Description

Technical Field

[0001] This utility model relates to the field of fabric three-dimensional hot pressing technology, and more specifically, to a fabric three-dimensional hot pressing molding device. Background Technology

[0002] Plastic artificial flowers are widely used in home decoration and commercial layout due to their advantages of being beautiful, durable, and requiring no maintenance. The three-dimensional shape of their flexible parts, such as petals and sepals, directly determines the product's realism and market competitiveness. Therefore, hot pressing molding process is required to form regular three-dimensional structures to restore the form and texture of natural flowers and meet consumers' demand for highly realistic products.

[0003] Currently, the hot pressing equipment used in the industry requires operators to be close to the hot pressing mold working area to complete both material loading and unloading operations, making it impossible to complete the entire operation from a safe workstation far away from the equipment.

[0004] However, in actual production and operation, this type of equipment has certain problems: on the one hand, operators need to work close to the mold area, making it impossible to safely load and unload materials from a distance, resulting in poor operational convenience and safety risks; on the other hand, the mold positioning accuracy is insufficient during the hot pressing process, which easily leads to positional deviations, resulting in deviations in the molding size of the simulated flower parts and poor consistency in shape, directly affecting the product's simulation degree and production qualification rate. Therefore, we urgently need a fabric three-dimensional hot pressing molding device to solve the above problems. Utility Model Content

[0005] One objective of this invention is to provide a new technical solution for a fabric three-dimensional hot pressing molding device. Through the automatic switching of dual-station molds and the collaboration of multiple precise positioning structures, it enables operators to safely load and unload materials away from the hot pressing danger zone, while taking into account both production continuity and molding accuracy. It is suitable for the efficient production of various styles of plastic simulated flowers.

[0006] According to a first aspect of the present invention, a three-dimensional hot pressing molding device for fabric is provided, including a machine base and a mounting frame slidably connected to the machine base support, and further including: an upper mold fixedly mounted on the mounting frame, a lower mold matching the upper mold being provided on the machine base, wherein when the upper mold and the lower mold are coaxial, the mounting frame and the upper mold move downward and form a hot pressing zone with the lower mold; a driving component provided on the machine base for switching the lower mold, and a support platform for supporting the lower mold being fixedly mounted on the machine base, wherein when the lower mold abuts against the support platform, it is fixed by a positioning component;

[0007] The positioning component includes an opening groove (17) on the support platform (5) adapted to the first magnetic suction plate (15). An anti-slip pad (18) for abutting is fixedly installed on the inner wall of the closed side of the opening groove (17). A second magnetic suction plate (19) attracted to the first magnetic suction plate (15) is fixedly installed on the bottom wall of the opening groove (17). When the first magnetic suction plate (15) and the second magnetic suction plate (19) are magnetically attracted, the mounting base (14) and the anti-slip pad (18) abut against each other to form a positioning area. The support platform (5) is symmetrically provided with sliding grooves (20) adapted to the guide block (16). When in the positioning area, the guide block (16) is located in the sliding groove (20) and abuts against its inner wall.

[0008] The support platform (5) has a rectangular through hole (21). Slide rails (22) for sliding are symmetrically installed in the rectangular through hole (21). A lever (23) is provided in the rectangular through hole (21). The lever (23) is connected to the slider (24) in the corresponding slide rail (22). A spring (25) is provided in the slide rail (22). The two ends of the spring (25) are connected to the slider (24) and the inner wall of the slide rail (22) respectively. A push rod (26) adapted to the lever (23) is fixedly installed on the mounting base (14). When in the positioning area, the push rod (26) abuts against the lever (23) and forms a pushing area.

[0009] A third magnetic plate (27) is fixedly installed on the lever (23) via a frame, and a fourth magnetic plate (28) that attracts the third magnetic plate (27) is fixedly installed on the push rod (26) via a frame. When in the push zone, the third magnetic plate (27) and the fourth magnetic plate (28) are magnetically attracted.

[0010] A snap-fit ​​plate (29) is rotatably connected to the machine base (1) via a return spring on the upright. The snap-fit ​​plate (29) consists of a snap-fit ​​section and a moving section. A positioning plate (30) adapted to the snap-fit ​​plate (29) is fixedly installed on the mounting base (14). When in the pushing zone, the moving rod (23) contacts the moving section, and the snap-fit ​​section snaps onto the positioning plate (30) to form a limiting zone. When the moving rod (23) disengages from the moving section, the snap-fit ​​section disengages from the positioning plate (30).

[0011] Optionally, a hydraulic cylinder for driving the mounting frame is fixedly installed on the bracket. The output end of the hydraulic cylinder is fixedly installed on the mounting frame. A heater connected to an external control unit is fixedly installed on the mounting frame for heating the upper mold. When the hydraulic cylinder drives the mounting frame to work, the upper mold moves along the guide rod on the bracket.

[0012] Optionally, the driving component includes electric guide rails symmetrically mounted on the machine base. A horizontal plate is provided on the machine base, and the horizontal plate is connected to the output ends of the two sets of electric guide rails for adjusting the position of the horizontal plate. A drive motor is fixedly mounted on the horizontal plate, and the drive motor is located in a sliding groove opened on the machine base. A rotating disk is rotatably connected to the horizontal plate, and the output end of the drive motor is connected to the rotating disk for driving the rotating disk to rotate.

[0013] Optionally, a rectangular box is fixedly installed on the rotating disk, and electric push rods are symmetrically installed on the rectangular box. The output ends of the two sets of electric push rods are fixedly installed with mounting bases for driving the mounting bases to move. The lower mold is threadedly connected to the mounting base. A first magnetic suction plate is fixedly installed at the bottom of the mounting base. Guide blocks are integrally formed at the bottom of the mounting base and on both sides of the first magnetic suction plate.

[0014] 1. According to one embodiment of this disclosure, the fabric three-dimensional hot pressing molding device uses an electric guide rail and a drive motor to drive a rotating disk to achieve automatic switching of two sets of lower molds. With the help of an electric push rod to drive the mounting base to move precisely, one set of molds can be processed in the hot pressing work area while the other set of molds can be loaded and unloaded in a safe work station away from the high temperature and high pressure danger area. This not only effectively avoids the safety hazards caused by operators approaching the hot pressing area, but also realizes the parallel operation of processing and loading and unloading processes, greatly shortens the production cycle, and significantly improves the mass production efficiency of plastic artificial flowers. At the same time, the threaded connection design between the lower mold and the mounting base facilitates the quick replacement of different mold shapes, adapting to the customized production needs of various styles of artificial flowers.

[0015] 2. According to one embodiment of this disclosure, the fabric three-dimensional hot pressing molding device forms a multi-coordinated positioning structure through the guiding cooperation of the guide block and the slide groove, the magnetic positioning of the first magnetic plate and the second magnetic plate, the pressing and limiting of the anti-slip pad, and the magnetic linkage of the push rod and the toggle rod triggering the locking of the snap-fit ​​plate and the positioning plate. This effectively ensures the precise coaxiality of the lower mold and the upper mold when they are closed, effectively preventing problems such as product shape deformation and dimensional deviation caused by mold offset and loosening during the hot pressing process. This significantly improves the molding accuracy and product consistency of the plastic simulated flower parts. At the same time, the cooperation design of the slide rail and the spring realizes the automatic reset and unlocking of the positioning structure without manual intervention, further improving the automation and stability of the equipment operation and reducing the scrap rate and labor intensity.

[0025] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present invention.

[0026] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the invention or its application or use.

[0027] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0028] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0029] like Figures 1-6 As shown, a three-dimensional fabric thermoforming device includes a machine base 1 and a mounting frame 2 slidably connected to a support of the machine base 1.

[0030] It also includes an upper mold 3 fixedly installed on the mounting frame 2, a lower mold 4 matching the upper mold 3 on the machine base 1, a hydraulic cylinder 6 for driving the mounting frame 2 fixedly installed on the bracket, the output end of the hydraulic cylinder 6 fixedly installed on the mounting frame 2, a heater 7 connected to an external control unit fixedly installed on the mounting frame 2 for heating the upper mold 3. When the hydraulic cylinder 6 drives the mounting frame 2 to work, the upper mold 3 moves along the guide rod on the bracket. When the upper mold 3 and the lower mold 4 are coaxial, the mounting frame 2 and the upper mold 3 move down and form a hot pressing zone with the lower mold 4.

[0031] Here, the hydraulic cylinder 6 adopts a direct drive to drive the mounting bracket 2 to move directionally along the guide rod, which can ensure that the upper mold 3 runs stably without wobbling. The heater 7 is uniformly regulated by an external control unit, which can adapt to the hot pressing temperature requirements of plastic simulated flower sheets, and avoid the raw material being burned by excessively high temperature or the molding effect being poor due to excessively low temperature.

[0032] Furthermore, the upper mold 3 and the lower mold 4 are aligned coaxially before being closed to form a hot pressing zone, which can prevent mold misalignment from the source and ensure that the petals, leaves and other parts of the plastic artificial flowers are subjected to uniform force, effectively improving the consistency and realism of the three-dimensional shape.

[0033] Furthermore, the guide rod limits the movement path of the upper mold 3, and in conjunction with the stable output of the hydraulic cylinder 6, it can not only ensure constant hot pressing pressure, but also reduce equipment vibration, extend the service life of the mold, and reduce the molding scrap rate.

[0034] A drive unit for switching the lower mold 4 is set on the machine base 1. The drive unit includes electric guide rails 8 symmetrically installed on the machine base 1. A horizontal plate 9 is set on the machine base 1, and the horizontal plate 9 is connected to the output ends of the two sets of electric guide rails 8 for adjusting the position of the horizontal plate 9. A drive motor 10 is fixedly installed on the horizontal plate 9. The drive motor 10 is located in a sliding groove opened on the machine base 1. A rotating disk 11 is rotatably connected to the horizontal plate 9. The output end of the drive motor 10 is connected to the rotating disk 11 for driving the rotating disk 11 to rotate. A rectangular box 12 is fixedly installed on the rotating disk 11. Electric push rods 13 are symmetrically installed on the rectangular box 12. The output ends of the two sets of electric push rods 13 are fixedly installed with mounting bases 14 for driving the mounting bases 14 to move. The lower mold 4 is threadedly connected to the mounting base 14. A first magnetic suction plate 15 is fixedly installed at the bottom of the mounting base 14. Guide blocks 16 are integrally formed at the bottom of the mounting base 14 and on both sides of the first magnetic suction plate 15.

[0035] Here, the electric guide rail 8 can make slight position corrections to the horizontal plate 9, and together with the drive motor 10, drive the rotating disk 11 to rotate, realizing the rapid switching of the two sets of lower molds 4. This allows the other set of molds to complete loading and unloading while one set of molds is hot pressing, greatly improving the production efficiency of plastic artificial flowers.

[0036] Furthermore, the lower mold 4 and the mounting base 14 are connected by threads, which makes it easy to quickly change the corresponding mold according to different styles of artificial flowers, making it more versatile. The one-piece molded guide block 16 can improve the guiding accuracy when the mounting base 14 moves and avoid lateral deviation.

[0037] Furthermore, the electric push rod 13 is symmetrically arranged to drive the mounting base 14, ensuring balanced force and smooth movement. The sliding groove provides space for the drive motor 10 to move, avoiding structural interference. The entire drive system can achieve fully automatic station switching without requiring manual intervention near the hot pressing area, thus improving operational safety.

[0038] A support platform 5 for supporting the lower mold 4 is fixedly installed on the machine base 1. When the lower mold 4 is pressed against the support platform 5, it is fixed by a positioning component. The positioning component includes an opening groove 17 on the support platform 5 that is adapted to the first magnetic suction plate 15. An anti-slip pad 18 for pressing is fixedly installed on the inner wall of the closed side of the opening groove 17. A second magnetic suction plate 19 that attracts the first magnetic suction plate 15 is fixedly installed on the bottom wall of the opening groove 17. When the first magnetic suction plate 15 and the second magnetic suction plate 19 are magnetically attracted, the mounting base 14 and the anti-slip pad 18 abut against each other to form a positioning area. The support platform 5 is symmetrically provided with sliding grooves 20 that are adapted to the guide block 16. When in the positioning area, the guide block 16 is located in the sliding groove 20 and abuts against its inner wall.

[0039] Here, the support platform 5 provides stable support for the lower mold 4. The opening slot 17 cooperates with the first magnetic suction plate 15 and the second magnetic suction plate 19 to quickly achieve the initial magnetic positioning of the mounting base 14. The positioning response is fast and the positioning accuracy is high.

[0040] Furthermore, the anti-slip pad 18 abuts against the mounting base 14, which increases the friction of the contact surface and prevents the mounting base 14 from slipping during the hot pressing process. The slide groove 20 fits and limits the guide block 16, further constraining the displacement of the mounting base 14 and ensuring that the lower mold 4 and the upper mold 3 are always coaxial.

[0041] A rectangular through hole 21 is provided on the support platform 5. Slide rails 22 for sliding are symmetrically installed in the rectangular through hole 21. A toggle rod 23 is provided in the rectangular through hole 21. The toggle rod 23 is connected to the slider 24 in the corresponding slide rail 22. A spring 25 is provided in the slide rail 22, and the two ends of the spring 25 are connected to the slider 24 and the inner wall of the slide rail 22 respectively. A push rod 26 adapted to the toggle rod 23 is fixedly installed on the mounting base 14. When in the positioning area, the push rod 26 abuts against the toggle rod 23 and forms a pushing area.

[0042] Here, the rectangular through hole 21 provides installation and movement space for the lever 23. The slide rail 22 cooperates with the slider 24 to ensure that the lever 23 can only slide in a straight line, thus ensuring accurate and reliable transmission.

[0043] Furthermore, the spring 25 has an automatic reset function. When the push rod 26 separates from the toggle rod 23, it can drive the toggle rod 23 to return to its original position quickly, preparing for the next positioning action. No additional drive components are required, and the structure is simple and the operation is stable.

[0044] Furthermore, the contact and pushing of the push rod 26 and the toggle rod 23 is a purely mechanical linkage, with synchronous response and no lag. It can synchronously trigger subsequent limit actions following the positioning process of the mounting base 14, adapting to the high-speed continuous production rhythm.

[0045] A third magnetic plate 27 is fixedly mounted on the lever 23 via a frame, and a fourth magnetic plate 28 that attracts the third magnetic plate 27 is fixedly mounted on the push rod 26 via a frame. When in the push zone, the third magnetic plate 27 and the fourth magnetic plate 28 are magnetically attracted.

[0046] Here, the third magnetic plate 27 and the fourth magnetic plate 28 magnetically engage, allowing the push rod 26 and the actuating rod 23 to fit tightly together, preventing separation or jamming during the pushing process and ensuring the continuity of the linkage transmission.

[0047] Furthermore, the magnetic connection eliminates the need for mechanical clips and can automatically detach when the mounting base 14 retracts, ensuring both connection strength during positioning and rapid separation during unlocking, with smooth and unhindered operation.

[0048] A snap-fit ​​plate 29 is rotatably connected to the machine base 1 via a return spring on the upright. The snap-fit ​​plate 29 consists of a snap-fit ​​section and a toggle section. A positioning plate 30 adapted to the snap-fit ​​plate 29 is fixedly installed on the mounting base 14. When in the pushing zone, the toggle rod 23 contacts the toggle section, and the snap-fit ​​section snaps onto the positioning plate 30 to form a limiting zone. When the toggle rod 23 disengages from the toggle section, the snap-fit ​​section disengages from the positioning plate 30.

[0049] Here, the snap-fit ​​plate 29 and the positioning plate 30 snap together to form a mechanical limit, achieving secondary locking on the basis of magnetic positioning, effectively preventing the mold from loosening and shifting during hot pressing, and maximizing the molding accuracy of the plastic simulated flowers.

[0050] Furthermore, the reset spring can automatically rotate and reset the locking plate 29 after the toggle lever 23 is disengaged, thereby quickly releasing the limit and facilitating the smooth exit of the mounting base 14 from the support platform 5, thus improving the efficiency of workstation switching.

[0051] Furthermore, the integrated design of the toggle section and the latch section allows the toggle and latch actions to be completed simultaneously. The mechanical logic is clear, the failure rate is low, and the operator does not need to manually participate in the limit and unlocking. The entire process is automated, which further improves production safety.

[0052] In this invention, when the device is in operation, in the initial state, two sets of lower molds 4 are respectively installed on corresponding mounting bases 14. One set is located at the operator's loading / unloading position and contains raw materials to be hot-pressed, while the other set is located near the support platform 5, with no raw materials in the lower mold 4. Since the first hot pressing requires the use of a lower mold 4 with material, the drive motor 10 drives the rotating disk 11 to rotate, moving the lower mold 4 containing raw materials at the loading / unloading position to the area near the support platform 5. At the same time, the empty lower mold 4 originally near the support platform 5 is switched to the operator's loading / unloading position, and the operator simultaneously replenishes the empty lower mold 4 with raw materials. Subsequently, the electric guide rail 8 drives the horizontal... Plate 9 is finely adjusted to ensure that the lower mold 4 and the support platform 5 are precisely aligned. The electric push rod 13 on the rectangular box 12 is then activated, pushing the mounting base 14 corresponding to the lower mold 4 with material to move towards the support platform 5. The guide block 16 at the bottom of the mounting base 14 slides smoothly along the slide groove 20 of the support platform 5, providing guidance and limiting for the movement of the mounting base 14. As the mounting base 14 continues to move, the first magnetic suction plate 15 at its bottom and the second magnetic suction plate 19 in the opening groove 17 of the support platform 5 attract each other. At the same time, the mounting base 14 and the anti-slip pad 18 on the inner wall of the opening groove 17 are tightly pressed together. At this time, the lower mold 4 and the upper mold 3 are precisely coaxially aligned.

[0053] During this process, the push rod 26 on the mounting base 14 synchronously contacts and pushes the actuating rod 23 in the rectangular through hole 21 on the support platform 5. The fourth magnetic plate 28 on the push rod 26 and the third magnetic plate 27 on the actuating rod 23 attract each other, causing the actuating rod 23 to slide along the slide rail 22 with the slider 24 and compress the spring 25, thereby triggering the locking plate 29 to rotate. When the lower mold 4 and the upper mold 3 reach a completely coaxial state, the snap-fit ​​section of the locking plate 29 just snaps into the positioning plate 30 on the mounting base 14, forming a double positioning lock.

[0054] After positioning, heater 7 heats the upper mold 3 to the set temperature, and hydraulic cylinder 6 drives mounting bracket 2 and upper mold 3 to move downwards, closing with lower mold 4 to form a hot pressing zone, completing the three-dimensional hot pressing molding of plastic simulated flower raw material. After hot pressing, electric push rod 13 drives mounting base 14 to move backwards. The reserved movement allowance of the device provides space for the disengagement action. As mounting base 14 moves backwards, the first magnetic suction plate 15 and the second magnetic suction plate 19 disengage, and the third magnetic suction plate 27 and the fourth magnetic suction plate 28 separate synchronously. The spring in slide rail 22 25 restores its deformation, causing the slider 24 and the toggle lever 23 to reset. The locking plate 29 and the positioning plate 30 are released from their locking limit. The mounting base 14 completely exits the opening slot 17 of the support table 5. Then, the electric guide rail 8 drives the horizontal plate 9 to make a fine adjustment of its position. The drive motor 10 drives the rotating disk 11 to rotate, switching the lower mold 4 that has completed hot pressing to the operator's loading and unloading position. At the same time, another set of lower molds 4 that has been replenished with raw materials is moved to the hot pressing area near the support table 5. The above positioning and hot pressing process is repeated to achieve continuous automated production.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of the present invention.
