Description

Technical Field

[0001] This utility model relates to the technical field of vacuum sintering equipment accessories, specifically a split-type carbon-carbon composite crucible for vacuum sintering. Background Technology

[0002] In the vacuum sintering process, the crucible is a key container for holding materials, and its performance plays a crucial role in the sintering effect.

[0003] Currently, most traditional crucibles are one-piece structures, which have revealed numerous problems during use. For example, they are difficult to adapt to new process requirements through structural modifications, resulting in low flexibility. After sintering, the material may adhere to the inner wall of the crucible, making it difficult to remove the material completely from a one-piece crucible. This often requires forced separation, which can easily damage the crucible and potentially harm the material, affecting product quality. Furthermore, if a part of a one-piece crucible is damaged after long-term use, the entire crucible needs to be replaced, leading to high costs. Additionally, existing crucible materials (graphite) have limitations in terms of weight and mechanical strength, failing to meet the demands of increasingly complex vacuum sintering processes.

[0004] A split-type carbon-carbon composite crucible for vacuum sintering is proposed to address the problems mentioned above. Utility Model Content

[0005] The purpose of this invention is to provide a split carbon-carbon composite crucible for vacuum sintering, in order to solve the problems mentioned in the background art, such as the difficulty in adapting to new process requirements through structural modification, low flexibility, and the difficulty in completely removing the material from an integrated crucible after sintering due to the possibility of the material adhering to the inner wall of the crucible. This often requires the use of external force to forcibly separate the material, which can easily damage the crucible and may also damage the material, affecting product quality. Moreover, if a part of the integrated crucible is damaged after long-term use, the entire crucible needs to be replaced, resulting in high costs.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a split-type carbon-carbon composite crucible for vacuum sintering, including a bottom plate;

[0007] Also includes:

[0008] The base plate has a first side plate symmetrically arranged on both sides of the top, and a second side plate symmetrically arranged on the other two sides of the top, and a first step is provided at the bottom of the first side plate, and positioning holes are symmetrically opened through both sides of the first side plate.

[0009] Among them, a second step is provided below each of the two second side plates, and the width of the first step and the second step is 3mm. Limiting holes are symmetrically opened through both sides of the second side plate, and positioning bolts are provided inside the positioning holes and the limiting holes.

[0010] Connecting posts are provided at the angles between the two first side plates and the two second side plates, and connecting grooves are provided at the four corners of the base plate. The connecting posts are adapted to the connecting grooves. The connecting posts are provided with first threaded holes and second threaded holes on the sides near the first and second side plates, respectively, and the positioning bolts are threaded to the first threaded holes and second threaded holes.

[0011] Preferably, a support plate is fixedly installed at the bottom of the connecting column, and a connecting block is fixedly installed at the bottom of the support plate. A placement groove is provided at the top of the connecting column, and the connecting block is adapted to and connected to the placement groove.

[0012] Preferably, a support groove is provided through the bottom of each of the two first side plates and the two second side plates, and a positioning component is provided inside the support groove.

[0013] Preferably, the positioning assembly includes two sets of positioning blocks fixedly installed on the outer side of the base plate, and the top of the positioning blocks is symmetrically provided with connecting holes. The two first side plates and the two second side plates are fixedly installed with support frames above the positioning blocks. The support frames are symmetrically provided with insert rods inside, and the tops of the two insert rods are fixedly installed with connecting frames. The insert rods are adapted to connect with the connecting holes.

[0014] Preferably, a fixing block is symmetrically installed at the bottom of the positioning block between the two insert rods, and a positioning rod is slidably connected inside the fixing block. A positioning groove is opened on one side of the insert rod, and the positioning rod is engaged with the positioning groove.

[0015] Preferably, a telescopic spring is fitted on the outer side of each of the two positioning rods, and one end of the telescopic spring is fixedly connected to the fixing block, and a push block is fixedly installed on the other end of the telescopic spring, and the push block is fixedly connected to the positioning rod.

[0016] Preferably, all components are made of carbon-carbon composite material.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: This split-type carbon-carbon composite crucible for vacuum sintering has a split design that allows for easy separation of the crucible body from the material after sintering, thus enabling complete removal of the material. This avoids damage to the material and crucible caused by forced material removal, improving product quality and production efficiency. Furthermore, when the crucible is partially damaged, only the damaged part needs to be replaced, rather than the entire crucible, greatly reducing maintenance costs. The specific details are as follows:

[0018] 1. The crucible can be assembled from two first side plates, two second side plates, and a bottom plate. The crucibles can be stacked. When assembling the first and second side plates with the bottom plate, the bottom plate is placed on the first and second steps, and the connecting post is set in the connecting groove at the corner of the bottom plate. Then, the positioning bolts are passed through the positioning holes and the limiting holes respectively, so that several positioning bolts are screwed into the first threaded hole and the second threaded hole respectively, thereby completing the overall assembly. After sintering, the first and second side plates can be disassembled to facilitate the removal of materials. After sintering, the crucible body can be easily separated from the materials, so that the materials can be completely removed. This avoids damage to the materials and crucible caused by forced material removal, improves product quality and production efficiency, and when the crucible is partially damaged, only the damaged part needs to be replaced instead of replacing the entire crucible, which greatly reduces maintenance costs.

[0019] 2. After the first and second side plates are assembled, the positioning block on the base plate can extend out of the support groove. Then, two insert rods can be inserted into the support frame, and then the insert rods can be inserted into the connecting holes. Since the bottom end of the insert rod is hemispherical, the bottom end of the insert rod can push the positioning rod to move through the curved surface, so that the positioning rod moves and stretches the telescopic spring. Then the insert rod is inserted into the connecting frame and abuts against the support frame. At this time, the positioning rod can be aligned with the positioning groove. Under the action of the telescopic spring, the positioning rod and the positioning groove are engaged, thereby further positioning the first and second side plates and the base plate, improving the reliability of the connection. During disassembly, the two push blocks can be squeezed to make the two positioning rods move closer and away from the positioning groove, so that the insert rods lose their limit and can be pulled out, thereby disassembling the components.

[0029] Please see Figure 1-7 This utility model provides a technical solution: a split-type carbon-carbon composite crucible for vacuum sintering, including a base plate 1, and further comprising: first side plates 101 symmetrically arranged on the top two sides of the base plate 1, and second side plates 102 symmetrically arranged on the other two sides of the top of the base plate 1; a first step 103 is provided at the bottom of the first side plate 101, and positioning holes 104 are symmetrically opened through both sides of the first side plate 101; a second step 105 is provided below each of the two second side plates 102, and the width of the first step 103 and the second step 105 is 3mm; limiting holes 106 are symmetrically opened through both sides of the second side plates 102, and positioning bolts 107 are provided inside both the positioning holes 104 and the limiting holes 106; wherein, the two first side plates 102... A connecting post 109 is provided at the angle between the first side plate 101 and the two second side plates 102, and a connecting groove 108 is provided at each of the four corners of the bottom plate 1. The connecting post 109 is adapted to the connecting groove 108. The connecting post 109 is provided with a first threaded hole 110 and a second threaded hole 111 on the two sides near the first side plate 101 and the second side plate 102, respectively. The positioning bolt 107 is threaded to the first threaded hole 110 and the second threaded hole 111. This allows the crucible body to be easily separated from the material after sintering, so that the material can be completely removed. This avoids damage to the material and crucible caused by forcibly removing the material, improves product quality and production efficiency, and when the crucible is partially damaged, only the damaged part needs to be replaced instead of replacing the entire crucible, which greatly reduces maintenance costs.

[0030] A support plate 112 is fixedly installed at the bottom of the connecting column 109, and a connecting block 113 is fixedly installed at the bottom of the support plate 112. A placement groove 114 is provided at the top of the connecting column 109, and the connecting block 113 is adapted to the placement groove 114 for easy stacking. Support grooves 115 are provided through the bottom of both first side plates 101 and both second side plates 102, and positioning components 2 are provided inside the support grooves 115, allowing for further positioning between the first side plates 101 and the second side plates 102. The positioning assembly 2 includes two sets of positioning blocks 201 fixedly installed on the outer side of the base plate 1. The top of each positioning block 201 has symmetrically symmetrically perforated connecting holes 202. Support frames 203 are fixedly installed above the positioning blocks 201 on both the first side plates 101 and the two second side plates 102. Insert rods 204 are symmetrically perforated inside the support frames 203, and connecting frames 205 are fixedly installed on the tops of the two insert rods 204. The insert rods 204 are adapted to connect with the connecting holes 202, thus lifting the first side plate 1. 01. The reliability of the connection between the second side plate 102 and the side plate 1 is ensured. The bottom of the positioning block 201 is symmetrically equipped with a fixing block 206 between the two insertion rods 204. The fixing block 206 is internally connected to a positioning rod 207. A positioning groove 210 is provided on the lower side of one side of the insertion rod 204. The positioning rod 207 is engaged with the positioning groove 210 to position the insertion rod 204. A telescopic spring 208 is sleeved on the outer side of each of the two positioning rods 207. One end of the telescopic spring 208 is fixedly connected to the fixing block 206. The other end of the telescopic spring 208 is fixedly installed with a push block 209. The push block 209 is fixedly connected to the positioning rod 207, so that the positioning rod 207 can automatically reset after moving. All components are made of carbon-carbon composite material. The application of carbon-carbon composite material significantly reduces the weight of the crucible, improves the impact resistance and mechanical strength of the crucible, enables it to adapt to more complex vacuum sintering process requirements, extends the service life of the crucible, and reduces the time and cost waste caused by frequent crucible replacement.

[0031] Working principle: Before using this type of split-type carbon-carbon composite crucible for vacuum sintering, it is necessary to check the overall condition of the equipment to ensure it can operate normally. Figure 1 - Figure 7As shown, the crucible can be assembled from two first side plates 101, two second side plates 102, and a base plate 1. The crucibles can be stacked for use. When assembling the first side plates 101 and second side plates 102 with the base plate 1, the base plate 1 is placed on the first step 103 and the second step 105. The connecting post 109 is placed on the connecting groove 108 at the corner of the base plate 1. Then, positioning bolts 107 can be passed through the positioning holes 104 and the limiting holes 106 respectively, so that several positioning bolts 107 pass through the positioning holes 104 and the limiting holes 106 respectively, so that several... Each positioning bolt 107 is screwed into the first threaded hole 110 and the second threaded hole 111 respectively, thereby completing the overall assembly. After sintering, the material can be easily removed by disassembling the first side plate 101 and the second side plate 102. This allows the crucible body to be easily separated from the material after sintering, thus removing the material completely and avoiding damage to the material and crucible caused by forced material removal. This improves product quality and production efficiency. Furthermore, when the crucible is partially damaged, only the damaged part needs to be replaced, rather than the entire crucible, which greatly reduces maintenance costs.

[0032] After the first side plate 101 and the second side plate 102 are assembled, the positioning block 201 on the base plate 1 can extend out of the support groove 115. Then, two insert rods 204 can be inserted into the support frame 203. After that, the insert rods 204 are inserted into the connecting holes 202. Since the bottom end of the insert rod 204 is hemispherical, the bottom end of the insert rod 204 can push the positioning rod 207 to move through the curved surface, so that the positioning rod 207 moves to stretch the telescopic spring 208. Then, the insert rod 204 is inserted into the connecting frame 205 and abuts against the support frame 203. At this time, the positioning rod 207 can be aligned with the positioning groove 210. Under the action of the telescopic spring 208, the positioning rod 207 is engaged with the positioning groove 210, thereby further positioning the first side plate 101 and the second side plate 102 with the base plate 1, improving the reliability of the connection. During the disassembly process, the two push blocks 209 can be squeezed to make the two positioning rods 207 move closer and away from the positioning groove 210, so that the insertion rod 204 loses its limit and can be pulled out, thereby disassembling the component.

[0033] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
