Cold box molding core maker

Abstract

The invention discloses a cold core box forming core-making machine, comprising a stander part, a sand adding device, a movable ejection head, an upper pressure head and a sand ejection mechanism, a gas bag and a pipeline connection, a movable blowing cover with the function of an upper top core, a tray dolly, an upper core box lifting mechanism and a core box dolly with the function of a lower top core. When the equipment is provided with two sets of core boxes, core sand with two different process characteristics are added through a sand adding mouth as well as cut into ejection heads of two sand ejection areas, blowing covers of two blowing areas and a relatively independent sand ejection mechanism and a relatively independent blowing mechanism in a matched way, thus realizing the synchronous production of sand type or sand core in the same equipment and the independently adjustable process parameters. When the equipment is provided with a set of large core box, the mechanisms can be used in combination, thus being capable of preparing large sand types or sand cores.

Description

technical field [0001] The invention relates to an application of cold box technology, in particular to a cold box molding core making machine. Background technique [0002] Existing core making machine and molding machine are two kinds of different equipments, and both are incompatible. Especially for the promotion and application of cold box core molding technology, the original single-function core making machine and molding machine cannot meet the above requirements at the same time, and can only be realized by adding equipment. [0003] Existing core making machines or molding machines mainly include the upper moving mechanism, core box trolley, etc., which are composed of guide rails, trolley bodies, injection heads and blowing hoods that move on the guide rails through the trolleys. The blowing hood is supported on the same trolley body, the trolley is driven by a single power, and the injection head and the blowing hood move synchronously. The above structure determ...

AI Technical Summary

Problems solved by technology

After the core making and curing are completed, the sand core needs to be manually removed or cored by a coring car. Manual coring takes a long time and it is difficult to accurately locate the core by the coring car. These two aspects affect the core making efficiency and coring. stability

Because the injection head and the blowing hood are inseparable, there is no large room for movement on the equipment, so it is impossible to add two sets of injection heads and blowing hoods that can be controlled separately for simultaneous core making and molding
