Background
A vibration molding machine for carbon products, wherein a paste obtained by mixing a solid material and a liquid binder in a mold box is formed into a carbon product having a predetermined outer shape by vibration molding. The gas such as flue gas and air in the paste is fully discharged to reduce the generation of cracks in the carbon block and improve the density of the carbon block, and the method has great significance for improving and ensuring the quality of the vibration molding carbon product. Although the traditional vibration forming machine also considers that a sealing cover and a vacuum extractor are arranged at the upper part of the mould box, the mould box and the lower template are only in rigid contact, so that a tiny gap exists at the joint surface, and complete sealing cannot be realized; in the forming process, if the lower template is stuck, the sealing tightness is aggravated, and the vacuum degree requirement required by the process cannot be met by the conventional vibration forming machine in the vacuumizing process due to the factors, so that the aims of improving the product quality and ensuring the product quality through vacuumizing cannot be fulfilled. Under the condition of poor sealing, due to the suction effect of the vacuum pump, air outside the mold box can be sucked into materials in the mold box from a gap between the mold box and the lower template, and the problems of uneven temperature inside the carbon block, product quality defects and the like can be caused. The lag of the vacuum-pumping technology has become one of the main technical obstacles restricting the quality improvement of the carbon products.
If the sealing strip is directly arranged below the die box body, the sealing material and the lower edge of the die box body form a step, so that the bottom edge of a product is likely to be flash in the vibration forming process, and the appearance quality is affected. In addition, the sealing strip is directly arranged below the mould box body, and the sealing effect cannot be achieved due to the fact that the lower mould plate is stuck to the mould.
Disclosure of Invention
The invention provides a vacuumizing mould box for a vibration forming machine, aiming at the problem that the vacuum degree of the mould box of the vibration forming machine cannot meet the technological requirements during vacuumizing.
The technical scheme for solving the technical problems is as follows: the vacuumizing mould box for the vibration molding machine is characterized by comprising a mould box body and a sealing sleeve box, wherein the sealing sleeve box is fixedly sleeved on the outer side of the mould box body, the sealing sleeve box is connected with the mould box body in a sealing mode, and a sealing strip is installed on the edge of an opening of the sealing sleeve box.
The sealing sleeve box is sleeved outside the mould box body, a certain distance is reserved between the sealing sleeve box and the mould box body, and one side of the opening of the sealing sleeve box and the bottom edge of the mould box body are on the same plane; or the sealing strip arranged at the edge of the opening of the sealing pouring jacket is on the same plane with the bottom edge of the mould box body or slightly exceeds 3-10mm after mould falling and compression. Therefore, when the sealing effect is achieved, the lower edge of the die box body and the lower template can be basically ensured to be in close planar contact. In the existing mold box, because the mold box body is in rigid contact with the lower template, gaps always exist between contact surfaces, and the gaps are hopefully sealed by paste materials loaded in the mold box in the past. And the sealing sleeve box is arranged on the outer side of the mould box for the reasons, and the sealing strip is arranged at the bottom of the sealing sleeve box to realize the sealing between the bottom of the mould box and the lower template.

Furthermore, the side plates are provided with connecting parting beads which are fixed on the reinforcing ribs. The connection division bars are arranged at the positions where the reinforcing ribs are parallel and corresponding, and the spacing between the sealing sleeve box and the side wall of the die box body can be further increased by the sealing division bars, so that the regulation and control effects are achieved. The thickness may be set as appropriate as necessary.
Furthermore, the outer side wall of the mould box body or the sealing sleeve box is provided with a positioning pin, and the vibration platform is provided with a positioning sleeve matched with the positioning pin. The positioning pin and the positioning sleeve are placed at accurate positions when the mold box is placed, and can prevent the mold box from horizontally displacing in vibration.
