Description

Technical Field

[0001] This utility model relates to the field of ceramic mold processing technology, and in particular to a uniform heating device for ceramic molds. Background Technology

[0002] In the ceramic production process, mold heating is a key step in ceramic shaping. The uniformity of heating directly affects the molding quality and performance of ceramic products. It is widely used in ceramic injection molding, high-temperature sintering and other processes. It is one of the core equipment for improving the precision of ceramic products and reducing the scrap rate. It has important application value in industrial ceramics, electronic ceramics and other fields.

[0003] Currently, most existing ceramic mold heating equipment adopts a fixed heating method, where the heating element and the mold are relatively stationary. This easily leads to uneven heating of different parts of the mold, resulting in defects such as cracks and shrinkage in ceramic products. At the same time, existing equipment lacks an effective mold positioning mechanism, which makes the mold prone to displacement during the heating process after placement, further aggravating the problem of uneven heating. Moreover, the positioning mechanism is difficult to adapt to molds of different sizes, has poor versatility, and cannot meet diverse production needs. In order to address this technical problem, this application proposes a uniform heating device for ceramic molds. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a uniform heating device for ceramic molds. This device achieves precise centering and fixing of molds of different sizes, preventing displacement during rotation. Simultaneously, the reverse uniform rotation structure ensures uniform heating of all parts of the mold, and the sealed design maintains temperature stability, effectively solving the problem of uneven heating and improving the molding quality and consistency of the mold.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A uniform heating device for ceramic molds includes a device body, a bracket fixedly connected to the lower side of the device body, a support rotatably connected to the upper side of the bracket, a heating plate provided on the outer wall of the support, a motor fixedly connected to the upper side of the device body, a gear disk fixedly connected to the output end of the motor, the gear disk being connected to the support via a first fixing rod, a pinion rotatably connected inside the device body, the pinion meshing with the outer edge of the gear disk, and a gear ring rotatably connected inside the device body, the gear ring meshing with the pinion, the gear ring being connected to the heating plate via a second fixing rod. The inner wall of the support is fixedly connected to a slide rail, a sliding block is slidably connected to the slide rail, a positioning rod is fixedly connected to the sliding block, a rotating plate is rotatably connected to the inner wall of the support, the rotating plate is rotatably connected to the sliding block through a guide rod, and a groove is provided on the outer wall of the support for the positioning rod to pass through and move radially therein.

[0006] Furthermore, one end of the guide rod is rotatably connected to the outer wall of the rotating plate, and the other end of the guide rod is rotatably connected to the outer wall of the sliding block.

[0007] Furthermore, a drive plate is fixedly connected to the bottom of the rotating plate.

[0008] Furthermore, the outer wall of the drive plate is provided with a recessed hole, and a spring and a movable ball are provided inside the lower side of the support. One end of the spring abuts against the support, and the other end of the spring abuts against the movable ball. The movable ball is elastically engaged with the recessed hole on the outer wall of the drive plate.

[0009] Furthermore, the output shaft of the motor is coaxially and fixedly connected to the center of the gear disc.

[0010] Furthermore, a rotating door is rotatably connected to the side wall of the device body via a hinge.

[0011] This utility model has the following beneficial effects: In this invention, the rotating drive plate drives the rotating plate and guide rod to move the sliding block along the slide rail, thereby driving the positioning rod to adjust radially to adapt to molds of different sizes. At the same time, the elastic cooperation between the spring and the movable ball can fix the positioning position, prevent the mold from shifting during the rotation heating process, ensure accurate heating position, reduce the problem of uneven local heating caused by shift, and improve the molding quality of the mold.

[0012] In this invention, the motor drives the gear disc, pinion and gear ring to mesh and transmit power, so that the support and heating plate rotate in opposite directions at a uniform speed, so that the mold and the heating plate form relative motion, allowing all parts of the mold to be evenly contacted with heat. At the same time, the closing of the rotating door can keep the internal temperature of the device stable, which solves the problem of uneven heating in traditional equipment and improves heating efficiency and mold forming consistency.

The gear disk 9 drives the support 11 to rotate around the axis of the bracket 10 through the first fixed rod 4. At the same time, the gear disk 9 meshes with the pinion 8, driving the pinion 8 to rotate. The pinion 8 then meshes with the gear ring 7, driving the gear ring 7 to rotate in the opposite direction. The gear ring 7 drives the heating plate 6 to rotate synchronously in the opposite direction through the second fixed rod 5, realizing the counter-uniform rotation of the support and the heating plate.

A positioning rod 12 is fixedly connected to the sliding block 15. A rotating plate 14 is rotatably connected to the inner wall of the support 11. The rotating plate 14 is rotatably connected to the sliding block 15 via a guide rod 16. One end of the guide rod 16 is rotatably connected to the outer wall of the rotating plate 14, and the other end of the guide rod 16 is rotatably connected to the outer wall of the sliding block 15. A drive plate 19 is fixedly connected to the bottom of the rotating plate 14. The outer wall of the 9 has a recessed hole. The lower side of the support 11 is provided with a spring 17 and a movable ball 18. One end of the spring 17 abuts against the support 11, and the other end of the spring 17 abuts against the movable ball 18. The movable ball 18 is elastically engaged with the recessed hole on the outer wall of the drive plate 19. The outer wall of the support 11 has a groove for the positioning rod 12 to pass through and move radially along it. The output shaft of the motor 1 is coaxially fixedly connected to the center of the gear plate 9. The side wall of the device body 3 is rotatably connected to the rotating door 2 by a hinge. Specifically, rotating the drive plate 19 can drive the rotating plate 14 to rotate synchronously. When the rotating plate 14 rotates, it pulls the sliding block 15 to slide laterally along the slide rail 13 through the guide rod 16. The sliding block 15 drives the positioning rod 12 to move radially along the slide groove on the outer wall of the support 11, thereby achieving the centering positioning of ceramic molds of different sizes. The spring 17 always applies an elastic force to the movable ball 18, causing the movable ball 18 to be inserted into the concave hole of the drive plate 19, thereby achieving the positioning of the drive plate 19. The rotating door 2 can close the device body 3 to ensure stable internal temperature.

[0018] Working principle: The device is used to heat ceramic molds to help them shape. During use, the bracket 10 is fixed to the lower side of the device body 3, and the upper side is rotatably connected to the support 11. The ceramic mold can be placed on the upper side. The heating plates 6 on all sides and the internal heating pipes heat and shape the center of the support 11. The rotating door 2 is closed to maintain a stable internal temperature. During use, the ceramic mold is placed in the middle of the outer wall of the support 11. The drive plate 19 at the bottom of the support 11 is rotated, which drives the rotating plate 14 fixedly connected to it to rotate. The upper and lower sides of the rotating plate 14 are rotatably connected to the guide rod 16. The other end of the guide rod 16 is rotatably connected to the upper side of the outer wall of the sliding block 15. The inner wall of the support 11 is fixedly connected to the slide rail 13. The sliding block 15 can slide laterally on its outer wall. The outer wall of the support 11 has a groove. During the sliding of the sliding block 15, the positioning rod 12 on the upper side of the outer wall passes through the groove to position the ceramic mold in the center and keep it in the center position to prevent it from shifting during rotation. The lower side of the support 11 is equipped with a spring 17 and a movable ball 18. The outer wall of the drive plate 19 has a concave hole, so that during the rotation of the drive plate 19, the movable ball 18 continuously fills the concave hole, increasing the rotation resistance and keeping the rotating plate 14 stable. The motor 1 on the upper side can drive the gear disk 9 in the middle of the device body 3 to rotate. The rotation of the gear disk 9 can drive the small gear 8 connected to the outer wall to rotate, thereby driving the gear ring 7 on the outer wall to rotate. The bottom of the gear ring 7 is connected to the heating plate 6 through the second fixing rod 5, guiding it to rotate in the middle of the device body 3. The bottom of the gear disk 9 drives the support 11 to rotate on the outer wall of the bracket 10 through the first fixing rod 4. The two sides rotate in opposite directions and rotate at a uniform speed to maintain uniform heating.
