Abstract

The utility model discloses a novel sand mould positioning device, which comprises an upper mould board and a lower mould board adaptive to the upper mould board and is characterized in that the upper mould board comprises an upper template and an upper model and a positioning pin sleeve which are arranged on the upper template, the upper mould board comprises a lower template and a lower model and a positioning pin shaft which are arranged on the lower template, the upper model is adaptive to the lower model, and the positioning pin sleeve 1 is adaptive to the positioning pin shaft. In the utility model, the positioning pin sleeve 1 and a positioning pin shaft model used for positioning are directly manufactured on the model board via the change of the structure of the model board, and in the shaping process, the positioning pin and the positioning hole of the sand mould are directly formed. Because the positioning pin and the positioning hole in the positioning method are manufactured along with the sand mould, error accumulation caused by the positioning pin and the positioning hole of a sand box is reduced, and the positioning is ensured to be accurate; and because the positioning pin and the positioning hole on the mould board are only contacted with the mould sand, the abrasion is smaller, and the service life of the mould is prolonged.

Description

A kind of novel sand mold positioner

Technical field

The utility model relates to a kind of novel sand mold positioner, be specially adapted to produce in batches the location of sand mold of the self-hardening sand casting (as resin bonded sand mould) of the craft of usefulness or machine moulding.

Background technology

For the foundry goods of producing in batches, no matter used sandbox is metal, still wooden, all is to use special shape mo(u)lding box generally speaking, and one pair of mould uses one pair of sandbox, and its main cause is exactly the orientation problem of sand mold.All be provided with positioner on every secondary sandbox, realize by the positioner of sandbox the location of sand mold.For single-sided pattern plate, the location by sandbox and template and then be the location of upper and lower sandbox at first, final mould assembling cast is to obtain qualified casting.When mould designs, not only to consider model position on template like this, but also will consider the location of template and sandbox, for final cast product, since the error of accumulation, the mould shift that always exists a little more or less, and serious causing scrapped.

The utility model content

It is to be that the utility model provides purpose, overcome the deficiency that exists on the prior art, and provide a kind of accumulation of error that causes by flask pin, location, hole that can reduce, the novel sand mold positioner of make its accurate positioning, being convenient to change, it is little to wear and tear, and has prolonged the service life of mould.

To achieve these goals, the technical solution of the utility model is: a kind of novel sand mold positioner, comprise cope match plate and with the suitable following template of cope match plate, it is characterized in that, described cope match plate comprises cope match-plate pattern and is arranged on last model and set pin sleeve on the cope match-plate pattern, described cope match plate comprises following masterplate and is arranged on down drag and alignment pin on the masterplate, described on model and drag suitable, described set pin sleeve and alignment pin are suitable.

According to above-mentioned a kind of novel sand mold positioner, wherein, described alignment pin and set pin sleeve are fabricated construction.

The utility model is directly produced location used set pin sleeve 1 and alignment pin model by changing the structure of template on template, direct alignment pin with sand mold, hole directly form when moulding in modeling process.Because alignment pin and locating hole in this localization method are together to make with sand mold, have the following advantages:

1, reduces the accumulation of error that causes by flask pin, locating hole, guaranteed accurate positioning.

2, come owing to alignment pin on template, hole only contact with molding sand, it is less to wear and tear, and has prolonged the service life of mould.

3, the alignment pin on mould, set pin sleeve can be made assembled, are more convenient for changing.

Among the figure: the 1-set pin sleeve; The last model of 2-; The 3-cope match-plate pattern; The 4-alignment pin; The 5-drag; The 6-lower bolster; The last sand mold die cavity of 7-; The 8-alignment pin; The 9-locating hole; Sand mold die cavity 11-goes up sand mold 12-core under the 10-; Sand mold under the 13-; The 14-die cavity.

The specific embodiment

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

Referring to Fig. 1 to 4, a kind of novel sand mold positioner, comprise cope match plate and with the suitable following template of cope match plate, described cope match plate comprise cope match-plate pattern 3 and be arranged on the cope match-plate pattern 3 on model 2 and set pin sleeve 1, this cope match plate comprises following masterplate 6 and is arranged on down drag 5 and alignment pin 4 on the masterplate 6, described upward model 3 is suitable with drag 5, and described set pin sleeve 1 is suitable with alignment pin 4.

Modeling process of the present utility model is: put sandbox after will descending template to place (as long as size is fit to, positioner need not arranged), inject self-hardening sand, treat that sand mold solidifies the back and deviates from sand mold from mould, then the top box sand mold 11 (as shown in Figure 5) that constituted of the alignment pin 8 that forms of last sand mold die cavity 7 that is formed by last model 2 and set pin sleeve 1 is placed on the flat ground surface then.

Placing cope on the template down, produce the locating hole 9 that the following sand mold die cavity 10 that formed by drag 5 and alignment pin 4 form and the nowel sand mold 13 (as shown in Figure 6) that constitutes by above-mentioned same method, then with locating hole 9 mould assemblys of the chiltern alignment pin that carries 8 with nowel sand mold 13, promptly go up sand mold 11 and merge the final whole sand mold (as shown in Figure 7) that forms mutually, be provided with the die cavity 14 and the core 12 that merge by last sand mold die cavity 7 and following sand mold die cavity 10 in the middle of it with following sand mold 12.

The utility model is directly produced location used set pin sleeve 1 and alignment pin 4 by changing the structure of template on template, direct alignment pin 8 with sand mold, locating hole 9 directly form when moulding in modeling process.Because alignment pin 8 and locating hole 9 in this localization method are together to make with sand mold, have reduced the accumulation of error that causes by flask pin 8, locating hole 9, guarantee accurate positioning.

And since on template 9 of alignment pins 8, locating hole contact with molding sand, it is less to wear and tear, and has prolonged the service life of mould.

Alignment pin 1, set pin sleeve 4 on mould can be made assembled, are more convenient for changing.

More than show and described basic 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 describes in the foregoing description and the specification just illustrates principle of the present utility model; under the prerequisite that does not break away from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
