The utility model belongs to the technical field of lost foam casting, discloses a casting mould for magnesium metal refining kettles, and provides a vacuumizing casting mould which can reduce air holes in the bottoms of casting kettles and improve the casting quality of the refining kettles. According to the technical scheme, the casting mould for the magnesium metal refining kettles comprises an upper box and a lower box, the lower box is covered with the upper box and is a sand box, a plurality of vacuumizing tubes are arranged on the lower box, a plurality of pipelines are arranged at the bottom of the lower box, communicated with the vacuumizing tubes and respectively provided with a plurality of air extraction ports, a cavity is formed in the lower box body, and a lost foam casting mould is arranged in the cavity. According to the casting mould for the magnesium metal refining kettles, due to the adoption of vacuumizing lost foam casting, the quality of castings is improved, the air holes of the formed castings are absolutely avoided, the service life of the refining kettles is greatly prolonged, the production efficiency is improved, potential safety hazards are eliminated, and the production cost is lowered.

Description

A kind of metallic magnesium refining pot casting mould
Technical field
A kind of metallic magnesium refining pot of the utility model casting mould, belongs to Technology of EPC field.
Background technology
Magnesium metal smelting industry development is more late, just starts in the ascendant after the nineties.But technological progress aspect is always slower.In view of the particularity of magnesium metal smelting, the especially particularity of refining process and danger, and the quality of metallic magnesium refining pot never well promoted in magnesium industry, to producing, causes very large restriction and potential safety hazard.The quality problems of kier are mainly the bottom of a pan part, and conventional manufacture method is permanent casting, mainly relies on the natural pressure deaeration of molten steel, so the pore problem in foundry goods is difficult to get rid of completely.And magnesium metal smelting mainly relies on outside heated by gas and inner magnesium chloride solvent to smelt, and this two media corrodes very large to the inside and outside wall of kier, once occur that pore invades very soon and the rapid focus that expands, cause magnesium liquid to reveal, very person leads to great security incident.
Utility model content
The purpose of this utility model is: a kind of casting mould that vacuumizes is provided, reduces the pore in the casting pot the bottom of a pan, improve the castability of kier.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of metallic magnesium refining pot casting mould, comprise upper box and lower box, described upper box covers above lower box, described lower box is sandbox, on described casing, be provided with many vacuum-pumping tubes, the bottom of described casing is provided with many pipelines, described many pipelines are connected with a plurality of vacuum-pumping tubes, on described many pipelines, be provided with a plurality of bleeding points, in described lower box, be provided with die cavity, in described die cavity, be provided with disappearance mould.
As preferably, described vacuum-pumping tube is perpendicular to the upper surface setting of lower box.
As preferably, described lower box is square chest, and the quantity of described vacuum-pumping tube is 4, and described four vacuum-pumping tubes are separately positioned on four angles of lower box.
As preferably, described lower box is cylinder case, and described many vacuum-pumping tubes are uniform around cylinder Xiang center.
As preferably, on described upper box, be provided with cast gate, described cast gate is arranged on the center of upper box and extends to die cavity.
As preferably, described upper box is bolted on lower box.
As preferably, the material of described disappearance mould is expandable polystyrene.
The utility model compared with prior art has following beneficial effect: the utility model adopts and vacuumizes lost foam casting, before casting, will in casing, vacuumize, like this in casting, in sandbox, do not have air, and when casting, continue to vacuumize, gas in casting liquid is taken away, avoid casting in liquid and entrain into gas and form sand holes, improved the quality of foundry goods, foundry goods after moulding does not have pore completely, substantially restricted the bottleneck problem of metallic magnesium refining, greatly extended the service life of kier, improved production efficiency, eliminated potential safety hazard, reduced production cost.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail.
Fig. 1 is the internal structure schematic diagram 1 of a kind of metallic magnesium refining pot of the utility model casting mould.
Fig. 2 is the internal structure schematic diagram 2 of a kind of metallic magnesium refining pot of the utility model casting mould.
In figure: 1 is upper box, 2 is lower box, and 3 is vacuum tube, and 4 is pipeline, and 5 is bleeding point, and 6 is die cavity, and 7 is cast gate.
The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now, the schematic diagram of accompanying drawing for simplifying, basic structure of the present utility model is only described in a schematic way, so it only shows the formation relevant with the utility model.
As shown in Figure 1-2, a kind of metallic magnesium refining pot casting mould, comprises upper box 1 and lower box 2, upper box 1 covers above lower box 2, lower box 2 is square sandbox, is vertically installed with 3, four vacuum-pumping tubes 3 of 4 vacuum-pumping tubes uniform around cylinder Xiang center on lower box 2.The bottom of lower box 2 is provided with many pipelines 4, and many pipelines 4 are connected with four vacuum-pumping tubes 3, are provided with a plurality of bleeding points 5 on many pipelines 4, are provided with die cavity 6 in lower box 2, are provided with the disappearance mould of expandable polystyrene in die cavity 6.Wherein, upper box 1 is bolted on lower box 2, is provided with cast gate 7 on upper box 1, and described cast gate 7 is arranged on the center of upper box 1 and extends to die cavity 6.
Before casting, the sand mold of lower box 2 is built, put into evaporative pattern, between upper box 1 and lower box 2, be bolted, then detach the gas in casing, after casing is evacuated, from the cast gate 7 of upper box 1 center, start casting, evaporative pattern melts, and continues to vacuumize simultaneously, air in casting liquid is detached, avoid generation pore in the foundry goods after moulding.
The foundry goods casting out by the utility model, at the bottom of eliminating the kier of airhole completely, has solved the bottleneck problem of restriction metallic magnesium refining substantially, greatly extended the service life of kier, improve production efficiency, eliminated potential safety hazard, reduced production cost.
By reference to the accompanying drawings embodiment of the present utility model is explained in detail above, but the utility model is not limited to above-described embodiment, in the ken possessing those of ordinary skills, can also under the prerequisite that does not depart from the utility model aim, make a variety of changes.For example, the lower box 2 in the utility model also can be cylinder case, and many vacuum-pumping tubes 3 are uniform around cylinder Xiang center.
