[0018] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments and drawings. However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all belong to the protection scope of the present invention.

[0019] The following describes the specific embodiments of the present utility model in conjunction with the drawings.

[0020] Embodiment 1

[0021] As Figures 1-3 shown, a ceramic preparation sintering furnace includes a housing. A furnace body is provided inside the housing. Connecting rods 2 extending to the inside of the furnace body are provided at both the upper and lower ends of the housing. Placement plates 7 are provided at the ends of the two connecting rods 2 and inside the furnace body. Multiple reinforcing ribs 8 are provided on the side surface of the placement plate 7. Bolts 9 inserted into the side surface of the connecting rod 2 are provided on the bottom side surface of the placement plate 7.

[0022] The housing includes a housing body 1 and a sealing door 3 which is arranged on the side of the housing body 1 and covers the surface of the housing body 1.

[0023] The furnace body includes a furnace body 4 arranged inside the housing body 1, a sealing plate 6 installed on the side of the sealing door 3 and connected to the furnace body 4, and a plurality of heaters 5 arranged on the inner wall of the furnace body 4 and the side of the sealing plate 6.

[0024] The two connecting rods 2 are arranged vertically and coaxially. The coaxial arrangement enables the forces of the connecting rods 2 to be synchronized.

[0025] The bottom end of the placement plate 7 is provided with a groove, and both sides of the top end of the connecting rod 2 are provided with key grooves. The connecting rod 2 is inserted inside the groove of the placement plate 7, and the size of the connecting rod 2 is adapted to the size of the groove of the placement plate 7. Among them, the side of the groove of the placement plate 7 is open, and both sides of the bottom end of the groove of the placement plate 7 are provided with chutes. Both sides of the top end of the connecting rod 2 and at the key groove positions are provided with sliders. The sliders of the connecting rod 2 are located inside the chutes of the placement plate 7. The cooperation between the groove of the placement plate 7 and the shape of the top end of the connecting rod 2 enables the placement plate 7 to be replaced on the connecting rod 2 to adapt the placement plate 7 to the mold, and at the same time restricts the up and down movement of the placement plate 7 to prevent the placement plate 7 located above from falling off.

[0026] The top end of the placement plate 7 is square, and there is a gap between the edge of the placement plate 7 and the inside of the furnace body. Among them, the size of the placement plate 7 is the maximum size that the inside of the furnace body can bear. This structure enables the placement of the maximum number of molds inside the furnace body, improving the single - processing efficiency.

[0027] One end of the reinforcing rib 8 is located at the edge of the placement plate 7. This structure enables the top edge of the placement plate 7 to also be a stress point.

[0028] Working principle:

[0029] During use, the placement plate 7 is translated and connected to the connecting rod 2, so that the top end of the connecting rod 2 is located inside the bottom end of the placement plate 7, enabling the top of the placement plate 7 to place molds. At the same time, through the size of the placement plate 7, multiple molds can be placed above the placement plate 7. And through the extension of the connecting rod 2, the distance between the two placement plates 7 is reduced, causing the placement plate 7 to squeeze the molds. At the same time, through the support of a plurality of reinforcing ribs 8, the multiple molds on the placement plate 7 are evenly stressed, improving the efficiency of single - time ceramic preparation.

[0030] The above has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed. The scope of protection claimed by the present utility model is defined by the appended claims and their equivalents.
