Description
Technical field
The present invention relates to a kind of automatic moulding machine, specifically a kind of processing ratio of height to diameter is big, big platform difference product lower center
Presser device.
Background technology
With social development, Mechanical Manufacturing Enterprises gradually replace artificial trend with automatization, more and more set automatically
It is standby to be applied to numerous job shops.Automatic moulding machine is also one of them, and is favored by vast foundry enterprise.
Foundry goods or mould need to be obtained through filling, compacting, wherein filling, charging quantity, compacting, amount of compaction are to be related to
Can mould meet the important indicator of requirement, filling definition, by pressing plate and sandbox relative movement in template, sandbox and pressing plate it
Between formed confined space after, from blasting unit to this space penetrate sand process cry fill.Charging quantity is defined, and equipment is in the state of filling
Upper lower platen leaves the vertical dimension of template top and bottom, is charging quantity.Compacting definition, pressing plate is made to dredging in sandbox by oil cylinder movement
The sand pressurization of pine, so that the process that sand base density is improved in sandbox is compacting.Amount of compaction is defined, and pressing plate is moved from filling state
Compaction state is moved, the amount of short transverse change is amount of compaction.
But common forming machine principle such as Fig. 2, the product big for ratio of height to diameter, or the product that step difference is big, in fig. 2 A
Drape forming density ratio is very big compared with B drape forming density differences, such as certain product height 150MM, filling sand height 300MM pressures
Real 50MM,
A-quadrant compression ratio δ 1==, a-quadrant density improves
B area compresses are than δ 2==, the raising of B areal concentrations。
In view of die wall and the factor that sand rubs B regions bottom density is improved less, so that ratio of height to diameter is big
Product on automatic modeling it cannot be guaranteed that sand base density difference is too big after molding, or molding so that casting accuracy is uncontrollable,
And ratio of height to diameter is big or the poor big product of platform cannot be completed on automatic moulding machine.
