Abstract
The core mold that sand is vented is penetrated the utility model discloses a kind of improve, including the first side form block, the second side form block, upper module, lower module, upper cylinder half cup, lower cylinder cup, insert；The position that insert is set can be the position of more difficult shaping in whole cavity to provide precision higher forming surface by the higher insert of separately fabricated precision.Due to first penetrate sand launder, second penetrate sand launder penetrate sand while first inserting the position of the i.e. more difficult shaping in insert both sides, it is from inside to outside to make entirely to penetrate sand shaping, it will first be tamped in the segment set of more difficult shaping, outwards residual gas is extruded by first, second, third exhaust duct simultaneously again, so that more difficult shaping position can improve the core yield of shaping easily full of shaping.
Description
Technical field
The utility model belongs to mould applications, especially core mold.
Background technology
By penetrating sand formation core into mould, when penetrating sand, sand can be filled up rapidly in a mold for core mold in die cavity,
Discharged at the venting plug in air meeting slave module in die cavity.And after the completion of sand is penetrated, due to sand core structure problem, some parts
Shape sand can not reach or it is local produce vapour lock, die cavity can not complete stamp.Especially in die cavity some due to space it is limited
And sand it is more difficult by and tamp the position of shaping, this problem is more serious.Cause core shape to lack, cause core to scrap.
Therefore need a kind of new technical scheme to solve the above problems.
Utility model content
To overcome existing core to produce core defect problem because of structure design, the utility model purpose is to be offer one
Plant to be vented and penetrate when being convenient for penetrating sand and core mold can be fully enriched after sand.
To reach above-mentioned purpose, the utility model can be adopted the following technical scheme that：
It is a kind of improve penetrate sand exhaust core mold, including the first side form block, the second side form block, upper module, lower module, on
Cylinder cup, lower cylinder cup, insert；The upper module is covered in above the first side form block and the second side form block, and lower module is located at the first side
Below module and the second side form block；Cavity is formed between the first side form block, the second side form block, upper module, lower module, it is described
Upper cylinder half cup, lower cylinder cup, insert are respectively positioned in cavity；And lower cylinder cup is located on lower module, insert is carried on lower cylinder cup, upper cylinder half cup
It is carried in insert；Formation is passed directly into first of insert side in cavity and penetrates sand launder in the upper module, the first side form block, on
Formation is passed directly into second of insert opposite side in cavity and penetrates sand launder in module, the second side form block；It is common in upper module, upper cylinder half cup
Form the first row air flue of connection cavity；The second row air flue of directly connection cavity is collectively forming in lower module, lower cylinder cup；Lower mould
The 3rd exhaust duct of directly connection cavity is collectively forming in block, lower cylinder cup, insert.
Beneficial effect：The beneficial effects of the utility model are, by setting insert to be located between lower cylinder cup and upper cylinder half cup
Facilitate integrally-built installation and the setting of exhaust duct；The position that insert is set can be the position of more difficult shaping in whole cavity
So as to provide precision higher forming surface by the higher insert of separately fabricated precision.And by first row air flue,
Second row air flue, the 3rd exhaust duct make the residual gas for penetrating sand space-time intracavitary upward, downward simultaneously by each exhaust duct short time
Exclude.Also, due to first penetrate sand launder, second penetrate sand launder penetrate sand while first inserting the position of the i.e. more difficult shaping in insert both sides,
It is that from inside to outside, first will be tamped in the segment set of more difficult shaping to make entirely to penetrate sand shaping, then outwards simultaneously by first, the
2nd, the 3rd exhaust duct extrudes residual gas, so that more difficult shaping position can improve the core of shaping easily full of shaping
Yield.
