Description

Technical Field

[0001] This utility model relates to the field of ceramic preparation molds, specifically a ceramic preparation mold polishing device. Background Technology

[0002] Ceramic preparation molds are specialized tools used to shape ceramic blanks. They are typically made of plaster, resin, metal, or porous materials, and their core function is to impart a predetermined shape and size to the ceramic material through a specific cavity structure. Mold design must consider shrinkage rate, draft angle, and surface finish to accommodate the shrinkage and deformation of the ceramic after sintering.

[0003] For example, according to patent announcement number CN214687093U, a ceramic mold includes a left mold, a right mold, an insert, a fixing pin, and an auxiliary locking mechanism. The right mold has an insert extending vertically on its sidewall where it contacts the left mold, and the left mold has a slot for inserting the insert on its sidewall where it contacts the right mold. A first insertion hole is provided on the outer sidewall extending along the length of the slot, and a corresponding fixing groove is provided on the inner sidewall. The insert has a second insertion hole facing the first insertion hole. The fixing pin passes through the first and second insertion holes and is inserted into the fixing groove for fixation. An auxiliary locking mechanism is provided at the bottom of the left and right molds. This ceramic mold, as described in this invention, achieves fixation of the ceramic mold and solves the problem of flash on the blank.

[0004] In the ceramic mold making process, operators need to hold the mold and polish it using a polishing disc. However, the existing polishing disc and rotating shaft are rigidly connected, making it difficult for operators to control the contact force between the mold and the polishing disc during polishing, thus affecting the stability of the polishing quality of the ceramic mold. Therefore, there is an urgent need in the market to develop a ceramic mold polishing equipment to help solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide a ceramic preparation mold polishing device to solve the problem mentioned in the background art, which is that the existing polishing disc and rotating shaft are rigidly connected, making it difficult for personnel to control the contact force between the mold and the polishing disc during polishing, thus affecting the stability of the polishing quality of the ceramic mold.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a ceramic preparation mold polishing device, comprising a frame 1, a limiting tube 101 fixedly connected to the middle of the upper end of the frame 1, a rotating shaft 2 rotatably connected inside the limiting tube 101, a fixed cylinder 102 fixedly connected to the front end of the frame 1 and the front end of the limiting tube 101, the front end of the rotating shaft 2 extending into the fixed cylinder 102 and fixedly connected to a force transmission cylinder 3, the front and rear ends of the middle section between the outer wall of the force transmission cylinder 3 and the interior of the fixed cylinder 102 being connected by bearings 103 to maintain stable rotation of the force transmission cylinder 3 inside the fixed cylinder 102, a driving device 201 fixedly connected to the rear end of the frame 1 and the rear end of the limiting tube 101, a driving motor 202 fixedly installed inside the driving device 201, the rear end of the rotating shaft 2 extending into the driving device 201 and connected to the output shaft of the driving motor 202 via a coupling, the driving motor 202 drives the rotating shaft 2 to rotate, thereby causing the rotating shaft 2 to drive the force transmission cylinder 3 to rotate.

[0024] Please see Figure 2 and Figure 4 The force transmission cylinder 3 has a telescopic groove 301 in the middle. A guide rod 303 is fixedly connected to the middle of the rear end face of the telescopic groove 301. A telescopic shaft 5 is provided inside the telescopic groove 301 and at the front end of the guide rod 303. A circular slot 502 is provided in the middle of the rear end face of the telescopic shaft 5. The front end of the guide rod 303 extends into the circular slot 502. Four trapezoidal sliding grooves 302 are arranged in a ring array on the inner wall of the telescopic groove 301. Four trapezoidal connecting keys 501 are fixedly connected in a ring array on the outer wall of the telescopic shaft 5 and at the rear end of the limiting ring 4. The four trapezoidal connecting keys 501 slide into the four trapezoidal sliding grooves 302 respectively. Through the cooperation of the trapezoidal connecting keys 501 and the trapezoidal sliding grooves 302, the telescopic shaft 5 can be driven to rotate synchronously when the force transmission cylinder 3 rotates. A push ring 304 is connected to the front end of the middle of the guide rod 303. A telescopic shaft 5 is provided on the guide rod 303 between the push ring 304 and the rear end face of the telescopic groove 301. A force transmission spring 305 is provided. The front end of the force transmission cylinder 3 extends out of the front end of the fixed cylinder 102 and is connected to a limit ring 4. The limit ring 4 is fixedly connected to the front end face of the force transmission cylinder 3 by multiple first screws 401. The limit ring 4 limits the front end of the trapezoidal connecting key 501, thereby preventing the rear end of the telescopic shaft 5 from disengaging from the telescopic groove 301. The front end of the telescopic shaft 5 extends out of the front end face of the force transmission cylinder 3 and passes through the middle of the limit ring 4, and is connected to a polishing disc 6. The polishing disc 6 is fixedly connected to the front end of the telescopic shaft 5 by a left-hand screw 601. When a person holds the ceramic mold against the polishing disc 6, the polishing disc 6 can push the telescopic shaft 5 to move backward, thereby causing the rear end of the telescopic shaft 5 to push the push ring 304 to move backward on the guide rod 303 and compress the force transmission spring 305. At the same time, the restoring force of the force transmission spring 305 pushes the push ring 304 and the telescopic shaft 5 to extend forward, so that the telescopic shaft 5 drives the polishing disc 6 to extend forward and contact the ceramic mold for polishing.

[0025] Working Principle: During operation, the drive motor 202 rotates the rotating shaft 2, which in turn transmits power to the telescopic shaft 5 via the force transmission cylinder 3. When the operator holds the ceramic mold and lightly presses the polishing disc 6, the polishing disc 6 experiences a reverse force, pushing the telescopic shaft 5 backward along the trapezoidal groove 302. At this time, the trapezoidal connecting key 501 slides along the trapezoidal groove 302 while maintaining transmission. The telescopic shaft 5 compresses the force transmission spring 305 via the push ring 304. Under the elastic action of the force transmission spring 305, the push ring 304 consistently applies a forward thrust to the telescopic shaft 5, maintaining a constant flexible contact pressure between the polishing disc 6 and the mold surface. This elastic buffer structure ensures the stability of the polishing force while avoiding overpressure damage caused by rigid contact. When the polishing angle changes, the telescopic shaft 5 can adaptively adjust its extension length to achieve uniform polishing in conjunction with the rotating polishing disc 6. Finally, different specifications of polishing discs 6 can be quickly replaced using the left-hand screw 601 to meet the surface treatment needs of various molds.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
