Background technique
Core box is to need to equip using the important process arrived in Foundry Production, and core box structure designs and produces, direct relation
To core box service life, casting dimension accuracy and safety in production.
The manufacturing process of the type core of manufacture casting class workpiece are as follows: core sand is packed into core box；Cure process is carried out to core sand,
To obtain sand core；Core is played, i.e., is taken out sand core out of core box.The cure process of core sand can take self-hardening or other modes
Cure process.
Existing core box includes core box frame and core the bottom plate of the box body, and the two is detachably fixed connection.It will be blended when making sand core
Resin sand or water-glass sand (i.e. core sand) filling core box in, struck off after ram-jolt, after sand core solidification after overturning core box go out core, due to
There is higher intensity after resin sand, water-glass sand solidification, out core relative difficulty, needs to shake out by hitting core the bottom plate of the box body
Type, since hitting power is transmitted on sand core again by core the bottom plate of the box body, sand core power is very weak out, in addition on core box plane and
Sand core is in sustained height and does not go out core space, needs the strike by the long period, sand core can just fall off, as core box uses
The extension of time, hitting dynamics are also required to continue to increase, and deforming and cracking occur in various degree in core box, influence using.
In view of the above shortcomings, the designer, is actively subject to research and innovation, to found a kind of new structural core
Box makes it with more the utility value in industry.
