Description

Penetrating iron core casting magnesium alloy anode production mold

Technical Field

The utility model relates to a run through iron core casting magnesium alloy positive pole production mould belongs to magnesium alloy positive pole production technical field.

Background

The magnesium alloy sacrificial anode is mainly used for anticorrosion protection, is widely applied to anticorrosion of various steel structural facilities, electrical appliances and the like, and has the principle of protecting a cathode by the sacrificial anode.

The conventional cast magnesium alloy anticorrosive anode can only produce a non-penetrating iron core product inside the anode, large-scale rapid production of the cast magnesium alloy penetrating iron core product is not realized, and the defects of large sprue volume occupation ratio and high production process loss exist in the process of casting and producing the penetrating iron core anode in small batches. In addition, the existing casting production process mostly uses a mode of anode side feeding, has the defects of insufficient casting, cold shut and the like of products, and seriously influences the yield. And after casting, the side gate is not easy to remove, and a special numerical control device is needed in the removing process, so that the subsequent processing cost is high.

The existing mass-produced penetrating iron core anode can only be produced by an extrusion process, a blank with proper length and diameter is cast after a magnesium alloy ingot is remelted in the process, the blank is processed into a fine blank and then is heated to 420-500 ℃ for production by an extruder, and the energy consumption and the equipment cost are increased.

SUMMERY OF THE UTILITY MODEL

According to the not enough among the above prior art, the utility model discloses the technical problem who solves is: the through iron core cast magnesium alloy anode production die is provided, an extrusion mode is bypassed, a casting mode is used for producing an anticorrosive anode of the through iron core, and the problem existing in the existing cast magnesium alloy anticorrosive anode is solved.

Run through iron core casting magnesium alloy anode production mould, including cover half and movable mould, all be equipped with a plurality of corresponding cross-section semicircular in shape channels in cover half and the movable mould, channel one end on the cover half is equipped with the iron core constant head tank, the mould is still including pressing the iron core briquetting on the iron core constant head tank.

Furthermore, the fixed die is provided with a positioning pin, and the movable die is provided with a positioning hole matched with the positioning pin.

Preferably, the top of the positioning pin is hemispherical.

Preferably, the channels in the fixed die and the movable die are uniformly distributed and are parallel to each other.

Compared with the prior art, the utility model the beneficial effect who has is:

the production mould for casting the magnesium alloy anode through the iron core of the utility model bypasses the extrusion mode and uses the casting mode to produce the anticorrosive anode through the iron core; the connecting piece assembled subsequently can be cast in the anode together in the process of iron core anode casting production, and the irregular anode iron core can be cast in the anode; the casting gate is arranged at one end of the anode, and a finished product can be obtained after the gate is cut off after casting is finished, so that the appearance quality of the anode is not influenced; the molding casting plate is used for processing the casting mold, so that one mold can be used for producing more than one mold, and the production efficiency is improved; the mold is simple in structure and easy to process.

Drawings

FIG. 1 is a schematic view of an exploded structure of a production mold of the present invention;

fig. 2 is an exploded view of another perspective of the present invention.

In the figure: fixing a mold 1; a moving die 2; an iron core pressing block 3; an iron core positioning groove 4; a positioning pin 5; a magnesium alloy anode 6; a channel 7; and (6) positioning the holes 8.

Detailed Description

The invention will be further described with reference to specific examples.

However, the description of the present invention is merely a structural or functional description of an embodiment, and the scope of the present invention is not limited by the embodiments described herein.

For example, the embodiments may have various modifications and various forms, and it should be understood that the scope of the present invention includes equivalents capable of realizing the technical idea.

The channel 7 one end on the cover half 1 is equipped with iron core constant head tank 4, and the mould still includes iron core briquetting 3 that can press on iron core constant head tank 4, and iron core briquetting 3 is used for the fixed positioning iron core.

Be equipped with locating pin 5 on the cover half 1 of this embodiment, be equipped with on the movable mould 2 with the locating hole 8 of 5 looks adaptations of locating pin, 5 tops of locating pin are the hemisphere, are favorable to the compound die.

The movable mould 2 and the iron core pressing block 3 are subjected to anode casting after mould assembly, so that a plurality of magnesium alloy anodes 6 are obtained at one time, one mould is used for producing more magnesium alloy anodes, and the production efficiency is improved.

The utility model discloses replaced and used extruder production to run through the mode of the anticorrosive positive pole of iron core, carried out redesign to casting mould, defect such as not enough, cold shut appear watering in the mode of top feeding avoiding the product to appear, solved that AZ63 class magnesium alloy extrusion in-process extrusion temperature window is narrow, extrusion process is difficult to control, and compelled to use AZ31 class magnesium alloy product to carry out the embarrassing situation of replacing.
