Abstract
Description
Technical Field
[0001] This invention relates to the field of packaging material molding technology, specifically to an intelligent hot pressing molding equipment and method. Background Technology
[0002] Hot-press molding equipment is widely used in the packaging and shaping processes of polymer materials such as medical dressings and irregularly shaped flexible packaging. This type of equipment mainly relies on the actuator to drive the heated mold to press down, so that the packaging material will undergo local melting and bonding under specific temperature and pressure, thereby completing the heat sealing action.
[0003] In existing technologies, for hot pressing processes requiring continuous operation, the typical approach is to use a constant-temperature hot-pressing metal block that integrates the heating element and the pressing mold. During a single work cycle, the actuator drives the constant-temperature hot-pressing metal block downwards and into contact with the workpiece surface. Solid-state heat conduction causes the polymer material surface to reach its melting point and enter a viscous flow state. After a predetermined welding time, the actuator drives the metal block to axially displace, detaching it from the workpiece and thus completing demolding.
[0004] However, the above-mentioned existing technologies have the following shortcomings: In the hot pressing process, in order to avoid the material from deforming at high temperature, the workpiece must be kept under physical pressure for cooling and shaping after welding. Since the heating source and the pressing surface of the existing technology are a rigid integrated structure with a large total system heat capacity, if the demolding is lifted directly after melting, the polymer material in the viscous flow state will instantly lose its external physical constraint, and its surface will show stringing or shrinkage deformation, affecting the flatness of the seal. If the power is cut off and forced cooling is performed under the pressure holding state in order to achieve cooling and shaping, the large heat capacity of the integrated structure makes the cooling rate of dissipating residual heat to the external environment low.
[0005] Furthermore, when entering the next work cycle, the large heat capacity metal block must be reheated as a whole, which directly affects production efficiency, and the energy consumption generated by repeatedly heating the huge metal entity is large. Summary of the Invention
[0006] The purpose of this invention is to provide an intelligent hot pressing molding equipment and method, which overcomes the contradiction between the large heat capacity and rapid cooling of the hot pressing module by designing the high-temperature heat source module and the heat transfer module separately.
[0007] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: A smart hot press molding machine includes a gantry frame and a mounting frame that can slide horizontally along the gantry frame. It also includes: a lifting frame; a lifting assembly mounted on the mounting frame, with its movable end fixedly connected to the lifting frame for controlling the vertical lifting of the lifting frame; a hot press execution system mounted on the lifting frame, comprising, from top to bottom, a high-temperature heat source module, a heat transfer module, and a hot press module; the heat transfer module includes a heat-conducting cylinder, and the hot press module is connected to the bottom surface of the heat-conducting cylinder; a support column is fixedly connected to the center of the inner cavity of the heat-conducting cylinder; and a central exhaust channel is opened in the support column of the heat transfer module, with the upper end of the central exhaust channel connected to a pipe. It is connected to a fan that is independently installed outside the equipment; a clutch actuation component is installed between the high-temperature heat source module and the heat transfer module; the clutch actuation component is used to drive the high-temperature heat source module to move relative to the heat transfer module, and it is configured such that: when the lifting frame performs a downward pressing stroke, the clutch actuation component causes the bottom surface of the high-temperature heat source module to enter a physical fit with the inner cavity of the heat transfer module; when the lifting frame performs an upward demolding stroke, the clutch actuation component forces the high-temperature heat source module and the heat transfer module to physically separate, so as to form a broken bridge gap between them; the broken bridge gap is connected to the lower opening of the central exhaust channel.
[0008] By adopting the above technical solution and setting a clutch action component, the high-temperature heat source module and the heat transfer module are physically attached during the pressing stroke, and heat is conducted through direct contact between the objects; while during the demolding stroke, the two are physically separated and form a broken bridge gap, cutting off the heat input of the heat source from the physical conduction path, so that during the cooling and shaping stage, the equivalent metal heat capacity participating in heat dissipation is less than the total heat capacity of the traditional one-piece mold.
[0009] Furthermore, by utilizing the central exhaust channel located inside the support column and connecting it to the gap of the broken bridge, an external fan draws in air to generate a centripetal negative pressure airflow, forcibly removing the heat trapped in the gap. This improves the heat dissipation rate of the inner wall of the heat-conducting cylinder and shortens the cooling and shaping time of the workpiece, thereby overcoming the contradiction between large heat capacity and rapid cooling.
[0010] A further improvement of the technical solution of the present invention is that: the clutch action assembly includes at least two guide rods fixed to the lifting frame and extending vertically downward, and a first spring sleeved on the outside of the guide rods; the bottom of each guide rod is fixedly connected to an isolation column; a high-temperature heat source module is fixed between the bottoms of the isolation columns, and a through hole extending axially is opened at the axial center of the high-temperature heat source module; a sliding plate is fixedly connected to the top of the support column, and the sliding plate has a sliding hole adapted to the guide rod, and the sliding plate is slidably sleeved on the guide rod through the sliding hole; the upper end of the first spring abuts against the lifting frame, and its lower end abuts against the sliding plate.
[0011] By adopting the above technical solution, a purely mechanical passive engagement and disengagement between the high-temperature heat source module and the heat transfer module is achieved by setting a first spring sleeved outside the guide rod and a support column passing through the through hole of the high-temperature heat source module and connecting to the slide plate. This solution utilizes the reaction force generated by the workpiece when pressing downward to compress the first spring to achieve physical contact between the modules, and utilizes the potential energy released by the first spring when demolding upward to achieve physical separation between the modules. This eliminates the need for an additional clutch drive source and simplifies the control logic of the equipment. At the same time, placing the first spring and the slide plate above the high-temperature heat source module reduces the risk of spring force attenuation caused by the high-temperature environment.
[0012] In the above scheme, if the separation interface between the high-temperature heat source module and the heat-conducting cylinder adopts a parallel straight wall structure, there will be continuous sliding friction and surface contact between the side walls during the initial stroke of vertical demolding. This physical phenomenon causes a time delay in the heat conduction cut-off action of the system in the initial stage of separation, which restricts the initial cooling rate of entering the exhaust cooling stage.
[0013] A further improvement of the technical solution of the present invention is that: the lower main body of the high temperature heat source module is in the shape of an inverted frustum, and the upper inner cavity of the heat conduction cylinder is a conical concave cavity adapted to the shape of the inverted frustum.
[0014] By adopting the above technical solution, the lower body of the high-temperature heat source module is configured as an inverted frustum and adapted to the conical cavity of the heat-conducting cylinder. At the moment the demolding stroke begins, the two can achieve full separation of the side wall interface by a slight displacement in the vertical direction. This geometric design eliminates the continuous sliding friction and residual heat conduction of the parallel straight wall structure during the separation process, shortens the physical formation time of the broken bridge gap, directly blocks the heat input, and further improves the cooling rate of the hot pressing system during the cooling stage.
[0015] In scenarios designed for high-speed continuous production, if only a passive clutch structure is used, the heat transfer module only begins to contact the heat source for heat conduction after the workpiece is pressed and subjected to a reaction force. This passive heat conduction mode results in a large proportion of the heating and welding time in a single pressing cycle, which limits the overall production cycle frequency of the equipment to the physical heat conduction time.
[0016] A further improvement of the technical solution of the present invention is that: the clutch action component also includes an electromagnet fixedly installed at the center of the bottom of the lifting frame, and an armature is fixedly connected to the top of the slide plate, and the armature and the electromagnet are used in conjunction.
[0017] By adopting the above technical solution, and by introducing the active attraction and cooperation of electromagnet and armature, in the suspended standby stage after demolding and before contact with the next workpiece, the heat transfer module is forced upward to contact the high-temperature heat source module in advance by electromagnetic force, and enters the pre-heat storage state. This architecture places the solid heat conduction step before the mechanical pressing step, so that the heat transfer module can output the peak welding temperature at the moment of contact with the workpiece, shortening the heat conduction waiting time after contact with the workpiece, and meeting the process requirements of rapid heating in high-speed production scenarios. At the same time, the first spring in the solution plays a mechanical buffering role at the moment of electromagnetic attraction and pressing, reducing the rigid impact force.
[0018] The direct physical bonding of rigid metal interfaces results in microscopic unevenness, which increases the thermal resistance of the interface and limits the heat conduction rate; moreover, long-term rigid contact action is prone to mechanical wear of the bonding interface.
[0019] A further improvement of the technical solution of the present invention is that a flexible block is fixedly connected to the bottom surface of the high-temperature heat source module; the flexible block is a porous mesh structure woven from alloy microwires.
[0020] By employing the above technical solution, a flexible block woven from alloy microwires is placed on the bottom surface of the high-temperature heat source module. Under pressure, the flexible block undergoes microscopic compression deformation, filling the microscopic geometric gaps at the heat transfer interface, eliminating the low thermal conductivity air layer between the contact surfaces, reducing solid-state contact thermal resistance, and improving the heat transfer rate. Simultaneously, its mesh-like structure absorbs longitudinal kinetic energy during compression, reducing the peak impact force during metal-to-metal contact.
[0021] A further improvement of the technical solution of the present invention is that: the bottom wall of the heat-conducting cylinder is provided with a sealed cavity; multiple reinforcing columns are fixedly connected in the vertical direction inside the sealed cavity; the inner wall of the sealed cavity and the outer surface of the reinforcing columns are provided with capillary microstructures, and the sealed cavity is encapsulated with a phase change working fluid.
[0022] By employing the above technical solution, a phase change working fluid and capillary microstructure are set in a sealed cavity. The phase change cycle of the working fluid during the heat absorption vaporization and condensation release processes transforms traditional solid phonon heat conduction into fluid phase change heat transfer, eliminating the heat transfer time lag in the thickness direction and achieving extremely rapid temperature uniformity and heating response at the heat transfer interface. The array of reinforcing columns, while ensuring that the heat transfer module can withstand high-frequency heavy-load impact without structural collapse, directly reduces the solid metal volume of the heat conduction cylinder, significantly reducing the total heat capacity that the system needs to dissipate. Combined with the physical bridging of the clutch action component and the central exhaust mechanism, the cooling rate of the hot-pressing module during the demolding stage is further improved.
[0023] A further improvement of the technical solution of the present invention is that: a plurality of sliding rods are slidably provided in the central part of the bottom of the heat-conducting cylinder, the top of each of the plurality of sliding rods is fixedly connected to a limit end, and a pressure block is fixedly connected between the bottoms, and a second spring is sleeved on the outside of the plurality of sliding rods and located between the heat-conducting cylinder and the pressure block.
[0024] By adopting the above technical solution, and by setting a sliding rod, a pressure block, and a second spring through the bottom of the heat-conducting cylinder, the pressure block contacts the workpiece before the hot-pressing module and applies a pre-compression force to it during the downward pressing stroke, thus achieving mechanical positioning of the material before heat sealing. During the upward demolding stroke, the elastic potential energy released by the second spring causes the pressure block to detach from the workpiece with a delay. This delayed detachment action forces the high-temperature viscous polymer material to be physically separated from the surface of the hot-pressing module, avoiding adhesion or stringing caused by the packaging material being lifted synchronously with the mold, and improving the geometric flatness of the heat-sealed opening after cooling and shaping.
[0025] A further improvement of the technical solution of the present invention is that: the hot pressing module is a prefabricated component that can be independently replaced; the hot pressing module includes a mounting plate and a hot pressing plate fixedly connected to the bottom surface of the mounting plate; the bottom surface of the heat-conducting cylinder is provided with mounting holes; in hot pressing modules of different geometric specifications, the mounting plate is provided with mating holes whose positions are adapted to the mounting holes, and the mounting plate is detachably fixedly connected to the bottom surface of the heat-conducting cylinder by fasteners passing through the mating holes, and the mounting holes are blind holes.
[0026] By adopting the above technical solution, the hot pressing module that directly contacts the workpiece is designed as an independent prefabricated component including a mounting plate and a hot pressing plate. It is then physically connected to the heat transfer module above using standardized mounting holes. This achieves modularization of mold changeover. When dealing with packaged workpieces of different shapes and sizes, only the bottom hot pressing module needs to be replaced as a whole, without having to replace the expensive heat transfer module and high-temperature heat source module. The uniform hole arrangement ensures that hot pressing plates of different geometric specifications can be accurately connected to the equipment body, reducing the mold opening cost for multi-specification product production and shortening the downtime for production line changeover.
[0027] The present invention also provides an intelligent hot pressing molding method, comprising the following steps: S1. Coordinate positioning: Control the mounting bracket to slide horizontally along the gantry, so that the hot pressing execution system reaches the predetermined processing position; S2, Pressing and Heat Transfer Welding: The driving lifting assembly causes the lifting frame to perform the pressing stroke downwards, and the hot pressing module abuts against the target workpiece; the clutch action assembly causes the bottom surface of the high temperature heat source module and the inner cavity of the heat transfer module to enter a physical contact state, and heat is input to the surface of the workpiece by solid heat conduction to complete the welding. S3, Broken Bridge Separation and Pressure Holding Exhaust: The driving lifting component causes the lifting frame to perform the initial displacement of the demolding stroke. The clutch action component forces the high-temperature heat source module and the heat transfer module to physically separate and form a broken bridge gap. At the same time, the heat transfer module maintains the physical pressing state on the workpiece. The external fan draws negative pressure through the central exhaust channel and guides the external cold air to flow through the broken bridge gap to remove the residual heat of the heat transfer module and cool down and shape the workpiece. S4. Demolding: After the workpiece cools down to the set demolding temperature, the lifting frame continues to move upward to perform the demolding stroke, driving the heat transfer module and the hot pressing module to move upward as a whole, completely separating from the target workpiece.
[0028] In the welding process of step S2, the physical continuity of the heat conduction path is ensured, making the response time of the heating process shorter than that of indirect radiation heating. In the cooling process of step S3, by utilizing the passive or active separation of the mechanical structure, the heat input of the high-temperature heat source is forcibly cut off while the workpiece is still under pressure constraint, and forced centripetal negative pressure exhaust is simultaneously introduced. This process cuts off the path of continuous penetration of the high-temperature heat source to the cooling end, unloads the heat capacity burden of the redundant metal entity, and makes the total time of a single hot pressing forming cycle shorter than that of the traditional integrated constant temperature hot pressing process, thereby improving the high-frequency continuous operation capability of the production line.
[0029] By adopting the above technical solution, the technical effects achieved by this invention compared to the prior art are as follows: 1. This invention provides an intelligent hot pressing molding equipment and method. By setting a clutch action component, during the pressing stroke, the high-temperature heat source module and the heat transfer module maintain physical contact, and heat is conducted through direct contact between the objects. During the demolding stroke, the two are physically separated and form a broken bridge gap, cutting off the heat input of the heat source from the physical conduction path. The central exhaust channel opened inside the support column is connected to the broken bridge gap, and the external fan draws in a centripetal negative pressure airflow to forcibly remove the heat trapped in the gap, thereby improving the heat dissipation rate of the inner wall of the heat conduction cylinder and shortening the cooling and shaping time of the workpiece, thus overcoming the contradiction between large heat capacity and rapid cooling.
[0030] 2. This invention provides an intelligent hot pressing molding equipment and method. By setting a first spring sleeved outside the guide rod and a support column passing through the through hole of the high-temperature heat source module and connecting to the slide plate, a purely mechanical passive engagement and disengagement between the high-temperature heat source module and the heat transfer module is achieved. This scheme utilizes the reaction force generated by the workpiece when pressing downward to compress the first spring to achieve physical bonding between the modules, and utilizes the potential energy released by the first spring when demolding upward to achieve physical separation between the modules. This eliminates the need for an additional clutch drive source and simplifies the control logic of the equipment. At the same time, placing the first spring and the slide plate above the high-temperature heat source module reduces the risk of spring force attenuation caused by the high-temperature environment.
[0031] 3. This invention provides an intelligent hot pressing molding equipment and method. By configuring the lower main body of the high-temperature heat source module into an inverted frustum shape and adapting it to the conical cavity of the heat-conducting cylinder, the two can achieve full separation of the side wall interface by a slight displacement in the vertical direction at the moment the demolding stroke begins. This geometric design eliminates the continuous sliding friction and residual heat conduction of the parallel straight wall structure during the separation process, shortens the physical formation time of the broken bridge gap, directly blocks the heat input, and further improves the cooling rate of the hot pressing system during the cooling stage.
[0032] 4. This invention provides an intelligent hot pressing molding equipment and method. By introducing the active adsorption and cooperation of electromagnet and armature, in the suspended standby stage after demolding and before contact with the next workpiece, electromagnetic force forces the heat transfer module upward to pre-fit with the high-temperature heat source module, entering a pre-heat storage state. This architecture places the solid heat conduction step before the mechanical pressing step, so that the heat transfer module can output the peak welding temperature at the moment of contact with the workpiece, shortening the heat conduction waiting time after contact with the workpiece, and meeting the process requirements of rapid heating in high-speed production scenarios. At the same time, the first spring in the solution plays a mechanical buffering role at the moment of electromagnetic adsorption and pressing, reducing the rigid impact force.
[0033] 5. This invention provides an intelligent hot pressing molding equipment and method. By setting a phase change working fluid and capillary microstructure in a sealed cavity, and utilizing the phase change cycle of the working fluid during the heat absorption vaporization and condensation release processes, the traditional solid phonon heat conduction is transformed into fluid phase change heat transfer. This eliminates the heat transfer time lag in the thickness direction and achieves extremely rapid temperature uniformity and heating response at the heat transfer interface. The arrayed reinforcing columns, while ensuring that the heat transfer module can withstand high-frequency heavy-load impact without structural collapse, directly reduce the solid metal volume of the heat conduction cylinder, significantly reducing the total heat capacity that the system needs to dissipate. Combined with the physical bridging of the clutch action component and the central exhaust mechanism, the cooling rate of the hot pressing module during the demolding stage is further improved.

[0037] The present invention will be further described in detail below with reference to the embodiments.
[0038] Example 1 like Figures 1-9As shown, this invention provides an intelligent hot pressing molding equipment, including a gantry frame 1 and a mounting frame 2 that can slide horizontally along the gantry frame 1; it also includes: a lifting frame 4; a lifting assembly 3, mounted on the mounting frame 2, with its movable end fixedly connected to the lifting frame 4, used to control the lifting frame 4 to rise and fall vertically; a hot pressing execution system 6, mounted on the lifting frame 4, comprising, from top to bottom, a high-temperature heat source module 610, a heat transfer module 620, and a hot pressing module 630; the heat transfer module 620 includes a heat conducting cylinder 621, and the hot pressing module 630 is connected to the bottom surface of the heat conducting cylinder 621; a support column 623 is fixedly connected to the center of the inner cavity of the heat conducting cylinder 621; a central exhaust channel is opened in the support column 623 of the heat transfer module 620, and the central... The upper end of the exhaust duct is connected to a fan independently installed outside the equipment via a pipe; the clutch actuation component 5 is located between the high-temperature heat source module 610 and the heat transfer module 620; the clutch actuation component 5 is used to drive the high-temperature heat source module 610 to move relative to the heat transfer module 620, and it is configured such that: when the lifting frame 4 performs a downward pressing stroke, the clutch actuation component 5 causes the bottom surface of the high-temperature heat source module 610 to enter a physical fit with the inner cavity of the heat transfer module 620; when the lifting frame 4 performs an upward demolding stroke, the clutch actuation component 5 forces the high-temperature heat source module 610 and the heat transfer module 620 to physically separate, so as to form a broken bridge gap between the two; the broken bridge gap is connected to the lower opening of the central exhaust duct.
[0039] In this embodiment, by setting the clutch action component 5, during the pressing stroke, the high temperature heat source module 610 and the heat transfer module 620 remain physically attached, and heat is conducted through direct contact between the objects; while during the demolding stroke, the two are physically separated and form a broken bridge gap, cutting off the heat input of the heat source from the physical conduction path, so that during the cooling and shaping stage, the equivalent metal heat capacity participating in heat dissipation is less than the total heat capacity of the traditional one-piece mold.
[0040] Furthermore, by utilizing the central exhaust channel located inside the support column 623 and connecting it to the gap of the broken bridge, an external fan draws in and generates a centripetal negative pressure airflow, forcibly removing the heat trapped in the gap, thereby improving the heat dissipation rate of the back of the heat transfer module 620 and shortening the cooling and shaping time of the workpiece, thus overcoming the contradiction between large heat capacity and rapid cooling.
[0041] Its specific working principle is as follows: When the equipment is performing coordinate positioning, the mounting frame 2 slides horizontally along the gantry frame 1 to reach the predetermined work position. Subsequently, the lifting assembly 3 drives the lifting frame 4 to make a downward pressing stroke in the vertical direction to provide the mechanical stamping force required for heat sealing. During the hot-pressing welding process, as the lifting frame 4 descends, the clutch actuation component 5 drives the bottom surface of the high-temperature heat source module 610 to physically adhere to the inner cavity of the heat transfer module 620. At this time, the constant heat inside the high-temperature heat source module 610 is conducted downwards through the heat transfer module 620 and transferred to the bottom hot-pressing module 630 via solid-state contact conduction, causing the surface temperature of the contacting workpiece to reach the melting point of the polymer material. This physical adhesion state ensures low thermal resistance in the heat transfer path and improves the heating response speed. When the welding process is completed and the cooling and shaping process begins, the lifting frame 4 performs an upward demolding stroke. During this process, the clutch actuation component 5 forces the high-temperature heat source module 610 to move upward relative to the heat transfer module 620, achieving physical separation between the two and forming a broken bridge gap at the original contact interface. The working principle of this separation action is that by increasing the physical distance, the heat conduction from the high-temperature heat source to the solid below is directly blocked. In this state, the heat transfer module 620 and the hot pressing module 630, which remain below and continue to exert physical constraints on the workpiece, avoid continuous heat input, effectively reducing the total heat capacity of the system during the cooling stage and "unloading" unnecessary cooling burden.
[0042] Simultaneously with the formation of the broken bridge gap, the central exhaust channel located inside the support column 623 begins operation. Since the lower opening of this channel is connected to the broken bridge gap, an externally mounted fan generates aerodynamic negative pressure within the central exhaust channel via pipes. Ambient cold air rushes in laterally from the periphery of the broken bridge gap, carrying away residual heat from the metal as it flows through the inner cavity of the heat transfer module 620, transforming it into hot air. This hot air, under negative pressure suction, forms a centripetal converging flow field and is ultimately forcibly drawn into the support column 623 and discharged to the outside of the equipment. This process utilizes a forced convection mechanism to maintain a high rate of heat loss from the inner wall of the heat-conducting cylinder 621, improving the overall cooling rate of the mold and meeting the objective process requirement for rapid cooling under high-frequency production cycles.
[0043] The high-temperature heat source module 610 includes a heat source main block and heating elements embedded within the heat source main block. Preferably, the heat source main block is made of a rigid metal material with high thermal conductivity (such as aluminum alloy or pure copper); the heating elements are multiple arrayed heating rods or heating tubes. In operation, an external temperature control system continuously supplies power to the heating rods, converting electrical energy into heat energy and storing it in the heat source main block to maintain a constant high temperature as set by the process. This module acts as a continuous and stable basic heat energy output source in the equipment. The hot pressing module 630 is fixedly connected to the bottom surface of the heat transfer module 620 and acts as the end effector for directly pressing the target workpiece. The bottom surface of the hot pressing module 630 is machined with a heat-sealing working surface that matches the packaging trajectory of the target workpiece. During the pressing action, the module receives the transient heat conducted downward by the heat transfer module 620 and applies specific physical static pressure and heat energy to the surface of the polymer material simultaneously, so that the material reaches the viscous flow melting point to achieve local melting and bonding.
[0044] Example 2 like Figure 2 , Figure 3 and Figure 4 As shown, based on Embodiment 1, the present invention provides a technical solution: Preferably, the clutch action assembly 5 includes at least two guide rods 501 fixed to the lifting frame 4 and extending vertically downward, and a first spring 502 sleeved on the outside of the guide rods 501; the bottom of each guide rod 501 is fixedly connected to an isolation column 503; a high-temperature heat source module 610 is fixed between the bottoms of the isolation columns 503, and a through hole extending axially is opened at the axial center position of the high-temperature heat source module 610; a sliding plate 624 is fixedly connected to the top of the support column 623, and the sliding plate 624 has a sliding hole adapted to the guide rod 501, and the sliding plate 624 is slidably sleeved on the guide rod 501 through the sliding hole; the upper end of the first spring 502 abuts against the lifting frame 4, and its lower end abuts against the sliding plate 624.
[0045] In this embodiment, by setting a first spring 502 sleeved on the outside of the guide rod 501 and a support column 623 passing through the through hole of the high-temperature heat source module 610 and connecting to the slide plate 624, a purely mechanical passive engagement and disengagement between the high-temperature heat source module 610 and the heat transfer module 620 is realized. This scheme uses the reaction force generated by the workpiece when pressing downward to compress the first spring 502 to achieve physical contact between the modules, and uses the potential energy released by the first spring 502 when demolding upward to achieve physical separation between the modules, eliminating the need for an additional clutch drive source and simplifying the control logic of the equipment; at the same time, placing the first spring 502 and the slide plate 624 above the high-temperature heat source module 610 reduces the risk of elasticity attenuation of the first spring 502 caused by the high-temperature environment.
[0046] During the downward pressing stroke, the lifting frame 4 drives the entire assembly to move down synchronously. When the bottom hot pressing module 630 abuts against the target workpiece and is subjected to a reaction force, the slide plate 624, together with the support column 623 and the heat conduction cylinder 621, remains stationary in the longitudinal direction. At this time, the lifting frame 4 continues to move down against the thrust of the first spring 502, thereby driving the high-temperature heat source module 610 to move down along the guide rod 501 until the bottom surface of the high-temperature heat source module 610 is tightly fitted with the inner cavity of the heat conduction cylinder 621, completing the heat conduction path. At this moment of contact, the compression stroke of the first spring 502 absorbs some kinetic energy, reducing the mechanical impact force generated by rigid contact.
[0047] During the upward demolding stroke, the lifting frame 4 is lifted upward, the reaction force applied to the target workpiece disappears, the first spring 502 in the compressed state releases potential energy, and pushes the sliding plate 624 downward, forcing the heat transfer module 620 to quickly separate from the high-temperature heat source module 610, thereby forming the broken bridge gap required for exhaust heat dissipation. As the heat transfer module 620 moves downward relative to the plate until the sliding plate 624 abuts against the top of the isolation column 503, the isolation column 503 completes the mechanical limit of the maximum separation gap. This passive execution logic realizes the automatic bonding and separation of the heat source and heat transfer components under specific processes, improving the operational reliability of the mechanical system.
[0048] like Figure 4 , Figure 5 and Figure 6 As shown, preferably, the lower body of the high-temperature heat source module 610 is in the shape of an inverted frustum, and the upper inner cavity of the heat-conducting cylinder 621 is a conical cavity adapted to the shape of the inverted frustum.
[0049] In this embodiment, by configuring the lower body of the high-temperature heat source module 610 into an inverted frustum shape and adapting it to the conical cavity of the heat-conducting cylinder 621, the two can achieve full separation of the sidewall interface by a slight displacement in the vertical direction at the moment the demolding stroke begins. This geometric design eliminates the continuous sliding friction and residual heat conduction of the parallel straight wall structure during the separation process, shortens the physical formation time of the broken bridge gap, directly blocks the heat input, and further improves the cooling rate of the hot pressing system during the cooling stage.
[0050] When in a physically bonded state, the high-temperature heat source module 610 moves downward, and the inverted frustum-shaped inclined sidewall comes into close contact with the inner wall of the conical cavity. This conical contact structure increases the solid heat conduction area between the heating element and the heat transfer element, improving the efficiency of heat transfer downward. On the other hand, the inclined guiding characteristics of the conical surface play a mechanical self-centering role during the downward pressing process, ensuring the precise radial alignment of the upper and lower modules.
[0051] When in a physically separated state, that is, at the initial moment when the clutch action component 5 forces the two to separate vertically relative to each other, based on the geometric and physical characteristics of the inverted frustum, the side wall and the inner wall simultaneously disengage along the entire line. This action mechanism allows the device to generate a physical gap in the normal direction of the contact interface with only a very small vertical Z-axis displacement. This structure completely eliminates the long-distance contact sliding and continuous heat conduction of the straight cylindrical side wall in the early stage of the separation stroke, ensuring that the heat penetration of the high-temperature heat source downward is cut off instantly.
[0052] Meanwhile, the annular space released between the separated sidewall and inner wall directly constitutes the main part of the broken bridge gap. This expanded space provides a wide and smooth fluid channel for the subsequent central exhaust duct to draw in external cold air, reducing airflow resistance and improving the flow rate and convective heat transfer efficiency of cold air in the broken bridge gap.
[0053] Example 3 like Figure 4 , Figure 5 and Figure 6 As shown, based on Embodiment 2, the present invention provides a technical solution: preferably, the clutch action component 5 further includes an electromagnet 511 fixedly installed at the center of the bottom of the lifting frame 4, and an armature 512 fixedly connected to the top of the slide plate 624, the armature 512 and the electromagnet 511 working together.
[0054] In this embodiment, by introducing the active attraction and cooperation between the electromagnet 511 and the armature 512, during the suspended standby stage after demolding and before contact with the next workpiece, the heat transfer module 620 is forced upward to contact the high-temperature heat source module 610 in advance by electromagnetic force, entering a pre-heat storage state. This architecture places the solid heat conduction step before the mechanical pressing step, so that the heat transfer module 620 can output the peak welding temperature at the moment of contact with the workpiece, shortening the heat conduction waiting time after contact with the workpiece, and meeting the process requirements of rapid heating in high-speed production scenarios. At the same time, the first spring 502 in the solution plays a mechanical buffering role at the moment of electromagnetic attraction and pressing, reducing the rigid impact force.
[0055] The rated electromagnetic attraction force of the electromagnet 511 is set to be greater than the sum of the current compression force of the first spring 502, the slide plate 624, the support column 623, and the overall weight of the heat transfer module 620.
[0056] During the suspension and standby phase after the demolding process is completed, the control system energizes the electromagnet 511, which generates an electromagnetic attraction force, attracting the armature 512 below to move upward. This action drives the slide plate 624 and the support column 623 to overcome the downward pushing force of the first spring 502, forcing the inner cavity of the heat conduction cylinder 621 to move upward until it enters a physical contact state with the high-temperature heat source module 610 in advance. At this time, the broken bridge gap closes, and the heat from the heat source begins to be conducted to the heat transfer module 620 in a solid state, completing the preheating. During the downward pressing stroke, the lifting frame 4 drives the already bonded components to move down synchronously. Since the first spring 502 has been compressed in advance by the electromagnetic force, when the bottom hot pressing module 630 contacts the target workpiece, the compressed first spring 502 releases some elastic potential energy, absorbs the mechanical impact force in the vertical direction, and plays the role of mechanical damping buffer. After contacting the workpiece, the control system cuts off the power supply to the electromagnet 511. At this time, the physical reaction force generated by the target workpiece seamlessly takes over and maintains the compressed state of the first spring 502, ensuring that the high temperature heat source module 610 and the heat transfer module 620 continue to bond during the welding process.
[0057] During the subsequent demolding process, the electromagnet 511 remains de-energized, and the first spring 502 releases potential energy according to pure mechanical physical logic, which once again pushes the heat transfer module 620 to separate from the high-temperature heat source module 610, restoring the exhaust cooling channel.
[0058] like Figure 1-5 As shown, in this embodiment, preferably, a flexible block 611 is fixedly connected to the bottom surface of the high-temperature heat source module 610; the flexible block 611 is a porous mesh structure woven from alloy microwires.
[0059] In this embodiment, a flexible block 611 made of alloy microfilament braid is provided on the bottom surface of the high-temperature heat source module 610. Under pressure, the flexible block 611 undergoes microscopic compression deformation, filling the microscopic geometric gaps at the heat transfer interface, eliminating the low thermal conductivity air layer between the contact surfaces, reducing the solid contact thermal resistance, and improving the heat transfer rate. At the same time, its mesh-like shape absorbs longitudinal kinetic energy at the moment of compression, reducing the peak impact force during metal contact.
[0060] The flexible block 611 is preferably a porous mesh structure made of beryllium copper alloy microwires.
[0061] During the downward pressing stroke, the flexible block 611 is pressed down along with the high-temperature heat source module 610 and comes into contact with the inner cavity of the heat-conducting cylinder 621. Under the action of pressing static force, the flexible block 611 undergoes elastic compression, and its mesh metal microfilaments undergo physical displacement and closely adhere to the micro-contour of the inner cavity of the heat-conducting cylinder 621. This extrusion action squeezes out the residual air between the interfaces, constructing a high-density metal heat conduction path, which allows the heat from the heat source to penetrate into the heat-conducting cylinder 621 at an extremely fast speed. During the upward demolding stroke, as the clutch action component 5 forces the two modules to separate, the flexible block 611 is lifted upward synchronously with the high-temperature heat source module 610. This separation action completely removes the porous flexible block 611 with high infrared absorption rate and high fluid resistance from the broken bridge gap, making the inner cavity of the heat conduction cylinder 621 appear as a bare, smooth metal.
[0062] Example 4 like Figure 5 , Figure 6 and Figure 9 As shown, based on Embodiment 3, the present invention provides a technical solution: preferably, the bottom wall of the heat-conducting cylinder 621 is provided with a sealed cavity 626; a plurality of reinforcing columns 622 are fixedly connected in the vertical direction inside the sealed cavity 626; the inner wall of the sealed cavity 626 and the outer surface of the reinforcing columns 622 are provided with capillary microstructures 625, and the sealed cavity 626 is encapsulated with a phase change working fluid.
[0063] In this embodiment, since the heat transfer module 620 needs to frequently increase and decrease temperature, in order to improve its response speed, a phase change working fluid and capillary microstructure 625 are set in the sealed cavity 626. The phase change cycle of the working fluid during the heat absorption vaporization and condensation heat release process is used to transform the traditional solid phonon heat conduction into fluid phase change heat transfer, eliminating the heat transfer time lag in the thickness direction and realizing extremely rapid temperature uniformity and heating response of the heat transfer interface. The array of reinforcing columns 622, while ensuring that the heat transfer module 620 can withstand high-frequency heavy-load impact without structural collapse, directly reduces the solid metal volume of the heat conduction cylinder 621, which greatly reduces the total heat capacity that the system needs to dissipate. Combined with the physical bridging and central exhaust mechanism of the clutch action component 5, the cooling rate of the hot pressing module 630 during the demolding stage is further improved.
[0064] In the static assembly structure, the bottom wall of the heat-conducting cylinder 621 is hollowed out and sealed to form a closed cavity 626. To resist the enormous mechanical impact force generated by the downward movement of the thermo-pressurizing system 6, multiple reinforcing columns 622 extending vertically are arrayed within the closed cavity 626. The upper ends of the reinforcing columns 622 are rigidly connected to the top inner wall of the closed cavity 626, and the lower ends are rigidly connected to the bottom inner wall of the closed cavity 626. The inner wall of the closed cavity 626 and the outer surfaces of all the reinforcing columns 622 are sintered or coated with capillary microstructures 625 composed of metal powder or mesh. The closed cavity 626 is in a high vacuum state and is encapsulated with an appropriate amount of phase change working fluid (such as deionized water).
[0065] During the downward pressing stroke (heating step), when the high-temperature heat source module 610 and the heat transfer module 620 are bonded together, the top inner wall of the sealed cavity 626 is heated and becomes the evaporation end. The liquid phase change working fluid that is in close contact with the top inner wall absorbs heat and undergoes violent boiling, transforming into high-temperature and high-pressure steam. Driven by the pressure gradient, the steam rushes downward at high speed along the channel between the reinforcing columns 622, reaches the lower temperature bottom inner wall (condensation end) and condenses into liquid, instantly releasing a large amount of latent heat of vaporization, causing the temperature of the bottom hot pressing module 630 to rise rapidly to the welding set value. The condensed liquid flows back to the top inner wall against gravity under the capillary suction force generated by the capillary microstructure 625, maintaining the phase change cycle.
[0066] During the upward demolding stroke (cooling step), when the two modules separate and the central exhaust channel draws in external cold air, the thermodynamic boundary of the system reverses. The temperature of the top inner wall of the sealed cavity 626 drops sharply due to the blowing of cold air, turning into a condensation end; while the bottom inner wall absorbs the residual heat of the workpiece, turning into an evaporation end. The working fluid at the bottom absorbs the heat of the workpiece, vaporizes and is flushed upward. After condensing on the top inner wall, the heat is carried away by the external airflow. This reverse heat extraction process directly removes the residual heat in the contact area with the workpiece, improving the overall cooling rate of the mold.
[0067] like Figure 5 , Figure 6 and Figure 9 As shown, preferably, a plurality of slide rods 701 are slidably provided in the central part of the bottom of the heat-conducting cylinder 621. The top ends of the plurality of slide rods 701 are fixedly connected to limit ends 702, and the bottoms are fixedly connected to pressure blocks 704. A second spring 703 is sleeved on the outside of the plurality of slide rods 701 and between the heat-conducting cylinder 621 and the pressure blocks 704.
[0068] In this embodiment, by setting a slide rod 701, a pressure block 704, and a second spring 703 passing through the bottom of the heat-conducting cylinder 621, during the downward pressing stroke, the pressure block 704 contacts the workpiece before the hot pressing module 630 and applies a pre-clamping force to it, thus achieving mechanical positioning of the material before heat sealing; during the upward demolding stroke, the elastic potential energy released by the second spring 703 causes the pressure block 704 to detach from the workpiece with a delay; this delayed detachment action forces the high-temperature viscous polymer material to be physically separated from the surface of the hot pressing module 630, avoiding adhesion or stringing caused by the packaging material being lifted synchronously with the mold, and improving the geometric flatness of the heat-sealed opening after cooling and shaping.
[0069] In its naturally extended state, the second spring 703 pushes the pressure block 704 downward, causing the limiting end 702 to abut against the inner bottom surface of the heat-conducting cylinder 621. At this time, the bottom surface of the pressure block 704 is lower than the bottom surface of the hot-pressing module 630 in vertical height.
[0070] During the downward pressing stroke, as the lifting frame 4 descends, the bottom surface of the pressing block 704 is lower than the hot pressing module 630, so the pressing block 704 contacts the target workpiece before the hot pressing module 630. After the pressing block 704 contacts the workpiece, it stops moving downward. The lifting frame 4 drives the heat-conducting cylinder 621 and the hot pressing module 630 to continue pressing downward, causing the second spring 703 to be compressed and accumulate elastic potential energy. At this time, the pressing block 704 firmly presses the workpiece onto the worktable under the thrust of the second spring 703, preventing the polymer material from thermally shrinking and shifting during subsequent heating. Then, the hot pressing module 630 contacts the surface of the workpiece and performs welding.
[0071] During the upward demolding stroke, when the welding and cooling are completed, the lifting frame 4 drives the heat-conducting cylinder 621 and the hot-pressing module 630 to lift upward. In the initial stage of lifting, the second spring 703, which is in a compressed state, releases its elastic potential energy and continues to push the pressure block 704 downward. At this time, the hot-pressing module 630 has already detached from the workpiece surface, while the pressure block 704 still maintains a pressing state on the workpiece. By using the physical obstruction of the pressure block 704, the adhesion between the bottom surface of the hot-pressing module 630 and the molten workpiece is forcibly cut off, achieving complete mechanical peeling. As the heat-conducting cylinder 621 continues to move upward until its inner bottom surface abuts against the limiting end 702 at the top of the slide rod 701, the pressure block 704 follows the heat transfer module 620 and is lifted upward as a whole and finally detaches from the workpiece.
[0072] Example 5 like Figure 5 , Figure 6 and Figure 8 As shown, based on Embodiment 4, the present invention provides a technical solution: preferably, the hot pressing module 630 is a prefabricated component that can be independently replaced; the hot pressing module 630 includes a mounting plate 631 and a hot pressing plate 632 fixedly connected to the bottom surface of the mounting plate 631; the bottom surface of the heat-conducting cylinder 621 is provided with mounting holes; in hot pressing modules 630 of different geometric specifications, the mounting plate 631 is provided with mating holes whose positions are adapted to the mounting holes, and the mounting plate 631 is detachably fixedly connected to the bottom surface of the heat-conducting cylinder 621 by fasteners passing through the mating holes, and the mounting holes are blind holes.
[0073] In this embodiment, by designing the hot pressing module 630, which directly contacts the workpiece, as an independent prefabricated component including a mounting plate 631 and a hot pressing plate 632, and using standardized mounting holes to physically connect it with the upper heat transfer module 620, modularization of mold changeover is achieved. When dealing with packaged workpieces of different shapes and sizes, only the bottom hot pressing module 630 needs to be replaced as a whole, without replacing the expensive heat transfer module 620 and high-temperature heat source module 610. The uniform hole arrangement ensures that the hot pressing plate 632 of different geometric specifications can be accurately docked with the equipment body, reducing the mold opening cost for multi-specification product production and shortening the downtime of production line changeover.
[0074] Specifically, the prefabricated component includes an upper mounting plate 631 and a hot press plate 632 rigidly fixed to the bottom surface of the mounting plate 631. The bottom surface of the hot press plate 632 is machined with raised textures or working surfaces that match the heat sealing trajectory of a specific target workpiece. To achieve universal assembly, in different batches of hot press modules 630, the top surface of the mounting plate 631 is machined into a flat heat-conducting contact surface, and the mounting plate 631 is provided with mating holes (such as countersunk through holes) corresponding to the mounting holes on the bottom surface of the heat transfer module 620.
[0075] The present invention also provides an intelligent hot pressing molding method, comprising the following steps: S1. Coordinate positioning: Control the mounting bracket 2 to slide horizontally along the gantry 1, so that the hot pressing execution system 6 reaches the predetermined processing position; S2, Pressing and heat conduction welding: Drive the lifting assembly 3 to make the lifting frame 4 perform the pressing stroke downward, and the hot pressing module 630 abuts against the target workpiece; the clutch action assembly 5 makes the bottom surface of the high temperature heat source module 610 and the inner cavity of the heat transfer module 620 enter a physical bonding state, and input heat to the surface of the workpiece by solid heat conduction to complete the welding. S3, Bridge Break Separation and Pressure Holding Exhaust: The driving lifting assembly 3 causes the lifting frame 4 to perform the initial displacement of the demolding stroke. The clutch action assembly 5 forces the high-temperature heat source module 610 and the heat transfer module 620 to physically separate and form a bridge break gap. At the same time, the heat transfer module 620 maintains a physical pressing state on the workpiece. The external fan draws negative pressure through the central exhaust channel and guides the external cold air to flow through the bridge break gap to remove the residual heat of the heat transfer module 620 and cool and shape the workpiece. S4. Demolding: After the workpiece cools down to the set demolding temperature, the lifting frame 4 continues to perform the demolding stroke, driving the heat transfer module 620 and the hot pressing module 630 to move upward as a whole, completely separating from the target workpiece.
[0076] In the welding process of step S2, the physical continuity of the heat conduction path is ensured, making the response time of the heating process shorter than that of indirect radiation heating. In the cooling process of step S3, by utilizing the passive or active separation of the mechanical structure, the heat input of the high-temperature heat source is forcibly cut off while the workpiece is still under pressure constraint, and forced centripetal negative pressure exhaust is simultaneously introduced. This process cuts off the path of continuous penetration of the high-temperature heat source to the cooling end, unloads the heat capacity burden of the redundant metal entity, and makes the total time of a single hot pressing forming cycle shorter than that of the traditional integrated constant temperature hot pressing process, thereby improving the high-frequency continuous operation capability of the production line.
[0077] In step S1, the system receives the coordinates from the process drawing and uses the servo motor to drive the mounting bracket 2 to complete the absolute coordinate positioning of the XY horizontal plane on the gantry 1, so that the entire hot pressing execution system 6 is precisely aligned above the target workpiece to be processed.
[0078] Optionally, between steps S1 and S2, a pre-heat storage step is included: the electromagnet 511 is energized to generate electromagnetic attraction, which overcomes the pushing force of the first spring 502, causing the heat transfer module 620 to be attracted upwards and pre-fitted with the high-temperature heat source module 610. This action ensures that the heat transfer module 620 reaches the preset welding temperature before contacting the workpiece.
[0079] In step S2, a downward pressing stroke along the Z-axis is executed. The hot pressing module 630 first contacts the surface of the target workpiece. As the lifting frame 4 continues to descend, the clutch actuation component 5 actuates, and the high-temperature heat source module 610 presses down and physically adheres to the heat transfer module 620. The constant heat energy inside the high-temperature heat source module 610 is instantly transferred downwards, passing through the heat transfer module 620 and the hot pressing plate 632, causing the sealing area of the polymer workpiece to reach the viscous flow melting point.
[0080] Optionally, before the hot pressing module 630 contacts the workpiece, the pressure block 704 first contacts the workpiece surface under the thrust of the second spring 703, applying a pre-compression force to the polymer material, thus eliminating the edge curling phenomenon caused by thermal shrinkage.
[0081] In step S3, the welding countdown ends, and the cooling and shaping process begins. The lifting frame 4 performs an initial small displacement upwards during the demolding stroke. This displacement is released by the elastic potential energy of the first spring 502 (or the electromagnet 511 is de-energized), forcing the high-temperature heat source module 610 to rise upwards along with the lifting frame 4, while the heat transfer module 620 continues to maintain static physical pressure on the workpiece under the spring force. At this time, the two modules physically separate, forming a broken bridge gap. Simultaneously, the external fan draws in negative pressure through the central exhaust channel inside the support column 623. The surrounding ambient temperature air is forcibly drawn in from the periphery of the broken bridge gap, flowing towards the central channel along the inner wall of the heat-conducting cylinder 621. During the flow, the airflow undergoes strong convective heat exchange with the mold surface, carrying away residual heat from the metal. This process achieves rapid cooling while maintaining the physical dimensional constraints of the workpiece.
[0082] In step S4, the temperature sensor determines that the temperature of the heat transfer module 620 has dropped to the set safe demolding temperature (e.g., 80°C), and the lifting frame 4 continues to perform a large upward demolding stroke. The isolation column 503 at the bottom of the guide rod 501 pulls the slide plate 624 and the heat transfer module 620 upward, causing them to detach from the workpiece surface as a whole.
[0083] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
