Description
Technical Field
The utility model belongs to the technical field of die-casting, concretely relates to unilateral of production motor casing advances to water mould.
Background
The motor shell is used as a key part of an automobile motor module, and the excellent air tightness is a necessary condition for ensuring the efficient work of the motor. In operational environment, motor casing is often in the high temperature, needs water-cooling system to satisfy motor system's heat dissipation requirement, and although the hydrologic cycle radiating effect is obvious, water circulation system structure is complicated, has the water seepage risk, so requires motor casing to have higher gas tightness.
The motor shell is mainly made of cast iron and aluminum alloy, and the manufacturing process mainly adopts the traditional processes of pressure casting, low-pressure casting and the like. In the conventional die casting process of the motor shell, a semi-circular type pouring mode is adopted to fill a die cavity, air in the die cavity cannot be discharged in time, residual gas easily enters a casting, a large number of air holes appear in the casting in the subsequent process, the performance of the casting is obviously reduced, the requirement on air tightness does not reach the standard, and the yield is low.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem to prior art's current situation, and provide a unilateral of production motor casing advances to water the mould.
The utility model provides a technical scheme that above-mentioned technical problem adopted does: the utility model provides a mould is watered in unilateral of production motor casing includes: a mold main body and an inlet gate provided at a side of an upper end of the mold main body and provided at a position of a circumference of 1/4 of the upper end of the mold main body, the inlet gate including: a gate opening;
the main pouring gate is arranged at one end of the pouring gate opening, a plurality of shunting branch passages are arranged on the main pouring gate, and each shunting branch passage is connected with the die main body.
In the above single-edge pouring die for producing the motor shell, the two sides of the die body are provided with the exhaust grooves.
In the above single-edge pouring mold for producing the motor shell, a lower runner is arranged on one side of the mold main body, and the lower runner is connected with the exhaust groove.
In the above single-edge pouring die for producing the motor shell, the end part of the lower runner is provided with the wide flaring, and the wide flaring is connected with the die main body.
Compared with the prior art, the utility model has the advantages of: the speed and the pressure of the alloy liquid entering the cavity are improved by adopting the gate with a single-side gate, the impact force on bubbles in the alloy liquid is increased, the wide flaring is arranged at the lower end of the die, the alloy liquid is stably filled, most of air in the die cavity can be discharged through the exhaust groove, part of gas dissolved in the alloy liquid can gradually escape under the action of pressure, the air holes of a die-casting part are few, and the air tightness of the product is high.

Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1 and 2, the utility model relates to a single-side casting mold for producing motor shell, which comprises: a mold main body 1 and an inlet gate 2, wherein the inlet gate 2 is arranged at one side of the upper end of the mold main body 1, and the inlet gate 2 is arranged at the circumference of the upper end 1/4 of the mold main body 1, and the inlet gate 2 comprises: a gate opening 21; and the main pouring channel 22 is arranged at one end of the pouring channel opening 21, a plurality of branch flow channels 23 are arranged on the main pouring channel 22, and each branch flow channel 23 is connected with the die main body 1.
During casting, the casting liquid enters the main pouring gate 22 from the pouring gate 21 and enters the cavity through the branch passage 23. The die main body 1 is provided with the inlet gate 2 which only occupies the 1/4 circumference of the die main body 1, the single-side inlet pouring mode is adopted, the speed and the pressure of the alloy liquid entering the cavity are improved, the impact force on bubbles in the alloy liquid is increased, most of air in the cavity is removed, and part of gas dissolved in the alloy liquid gradually escapes under the action of pressure, so that the die-casting part has few air holes, and the product has high air tightness.
The two sides of the mould main body 1 are both provided with exhaust grooves 3.
Exhaust grooves 3 are formed in two sides of the die body 1, redundant gas in the die body 1 can be exhausted into the exhaust grooves 3, and bubbles outside a product are reduced.
One side of the die main body 1 is provided with a lower runner 4, and the lower runner 4 is connected with the exhaust groove 3.
Set up down runner 4 on the mould main part 1, casting liquid in the runner 4 can follow mould main part 1 lower extreme upflow, casting liquid in the sprue 22 can follow mould main part 1 upper end downflow simultaneously, flow to mould main part 1 inside simultaneously from two directions like this, can make casting liquid's flow distance shorter, it is too much to avoid casting liquid temperature reduction during flowing, prevent that casting liquid from solidifying in mould main part 1 during flowing, improve product quality, reduce the defective rate of product.
The end part of the lower runner 4 is provided with a wide flaring 5, and the wide flaring 5 is connected with the die main body 1.
4 tip of runner down sets up wide body flaring 5, and the width of wide body flaring 5 is greater than the width of 4 upper ends of runner down, and the pressure of casting liquid after getting into wide body flaring 5 diminishes, can make the velocity of flow of casting liquid when getting into mould main part 1 diminish like this, and the flow of casting liquid can slow flow into to mould main part 1 in, prevents that the casting liquid from being drawn into gas in mould main part 1, avoids the inside bubble that forms of product.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein will be apparent to those skilled in the art without departing from the scope and spirit of the invention as defined in the accompanying claims.
