Description
Technical Field
The utility model relates to a casting equipment technical field.
Background
The sand mold is formed by casting sand, bentonite, coal powder and other materials under the action of high extrusion force of a molding machine, high-temperature molten iron is injected into a cavity inside the sand mold, and a casting to be obtained is obtained after cooling. Because the molding machine is used for continuous production molding, sand mold conveying needs to be synchronous with the molding machine so as to ensure continuous production. There are two main ways of delivery: clamping synchronous conveying and supporting synchronous conveying. The clamping synchronous conveying is suitable for a small moulding line with the sand mould size below 800x600mm, and the supporting synchronous conveying is suitable for sand mould conveying with the sand mould size larger than 800x600 mm. Along with the requirement of improving the production efficiency of the casting industry, originally, large castings (such as well rings and well lids) which are manually operated and static pressure line operated are gradually transferred to a vertical molding line for production, the requirement of the supporting synchronous conveyor is increased, the precision and speed requirements are higher and higher, and the structure and performance of the supporting conveying at present can not meet the production requirement.
The static strip of the existing supporting synchronous conveying device is static, and the moving strip completes the up-and-down lifting and the front-and-back movement. The working process is as follows: (1) the movable strip rises to drive the sand mould to rise, and the sand mould is separated from the static strip; (2) at the moment, the driving mechanism pushes the movable strip to drive the sand mould to convey forwards by a distance of one sand mould; (3) after the sand mold is in place, the movable strip descends, the sand mold falls onto the static strip, and the movable strip continues to descend below the static strip; (4) the driving mechanism drives the movable strip to retreat in place, and the sand mold is fixed on the static strip. The four actions are a cycle, and the cycle is matched with a molding machine to finish the continuous molding conveying production of the sand mold. The above-mentioned conveying device has the following disadvantages: the moving strip rises to drive the sand mould to rise, and the moving strip falls to drive the sand mould to fall. Because the whole molding line consists of the molding machine, the supporting and conveying machine and the belt cooling machine, the whole line sand molds form a long string. The sand mould on the bottom plate of the molding machine and the sand mould on the conveying belt cannot ascend and descend along with the sand mould on the supporting and holding conveyor, and the sand mould on the supporting and holding synchronous conveyor, the sand mould on the bottom plate of the molding machine and the sand mould on the conveying belt can be in vertical friction dislocation. Meanwhile, because the supporting and conveying are carried out for one sand mold at each time, the vertical staggered friction of each sand mold on the sand mold string is equivalent, the staggered box friction can damage a sand mold casting cavity, the sand mold falling due to friction can be remained in the casting cavity, and the casting can generate a series of defects such as staggered box, sand sticking and sand inclusion during pouring, so that the quality of the casting product is influenced. Therefore, increasingly stringent product quality requirements for the castings have not been met.
