[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] Example: Reference Figure 1-4 The circular ceramic heater forming device shown comprises a base 1, a bottom mold 2 is fixed to the upper end of the base 1, a door frame 11 is fixed to one side of the base 1, and a driving assembly 4 is installed at the front end of the door frame 11;

[0027] The upper die set 3 is installed at the lower end of the driving component 4, and the driving component 4 drives the upper die set 3 to rise and fall and rotate. The upper die set 3 includes a semi-molding upper die 31, a clamp 32 and a pressing die 33. The semi-molding upper die 31, the clamp 32 and the pressing die 33 are all adapted to the bottom die 2;

[0028] It also includes a positioning mechanism and a controller, the positioning mechanism is used to determine whether the positions of the semi-molded upper mold 31, the clamp 32, and the die 33 correspond to the bottom mold 2;

[0029] The controller is used to receive and process the electrical signal given by the positioning mechanism, and is also used to control the operation of the driving assembly and the clamp 32.

[0030] Based on the above structure, the upper mold group 3 can be driven to rise and fall and rotate through the driving component 4, so that the semi-molded upper mold 31, the clamp 32 and the pressing mold 33 can cooperate with the bottom mold 2 in sequence to complete the semi-finished product pressing, heating coil placement and finished product pressing and molding operations in sequence, thereby completing the molding operation of the annular ceramic heater at one time in a smaller space. Compared with the existing large-scale assembly line equipment, the molding device has the advantages of small footprint, short molding cycle and high finished product quality while taking into account production efficiency. It only needs to be equipped with the existing automatic loading and unloading mechanism to realize the fully automatic annular ceramic heater molding operation, which is also conducive to the promotion and improvement of the annular ceramic heater molding device.

[0031] Furthermore, a circular forming groove is provided on the bottom mold 2, and a pressure ring adapted to the forming groove is provided at the lower end of the semi-molding upper mold 31, and the height of the pressure ring is half of the height of the forming groove. The lower end of the pressure ring of the semi-molding upper mold 31 is integrally formed with an annular protrusion 311. When the semi-molding upper mold 31 and the bottom mold 2 are combined, the semi-finished substrate of the lower circular ceramic heater can be formed. At the same time, the annular protrusion 311 is used to reserve an annular groove for placing the heating coil, which is convenient for the subsequent placement of the heating coil.

[0032] Furthermore, the clamp 32 is used to clamp the heating coil, and the clamp 32 is a pneumatic clamp with a flexible contact portion provided on the inner side.

[0033] Furthermore, the lower end of the die 33 is also compatible with the molding groove of the bottom mold 2. A through hole 331 is provided on the die 33 which vertically penetrates the die 33. The through hole 331 is for the pin of the heating coil to pass through. When the die 33 and the bottom mold 2 are molded together, the molding operation of the upper annular ceramic heater can be completed, thereby completing the molding operation of the entire annular ceramic heater. At the same time, the setting of the through hole 331 can allow the pin of the heating coil to pass through, avoiding subsequent opening of holes to access the pins, and improving the molding quality.

[0034] Furthermore, the positioning mechanism includes a work station 6 and a sensor 7. There are multiple work stations 6 and they correspond to the semi-molded upper mold 31, the clamp 32 and the die 33 respectively. The multiple work stations 6 are respectively fixed to the upper surface of the base 1 or fixedly embedded in the middle of the bottom mold 2. The sensor 7 is located between the semi-molded upper mold 31 and the die 33 and is used to read the position and information of the work station 6. Through the setting of the work station 6 and the sensor 7, the positions of the semi-molded upper mold 31, the clamp 32 and the die 33 can be located, so as to facilitate the controller to control the operation of the drive component 4, so that the semi-molded upper mold 31, the clamp 32 and the die 33 can be accurately adapted to the bottom mold 2, thereby avoiding the occurrence of offset of the semi-molded upper mold 31, the clamp 32 and the die 33, improving the accuracy of the molding operation, avoiding burrs or cracks on the finished product, and thus improving product quality.

[0035] Further, the driving assembly 4 includes a hydraulic cylinder 41 and a motor 43. The hydraulic cylinder 41 is fixed on the gantry 11 and the piston rod extends downward. The lower end of the piston rod of the hydraulic cylinder 41 is fixed with a fixing frame 42.

[0036] The motor 43 is fixed on the fixed frame 42, and the output shaft of the motor 43 rotates and passes through the lower end of the fixed frame 42 and is fixed with a rotating bracket 44. The rotating bracket 44 is a cross-shaped bracket. The four ends of the rotating bracket 44 are respectively used to fix the semi-molded upper mold 31, the clamp 32, the die 33 and the sensor 7. The hydraulic cylinder 41 controls the lifting and lowering of the fixed frame 42, and the motor 43 controls the rotation of the rotating bracket 44, thereby realizing the lifting and rotation of the semi-molded upper mold 31, the clamp 32, the die 33 and the sensor 7, and completing the molding operation under the control of the controller.

[0037] Furthermore, a material storage tray 5 is fixed on the upper surface of the base 1, and the material storage tray 5 is used to place the heating coil or the formed annular ceramic heater. The material storage tray 5 is located on one side of the bottom mold 2 and is also provided with a work station 6, which can temporarily place the heating coil or the formed annular ceramic heater, thereby facilitating the forming operation of the annular ceramic heater and making the production operation faster and more efficient.

[0038] Working principle of the utility model: in daily use, the hydraulic cylinder 41 controls the lifting and lowering of the fixed frame 42, and the motor 43 controls the rotation of the rotating bracket 44, so as to realize the lifting and rotating of the semi-molded upper mold 31, the clamp 32, the die 33 and the sensor 7, so that the semi-molded upper mold 31, the clamp 32 and the die 33 can cooperate with the bottom mold 2 in sequence to complete the semi-finished product pressing, the heating coil placement and the finished product pressing and molding operations in sequence. Specifically, when the semi-molded upper mold 31 and the bottom mold 2 are molded together, the semi-finished product matrix of the lower annular ceramic heater can be formed, and at the same time, the annular protrusion 311 is used to reserve an annular groove for placing the heating coil, which is convenient for the subsequent placement of the heating coil. The clamp 32 is used to clamp the heating coil and place it on the semi-finished product matrix. When the die 33 and the bottom mold 2 are molded together, the molding operation of the upper annular ceramic heater can be completed, thereby completing the molding operation of the entire annular ceramic heater;

[0039] In the next process, the positions of the semi-molded upper mold 31, the clamp 32 and the die 33 can be located by setting the workstation position 6 and the sensor 7, so that the controller can control the operation of the driving assembly 4, so that the semi-molded upper mold 31, the clamp 32 and the die 33 can be accurately matched with the bottom mold 2, thereby avoiding the occurrence of the semi-molded upper mold 31, the clamp 32 and the die 33 offset, improving the accuracy of the molding operation, avoiding burrs or cracks on the finished product, and thus improving the product quality;

[0040] Thereby, the forming operation of the annular ceramic heater can be completed at one time in a smaller space. Compared with the existing large-scale assembly line equipment, the forming device has the advantages of small footprint, short forming cycle, and high finished product quality while taking into account production efficiency. It only needs to be combined with the existing automatic loading and unloading mechanism to realize the fully automatic forming operation of the annular ceramic heater, which is also conducive to the promotion and improvement of the annular ceramic heater forming device.
