Description

Technical Field

[0001] This invention relates to the technical field of hot presses, and more particularly to a hot press based on seamless hot pressing one-time forming. Background Technology

[0002] Existing hot presses have significant drawbacks in achieving "seamless one-time molding": during the mold closing stage, errors caused by the coordination of multiple power sources can easily lead to platen misalignment; spliced ​​molds are prone to leaving seam marks on the workpiece surface and have insufficient sealing, making it difficult to eliminate overflow and flash. During demolding, rigid ejection mechanisms can easily damage the workpiece surface or cause deformation of thin-walled parts, while manual demolding is inefficient and poses safety hazards.

[0003] Furthermore, the asynchronous operation of the pressing and molding processes often leads to material displacement. Coupled with the lack of an effective anti-sticking mechanism, this results in difficulties in demolding high-viscosity composite materials, making it difficult to guarantee yield and failing to meet the quality requirements of high-end manufacturing for unibody products. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, the purpose of this invention is to propose a hot press based on seamless hot pressing one-time molding. Through the cooperation of the transmission screw and the guide groove, the pressing material and the sealing component are ensured to descend vertically and synchronously. Combined with the full coverage and sealing of the opening groove of the molding cavity by the molding plate, the seams and overflow are completely eliminated, realizing true one-piece seamless molding. The elastic lifting of the reset part, combined with the micro-amplitude reciprocating vibration of the positioning block driven by the conveyor belt, effectively breaks the adsorption and adhesion between the molded part and the cavity wall, avoiding surface indentations or thin-wall deformation caused by rigid ejection. A single rotary drive source links the pressing and molding processes, simplifying the control logic. The positioning rod is guided by the side partition plate to prevent swaying, significantly improving the equipment utilization rate and product yield.

[0006] To achieve the above objectives, the present invention proposes a hot press based on seamless hot pressing one-time forming, including a base plate, a sealing assembly on one side of the base plate, a transmission assembly on one side of the base plate, a driven plate connected to the movable end of the transmission assembly, and the driven plate connected to the sealing assembly; The sealing assembly includes an inner forming mechanism disposed on one side of the base plate.

[0018] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention. Rather, embodiments of the invention include all variations, modifications, and equivalents falling within the appended spirit and scope.

[0019] The following describes, with reference to the accompanying drawings, a hot press based on seamless hot pressing one-time forming according to an embodiment of the present invention.

[0020] like Figure 1-7 As shown, the hot press based on seamless hot pressing one-time molding in this embodiment of the invention includes a base plate 10, a sealing assembly 20 is provided on one side of the base plate 10, a transmission assembly 30 is provided on one side of the base plate 10, the movable end of the transmission assembly 30 is connected to the driven plate 40, and the driven plate 40 is connected to the sealing assembly 20.

[0021] Two sets of side partitions are provided in the middle of the top wall of the base plate 10. Through grooves are provided on the partitions, and the through grooves guide the movable end in the transmission assembly 30.

[0022] The sealing assembly 20 includes an inner forming mechanism 201 disposed on one side of the base plate 10. An upper pressing member 202 connected to the transmission assembly 30 is disposed on one side of the inner forming mechanism 201. An outer cover 204 is disposed on the top wall of the upper pressing member 202. A lifting drive 205 is disposed on the top wall of the outer cover 204. A guide shaft 203 is disposed between the upper pressing member 202 and the inner forming mechanism 201. A molding member 206 connected to the lifting drive 205 is disposed inside the upper pressing member 202.

[0023] It should be noted that the inner forming mechanism 201 provides a pre-formed forming space for the workpiece to be formed. The inner forming mechanism 201 is supported by a column set on the top wall of the base plate 10 to ensure the structural stability of the inner forming mechanism 201 and prevent displacement due to high pressure during hot pressing. The opening slot opened on the inner side wall of the cavity reserves the movement space for the inner driven mechanism 2015, and the height of the opening slot is less than the height of the molding plate 2061. This not only limits the maximum upward stroke of the inner driven mechanism and prevents the positioning block 20155 from coming out of the through slot of the molding plate, but also ensures that the molding plate can completely cover the cavity when the mold is closed, without any pressure blind spots.

[0024] The inner forming mechanism 201 includes a forming cavity 2011 disposed on one side of the base plate 10. One end of the forming cavity 2011 embedded in the inner side of the base plate 10 is provided with a positioning frame 2012. The inner side of the positioning frame 2012 is provided with a movable plate 2013. The side of the forming cavity 2011 near the upper pressure member 202 is provided with a positioning hole 2014. The inner side of the forming cavity 2011 is provided with an inner driven mechanism 2015.

[0025] It should be noted that the positioning frame 2012 provides installation support for the movable plate 2013. The movable plate 2013 is directly connected to the inner driven mechanism 2015, which moves up and down inside the molding cavity 2011. When the pressing mechanism 305 in the transmission assembly 30 moves down, the pressing mechanism 305 moves down and presses against the movable plate 2013, thereby driving the entire inner driven mechanism 2015 to move down.

[0026] The internal driven mechanism 2015 includes a lifting rod 20151 disposed inside the molding cavity 2011. One end of the lifting rod 20151 extending to the inside of the positioning frame 2012 is connected to a driven rod 20152. The bottom wall of the driven rod 20152 is provided with a reset part 20153. A conveyor wheel 20154 is provided inside the molding cavity 2011. A conveyor belt 20156 is sleeved on the conveyor wheel 20154. A positioning block 20155 connected to one side of the lifting rod 20151 is provided on the conveyor belt 20156.

[0027] It should be noted that, in this embodiment, the lifting rod 20151 and the driven rod 20152 move synchronously. A positioning hole 2014 is provided on the top wall of the molding cavity 2011, and a guide shaft 203 is provided on the bottom wall of the upper pressing member 202 to move through the positioning hole 2014. When the guide shaft 203 moves downward, it presses against the driven rod 20152 and the lifting rod 20151. After the mold is closed, the through groove 2063 on the molding plate 2061 passes through the positioning block 20155 when it moves downward, and the molding plate 2061 seals the through groove opened inside the molding cavity 2011 when it moves downward. When the positioning block 20155 moves to the bottom, it contacts the surface of the molded part after the molding is completed. During demolding, the molding plate 2061 resets, and the positioning block 20155 resets with the elastic upward movement of the reset part 20153. At this time, the conveyor wheel 20154 drives the conveyor belt 20156 to move back and forth left and right. The positioning block applies a displacement force to the molded part from the inner wall of the molding cavity 2011.

[0028] The transmission assembly 30 includes a rotary drive 301 disposed on the top wall of the base plate 10. The output end of the rotary drive 301 is connected to a transmission screw 302. The outer wall of the transmission screw 302 is threadedly connected to an internal threaded collar 303. Positioning rods 304 are respectively connected to both sides of the internal threaded collar 303. A pressing mechanism 305 is provided on the bottom wall of the positioning rod 304.

[0029] It should be noted that the rotary drive 301 described in this embodiment provides power for the entire feeding process, and uses a servo motor to precisely control the output speed and torque. By operating the rotary drive 301 and controlling the rotation angle of the motor, the number of rotations of the transmission screw is precisely adjusted, thereby achieving millimeter-level control of the feed amount to adapt to material processing requirements of different heights. The transmission screw 302 adopts a helical transmission mechanism, featuring high precision and strong self-locking. The internal threaded collar 303 is threadedly connected to the transmission screw 302, and the rotary drive 301 drives the internal threaded collar 303 to rise and fall on the transmission screw 302 to adjust its height. The two ends of the positioning rod 304 are respectively connected to the internal threaded collar 303 and the upper pressure component 202. During the movement, it is always limited by the guide groove of the side partition, ensuring the perpendicularity of the movement trajectory and preventing the sealing assembly from swaying.

[0030] In one embodiment of the present invention, such as Figure 6 As shown, the pressing mechanism 305 includes a fixed connector 3054 disposed on the bottom wall of the positioning rod 304. The fixed connector 3054 is connected to a fixed shaft rod 3051. An active pressing rod 3052 is sleeved on the fixed shaft rod 3051. A driven pressing rod 3053 is provided on one side of the active pressing rod 3052.

[0031] It should be noted that the fixed connecting member 3054 in the pressing mechanism 305 is connected to the internal threaded collar 303 by a fixed rod. As the internal threaded collar 303 moves up and down, during the downward movement, the active pressing rod 3052 and the driven pressing rod 3053 are inserted into the positioning frame 2012 and abut against the movable plate 2013, thereby enhancing the stability of the movable plate 2013 and the internal driven mechanism 2015.

[0032] In one embodiment of the present invention, such as Figure 7 As shown, the molding component 206 includes a fixed column 2062 connected to the output end of the lifting drive 205. The bottom wall of the fixed column 2062 is provided with a molding plate 2061. The molding plate 2061 is provided with multiple sets of through grooves 2063. The through grooves 2063 are sleeved on the outside of the positioning block 20155.

[0033] It should be noted that the molding plate 2061 in the molding part 206 has a through groove 2063 on its side. During the downward movement of the molding plate 2061, the through groove 2063 will pass through the positioning block 20155. During the downward movement of the molding plate 2061, it will back seal and block the molding cavity 2011, and then perform hot pressing molding.

[0034] In one embodiment of the present invention, such as Figure 3 As shown, there is a gap between the positioning frame 2012 and the movable plate 2013.

[0035] It should be noted that a gap is left between the positioning frame 2012 and the movable plate 2013 to allow space for the active pressure rod 3052 and the driven pressure rod 3053 to fit and connect during the downward movement.

[0036] In one embodiment of the present invention, such as Figure 3 As shown, the inner wall of the molding cavity 2011 is provided with an opening groove for the inner driven mechanism 2015 to move, and the height of the opening groove is less than the height of the molding plate 2061.

[0037] It should be noted that an opening groove is provided in the molding cavity 2011. The height of the opening groove is less than the height of the molding plate 2061. After the molding plate 2061 is embedded in the molding cavity 2011, it can maintain the sealing of the inside of the molding cavity 2011.

[0038] Specifically, the seamless hot pressing molding steps of this application are as follows: 1. Initial standby and positioning phase: Before the equipment is started, the molding part 206 is in the upper position, the internal driven mechanism 2015 is in the upper position under the action of the reset part 20153, and the positioning block 20155 is located inside the molding cavity 2011. At this time, the rotation drive 301 of the transmission assembly 30 is not started, the internal threaded collar 303 is located on the side of the transmission screw 302 near the top, and the pressing mechanism 305 and the upper pressing part 202 connected to it are both in the raised state.

[0039] The operator places the sheet material or preform to be processed inside the forming cavity 2011. A gap is left between the positioning frame 2012 and the movable plate 2013 to allow space for the intervention of subsequent mechanisms.

[0040] 2. Mold closing and cavity sealing stage: Power transmission: The rotary drive 301 is preferably started by a servo motor, which precisely controls the rotation angle and drives the transmission screw 302 to rotate. Through the screw drive, the internal threaded collar 303 moves linearly downward along the screw.

[0041] Synchronous pressing: The internal threaded collar 303 drives the positioning rods 304 on both sides to move down. One end of the positioning rod 304 is constrained by the guide groove of the side partition of the bottom plate 10 to ensure verticality and prevent swaying.

[0042] Material pressing and guiding: The material pressing mechanism 305 at the bottom of the positioning rod 304 descends accordingly. The active pressing rod 3052 and the driven pressing rod 3053 are inserted into the gap of the positioning frame 2012, pressing the movable plate 2013.

[0043] Simultaneously, the other end of the positioning rod 304 drives the upper pressing component 202 to move downward along the guide shaft 203. The guide shaft 203 at the bottom of the upper pressing component 202 is inserted into the positioning hole 2014 at the top of the molding cavity 2011 to achieve precise guidance and initial positioning.

[0044] Cavity sealing: As the upper pressure member 202 moves downward, the molding plate 2061 in the molding member 206 gradually approaches the molding cavity 2011. Since the height of the opening groove on the inner wall of the molding cavity 2011 is less than the height of the molding plate 2061, when the molding plate 2061 is completely inserted into the cavity, it can completely cover and seal the opening groove, ensuring the airtightness of the molding cavity, preventing overflow or air from entering, and creating conditions for seamless molding.

[0045] 3. Hot pressing stage: Molding action: After the upper pressing component 202 is in place, the lifting drive 205, such as a hydraulic cylinder or an electric cylinder, is activated to push the fixed column 2062 and the molding plate 2061 further downward.

[0046] Avoidance and fit: During the downward movement, the multiple through slots 2063 on the molding plate 2061 are precisely fitted onto the outside of the positioning block 20155 of the inner driven mechanism 2015, achieving zero interference passage. The bottom surface of the molding plate 2061 is finally pressed tightly against the material surface on the movable plate 2013.

[0047] Heat transfer and molding: The molding plate 2061 and the molding cavity 2011 are usually equipped with heating devices, which are not shown in the figure, but are a standard configuration for hot pressing. Heat is transferred to the material, causing it to soften or melt; at the same time, the high pressure applied by the molding plate 2061 causes the softened material to flow in the closed molding cavity 2011 and fill the cavity, completing a one-time seamless hot pressing molding under the combined action of pressure and temperature.

[0048] 4. Demolding and resetting stage: Molding reset: After hot pressing and pressure holding are completed, the lifting drive 205 retracts, causing the molding plate 2061 to move upward. The through groove 2063 of the molding plate 2061 separates from the positioning block 20155.

[0049] Internal driven ejection and anti-sticking: The rotary drive 301 reverses, driving the internal threaded collar 303 to move upward through the transmission screw 302, and the pressing mechanism 305 no longer presses the movable plate 2013. At this time, the reset part 20153 of the internal driven mechanism 2015 is usually a spring or cylinder that releases potential energy, pushing the driven rod 20152 and the lifting rod 20151 upward.

[0050] Micro-motion demolding: As the lifting rod 20151 moves upward, the conveyor wheel 20154 starts, driving the conveyor belt 20156 to move back and forth a short distance. The positioning block 20155 fixed on the conveyor belt 20156 moves back and forth accordingly, applying a small shearing force and vibration to the surface of the molded part that is in close contact with the inner wall of the molding cavity 2011, breaking the vacuum adsorption force and adhesion force between the molded part and the cavity wall, so that the finished product can be smoothly detached from the cavity wall.

[0051] Overall reset: The rotary drive 301 continues to operate until the pressing mechanism 305 and the upper pressing component 202 are fully reset. The inner driven mechanism 2015 remains in the highest position under the action of the reset part, waiting for the next cycle. The operator can then remove the seamless workpiece after forming.

[0052] In summary, the hot press based on seamless hot pressing in this embodiment of the invention, through the cooperation of the transmission screw and the guide groove, ensures that the pressing material and the sealing component descend vertically and synchronously. Combined with the full coverage and sealing of the opening groove of the molding cavity by the molding plate, it completely eliminates seams and overflow, achieving true one-piece seamless molding. The elastic lifting of the reset part, combined with the micro-amplitude reciprocating vibration of the positioning block driven by the conveyor belt, effectively breaks the adsorption and adhesion between the molded part and the cavity wall, avoiding surface indentations or thin-wall deformation caused by rigid ejection. The single rotary drive source links the pressing and molding processes, simplifying the control logic. The positioning rod is guided by the side partition plate to prevent swaying, significantly improving the equipment utilization rate and product yield.

Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention.
