Technical field
Casting technology field is the utility model is related to, more particularly, to a kind of casting mould closer of more reorientations.
Background technology
Sand casting be one kind using sand as main Modeling Material, make the conventional casting techniques of casting mold, steel, iron and mostly
Number non-ferrous alloy casting can be obtained with sand mould casting method, and sand mold typically uses gravitational casting, also may be used when having particular/special requirement
Using the techniques such as low pressure casting, centrifugal casting, because the Modeling Material used in sand casting is cheap and is readily obtained, casting mold
It is simple to manufacture, single-piece production to casting, produces by batch and largely produce and adapt to, especially small lot and the production of big part
In, price advantage is especially prominent, therefore, the basic technology always in Foundry Production for a long time, in addition, sand mold refractoriness
Height, thus the higher material of such as copper alloy and ferrous metal fusing point also more uses this technique.
Traditional mould assembling positioning of existing sand casting typically uses following two modes：1. mould assembling cone is fixed on plate, in sand
The positioning hole of mould assembling is produced in type, sand mold closing pin is inserted during mould assembling and carries out sand mold mould assembling operation.This mould assembling side
Method is simple, easily operated, but because positioning hole, closing pin are all that sand mold makes, in operation because of the rocking of sand mold, right
Positive error etc. is all particularly easy to the abrasion for causing positioning hole, closing pin, causes sand mold to misplace, and ultimately forms lacking for casting mould shift
Fall into.The defects of this mould assembling mode is required caused by high casting for size is often fatal, make the percent defective of casting compared with
It is high.2. making latch structure on sandbox, template, latch is used during moulding, mould assembling.This method dimensional accuracy is high,
It is difficult and higher to the size and structural requirement of sandbox but operating process is complicated, it is appropriate only for the high production line of mechanization degree
Operation.
Utility model content
For the above situation, the defects of to overcome prior art, the utility model provides a kind of castings of more reorientations and closed
Case apparatus, effectively solve the problems, such as that existing mould closer position inaccurate, unreliable and dimensional accuracy be not high.
Its technical scheme solved is that the utility model includes cope and drag box, and the cope lower surface is provided with
Columnar projections, the bottom of columnar projections are provided with taper locating piece, and drag box opens up grooved hole, vertical sliding is provided with slotted eye
Rack, rack upper end are fixed with button, and button is provided with the taper positioning hole for taper locating piece, and the engagement of rack lower end is with teeth
Wheel, gear are fixed through gear shaft, and the right-hand member of gear shaft is fixed with first bevel gear, and first bevel gear right-hand member is engaged with the second cone tooth
Wheel, second bevel gear are fixed in slotted eye through rotary shaft, and rotary shaft is provided with spiral helicine cam path, is additionally provided with and can erect in slotted eye
The support frame directly slided, the upper surface of support frame is concordant with drag box upper surface, and the upper end of rotary shaft is inserted into support frame, branch
Bearing pin is provided with support, bearing pin is inserted in cam path, is formed rotary shaft and is rotated the structure for driving support frame to rise, cope is set
There is cavity, support frame is slidably inserted in cavity.
The utility model structure novelty, cope and drag box with during, can realize multiple positioning in mould assembling, fixed
Position precision is high, and accurate positioning, reliability is high, and when one of positioning appearance is worn or damaged, another positions remaining
Positioning can also continue to ensure mould assembling positioning, be not in that mould assembling effect is poor, the problem of casting mould shift occur.
