[0002] Quartz crucible is a vessel made of high-purity quartz sand. It has the advantages of high purity, strong temperature resistance, large size and high precision, good thermal insulation, energy saving, stable quality, etc. It is widely used.

[0003] During the production process, the quartz crucible mold is a key tool in making quartz crucibles. The crucible blank is typically created using gelcasting. A prepared quartz slurry is poured into the mold cavity, where the monomer molecules in the slurry undergo a polymerization reaction to form a gel network, solidifying the quartz slurry into a crucible blank. This is then dried to produce the quartz crucible. The formed quartz crucible needs to be removed from the mold. The current demolding method involves manually striking and rotating the mold, loosening the loose sand between the mold and the quartz crucible through vibration and gravity, allowing the quartz crucible to gradually escape from the mold.

[0004] Therefore, there are problems such as long demoulding time and inconvenience in demoulding. At the same time, some residues will stick to the inside of the mold, making it difficult to clean, thereby affecting the quality of the finished quartz crucible. Utility Model Content

Vertical plates 5 corresponding to the two through holes 4 are provided above the lower mold 2, and a limiting rod 6 is inserted between the vertical plate 5 and the corresponding through holes 4; a through hole 2 11 is provided below the lower mold 2, an electric telescopic rod 12 is connected to the bottom of the lower mold 2, and the lower end of the electric telescopic rod 12 is connected to a horizontal plate 13, and a push rod 14 inserted in the through hole 2 11 is provided above the horizontal plate 13, and the highest height of the push rod 14 is in contact with the upper mold 1.

[0031] Through the above structure, after the upper mold 1 is fitted and inserted into the lower mold 2, the position of the upper mold 1 is fixed by inserting the limit rod 6 into the through hole 4 thereon. By controlling the electric telescopic rod 12, the push rod 14 is made level with the inner wall of the bottom of the lower mold 2. The gap between the upper mold 1 and the lower mold 2 constitutes a chamber. The configured quartz slurry is poured into the upper part of the chamber. The monomer molecules in the slurry will undergo polymerization reaction to form a gel network, so that the quartz slurry is solidified into a crucible blank. After drying, a quartz crucible is obtained. After the upper mold 1 is removed, the formed quartz crucible is pushed into the lower mold 2 by controlling the electric telescopic rod 12 to push the push rod 14 out of the quartz crucible. Demolding is convenient and efficient.

[0032] An L-shaped base 7 is provided under the lower mold 2, and a motor 8 is fixed on the vertical side of the base 7. The output end of the motor 8 is connected to a connecting piece 9. The lower mold 2 is connected to the connecting piece 9. The corners of the outer wall of the lower mold 2 are all rounded structures. During use, the outer wall of the lower mold 2 is rounded to avoid scratches. A nozzle 10 is provided above the horizontal side of the base 7. The nozzle 10 is an umbrella-shaped structure, and the center is concentric with the center of the lower mold 2.

[0033] Through the above structure, the starting motor 8 can control the rotation of the lower mold 2 so that the cavity of the lower mold 2 faces downward, and is flushed by the nozzle 10 so that the internal residue can be easily cleaned and dried for the next use, avoiding affecting the quality of the finished quartz crucible.

[0036] Based on the first embodiment, please refer to the attached Figure 4 and attached Figure 5

[0037] Both ends of the limiting rod 6 are provided with threads, and nuts 15 are threadedly sleeved on both ends of the limiting rod 6 .

[0038] Through the above structure, both ends of the limiting rod 6 are limited by the sleeve nuts 15 to prevent the limiting rod 6 from being separated from the through hole 4.

[0039] The connecting member 9 is a cross-shaped structure, and the other end of the connecting member 9 is connected to a cross-shaped rubber sheet 16. The area of ​​the rubber sheet 16 is larger than that of the connecting member 9. The side wall of the lower mold 2 is provided with a cross-shaped groove 17 that cooperates with the connecting member 9 and the rubber sheet 16.

[0040] Through the above structure, the lower mold 2 is pressed and sleeved on the outside of the connecting piece 9. The lower mold 2 is detachable for easy replacement to be suitable for the production of quartz crucibles of different shapes.

[0041] The specific method of use is as follows: after the upper mold 1 is fitted into the lower mold 2, the position of the upper mold 1 is fixed by inserting the limit rod 6 into the through hole 4 thereon. The two ends of the limit rod 6 are limited by the sleeve nuts 15 to prevent the limit rod 6 from being separated from the through hole 4. By controlling the electric telescopic rod 12, the push rod 14 is made level with the bottom inner wall of the lower mold 2, and the lower mold 2 is pressed and sleeved on the outside of the connecting piece 9 so that the lower mold 2 can be controlled to rotate by the motor 8. In the initial state, the mold is in a vertical state, and the gap between the upper mold 1 and the lower mold 2 constitutes a cavity. The configured stone is poured from the top of the cavity. The monomer molecules in the slurry will undergo polymerization reaction to form a gel network, thereby solidifying the quartz slurry into a crucible blank. After drying, a quartz crucible is obtained. After removing the upper mold 1, the formed quartz crucible is pushed into the lower mold 2 by controlling the electric telescopic rod 12 to push the push rod 14 out of the lower mold 2 to eject the quartz crucible. The demoulding is convenient and efficient. After taking out the quartz crucible, starting the motor 8 can control the rotation of the lower mold 2 so that the cavity of the lower mold 2 faces downward. The nozzle 10 is used for flushing so that the internal residue can be easily cleaned off. After drying, it can be used next time to avoid affecting the quality of the finished quartz crucible.
