Description

Technical Field

[0001] The utility model relates to the technical field of ceramic processing, and more specifically to a placement device for a ceramic sintering furnace. Background Art

[0002] A sintering furnace refers to a special equipment that allows powder compacts to obtain the required physical, mechanical properties and microstructure through sintering. The sintering furnace is used to dry the slurry on the silicon wafer, remove the organic components in the slurry, and complete the sintering of the aluminum back field and the gate line. In the production process of ceramic handicrafts, a high-temperature sintering process is required. The high-temperature sintering process generally requires a very high temperature and needs to be carried out in a sintering furnace.

[0003] The utility model patent with announcement number CN215864642U discloses a placing device for a ceramic sintering furnace, comprising a placing cylinder and a sealing cover. A hollow chamber for placing a sintering furnace main body is provided in the placing cylinder, and a plurality of screws are provided at the front and rear ends of the placing cylinder. The screw threads are inserted into the placing cylinder, and an abutment plate for abutting against the outer edge surface of the sintering furnace main body is installed at one end of the screw inserted into the placing cylinder. A hand wheel is fixed at one end of the screw located outside the placing cylinder. At the same time, the sealing cover cooperates with the side port of the placing cylinder, and two sliding rods are symmetrically fixed on both sides of the sealing cover. The sliding rods are inserted into the inside of both sides of the port of the placing cylinder, and an insulation cover for sealing the furnace mouth of the sintering furnace main body is fixed on the side of the sealing cover facing the placing cylinder, and a drawer plate slidably placed in the sintering furnace main body is horizontally installed at the lower side of the insulation cover. The placing device for a ceramic sintering furnace can be used for placing sintering furnaces of different specifications, and can avoid scalding of staff, and can quickly take out or place ceramics in the sintering furnace, which is easy to use.

[0004] However, the above patent has the following shortcomings: after the sintering furnace body is placed in the placement tube, there will be high temperature in the placement tube, which will affect the opening and closing of the sealing cover by the staff, and further affect the placement of ceramic materials in the sintering furnace; and it is not convenient to stably place the ceramic products placed on the placement plate, and there is a risk of the ceramic products tipping over during the pulling process. At the same time, it is not convenient to remove the high-temperature ceramic products from the placement plate. For this reason, we propose a placement device for a ceramic sintering furnace.
