Description

Technical Field

[0001] The invention relates to the technical field of quartz boat molds, in particular to a quartz boat ceramic rapid prototyping and demoulding integrated device. Background Art

[0002] Quartz is one of the main rock-forming minerals, generally referring to low-temperature quartz. It is the most widely distributed mineral in the quartz family. In a broad sense, quartz also includes high-temperature quartz and coesite. Its main component is SiO2, which is colorless and transparent. It often contains a small amount of impurities, turning it into translucent or opaque crystals with a hard texture. Quartz boat, also known as quartz glass, is a laboratory and industrial equipment made of high-purity quartz material, containing silicon dioxide substances such as crystal and silica. Generally, the production of some quartz products can be completed by carving or casting. The casting process requires the use of molds.

[0003] In the existing technology, the casting of quartz boats requires the use of molds. The quartz glass is placed in the mold and heated to a molten state. After cooling and solidification, it forms a target shape. The existing quartz boat molding process mostly uses graphite molds. Since the surface of the graphite mold has strong adsorption properties, the quartz glass is easy to stick to the mold after cooling and solidification, resulting in difficulty in demolding. Although the existing process sprays a release agent before the mold is used to assist in demolding the quartz boat, it is difficult to effectively demold the corners of the quartz boat relying solely on the release agent. If forced demolding is performed, the quartz boat may be damaged, affecting the product yield and performance. There are obvious limitations in actual production applications. Summary of the Invention

[0010] Preferably, two groups of slots are provided on the surface of the fixed plate, and dual-axis motors are fixedly installed at the center positions of the inner walls of the two groups of slots, and the output shafts at both ends of the dual-axis motors are connected to threaded rods, and the U-shaped seat is threadedly sleeved on the outer wall of the threaded rod.

[0011] Preferably, the lower surface of the turntable is provided with an electric telescopic rod installed inside the base, the output end of the electric telescopic rod is fixedly connected to a movable rod, the upper surface of the turntable is fixedly connected to a fixed block, and the movable rod is sleeved on the inner wall of the fixed block.

[0012] Preferably, a spiral groove is formed on the inner wall of the fixed block, and a protrusion is fixedly connected to the surface of one side of the top end of the movable rod, and the protrusion is clamped on the inner wall of the spiral groove.

[0013] Preferably, a positioning frame is fixedly connected to the top of the base, a mounting groove is provided at the center of the top of the base, and the vibration block contacts the bottom of the mounting groove.

[0014] In summary, the present invention mainly has the following beneficial effects:

[0015] 1. The present invention drives the stop block to reciprocate by a turntable in the transmission assembly, and utilizes the geometric characteristics of the inclined surface profile on the stop block to convert the rotational motion of the turntable into linear reciprocating motion. That is, when the turntable drives the stop block to rotate, the inclined surface of the stop block forms rolling contact with the transmission rod, pushing the transmission rod to perform linear motion in the vertical direction, and then cooperating with the push block to push the push rod to move. The push rod drives the vibration block to generate high-frequency vibration, thereby achieving directional vibration of the corners of the lower mold, effectively destroying the adhesion between the quartz boat and the mold, to a certain extent preventing damage to the quartz boat during demolding, and improving the demolding efficiency. Since the stop block adopts a gradient inclined surface design with a low inner side and a high outer side, the initial and subsequent contact heights of the transmission rod and the stop block can be changed by adjusting the installation position of the vibration block. When the transmission rod contacts the lowest point of the stop block, the transmission rod movement stroke is the longest, and the vibration frequency and vibration intensity are low at this time. When the transmission rod contacts the higher position of the stop block, the transmission rod movement stroke is shortened, and the vibration frequency and vibration intensity are correspondingly increased. This facilitates the adjustment of vibration efficiency for molds of different shapes and improves the demolding speed.

[0016] 2. The present invention drives the U-shaped seat to move linearly along the slot on the fixed plate through the dual-axis motor in the adjustment assembly and the threaded rod, so as to quickly adjust the lateral position of the vibration block, ensure that the vibration block is accurately aligned with the edge corner of the lower mold inside the installation slot, and improve the flexibility of the structure. Moreover, since the size of the second gear is smaller than that of the first gear, when the U-shaped seat moves, the second gear and the rack cooperate with each other to enable the first gear to synchronously drive the connecting block to rotate, thereby achieving angle adjustment of the vibration block and ensuring that the vibration block can maintain the optimal contact angle with the edge corner of the lower mold inside the installation slot at any position, thereby improving the vibration effect, reducing the possibility of adhesion during demoulding, and improving the vibration efficiency and demoulding efficiency to a certain extent.

[0029] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be understood as limiting the present invention.

[0030] The following describes an embodiment of the present invention based on its overall structure.

[0031] A quartz boat ceramic rapid prototyping and demoulding integrated device, such as Figures 1-11 As shown, it includes a substrate 1, four groups of support rods 11 are fixedly connected to the upper surface of the substrate 1, a cylinder 5 is fixedly installed at the center position of the top of the four groups of support rods 11, a base 2 is fixedly connected to the center position of the upper surface of the substrate 1, a lifting plate 4 is sleeved on the outer wall of the four groups of support rods 11, an upper mold 41 is movably installed on the lower surface of the lifting plate 4, and a lower mold 3 is movably installed on the upper surface of the base 2. The cylinder 5 cooperates with the lifting plate 4 to drive the upper mold 41 to descend, and the quartz boat can be formed by the mutual cooperation of the upper mold 41 and the lower mold 3;

[0032] For example, a fixing plate 7 is fixedly connected to the interior of the base 2, and four sets of vibration blocks 8 are provided above the fixing plate 7 to vibrate the lower mold 3. The vibration blocks 8 can vibrate the mounting groove 21 to facilitate the subsequent demolding of the quartz boat inside the lower mold 3.

[0033] For example, two sets of adjustment components for adjusting the angle and position of the vibration block 8 are movably mounted on the upper surface of the fixed plate 7, so as to facilitate vibration operation on molds of different sizes. A transmission component for driving the vibration block 8 is provided on the lower surface of the fixed plate 7, and power can be provided to the vibration block 8 through the transmission component.

[0034] Exemplarily, the transmission assembly includes a turntable 61 located below the fixed plate 7, and the adjustment assembly includes a U-shaped seat 91 located on the upper surface of the fixed plate 7. Two groups of symmetrical blocks 62 are fixedly connected to the upper surface of the turntable 61. A transmission rod 66 is movably inserted into the surface of the U-shaped seat 91. The top of the transmission rod 66 is fixedly connected to a push block 67 that contacts the bottom end of the push rod 97. A rubber pad is installed on the upper surface of the push block 67. When the block 62 rotates, the transmission rod 66 can be pushed to move upward. The transmission rod 66 cooperates with the push block 67 to squeeze the push rod 97. The push rod 97 can push the vibration block 8 to move, vibrate the lower mold 3, and facilitate the subsequent demolding of the quartz boat.

[0035] See Figure 3 、 Figure 4 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 11 It can be seen that the inner wall of the U-shaped seat 91 is connected to a connecting block 92 through a damping shaft, one end of the connecting block 92 is fixedly connected to a spring 96, and the other end of the spring 96 is fixedly connected to the vibration block 8. A push rod 97 in contact with the vibration block 8 is movably sleeved on the inner wall of the connecting block 92. The position of the vibration block 8 can be adjusted through the U-shaped seat 91, so that it is suitable for lower molds 3 of different sizes. By setting the spring 96, the vibration block 8 can be buffered.

[0036] See Figure 5 、 Figure 7 、 Figure 8 As can be seen, the stop block 62 is tilted from the inside to the outside and from the front to the back, and the front end is relatively protruding. By setting the stop block 62 to a special shape, the initial and subsequent contact heights between the transmission rod 66 and the stop block 62 can be changed, thereby facilitating the adjustment of the vibration efficiency for molds of different shapes, with strong adaptability and high flexibility.

[0037] For example, since the connecting block 92 and the vibration block 8 are both arranged at an angle, when the transmission assembly drives the vibration block 8 to vibrate, it is convenient for the vibration block 8 to align with the corners of the lower mold 3 inside the installation groove 21, thereby facilitating the subsequent vibration demolding of the lower mold 3.

[0038] See Figure 3 、 Figure 4 、 Figure 7 、 Figure 8 、 Figure 9 It can be seen that the adjustment component also includes a first gear 93 rotatably connected to the outer wall of one side of the U-shaped seat 91, and the first gear 93 is fixedly connected to the connecting block 92 through a shaft. A second gear 94 rotatably connected to the side wall of the U-shaped seat 91 is engaged below the first gear 93, and two sets of racks 95 meshing with the second gear 94 are fixedly connected to the upper surface of the fixed plate 7. When the U-shaped seat 91 moves, the first gear 93 is driven to rotate by the engagement of the second gear 94 with the rack 95. The first gear 93 drives the connecting block 92 to rotate through the shaft to achieve angle adjustment of the vibration block 8, so that the vibration block 8 always maintains the best contact angle with the corners of the lower mold 3 inside the mounting groove 21, which is convenient for subsequent demoulding and prevents adhesion at the corners.

[0039] See Figure 3 、 Figure 4 、 Figure 7 、 Figure 8 As can be seen, the surface of the fixed plate 7 is provided with two sets of slots 71. A dual-axis motor 98 is fixedly mounted at the center of the inner wall of each set of slots 71. The output shafts of the dual-axis motor 98 are connected to threaded rods 99. A U-shaped seat 91 is threadedly sleeved onto the outer wall of the threaded rod 99. Both sides of the U-shaped seat 91 are fixedly connected to limit blocks 911 that contact the upper surface of the fixed plate 7. The threaded rods 99 and the transmission rods 66 are arranged in an interlaced manner. The dual-axis motor 98 drives the threaded rods 99 to rotate. The position of the U-shaped seat 91 can be adjusted under the action of the threaded rods 99, thereby facilitating the change of the position of the vibrating block 8. The limit blocks 911 cooperate with the slots 71 to limit the position of the U-shaped seat 91. (A wireless control module is installed inside the base 2, which can control the activation of the dual-axis motor 98.)

[0040] See Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 It can be seen that the lower surface of the turntable 61 is provided with an electric telescopic rod 64 installed inside the base 2, and the output end of the electric telescopic rod 64 is fixedly connected to a movable rod 65, and the upper surface of the turntable 61 is fixedly connected to a fixed block 63, and the movable rod 65 is sleeved on the inner wall of the fixed block 63, and a spiral groove 631 is provided on the inner wall of the fixed block 63. A protrusion 651 is fixedly connected to the surface of one side of the top of the movable rod 65, and the protrusion 651 is clamped on the inner wall of the spiral groove 631. The movable rod 65 is driven up and down by the electric telescopic rod 64, and the movable rod 65 drives the turntable 61 to rotate through the protrusion 651 and the spiral groove 631. Since the movable rod 65 moves back and forth, it can drive the turntable 61 to rotate back and forth.

[0041] See Figure 1 and Figure 2It can be seen that a positioning frame 22 is fixedly connected to the top of the base 2, and a mounting groove 21 is provided at the center of the top of the base 2. The lower mold 3 can be installed through the mounting groove 21. By setting the mounting groove 21, the lower mold 3 can be positioned to facilitate installation. A glass window is provided on the surface of the base 2, through which the position of the vibration block 8 can be checked.

[0042] Exemplarily, the vibration block 8 contacts the bottom end of the installation groove 21 . When the vibration block 8 vibrates, the vibration can be transmitted to the lower mold 3 through the installation groove 21 , so as to facilitate vibration demoulding of the lower mold 3 .

[0043] The working principle of the present invention is as follows: the quartz boat can be shaped by cooperating with the lower mold 3 through the upper mold 41. When the quartz boat is cooled and formed, the quartz boat is demoulded. The movable rod 65 is driven by the electric telescopic rod 64 to move back and forth on the inner wall of the fixed block 63. Under the mutual cooperation of the spiral groove 631 and the protrusion 651, the turntable 61 can be driven to rotate back and forth. When the turntable 61 rotates, the block 62 abuts against the transmission rod 66. When the block 62 rotates, the transmission rod 66 can be driven to rise and fall. At this time, the transmission rod 66 cooperates with the push block 67 to push the push rod 97 to move. Under the buffering action of the spring 96, the push rod 97 drives the vibration block 8 to vibrate the corners of the lower mold 3 in the installation groove 21, so as to facilitate subsequent demoulding.

[0044] Furthermore, after the upper mold 41 and the lower mold 3 are replaced, the position and angle of the vibration block 8 can be adjusted by the adjustment component according to the position of the mold, and the dual-axis motor 98 is started. The dual-axis motor 98 drives the threaded rod 99 to rotate. At this time, the U-shaped seat 91 moves under the drive of the threaded rod 99, thereby changing the position of the vibration block 8 to facilitate its application to molds of different sizes. During the movement of the U-shaped seat 91, the second gear 94 engages with the rack 95 to drive the first gear 93 to rotate, thereby driving the connecting block 92 to rotate, thereby adjusting the angle of the vibration block 8, ensuring that the vibration block 8 can maintain the optimal contact angle with the corners of the lower mold 3 inside the mounting groove 21 at any position, and vibrating the lower mold 3 to facilitate subsequent demoulding and prevent adhesion.

The specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.
