Description

Technical Field

[0001] The utility model relates to the technical field of stair tread production devices, in particular to a mold for producing curved surface ceramic plate stair treads. Background Art

[0002] Ceramic panels can be bent into curved panels through heat processing, which can be used for yin and yang corners in architectural decoration, thereby avoiding the appearance of sharp corners and increasing safety in use. Utilizing the above characteristics, ceramic panels can be directly bent into stair treads with corners under the heat processing technology of ceramic panels. However, in the current processing process, the mold used to produce stair treads lacks an effective fixing device, and the ceramic panels lack effective fixation during the molding process. Therefore, there is a disadvantage that the ceramic panels will deviate during the processing process. In this regard, the present application specifically proposes a mold for producing curved ceramic panel stair treads. Utility Model Content

[0018] The following is combined with Figure 1-5 The specific implementation methods of the utility model are further described in detail.

[0019] Embodiment 1, the technical solution is that when the present application is in use, the pressing block 12 and the lower mold 1 are both made of high temperature resistant materials, so as to be able to withstand the high temperature of the heated and softened ceramic plate 20. The heated and softened ceramic plate 20 is placed in the molding area 2 of the lower mold 1, and then the hydraulic telescopic rod 15 of the lifting assembly is started to extend, and the extension of the hydraulic telescopic rod 15 will drive the upper mold 5 to move downward. During the downward movement of the upper mold 5, the pressing block 12 of the clamping device will first abut against the upper end of the softened ceramic plate 20. As the hydraulic telescopic rod 15 continues to extend and drives the upper mold 5 to move downward, the pressing rod 11 will move relative to the sleeve 10 and compress the spring 13. Under the reaction force of the spring 13, the clamping device can press the softened ceramic plate 20 through the pressing block 12. Under the action of the clamping device, the deviation during the stair step forming process is avoided.

[0020] Embodiment 2, based on embodiment 1, specifically, when the present application is in use, the molding area 2 at the upper end of the lower mold 1 is as shown in the accompanying drawings of the specification. Figure 1 The ceramic plate 20 shown is used to place the heated and softened ceramic plate 20, and the left end of the ceramic plate 20 protrudes from the left edge of the forming area 2, so that it can be bent under the action of the die to form stair steps. The connecting beam 4 on the support rod 3 is connected to the hydraulic telescopic rod 15 of the lifting component through the mounting block. The extension of the hydraulic telescopic rod 15 will drive the upper die 5 to move downward for the forming operation. After the forming, the hydraulic retractable rod will retract to drive the upper die 5 to move upward and reset.

[0021] During the forming operation, the heated and softened ceramic plate 20 is first placed in the forming area 2, and then the hydraulic telescopic rod 15 is driven to extend, and then the hydraulic telescopic rod 15 drives the upper die 5 to move downward. During the downward movement of the upper die 5, the pressing block 12 first contacts the heated and softened ceramic plate 20, so as to press the heated and softened ceramic plate 20 through the pressing block 12, so as to avoid the ceramic plate 20 being deflected during the forming process and affecting the forming quality. As the upper die 5 continues to move downward, since the pressing block 12 has abutted against the upper end of the heated and softened ceramic plate 20, the pressing rod 11 will slide relative to the sleeve 10, and then the spring 13 will be compressed. The reaction force of the spring 13 can further increase the positive pressure of the pressing block 12 on the heated and softened ceramic plate 20 to ensure the pressing effect; in the process of the upper die 5 continuing to move downward, the lower edge of the vertical plate 7 will also act on the heated and softened ceramic plate 20 to bend it downward, until the hydraulic telescopic rod 15 drives the upper die 5 to move to the lower limit position, at this time as shown in the accompanying drawings of the specification Figure 4 As shown, the heated and softened ceramic plate 20 will be bent into a shape that adapts to the upper die 5, that is, the forming operation of the stair treads is completed, and a first fillet 18 is inverted at the connection between the horizontal plate 6 and the vertical plate 7, and a second fillet 19 is inverted at the left edge of the forming area 2. A smooth curved surface structure will be formed at the turning point of the stair treads formed under the action of the first fillet 18 and the second fillet 19.

[0022] Correspondingly, after the stair treads are pressed and formed, the hydraulic telescopic rod 15 is started to move upward, thereby driving the upper die 5 to move upward and reset. During the upward movement and reset of the upper die 5, the spring 13 will also automatically extend to drive the pressing rod 11 to reset relative to the sleeve 10.

[0023] Embodiment 3, on the basis of embodiment 2, the sleeve 10 is fixed at a position coaxial with the through hole 8 by the vertical rod 9, when the upper pressing die moves downward to the lower limit position, the pressing block 12 is hidden in the through hole 8, and the sleeve 10 and the pressing rod 11 are vertically slidably connected through the cooperation of the vertical groove 16 and the slider 17.
