Description

Technical Field

[0001] This utility model relates to the field of metal processing machine tool technology, specifically to a furnace door structure for a vacuum drying furnace. Background Technology

[0002] The furnace door structure of a vacuum drying oven is a key component to ensure a stable vacuum environment inside the oven and prevent outside air from entering. The furnace door needs to have good sealing performance to ensure that a stable vacuum environment can be maintained inside the oven during operation. This is usually achieved by using a multi-layer sealing structure, high-quality sealing rings or gaskets, and precision machining processes.

[0003] According to the description of a vacuum drying oven door published on the patent website (authorization announcement CN 219869041 U), "a vacuum drying oven door includes a furnace base, a drying oven box is provided on the upper part of the furnace base, the drying oven box is connected to the oven door through a rotating arm on one side, a set of locking modules is provided on all four sides of the oven door, the locking module includes a locking handle and a locking handwheel, the inner wall of the oven door is fixedly installed with reinforcing ribs, and reinforcing frames are provided on both sides of the reinforcing ribs."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] In use, this utility model opens and closes the furnace door by rotating the arm, and then presses the furnace door tightly with a locking handle and locking handwheel, ensuring a tight contact between the furnace door and the cavity. When the locking handwheel presses the furnace door, the sealing of the cavity is further improved by the first / second reinforcing U-frames on the inside of the cavity and the two sets of reinforcing openings on the inside of the furnace door. However, in actual use, the pressing operation using the locking handle and locking handwheel requires manual intervention, increasing the complexity of the operation. Operators need to be trained to master the correct operating method; otherwise, operational errors may occur. Furthermore, with frequent opening and closing of the furnace door, this manual operation method increases the required preparation time, thereby reducing work efficiency. Therefore, there is a need to improve the furnace door structure for a vacuum drying furnace. Utility Model Content

[0029] The closing and locking mechanism 2 includes a closing component 21 and a locking component 22, with the locking component 22 located at the top of the vacuum drying furnace body 1;

[0030] The closing assembly 21 includes a slot plate 211, which is fixedly connected to the right side of the vacuum drying furnace body 1. A connecting frame 212 is fixedly connected to the top of the slot plate 211, and a motor 213 is fixedly connected to the top of the connecting frame 212. A connecting rod 214 is fixedly connected to the output end of the motor 213. A pull rod 215 is rotatably connected to the end of the connecting rod 214 away from the motor 213. A connecting block 217 is rotatably connected to the bottom of the pull rod 215. A slider 216 is rotatably connected to the top of the connecting block 217. A sealing door 218 is fixedly connected to the front of the connecting block 217 to facilitate quick closure of the sealing door 218 and prevent leakage.

[0031] Furthermore, the groove plate 211 has a groove at the corresponding position of the slider 216, and the slider 216 is slidably connected in the groove, which makes it easier to restrict the movement of the slider 216 so that it can pull the connecting block 217 to move.

[0032] Furthermore, the connecting rod 214 is rotatably connected to the outside of the slot plate 211, and a slot is provided at the corresponding position of the vacuum drying furnace body 1 and the sealing door 218, and the sealing door 218 is inserted into the slot, which facilitates the movement of the pull rod 215.

[0033] Furthermore, the locking assembly 22 includes a fixing frame 221, which is fixedly connected to the top of the vacuum drying furnace body 1.

[0034] Furthermore, a groove is provided at the corresponding position of the fixed frame 226 and the inclined block 225, and the inclined block 225 is slidably connected in the groove. The left side of the inclined block 225 is closely attached to the right side of the sealing door 218, which facilitates a secondary locking function and prevents the sealing door 218 from being opened accidentally. Example

[0035] Regarding the issue of improving the sealing effect at the connection between the vacuum drying oven and the oven door based on existing technologies, please refer to [link / reference]. Figure 5 Furthermore, in conjunction with Embodiment 1, the sealing mechanism 3 includes a connecting strip 31, which is fixedly connected to the left side of the sealing door 218. A sealing ring 32 is fixedly connected to the left side of the connecting strip 31. A spring 33 is fixedly connected inside the vacuum drying oven body 1, and a sealing ring 34 is fixedly connected to the right side of the spring 33, which facilitates improving the sealing effect at the connection between the sealing door 218 and the vacuum drying oven body 1.

[0036] Furthermore, a groove is provided at the corresponding position of the vacuum drying furnace body 1 and the sealing ring 2 34, and the sealing ring 2 34 is slidably connected in the groove, and the sealing ring 1 32 and the sealing ring 2 34 abut against each other. A groove is provided at the corresponding position of the vacuum drying furnace body 1 and the connecting strip 31, and the connecting strip 31 is inserted into the groove, so that the sealing ring 1 32 and the sealing ring 2 34 can be squeezed against each other.

[0037] In actual operation, when the device is in use, firstly, when it is necessary to close the furnace door of the vacuum drying furnace 1, the closing locking mechanism 2 is used. At this time, the door is open and the slider 216 is located at the rightmost position in the corresponding groove of the slot plate 211, and the connection between the pull rod 215 and the connecting block 217 is located in the corresponding arc groove of the slot plate 211. At this time, by starting the motor 213, the motor 213 drives the connecting rod 214 to rotate clockwise, and then the connecting rod 214 pushes the pull rod 215 to move, so that the pull rod 215 pushes the connecting block 217 and the sealing door 218 to rotate along the arc groove of the slot plate 211. When the connection between the pull rod 215 and the connecting block 217 rotates to the vertical groove of the slot plate 211, the connecting rod 214 continues to rotate, thus pushing the connecting block 217 to move to the left. At the same time, during the leftward movement, the slider 216 is simultaneously driven along the arc groove of the slot plate 211. The vertical groove guides the movement, which in turn drives the sealing door 218 to gradually approach the vacuum drying furnace body 1, allowing it to be inserted into the vacuum drying furnace body 1. Before insertion, the sealing door 218 pushes the inclined block 225 upward. When the sealing door 218 reaches the leftmost end, under the elastic force of the spring 224, the left side of the inclined block 225 abuts against the right side of the sealing door 218, thus completing the secondary fixation of the sealing door 218. During the entire sealing and closing process, no manual intervention is required. At the connection between the vacuum drying furnace body 1 and the sealing door 218, the sealing mechanism 3, through the elastic force of the spring 33, pushes the sealing ring 32 and the sealing ring 34 to always abut against each other. Meanwhile, the connecting strip 31 is inserted into the corresponding groove of the vacuum drying furnace body 1, thereby further improving the connection effect between the vacuum drying furnace body 1 and the sealing door 218, thus preventing leakage.
