Abstract
The utility model belongs to the technical field of a sand box, relating to a mould sand box. One end of two frames is hinged by a connector, and the other end is locked to form a quadrangular body. The outer surfaces of two opposite edges of the quadrangular body are provided with handles, and the outer corners of the frames are in arc transition. The utility model has the advantages of simple structure, integral structure, high precision of molten cast, low cost, convenient conveying and energy source saving, and is made of a plastic material.
Description
Technical field
The utility model belongs to the sandbox technical field, refers in particular to a kind of mold flask.
Background technology
The lost foam casting technology is simple because of having operation, the efficient height, advantages such as cost is low, at home and abroad obtained in recent years using widely, sandbox is one of necessary tool in the lost foam casting technology, the material majority of sandbox in the market is timber or cast iron, just very heavy when needing to produce large-scale or medium-sized foundry goods like this, need carry out split to sandbox, common have two-part mo(u)lding or a three-cavity moulding, no matter two casees or three-cavity moulding, they all are that artificial naked eyes position in mould assembling, assist with common apparatus again, this structure is greatly, on in the time of on the medium-sized foundry goods, drag box squeezes easily and bumps, get rid of head, situations such as mould shift had so not only wasted time but also had influenced the dimensional accuracy of foundry goods, even caused that foundry goods scraps, and the sandbox firmness of making of timber is not high, splits easily.
Summary of the invention
The purpose of this utility model provide a kind of simple in structure, firmness good, in light weight, with low cost, the high a kind of mold flask of foundry goods precision that casting is come out.
The purpose of this utility model is achieved in that
A kind of mold flask, an end of two frameworks is by hinged, the sealed formation quadrangle of the other end body of connector, and the outer surface of quadrangle body two opposite edges is provided with handgrip.
As preferably, the outer corner arc transition of described framework, described two frameworks are two independently integral structures.
As preferably, describedly sealedly be: the other end of a framework is provided with breach, and the other end of another framework is provided with and the projection that can insert and be full of breach, and projection is provided with pivot pin, and the lock dog with the projection equal thickness is installed on the pivot pin.
As preferably, described framework and lock dog are made with plastic material.
As preferably, described handgrip can be external or built-in on frame outer.
The outstanding compared to existing technology advantage of the utility model is:
1, two frameworks of the present utility model adopt two independently integral structures, and corner makes its sound construction, good stability by arc transition;
2, the utility model adopts recycled plastics material to make, and can the discarded object of plastics class rationally be utilized the low and energy savings of cost; Sandbox made of plastic is not only in light weight, convenient in carrying, and the foundry goods precision height that comes out of the smooth feasible casting of the inner surface of sandbox;
3, the utility model as long as rotate switch block with regard to separable sandbox and mould, makes foundry goods convenient to remove after the foundry goods moulding.
Description of drawings
Fig. 1 is a locking of the present utility model back structural representation;
Fig. 2 is the structural representation before the locking of the present utility model.
The specific embodiment
The utility model is further described with specific embodiment below in conjunction with accompanying drawing, referring to Fig. 1-2:
A kind of mold flask, an end of two frameworks 10,20 is by connector 30 hinged, the sealed formation quadrangle of other end bodies, and the outer surface of quadrangle body two opposite edges is provided with handgrip 40.
The outer corner arc transition of above-mentioned framework 10,20, described two frameworks 10,20 are two independently integral structures.
Above-mentioned sealedly be: the other end of a framework 20 is provided with breach 21, and the other end of another framework 10 is provided with and the projection 11 that can insert and be full of breach 21, and projection 11 is provided with pivot pin, and the lock dog 12 with projection 11 equal thickness is installed on the pivot pin.
Above-mentioned framework 10,20 and lock dog 12 usefulness plastic materials are made.
Above-mentioned handgrip 40 can be external or built-in on the outer surface of framework 10,20.
Use of the present utility model: behind the position of alignment projection 11 and breach 21, turn lock dog 12, the lock dog 12 and the end face of framework 20 are tightly fitted, in the cavity of sandbox, carry out operations such as moulding, cast again, after finishing the cast operation, turn on lock dog 12, slight shake sandbox both can make the inner surface of interior mould of cavity and sandbox break away from.
The foregoing description only is one of preferred embodiment of the present utility model; be not to limit protection domain of the present utility model according to this; so: all equivalences of doing according to structure of the present utility model, shape, principle change, and all should be covered by within the protection domain of the present utility model.
