Description
Technical field
The utility model relates to sand casting technical field, is specially a kind of sand mold casting device preventing mould shift.
Background technology
Sand casting---in sand mold, produce the casting method of foundry goods.Steel, iron and most of non-ferrous alloy casting all can obtain with sand mould casting method.The Modeling Material used due to sand casting is cheap and easy to get, and Casting mold manufacturing is easy, and to the single-piece production of foundry goods, produce by batch and produce in a large number and all can adapt to, for a long time, be the basic technology in Foundry Production always.Sand casting is low than other casting method cost, production technology is simple, with short production cycle.So be all by clay green-sand explained hereafter as the foundry goods such as engine cylinder block, cylinder head, bent axle of automobile.Consider again when wet type can not meet the demands to use clay-bonded sand surface drying sand mold, dry sand mold or other sand mold.The casting weight of clay green-sand casting can from several kilograms until tens kilograms, and the foundry goods that clay dry type is produced can weigh tens tons.Because sand casting has above advantage, so it applies more and more extensive in foundiy industry.
General on the production line of sand casting, upper drag box and template matched moulds again after separating, then be delivered in casting machine by conveyer belt, may have in this process and necessarily jolt, especially for the foundry goods of simple shape, such foundry goods does not generally have too complicated close-over, does not have close-over directly to coordinate, and upper nowel ensures relative position by the direct frictional force of contact surface completely.But under this working condition of jolting, be easy to the situation (namely relative position produces deviation) occurring drag box mould shift, cause foundry goods to occur serious quality problems.
For this defect, number of patent application be 201520372237.2 Chinese patent disclose a kind of high accuracy mould assembling device for sand casting, comprise mould assembling cover I, mould assembling cover II, reed and guide pillar, described mould assembling cover I has the first inner chamber, described first inner chamber upper end closed, described first inner chamber lower end has opening, described reed is arranged around described first inner chamber for one week, and near the opening of described first inner chamber lower end, described reed is circular ring, the cross section of described reed is semi-cylindrical hill shape, described mould assembling cover II has the second inner chamber, described second inner chamber upper end has opening, described second inner chamber lower end closed, described guide pillar is provided with in described second inner chamber, described guide pillar is divided into epimere, interlude and hypomere, described guide pillar hypomere is fixedly connected with described second inner chamber lower end, described guide pillar interlude has the groove holding described reed, the accurate positioning of a kind of high accuracy mould assembling device for sand casting of the utility model, reliable, can foundry goods not mould shift be ensured and dimensional accuracy is high.
But above structure is mainly used in the anti-mould shift of sandbox, and also little for the Anti-dislocation effect of inner close-over, and also adopt above-mentioned structure, upper drag box, separately time, often occurs blocking owing to there is mould closer, needs to take could separate more energetically.
Utility model content
The technical problem that the utility model solves is to provide a kind of sand mold casting device preventing mould shift, thus solves the problem in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
A kind of sand mold casting device preventing mould shift, comprise cope, cope match plate and drag box, mould board, described cope coordinates with described cope match plate and makes close-over, and described drag box and described mould board coordinate and make lower close-over, described upper close-over and lower close-over have the contact surface cooperatively interacted
The one side that described cope match plate contacts with described upper close-over is provided with at least two column type boss, thus makes described upper close-over form corresponding pilot hole;
The one side that described mould board contacts with described lower close-over is provided with and described column type boss shrinkage pool one to one, thus makes described lower close-over form corresponding lead;
When described cope and described drag box mould assembling, the lead of described lower close-over is plugged in the pilot hole of described upper close-over;
Described lead and described pilot hole have a fit clearance.
In the utility model, as the preferred technical scheme of one, described cope match plate is provided with two column type boss, and described mould board also correspondence is provided with two shrinkage pools.
In the utility model, as the preferred technical scheme of one, described two column type boss are symmetricly set in the two ends of described cope match plate with the center line of described cope match plate.
In the utility model, as the preferred technical scheme of one, between described cope and described drag box, be provided with alignment pin.
In the utility model, as the preferred technical scheme of one, described alignment pin comprises the shank be arranged on described cope and the pin-and-hole be arranged on described drag box.
In the utility model, as the preferred technical scheme of one, the bottom of described pin-and-hole is provided with the cam of rotation, and described cam and described shank end are conflicted, and described shank can eject when rotating by described cam.
In the utility model, as the preferred technical scheme of one, described cam is provided with turning handle.
The utility model in use, cope match plate is joined the bottom being fastened on cope, and be sprinkled into molding sand wherein, molding sand is made into close-under the cooperation of described cope with described cope match plate, column type boss is provided with due in the one side that cope match plate contacts with described upper close-over, therefore go up close-over and can form corresponding pilot hole, mould board is joined the bottom being fastened on drag box, and be sprinkled into molding sand wherein, molding sand is close-under the cooperation of described drag box and described mould board makes, due in the one side that mould board contacts with lower close-over, shrinkage pool is set, therefore close-over is descended to form corresponding lead, because column type boss and shrinkage pool one_to_one corresponding, lead and pilot hole are also coordinated one by one, then by cope match plate, mould board is taken away, by cope and drag box mould assembling, now, the lead of lower close-over is plugged in the pilot hole of close-over, realize mutual location fit, prevent close-over from directly misplacing, same, also utilize alignment pin to position between cope and drag box, prevent mould shift, and utilize the cam arranged, effectively shank can be ejected, prevent alignment pin stuck, time saving and energy saving.
Owing to have employed above technical scheme, the utility model has following beneficial effect:
The utility model solves the phenomenon of close-in sand casting, sandbox dislocation effectively, and its structural principle is simple, is easy to realize, with low cost, does not affect the serviceability of template.
