Abstract

The utility model discloses a novel V-process casting mold and relates to the field of aluminium alloy casting technologies. The novel V-process casting mold comprises a vacuum box, wherein a mold plate is arranged on the vacuum box; a vacuum pumping opening is formed in one side of the vacuum box; a mold is mounted on the mold plate; a foam module is adhered to the mold through a double faced adhesive tape. Through the novel V-process casting mold, the manufacture of a wood core box is cancelled; the foam cost is far less than wood cost; a module manufacturing process is simpler than a core box manufacturing process, so that the casting process is simplified and the production cost is reduced.

Description

A kind of novel V method casting mould

Technical field

The utility model relates to aluminium alloy casting technology field, is specifically related to a kind of novel V method casting mould, be specially adapted to add core the casting of V method.

Background technology

Because the casting of V method has, the visual quality of casting is good, precision is high, reduce environmental pollution, improve the advantages such as shopwork environment, and it was being developed in recent years rapidly.But V method casting technique is only applicable to foundry goods simple in structure, to be easy to the demoulding, some producers are for the position being difficult for or cannot the demoulding, adopt the method for lower resin sand core, its method therefor is, according to shape and feature that cannot demoulding region, make wooden core box, then the resin sand that contains binding agent is put into core box, after resin sand solidifies, take off core box and obtain resin sand core, when casting, resin sand core is fixed on sand mold, after strand casting pickup, resin sand core is cut a hole to broken taking-up, can cast out cannot demoulding region shape.Its shortcoming is: 1. make wooden core box, increased Production Time and the cost of raw material is higher; 2. the binding agent of resin sand core can only use once, and also can produce smog and penetrating odor under the condition of high temperature, pollutes working environment; Though 3. resin sand can be reused, pulverize cost higher; 4. strand is inner while taking out resin sand core, resin sand core has certain intensity and strand built-in function space is less, causes that to take out difficulty large, labor intensive and strengthened cleaning work amount; 5. because resin sand core is fixed on sand mold, in the time that solution injects, easily displacement and translating into, causes foundry goods to scrap, the yield rate of reduction foundry goods.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of novel V method casting mould, and the Casting Principle of evaporative pattern is combined with the casting of V method, interferes the shape of the demoulding to be made of foam by mould.

Technical problem to be solved in the utility model realizes by the following technical solutions:

A kind of novel V method casting mould, comprises a vacuum tank, and described vacuum tank is provided with template, and described vacuum tank one side is provided with vacuum orifice, on described template, mould is installed, and on described mould, is bonded with foam module by double faced adhesive tape.

Described mould outside is covered with facial mask, and described foam module is bonded in facial mask outside.

Described foam module is foam mold.

The beneficial effects of the utility model are:

1, cancelled the making of wooden core box, the cost of foam is well below timber, and module making technique will be lower than the manufacture craft of core box, thereby simplified casting technique and reduced production cost;

2, cancel resin sand and binding agent and used, when having saved production cost greatly, also improved working environment;

3, siphon away because foam module is vaporized, without any residue, reduced cleaning work amount and alleviated labour intensity;

4, because module is tightly wrapped up by sand, can not produce displacement and translate into, improve the yield rate of strand.

Detailed description of the invention

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

As shown in Figure 4, a kind of novel V method casting mould, comprise a vacuum tank 4, vacuum tank 4 is provided with template 5, and vacuum tank 4 one sides are provided with vacuum orifice, and mould 2 is installed on template 5, on mould 2, be bonded with foam module 3 by double faced adhesive tape, mould 2 outsides are covered with facial mask 6, and foam module 3 is bonded in facial mask 6 outsides, and foam module 6 is foam mold.

As shown in Figure 1, existing product 1 needs to make, and now casts with mould:

1. require to carry out technological design according to products characteristics and casting, because the groove place of both sides, product bottom cannot molding, can not directly cast out by V method, so will in mould 2, hinder the both sides boss of molding make foam module 3, and at mould in the upper installation site (as Fig. 2) that indicates foam module 3;

2. mould 2 is fixed on the template 5 that is positioned at vacuum tank 4, then carries out clad can film 6 operations (as Fig. 3);

3., after overlay film finishes, foam module 3 use two-sided tapes are bonded in to mould marker location (as Fig. 4);

4. spray paint, oven dry, then overlaps cope 7, adds sand jolt ramming operation;

5. be then covered with notacoria 9, when dry sand 8 taken out by vacuum tight after, foam module 3 is by parcel tightly of dry sand 8 and cannot displacement (as Fig. 5);

6. play type stripping process, now foam module 3 can be along with sandbox 7 is lifted (as Fig. 5);

8. in the time that moulding finishes mould assembling cast, the high temperature of solution is vaporized foam module 3 and is replaced its position, and a small amount of residue that foam module 3 produces is sucked in sand by vacuum;

9. the pickup of unpacking, for foam module 3 and cannot demoulding position without doing any cleaning work, time saving and energy saving, after cleaning finishes, the strand that can obtain casting with this case.

More than show and described general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and description, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
