Description
TECHNICAL FIELD
[0001] The utility model belongs to carbon production equipment technical field, specifically a kind of automatic lifting's forming mould spray device;It is applicable to carbon vibration forming product before mould wall surface spray. BACKGROUND
[0002] Forming procedure is the important link in the production process of carbon brick, and carbon brick vibration forming machine is the main equipment for producing carbon brick. In the vibration forming process, the paste overcomes the internal friction, cohesion and the friction between the paste and the mold wall. In order to make the surface of the green body after forming smooth, the mold needs to be heated. However, there is a certain friction between the wall surface and the product when the product is demolded in the mold, which may cause difficulty in demolding or demolding cracking. Therefore, the mold is lubricated by spraying oil before entering the feeding station, and the oil is sprayed on the side wall inside the mold, which plays a lubricating role between the product and the mold to reduce the friction coefficient of the mold. Each manufacturer uses the upper fixed spray nozzle spraying and manual smearing method to spray oil on the mold. Although this method improves the demolding difficulty, the oil sprayed by the upper fixed spray nozzle cannot be completely and uniformly sprayed on the working surface of the mold, and local defects may occur in the product in the un-sprayed position. Although the existing upper fixed spray nozzle spraying and manual smearing method has greatly improved the product quality, the local defects in the product still exist, and the above problems have not been completely solved. In addition, part of the upper fixed spray nozzle spraying uniformly sprays oil on the working surface of the mold by increasing the amount of oil sprayed, but oil may flow at the nozzle after increasing the amount of oil sprayed, oil may accumulate at the bottom of the mold, and the product mixed with the oil at the bottom may also appear sticky and uneven surface, which affects the quality. At the same time, the excess oil may produce smoke under the heating condition of the mold, which affects the air quality of the production environment. When manually smearing, uneven smearing, low work efficiency and safety hazards may occur, surface cracks may occur during demolding, and serious quality defects such as loose bottom of carbon brick product may occur.
