Description

Technical Field

[0001] This utility model relates to the field of graphite mold production technology, specifically to a support device for graphite molds. Background Technology

[0002] In the process of graphite mold production, a multi-station drilling machine and a support device are needed to drill holes in multiple workpieces for producing graphite molds. Before drilling, the multiple workpieces for producing graphite molds need to be clamped.

[0003] A search revealed a patent document CN202123277280.5 which discloses "a clamping mechanism for a multi-station drilling machine for producing graphite molds". This mechanism facilitates the simultaneous clamping of multiple workpieces. It uses a single motor to drive the clamping of multiple workpieces, resulting in low power consumption and high stability. The mechanism includes a support plate with an operating table connected to it via multiple support rods. The operating table has multiple clamping grooves, with a first clamping block and a second clamping block on each side of the clamping grooves.

[0004] Although this patent uses only a single motor to drive and simultaneously clamp multiple graphite molds, its transmission structure is extremely complex, with multiple gears and belts. This directly affects the transmission accuracy and makes it impossible to clamp the molds tightly, thus affecting the mold processing effect. Therefore, we propose a support device for graphite molds to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to provide a support device for graphite molds to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a support device for graphite molds, comprising a connecting plate, wherein a mold support assembly is fixedly connected to the top edge of the connecting plate by a plurality of struts, and a stepper motor is also fixedly installed on the top of the connecting plate, wherein a drive gear is fixedly connected to the output shaft end of the stepper motor.

[0007] The mold support assembly includes a support platform, which is fixedly connected to the top of several struts. A cylindrical block is fixedly connected to the center of the top of the support platform. At least four fan-shaped fixed platforms are equidistantly mounted around the outer side of the cylindrical block. A first clamping seat is mounted on one side of the fixed platform. A rotating plate is rotatably connected to the top of the support platform and at the position between two adjacent fixed platforms. A second clamping seat is mounted on the side of the rotating plate corresponding to the first clamping seat. A circular hole is opened at the center of the bottom of the support platform. A drive column is rotatably connected inside the circular hole. The bottom end of the drive column extends through the outside of the circular hole. Several gear teeth for cooperating with drive gears are equidistantly mounted around the surface of the drive column. A through arc-shaped groove is opened on the support platform at the position corresponding to the rotating plate. A crossbar is fixedly connected to the surface of the drive column at the position corresponding to the arc-shaped groove. The top of the crossbar is fixedly connected to the bottom of the rotating plate through a connecting rod.

[0008] Furthermore, an annular limiting rotating plate is fixedly connected to the surface of the drive column, and an annular groove adapted to the annular limiting rotating plate is opened on the wall of the hole corresponding to the circular hole of the support platform.

[0009] Furthermore, a turntable is installed at the bottom of the connecting plate, and a positioning base plate is installed at the bottom of the turntable.

[0010] Furthermore, a number of ear plates with screw holes are equidistantly mounted around the outer side of the positioning base plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: This invention places multiple graphite molds to be processed on the top of a support platform and fits them tightly against the groove of the first clamping seat. An annular limiting plate and an annular groove are used to axially limit the drive column. When clamping the molds, a stepper motor is activated, causing its output shaft to drive the drive gear to rotate. The meshing gear teeth drive the drive column to rotate. With the connection of the crossbeam and connecting rod, a rotating plate can rotate clockwise, thereby effectively clamping the molds using the second clamping seat on it. A turntable controls the rotation of the support platform, ensuring that graphite molds at different positions are aligned with the bottom of the processing machine. This support device for graphite molds has a reasonable structural design and is easy to use. A single motor drive enables synchronous clamping and positioning of multiple graphite molds. The transmission structure is simple, with high transmission accuracy and low loss, effectively ensuring the clamping effect of the molds, improving the processing effect of graphite molds, and enhancing product quality.

A second clamping seat 36 is installed on the side of the rotating plate 35 corresponding to the first clamping seat 34. Anti-slip plates are installed on the clamping surfaces of the first clamping seat 34 and the second clamping seat 36 to prevent slippage when clamping the graphite mold and affecting the processing effect.

[0017] A circular hole 37 is provided at the center of the bottom of the support platform 31. A drive column 38 is rotatably connected inside the circular hole 37. The bottom end of the drive column 38 extends through the outside of the circular hole 37.

[0021] In use, multiple graphite molds to be processed are placed on the top of the support platform 31 and pressed against the groove of the first clamping seat 34. The axial limit of the drive column 38 is achieved by using the annular limiting rotating plate 313 and the annular groove 314.
