Description

Technical Field

[0001] This utility model relates to the technical field of hot pressing processing equipment, and in particular to a hot pressing processing equipment for plastic sheets. Background Technology

[0002] A relatively special plastic processing method that processes thermoplastic sheets into various products. The sheet is clamped on a frame and heated to a softened state. Under the action of external force, it is made to fit tightly against the mold surface to obtain a shape similar to the mold surface.

[0003] Chinese utility model patent CN218557740U discloses a plastic sheet hot pressing processing device, including a processing table, a mounting frame, and a bottom mold for hot pressing and shaping the plastic sheet. The mounting frame is detachably connected to the upper surface of the processing table. The device also includes a fixing frame and a hydraulic cylinder. The fixing frame is fixedly connected to the upper surface of the processing table, and the hydraulic cylinder is embedded in the upper end of the fixing frame. During hot pressing, the hot pressing material is placed in the shaping cavity of the bottom mold and heated. The hydraulic cylinder on the fixing frame drives the hot pressing plate to hot press the bottom mold, thereby shaping the hot pressing material.

[0004] In the process of hot pressing plastic sheet, the aforementioned plastic sheet hot pressing device directly removes the pressed product from the molding cavity. However, the hot-pressed product is in a compacted state, and directly removing the product increases the difficulty of product removal. Utility Model Content

[0005] To address the aforementioned problems, this utility model provides a plastic sheet hot pressing processing device.

[0006] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a plastic sheet hot pressing processing device, comprising a processing table with a hollow structure and an open top, a hot pressing mechanism being provided on the processing table, a plurality of sliding seats being slidably arranged inside the processing table, a forming mold with an annular structure being fixed on the top of the sliding seats, a lifting seat being slidably arranged inside the forming mold, the distance between the top of the lifting seat and the top of the sliding seat being greater than the distance between the top of the forming mold and the top of the sliding seat, a displacement component for driving the plurality of sliding seats to move being provided on the processing table, and a lifting component for driving the lifting seat to rise and fall being provided on the forming mold, wherein the number of sliding seats, the number of forming molds, the number of lifting seats, and the number of lifting components are all equal and their positions correspond one-to-one.

[0007] By adopting the above technical solution, the sliding seat is first moved to the position of the hot pressing mechanism by the displacement component, so that the molding die fixed to the sliding seat and the lifting seat connected to the molding die are both moved to the position of the hot pressing mechanism. At the same time, the lifting component lowers the lifting seat to the lowest position. At this time, the product to be hot-pressed is injected into the molding die until it is flush with the top of the molding die. Then, the hot pressing mechanism hot-presses the product in the molding die. After the hot pressing is completed, the sliding seat is moved away from the position of the hot pressing mechanism by the displacement component, and the lifting component raises and resets the lifting seat. The lifting seat drives the hot-pressed product out of the molding die, thereby reducing the difficulty of product removal.

[0008] Furthermore, the displacement assembly includes a threaded rod rotatably mounted in the machining table, a slide rod fixed in the machining table, and a displacement motor fixed in the machining table and driving the threaded rod to rotate. The threaded rod passes through multiple sliding seats and is threadedly connected, and the slide rod passes through multiple sliding seats and is slidably engaged.

[0009] By adopting the above technical solution, the displacement motor drives the threaded rod to rotate after it starts working, thereby causing the sliding seat that is threadedly connected to the threaded rod to move, thus achieving the purpose of moving the forming mold and the lifting seat.

[0010] Furthermore, the side wall of the processing table is provided with a lifting groove, the side wall of the forming mold is provided with a sliding groove, and the lifting assembly includes a sliding block slidably installed in the sliding groove, a lifting rod rotatably installed on the sliding block and slidably engaged with the lifting groove, and a guide rod fixed in the sliding groove. The sliding block is fixed to the lifting seat, and the guide rod passes through the sliding block and slidably engages with it.

[0011] By adopting the above technical solution, during the movement of the sliding seat towards the hot pressing mechanism, the forming mold connected to the sliding seat, the lifting seat connected to the forming mold, the sliding block connected to the lifting seat, and the lifting rod connected to the sliding block all move. Since the lifting rod slides in conjunction with the lifting groove, it first moves horizontally within the lifting groove, then descends, and finally moves horizontally again. During this process, the sliding block connected to the lifting rod and the lifting seat connected to the sliding block descend until the top of the lifting seat is slightly higher than the top of the sliding groove. At this point, the product can be injected into the forming mold for hot pressing. After hot pressing, the sliding seat moves away from the hot pressing mechanism, causing the forming mold, lifting seat, sliding block, and lifting rod to move. Under the action of the lifting groove, the lifting rod first moves horizontally within the lifting groove, then rises, and finally moves horizontally again. During this process, the sliding block and lifting seat rise and reset. At this point, the hot-pressed product is outside the forming mold, allowing it to be removed from the forming mold.

[0012] Furthermore, the hot pressing mechanism includes a mounting bracket fixed to the processing table, an electro-hydraulic push rod fixed to the mounting bracket, and a hot pressing plate fixed to the end of the push rod of the electro-hydraulic push rod.

[0013] By adopting the above technical solution, after the electro-hydraulic push rod is working, its push rod end extends to the maximum stroke, so that the hot press plate connected to the push rod end of the electro-hydraulic push rod descends and fits into the forming mold, thereby ensuring normal hot pressing operation.

[0014] Furthermore, the mounting frame is provided with two sets of feeding mechanisms symmetrically arranged about the electro-hydraulic push rod. The feeding mechanism includes a feeding assembly, which includes a storage box fixed to the mounting frame, a feed pipe fixed and connected to the top of the storage box, a heater fixed to the storage box and used for heating the plastic product, and a discharge pipe fixed and connected to the bottom of the storage box. The discharge pipe passes through the mounting frame and is fixed. An electromagnetic valve is provided on the discharge pipe. The feeding mechanism also includes a discharge assembly for discharging the product from the storage box.

[0015] By adopting the above technical solution, when the lifting seat is lowered to the lowest position, the inside of the molding mold is exactly below the discharge pipe. By opening the solenoid valve, the heated product in the storage box will be discharged from the discharge pipe and eventually flow into the molding mold, thus realizing the purpose of automatic material injection of the device and facilitating the use of the device.

[0016] Furthermore, the discharge assembly includes a discharge motor fixed to the top of the storage box, a rotating rod rotatably mounted on the inner top wall of the storage box, and a spiral blade fixedly sleeved on the rotating rod and located inside the discharge pipe. The output end of the discharge motor passes through the top of the storage box and is rotatably connected. The output end of the discharge motor is fixed to the discharge motor and coaxially arranged.

[0017] By adopting the above technical solution, after the discharge motor works, it drives the rotating rod to rotate, which causes the spiral blade connected to the rotating rod to rotate, so that the product can be evenly discharged from the discharge pipe.

[0018] Furthermore, the bottom of the sliding seat is rotatably mounted with rollers that are rolledly connected to the inner bottom wall of the processing table.

[0019] By adopting the above technical solution, the friction between the sliding seat and the processing table during movement is reduced.

[0020] In summary, the present invention has the following beneficial effects: In this application, by setting up a lifting component and a lifting groove, the lifting seat pushes the product that has been hot-pressed in the molding mold out of the molding mold, thereby reducing the difficulty of removing the product.

[0026] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0027] like Figure 1-4As shown in the embodiment of this application, a plastic sheet hot pressing processing device is disclosed, including a processing table 1, a hot pressing mechanism 2, a displacement component 6, a lifting component 7, and a feeding mechanism 9. The processing table 1 is a hollow structure with an open top. A lifting groove 8 is provided through the side wall of the processing table 1, and multiple sliding seats 3 are slidably arranged inside the processing table 1. A forming mold 4 with a ring structure is fixed to the top of the sliding seat 3. A sliding groove 10 is provided through the side wall of the forming mold 4, and a lifting seat 5 is slidably arranged inside the forming mold 4. The distance between the top of the lifting seat 5 and the top of the sliding seat 3 is greater than the distance between the top of the forming mold 4 and the top of the sliding seat 3. The number of sliding seats 3, the number of forming molds 4, the number of lifting seats 5, and the number of lifting components 7 are all equal and their positions correspond one-to-one. First, the sliding seat 3 is moved to the position of the hot pressing mechanism 2 by the displacement component 6, so that the molding mold 4 fixed to the sliding seat 3 and the lifting seat 5 connected to the molding mold 4 are both moved to the position of the hot pressing mechanism 2. At the same time, the lifting component 7 lowers the lifting seat 5 to the lowest position. At this time, the product to be hot-pressed is injected into the molding mold 4 until it is flush with the top of the molding mold 4. Then, the hot pressing mechanism 2 hot-presses the product in the molding mold 4. After the hot pressing is completed, the sliding seat 3 is moved away from the position of the hot pressing mechanism 2 by the displacement component 6, and the lifting component 7 raises and resets the lifting seat 5. The lifting seat 5 drives the hot-pressed product in the molding mold 4 out of the molding mold 4, thereby reducing the difficulty of removing the product.

[0028] The hot pressing mechanism 2 is mounted on the processing table 1 and includes a mounting frame 21, an electro-hydraulic push rod 22, and a hot pressing plate 23. The mounting frame 21 is fixed to the processing table 1, the electro-hydraulic push rod 22 is fixed to the mounting frame 21, and the hot pressing plate 23 is fixed to the push rod end of the electro-hydraulic push rod 22. After the electro-hydraulic push rod 22 is operated, its push rod end extends to its maximum stroke, causing the hot pressing plate 23 connected to the push rod end of the electro-hydraulic push rod 22 to descend and fit against the forming mold 4, thereby ensuring normal hot pressing operation.

[0029] The displacement assembly 6 is mounted on the processing table 1 and is used to drive the movement of multiple sliding seats 3. The displacement assembly 6 includes a threaded rod 61, a sliding rod 62, and a displacement motor 63. The threaded rod 61 is rotatably mounted inside the processing table 1. The threaded rod 61 passes through multiple sliding seats 3 and is threadedly connected. The sliding rod 62 is fixed inside the processing table 1. The sliding rod 62 passes through multiple sliding seats 3 and is slidably engaged. The displacement motor 63 is fixed on the processing table 1 and drives the threaded rod 61 to rotate. After the displacement motor 63 operates, it drives the threaded rod 61 to rotate, thereby causing the sliding seats 3 threadedly connected to the threaded rod 61 to move, thus achieving the purpose of moving the forming mold 4 and the lifting seat 5.

[0030] The lifting assembly 7 is mounted on the forming mold 4 and is used to drive the lifting seat 5 to rise and fall. The lifting assembly 7 includes a sliding block 71, a lifting rod 72, and a guide rod 73. The sliding block 71 is slidably installed in the sliding groove 10. The sliding block 71 is fixed to the lifting seat 5, and the lifting rod 72 is rotatably mounted on the sliding block 71 and slides in engagement with the lifting groove 8. The guide rod 73 is fixed in the sliding groove 10, passes through the sliding block 71, and slides in engagement with it. As the sliding seat 3 moves toward the hot pressing mechanism 2, the molding mold 4 connected to the sliding seat 3, the lifting seat 5 connected to the molding mold 4, the sliding block 71 connected to the lifting seat 5, and the lifting rod 72 connected to the sliding block 71 all move. Since the lifting rod 72 is slidably engaged with the lifting groove 8, the lifting rod 72 will first move horizontally along the lifting groove 8, then the lifting rod 72 will begin to descend, and finally the lifting rod 72 will move horizontally. During this process, the sliding block 71 connected to the lifting rod 72 and the lifting seat 5 connected to the sliding block 71 will descend until the top of the lifting seat 5 is slightly higher than the top of the sliding groove 10. At this time, the product can be injected into the molding mold 4 and the hot pressing operation can be performed. After hot pressing is completed, the sliding seat 3 moves away from the hot pressing mechanism 2, causing the forming mold 4, lifting seat 5, sliding block 71 and lifting rod 72 to move. Under the action of the lifting groove 8, the lifting rod 72 will first move horizontally along the lifting groove 8, then the lifting rod 72 will start to rise, and finally the lifting rod 72 will move horizontally. During this process, the sliding block 71 and the lifting seat 5 will rise and reset. At this time, the hot-pressed product is located outside the forming mold 4 so that the product can be taken out from the forming mold 4.

[0031] The feeding mechanism 9 is mounted on the mounting frame 21. Two sets of the feeding mechanism 9 are symmetrically arranged about the electro-hydraulic push rod 22. The feeding mechanism 9 includes a feeding assembly 91 and a discharging assembly 92. The feeding assembly 91 includes a storage tank 911, an inlet pipe 912, a heater 913, and a discharging pipe 914. The storage tank 911 is fixed to the mounting frame 21, and the inlet pipe 912 is fixed and connected to the top of the storage tank 911. The heater 913 is fixed to the storage tank 911 and used to heat the plastic product, and the discharging pipe 914 is fixed and connected to the bottom of the storage tank 911. The discharging pipe 914 passes through the mounting frame 21 and is fixed thereto, and a solenoid valve is installed on the discharging pipe 914. When the lifting seat 5 descends to its lowest position, the inside of the molding mold 4 is located directly below the discharge pipe 914. By opening the solenoid valve, the heated product in the storage box 911 will be discharged from the discharge pipe 914 and eventually flow into the molding mold 4, thus achieving the purpose of automatic material injection and facilitating the use of the device.

[0032] The discharge assembly 92 is used to discharge products from the storage bin 911. The discharge assembly 92 includes a discharge motor 921, a rotating rod 922, and a spiral blade 923. The discharge motor 921 is fixed to the top of the storage bin 911, and its output end passes through the top of the storage bin 911 and is rotatably connected. The output end of the discharge motor 921 is fixed to the discharge motor 921 and coaxially arranged. The rotating rod 922 is rotatably mounted on the inner top wall of the storage bin 911, and the spiral blade 923 is fixedly sleeved on the rotating rod 922 and located inside the discharge pipe 914. After the discharge motor 921 operates, it drives the rotating rod 922 to rotate, causing the spiral blade 923 connected to the rotating rod 922 to rotate, thus discharging the products evenly from the discharge pipe 914.

[0033] The bottom of the sliding seat 3 is rotatably mounted with a roller 11 that is rolledly connected to the inner bottom wall of the processing table 1. This reduces the friction between the sliding seat 3 and the processing table 1 when they move.
