[0002] Diamond saw blade is a kind of high-performance cutting tool with diamond as cutting edge. Its core structure is to embed diamond particles in the edge of metal matrix (such as steel or alloy) by sintering, electroplating or brazing process, diamond as the hardest substance in nature, make saw blade have excellent wear resistance and cutting efficiency, especially in the field of hard material processing, the saw blade is widely used in stone mining, building concrete cutting, ceramic processing and geological exploration industry, can efficiently cut granite, marble, reinforced concrete and other high-strength materials, it has the advantages of fast cutting speed, long service life, high flatness of section, low noise; And its design realizes the good balance of cutting performance and cost by optimizing diamond distribution density and matrix material, becomes the key tool in industrial cutting field; However, in the process of saw blade die casting, the alignment of upper and lower molds is a problem, once the alignment deviation occurs, it will lead to the unsatisfactory die casting effect, affect the overall quality and performance of saw blade, therefore, solving the alignment problem of upper and lower molds is crucial for improving the die casting quality and production efficiency of diamond saw blade, for the above problems, there may be technical means to solve in prior art, but the present case wants to provide an alternative or replacement technical scheme. SUMMARY

[0003] To achieve the above purpose, the utility model realizes through the following technical scheme: a kind of diamond saw blade die casting die, comprising: upper mold block, lower mold block and coupling insertion column, the coupling insertion column is installed on the upper mold block, the spare injection structure is installed on the lower mold block, the closing anti-deviation pressure casting structure is installed on the upper mold block, the closing anti-deviation pressure casting structure, including: side positioning column, several upper saw teeth forming blocks, several lower saw teeth forming blocks, injection recess, several injection through holes, a pair of mechanism link blocks, coupling insertion slot and side positioning slot;

[0004] The side positioning post is installed on the upper mold block and is connected to the coupling insertion post. The lower mold block has the coupling insertion groove and the side positioning groove. The side positioning post is inserted into the side positioning groove and the coupling insertion post is inserted into the coupling insertion groove. A plurality of upper serrated forming blocks are respectively installed on the upper mold block and mesh with a plurality of lower serrated forming blocks. A plurality of lower serrated forming blocks are respectively installed on the lower mold block. The lower mold block has the injection groove and the plurality of lower serrated forming blocks are respectively installed in the injection groove. The upper mold block has a plurality of injection through holes and the lower mold block has a plurality of injection through holes. A pair of mechanism connecting blocks are respectively installed on the upper mold block.

[0005] It should be noted that, as described above, the upper mold block and the die-casting mechanism can be connected by a pair of connecting blocks. First, the coupling insertion post and the side positioning post are aligned and inserted with the coupling insertion slot and the side positioning slot on the lower mold block, respectively, until the upper mold block and the lower mold block fit together (the most important aspect of a saw blade is the angle of the saw teeth; if the alignment is inaccurate, the angle of the saw teeth on the die-cast blank will not meet the standard, thus greatly reducing the performance of the finished saw blade after subsequent processing). Then, diamond mixture powder is injected through the injection holes on the upper mold block. The lotus leaf anti-stick coating inside the injection holes can effectively prevent the powder from sticking to the injection hole. Once the material powder is filled into the material through hole, the die-casting mechanism is driven to apply downward pressure, gradually compacting the material powder in the injection groove. Then, the upper mold block and the lower mold block are separated, and the die-cast blank is taken out for the next sintering operation, finally completing the finished product. Multiple upper and lower sawtooth forming blocks are intertwined. After the material powder is die-cast, the formed sawtooth will make the subsequent cutting effect of the finished product very perfect. The anti-oxidation and scratch-resistant coating layer set on the upper mold block can effectively prevent the upper mold block from oxidizing and slag after long-term use, thus preventing contamination of the mixed material powder. The installation slot set on the mechanism connecting block can make the connection between the mechanism connecting block and the die-casting mechanism tighter and stronger.

[0006] Preferably, the spare filling structure includes: several through-hole sealing posts, several adhesive anti-sticking sheets, several external sealing blocks, and several connecting locking bolts;

[0007] A plurality of the aforementioned anti-sticking sheets are respectively installed on a plurality of the aforementioned through-hole sealing posts, a plurality of the aforementioned through-hole sealing posts are respectively inserted into a plurality of the aforementioned injection through holes, and a plurality of the aforementioned through-hole sealing posts are respectively installed on a plurality of the aforementioned external sealing blocks, a plurality of the aforementioned connecting locking bolts are respectively inserted into the aforementioned lower mold block, and a plurality of the aforementioned connecting locking bolts are respectively inserted into a plurality of the aforementioned external sealing blocks;

[0008] It should be noted that, as described above, after the blank in the injection groove is die-cast, it is still necessary to add new mixture (for example, to make a coating layer, increase the toughness of the finished blank, or the finished product layer, etc.). First, lift the upper mold block appropriately, inject new mixture into the side of the upper mold block through the injection through hole on the upper mold block, then loosen the connecting locking bolt, remove the external sealing block and the through hole sealing post and the anti-sticking plate on them, inject new mixture into them, and then reinsert the through hole sealing post into the injection through hole on the lower mold block, and reinsert the external sealing block and the lower mold block to seal it, and then apply pressure again to die-cast a composite layer diamond saw blade blank.

[0009] Preferably, the connecting locking bolt body is provided with a hexagonal thread;

[0010] Preferably, the connecting block of the mechanism is provided with an installation slot;

[0011] Preferably, the injection through hole is provided with a lotus leaf anti-stick coating;

[0012] Preferably, the upper mold block is provided with an anti-oxidation and scratch-resistant coating layer. Beneficial effects

The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further. Example

[0021] The present invention will now be described in detail with reference to the accompanying drawings, such as... Figures 1-4As shown, a diamond saw blade die-casting mold includes: an upper mold block 1, a lower mold block 2, and a coupling insertion post 3. The coupling insertion post 3 is installed on the upper mold block 1. A spare injection structure is installed on the lower mold block 2. An anti-deviation die-casting structure is installed on the upper mold block 1. The anti-deviation die-casting structure includes: a side positioning post 4, several upper saw tooth forming blocks 5, several lower saw tooth forming blocks 6, an injection groove 7, several injection through holes 8, a pair of mechanism connecting blocks 9, a coupling insertion groove 10, and a side positioning groove 11. The side positioning post 4 is installed on the upper mold block 1 and is connected to the coupling insertion post 3. The lower mold block 2 has a coupling insertion groove 10 and a side positioning groove 11. The side positioning post 4 is inserted into the side positioning groove 11, and the coupling insertion post 3 is inserted into the coupling insertion groove 10. Several upper sawtooth forming blocks 5 are respectively installed on the upper mold block 1, and several upper sawtooth forming blocks 5 are respectively connected to several lower sawtooth forming blocks 1. The toothed forming blocks 6 mesh with each other, and several lower toothed forming blocks 6 are respectively installed on the lower mold block 2. The lower mold block 2 has an injection groove 7, and several lower toothed forming blocks 6 are respectively installed in the injection groove 7. The upper mold block 1 has several injection through holes 8, and the lower mold block 2 has several injection through holes 8. A pair of mechanism connecting blocks 9 are respectively installed on the upper mold block 1. The spare injection structure includes: several through hole sealing posts 12, and several anti-sticking and bonding components. The assembly includes a sheet 13, several external sealing blocks 14, and several connecting locking bolts 15; several of the bonding anti-sticking sheets 13 are respectively installed on several of the through-hole sealing posts 12, several of the through-hole sealing posts 12 are respectively inserted into several of the injection through holes 8, and several of the through-hole sealing posts 12 are respectively installed on several of the external sealing blocks 14, several of the connecting locking bolts 15 are respectively inserted into the lower mold block 2, and several of the connecting locking bolts 15 are respectively inserted into several of the external sealing blocks 14.

[0022] According to the appendix Figures 1-4It is concluded that the upper mold block 1 and the die-casting mechanism can be connected by a pair of connecting blocks 9. First, the coupling insertion post 3 and the side positioning post 4 are aligned with the coupling insertion groove 10 and the side positioning groove 11 on the lower mold block 2 and inserted until the upper mold block 1 and the lower mold block 2 fit together (the most important part of the saw blade is the angle of the saw teeth. If the alignment is not accurate, the angle of the saw teeth on the saw tooth blank formed after die casting will not meet the standard, which will greatly reduce the performance of the finished saw blade after subsequent processing). Then, from the upper mold... Diamond powder mixture is injected into the injection holes 8 on block 1. The lotus leaf anti-stick coating inside the injection holes 8 effectively prevents the powder from adhering to them. Once the injection holes are full, the die-casting mechanism applies downward pressure, gradually compacting the powder in the injection grooves 7. Then, the upper mold block 1 and lower mold block 2 are separated, and the die-cast blank is removed for the next sintering operation, ultimately completing the finished product. Multiple upper serrated forming blocks 5 and lower serrated forming blocks 6 are interleaved; after die casting, the powder forms... The serrated edges ensure a perfect cutting effect for the final product. The anti-oxidation and scratch-resistant coating on the upper mold block 1 effectively prevents oxidation and slag buildup after prolonged use, thus preventing contamination of the mixed powder. The mounting slot on the mechanism connecting block 9 allows for a tighter and more robust connection between the mechanism connecting block 9 and the die-casting mechanism. After the blank in the injection groove 7 is die-cast, it is still necessary to add new mixed powder (e.g., to create a coating layer, increase the toughness of the finished blank, or improve the finished product's texture). A moderate amount of powder should be added initially. Lift the upper mold block 1, inject new mixture into the side of the upper mold block 1 through the injection hole 8 on the upper mold block 1, then loosen the connecting locking bolt 15, remove the external sealing block 14 and the through hole sealing column 12 and the bonding anti-sticking plate 13 on them, inject new mixture into them, and then reinsert the through hole sealing column 12 into the injection hole 8 on the lower mold block 2, and reinsert the external sealing block 14 to the lower mold block 2 to seal it, and then apply pressure again to die-cast a composite layer diamond saw blade blank.
