The thumb of the hand-held fixed block 12 presses the extrusion block 13, the extrusion block 13 drives the fixed rod 17 to move, the fixed rod 17 moves to pull the two pull ropes 18, the two pull ropes 18 change the direction of force through the first fixed pulley 20 and the second fixed pulley 21, first pull the abutting block 16 close to the stable block 14, when the damping spring between the stable block 14 and the abutting block 16 is extruded to the maximum extent, the pull rope 18 drives the stable block 14 and the abutting block 16 into the stable block slot, then insert the support rod 11 into the insertion hole of the support column 2, after releasing the hand, the damping spring drives the extrusion block 13 to reset, because the elastic coefficient of the damping spring between the stable block 14 and the inside wall of the stable block slot is greater than the elastic coefficient of the damping spring between the stable block 14 and the abutting block 16, the damping spring first drives the stable block 14 to move out of the stable block slot, then the abutting block 16 abuts against the side wall of the support column 2 under the action of the damping spring, then place the moving steel plate 8 on the plurality of support rods 11, the plurality of support rods 11 support the moving steel plate 8, the stable block 14 can provide the function of limiting, avoid the support rod 11 from slipping out of the insertion hole, the abutting block 16 cooperates with the damping spring to abut against the side wall of the support column 2, avoid the gap between the stable block 14 and the support column 2 to cause the support rod 11 to displace and shake, make the support rod 11 provide support for the moving steel plate 8 more stable.

[0035] In one embodiment, as Figure 6As shown, the damping spring is fixedly connected between the extrusion block 13 and the inner side wall of the extrusion block slot. The damping spring drives the extrusion block 13 to reset.

[0036] The above embodiment discloses a simple multi-layer foaming device. The moving steel plate 8 is a 20 cm thick steel plate with many air holes, which will not easily deform and facilitate heat transfer.

[0037] The high-temperature camera 5 is installed on the moving steel plate 8, which can be wirelessly connected to a computer and can be used to observe the foaming and size of the resin plate in the oven in real time.

[0038] Before foaming, the lowermost moving steel plate 8 is fixed, with a gap of 1.2 times the estimated foamed plate thickness left between the bottom support plate. The extrusion block 13 is pressed by the thumb of the hand-held fixed block 12, which drives the fixed rod 17 to move, pulling the two pull ropes 18. The two pull ropes 18 change the direction of the force through the first fixed pulley 20 and the second fixed pulley 21, first pulling the abutment block 16 close to the stabilizing block 14. When the damping spring between the stabilizing block 14 and the abutment block 16 is compressed to the maximum extent, the pull rope 18 drives the stabilizing block 14 and the abutment block 16 into the stabilizing block slot. Then the support rod 11 is inserted into the insertion hole of the support column 2. After releasing the hand, the damping spring drives the extrusion block 13 to reset. Because the elastic coefficient of the damping spring between the stabilizing block 14 and the inner side wall of the stabilizing block slot is greater than that of the damping spring between the stabilizing block 14 and the abutment block 16, the damping spring first drives the stabilizing block 14 to move out of the stabilizing block slot, and then the abutment block 16 abuts against the side wall of the support column 2 under the action of the damping spring. Then the moving steel plate 8 is placed on the support rods 11, which support the moving steel plate 8. The stabilizing block 14 can provide a limiting function to prevent the support rod 11 from slipping out of the insertion hole. The abutment block 16 abuts against the side wall of the support column 2 in cooperation with the damping spring, preventing the stabilizing block 14 and the support column 2 from having a gap that causes the support rod 11 to shift and shake, making the support rod 11 provide more stable support to the moving steel plate 8.

[0039] Before foaming, the resin plate is weighed and sized, the foaming density and the size after foaming are calculated, and the resin plate is placed on the support plate 9 at the corresponding position corresponding to the scale of the scale plate 7 for easy observation of the size.

[0040] The moving steel plate 8 and the support plate 9 have a gap of 1.2 times the thickness of the foamed plate, which can measure the foaming position of the plate and prevent the resin plate from deforming severely. Because the resin plate is soft at high temperature and will tend to be flat when pressed by something with a certain weight, the foamed plate will be relatively flat, the internal stress will be reduced, and the overall performance of the plate will be guaranteed.

[0041] The lower mobile steel plate 8 and the upper support plate 9 are spaced apart by a gap twice the thickness of the foam plate, facilitating lifting of the mobile steel plate 8 and removal of the plate that has been foamed.

[0042] When removing the plate that has been foamed, the frame is first pulled out of the oven, and the mobile steel plate 8 is lifted by the lifting hook through the lifting plate 10. In this way, the plate at each position can be conveniently removed, and after removal, the mobile steel plate 8 is returned to the original position and pushed into the oven for continuous foaming.

[0043] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited thereto, and any person skilled in the art can easily think of changes or replacements within the technical scope disclosed in the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
