Description

Technical Field

[0001] This utility model relates to the field of electronic equipment technology, specifically to a sintering device. Background Technology

[0002] Dental sintering equipment is the core equipment in the processing of dental prostheses. It is mainly used for high-temperature sintering and molding of materials such as zirconia and metal alloys. Through a precision temperature control system (the maximum temperature can reach 1600℃) and a programmed heating curve, the equipment can achieve material densification, ensuring the strength, precision and biocompatibility of the prostheses. Modern sintering furnaces have vacuum or inert gas protection functions to prevent material oxidation and support rapid cooling (some models). It is suitable for the fabrication of all-ceramic crowns, bridges, implants and other restorations. It has the characteristics of high automation, good stability, energy saving and environmental protection, and is an important link in digital dental processing.

[0003] In the existing technology, the polished dentures are placed into a sintering equipment for sintering. The support frame in the sintering equipment descends, places the dentures into a receiving box, and then places the receiving box onto the support frame. Subsequently, the support frame rises into the interior of the sintering equipment for heating and sintering. After heating and sintering, because the receiving box is heated at high temperature, tools are needed to transfer the receiving box when it is removed from the sintering equipment, which is a cumbersome operation.

[0004] Therefore, a sintering device is proposed. Utility Model Content

The clamping mechanism includes a horizontal plate mounted on the base, a vertical plate mounted on the horizontal plate, two movable blocks slidably mounted on the vertical plate, each movable block having a clamping arm mounted on it, and an arc-shaped groove formed on the inner surface of each clamping arm, both arc-shaped grooves contacting the outer surface of the receiving box.

A U-shaped frame is installed on the two support plates, and a blower assembly is installed on the U-shaped frame. The blower assembly is adapted to the receiving box.

[0014] Compared with the prior art, the beneficial effects of this utility model are: This invention, through the arrangement of a reciprocating screw, a moving block, a vertical plate, a first forward and reverse motor, and a clamping arm, allows the clamping arm to move closer to the housing after the dentures have been sintered inside the housing. Then, the first forward and reverse motor moves the transmission rods on both sides toward the center, thereby conveniently and automatically removing the housing from the support frame. This avoids the inconvenience of manually removing the housing with tools, which can also lead to burns if the housing is not held securely.

[0015] This invention, through the arrangement of a support plate, a U-shaped frame, and a blower assembly, allows for continuous airflow to the receiving box after it has been removed using a clamping arm. This increases the airflow within the receiving box, thereby cooling the dentures inside and increasing their heat dissipation rate without damaging them. Attached Figure Description

An arc-shaped groove is formed on the inner surface of each clamping arm 53, and both arc-shaped grooves contact the outer surface of the receiving box 4. By utilizing the arc-shaped grooves on the clamping arms 53, the receiving box 4 can be effectively clamped and fixed, avoiding the inconvenience of manually removing the receiving box 4 with tools, and the risk of burns due to unstable handling.

[0019] Furthermore, the drive mechanism includes a mounting hole 6. The mounting hole 6 is provided on the upright plate 51. A drive shaft 61 is rotatably mounted on the inner wall of the top side of the mounting hole 6. A strip plate 62 is mounted on the drive shaft 61.

A sliding block 65 is mounted on each of the two transition shafts 64. The two sliding blocks 65 are respectively mounted on two movable blocks 52. A first forward and reverse motor 67 is bolted to the inner wall of the bottom side of the mounting hole 6. The output shaft of the first forward and reverse motor 67 is mounted on the bottom end of the drive shaft 61. A limit hole 66 is provided on the upright plate 51. The sliding block 65 is slidably mounted on the inner wall of the limit hole 66.

[0020] Furthermore, the translation mechanism includes a mounting groove 7. A mounting groove 7 is formed on the horizontal plate 5. A moving block 71 is slidably mounted on the inner wall of the mounting groove 7. The moving block 71 is mounted on the bottom side of the vertical plate 51. A reciprocating screw 72 is threaded onto the moving block 71. The reciprocating screw 72 is rotatably mounted inside the mounting groove 7. A mounting bracket 73 is mounted on one end of the horizontal plate 5. A second forward / reverse motor 74 is bolted to the mounting bracket 73. The output shaft of the second forward / reverse motor 74 is mounted on one end of the reciprocating screw 72. The second forward / reverse motor 74 drives the reciprocating screw 72 in the mounting groove 7 to rotate. The reciprocating screw 72 drives the moving block 71 to slide to the left. The moving block 71 drives the vertical plate 51 to slide to the left, thereby... It can easily move the clamping arms 53 on the upright plate 51 to both sides of the receiving box 4. After the clamping arms 53 clamp and fix the receiving box 4, the second forward and reverse motor 74 drives the receiving box 4 to move to the right, so that the receiving box 4 can be automatically removed. The first forward and reverse motor 67 drives the drive shaft 61 to rotate, the drive shaft 61 drives the strip plate 62 to rotate, the strip plate 62 drives the transmission rod 63 to rotate, the transmission rod 63 drives the adapter shaft 64 to move towards the middle, the adapter shaft 64 drives the sliding block 65 to move, the sliding block 65 drives the movable block 52 to move, and the movable block 52 drives the clamping arms 53 to move towards the middle, so that the receiving box 4 can be easily clamped in the arc grooves on the two clamping arms 53.

[0021] Furthermore, the cooling mechanism includes two support plates 8, which are respectively installed on both sides of the horizontal plate 5. A U-shaped frame 81 is installed on the two support plates 8, and a blower assembly 82 is installed on the U-shaped frame 81. The blower assembly 82 is adapted to the receiving box 4. When the receiving box 4 moves to the right and is directly below the blower assembly 82, the receiving box 4 stops moving. At this time, the switch on the blower assembly 82 is turned on, and the blower assembly 82 continuously blows air into the receiving box 4, thereby increasing the airflow in the receiving box 4 to cool down the dentures inside the receiving box 4. This can increase the heat dissipation speed of the dentures without damaging them.

[0022] The working principle is as follows: After the receiving box 4 is sintered in the support frame 3, it is released downwards. Then, the switch of the second forward and reverse motor 74 on the mounting frame 73 is turned on. The second forward and reverse motor 74 drives the reciprocating screw 72 in the mounting groove 7 to rotate. The reciprocating screw 72 drives the moving block 71 to slide to the left. The moving block 71 drives the upright plate 51 to slide to the left. The upright plate 51 drives the clamping arm 53 to slide to the left. When the arc groove on the clamping arm 53 moves to both sides of the receiving box 4, the switch of the first forward and reverse motor 67 is turned on. The first forward and reverse motor 67 drives the drive shaft 61 to rotate. The drive shaft 61 drives the strip plate 62 to rotate. The strip plate 62 drives the transmission rod 63 to rotate. The transmission rod 63 drives the adapter shaft 64 to move towards the center. The adapter shaft 64 drives the sliding block 65 to move. The sliding block 65 drives the movable block 52 to move. The movable block 52 drives the clamping arm 53 to move towards the center, so that the receiving box 4 can be easily clamped in the arc groove on the two clamping arms 53, thus facilitating the automatic removal of the receiving box 4 from the support frame 3. When the receiving box 4 moves to the right and is directly below the air blowing assembly 82, the receiving box 4 stops moving. At this time, the switch on the air blowing assembly 82 is turned on, and the air blowing assembly 82 continuously blows air into the receiving box 4, thereby increasing the air flow in the receiving box 4 to cool down the dentures inside the receiving box 4.
