[0042] Example 2

[0043] On the basis of Example 1, a preferred embodiment of the superplastic thermoforming machine tool heating device provided by the present invention is as follows: Figures 1 to 6 As shown: the positioning component 13 includes: a through groove 1308 opened on one side of the inner wall of the heating groove 15; a positioning groove 1303 symmetrically opened on the inner wall of the through groove 1308; a positioning spring 1304 fixedly connected to the inner wall of the positioning groove 1303, one end of the positioning spring 1304 is fixedly connected to a sliding block 1305, one end of the sliding block 1305 is fixedly connected to a sliding column 1306 extending to the interior of the heating groove 15, one end of the sliding column 1306 is fixedly connected to a movable clamping seat 1307; a connecting rod 1301 fixedly connected to one end of the two movable clamping seats 1307; and a fixed clamping seat 1302 fixedly connected to the other side of the inner wall of the heating groove 15.

[0044] In this embodiment, the two movable holders 1307 are driven to slide by toggling the connecting rod 1301, so that the sliding column 1306 and the sliding block 1305 slide to compress the positioning spring 1304 until the movable holder 1307 slides into the through groove 1308. At this time, the other side of the heating plate 14 is separated from the interior of the fixed holder 1302, and then the heating plate 14 is pulled to make the other side detach from the interior of the movable holder 1307, and then the heating plate 14 can be disassembled for easy maintenance or replacement.

[0045] In a further preferred embodiment of the present invention, the fixed card seat 1302 and the movable card seat 1307 are C-shaped, and the fixed card seat 1302 and the movable card seat 1307 are used for the clamping installation of the two sides of the heating plate 14.

[0050] The working principle of the utility model is as follows: firstly, the pneumatic telescopic rod 1, the heating wire 10 and the heating plate 14 are electrically connected to the control terminal of the superplastic thermoforming machine tool. Then, when the heating operation is required, the pneumatic telescopic rod 1 can be started first, so that the heat preservation cover 3 is lowered so that the upper mold 7 and the lower mold 12 are molded together. At the same time, the heat preservation cover 3 will be tightly covered on the top of the heat preservation cover 4 and the heat preservation door body 5. The heating wire 10 and the heating plate 14 are started through the external control terminal for heating treatment. At the same time, the heat preservation cover 3, the heat preservation cover 4 and the heat preservation door body 5 form a closed space to avoid the leakage of heat and improve the corresponding heating effect.

[0051] At the same time, the mounting block 903 can be driven to slide down by toggling the pull rod 902 to compress the mounting spring 906 until it completely enters the fixing groove 907, and then the heat preservation cover 4 is pushed to make the clamping block 901 completely disengage from the inside of the clamping groove 904, thereby realizing the removal of the heat preservation cover 4. During installation, the pull rod 902 is first toggled to make the mounting block 903 slide down, and then the clamping block 901 is clamped into the inside of the clamping groove 904, and the pull rod 902 is released, and the elastic force of the mounting spring 906 is used to make the mounting block 903 slide up to limit one end of the clamping block 901, thereby improving the firmness and stability of the clamping block 901 and the inside of the clamping groove 904. After the heat preservation cover 4 and the heat preservation door body 5 are removed, it is convenient to maintain the heating wire 10, disassemble and replace the lower mold 12, or disassemble, maintain and replace the heating plate 14;

[0052] After the upper mold 7 and the lower mold 12 are disassembled, the two movable holders 1307 can be driven to slide by toggling the connecting rod 1301, so that the sliding column 1306 and the sliding block 1305 slide and compress the positioning spring 1304 until the movable holder 1307 slides into the through groove 1308. At this time, the other side of the heating plate 14 is separated from the interior of the fixed holder 1302, and then the heating plate 14 is pulled to make the other side detach from the interior of the movable holder 1307, so that the heating plate 14 can be disassembled for easy maintenance or replacement. During installation, the connecting rod 1301 is first toggled to drive the movable holder 1307 to slide, and then one side of the heating plate 14 is clamped into the interior of the fixed holder 1302, and then the connecting rod 1301 is released, and the elastic force of the positioning spring 1304 is used to make the movable holder 1307 clamped to the other side of the heating plate 14, and then the heating plate 14 is clamped and installed through the fixed holder 1302 and the movable holder 1307.
