Description
Technical Field
The utility model relates to a make mould of motor end cover.
Background
In the gravity casting of aluminum alloy, a bottom pouring type pouring system is generally adopted, molten metal enters a cavity through the system under the action of gravity, and is stably filled from bottom to top, so that the air exhaust and the slag skimming are facilitated, but the heat distribution of the cavity is unreasonable, and in most cases, a slag collecting bag is additionally arranged to replace a cross runner, so that the flowing route of the molten metal is too long, the heat loss is large, the structure is complex, and the manufacturing cost is high.
The pouring of end notes formula is just adopted to present preparation motor end cover, the tangential is intake and is cast, through last mould and lower module molding chamber promptly, go into the runner with the metal liquid pump, casting liquid casts around the die cavity periphery, the route length of metal liquid flow path, and motor end cover has a plurality of high feet, can be blockked by the high foot and reduce the velocity of flow when the metal liquid flows, it is longer to lead to the time that the die cavity was filled up to the metal liquid, the foundry goods produces easily and appears shrinkage cavity, the shrinkage porosity, the pinhole and presss from both sides casting defects such as sediment, cause the rejection rate to increase.
SUMMERY OF THE UTILITY MODEL
The utility model aims at overcoming above-mentioned defect, provide a mould of making motor end cover that reduces the die cavity time that the molten metal fills up.
The utility model adopts the following technical scheme:
a mould for manufacturing a motor end cover comprises an upper mould and a lower mould; the upper die comprises a positioning hole, an upper die and a cross gate block; the lower die comprises a positioning column, a lower die, an inner pouring gate block and a straight pouring gate; the upper die is placed on the lower die to form a closed space, and a cavity is formed between the upper die and the lower die; the inner pouring gate block is a trapezoidal block, an inner pouring gate is formed by the inclined waist, and the cavity is communicated with the inner pouring gate; the horizontal pouring gate block is an arc-shaped metal block, and a horizontal pouring gate is formed between the vertical pouring gates of the horizontal pouring gate block; the horizontal pouring gate is communicated with the straight pouring gate, and the horizontal pouring gate is communicated with the inner pouring gate.
Preferably, the ingate blocks are four blocks and are equidistantly distributed between the cavity 3 and the arc-shaped cross gate block 13.
Compared with the prior tangential water inlet, the utility model has the advantages that the utility model does not need to cast around the periphery of the cavity when flowing, and the route of the molten metal flow path is shortened; the flow velocity is prevented from being reduced due to the blockage of the high feet because the flow velocity does not pass through the plurality of high feet of the motor end cover; but directly get into the die cavity through four ingates after bypassing the horizontal runner, can fill the die cavity more fast, avoided the foundry goods to produce easily and appear casting defects such as shrinkage cavity, shrinkage porosity, pinhole and clamp sediment, the effectual rejection rate that has reduced.

Fig. 2 is a schematic view of the upper die of the present invention.
Fig. 3 is an overall horizontal sectional view of the present invention.
Detailed Description
In order to make the purpose and technical solution of the present invention clearer, the following description is made with reference to the accompanying drawings and embodiments to further explain the present invention:
the die for manufacturing the motor end cover as shown in fig. 1 to 3 comprises an upper die 1 and a lower die 2.
The upper die 1 comprises a positioning hole 11, an upper die 12 and a cross gate block 13.
The lower die 2 comprises a positioning column 21, a lower die 22, an inner pouring gate block 23 and a straight pouring gate 24.
Aligning the three positioning holes 11 and the corresponding positioning columns 21, placing the upper die 1 on the lower die 2 to form a closed space, and pumping metal liquid through a sprue 24; the upper mold 12 and the lower mold 22 form a cavity 3 therebetween.
The four-block inner pouring gate block 23 is a trapezoidal block, an inner pouring gate 5 is formed by an inclined waist and is equidistantly distributed between the cavity 3 and the arc-shaped cross pouring gate block 13; the cavity 3 is communicated with four ingates 5.
The horizontal runner block 13 is a circular arc-shaped metal block, and a horizontal runner 4 is formed between the vertical runners 24 of the horizontal runner block 13; the cross gate 4 communicates with the sprue 24 and the cross gate 4 communicates with the four ingates 5.
During casting, the upper die 1 is placed on the lower die 2 by aligning the positioning hole 11 and the positioning column 21, the molten metal is pumped into the sprue 24, and after the molten metal enters the cross runner 4 through the sprue 24, the molten metal enters the cavity through the four inner runners 5, compared with the current tangential water inlet, the utility model discloses during flowing, the casting is not required to be carried out around the periphery of the cavity, and the route of the molten metal flow path is shortened; the flow velocity is prevented from being reduced due to the blockage of the high feet because the flow velocity does not pass through the plurality of high feet of the motor end cover; but directly get into the die cavity 3 through four ingates 5 after bypassing the horizontal runner in, can fill the die cavity 3 more fast, avoided the foundry goods to produce easily and appear casting defects such as shrinkage cavity, shrinkage porosity, pinhole and clamp sediment, the effectual rejection rate that has reduced.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments still belong to the protection scope of the present invention.
