[0002] Grinding wheels, also known as bonded abrasives, are made by bonding ordinary abrasives into a specific shape and strength. They are generally composed of abrasives, a bond, and pores, often referred to as the three elements of a bonded abrasive. Commonly classified by bond, they include ceramic grinding wheels, resin-bonded grinding wheels, and rubber-bonded grinding wheels.

[0003] Ceramic grinding wheel has the advantages of high strength, good heat resistance, sharp cutting, high grinding efficiency, not easy to heat up and clog during grinding, small thermal expansion, easy to control processing accuracy, etc. Compared with other grinding wheels, it solves the problems of low life of resin diamond, low grinding efficiency, and easy deformation of the grinding tool itself during the grinding process. When producing ceramic grinding wheels, it is necessary to mix metal powder, resin powder, ceramic and other raw materials in a certain proportion, and then pour the mixed raw materials into the pressing mold in a certain quantity, and then use scrapers and other items to scrape the raw material powder flat. However, some raw material powder will fall off during the scraping, and the fallen raw material powder will accumulate on the top of the workbench, affecting subsequent processing. In view of this, we proposed a ceramic grinding wheel production pressing mold. Utility Model Content

[0004] The purpose of the utility model is to solve at least one of the technical problems existing in the prior art and to provide a ceramic grinding wheel production pressing mold, which solves the problem that raw material powder falls on the top of the workbench during scraping and is inconvenient to clean.

[0008] Preferably, a baffle is fixedly connected to the lower surface of the circular plate, an anti-blocking rod is fixedly connected to the baffle, and a control rod is fixedly connected to the lower surface of the circular plate.

[0009] Preferably, a partition is fixedly connected to the inner wall of the discharge cylinder, and the partition is arranged in an inclined shape.

[0010] Preferably, the outer surface of the discharge barrel is provided with a discharge port communicating with the interior thereof, and the lower end of the control rod slides through the lower surface of the discharge partition.

[0011] Preferably, the bottom wall of the placement groove is fixedly connected to a motor, the output end of the motor is fixedly connected to a threaded rod, and the upper end of the threaded rod rotates and penetrates into the interior of the mold assembly.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] (1) The ceramic grinding wheel produces a pressing mold. After the raw materials are mixed and poured into the interior of the mold assembly, the raw materials are scraped flat by the scraping assembly. At this time, the raw materials that fall out will be collected by the conical groove and enter the interior of the storage box. With the help of the setting of the conical bottom wall of the storage box, the raw materials are further accumulated around the cylinder, which is convenient for the subsequent removal of the raw materials through the discharge cylinder. At the same time, the connecting plate provides partial support for the mold assembly. Through the above structure, after the raw materials are placed and scraped flat, the raw materials can be automatically collected by the cooperation of the storage box and the conical groove, avoiding the raw materials from being scattered on the top of the workbench and affecting the subsequent processing, and also avoiding the waste of raw materials.

[0015] (2) When the ceramic grinding wheel is used to produce a pressing mold, if there is a blockage, it is only necessary to push the control rod up and down repeatedly to make the anti-blocking rod move up and down. At the same time, when demoulding is required after the pressing is completed, the motor can be used to drive the threaded rod to rotate. Since the limit rod limits the movement trajectory of the inner mold column, the threaded rod will simultaneously drive the inner mold column to move in the vertical direction when it rotates, and the inner mold column will drive the demoulding base plate to move to complete the demoulding. Through the above structure, not only can the staff discharge the raw materials in the storage box more easily, but the anti-blocking rod can also be used to avoid the problem of blockage, and the grinding wheel after the pressing can be demoulded more conveniently with the help of the demoulding base plate.

The rotatable rotating table 10 is used to cooperate with the scraper 12 to scrape the raw materials flat. When the raw materials inside the storage box 2 are taken out, the operating rod 16 can be pushed upward. The operating rod 16 simultaneously drives the circular plate 13 to rise and compresses the spring 23. When the circular plate 13 rises, the baffle 14 is also driven to rise synchronously. After the baffle 14 rises, a closed second through groove 8 is opened, so that the raw materials can pass through the second through groove 8 into the interior of the discharge barrel 9.

At the same time, the connecting plate 4 is used to provide partial support for the mold assembly 5. By rotating the scraper 12 to be flush with the upper surface of the mold assembly 5, the rotatable rotating table 10 is used to cooperate with the scraper 12 to scrape the raw materials flat. When the raw materials inside the storage box 2 are taken out, the control rod 16 can be pushed upward, and the control rod 16 simultaneously drives the circular plate 13 to rise and compresses the spring 23, and When the circular plate 13 rises, the baffle 14 will also be driven to rise synchronously. After the baffle 14 rises, a closed second through groove 8 will be opened, so that the raw material can enter the interior of the discharge barrel 9 through the second through groove 8. At the same time, when the baffle 14 rises, the anti-blocking rod 15 will be driven to move. When a blockage occurs, it is only necessary to push the control rod 16 up and down repeatedly to make the anti-blocking rod 15 move up and down. At the same time, when demolding is required after the pressing is completed, the motor 24 can be used to drive the threaded rod 19 to rotate. Since the limit rod 22 limits the movement trajectory of the inner mold column 20, when the threaded rod 19 rotates, it will synchronously drive the inner mold column 20 to move in the vertical direction, and with the help of the inner mold column 20, the demolding bottom plate 21 is driven to move to complete the demolding.
