[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0032] like Figure 1-4As shown, a porcelain powder baking furnace for denture production includes a crucible cover 1 and a mica cover 2 disposed in the crucible cover 1, a heating chamber 100 is formed inside the mica cover 2, and a clamping chamber 200 is formed between the mica cover 2 and the crucible cover 1;

[0033] The mica cover 2 is provided with mica plates 21 arranged in a linear array and facing the clamping cavity 200;

[0034] It also includes an electric heating wire 4 surrounding the outer wall of the mica cover 2 and located on the mica board 21;

[0035] The mica cover 2 is clamped with heat dissipation plates 3 arranged in a linear array and facing the heating chamber 100;

[0036] The mica cover 2 is provided with air holes 22 , and the air holes 22 are used to connect the heating chamber 100 and the clamping chamber 200 .

[0037] Specifically, a slide rail 71 is disposed on the first base 7, and a machine head 8 is disposed on the slide rail 71. The crucible cover 1 in the above embodiment is located inside the machine head 8, and the port extends out of the machine head 8.

[0038] When the second base 9 slidingly arranged on the slide rail 71 is driven by the lead screw 72 driven by the motor arranged in the slide rail 71, the second base 9 will be driven to move up with the porcelain plate 10, the porcelain plate 10 is plugged into the crucible cover 1, and the second base 9 is embedded in the rectangular boring groove 81 opened at the bottom of the machine head 8.

[0039] Secondly, a temperature sensor is arranged in the crucible cover 1 in the embodiment to detect the temperature of the electric heating wire 4 near the clamping cavity 200. When the temperature reaches a predetermined value, heating is stopped, and when the temperature is lower than the predetermined value, heating is started, thereby realizing an overheating protection for the electric heating wire.

[0040] Furthermore, the above components can be controlled to run according to a predetermined program by controlling the touch screen on the machine head 8, and the control program and electronic components are common technical knowledge known to those skilled in the art and will not be described in detail.

[0041] In the above technology, the mica cover 2 is used as a carrier of the electric heating wire to install the electric heating wire 4, and then the heat dissipated by the electric heating wire 4 to the clamping cavity 200 is transferred to the heating cavity 100 by a heat dissipation plate 3 located on the mica cover 2 in a honeycomb manner and facing the heating cavity 100, thereby increasing the temperature inside the heating cavity 100.

[0042] As an embodiment further provided by the present invention, the electric heating wire 4 is located on a section of the mica board 21 and is in the same horizontal plane as the heat dissipation plate 3 .

[0043] As another embodiment further provided by the present invention, the heat dissipation plate 3 is divided into a buckle foot 31, a first connecting portion 32, a bent portion 33 and a U-shaped member 34 according to the structure;

[0044] The first end of the first connecting portion 32 is connected to the bent portion 33, and is connected to one end of the U-shaped member 34 through the bent portion 33;

[0045] The second end of the first connection portion 32 is connected to the buckle foot 31 and is buckled onto the mica cover 2 through the buckle foot 31 , so that the first connection portion 32 is perpendicular to the mica cover 2 .

[0046] Specifically, the heat of the electric heating wire 4 in the embodiment is transferred to the heat dissipation plate 3 , and because the heat dissipation plate 3 is formed by bending an aluminum alloy, the heat dissipation surface is the largest, thereby ensuring the heat transfer in the heating chamber 100 .

[0047] As another embodiment further provided by the present invention, a wire spring 35 with one end abutting against the mica cover 2 is disposed in the U-shaped member 34 .

[0048] Specifically, the wire spring 35 is used to further enhance the heat transfer and increase the heat dissipation surface, thereby ensuring the heat transfer in the heating chamber 100 .

[0049] Secondly, a mica peripheral sheet 5 is centrally arranged in the clamping cavity 200 to isolate the crucible cover 1 from the electric heating wire 4.

[0050] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
