Description

Technical Field

[0001] This utility model belongs to the field of casting process technology, and in particular relates to a slurry tank for casting process. Background Technology

[0002] Casting is a technique for preparing polymer thin films that involves mixing, evaporation, drying, and cutting to obtain the desired finished product. Therefore, casting has become an essential technology for the production of electronic components and a pillar technology for the production of multilayer ceramic substrates and devices, offering broad prospects for the miniaturization of ultra-large-scale integrated circuits and electronic devices. The specific process of casting involves mixing ceramic powder with various additives (binders, plasticizers, dispersants, etc.) in a solvent to form a uniform and stable material. During casting, the material flows from the trough onto the substrate, forming a wet tape through the relative movement of the scraper and the substrate. The thickness is controlled by the distance between the scraper and the substrate. The wet film, along with the substrate, is fed into a drying chamber. During solvent evaporation, the film, possessing a certain strength and flexibility, bonds the ceramic particles together through the film-forming action of the binder. The dried film, along with the substrate or detached from the substrate, is ready for use. It can then be punched, stamped, or cut to the desired shape, and finally sintered to obtain the finished product.

[0003] Currently, slurry tanks are generally fixed in depth and width to match specific production processes, and the only adjustable parameter is usually the flow rate. Therefore, when producing different batches or products, defects of varying quality can easily occur. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A slurry tank for a casting process includes a slurry tank body and a cover disposed on the slurry tank body, and also includes an adjustment part disposed inside the slurry tank body;

[0006] The slurry tank body includes a cavity and a guide slope. The angle between the guide slope and the horizontal direction is denoted as C, and the angle C is 110° to 135°. The cavity depth is denoted as H1, and the cavity width is denoted as W. The depth H1 is 100 to 200 mm, and the width W is 200 to 500 mm.

[0007] The adjustment unit includes an adjustment plate and at least two sets of adjustment columns fixedly connected to the adjustment plate. Each adjustment column is fitted with an elastic element, one end of which abuts against the adjustment plate and the other end of which abuts against the inner wall of the cavity. A cylinder is also provided inside the cavity, which is rotatably connected to the slurry tank body. The cylinder is used to stir the slurry inside the cavity.

[0008] Furthermore, a fastener is provided on the side of the adjusting column away from the elastic element, and the position of the adjusting plate can be adjusted when the fastener is adjusted.

[0009] Furthermore, the height from the bottom of the cavity to the guide slope is denoted as H2, where H2 = H1 - (5~10mm). The intersection of the top surface of height H2 and the guide slope is marked with a rounded angle, denoted as R, where R is 10~30mm.

[0010] Furthermore, the cylinder can also be connected to a driving element, which can drive the cylinder to rotate.

[0011] Furthermore, the regulating plate is connected to the slurry equipment via a pipe, and the slurry enters the cavity through the pipe.

[0012] Furthermore, the driving element is a motor.

[0013] Furthermore, the elastic element is a spring.

[0014] The beneficial effects of this utility model are:

[0015] This invention features an adjustable adjustment plate inside the slurry tank. Adjusting the position of the plate allows for changes in the size of the slurry tank cavity, enabling rapid adjustment of the slurry's storage time within the cavity, controlling the slurry's temperature, and the time it takes for the slurry to flow onto the product. Simultaneously, a rotating cylinder is located within the cavity. As the cylinder continuously rotates, the slurry is agitated along the cylinder and flows out from the guide slope, eventually flowing onto the product. Other slurry tanks allow the slurry to remain in the tank for a certain period before flowing out, causing newly flowing slurry to settle at the bottom while only the top slurry flows out. This results in sedimentation over prolonged production. This invention, however, prevents slurry sedimentation in the slurry tank by using a continuously rotating cylinder, thus avoiding impacts on slurry quality and consequently, product quality.
