Although the static matrix layout increases the coverage area, there are energy blind spots between the grids. Especially in large-sized chambers, the problem of insufficient edge coverage is more prominent, resulting in insufficient curing of the edges and corners of the wax mold. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] The heating mechanism 2 includes a fixed frame 201, which is fixedly connected to the middle of the inner top wall of the chamber body 1. A slide rail 202 is fixedly connected to the bottom wall of the fixed frame 201. A gear 203 is rotatably connected to the top wall of the slide rail 202. A rack 204 is meshed with the front and rear sides of the outer wall of the gear 203. The rear rack 204 drives the front rack 204 to move synchronously in the opposite direction through the gear 203. A slider 205 is slidably connected to the bottom wall of the slide rail 202. The two sliders 205 move towards each other or in opposite directions along the slide rail 202. A square groove 206 is opened on the bottom wall of the slider 205. The slider 205 drives the infrared heating rod 207 to scan and heat horizontally. The infrared heating rod 207 is installed on the inner wall of the square groove 206. A drive assembly 208 is provided inside the chamber body 1.

[0034] The drive assembly 208 includes a motor 2081, which is fixedly connected to the middle of the top wall of the fixed frame 201. A crank 2082 is fixedly connected to the output end of the motor 2081. The motor 2081 drives the crank 2082 to rotate. A hollow block 2083 is fixedly connected to the top wall of the rear rack 204. The crank 2082 is slidably connected to the hollow block 2083. The crank 2082 moves inside the hollow block 2083, which drives the rear rack 204 to move left and right. The rack 204 is fixedly connected to the top wall of the slider 205. The output end of the motor 2081 passes through the middle of the top wall of the fixed frame 201.

[0035] Specifically, after starting motor 2081, the motor drives crank 2082 to rotate. The movement of crank 2082 inside hollow block 2083 drives the rear rack 204 to move left and right. The rear rack 204, through the transmission of gear 203, causes the front rack 204 to move in the opposite direction synchronously. This series of movements causes the two sliders 205 to move relative to each other on slide rail 202. Whether they are facing each other or in opposite directions, the movement of sliders 205 drives infrared heating rod 207 to perform horizontal scanning, thereby realizing a fast and uniform curing process for the wax model.

[0036] Reference Figure 3 and Figure 6 The rotating mechanism 3 includes a second motor 301, which is fixedly connected to the inner bottom wall of the chamber body 1. A shaped block 302 is fixedly connected to the output end of the second motor 301. The second motor 301 drives the shaped block 302 to rotate. A sliding column 303 is fixedly connected to the left side of the top wall of the shaped block 302. A fixed plate 304 is fixedly connected inside the chamber body 1. A rotating shaft 305 is fixedly connected to the left side of the top wall of the fixed plate 304. A rotating plate 306 is rotatably connected to the outer wall of the rotating shaft 305. The sliding column 303 drives the rotating plate. 306 rotates intermittently on the rotating shaft 305. The outer wall of the rotating plate 306 is provided with sliding grooves 307. The sliding column 303 is slidably connected to the sliding groove 307. The sliding column 303 on the irregular block 302 slides in the sliding groove 307 of the rotating plate 306. The top wall of the rotating plate 306 is fixedly connected to the disc 308. The disc 308 is rotatably connected to the middle of the inner wall of the chamber body 1. The rotating plate 306 drives the disc 308 to rotate in the chamber body 1. The output end of the motor 301 passes through the right side of the top wall of the fixed plate 304.

[0037] Specifically, motor 301 drives the irregular block 302 to rotate. The sliding column 303 on the irregular block 302 slides in the sliding groove 307 of the rotating plate 306. The sliding column 303 causes the rotating plate 306 to rotate intermittently on the rotating shaft 305. The rotating plate 306 then drives the disc 308 to rotate inside the chamber body 1. During the intermittent rotation, the wax mold on the disc 308 can fully receive the radiant heat from the infrared heating rod 207. This design avoids the problem of insufficient local heating time caused by continuous high-speed rotation and is particularly suitable for the uniform curing of wax molds with complex structures.

[0038] Reference Figure 1 and Figure 2A controller 4 is installed on the upper right side of the outer wall of the chamber body 1. The controller 4 is used to achieve precise control of temperature parameters. Multiple buttons 5 are installed at equal intervals on the right side of the outer wall of the controller 4.

The chamber door 6 is used to prevent heat loss during infrared heating. A handle 7 is installed on the front side of the outer wall of the chamber door 6. The handle 7 makes it easy for the operator to open or close the chamber door 6. Support feet 8 are fixedly connected to the four corners of the bottom wall of the chamber body 1. The support feet 8 are used to improve the stability of the chamber body 1. Universal wheels 9 are installed at the four corners of the bottom wall of the chamber body 1. The universal wheels 9 make it easy for the chamber body 1 to move and flexibly adjust the working position.

[0039] Specifically, controller 4 is used to achieve precise control of temperature parameters, button 5 is used to operate controller 4 to meet the needs of different wax mold curing processes, chamber door 6 is used to prevent heat loss during infrared heating and maintain stable temperature inside the chamber, handle 7 is used to facilitate the operator to open or close chamber door 6, support feet 8 are used to improve the stability of chamber body 1, and casters 9 are used to facilitate the movement of chamber body 1 and flexibly adjust working position.

[0040] Working principle: Start motor 2081, which drives crank 2082 to rotate. Crank 2082 moves inside hollow block 2083, causing rear rack 204 to move left and right. Rear rack 204 drives front rack 204 to move in opposite directions synchronously through gear 203, causing two sliders 205 to move in opposite directions along slide rail 202. Slider 205 drives infrared heating rod 207 to scan and heat horizontally, achieving rapid and uniform curing of wax mold.

[0041] Motor 2 301 drives the irregular block 302 to rotate. The sliding column 303 on the irregular block 302 slides in the sliding groove 307 of the rotating plate 306. The sliding column 303 drives the rotating plate 306 to rotate intermittently on the rotating shaft 305. The rotating plate 306 drives the disc 308 to rotate in the chamber body 1. The disc 308 drives the wax mold placed on it to rotate intermittently, so that each surface can fully receive the radiant heat of the infrared heating rod 207, avoiding insufficient local heating time due to continuous high-speed rotation. It is especially suitable for the uniform curing of wax molds with complex structures.
