of the return spring. The pressure pad 430 is an addable and subtractable plate used to adjust the installation length of the side-pressure punch mechanism 500. Specifically, it can be a steel plate with a second figure-eight through hole 431, and the overall thickness can be changed by stacking the plates to adapt to different punching pressure requirements. The mounting cavity is the internal cavity formed by the pressure block guide hole 411, the first figure-eight through hole 421, the second figure-eight through hole 431, etc., used to accommodate and limit the movement of the side-pressure punch mechanism 500.

[0079] The pressure fixing plate 410, pressure clamping plate 420, and pressure pad 430 are stacked sequentially from right to left, forming a compact horizontal installation structure. The pressure fixing plate 410, pressure clamping plate 420, and pressure pad 430 are bolted to the right side wall of the wedge-shaped slider 300, with their pressure block guide holes 411 limiting the movement of the side pressure block 510. The pressure clamping plate 420 is stacked on the left side of the pressure fixing plate 410, and its first figure-eight through hole 421, together with the second figure-eight through hole 431 of the pressure pad 430, forms the installation channel for the return spring 530. Depending on production needs, the longitudinal depth of the installation cavity can be adjusted by increasing or decreasing the number of pressure pads 430, thus adapting to different sizes of side pressure punch mechanisms 500. The layers are bolted together to form a rigid overall structure, while allowing for layered disassembly for component replacement or maintenance.

[0080] As a preferred option, such as Figure 12 , Figure 13 , Figure 14 and Figure 15 As shown, this application further proposes that the pressure fixing plate 410 has a pressure block guide hole 411 that runs through the front and back in the middle, and the top and bottom of the left end of the pressure block guide hole 411 are respectively provided with pressure block limiting grooves 412 for limiting the installation of the side pressure block 510 on the side pressure punch mechanism 500; the pressure clamping plate 420 and the pressure pad plate 430 are respectively provided with a first figure-eight through hole 421 and a second figure-eight through hole 431 that run through the front and back, and two return springs 530 on the side pressure punch mechanism 500 are movably arranged in the first figure-eight through hole 421 and the second figure-eight through hole 431.

[0081] The guide hole 411 for the pressure block refers to a through-hole extending along its front-back direction. It can be implemented using a rectangular cross-section channel, with its inner wall forming a clearance fit with the side pressure block 510, providing a linear sliding trajectory for the side pressure block 510. The pressure block limiting groove 512 refers to the groove structure located at the top and bottom of the left end of the guide hole 411. By cooperating with the side pressure stop 512 on the side pressure block 510, it limits the maximum travel of the side pressure block 510 within the guide hole 411. The figure-eight shaped through hole refers to a special hole type with two interconnected circular holes. The center distance between the two circular holes matches the installation spacing of the return spring 530, ensuring the spring's extension and contraction space while forming a double guiding constraint on the spring axis.

[0082] Specifically, the pressure plate establishes a reference path for the side pressure block to slide back and forth through the pressure block guide hole. The cooperation between the pressure block limiting groove and the side pressure stop restricts the movement freedom of the side pressure block to a single horizontal direction. The figure-eight through-hole structure formed by the combination of the pressure clamp plate and the pressure pad plate causes the return spring to deform along a predetermined axis direction when compressed, avoiding deviation of the return trajectory caused by lateral bending of the spring. The corresponding arrangement of the two sets of figure-eight through holes provides continuous guidance for the return spring, ensuring that the spring maintains a stable direction of extension and contraction within a limited space.

[0083] In some of its embodiments, such as Figure 4 , Figure 5 , Figure 16 , Figure 17 and Figure 18 As shown, this application further proposes a side-pressure punch mechanism 500 including a side-pressure block 510, a spring guide rod 520, a return spring 530, and a punch 540. The side-pressure block 510 can be slidably embedded in the pressure block guide hole 411 at the front end of the side-pressure fixing seat 400. The top and bottom of the front end are respectively provided with side-pressure stops 512 that cooperate with the pressure block limiting groove 412. One end of the spring guide rod 520 is fixedly installed on the left side wall of the side-pressure block 510, and a return spring 530 is sleeved on it. The two ends of the return spring 530 are respectively abutted and connected to the side-pressure block 510 and the wedge slider 300. There are two punches 540, which are respectively transversely inserted into the punch guide holes 511 at the left and right ends of the side-pressure block 510. The left end passes through the corresponding through holes on the pressure fixing plate 410, the pressure clamping plate 420, and the pressure pad plate 430 and abuts and connects to the wedge slider 300.

[0084] The side pressure block 510 refers to a pressure actuator with a lateral sliding function. Specifically, it can be implemented using a rectangular metal block in conjunction with a sliding guide structure. The sliding range is limited by the side pressure block 510 engaging with the limiting groove 412 within the guide hole 411. The spring guide rod 420 is a rod-shaped component used to constrain the extension and retraction direction of the return spring 530. Specifically, it can be a cylindrical steel rod threaded onto the side pressure block 510, achieving an elastic return function by fitting a spring. The punch guide hole 511 is a through hole penetrating both sides of the side pressure block 510. Specifically, it can be a circular hole structure used to guide the lateral movement of the punch 540.

[0085] Specifically, when the side-pressure block 510 slides left and right within the guide hole 411, the cooperation between the side-pressure stop block 512 and the limiting groove 412 prevents it from dislodging, ensuring the stability of the pressing stroke. The return spring 530, sleeved on the spring guide rod 520, compresses or extends along the movement direction of the wedge slider 300, causing the wedge slider 300 and the side-pressure block 510 to automatically reset after pressing. The two punches 540 pass through the guide holes 511 on both sides of the side-pressure block 510, with their left ends directly contacting the wedge slider 300. When the wedge slider 300 moves, it pushes the punches 540 to move laterally to perform the pressing action. The clearance fit between the punch guide hole 511 and the punches 540 ensures freedom of movement while limiting their offset.

[0086] Furthermore, such as Figure 16 , Figure 17 and Figure 18 As shown, this application further proposes that the spring guide rod 520 and the return spring 530 are arranged in two sets, staggered left and right, and installed in the figure-eight shaped through holes within the side pressure fixing seat 400. The staggered left-right arrangement means that the two sets of spring guide rods 520 and return springs 530 are arranged asymmetrically in the horizontal direction. The figure-eight shaped through hole refers to a continuous through-hole formed by the first figure-eight shaped through hole 421 and the second figure-eight shaped through hole 431, which provides irregular installation space for the staggered spring assembly.

[0087] Specifically, when the side-pressing punch mechanism 500 performs its pressing action, its two sets of staggered return springs 530 are independently compressed along their respective axial directions within the figure-eight shaped through-hole. This left-right staggered arrangement creates a complementary relationship between the installation positions of the two sets of springs in the lateral space, effectively reducing the lateral span required for a traditional side-by-side arrangement of two springs. The special contour of the figure-eight shaped through-hole provides precise radial restraint for the two sets of return springs 530, and its continuous hole wall structure ensures that the deformation space during spring compression is not interfered with. This combined design, through the synergistic effect of spatial stagger and irregularly shaped channels, maintains the stability of the dual-spring system while keeping the mechanism width within 70% of that of a traditional structure.

[0088] In addition, such as Figure 3 , Figure 4 and Figure 18As shown, this application further proposes a technical solution where the extension / retraction direction of the return spring 530 and the punching direction of the punch 540 are consistent with the sliding direction of the wedge slider 300. Specifically, the extension / retraction direction of the return spring 530 refers to the direction of its movement trajectory when compressed or extended; the punching direction of the punch 540 refers to the direction of the movement trajectory where the punch applies pressure to the workpiece, ensuring that the punching action is synchronized with the lateral movement of the slider. The sliding direction of the wedge slider 300 refers to the linear motion path generated by the slider under the action of the wedge drive block 200. Specifically, it can be defined by a guide rail or a groove to limit the single-degree-of-freedom motion trajectory, ensuring that the slider moves only along a preset direction.

[0089] Specifically, during the mold closing process, the wedge-shaped slider 300 undergoes lateral sliding under the action of the wedge-shaped drive block 200. At this time, the return spring 530 extends and retracts in the same direction to buffer the impact force when the side pressure block 510 contacts the workpiece. The punch 540 then directly applies vertical pressure along the sliding direction to punch the workpiece. The extension and retraction direction of the return spring 540 is consistent with the sliding direction of the slider, eliminating the lateral component force caused by the lateral deformation of the spring. The punching direction of the punch 540 is consistent with the sliding direction, avoiding the need for a guide structure to avoid deviation of the punch's movement trajectory.

[0090] In summary, combining Figures 1 to 18 As shown, a novel side-clamping structure for cold stamping casting dies is provided. Stable lateral clamping is achieved through the inclined surface cooperation of the wedge-shaped drive block 200 and the wedge-shaped slider 300. Combined with a detachable modular design to optimize space layout, this solution addresses the problems of large space occupation and insufficient stability of traditional side-clamping structures without adding processes or increasing the workload of a single die. This die side-clamping structure can be used for floating block-style clamping or as a hanging platform to save space. It not only significantly reduces the clamping space, facilitating side punching and edge trimming designs in space-constrained environments, but also greatly reduces development costs.
