Abstract
The moulding of engine cylinder-body blank disposable mold releasing member and mould are cast the utility model discloses a kind of 465QF, the disposable mold releasing member includes being provided with connecting hole in inverted round stage, the inverted round stage, and connecting hole top is with inverted round stage top in same level.Compared with the existing, the utility model can be disposably stripped, and white clay need not be smeared again in follow-up mould assembling technique.
Description
Technical field
The utility model is related to the preparation of engine cylinder-body, and more particularly to a kind of 465QF castings engine cylinder-body blank is made
The disposable mold releasing member of type.
Background technology
In the moulding process for casting engine cylinder-body blank moulding, due to needing the formation process hole on molding sand during moulding
(the technique plug of the fabrication hole and jacket core matches), therefore loose pattern moulding is used during moulding, the structure of loose piece is shown in Fig. 3, loose piece
Be made up of round platform 1, jack 2 offered in round platform 1, before moulding, by the jack 2 of loose piece on the pin 4 of the mould 3 shown in Fig. 4.
But there is following defect in the moulding：1st, loose piece need to be laid by making size external form every time, and the time is 4-5 seconds, and 2, molding sand
Filling up after external form needs to take out loose piece, and the time is 2-3 seconds.3rd, the technique bore dia after being madeSize external form during mould assembling
Fabrication hole position surrounding need to smear white clay, and the time is 20-30 seconds；And smear and easily block up fabrication hole exhaust position during white clay
Firmly, cause exhaust not smooth, produce stomata；And body operation is bended forward when smearing fabrication hole white clay repeatedly, labor intensity is big, it may appear that white clay
The risk of die cavity is pierced, causes fabrication hole to press from both sides white clay, product rejection.
Utility model content
One of the purpose of this utility model is that a kind of 465QF casting engine cylinder-body blank moulding of offer with disposably
Mold releasing member, the disposable mold releasing member can be disposably stripped, and white clay need not be smeared again in follow-up mould assembling technique.
Technical scheme is：A kind of 465QF casts the disposable mold releasing member of engine cylinder-body blank moulding, described disposable
Mold releasing member includes being provided with connecting hole in inverted round stage, the inverted round stage, and connecting hole top is with inverted round stage top in same level.
Preferably, the inverted round stage lower end is provided with cylindrical nib, cylindrical nib diameter is less than inverted round stage bottom
Diameter is held, cylindrical nib and inverted round stage longitudinal direction are concentric.
Preferably, offering thread groove on the connecting hole inwall.
Preferably, the inverted round stage top end diameter isCylindrical nib is a diameter of
Preferably, the disposable mold releasing member one-shot forming.
The two of the purpose of this utility model are to provide a kind of 465QF castings engine cylinder-body blank moulding mould.
Technical scheme is：A kind of 465QF casts and be provided with and weigh on engine cylinder-body blank moulding mould, the mould
Profit requires the screw that described thread groove is engaged.
Compared with prior art, the beneficial effects of the utility model are：
The utility model can be disposably stripped in formative technology, need not be removed in continuous processing, using rise
Come very convenient, and white clay need not be smeared again in follow-up mould assembling technique.

Fig. 3 is background technology loose piece overall structure diagram；
Fig. 4 is background technology mould structure schematic diagram.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Embodiment 1
As Fig. 1, a kind of 465QF cast the disposable mold releasing member of engine cylinder-body blank moulding, including inverted round stage 1, be somebody's turn to do
Connecting hole 2 is provided with inverted round stage 1, the top of connecting hole 2 is offered with the top of inverted round stage 1 in same level, the inwall of connecting hole 2
Thread groove 3.
The lower end of inverted round stage 1 is provided with cylindrical nib 4, and the diameter of cylindrical nib 4 is less than the bottom diameter of inverted round stage 1,
Cylindrical nib 4 and the longitudinal direction of inverted round stage 1 are concentric.
The top end diameter of inverted round stage 1 isCylindrical nib 4 is a diameter of
Disposable mold releasing member be able to can also be fixedly connected or detachably with one-shot forming, inverted round stage 1 with cylindrical nib 4
Connection.
Embodiment 2
As Fig. 2, a kind of 465QF cast engine cylinder-body blank moulding mould, including die ontology 5, the die ontology 5
On be provided with the screw 6 being engaged with Fig. 1 thread groove 3.
A kind of embodiment 3,465QF casts the casting method of engine cylinder-body, comprises the following steps：
Step A：
1. molding and with molding sand, is provided with the screw 6 in Fig. 2 on the mould.
2. the connecting hole 2 of Fig. 1 disposable mold releasing member is enclosed within screw 6 and screwed.
3. moulding and the demoulding, disposable mold releasing member is deviate from out of blank moulding simultaneously with mould, transversal outside blank moulding
Formed on face a diameter ofFabrication hole.Because same mould is stripped together, thus it is disposable when working again
Mold releasing member need not be reinstalled in moulding.
Step B：There is jacket core plug on the preparation of jacket core, jacket core.Step B is synchronous with step A to be prepared.
Step C：By moulding and jacket core mould assembling, jacket core plug insertion process hole is not required to smear white clay around fabrication hole.
Step D：Cast, obtains 465QF casting engine cylinder-body blanks after cooling.
