Description

A special mold for planet carrier casting

technical field

The utility model relates to a casting mold for a planet carrier.

Background technique

The planetary carrier is one of the main components of the planetary gear transmission. The planetary gear shaft or bearing is mounted on the planetary carrier. When the planetary wheel is used as a basic component, it is the part that bears the largest external force moment in the mechanism. Therefore, the planetary carrier during the casting process higher quality requirements.

In order to avoid shrinkage cavity and shrinkage porosity in the casting process, in the prior art, a feeding riser is installed on the mold, and the feeding riser is connected through an annular sprue, because the riser is large in size and the sprue is long , The riser, gate and runner of each blank require a large weight of molten iron, resulting in a waste of molten iron, a very low process yield, and an increase in the cost of each product. Here it is the weak point that existing technology exists.

Contents of the invention

The technical problem to be solved by the utility model is to provide a technical solution for a special mold for planetary frame casting in view of the deficiencies in the prior art. Improvement, the utility model is used to manufacture the planet carrier, which saves the consumption of casting liquid and reduces the processing cost.

This solution is realized through the following technical measures: a special mold for planetary carrier casting, including at least two mold bodies, two adjacent mold bodies are connected by a runner, and the runner is connected to one end of the vertical runner , the other end of the vertical sprue is connected to the sprue cup, and at least three insulation risers are arranged on the periphery of each mold body.

A further improvement of the utility model is that the runner is located on the center line of the two adjacent mold bodies, and the location of the runner further reduces the length of the runner and reduces the waste of molten iron .

A further improvement of the utility model is that the two ends of the runner are arranged opposite to the insulation risers on the two adjacent mold bodies, the molten iron first flows into the insulation riser through the runner, and the metal in the insulation riser The solidification time of the liquid is longer than that of the metal liquid in the cavity, so it has a good feeding effect,

The further improvement of the utility model is that one end of the vertical sprue is connected with the middle part of the horizontal sprue, so that the mold cavity and the thermal insulation riser can be evenly filled with casting liquid during the pouring process, which improves the production quality of the product , In addition, the length of the vertical runner is further reduced.

The further improvement of the utility model is that there are two mold bodies, and two casting products can be obtained for each casting, which greatly improves the production efficiency.

The further improvement of the present utility model is that the periphery of each mold body is provided with three insulation risers. If the number of insulation risers is more than three, too much molten iron will be wasted. If the number of insulation risers If it is less than three, a good feeding effect cannot be achieved. The three thermal insulation risers are evenly arranged, and during the cooling process, the three risers are evenly divided, and at the same time have a feeding effect, the feeding effect is good, and the castings produced are of high quality.

The further improvement of the utility model is that the diameter of the heat preservation riser is 40mm, and the height of the heat preservation riser is 70mm. Waste of casting solution.

The intentional effect of the utility model can be known from the description of the above scheme: it includes at least two mold bodies, and two adjacent mold bodies are connected by a runner, and the runner is connected to one end of the vertical runner. The other end of the vertical sprue is connected with the sprue cup, and at least three insulation risers are arranged on the periphery of each mold body. The utility model improves the shape of the riser, the shape of the sprue and the position of the sprue. The utility model is used to make the planetary frame, which can reduce the waste of molten iron, reduce the production cost, and more than double the process yield. Reached 69.34%.

It can be seen that, compared with the prior art, the utility model has substantive features and progress, and the beneficial effects of its implementation are also obvious.

detailed description

In order to clearly illustrate the technical features of the solution, the solution will be described below through a specific implementation mode combined with the accompanying drawings.

It can be seen from the accompanying drawings that a special mold for planet carrier casting includes at least two mold bodies, and two adjacent mold bodies are connected by a runner 9, and the runner 9 is connected to one end of the vertical runner 8, The other end of the vertical sprue 8 is connected to the sprue cup 7, and at least three insulation risers are arranged on the periphery of each mold body. The runner 9 is located on the connecting line between the centers of the two adjacent mold bodies. Both ends of the runner 9 are arranged opposite to the thermal insulation risers on the two adjacent mold bodies. One end of the vertical runner 8 is connected to the middle of the runner 9 .

Specifically, there are two mold bodies, and the periphery of each mold body is provided with three insulation risers, and the three insulation risers are evenly arranged, as shown in Figure 1, insulation riser 1, insulation riser Mouth 2 and insulation riser 3 are arranged on one mold body, insulation riser 4, insulation riser 5 and insulation riser 6 are arranged on another mold body, and the diameter of described insulation riser is 40mm, and the diameter of described insulation riser The height of the mouth is 70mm, the effect is the best, and the feeding effect of the thermal insulation riser is the best.

Although the specific implementation of the utility model has been described above in conjunction with the accompanying drawings, it does not limit the protection scope of the utility model. Those skilled in the art should understand that on the basis of the technical solution of the utility model, those skilled in the art do not need to Various modifications or deformations that can be made with creative efforts are still within the protection scope of the present utility model.
