A molding apparatus for preparing quartz crucibles

Abstract

This application discloses a molding apparatus for preparing quartz crucibles, including a mounting box, a lifting unit, a first translation unit, and a second translation unit. A mounting plate is fixedly connected to the second translation unit, and multiple molding plates are mounted on the mounting plate. This molding apparatus mounts four molding plates, allowing for the selection of molding plates of different specifications when producing quartz crucibles of varying sizes, thus improving the equipment's versatility. Two molding plates located on the same side of the mounting plate are mounted using a sliding plate and a connecting plate, ensuring that the two molding plates on the same side do not interfere with each other during movement. The lifting unit enables lifting and lowering movement, giving the molding apparatus greater adaptability and flexibility. The first translation unit moves the entire mounting plate within the crucible mold, while the second translation unit only needs to perform a small-amplitude movement to move the required molding plate to the center of the molding mold for material scraping and molding.

Description

Technical Field

[0001] This invention relates to the field of quartz crucible preparation technology, and more specifically, to a forming apparatus for preparing quartz crucibles. Background Technology

[0002] Currently, the common practice before firing crucibles is to tilt the central axis of the crucible mold outward at a certain angle in the vertical plane, and then use a motor to drive the crucible mold to rotate at a constant speed around its own axis. Quartz sand is poured into the crucible mold, allowing it to adhere to the inner wall of the mold. Then, the axis of the rotating crucible mold is straightened, and a forming plate is used to scrape the quartz sand layer to make its surface smooth. The shape and size of the forming plate must match the shape and size of the crucible to be formed.

[0003] However, when producing quartz crucibles, companies often need to prepare crucibles of different specifications (different shapes and sizes). Existing forming plates can often only match one specification of crucible, and their versatility is limited. Therefore, existing forming equipment has certain limitations. When producing quartz crucibles of different specifications, the inner wall shapes of the crucibles are different, and the scraper is difficult to adapt to the scraping requirements of crucibles of different specifications, thus failing to meet production needs. Summary of the Invention

[0004] The present invention aims to overcome the shortcomings of the prior art and provide a forming apparatus for preparing quartz crucibles.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a molding device for preparing quartz crucibles, comprising a mounting box, a lifting unit installed at the mounting box, a first translation unit installed at the lifting unit, and a second translation unit installed at the first translation unit, wherein a mounting plate is fixedly connected to the second translation unit, and a plurality of molding plates are installed at the mounting plate.

[0006] Furthermore, a lifting motor is installed at the mounting box. The mounting box has a vertical groove with an open side. The vertical groove contains a vertical slide rail and a lifting screw driven by the lifting motor. The lifting unit has a vertical slide groove that mates with the vertical slide rail and a threaded hole that mates with the lifting screw. The lifting unit has a first slide rail, a first translation motor, a first guide rod, and a first translation screw driven by the first translation motor. The first translation unit has a first slide groove that mates with the first slide rail, a first guide hole that mates with the first guide rod, and a threaded hole that mates with the first translation screw. The first translation unit also has a second slide groove, a second translation motor, a second guide rod, and a second translation screw that mates with the second guide rod. The second translation unit has a second slide rail that mates with the second slide groove, a second guide hole that mates with the second guide rod, and a threaded hole that mates with the second translation screw.

[0007] Thus, driven by the lifting motor, the first translation motor, and the second translation motor, the forming plate achieves lifting and horizontal movement.

[0008] Furthermore, the lifting unit is in the shape of an inverted U, and a first bearing that cooperates with the first translation screw is installed at the lifting unit; L-shaped plates are fixedly connected to both sides of the first translation unit, the second translation motor is installed at one of the L-shaped plates, and a second bearing that cooperates with the second translation screw is installed at the other L-shaped plate.

[0009] This ensures precise and smooth movement, and the bearings reduce friction, thus improving service life and operating efficiency.

[0010] Furthermore, the bottom end of the lifting screw is mounted on the bottom end of the vertical groove via a third bearing and a bearing seat.

[0011] Therefore, the friction of the lifting screw can be reduced by using the third bearing and bearing housing, thereby improving the lifting efficiency and lifespan.

[0012] Furthermore, the lifting motor is mounted on the top of the mounting box.

[0013] This facilitates maintenance and operation, and by being installed on top, the lifting motor can drive the lifting unit to move vertically via the lifting screw.

[0014] Furthermore, there are two of each of the first and second guide rods.

[0015] This enhances the stability and accuracy of the translation of the first and second translation units, avoiding adverse effects caused by offset and shaking.

[0016] Furthermore, the multiple forming plates are designated as a first forming plate, a second forming plate, a third forming plate, and a fourth forming plate. One side of the mounting plate has a first strip groove and a second strip groove, and the other side has a third strip groove and a fourth strip groove. A first motor housing is mounted on one side of the mounting plate, and a second motor housing is mounted on the other side. A first drive motor and a second drive motor are installed in the first motor housing, and a third drive motor and a fourth drive motor are installed in the second motor housing. The first drive motor drives a first drive screw located in the first strip groove, the second drive motor drives a second drive screw located in the second strip groove, the third drive motor drives a third drive screw located in the third strip groove, and the fourth drive motor drives a fourth drive screw located in the fourth strip groove. The first forming plate is connected to a first connecting plate. A first connecting plate is connected to a first sliding plate that can slide within a first slot; a second forming plate is connected to a second sliding plate that can slide within a second slot; the second forming plate is closer to the mounting plate than the first forming plate; a third forming plate is connected to a third sliding plate that can slide within a third slot; a fourth forming plate is connected to a second connecting plate; the second connecting plate is connected to a fourth sliding plate that can slide within a fourth slot; the third forming plate is closer to the mounting plate than the fourth forming plate; the first sliding plate has a threaded hole that mates with a first drive screw; the second sliding plate has a threaded hole that mates with a second drive screw; the third sliding plate has a threaded hole that mates with a third drive screw; and the fourth sliding plate has a threaded hole that mates with a fourth drive screw.

[0017] Thus, through the cooperation of the drive screw and the sliding plate, the forming plate can slide within the corresponding slot.

[0018] Furthermore, the first, second, third, and fourth forming plates are all L-shaped with curved chamfers, and the specifications of the first, second, third, and fourth plates are different from each other.

[0019] Therefore, when producing quartz crucibles of different specifications according to production needs, different specifications of forming plates can be selected to meet production needs and improve the versatility of the equipment.

[0020] Furthermore, each of the first, second, third, and fourth strip grooves has a slide rail unit; each of the first, second, third, and fourth sliding plates has a slide groove unit that cooperates with the slide rail unit.

[0021] This facilitates the sliding of the first, second, third, and fourth sliding plates.

[0022] Furthermore, both sides of the mounting plate have clamping units, and the first, second, third, and fourth sliding plates each have strip-shaped protrusions; the clamping unit includes two L-shaped mounting blocks, a clamping plate located between the two mounting blocks, and a limiting guide post installed on the mounting plate. A telescopic cylinder is installed on the mounting block, and the movable end of the telescopic cylinder is fixedly connected to the clamping plate. The clamping plate has an anti-slip pad and a limiting through hole that cooperates with the limiting guide post.

[0023] This allows the unused forming plate to be more stable during the scraping and forming process by pressing with a telescopic cylinder.

[0024] Furthermore, four limiting guide posts are installed on each side of the mounting plate.

[0025] This enhances the stability of the pressure plate movement.

[0026] Beneficial effects:

[0027] 1) The molding device of this application is equipped with 4 molding plates, so that when producing quartz crucibles of different specifications, different specifications of molding plates can be selected according to production needs, thereby meeting production needs, improving the versatility of the equipment, and achieving consistency in scraping molding.

[0028] 2) The molding device of this application has two molding plates located on the same side of the mounting plate, one of which is installed by a sliding plate and a connecting plate, so that the two molding plates on the same side do not interfere with each other when they move, which can improve the efficiency and reliability of the molding device.

[0029] 3) The molding device of this application has a lifting unit that enables lifting and moving, making the molding device more adaptable and flexible. The first translation unit enables the entire mounting plate to move inside the crucible mold, and the second translation unit only needs to achieve a small range of movement to move the molding plate to be used to the middle position of the molding mold for scraping and molding the material.

[0049] Working Principle: The molding device of this application is equipped with four molding plates.

Automated control of the molding process solves the problem of uneven material layer thickness, improves molding efficiency, reduces worker workload, minimizes direct contact between the worker and quartz sand during molding, and improves crucible firing quality.

[0050] Specifically, using auxiliary tools, quartz sand is sprinkled onto the inner surface of the crucible mold, ensuring it adheres as evenly as possible to the inner wall, thus completing the feeding process. Next, a suitable forming plate is selected based on actual needs, and the remaining forming plates are fixed using clamping plates, such as...

Then, the lifting unit, the first translation unit, and the second translation unit are activated to adjust the position of the forming plate to be used, moving it to the center of the forming mold for scraping and forming the material. Through automated control of the forming process, the problem of uneven material layer thickness is solved, improving the efficiency of the forming process, reducing the labor intensity of workers, and minimizing direct contact between the worker and the quartz sand during the forming process, thus improving the quality of crucible firing.
