Description

Technical Field

[0001] The utility model relates to the technical field of mold furnaces, in particular to a furnace door structure of a mold furnace. Background Art

[0002] A heating furnace, also known as a mold furnace, is a device commonly used in metallurgy, mechanical processing and other scenarios for heating metals. During the processing of aluminum profiles, the mold needs to be heated to prevent the low temperature of the mold from affecting the plasticity of the aluminum profile, thereby facilitating the extrusion deformation of the material.

[0003] The mold heating furnace of the prior art generally includes a furnace body and a furnace door. In order to reduce the heat loss in the furnace body, the furnace door needs to have good heat insulation, so it is relatively thick. Because the furnace door is heavy, the existing furnace door often adopts the up and down sliding method to close it through manual hoisting or the front and back sliding method to close the furnace body. Both opening and closing need to rely on workers to manually operate. Since the furnace door is heavy, it is more laborious to open and close, and it is difficult to close and open manually. In addition, the mold frame of the existing aluminum profile mold heating furnace needs to be fixed on the mold furnace door, and the mold frame is pushed to slide through the furnace door. Therefore, the furnace door of the mold furnace must meet the following requirements: sufficient support and sealing. The existing mold furnace and the furnace door are often fixed by welding, but the mold frame and the furnace door are directly welded together, which is relatively bulky, difficult to carry and move, and inconvenient to replace later. A solution is proposed below to the above problems. Utility Model Content
