Abstract
Description
Technical Field
[0001] The utility model belongs to the field of manufacturing refractory brick forming molds for quartz glass kilns, and specifically relates to a refractory brick forming mold with a rectangular groove. Background Art
[0002] Quartz glass kilns are one of the most widely used areas for refractory bricks. In quartz glass kilns, refractory bricks usually need to have certain grooves or channels to accommodate the flow of glass liquid. At present, the molding of refractory bricks with rectangular grooves is mainly composed of a pressing block, a bottom plate, a surrounding plate and a mold core. Since the opening size and the bottom width size of the rectangular groove are very small, the taper is also small, and the groove depth of the rectangular groove is often about 15cm or even deeper, it is difficult to ensure that the mold core is smoothly ejected along the direction of the product opening during demolding. Therefore, it is inevitable to touch the inner corners of the product groove during demolding, causing internal defects and capillary cracks in the product, and even longitudinal cracking of the product, which will inevitably affect product quality and production efficiency, and cause potential risks in the use of refractory bricks. The existing mold structure cannot meet the above molding requirements. Utility Model Content
[0003] The utility model aims to provide a refractory brick forming mold with a rectangular groove, which can effectively solve the cracking problem caused by the collision of the mold core block with the inner wall of the brick when the refractory brick with the rectangular groove is demoulded.
[0004] The utility model adopts the following technical solutions to solve the above problems:
[0005] A refractory brick forming mold with a rectangular groove, the refractory brick forming mold has a bottom plate, and a core block is placed on the bottom plate; the core block is a combination, that is, the core block includes a core I, a core III and a core II located between cores I and III; the cross-sectional shape of core II is an isosceles trapezoid; the cross-sectional shapes of cores I and III are both right-angled trapezoids; the larger bottom surface of core II is provided with bolt holes for connecting with bolts during demoulding; square edges are fixed on the bottom plate; the square edges are clamped on both sides of the lower part of the core block; the core block is located on the inner side of an outer mold sleeve, and a surrounding plate is provided between the core block and the outer mold sleeve; the surrounding plate is tightly attached to the inner side of the outer mold sleeve, and the lower end of the surrounding plate is connected to the bottom plate.
[0006] The bottom plate is an L-shaped plate with a protrusion at one end.
[0007] The utility model discloses a refractory brick forming mold with a rectangular groove. By arranging the mold core block as a combined structure, the collision of the mold core block with the inner wall of the refractory brick during demoulding is greatly reduced, and the efficient demoulding of the refractory brick with the rectangular groove is effectively realized. The operation is simple, and the product quality and production efficiency are improved. BRIEF DESCRIPTION OF THE DRAWINGS
