TECHNICAL FIELD
[0001] The present patent relates to a molding device for hot-pressing parts, in particular, an automatic integrated molding device capable of accelerating work efficiency. BACKGROUND
[0002] For the preparation of ordinary polyurethane flat panel, generally, a sheet (base material) is formed after spraying polyurethane foaming material on a sponge board, then heated, sent into a hot press for hot pressing, and then cooled and demolded to form. For the preparation of polyurethane arc-shaped panel with large size (such as automobile outer wheel cover), the sheet periphery is inserted into the material nails on the periphery of the nail frame, and the nail frame is heated and hot-pressed together with the base material. In this way, the sheet periphery is pulled by the material nails, and the edge of the base material cannot shrink inward during hot pressing, so that the arc-shaped polyurethane panel (such as the outer wheel cover) can be formed. Obviously, compared with the preparation of polyurethane flat panel, the preparation of arc-shaped polyurethane panel (such as the outer wheel cover) not only needs to fix the sheet periphery on the nail frame (insert the material nails on the periphery of the nail frame), but also needs to take down the formed part from the nail frame after the arc-shaped polyurethane panel is formed, and at the same time, the problem of moving the nail frame together with the base material needs to be considered.
[0003] The conventional arc-shaped polyurethane panel is generally made by following multiple steps such as placing the sheet, pressing the sheet into the nail frame, heating, hot-pressing and cooling, taking down the formed part from the nail frame, etc. Each step is completed in a work station, which occupies a large work site, and the nail frame is troublesome to transfer between different work stations, which takes a long time. Moreover, because the operation time of different steps is different, some work stations need to stop and wait for the completion of operation of other work stations, which seriously affects the work efficiency.

When the swing pushing rod 992 swings forward, it can contact the rear end of the nail frame and push the nail frame to move forward until the front end of the nail frame contacts the limiting block 991. When the swing pushing rod 992 swings backward and the upper part of the swing pushing rod 992 is lower than the bottom of the nail frame, the nail frame can move backward.
[0022] The beneficial effects of the present patent are as follows:
[0023] The upper track and the lower track are arranged in the heating station 5. When the sheet in the nail frame on the upper track is heated near the heating disc 55, the hot-pressing nail frame 4 with the cooled and formed parts can be moved backward from the lower track to the workbench 11 to perform the operation of taking out the parts and placing new sheets, thereby improving the operation efficiency.
[0024] When the heating disc 55 heats the sheet in the heating nail frame 3 on the upper track, the hot-pressing machine performs hot pressing and cooling forming on the sheet in the hot-pressing nail frame 4 on the lifting platform 94, and then moves the hot-pressing nail frame 4 with the cooled and formed parts backward to the lower track. That is, the heating and hot pressing, cooling, and moving the hot-pressing nail frame 4 to the lower track are performed synchronously, thereby reducing the waiting time.
[0025] The step of moving the heating nail frame 3 with the heated sheet from the upper track to the lifting platform 94 can be performed synchronously with the step of moving the taking and placing nail frame 2 on the workbench 11 from the taking and placing station to the upper track of the heating station 5, thereby reducing the waiting time and improving the operation efficiency.
[0026] Thanks to the lower track, the sheet in the hot-pressing nail frame 4 can move backward after being hot-pressed and cooled and formed on the hot-pressing machine, i.e., move from the front to the back, and then be smoothly returned to the taking and placing station 1 through the transfer of the lower track, thereby avoiding the hot-pressing nail frame 4 returning to the taking and placing station 1 through other long-distance paths.
[0027] The taking and placing station 1 integrates the lower pressing plate 12 and the upper top plate 14, so that the nail frame does not need to be moved in one station, and both the taking out of the formed parts from the nail frame and the pressing of the sheet into the nail frame are achieved, thereby saving the operation time and simplifying the overall layout of the integrated forming device and the overall structure of the machine.
[0028] The whole cycle forming method only needs to use 3 nail frames 100, reduces the circulation time of the nail frame 100. The structure of each nail frame is the same. It should be noted that in the forming process of any part, each nail frame 100 needs to cycle through the steps of placing the sheet, pressing the sheet into the nail frame, heating, hot pressing, cooling, and taking off the formed part from the nail frame. The nail frame 2 is taken and placed, the nail frame 3 is heated, and the nail frame 4 is hot pressed. Each nail frame 100 is in different positions with different names. That is, the nail frame on the workbench 11 is called the taking and placing nail frame 2. When the taking and placing nail frame 2 moves to the upper track, it becomes the heating nail frame 3. When the heating nail frame 3 moves to the lifting platform 94, it becomes the hot pressing nail frame 4. When the hot pressing nail frame 4 moves to the lower track, it is still called the hot pressing nail frame 4. When the hot pressing nail frame 4 moves to the workbench 11, it is the taking and placing nail frame 2.
[0029] In the non-heating state, the upper track is flush with the workbench 11, and the lifting platform 94 can also be lifted to the position of taking in and out of the nail frame flush with the upper track. The nail frame moves from the workbench 11 of the taking and placing station 1 to the upper track, or the nail frame moves from the upper track to the lifting platform 94. It is very fast and convenient. In the heating state, the lower track is flush with the workbench 11, and the lifting platform 94 can also be lifted to the position of taking in and out of the nail frame flush with the lower track. The nail frame moves from the lower track to the workbench 11, or the nail frame moves from the lifting platform 94 to the lower track. It is also very fast and convenient.
[0030] The lifting drive device 400 drives the left lifting frame 51 and the right lifting frame 52 to slide synchronously up and down, which can realize the rapid change of the heating station 5 between the heating state and the non-heating state.
[0031] The upper push-pull block 65 is swung to different positions relative to the upper sliding block 63 to realize connection or disconnection with the nail frame. The lower push-pull block 66 is swung to different positions relative to the lower sliding block 64 to realize connection or disconnection with the hot pressing nail frame 4. The operation is fast and convenient.
[0032] The heating frame positioning device 800 can fix the heating nail frame 3 on the upper track in the heating state and when the upper track and the lower track are lifted to prevent it from moving forward and backward. The hot pressing frame positioning device 880 can fix the hot pressing nail frame 4 on the lower track in the heating state and when the upper track and the lower track are lifted to prevent it from moving forward and backward. The heating frame positioning device 800 and the hot pressing frame positioning device 880 both use thrust cylinders, thrust rods, clamping cylinders, sleeves, clamping rods, etc. They can quickly clamp or release the nail frame in the forward and backward directions, and when the clamping of the nail frame is released, it is away in the forward and backward directions, which will not hinder the forward and backward movement of the nail frame.
[0033] The heat insulation disc 59 can isolate the radiation heating of the heating disc 55 on the hot pressing nail frame 4 on the lower track.
[0034] The smoke hood and the smoke exhaust passage can suck and exhaust the exhaust gas generated when the sheet is heated, so as to prevent pollution.
[0035] The left rail 161, the left upper rail 531 in the non-heating state, and the left hot-pressing rail 951 at the position of entering and exiting the frame are collinear, and the right rail 162, the right upper rail 532 in the non-heating state, and the right hot-pressing rail 952 at the position of entering and exiting the frame are collinear.
[0036] The upper slide rail 61 is outside the upper rail (the left upper rail 531 or the right upper rail 532), the take-and-place slide rail 17 is inside the take-and-place rail 16 (the left rail 161 or the right rail 162), and the take-and-place push-pull block 19 fixed on the take-and-place slide block 18 sliding on the take-and-place slide rail 17 has a clamping plate 191 extending laterally (left-right direction), which extends into the recess 672 extending in the up-down direction on one end of the frame; therefore, after the take-and-place push-pull block 19 drives the frame to move forward on the upper rail, the take-and-place push-pull block 19 does not need to move and does not hinder the up-down movement of the upper rail and the lower rail and the frame on the upper rail and the lower rail. In this way, the sequential operation of each step can be ensured by a simple structure.
[0037] The pressing device 300 can press the take-and-place frame 2 on the take-and-place rail 16 when the parts formed on the take-and-place frame 2 are ejected upward by the upper top plate 14. The pressing device 300 uses the clamping hook 31 with a bottom surface flush with the upper surface of the frame, the pull hook 32, the moving block 33, and the pressing cylinder 34, which can quickly press the front and rear ends of the frame on the workbench 11 or quickly release the pressing of the frame, and when the pressing of the frame is released, the moving block 33 and the pull hook 32 can move away from the front end of the frame in the front-rear direction of the frame, so as not to hinder the forward and backward movement of the frame.
[0038] In the hot-pressing station 9, the lifting cylinder 98 drives the lifting block 96 to lift the lifting table 94 up and down, so as to lift the frame on the lifting table 94 to the required height, and the frame and the lifting table 94 can move downward with the upper die 91 to combine with the lower die 92 to realize hot pressing. The hot-pressing station 9 has a simple and practical overall structure.
[0039] When the swing push rod 992 in the push device 99 swings forward and upward, the frame on the lifting table 94 can be pushed forward, so that the front end of the frame contacts the limiting block 991 to quickly fix the frame on the lifting table 94; when the swing push rod 992 swings backward and downward, the fixing of the frame on the lifting table 94 is released, and the backward movement of the frame is not hindered. The push device 99 can quickly fix or release the hot-pressed frame 4 by a simple structure, and the action is reliable. BRIEF DESCRIPTION OF DRAWINGS
