Description

Technical Field

[0001] The present invention relates to the technical field of physical foaming, in particular to a physical foaming device for an embryo and a demoulding method thereof. Background Art

[0002] The physical foaming device for the embryo body refers to a device specially designed to introduce bubbles into the "embroidery" material in an uncured, semi-finished state through physical methods (such as supercritical gas) and expand it to eventually form a foam structure.

[0003] The Chinese patent with announcement number CN215242384U discloses a reversible self-lifting foaming device, including a lower mold, a middle mold, an upper mold, a lifting core mold, a pad, a core mold fixing plate and a breathable pad material; the two ends of the middle mold are respectively connected to the lower mold and the upper mold, and a accommodating cavity is enclosed by the lower mold, the middle mold and the upper mold, the core mold fixing plate is connected to the upper mold, and there is a lifting space for the lifting core mold between the core mold fixing plate and the upper mold, the pad is installed on the core mold fixing plate, the lifting core mold includes mutually connected guide rods and a pressure plate, the pressure plate is embedded in the accommodating cavity, and a guide hole for inserting the guide rod is opened on the upper mold, and the top of the guide rod is facing the pad.

[0004] The above patent can effectively discharge the gas inside the foam material to avoid the occurrence of air pockets, glue shortages, scars, etc., and can form foam materials with special-shaped structural surfaces and multiple heights.

[0005] However, the above patents have the following shortcomings: the foaming material is easy to adhere to the inner wall of the mold, manual intervention or forced ejection is required during demolding, which can easily cause damage or deformation of the embryo, and the adhesion problem between the material and the mold is not solved. The embryo is easily torn due to local adhesion during demolding. There is a lack of a dynamic spraying mechanism, and the release agent is difficult to cover the complex mold cavity, affecting the demolding effect. There is a lack of an anti-fall locking structure during the lifting and lowering of the upper mold. If the hydraulic system fails, the upper mold may be accidentally pressed down, causing equipment damage or safety accidents.

[0017] A physical foaming demoulding method for an embryo body comprises the following steps: Step S1: The telescopic end of the hydraulic cylinder is controlled to extend, so that the telescopic end of the hydraulic cylinder drives the upper mold to move downward. During the movement, the release agent is delivered into the spraying mechanism by controlling the release agent delivery device external to the spraying mechanism. Driven by the movable mechanism, the spraying mechanism sprays the release agent onto the inner wall of the upper mold while adjusting the angle. Step S2: During the downward movement of the upper mold, the upper mold drives the piston rack to move downward along the inner side of the piston cylinder, so that the piston rack squeezes the gas in the piston cylinder into the inner side of the gas storage shell through the gas pipe. At the same time, driven by the movable mechanism, the vent assembly cooperates with the push plate to seal the upper mold, so that the gas is stored inside the gas storage shell. Step S3, when the foaming work is completed; control the telescopic end of the hydraulic cylinder to retract the fixed end, so that the upper mold moves upward, the ventilation component is gradually separated from the push plate, and the gas in the gas storage shell enters between the upper mold and the foaming material through the push plate. The upper mold continues to move upward, and the push plate is moved out of the upper mold through the abutment component, so that the push plate can push the foaming material in the upper mold. During the pushing process, the adhesion between the upper mold and the foaming material is reduced due to the influence of the vibration component, so that the push plate can push the foaming material out of the inner side of the upper mold; Step S4: When the upper mold moves upward, the upper mold drives the movable mechanism to move, which drives the ejection mechanism to move, which drives the interception mechanism to move between the movable mechanisms and form a locking connection with the movable mechanism to prevent the upper mold from losing control and pressing down.

[0018] The present invention provides an improved physical foaming device for embryos and a demoulding method thereof, which has the following improvements and advantages compared with the prior art: First, the present invention controls the upper mold to continue to move upward, so that the upper mold drives the push plate to move upward through the air storage shell and the second spring, so that the push plate drives the push rod to contact the abutment frame, so that the push plate moves out of the upper mold, so that the push plate can push the foaming material out of the inner side of the upper mold, thereby facilitating the demoulding of the foaming material; Second, the present invention controls the extension of the telescopic end of the hydraulic cylinder, so that the telescopic end of the hydraulic cylinder drives the upper mold to move downward. During the movement, the release agent is delivered to the inner side of the spray shell through the release agent delivery device externally connected to the control interface, and the spray shell sprays the release agent to the inner wall of the upper mold. At the same time, when the upper mold moves downward, it drives the first movable arm and the second movable arm to rotate, so that the first movable arm drives the spray shell to rotate around the connecting rod through the trigger rod, so that the spray mechanism sprays the release agent on the inner wall of the upper mold while adjusting the angle; Thirdly, the present invention drives the piston rack to move downward along the inner side of the piston cylinder during the downward movement of the upper mold, so that the piston rack squeezes the gas in the piston cylinder into the inner side of the gas storage shell through the gas pipe. At the same time, driven by the first movable arm, the force-bearing rod drives the blocking block through the plate frame and the round rod to cooperate with the push plate to seal the upper mold, so that the gas is stored in the inner side of the gas storage shell. When the foaming work is completed, the telescopic end of the hydraulic cylinder is controlled to retract the fixed end to move the upper mold upward, so that the force-bearing rod drives the blocking block through the plate frame and the round rod to gradually separate from the push plate, so that the gas in the gas storage shell enters between the upper mold and the foaming material through the push plate, so that gas flow is formed between the upper mold and the foaming material, and the gas flow is used to reduce the adhesion between the foaming material and the upper mold, which is beneficial to the demolding of the foaming material. Fourthly, in the present invention, when the upper mold begins to move upward, the expansion speed of the first movable arm and the second movable arm is relatively slow relative to the movement of the telescopic end of the hydraulic cylinder. Moreover, due to the rotation of the hinge between the first movable arm, the force-bearing rod and the plate frame, when the telescopic end of the hydraulic cylinder drives the upper mold and the push plate to move upward, the upward movement speed of the blocking block cannot keep up with the speed of the upper mold and the push plate. At this time, the blocking block is slightly moved out of the inner side of the push plate, so that the blocking block can push the foaming material stuck to the push plate, thereby facilitating the separation between the push plate and the foaming material. Fifth, the present invention uses the push plate to drive the sawtooth frame to move during the pushing process. The third spring can use its own elastic force to support the clamping plate, so that the sawtooth frame can continue to be clamped with the clamping plate. The clamping creates vibration, which reduces the adhesion between the upper mold and the foaming material affected by the vibration, thereby facilitating the push plate to push the foaming material and avoiding damage to the foaming material caused by the push plate forcibly pushing the foaming material. Sixth: In the present invention, when the upper mold moves upward, the upper mold drives the first movable arm to move, so that the first movable arm drives the abutment block to move through the fixed shell, the telescopic block, the support rod and the interface, so that the abutment block abuts against the guide shell, and the guide shell drives the clamping block to move between the first movable arm and the second movable arm through the side block under the support of the first spring elastic force, forming a clamping connection between the first movable arm and the second movable arm to prevent the upper mold from losing control and pressing down.

[0024] In this embodiment, the movable mechanism includes a first movable arm 8 hingedly mounted on the upper mold 4, and a second movable arm 9 hingedly mounted on the lower mold 7 and hingedly connected to the first movable arm 8.

A connecting rod 19 fixed to the spray shell 15 is rotatably mounted on the ring block 18, and a trigger rod 20 is fixedly mounted on the spray shell 15.

[0025] Specifically, the interface 13 is connected to an external release agent delivery device, and the delivery pipe 14 is a hose. The staff controls the telescopic end of the hydraulic cylinder 3 to extend, so that the telescopic end of the hydraulic cylinder 3 drives the upper mold 4 to move downward. During the movement, the release agent delivery device connected to the control interface 13 is used to deliver the release agent to the inner side of the spray shell 15, and the spray shell 15 sprays the release agent onto the inner wall of the upper mold 4. At the same time, when the upper mold 4 moves downward, it drives the first movable arm 8 and the second movable arm 9 to rotate, so that the first movable arm 8 drives the spray shell 15 to rotate around the connecting rod 19 through the trigger rod 20, so that the spray mechanism sprays the release agent onto the inner wall of the upper mold 4 while adjusting the angle. When the upper mold 4 moves upward, the torsion spring 17 can use its own elastic force to drive the spray shell 15 to reset and rotate through the ring block 18 and the connecting rod 19.

[0026] In this embodiment, the intercepting mechanism includes two abutment blocks 21 respectively fixedly mounted on the two interfaces 13, two sets of side plates 22 are fixedly mounted on the top frame 2, each side plate 22 is connected to a first spring 23, the end of the first spring 23 is connected to a side block 24, a guide shell 25 fixed to the top frame 2 is fixedly mounted on the side block 24, the guide shell 25 abuts against the abutment block 21, and a clamping block 26 is fixedly mounted on the guide shell 25.

[0027] Specifically, when the upper mold 4 moves upward, the upper mold 4 drives the first movable arm 8 to move, so that the first movable arm 8 drives the abutment block 21 to move through the fixed shell 10, the telescopic block 11, the support rod 12 and the interface 13, so that the abutment block 21 abuts against the guide shell 25, so that the guide shell 25 drives the clamping block 26 to move between the first movable arm 8 and the second movable arm 9 through the side block 24 under the support of the elastic force of the first spring 23, forming a clamping connection between the first movable arm 8 and the second movable arm 9, thereby preventing the upper mold 4 from being pressed down uncontrollably; When the upper mold 4 moves downward, the abutment block 21 no longer abuts against the guide shell 25, so that the first spring 23 can use its own elastic force to drive the guide shell 25 to reset through the side block 24, so that the blocking block 26 moves away from between the first movable arm 8 and the second movable arm 9.

[0028] In this embodiment, the blanking mechanism includes two gas storage shells 27 fixedly mounted on the upper mold 4, two second springs 28 are connected to the inner side of the top wall of each gas storage shell 27, the ends of the two second springs 28 are commonly connected to a push plate 29 slidably connected to the upper mold 4, an abutment component is commonly provided between the top frame 2 and the push plate 29, a vibration component is commonly provided between the gas storage shell 27 and the push plate 29, a plurality of piston racks 36 are fixedly mounted on the upper mold 4, a piston cylinder 37 slidably connected to the piston rack 36 is fixedly mounted on the lower mold 7, an air intake one-way valve 38 is provided on the piston cylinder 37, an air supply pipe 39 fixed to the gas storage shell 27 is fixedly mounted on the piston cylinder 37, a ventilation component is commonly provided between the movable mechanism and the gas storage shell 27, and the abutment component includes a plurality of piston racks 36, a piston cylinder 37 slidably connected to the piston rack 36 is fixedly mounted on the lower mold 7, an air intake one-way valve 38 is provided on the piston cylinder 37, and an air supply pipe 39 fixed to the gas storage shell 27 is fixedly mounted on the piston cylinder 37. The support frame 31 is fixedly mounted on the top frame 2, and a push rod 30 is fixedly mounted on the push plate 29. The vibration assembly includes two inner shells 32 symmetrically fixedly mounted on the inner wall of the air storage shell 27. The inner wall of each inner shell 32 is connected to a plurality of third springs 33. The ends of the plurality of third springs 33 are commonly connected to a card plate 34 that is slidably connected to the inner shell 32. Two serrated frames 35 that are clamped with the card plate 34 are symmetrically fixedly mounted on the push plate 29. The ventilation assembly includes a plurality of force-bearing rods 40 that are respectively hingedly mounted on a plurality of first movable arms 8. The ends of each two force-bearing rods 40 are commonly hingedly mounted with a plate frame 41. Two round rods 42 are fixedly mounted on the plate frame 41. The end of each round rod 42 is fixedly mounted with a blocking block 43 that is slidably connected to the push plate 29.

[0029] Specifically, a check valve is provided in the gas pipe 39 to prevent gas backflow. During the downward movement of the upper mold 4, the upper mold 4 drives the piston rack 36 to move downward along the inner side of the piston cylinder 37, so that the piston rack 36 squeezes the gas in the piston cylinder 37 into the inner side of the gas storage shell 27 through the gas pipe 39. At the same time, driven by the first movable arm 8, the force rod 40 drives the block 43 through the plate frame 41 and the round rod 42 to cooperate with the push plate 29 to seal the upper mold 4, so that the gas is stored in the gas storage On the inner side of the shell 27, when the foaming work is completed, the telescopic end of the hydraulic cylinder 3 is controlled to retract to the fixed end, so that the upper mold 4 moves upward, and the force-bearing rod 40 drives the blocking block 43 to gradually separate from the push plate 29 through the plate frame 41 and the round rod 42, so that the gas in the gas storage shell 27 enters between the upper mold 4 and the foaming material through the push plate 29, so that gas flow is formed between the upper mold 4 and the foaming material, and the gas flow is used to reduce the adhesion between the foaming material and the upper mold 4, which is conducive to the demoulding of the foaming material; During the initial upward movement of the upper mold 4, the expansion speed of the first movable arm 8 and the second movable arm 9 is relatively slow relative to the movement of the telescopic end of the hydraulic cylinder 3. Moreover, due to the rotation of the hinge between the first movable arm 8, the force-bearing rod 40 and the plate frame 41, when the telescopic end of the hydraulic cylinder 3 drives the upper mold 4 and the push plate 29 to move upward, the upward movement speed of the block 43 cannot keep up with the speed of the upper mold 4 and the push plate 29. At this time, the block 43 is slightly moved out of the inner side of the push plate 29, so that the block 43 can push the foaming material adhering to the push plate 29, thereby facilitating the separation between the push plate 29 and the foaming material. Subsequently, the first movable arm 8 drives the block 43 to move upward through the force-bearing rod 40, the plate frame 41 and the round rod 42. As the upper mold 4 continues to move upward, the expansion speed of the first movable arm 8 and the second movable arm 9 gradually increases, causing the blocking block 43 to move upward and gradually overtake the push plate 29; By controlling the upper mold 4 to continue to move upward, the upper mold 4 drives the push plate 29 to move upward through the air storage shell 27 and the second spring 28, so that the push plate 29 drives the push rod 30 to contact the abutment frame 31, so that the push plate 29 moves out of the upper mold 4, so that the push plate 29 can push the foaming material out of the inner side of the upper mold 4, thereby facilitating the demoulding of the foaming material; When the upper mold 4 moves downward, the abutment force between the push rod 30 and the abutment frame 31 decreases, so that the second spring 28 can use its own elastic force to drive the push plate 29 to move into the inner side of the upper mold 4 for reset; During the pushing process, the push plate 29 drives the serrated frame 35 to move, and the third spring 33 can use its own elastic force to support the clamping plate 34, so that the serrated frame 35 can continue to be clamped with the clamping plate 34, and vibration is generated by the clamping, so that the adhesion between the upper mold 4 and the foaming material is reduced due to the vibration, which is conducive to the push plate 29 pushing the foaming material and avoids damage to the foaming material caused by the push plate 29 forcibly pushing the foaming material.

[0030] A physical foaming demoulding method for an embryo body comprises the following steps: Step S1: The telescopic end of the hydraulic cylinder 3 is controlled to extend, so that the telescopic end of the hydraulic cylinder 3 drives the upper mold 4 to move downward. During the movement, the release agent is delivered to the spraying mechanism by controlling the release agent delivery device external to the spraying mechanism. Driven by the movable mechanism, the spraying mechanism sprays the release agent onto the inner wall of the upper mold 4 while adjusting the angle. Step S2: During the downward movement of the upper mold 4, the upper mold 4 drives the piston frame 36 to move downward along the inner side of the piston cylinder 37, so that the piston frame 36 squeezes the gas in the piston cylinder 37 into the inner side of the gas storage shell 27 through the gas pipe 39. At the same time, driven by the movable mechanism, the vent assembly cooperates with the push plate 29 to seal the upper mold 4, so that the gas is stored inside the gas storage shell 27. Step S3: When the foaming work is completed, the telescopic end of the hydraulic cylinder 3 is controlled to retract to the fixed end, so that the upper mold 4 moves upward, the ventilation component is gradually separated from the push plate 29, and the gas in the gas storage shell 27 enters between the upper mold 4 and the foaming material through the push plate 29. The upper mold 4 continues to move upward, and the push plate 29 is moved out of the upper mold 4 through the abutment component, so that the push plate 29 can push the foaming material in the upper mold 4. During the pushing process, the adhesion between the upper mold 4 and the foaming material is reduced due to the influence of the vibration component, so that the push plate 29 can push the foaming material out of the inner side of the upper mold 4; Step S4, when the upper mold 4 moves upward, the upper mold 4 drives the movable mechanism to move, and the movable mechanism drives the ejection mechanism to move, and the ejection mechanism drives the interception mechanism to move between the movable mechanisms, forming a card connection with the movable mechanism to prevent the upper mold 4 from being pressed down uncontrollably.

[0031] Working principle: The staff controls the extension of the telescopic end of the hydraulic cylinder 3. During the movement, the release agent is transported to the inner side of the spray shell 15 through the release agent delivery device connected to the control interface 13, and the spray shell 15 sprays the release agent to the inner wall of the upper mold 4. At the same time, when the upper mold 4 moves downward, it drives the first movable arm 8 and the second movable arm 9 to rotate, so that the first movable arm 8 drives the spray shell 15 to rotate around the connecting rod 19 through the trigger rod 20, so that the spray mechanism sprays the release agent on the inner wall of the upper mold 4 while adjusting the angle, so that the telescopic end of the hydraulic cylinder 3 can drive the upper mold 4 to move downward and fit with the lower mold 7, and the upper mold 4 is brought The movable piston frame 36 moves downward along the inner side of the piston cylinder 37, so that the piston frame 36 squeezes the gas in the piston cylinder 37 into the inner side of the gas storage shell 27 through the gas pipe 39. At the same time, driven by the first movable arm 8, the force-bearing rod 40 drives the blocking block 43 through the plate frame 41 and the round rod 42 to cooperate with the push plate 29 to seal the upper mold 4, so that the gas is stored inside the gas storage shell 27. The embryo material is transported between the upper mold 4 and the lower mold 7 by controlling the external embryo material transport device. The supercritical gas is also transported between the upper mold 4 and the lower mold 7 by controlling the external supercritical gas transport device, so that the supercritical gas physically foams the embryo material. After foaming is completed, the telescopic end of the hydraulic cylinder 3 is controlled to retract the fixed end, so that the upper mold 4 moves upward, and the circular sleeve drives the blocking block 43 to gradually separate from the push plate 29 through the fourth spring, movable rod, plate frame 41 and round rod 42, so that the gas in the gas storage shell 27 enters between the upper mold 4 and the foaming material through the push plate 29, so that gas flow is formed between the upper mold 4 and the foaming material, and the gas flow is used to reduce the adhesion between the foaming material and the upper mold 4. By controlling the upper mold 4 to continue to move upward, the upper mold 4 is driven by the gas storage shell 27 and the second spring 28 to move the push plate 29 upward, so that the push plate 29 drives the push rod 30 to contact the abutment frame 31, so that the push plate 29 moves out of the upper mold 4, so that the push plate 29 can push the foaming material out of the inner side of the upper mold 4. When the upper mold 4 just starts to move upward, the expansion speed of the first movable arm 8 and the second movable arm 9 is relative to that of the liquid The telescopic end of the pressure cylinder 3 moves relatively slowly, and due to the rotation of the hinge between the first movable arm 8, the force-bearing rod 40 and the plate frame 41, the telescopic end of the hydraulic cylinder 3 drives the upper mold 4 and the push plate 29 to move upward. The upward movement speed of the block 43 cannot keep up with the speed of the upper mold 4 and the push plate 29. At this time, the block 43 moves slightly out of the inner side of the push plate 29, so that the block 43 can push the foaming material adhering to the push plate 29, which is convenient for the push plate 29 to separate from the foaming material. During the pushing process of the push plate 29, the push plate 29 drives the serrated frame 35 to move. The third spring 33 can use its own elastic force to support the card plate 34, so that the serrated frame 35 can continue to be clamped with the card plate 34, and vibration is generated by the clamping, so that the adhesion between the upper mold 4 and the foaming material is reduced due to the vibration, which is convenient for the push plate 29 to push the foaming material out of the inner side of the upper mold 4.

During the movement, the release agent is conveyed into the spraying mechanism by controlling the release agent conveying device connected to the spraying mechanism. Driven by the movable mechanism, the spraying mechanism sprays the release agent onto the inner wall of the upper mold (4) while adjusting the angle. Step S2: During the downward movement of the upper mold (4), the upper mold (4) drives the piston rack (36) to move downward along the inner side of the piston cylinder (37), so that the piston rack (36) squeezes the gas in the piston cylinder (37) into the inner side of the gas storage shell (27) through the gas pipe (39).
