Description

Technical Field

[0001] The utility model relates to the field of crucible bases, and particularly relates to a base for a sintered conical-bottom tungsten crucible. Background Art

[0002] The base for a sintered conical-bottom tungsten crucible is a device specially designed for the conical-bottom tungsten crucible product in a sapphire crystal growth furnace. Its structure mainly consists of a base, a conical bearing surface, and a central positioning hole. The base is in a circular body structure, and its diameter matches that of the tungsten crucible green compact, ensuring a stable mating relationship. A convex platform-shaped conical central positioning hole is provided at the center of the inner bottom surface of the base, which is used in cooperation with the convex platform on the upper surface of the tungsten crucible green compact to achieve precise positioning of the tungsten crucible.

[0003] However, the base for a sintered conical-bottom tungsten crucible has some disadvantages in the actual use process. First of all, there will inevitably be some debris or other substances generated during the experiment remaining on the base. These residues may affect the use effect of the base and even have an adverse impact on the experimental results. Secondly, the replacement process of the base is relatively cumbersome, requiring certain skills and patience, and it is necessary to avoid bringing the residues into the equipment to prevent damage to the equipment. Finally, the cleaning of the base is also a problem. Due to the shape and material characteristics of the base, some areas that are difficult to reach may not be thoroughly cleaned, and improper cleaning methods may also cause damage or deformation of the base. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a base for a sintered conical-bottom tungsten crucible, which can effectively solve the problems put forward in the background art.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A base for a sintered conical-bottom tungsten crucible, including a seat body. A notch is provided on the side wall of the seat body, and a protruding block is provided at the notch of the seat body. A pin hole is provided on the end face of the protruding block. The notch is blocked by inserting a plug rod into the pin hole. A placement groove is provided at the upper end of the seat body, and a stepped portion is provided in the groove of the placement groove. An isolation rack is placed on the stepped portion of the placement groove. A plurality of crucible limiting holes are provided on the end face of the isolation rack. The sintered conical-bottom tungsten crucible is restricted on the isolation rack and the seat body through the crucible limiting holes.

[0007] As a further preferred solution of the utility model, an installation rack is provided at the lower part of the side wall of the seat body, and a plurality of installation hole positions are provided on the end face of the installation rack. The installation rack is fixed by inserting bolts into the installation hole positions;

[0008] As a further preferred solution of the utility model, the stepped portion and the seat body are integrally designed, and the cross section of the stepped portion and the seat body is designed in an "L" shape, and the surfaces of the stepped portion and the seat body are smooth;

[0009] As a further preferred embodiment of the present utility model, the cross-section of the isolation frame is designed in a "T" shape and is adapted to the stepped portion and the seat body. The edge of the isolation frame is smoothly designed, and the width of the isolation frame is the same as the width of the notch;

[0010] As a further preferred embodiment of the present utility model, a plurality of crucible limiting holes are equidistantly distributed on the isolation frame. The diameter of the crucible limiting hole is adapted to the bottom protrusion of the sintered cone-bottom tungsten crucible, and the crucible limiting hole is also a chip removal through hole;

[0011] As a further preferred embodiment of the present utility model, the seat body and the protruding block are integrally designed, and the diameter of the pin hole is the same as the diameter of the crucible limiting hole.

[0012] Compared with the prior art, the present utility model has the following beneficial effects:

[0013] In the present utility model, when the base needs to be cleaned or maintained, the isolation frame can be very conveniently disassembled, so that the seat body and the isolation frame can be thoroughly cleaned, ensuring that the cleanliness and hygiene of the base meet the standards. In addition, this design also makes it very easy to replace the isolation frame of different specifications to adapt to sintered cone-bottom tungsten crucibles of different sizes or shapes, greatly enhancing the versatility and flexibility of the base, enabling it to adapt to more application scenarios.

[0014] Furthermore, since the isolation frame can be disassembled and replaced separately, when the isolation frame is damaged or worn, there is no need to replace the entire base, and only a new isolation frame needs to be simply replaced, which undoubtedly greatly reduces the maintenance cost. At the same time, the connection method between the seat body and the isolation frame is designed to be simple and reliable, effectively reducing the base failures caused by connection loosening or damage, and improving the overall stability and reliability of use.

[0015] In addition, the specially designed crucible limiting holes on the isolation frame can accurately ensure that the crucible is in the correct and stable position on the base, effectively preventing the crucible from shifting or toppling due to vibration or external force during the sintering process. This design not only helps to improve the sintering quality but also significantly reduces the risk of safety accidents that may be caused by the movement or toppling of the crucible, providing a safer and more reliable environment for the entire sintering process.

[0016] Finally, it is worth mentioning that there is a certain gap between the seat body and the isolation frame, and these gaps act as heat dissipation channels during actual use. They can effectively discharge the heat generated during the sintering process in a timely manner, reduce the temperature of the base and the crucible, thereby extending the service life of the base and ensuring the smooth progress of the entire sintering process.

[0022] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] As Figure 1 - Figure 4 shown, a base specially designed for a sintered conical bottom tungsten crucible, the base has a unique structure and comprehensive functions. Its main structure includes a seat body 1, and a notch 6 is ingeniously opened on the side wall of the seat body 1 to meet specific working requirements. At the position of the notch 6, a protruding block 2 is specially designed, and a pin hole 3 is opened on the end face thereof. This design enables us to insert a plug rod into the pin hole 3, thereby effectively blocking the notch 6 and ensuring the stability of the entire base.

[0024] At the upper part of the seat body 1, a placement groove 7 is opened, and a stepped portion 8 is further designed in this groove. This stepped portion 8 not only increases the layering and stability of the base, but more importantly, it provides an ideal support for placing the isolation frame 9. On the stepped portion 8, an isolation frame 9 is carefully placed, and a plurality of crucible limiting holes 10 are opened on the end face of this isolation frame 9. The function of these limiting holes is that they can accurately limit the sintered conical bottom tungsten crucible between the isolation frame 9 and the seat body 1, thereby ensuring the accuracy and stability of its position.

[0025] In order to facilitate the installation of the base, a mounting frame 4 is designed at the lower part of the side wall of the seat body 1. A plurality of mounting hole positions 5 are opened on the end face of this mounting frame 4, enabling us to conveniently fix it at the required position by inserting bolts.

[0026] It is worth mentioning that the stepped portion 8 and the seat body 1 are integrally designed, and their cross-sections present a unique "L" - shaped design, which is both beautiful and practical. At the same time, their surfaces are smooth, which not only improves the aesthetics but also reduces friction and wear.

[0027] The cross-section of the spacer 9 is designed in a "T" shape, which perfectly fits the stepped portion 8 and the base body 1. Its smooth edge design not only ensures aesthetics but also prevents possible scratches during use. In addition, the width of the spacer 9 is the same as the width of the notch 6, ensuring the stability and accuracy of its installation.

[0028] On the spacer 9, a plurality of crucible limiting holes 10 are equally distributed. The diameters of these limiting holes are adapted to the bottom protrusion of the sintered tapered-bottom tungsten crucible, which can not only ensure the stable placement of the crucible but also facilitate its removal and replacement. At the same time, these limiting holes also serve as chip removal through holes, effectively preventing the accumulation of debris generated during the sintering process.

[0029] Finally, the base body 1 and the protruding block 2 are also integrally designed, which not only improves the stability of the entire base but also simplifies the manufacturing process. The diameter of the pin hole 3 is the same as the diameter of the crucible limiting hole 10, ensuring the smooth and stable insertion of the insertion rod.

[0030] Usage process: Check the integrity of the base to ensure that components such as the base body 1, the protruding block 2, and the spacer 9 are complete and without obvious damage.

[0031] Next, place the base at the predetermined working position and fix the base in place using bolts through the mounting hole positions 5 on the mounting frame 4.

[0032] Then, place the spacer 9 on the stepped portion 8 of the base body 1, ensure that the edge of the spacer 9 is closely fitted with the edge of the stepped portion 8, and at the same time check whether the spacer 9 is placed stably.

[0033] Next, place the sintered tapered-bottom tungsten crucible on the spacer 9, ensure that the bottom protrusion of the crucible corresponds to the crucible limiting hole 10, and gently press the crucible to make it stably placed in the limiting hole.

[0034] At this time, if it is necessary to block the notch 6, the insertion rod can be taken out and inserted into the pin hole 3 until the other end of the insertion rod is closely fitted to the other side of the notch 6, thereby ensuring the stability of the entire base.

[0035] Finally, according to the requirements of the sintering process, perform the sintering operation. During the sintering process, the position and stability of the crucible can be regularly checked to ensure the smooth progress of the sintering process.

[0036] After sintering is completed, the insertion rod can be taken out first, and then the sintered tungsten crucibles can be taken out one by one. At the same time, the debris and residues on the base can be cleaned for the next use.

[0037] During the entire usage process, attention should be paid to the operation specifications to avoid unnecessary damage to the base and the crucible. At the same time, regular maintenance of the base can extend its service life and ensure the sintering quality.

[0038] It should be noted that in this text, relational terms such as first and second (No. 1, No. 2, etc.) are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variant are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device. Without further limitation, an element defined by the statement "including an..." does not exclude the presence of additional identical elements in the process, method, article or device including the element.

[0039] The foregoing has shown and described the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments, and what is described in the above embodiments and the specification is only to illustrate the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
