With reference to Fig. 1, a kind of fine tuning structure of side core-pulling hold down gag, including the dynamic model 1 and the cover half 2 of downside of upside, institute
State dynamic model 1, the side of cover half 2 and be provided with side core-pulling 3, on the downside of the cover half 2, be provided with installing plate 4, arrange on the installing plate 4
There is fixation to barocline seat 5, the fixation seat 5 that baroclines is provided with inclined-plane towards at 3 side of side core-pulling, the fixation is baroclined the inclined-plane of seat 5
On be provided with baroclinic block 6, baroclinic block 6 can ensure that side core-pulling 3 stands fast in casting.The fixation is baroclined the inclined-plane and tiltedly of seat 5
It is provided between briquetting 6 for adjusting the adjustment bolt 7 of baroclinic block 6.
In real work, reference Fig. 1, the activity in the presence of associated mechanisms and power source of dynamic model 1 and side core-pulling 3, its
Middle dynamic model 1 is along above-below direction activity, and side core-pulling 3 is along the activity of 6 direction of baroclinic block.And after the completion of mould assembling action, side core-pulling 3
The cavity of closing is formed between dynamic model 1, cover half 2.The position that each part is accordingly fitted is die joint 11.When baroclinic block 6 and side
When the gap length at seal face that core pulling 3 is formed is suitable, dynamic model 1 and 3 matched moulds of side core-pulling just can in place, and at die joint 11
Gap also very little, now, the aluminium alloy castings geomery produced can be ensured compliance with requirement, and die joint 11
Feather overlap is also less, disclosure satisfy that production requirement.But in actual production, because being filled by single mold machining accuracy, mould
Impact with factors such as precision, thermal expansion, thermal deformations, the appropriate clearance between briquetting 6 and side core-pulling 3 at seal face on-fixed
Constant, this is just can to adjust angle, the position of baroclinic block 6 by adjusting adjustment bolt 7, and then adjustment briquetting 6 is taken out with side
Gap between core 3 at seal face.
Further embodiment, with reference to a kind of fine tuning structure of side core-pulling hold down gag of Fig. 1, Fig. 3, wherein referred to herein
" embodiment " refers to special characteristic, structure or the characteristic that may be included at least one implementation of the application.In this specification
" in the embodiment " that middle different places occur not refers both to same embodiment, nor individually or selectively with other realities
Apply the mutually exclusive embodiment of example.Embodiment includes the dynamic model 1 of upside and the cover half 2 of downside, the dynamic model 1, the side of cover half 2
Side core-pulling 3 is provided with, installing plate 4 on the downside of the cover half 2, is provided with, the fixed seat 5 that baroclines on the installing plate 4, is provided with, it is described
The fixation seat 5 that baroclines is provided with inclined-plane towards at 3 side of side core-pulling, the fixation barocline seat 5 inclined-plane on be provided with baroclinic block 6, institute
State fixation barocline seat 5 inclined-plane and baroclinic block 6 between be provided with for adjusting the adjustment bolt 7 of baroclinic block 6, the adjustment bolt
