Abstract

The utility model discloses a common V method template. A connection line between pin holes on both sides of the V method template is used as a zero line for a horizontal center line and a longitudinal center line, a contact position between the zero line and the edge of the V method template is set to be a zero point, the zero point is used as the starting point, scale lines are respectively set by spacing 5mm from the starting point to both sides, and holes are formed in the edge of the V method template by spacing each scale mark. The common V method template has the advantages of simple structure and easy preparation. Besides, during use, positioning pins and the pin holes are used as the standard of the zero line by an upper template and a lower template, and the problem of the commonality of the template is solved.

Description

V method common template

Technical field

The utility model relates to a kind of V method common template, belongs to casting technology field.

Background technology

The casting of V method and lost foam casting also claim negative pressure casting, because the prefix " V " of getting English Vacuum mono-word is gained the name.It is different from traditional sand, and to cast maximum advantage be not use adhesive, the casting of V method is to utilize plastic sheeting sealing sandbox, by air in vacuum-pumping system extraction type, inside and outside casting mold, there is pressure differential, make dry sand closely knit, form required die cavity, vacuumize and make casting solidification through lower core, mould assembling, cast, remove negative pressure, molding sand thereupon defeated and dispersed and obtain foundry goods.

The casting of V method, has the following advantages with lost foam casting compared with traditional sand casting:

One, because it adopts that vacuum-assist pouring foundry goods sand holes pore is few, product packing is high, any surface finish, clear-cut, size be accurate;

Its two, efficient energy-saving cleaner production.Adopt V method and evaporative pattern technology can make dry sand recycle, need not baking type, consumption coal reduces, but due to long-term vacuum machine operation, power consumption has increased slightly, but reduce greatly dust, save human capital, make foundry work more effective, save labour and greatly reduce labour intensity, in casting process, pernicious gas is few, really realizes environmental protection and produces.

At present, V method cast article cast article compared with other techniques in outward appearance, inherent quality, size Control is more excellent, and production procedure is shorter, facilitates process control.Traditional template, generally without groove design, so in the time that multi-product mould is replaced, may misplace by upper and lower mould, causes foundry goods shift and dimensional discrepancy, finally causes the increasing of polishing amount and size to be scrapped.If adopt template of a product, in many kinds, when small batch is produced, will certainly increase investment in fixed assets, management difficulty is large in addition, takies a large amount of storage spaces.

Utility model content

The purpose of this utility model is: a kind of V method common template is provided, solves the technical problem of template versatility, thereby can effectively solve above-mentioned problems of the prior art.

The purpose of this utility model is to realize by following technical proposals: a kind of V method common template, zero point line with the pin-and-hole line using V method template both sides as cross central line and longitudinal centre line, the contact position, edge of zero point line and V method template is made as zero point, taking zero point as starting point, to both sides, spacing 5mm arranges graduation mark respectively, at interval of a graduation mark, a punching is set at the edge of V method template.

As further preferred embodiment, the length of described graduation mark is 50mm.

As further preferred embodiment, one, interval graduation mark arranges a long graduation mark.

As further preferred embodiment, the length of described long graduation mark is 70mm.

As optimal way, the diameter of described punching is 1mm, and the degree of depth is 2-3mm.

As optimal way, described V method template comprises cope match-plate pattern and lower bolster.

On the basis of conventional template, taking template center's line as zero point line, in upper and lower template, engrave graduation mark, minimum scale value is 5mm, location while facilitating mould to replace; The mid point zero line of cope match-plate pattern is taking alignment pin as benchmark, and lower bolster mid point zero line, taking pin-and-hole as benchmark, ensures that bolster zero line overlaps.

Compared with prior art, the beneficial effects of the utility model: the utility model V method common template simple in structure, preparation easily, when use, taking alignment pin and pin-and-hole as zero line benchmark, solves the problem of template versatility by upper and lower template.

Brief description of the drawings

Fig. 1 is the structural representation of the utility model V method common template.

In figure: 1-alignment pin, 2-guide pin hole, 3-longitudinal centre line, 4-cross central line, 5-graduation mark, the long graduation mark of 6-, 7-punching.

Detailed description of the invention

Below in conjunction with specific embodiment, the utility model is further described.

Disclosed all features in this description, or step in disclosed all methods or process, except the speciality and/or step of mutual repulsion, all can combine by any way, unless narration especially, all can be replaced by other equivalences or the alternative features with similar object,, unless narration especially, an embodiment in a series of equivalences of each feature or similar characteristics.

As shown in Figure 1, the zero point line of the utility model V method common template using the pin-and-hole line of V method template both sides as cross central line 4 and longitudinal centre line 3, the contact position, edge of zero point line and V method template is made as zero point, taking zero point as starting point, to both sides, spacing 5mm arranges graduation mark 5 respectively, and the length of described graduation mark 5 is 50mm; For the ease of identification, the length of graduation mark can also be other length, such as 60-80mm.One, interval graduation mark 5 arranges a long graduation mark 6, and the length of described long graduation mark 6 is 70mm, and for the ease of identification, the length of long graduation mark can also be other length, such as 90-120mm.Edge in V method template arranges a punching 7 at interval of a graduation mark 5, and the diameter of described punching is 1mm, and the degree of depth is 2-3mm.This punching is for installing with air chamber, as locking screw holes.Guide pin hole in described V method template plays location, ensures the effect that the upper and lower molded dimension of foundry goods is not offset.

This V method template comprises cope match-plate pattern and lower bolster, when use, taking alignment pin and pin-and-hole as zero line benchmark, solves the problem of template versatility by upper and lower template.

Preparation process of the present utility model is:

The first step, taking alignment pin or dowel hole and guide finger or guide pin hole as benchmark, first carves zero line.

Second step, taking zero line as starting point, carving respectively spacing to both sides is the graduation mark that 5mm, length are 50mm, at interval of a graduation mark 5, a long graduation mark 6 is set; The length of described long graduation mark 6 is 70mm.

The 3rd step, it is 1mm that every 10mm graduation mark descends diameter in a state of excitement with sample, the punching that the degree of depth is 2-3mm.

When use, the mid point zero line of the cope match-plate pattern of V method template is taking alignment pin as benchmark, and lower bolster mid point zero line, taking pin-and-hole as benchmark, ensures that bolster zero line overlaps, minimum scale 5mm.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all any amendments of doing within spirit of the present utility model and principle, be equal to and replace and improvement etc., within all should being included in protection domain of the present utility model.
