Description

Technical Field

[0001] The present invention relates to the technical field of molds, in particular to pressure processing equipment. Background Art

[0002] With the development of the manufacturing industry, the requirements for product component assembly are becoming increasingly stringent. The demand for product quality and shipment volume is also increasing. To meet the process requirements for laminating flexible, stretchable, and elastic materials to relatively rigid shell parts, the flexible, stretchable, and elastic materials must be stretched and laminated. The resulting finished parts must have uniform color. For example, for fabric, the warp and weft must be uniform, preventing the base color of the shell from showing through. For leather, the thickness must be uniform. Existing processing methods still have these drawbacks, resulting in low yield rates. Therefore, the processing methods for laminating flexible, stretchable, and elastic materials to relatively rigid shell parts continue to require continuous optimization and improvement.

[0057] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0058] It should be noted that if a directional indication is involved in an embodiment of the present invention, the directional indication is only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture.

Therefore, the features specified as "first" and "second" may explicitly or implicitly include at least one of such features.

When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0060] With the development of the manufacturing industry, the requirements for product component assembly are becoming increasingly stringent. The demand for product quality and shipment volume is also increasing. To meet the process requirements for laminating flexible, stretchable, and elastic materials to relatively rigid shell parts, the flexible, stretchable, and elastic materials must be stretched and laminated. The resulting finished parts must have uniform color. For example, for fabric, the warp and weft must be uniform, preventing the base color of the shell from showing through. For leather, the thickness must be uniform. Existing processing methods still have these drawbacks, resulting in low yield rates. Therefore, the processing methods for laminating flexible, stretchable, and elastic materials to relatively rigid shell parts continue to require continuous optimization and improvement.

[0061] In view of this, the present invention provides a pressure processing equipment, which first makes the elongation of the flexible material close to the final stretched shape, and then bonds the material to multiple parts of the shell parts, avoiding the defect of uneven stretching color caused by single local stretching. At the same time, it realizes the combination of multiple scattered processes, reduces the number of workstations, and saves manpower and space. Figures 1 to 8 This is an embodiment of the pressure processing equipment provided by the present invention.

[0062] It should be noted that the present invention does not limit the specific material of the flexible material, which can be a flexible and ductile material such as microfiber cloth, leather, etc. The open upper end of the shell part refers to the shape of the shell when it swings on the circulation tooling. Its orientation during actual use is not limited, and the specific material of the shell part is not limited. The pressure processing equipment is a pressure mold, which can be a cold pressing mold or a hot pressing mold, and is not limited here.

[0063] Specifically, the effect of the relevant structure is described below by taking the example of laminating a flexible fabric on a mobile phone case with a curved surface through a hot pressing mold.

[0064] Please refer to Figures 1 to 3 The pressure processing equipment 100 includes a lower die group 1 and an upper die group 2, the lower die group 1 is used for placing the circulation tooling with the assembly to be processed, the upper die group 2 is arranged above the lower die group 1, the upper die group 2 and the lower die group 1 can move relative to each other in the up and down directions, the upper die group 2 includes a pressing structure 21, the pressing structure 21 can stretch the flexible material in the assembly to be processed during the relative movement of the upper die group 2 and the lower die group 1, and make the flexible material in the assembly to be processed fit with the shell part with an open upper end when the upper die group 2 and the lower die group 1 are closed.

[0065] In the technical solution of the present invention, during the process of the upper mold group 2 and the lower mold group 1 approaching each other, the pressing structure 21 stretches the flexible material as a whole, first making the elongation of the flexible material close to the final stretched shape, and through reasonable design of the structure, or control of the distance between the upper mold group 2 and the lower mold group 1, during this period, the flexible material on the circulation tooling is stretched, but does not fit with the shell parts. Only when the upper mold group 2 and the lower mold group 1 move to the mold closing stage, the flexible material in the assembly to be processed and the shell parts with the upper end open are fit together, thereby relying on the pressure processing equipment 100 to complete the lamination of the flexible material with the bottom surface, peripheral side wall and curved surface section of the shell parts at only one workstation, thereby ensuring the uniform color of the flexible material after stretching and improving the yield rate. At the same time, there is no need to separately design multiple scattered processes to complete multiple stretching and laminating actions, which reduces the number of workstations, saves manpower and space, and takes shorter processing time.

[0066] It is understandable that the flexible material may need to cover the entire inner surface of the shell part, or may only cover a part of the inner surface of the shell part. The pressing structure 21 can be designed according to actual processing requirements. In this embodiment, the entire inner surface of the shell part is covered. Considering the shape of the shell part, please refer to Figures 2 to 4 The pressing structure 21 includes a pressing block 211 and a plurality of sliding parts 212. The pressing block 211 can move in the up and down directions. The lower end surface of the pressing block 211 is used to correspond to the bottom surface of the shell part. The plurality of sliding parts 212 are arranged in sequence along the circumference of the pressing block 211. The plurality of sliding parts 212 can move in the up and down directions, and the plurality of sliding parts 212 have a movable stroke close to or away from the pressing block 211. The shape of the plurality of sliding parts 212 is used to adapt to the shell part to correspond to the peripheral side wall of the shell part and the curved surface segment between the peripheral side wall and the bottom surface. The pressing block 211 and the plurality of sliding parts 212 can both move in the up and down directions, and the plurality of sliding parts 212 can also move linearly relative to the pressing block 211. The plurality of sliding parts 212 are contoured, corresponding to the peripheral side walls and curved sections of the shell parts, and their main function is to stretch and coat the side of the flexible material. The lower end surface of the pressing block 211 remains flat, and its main function is to stretch and coat the middle of the flexible material. During the mold closing process, as the upper mold group 2 falls, the pressing block 211 and the The multiple sliding parts 212 first move downward together and then come into contact with the flexible material. At this time, the multiple sliding parts 212 move in a direction away from the pressure block 211. The pressure block 211 can continue to move downward or maintain its height. As the upper mold assembly 2 continues to fall, since each sliding part 212 moves relative to the pressure block 211 and moves up and down, the entire mold assembly moves diagonally from top to bottom away from the center. The pressure block 211 continues to move downward, thereby driving the stretched flexible material to fit the shell parts accordingly during mold closing. The mold is closed for a period of time and then opened. During the mold opening process, the sliding parts 212 should move in a direction close to the pressure block 211 to reset.

[0067] The present invention does not limit the driving method of the movement of the sliding part 212 relative to the pressing block 211. In one embodiment, the upper mold assembly 2 also includes a driving part 22, and the driving part 22 can move in the upper and lower directions. The driving part 22 is located between the multiple sliding parts 212, and the lower end face of the driving part 22 is connected to the pressing block 211. The peripheral side surfaces of the lower end of the driving part 22 are all inclined from top to bottom toward the center of the driving part 22. The sides of the multiple sliding parts 212 facing the driving part 22 are all mating surfaces, and each mating surface is inclined with respect to the driving part 22. The synchronous driving of multiple sliding parts 212 by one driving part 22 is achieved by the bevel mating method, maintaining good consistency. Taking into account the size of the sliding part 212 and the coordination with other components, the size of the inclined surface around the driving part 22 can be reasonably designed.

[0068] Furthermore, on the side surfaces of each sliding portion 212 opposite to the driving portion 22, one is provided with a slide groove 2121, and the other is provided with a slide rail 221, and the slide rail 221 is slidably engaged with the slide groove 2121. The engagement of the slide rail 221 and the slide groove 2121 provides a good connection effect and movable guidance for the sliding portion 212 and the driving portion 22. The slide rail 221 and the slide groove 2121 are preferably designed to be special-shaped, for example, the slide groove 2121 is designed to be a T-slot, a dovetail groove, etc. It is understood that good engagement precision should be maintained to ensure the effect of the sliding engagement.

[0069] It should be noted that the pressing block 211 and each sliding part 212 can also cooperate with each other through the sliding groove 2121 and the sliding rail 221. However, since the pressing block 211 itself does not play a driving role on each sliding part 212, the pressing block 211 and each sliding part 212 should maintain a sufficient gap to avoid interference.

[0070] The present invention does not limit the specific number of the multiple sliding portions 212, and they can be reasonably arranged according to the size and shape of the housing component. In this embodiment, eight sliding portions 212 are provided, and the multiple sliding portions 212 include two first sliding portions opposing each other in the transverse direction, two second sliding portions opposing each other in the longitudinal direction, and a third sliding portion located between each adjacent first and second sliding portion. In this case, the four third sliding portions correspond to the four corners of the housing component, and the first and second sliding portions correspond to the long and short sides of the housing component, respectively. In one embodiment, the side surfaces of the third sliding portions that mate with the corresponding first and second sliding portions are inclined. Specifically, the angle between the side surfaces and the corresponding straight edges is 30°, which facilitates non-interference between the sliding portions when mating and separating. In another embodiment, the extending direction of the mating surface of the third sliding portion intersects the extending direction of the mating surface of the corresponding first and second sliding portions, that is, the pressing block 211 is correspondingly arranged in an octagonal shape. In this embodiment, the above two features are provided simultaneously to ensure the mating effect of the multiple sliding portions 212 and the sliding opening effect.

[0071] It can be understood that the inclination angles of the inclined surfaces formed by the cooperation of the multiple sliding parts 212 and the driving part 22 can be the same or different. In this embodiment, the angle between the inclined surfaces of the first slider and the second slider and the driving part 22 and the vertical plane is 6°, and the angle between the inclined surfaces of the third slider and the driving part 22 and the vertical plane is 20°.

[0072] To ensure that each of the sliding portions 212 can automatically reset when the mold is opened, in one embodiment, a first annular mounting frame 23 is further provided on the exterior of the plurality of sliding portions 212. The inner hole of the first mounting frame 23 is for the pressure block 211 to movably pass through, and the first mounting frame 23 is for mounting the plurality of sliding portions 212. The upper mold assembly 2 also includes a reset structure, which includes a plurality of elastic members 24 arranged corresponding to the plurality of sliding portions 212. One end of each elastic member 24 abuts against the corresponding sliding portion 212, and the other end abuts against the first mounting frame 23. The present invention is not limited to the specific form of the elastic member 24. It can be a single spring, a spring and a guide rod, or a spring. Specifically, in its natural state, each of the elastic members 24 is in a pre-compressed state. When the plurality of sliding portions 212 move away from each other, the elastic member 24 is compressed. When the mold is opened, the plurality of sliding portions 212 can be reset due to the rebound force. In other embodiments, other pushing structures can be added to push the sliding portions 212 in the opposite direction to achieve reset. This is not limited here.

[0073] In other embodiments, to drive the multiple sliding portions 212, the upper die assembly 2 further includes an auxiliary drive unit 22. The auxiliary drive unit 22 includes a plurality of rods 25 that can move in the vertical direction. The rods 25 are spaced apart along the circumference of the pressure block 211 and, corresponding to the multiple sliding portions 212, the lower end of each rod 25 is tilted from top to bottom toward the center of the pressure block 211. Each sliding portion 212 has an inclined hole corresponding to each rod 25 for the corresponding rod 25 to pass through. Each sliding portion 212 can move toward or away from the pressure block 211 during the movement of each rod 25. The number of rods 25 can be matched according to the size of each sliding portion 212. One sliding portion 212 corresponds to one or more rods 25. Through the oblique insertion, the sliding portion 212 can be directly driven to reciprocate. It is understood that the auxiliary drive unit 22 can be designed separately or provided simultaneously with the drive unit 22 to provide a double insurance and a guiding effect.

[0074] In order to prevent the mold structure from scratching the material during the stretching and laminating process, a protective pad is generally installed between the material and the mold structure. Considering the pressure caused by the cavity during mold closing, it may affect the ductile and deformable protective pad and the flexible material, thereby forming air bulges, causing the local area to fit with the shell parts in advance. The fitted part cannot continue to stretch, and the warp and weft of the corresponding fabric are fixed, resulting in poor uniformity after laminating. Therefore, the lower end face of the pressing block 211 is provided with a plurality of exhaust holes 2111, each of which can be connected to the external environment. The present invention does not limit the number and arrangement of the exhaust holes 2111. It can be connected to the outside by processing exhaust grooves, connecting county holes, etc., so as to balance the air pressure.

[0075] Furthermore, the pressing block 211 is detachably connected to the driving unit 22. Considering that the device may be affected by temperature or pressure during hot and cold pressing, the pressing block 211 and the driving unit 22 may still be connected even if the connecting screws are removed in time, and the pressing block 211 is not easy to remove. Therefore, please refer to Figure 6At least one first through-hole 2122 is formed on the side of at least one sliding portion 212, and a second through-hole 222 is formed on the driving portion 22 corresponding to the first through-hole 2122. A slot 2112 is formed on the upper end of the pressing block 211 corresponding to the second through-hole 222. The upper end of the slot 2112 is open, and the bottom wall is inclined from top to bottom toward the second through-hole 222. The side wall of the slot 2112 is connected to the second through-hole 222, so that the external disassembly part 200 can pass through the first through-hole 2122 and the second through-hole 222 in sequence and extend into the slot 2112, and the end of the external disassembly part 200 is in contact with the bottom wall of the slot 2112. The disassembly part 200 is a rod-shaped structure, and the end portion is adapted to the shape of the slot 2112, and the overall structure is a wedge-shaped structure. After the finished part is taken out, the position of the sliding part 212 is adjusted so that the first through hole 2122 and the second through hole 222 are correspondingly connected. The operator manually inserts the disassembly part 200 into the slot 2112 and removes the pressure block 211 with the help of external force. The first through hole 2122, the second through hole 222 and the slot 2112 can also be used for exhaust to balance the air pressure, and can also be used as a positive and negative reference for the operator when assembling the module.

[0076] In order to realize the gradual stretching and covering action of the flexible fabric during the falling process of the upper mold assembly 2, please refer to 7 to Figure 8The lower die 1 includes a second mounting base 11 and a plurality of movable parts 12. The upper surface of the second mounting base 11 is provided with a plurality of grooves 111. Each movable part 12 is movably mounted in the groove 111 and has a raised position protruding from the groove 111 and an avoidance position in the groove 111. When the movable part 12 is in the raised position, the pressing structure 21 contacts the flexible material in the assembly to be processed, and the flexible material is spaced apart from the shell part. When the movable part 12 is in the avoidance position, the pressing structure 21 makes the flexible material in the assembly to be processed fit the shell part. Due to the cushioning effect of the movable part 12, the height of the pressing structure 21 is always limited, thereby ensuring that the flexible material does not fit the shell parts and can be stretched first. When the resistance is overcome and the movable part 12 is driven to be transformed into the avoidance position, the pressing structure 21 can drive the flexible material to fit. In the specific mechanism, when the upper mold group 2 includes a first mounting base 26 and a first mounting frame 23, the middle part of the lower end surface of the first mounting base 26 is provided for the installation of the pressing block 211; the first mounting frame 23 is located below the first mounting base 26 and can be elastically installed on the first mounting base 26, and is arranged in a ring shape for the pressing block 211 to be movable through, and the first mounting frame 23 is provided for the installation of the multiple sliding parts 212; the first mounting frame 23 can be installed through horizontal and vertical positioning holes, guide sliders, hanging cooperation, etc., and is not limited here. As the upper mold assembly 2 continues to fall, at the beginning, the first mounting frame 23 and the first mounting base 26 fall together, that is, the pressing block 211 and the sliding portion 212 fall synchronously, and as a part of the upper mold assembly 2 contacts the movable portion 12, the first stage of synchronous falling is completed. Then the upper mold assembly 2 continues to fall and needs to overcome the resistance of the movable portion 12. Due to the elastic connection between the first mounting frame 23 and the first mounting base 26, the corresponding elastic mounting structure is compressed first during the continued falling process of the upper mold assembly 2. At this time, the position of the pressing block 211 is fixed, and the multiple sliding portions 212 move horizontally away from the pressing block 211. When the elastic mounting structure The structure is compressed until the force exerted by the upper mold group 2 and the resistance of the movable part 12 are balanced, completing the second stage. During this process, due to the padding effect of the movable part 12, the height of the pressing block 211 and the sliding part 212 is always limited, thereby ensuring that the flexible material does not fit with the shell parts and always maintains a distance. When the upper mold group 2 continues to fall, the movable part 12 is squeezed from the padding position to the avoidance position. During this process, the pressing block 211 moves downward as a whole, and the sliding part 212 moves obliquely. When the movable part 12 is completely received in the groove 111, the upper mold group 2 and the lower mold group 1 are clamped to make the flexible material in the assembly to be processed fit with the shell parts, completing the entire process.

[0077] The present invention does not limit the specific method of elastic connection. In one embodiment, the first mounting frame 23 and the first mounting base 26 are elastically connected by multiple rectangular springs 27. The upper end and lower end of each rectangular spring 27 are partially embedded in the first mounting base 26 and the first mounting frame 23 respectively. In order to improve the guiding effect, equal height screws or limiting guide columns can be added for cooperation.

[0078] To provide sufficient resistance, multiple disc springs 13 are positioned between each movable portion 12 and the bottom wall of the corresponding recess 111. In this embodiment, the disc springs 13 are arranged in series, meaning that adjacent disc springs 13 have corresponding inner or outer diameters. These disc springs 13 provide significant resistance while maintaining minimal compression, enabling better adaptation. Other structural forms may also be employed in other embodiments, and are not intended to be limiting.

[0079] In this embodiment, the upper die assembly 2 is elastically mounted by rectangular springs 27 , and the lower die assembly 1 provides resistance by disc springs 13 . The number of rectangular springs 27 corresponds to the number of disc springs 13 .

[0080] To limit the height of the movable portion 12 protruding from the lower die assembly 1 in its natural state, in this embodiment, the lower die assembly 1 further includes a plurality of stoppers 14 corresponding to the plurality of movable portions 12. Each stopper 14 passes through the inner hole of the corresponding movable portion 12 and the plurality of disc springs 13 and is connected to the bottom wall of the recess 111. The stopper 14 can be a screw or other part, functioning as a height-conforming screw, limiting the height of the movable portion 12 while pre-compressing the disc springs 13.

[0081] It should be noted that by designing the specifications and preload of the disc spring 13, different bonding sequences can be achieved when the flexible material is bonded, corresponding to meeting various process requirements of simultaneous or sequential bonding with the bottom surface and side wall of the shell part.

[0082] Based on the design of the active part 12, please refer to Figure 3 and Figure 5The upper mold assembly 2 further includes a plurality of first stoppers 28 circumferentially mounted along the first mounting frame 23 . Each first stopper 28 is positioned corresponding to each movable portion 12 and protrudes horizontally from the movable portion 12 to contact the movable portion 12 when the movable portion 12 is in the elevated position, and to contact the first mounting base 26 when the movable portion 12 is in the avoidance position. The plurality of first stoppers 28 serve as position limiters. Considering the position of the movable portion 12, the design of the first stoppers 28 not only incorporates the design of localized thermal insulation materials but also sizing to ensure that the movable portion 12 can be positioned relative to its end face when in the elevated position. As the upper mold assembly 2 descends to overcome resistance, the first stoppers 28 are able to cross over the movable portion 12 and the groove 111 to contact the corresponding end face of the lower mold assembly 1, thereby providing a position limiter and preventing the movable portion 12 from being affected by the rise and fall of the movable portion 12.

[0083] It can be understood that, under the joint action of the first limit block 28 and the movable portion 12 , the first limit block 28 plays a role of hard limit, and the movable portion 12 plays a role of soft limit.

[0084] In addition, the upper mold assembly 2 includes a connecting seat 29 and a first mounting base 26. The first mounting base 26 is positioned below the connecting seat 29 and can deflect laterally and longitudinally relative to the connecting seat 29. The first mounting base 26 provides a partial mounting position for the press-fit structure 21. This allows for a certain degree of flexibility and adaptability for the first mounting base 26, enabling in-plane deflection to ensure mold clamping accuracy. Specifically, in this embodiment, floating deflection is achieved by adding multiple conventional screws that cooperate with the contour sleeves 5. Each contour sleeve 5 has a first stepped surface on its outer surface facing the connecting seat 29. A first floating gap is defined between the first stepped surface and the first mounting base 26, while a second floating gap is defined between the outer circumference of the contour sleeve 5 and the corresponding hole. This configuration is simple and space-saving. By defining the dimensions of the first and second floating gaps, the degree of floating motion is controlled, achieving accurate positioning. When the press-fitting apparatus 100 is a hot press, the connecting seat 29 can be made of a heat-insulating material to provide insulation and reduce heat loss.

[0085] In addition, the various parts of the mold structure are connected by multiple equal-height screws to ensure the connection strength and the limitation of height position.

[0086] Please refer again Figure 1The pressure processing equipment 100 also includes at least one lateral positioning structure, and the lateral positioning structure includes a first matching block 31 and a first positioning block 32. The first matching block 31 is fixed to the side of the upper mold group 2, and the lower end surface of the first matching block 31 is concavely formed with a first groove. The first positioning block 32 is fixed to the side of the lower mold group 1, and the upper end of the first positioning block 32 is convexly formed to form a first protrusion. The side surface of the first protrusion is tightly fitted with the side wall surface of the first groove. Specifically, the end of the first protrusion and the bottom wall surface of the first groove do not contact each other, and there is a certain gap between the two. The lateral positioning structure mainly relies on the cooperation of the side for guidance, that is, the cavity of the upper mold group 2 and the lower mold group 1 is completely buckled. It is not easy to be padded due to external positioning, and it does not affect the hot pressing process while ensuring guidance. Specifically, four lateral positioning structures are provided in this embodiment. This is because the mold is generally provided in a square shape, corresponding to four circumferential sides.

[0087] Furthermore, the upper mold assembly 2 is provided with a connecting seat 29, a first mounting base 26, a first mounting frame 23 and other structures. The first matching block 31 is fixed on the first mounting frame 23, and its upper part extends up and down, and can pass through the connection and the first mounting base 26 to simultaneously play a role in positioning and guiding.

[0088] To ensure that the assembled circulation fixture is properly positioned and aligned with the lower module 1, in one embodiment, the upper surface of the lower module 1 is provided with multiple positioning pins 15 for engaging with positioning holes on the circulation fixture. These multiple positioning pins 15 provide horizontal and vertical positioning limits to prevent the circulation fixture from swaying. In other embodiments, the upper surface of the lower module 1 is further provided with at least one proximity switch 16 for detecting the position of the circulation fixture. This allows for determining whether the current circulation fixture is aligned and confirming whether the circulation fixture is present on the lower module 1. In this embodiment, both positioning pins 15 and proximity switches 16 are provided.

[0089] Considering the structure of the shell parts, the adhesive is usually applied on the flexible material for lamination. In order to ensure a good bonding effect, the adhesive is usually activated by hot pressing. For details, please refer to Figure 4 The pressure processing equipment 100 also includes a plurality of heating structures 4, and the plurality of heating structures 4 are arranged around the pressing structure 21. Each of the heating structures 4 includes an electrically connected heating rod and a temperature control device to locally heat the pressing structure 21. When the temperature does not meet the processing conditions, the heating rod is controlled to continue heating. When the temperature meets the requirements, the heating rod is controlled to stop heating. Specifically, two heating rods are arranged on each sliding part 212, and each heating rod corresponds to a temperature sensing line as a temperature control device.
