Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a segmented molding mold for an air fryer. Background Technology

[0002] The main body of an air fryer is typically a cylindrical structure with a top wall and side walls. The inner side of the shell usually features thickened areas, clips, or steps at the junction of the top and side walls, creating a complex area at the wall thickness boundary. After injection molding, the shell needs to be ejected from the mold core. Currently, the conventional ejection method involves arranging multiple small-diameter ejector pins in the mold, which directly act on the inner surface of the shell to achieve ejection. However, the small ejection area of ​​the small ejector pins results in concentrated ejection force, making it prone to whitening or deformation on the shell surface, especially at the wall thickness boundary where material is concentrated and geometric abrupt changes occur, making it more sensitive to stress and increasing the risk of deformation.

[0003] Meanwhile, due to the spatial constraints and directional limitations of the forming surface in the wall thickness junction area, small ejector pins are often difficult to place directly at this junction. This is because the shell typically needs to form multiple surfaces with different orientations simultaneously at this location, such as a local horizontal top surface and a vertical side wall surface. However, the ejector pin end face has a simple shape and can only mate with simple planes. If forcibly placed at the junction, it will not only fail to match the required multi-directional forming surfaces but will also damage the forming surface at that location, causing product defects. Therefore, in practical solutions, the ejector pins must be moved to other planar positions far away from the wall thickness junction area, resulting in an unreasonable ejection point layout, unbalanced ejection action, and further exacerbating the shell's deformation tendency at the junction.

[0004] Furthermore, from the perspective of forming surfaces in multiple directions, while existing molds utilize angled ejectors for lateral core pulling and ejection, the working face of a conventional angled ejector is often a single forming surface, participating in the forming of only one direction, such as forming only the sidewall or undercut surface. It cannot simultaneously form the top and sidewall surfaces arranged at an angle. For applications like the body shell of an air fryer, which require simultaneous forming of multiple surfaces at the wall thickness junction and smooth ejection, existing angled ejector structures are insufficient. They typically still rely on cores combined with multiple sets of ejector pins and slides, resulting in complex mold structures, and the ejection effect and forming quality at the wall thickness junction remain unsatisfactory. Utility Model Content

[0005] The purpose of this invention is to provide a segmented air fryer molding mold that solves the problem that existing integral molds are prone to ejection jamming or product damage during demolding due to the complex product structure, thus improving molding quality and production efficiency.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a segmented air fryer forming mold, comprising an upper mold base and a lower mold assembly, wherein the lower mold assembly includes a lower mold base located below the upper mold base, a core is provided on the lower mold base, and a cavity for forming a product is defined between the core and the upper mold base; the upper mold base is provided with a first insert forming mechanism for forming a first area of ​​the product and a second insert forming mechanism for forming a second area of ​​the product; the lower mold assembly is provided with a product ejection mechanism; the lower mold assembly further includes a support base located below the lower mold base, wherein the support base is slidably configured to linearly displace in a direction approaching or away from the lower mold base. The lifting plate and the product ejection mechanism include an inclined ejector. One end of the inclined ejector passes through the lower mold base and the core in sequence, and its end forms at least two forming surfaces facing different directions, which respectively form the top surface and side wall of the core, thereby constituting the forming surfaces on the top surface and side wall of the cavity. The other end of the inclined ejector is slidably connected to the lifting plate. An inclined surface is formed on the inclined ejector, and an inclined guide surface is formed on the core corresponding to the position of the inclined surface. During the process of the lifting plate driving the inclined ejector to move, the inclined surface and the inclined guide surface guide and cooperate, so that the inclined ejector can slide and compensate on the lifting plate in a direction perpendicular to the displacement of the lifting plate.

[0007] By adopting the above technical solution and setting a floating inclined ejector with an inclined surface guide structure, the single vertical ejection motion is transformed into a compound action of lateral micro-yield plus vertical ejection. This achieves flexible breaking of the initial clamping force of the product, effectively preventing problems such as whitening, puncture, or deformation of thin-walled or complex structure products during ejection, and improving product yield and the reliability of demolding action.

[0008] A further feature of this invention is that a mating block is fixedly provided on the lifting plate, and a sliding groove is provided on the mating block. A slider is fixedly provided at one end of the inclined top near the lifting plate, and the slider is slidably connected in the sliding groove so that the inclined top is slidably connected to the lifting plate.

[0009] By adopting the above technical solution, the sliding connection is achieved by using an independent mating block and slider combination. This not only makes the processing simpler and the precision easier to control, but also allows the mold precision to be restored simply by replacing the mating block or slider when the sliding pair wears out due to long-term use. This avoids the high cost and long downtime caused by replacing the entire lifting plate or inclined ejector, thus improving the maintainability and economy of the mold.

[0010] A further feature of this invention is that the lifting plate is provided with a limiting groove for accommodating the mating block, and the limiting groove and the sliding groove together define the sliding path of the slider.

[0011] By adopting the above technical solution, the mating block is positioned by setting a limiting groove on the lifting plate. On the one hand, this ensures that the installation position of the mating block will not shift under repeated ejection impacts, thus ensuring the accuracy and stability of the slider's sliding path. On the other hand, the side wall of the limiting groove directly bears and disperses the lateral force brought about by the slider's sliding, avoiding the loosening risk caused by relying solely on screws to bear shear force, and enhancing the overall rigidity and service life of the connection structure.

[0012] A further feature of this invention is that the inner wall of the core is formed with a first step extending toward the inclined top, and one end of the inclined top near the first step extends toward the core and forms a first limiting protrusion. During the mold closing process, the first limiting protrusion abuts against the first step and together constrains the displacement path of the inclined top.

[0013] By adopting the above technical solution, the first step and the first limiting protrusion that abut against each other provide a precise and rigid mechanical dead point for the reset position of the inclined ejector, ensuring that the position of the top surface of the inclined ejector is accurate after each mold closing, thereby ensuring the integrity of the cavity forming surface and the consistency of the bottom surface of the product; at the same time, this structure also shares the impact of injection pressure on the back slider of the inclined ejector, protecting the sliding connection structure.

[0014] A further feature of this invention is that the first insert forming mechanism includes a first forming insert movably disposed between the upper mold base and the core. The first forming insert has an installation cavity, and an elastic element is disposed in the installation cavity. One end of the elastic element abuts against the cavity wall of the installation cavity, and the other end abuts against the upper mold base. In the mold-closed state, the elastic element is in a pressurized and energy-storing state. When the lower mold assembly opens in a direction away from the upper mold base, the elastic element pushes the first forming insert to move away from the cavity.

[0015] By adopting the above technical solution, the built-in elastic element drives the first molding insert to be pulled away from the snap-fit ​​structure of the control panel mounting port at the moment of mold opening, realizing mechanical automatic release synchronized with the mold opening action. This effectively prevents the snap-fit ​​inside the control panel mounting port from being pulled, broken or deformed during subsequent overall ejection, ensuring the integrity of the assembly function of the control panel mounting port.

[0016] A further feature of this invention is that the elastic element is inclinedly disposed within the mounting cavity, with its inclination direction pointing away from the cavity.

[0017] By adopting the above technical solution, efficient force transmission is achieved, which can generate the maximum effective tripping stroke with a smaller spring force, avoiding energy waste caused by useless component force and frictional resistance between components, making the tripping action smoother and more stable.

[0018] A further feature of this invention is that a support column extending obliquely in the same direction as the elastic element is fixedly connected to the upper mold base, the support column extends into the mounting cavity, and the elastic element is sleeved on the support column.

[0019] By adopting the above technical solution, the support column, as the inner guide rod of the elastic element, constrains the axial trajectory of the elastic element during compression and extension, eliminating the problem of lateral bending or instability caused by excessive spring slenderness ratio or misaligned installation when under force, ensuring the stability of the elastic element during long-term operation and the consistency of the thrust direction, and extending the service life of the elastic element.

[0020] A further feature of this invention is that a hook is fixedly provided on the core, the hook portion of the hook extends toward the first molding insert, and a locking block corresponding to the position of the hook portion is provided on the first molding insert. When the mold is closed, the locking block is engaged in the recessed area of ​​the hook portion and forms an interlocking structure with the hook portion, so that the first molding insert is fixedly connected to the core.

[0021] By adopting the above technical solution, the forced mechanical engagement formed by the hook and the locking block can resist the pushing force of the high-pressure melt on the insert during mold closing, ensuring the accurate positioning of the first molded insert; after mold opening and release, it can also serve as a reliable rigid stroke limiter to accurately control the ejection distance of the insert, preventing it from being bounced off by the elastic element, and ensuring that the first molded insert can be accurately pressed back into position in the next mold closing cycle, thus forming a reliable self-locking and self-limiting mechanism.

[0022] A further feature of this invention is that the second insert forming mechanism includes a second forming insert, a driving cylinder, and a driving block fixedly connected to the lifting shaft of the driving cylinder. The second forming insert passes through the upper mold base. An inclined guide rail is provided on the driving block. One end of the second forming insert near the driving block is placed in the guide rail and guided and cooperated with it. The driving cylinder drives the second forming insert through the driving block, causing it to move in a direction close to or away from the core under the guidance of the guide rail.

[0023] By adopting the above technical solution, using an independent drive cylinder in conjunction with an inclined guide rail, the long-stroke, timing-controllable automated core pulling of the second forming insert is achieved, resulting in strong power and smoother operation.

[0024] A further feature of this invention is that the upper mold base is provided with a second step portion extending toward the direction of the second molding insert, and one end of the second molding insert near the second step portion extends toward the upper mold base and forms a second limiting protrusion. The second limiting protrusion abuts against the second step portion and together constrains the displacement path of the second molding insert when the mold is closed.

[0025] By adopting the above technical solution, a precise final insertion position limit is provided for the second molding insert, eliminating the slight position fluctuations caused by relying solely on cylinder stroke switches or hydraulic buffer positioning. This ensures that the insert end face is flush with other molding surfaces of the cavity during high-pressure injection molding, and that there are no parting line flash or step defects after the product is molded.

[0026] In summary, this utility model has the following beneficial effects: The upper mold base is equipped with a first insert forming mechanism for forming a first area of ​​the product and a second insert forming mechanism for forming a second area of ​​the product. The lower mold assembly is equipped with a product ejection mechanism. The lower mold assembly also includes a support base located below the lower mold base. A lifting plate that slides on the support base and moves linearly towards or away from the lower mold base is also present. The product ejection mechanism includes an inclined ejector. One end of the inclined ejector passes sequentially through the lower mold base and the core, forming part of the forming surface of the cavity. The other end is slidably connected to the lifting plate. An inclined surface is formed on the inclined ejector, and a surface is formed on the core that is inclined with respect to the inclined surface. The inclined guide surface corresponding to the inclined position guides the inclined ejector during the displacement of the inclined ejector driven by the lifting plate. The inclined surface and the inclined guide surface cooperate to enable the inclined ejector to slide and compensate on the lifting plate in a direction perpendicular to the displacement of the lifting plate. By setting a floating inclined ejector with an inclined guide structure, the single vertical ejection motion is transformed into a compound action of lateral micro-yield plus vertical ejection. This achieves flexible breaking of the initial clamping force of the product, effectively preventing the problems of ejection whitening, ejection penetration or deformation of thin-walled or complex structure products during ejection, and improving the product yield and the reliability of demolding action.

[0036] The present invention will be further described below with reference to the accompanying drawings.

[0037] A modular air fryer forming mold, such as Figure 1-8As shown, the system includes an upper mold base 1 and a lower mold assembly. The lower mold assembly includes a lower mold base 21 located below the upper mold base 1. A core 3 is provided on the lower mold base 21. The upper surface of the core 3 and the lower surface of the upper mold base 1 together form a precisely shaped cavity 13. The cavity 13 is used to inject molten plastic and cool it to form the final product. The upper mold base 1 is provided with a first insert forming mechanism and a second insert forming mechanism. The lower mold assembly is provided with a product ejection mechanism. The lower mold assembly also includes a support base 22 located below the lower mold base 21. A lifting plate 23 is slidably provided on the support base 22, which is linearly displaced (i.e., vertically displaced) in the direction of approaching or moving away from the lower mold base 21. The product ejection mechanism includes an inclined ejector 61. One end of the inclined ejector 61 passes through the lower mold base 21 and the core 3 in sequence, forming part of the forming surface of the cavity 13. The bottom surface of the product is directly formed on the end face of the inclined ejector 61. The other end of the top 61 is slidably connected to the lifting plate 23. The inclined top 61 has an inclined surface 611 formed on it, and the core 3 has an inclined guide surface 31 corresponding to the position of the inclined surface 611. When the product needs to be demolded after cooling and forming, the external power source (such as a hydraulic press) drives the lifting plate 23 to move vertically upward. At this time, since the bottom end of the inclined top 61 can slide on the lifting plate 23, the upward thrust and the guiding effect of the inclined surface 611 are linked: during the process of the inclined surface 611 sliding along the inclined guide surface 31, a horizontal component force will be generated on the inclined top 61, forcing the inclined top 61 to make a slight sliding compensation on the lifting plate 23 in a direction perpendicular to the displacement of the lifting plate 23. This compensation action can make the inclined top 61 produce a slight lateral retreat in the initial stage of ejection, thereby instantly breaking the vacuum adsorption and initial clamping force between the product and the core 3, and then continue to push the product out of the cavity 13 smoothly. By setting a floating inclined ejector 61 with an inclined surface 611 as a guide structure, the single vertical ejection motion is transformed into a compound action of lateral micro-yield plus vertical ejection. This achieves flexible breaking of the initial clamping force of the product, effectively preventing problems such as whitening, puncture, or deformation of thin-walled or complex structure products during ejection, and improving product yield and the reliability of demolding action.

[0038] Preferably, such as Figure 5-7As shown, a mating block 24 is fixedly installed on the lifting plate 23. The upper surface of the mating block 24 has an inwardly formed groove 241 with a "T"-shaped or dovetail-shaped cross-section. A slider 62 is fixedly installed at one end of the inclined top 61 near the lifting plate 23. The slider 62 is slidably connected within the groove 241, allowing the inclined top 61 to slide smoothly against the lifting plate 23. When the lifting plate 23 moves upward, the inclined surface 611 forces the inclined top 61 to perform lateral sliding compensation, and the slider 62 at the bottom of the inclined top 61 slides horizontally synchronously within the groove 241 of the mating block 24. Using an independent mating block 24 and slider 62 to achieve a sliding connection not only simplifies processing and makes precision easier to control, but also allows for easy restoration of mold precision when the sliding pair wears down due to long-term use. This avoids the high cost and prolonged downtime associated with replacing the entire lifting plate 23 or inclined top 61, improving the maintainability and economy of the mold.

[0039] Preferably, the lifting plate 23 has a limiting groove 231 for accommodating the mating block 24, and the depth is preferably one-third to one-half the thickness of the mating block 24. During installation, the mating block 24 is embedded into the limiting groove 231 and locked with screws. At this time, the side wall of the limiting groove 231, together with the bottom surface and side wall of the sliding groove 241, defines a closed or semi-closed precision sliding path, and the slider 62 is constrained to move within this path. By setting the limiting groove 231 on the lifting plate 23 to position the mating block 24, on the one hand, it ensures that the installation position of the mating block 24 will not shift under repeated ejection impacts, ensuring the accuracy and stability of the sliding path of the slider 62; on the other hand, the side wall of the limiting groove 231 directly bears and disperses the lateral force brought about by the sliding of the slider 62, avoiding the loosening risk caused by relying solely on screws to bear the shear force, and enhancing the overall rigidity and service life of the connection structure.

[0040] Preferably, the inner wall of the core 3 is formed with a first step portion 32 extending toward the inclined ejector 61. The end of the inclined ejector 61 near the first step portion 32 extends toward the core 3 and forms a first limiting protrusion 612. During the injection molding process when the mold is closed, the inclined ejector 61 is completely reset. At this time, the lower surface of the first limiting protrusion 612 on it will closely abut against the upper surface of the first step portion 32 of the core 3, forming a surface contact. Through the mutual abutment of the first step portion 32 and the first limiting protrusion 612, a precise hard mechanical dead point is provided for the reset position of the inclined ejector 61, ensuring that the position of the top surface of the inclined ejector 61 is accurate after each mold closing, thereby ensuring the integrity of the molding surface of the cavity 13 and the consistency of the bottom surface of the product; at the same time, this structure also shares the impact of the injection pressure on the back slider 62 of the inclined ejector 61, protecting the sliding connection structure.

[0041] Preferably, such as Figure 4As shown, the first insert forming mechanism includes a first forming insert 41 for forming the first area of ​​the product (the control panel mounting port of the air fryer). The first forming insert 41 is movably disposed between the upper mold base 1 and the core 3, and forms part of the forming surface of the cavity 13. A mounting cavity 411 is formed in the first forming insert 41, and an elastic element 42 is disposed in the mounting cavity 411. The elastic element 42 is preferably a spring. One end of the elastic element 42 abuts against the cavity wall of the mounting cavity 411, and the other end... The upper mold base 1 is abutted against; in the mold-closed state, the upper mold base 1 is pressed down, and the elastic element 42 is completely compressed between the cavity wall of the mounting cavity 411 and the upper mold base 1 to store energy; when the injection molding and cooling ends, when the lower mold assembly opens downward with the injection molding machine, the upper mold base 1 separates from the core 3, the external clamping force applied to the first molding insert 41 disappears, and the elastic element 42 immediately releases energy. Its elastic force pushes the first molding insert 41, causing it to generate a pre-displacement relative to the upper mold base 1 in a direction away from the cavity 13, thereby instantly separating it from the first area of ​​the product. By using the built-in elastic element 42 to drive the first molding insert 41 to first pull away from the snap-fit ​​structure of the control panel mounting port at the moment of mold opening, a mechanical automatic release synchronized with the mold opening action is realized, which effectively prevents the snap-fit ​​inside the control panel mounting port from being pulled, broken or deformed during subsequent overall ejection, ensuring the integrity of the assembly function of the control panel mounting port.

[0042] Preferably, the elastic element 42 is inclinedly disposed within the mounting cavity 411, with its inclination direction pointing away from the cavity 13, i.e., pointing towards the demolding direction in which the snap fastener at the control panel mounting opening needs to be withdrawn. When the elastic element 42 extends, the thrust it applies to the first molding insert 41 is an oblique force along this inclination direction. This force can be decomposed into a horizontal main component force that moves the first molding insert 41 away from the cavity 13, and an auxiliary vertical component force, achieving efficient force transmission. This allows for the generation of the maximum effective release stroke with a smaller spring force, avoiding energy waste caused by useless component forces and frictional resistance between components, making the release action smoother and more stable.

[0043] Preferably, a support column 11 extending obliquely in the same direction as the elastic element 42 is fixedly connected to the upper mold base 1 via threads. The support column 11 extends into the mounting cavity 411, and the elastic element 42 is sleeved on the support column 11. The support column 11 serves as an inner guide rod for the elastic element 42, constraining the axial trajectory of the elastic element 42 during compression and extension. This prevents lateral bending or instability caused by excessive spring slenderness ratio or misaligned installation under stress, ensuring the stability of the elastic element 42 during long-term operation and the consistency of the thrust direction, thus extending the service life of the elastic element 42.

[0044] Preferably, an "L"-shaped hook 33 is fixedly installed on the core 3 by screws. The hook extends upward and faces the first molding insert 41. The first molding insert 41 is provided with a locking block 43 corresponding to the position of the hook. When the mold is closed, the locking block 43 engages with the recessed area of ​​the hook and forms an interlocking structure with the hook, so that the first molding insert 41 is fixedly connected to the core 3. The forced mechanical interlocking formed by the hook 33 and the locking block 43 can resist the pushing force of the high-pressure melt on the insert when the mold is closed, ensuring the accurate positioning of the first molding insert 41. After the mold is opened and released, it can also serve as a reliable rigid stroke limiter, accurately controlling the release distance of the insert and preventing it from being bounced off by the elastic element 42. This ensures that the first molding insert 41 can be accurately pressed back into position in the next mold closing cycle, forming a reliable self-locking and self-limiting mechanism.

[0045] Preferably, the second insert forming mechanism includes a second forming insert 51 for forming the second area of ​​the product (the air vent of the air fryer), a drive cylinder 52, and a drive block 53 fixedly connected to the lifting shaft of the drive cylinder 52. The second forming insert 51 forms part of the forming surface of the cavity 13. The drive block 53 has an inclined guide rail 531 with a "T" or dovetail cross-section. The tail end of the second forming insert 51 is a slider 62 structure that matches the contour of the guide rail 531 and is assembled in the inclined guide rail 531 to form a guiding fit. The lifting shaft (piston rod) of the drive cylinder 52 does not directly push or pull the insert, but converts the vertical movement through the drive block 53 into the inclined extraction or insertion movement of the second forming insert 51 via the inclined guide rail 531. By using an independent drive cylinder 52 in conjunction with the inclined guide rail 531, the long-stroke, time-controllable automated core pulling of the second forming insert 51 is achieved, which is powerful and the operation is more stable.

[0046] Preferably, the upper mold base 1 is provided with a second stepped portion 12 extending toward the second molding insert 51. On the upper surface of the tail of the second molding insert 51 (the end near the drive block 53), a second limiting protrusion 511 is formed upward. When the drive cylinder 52 pushes the second molding insert 51 to reset and insert into the cavity 13 through the drive block 53, the upper surface of the second limiting protrusion 511 of the second molding insert 51 will eventually abut tightly against the lower surface of the second stepped portion 12 of the upper mold base 1, forming a rigid contact dead point. Through the above structural design, a precise final insertion position limit is provided for the second molding insert 51, eliminating the slight position fluctuations caused by relying solely on cylinder stroke switches or hydraulic buffer positioning, ensuring that the insert end face is flush with other molding surfaces of the cavity 13 during high-pressure injection molding, and that there are no parting line flash or step defects after product molding.

[0047] The above description is only a preferred embodiment of the present utility model.
