Description

Technical Field

[0001] This utility model relates to the field of laminate technology, specifically a circulating cooling device for thermoplastic laminate molding. Background Technology

[0002] Laminated sheets are a type of laminated product. Laminated products are made by laminating and hot-pressing two or more layers of resin-impregnated fibers or fabrics together.

[0003] Existing methods for cooling laminates during molding include natural cooling and forced cooling. Forced cooling includes water cooling, air cooling, and heat pipe cooling. Water cooling involves a water-cooled plate contacting the hot-pressed laminate to indirectly transfer heat from the heat-generating components to the cooling liquid in the circulation pipe, thereby achieving a cooling effect.

[0004] However, during the hot pressing process of the laminate, the liquid remaining in the water-cooled plate will affect the laminate during the hot pressing process, causing the temperature of the laminate near the water-cooled plate to be lower. This will reduce the adhesion of the bottom layer, thus ultimately affecting the quality of the laminate. Utility Model Content

[0005] The purpose of this invention is to provide a circulating cooling device for thermoplastic laminate molding to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A circulating cooling device for thermoplastic laminate molding includes: a placement plate disposed on a base and a hot press plate slidably disposed on the base. A water-cooling plate is disposed on the placement plate, and a main pipeline and a secondary pipeline are disposed on the water-cooling plate. The main pipeline is used to cool the laminate on the placement plate.

[0008] The main pipeline connects to an external water storage tank and a water pump mounted on the base. The secondary pipeline is connected to the main pipeline via a conversion assembly. The conversion assembly includes a trigger structure and a switching structure. The trigger structure is mounted on the hot press plate and the base. During the hot pressing process as the hot press plate descends, the trigger structure can drive the switching structure to block the main pipeline and the secondary pipeline, so that the water pump first empties the water in the main pipeline and then pumps the water out of the water storage tank through the secondary pipeline, thus enabling the laminate to be formed.

[0009] The circulating cooling device for thermoplastic laminate molding as described above: the main pipeline includes a water-cooled pipe disposed in the water-cooled plate and a ball valve disposed on the base. The water-cooled pipe has a serpentine structure, and one end of the water-cooled pipe is connected to the water pump, and the other end is connected to the main pipe port of the ball valve.

[0010] The circulating cooling device formed by thermoplastic laminate as described above: the secondary pipeline includes a side branch pipeline, one end of which is connected to the outlet of the water cooling pipe, and the other end is connected to the secondary port of the ball valve.

[0011] The circulating cooling device for thermoplastic laminate molding as described above: the triggering structure includes a triggering element and a passive element, the triggering element includes a triggering block disposed on the hot press plate, and the triggering block is provided with a triggering surface.

[0012] The circulating cooling device for thermoplastic laminate molding as described above: the passive component includes a passive block slidably disposed on the base, and the passive block is provided with an abutment surface.

[0013] The circulating cooling device for thermoplastic laminate molding as described above: the switching structure includes a switching component and a driving component. The switching component includes a valve core that is rotatably and sealed on the ball valve. The valve core is provided with a notch surface and a through hole, and a gear is coaxially arranged on the rotating shaft of the valve core.

[0014] The circulating cooling device for thermoplastic laminate molding as described above: the driving component includes a moving rod fixed to the passive block, one end of the moving rod away from the passive block is slidably connected to a fixing member disposed on the base, and a limiting ring is provided on the moving rod, the limiting ring is provided with a toothed plate that meshes with the gear, and a spring is also sleeved on the moving rod, one end of the spring abutting against the fixing member, and the other end abutting against the limiting ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] By setting up a conversion component and utilizing the coordination between the triggering structure and the switching structure, during the hot pressing process of the hot press plate, the water pump is used to first blow out the water remaining in the water-cooling pipe, thus avoiding interference from the water-cooling pipe to the hot pressing process.

[0017] During hot pressing, the valve core completely blocks the main pipeline and maintains suction through the secondary pipeline to ensure that the water cooling pipe does not affect the plywood bonding during the hot pressing stage, thereby improving the structural strength of the laminate.

[0018] After hot pressing is completed, the main pipeline is opened and the secondary pipeline is blocked. The water pump draws water through the water-cooling pipe to cool the laminate and make the plywood bonded stably. Attached Figure Description

[0028] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0029] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0030] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0031] Please see Figures 1-8 In this embodiment of the invention, a circulating cooling device for thermoplastic laminate molding includes:

[0032] The base 1 has a shelf 2 and a hot press plate 15 that are slidably mounted on the base 1. The shelf 2 is provided with a water-cooled plate 10, and the water-cooled plate 10 is provided with a main pipe and a secondary pipe. The main pipe is used to cool the laminate on the shelf 2.

[0033] Specifically, the aforementioned shelf 2 is used to place plywood, and the hot press plate 15 is connected to the base 1 through a hydraulic lifting structure (not shown in the figure). After the multi-layer plywood is stacked on the shelf 2, the hot press plate 15 is driven to move toward the shelf 2 by the hydraulic lifting structure, thereby hot pressing the multi-layer plywood placed on the shelf 2 to form an adhesive between the plywood, and finally producing a laminate.

[0034] The main pipeline connects to an external water storage tank and a water pump 11 mounted on the base 1. The secondary pipeline is connected to the main pipeline via a conversion assembly. The conversion assembly includes a trigger structure and a switching structure. The trigger structure is mounted on the hot press plate 15 and the base 1. During the hot pressing process of the hot press plate 15 descending, the trigger structure can drive the switching structure to operate, thereby blocking the main pipeline and the secondary pipeline. This allows the water pump 11 to first drain the water from the main pipeline and then pump the water from the water storage tank through the secondary pipeline, so that the laminate can be formed.

[0035] The main pipeline includes a water-cooled pipe 14 disposed in the water-cooled plate 10 and a ball valve 5 disposed on the base 1. The water-cooled pipe 14 has a serpentine structure, and one end of the water-cooled pipe 14 is connected to the water pump 11, and the other end is connected to the main pipe port 502 of the ball valve 5.

[0036] The secondary pipeline includes a bypass pipeline 8, one end of which is connected to the outlet of the water-cooled pipe 14, and the other end is connected to the secondary port 501 of the ball valve 5.

[0037] In detail, the ball valve 5, water-cooled pipe 14, bypass pipe 8, and water pump 11 form a structure as follows: Figure 4 , Figure 5 , Figure 6The channel circuit is provided with an inlet pipe 9 on the ball valve 5. The outlet of the water pump 11 is connected to the outlet pipe 12. The inlet pipe 9 is connected to an external water storage tank. With the cooperation of the conversion component, the water pump 11 can pump the water in the water storage tank through the water cooling pipe 14 to the outlet pipe 12 for discharge. During this process, the water flowing in the water cooling pipe 14 can cool the hot-pressed laminate, thereby ensuring that the material is firmly bonded.

[0038] Specifically, a pressure valve 13 is provided at the connection section between the water-cooled pipe 14 and the ball valve 5. The pressure valve 13 can withstand extremely high pressure so that when the conversion component blocks the auxiliary pipe port 501 and the main pipe port 502 during the hot pressing process of the hot pressing plate 15, the continuously pumping water pump 11 can, with the cooperation of the pressure valve 13, pump out the water remaining in the water-cooled pipe 14, so that the water-cooled pipe 14 will not affect the hot pressing process, thereby facilitating the bonding between plywood.

[0039] For details, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 The triggering structure includes a triggering element and a passive element. The triggering element includes a triggering block 3 disposed on the hot press plate 15, and the triggering block 3 is provided with a triggering surface 301.

[0040] The passive component includes a passive block 4 slidably disposed on the base 1, and the passive block 4 is provided with an abutment surface 401.

[0041] The switching structure includes a switching component and a driving component. The switching component includes a valve core 17 that is rotatably and sealed on the ball valve 5. The valve core 17 is provided with a notch surface 1701 and a through hole 1702, and a gear 16 is coaxially provided on the rotating shaft of the valve core 17.

[0042] Specifically, please see Figure 7 The aforementioned notch surface 1701 is set in the shape of... Figure 7 As shown in the notch pattern, in the initial state, the notch surface 1701 faces the water inlet pipe 9, the water inlet pipe 9 is coaxial with the through hole 1702, and the valve core 17 blocks the secondary pipe port 501. At this time, the water pump 11 works and can pump the water in the water storage tank to the water outlet pipe 12 through the ball valve 5 and the water cooling pipe 14, thereby cooling the laminate on the shelf 2.

[0043] The driving component includes a movable rod 7 fixed to the passive block 4. One end of the movable rod 7 away from the passive block 4 is slidably connected to a fixing member 6 provided on the base 1. A limit ring 701 is provided on the movable rod 7. A toothed plate 18 that meshes with the gear 16 is provided on the limit ring 701. A spring 19 is also sleeved on the movable rod 7. One end of the spring 19 abuts against the fixing member 6, and the other end abuts against the limit ring 701.

[0044] Specifically, the spring 19 is always in a compressed and stored state. In the compressed and stored state, the spring 19 pushes the passive block 4 away from the fixed part 6. At this time, the toothed plate 18 and the gear 16 cooperate to make the notch surface 1701 face the water inlet pipe 9, the through hole 1702 is coaxial with the water inlet pipe 9, and the valve core 17 blocks the secondary pipe port 501.

[0045] When the hot platen 15 descends, the water pump 11 simultaneously performs a suction operation. Subsequently, the water pump 11 can pump the water in the water storage tank through the ball valve 5 and the water cooling pipe 14 to the water outlet pipe 12, thereby replacing the water previously left in the water cooling pipe 14.

[0046] As the hot press plate 15 descends to the point of contact with the plywood, the triggering surface 301 of the triggering block 3 contacts the abutting surface 401 of the passive block 4. With the continued descent of the triggering block 3, the pressure exerted by the triggering surface 301 on the abutting surface 401 forces the passive block 4 to move to the right (in conjunction with...). Figure 1 During this process, the spring 19 is further compressed, and the passive block 4 pulls the toothed plate 18 to move to the right, thereby causing the valve core 17 to rotate clockwise. When the valve core 17 rotates, the water inlet pipe 9 is always engaged with the notch surface 1701, and the valve core 17 can simultaneously block the auxiliary pipe port 501 and the main pipe port 502. At this time, the water pump 11, which performs the suction operation, can pump out the water in the water-cooled pipe 14 with the cooperation of the pressure valve 13, so that the plywood can be quickly bonded together.

[0047] When the trigger surface 301 separates from the contact surface 401, the passive block 4 drives the toothed plate 18 to move the maximum distance. At this time, the through hole 1702 is connected to the secondary pipe port 501. At this time, the water pump 11 can pump the water in the water storage tank to the outlet pipe 12 through the ball valve 5 and the side branch pipe 8 so that the water pump 11 can work normally.

[0048] When hot pressing is complete and the hot pressing plate 15 resets, the trigger block 3 gradually separates from the passive block 4. Subsequently, under the action of the spring 19, the passive block 4 drives the toothed plate 18 to reset to the left, so that the valve core 17 returns to its initial position. At this time, the water pump 11 can pump water from the water storage tank to the outlet pipe 12 through the water cooling pipe 14. During this process, the water flowing in the water cooling pipe 14 can be used to cool the laminate after hot pressing. After working for a period of time, the laminate is cooled and the water pump 11 will automatically stop working.
