Description

Sprue runner of one-mold two-cavity large-shell die-casting mold

Technical Field

The utility model relates to a big casing die casting die, especially a big casing die casting die runner in two chambeies of a mould.

Background

A large housing part of the company is shown in FIG. 1, and has a maximum dimension of 158.1X 55.5X 63mm and a minimum wall thickness of 1.5 mm. In the prior art, under a conventional pouring gate, the filling of a part is continuous and uninterrupted, the filling performance is feasible, but as is obvious from the attached

drawings

2 and 3 for continuous filling, the flow of molten metal is non-uniform in the production process due to the influence of a pillow position at the position A for casting a large shell, which leads to that one side of the part is filled better than the other side, and the position A on one side of the pillow position cannot be balanced with the other side no matter the material temperature or the zinc material is, so that the position is easy to generate die casting defects (bubbles, looseness, patterns and the like), and the design flow channel of a die needs to be perfected.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a big casing die casting die runner in two chambeies of a mould. The utility model has the characteristics of metal liquid flowing ratio is more balanced, and its die-casting defect is less, fills the performance good, and the qualification rate is high, can satisfy the production operation requirement.

The technical scheme of the utility model: a sprue runner of a one-mold two-cavity large-shell die-casting mold comprises a die-casting mold, wherein a sprue is arranged on the die-casting mold, a main runner is connected onto the sprue, and an auxiliary runner is arranged on a position A, used for casting one side of a pillow position of a large shell, on the die-casting mold.

In the sprue runner of the one-mold two-cavity large-shell die-casting mold, the pillow position of the large-shell die-casting mold is located between the main runner and the auxiliary runner.

In the sprue runner of the one-die two-cavity large-casing die-casting die, the auxiliary runner is connected with the sprue.

Compared with the prior art, the utility model discloses following beneficial effect has:

1. the method is characterized in that a die flow analysis is carried out on the existing die-casting die, and the analysis screenshot is as shown in fig. 2 and 3, wherein the influence of a pillow position at a position A for casting a large shell causes that one side of a part is better filled than the other side of the part, so that the flow of molten metal is non-uniform in the production process, and no matter the material temperature or the quantity of zinc materials at the position A at one side of the pillow position cannot be balanced with the other side, so that die-casting defects (bubbles, looseness, patterns and the like) are easily generated at the position;

2. for the mold flow analysis, a pouring gate of the die-casting mold is perfected, an auxiliary flow channel is added at the position A, the filling performance at the position A on the pillow position side is improved, and specifically, the auxiliary flow channel is arranged at the position A on the pillow position side of the die-casting mold for casting the large shell, as shown in fig. 4;

3. after the completion, the die flow analysis is carried out on the die again, the analysis screenshots are shown in fig. 5 and fig. 6 continuously, and through analysis, the molten metal flow is relatively balanced, the die casting defects are fewer, and the filling performance is good. The mould is designed and manufactured according to the structure, and can meet the production and use requirements.

4. Adopt prior art or the utility model discloses a big casing part finished product qualification rate: the percent of pass of the prior art is 43.23-45.62%; the percent of pass of the utility model is 99.23-99.75%, which greatly reduces the production cost and improves the production efficiency.

To sum up, the utility model discloses it is more balanced to have the metal liquid flow, and its die-casting defect is less, fills the performance well, and the qualification rate is high, can satisfy the beneficial effect of production operation requirement.

Detailed Description

The following description is made with reference to the accompanying drawings and examples, but not to be construed as limiting the invention.

Examples are given. A sprue runner of a one-die two-cavity large-shell die-casting die is shown in figures 1-6 and comprises a die-casting die 1, wherein a sprue 2 is arranged on the die-casting die 1, a main runner 3 is connected onto the sprue 2, and an auxiliary runner 4 is arranged on a position A6 on the side, where a pillow position 7 of a large shell 5 is cast, of the die-casting die 1.

The die-casting die 1 is used for casting a large shell 5, and a pillow position 7 is positioned between the main runner 3 and the auxiliary runner 4.

The auxiliary runner 4 is connected to the gate 2.

The utility model discloses a be used for casting 5 big casings on die casting die 1 and be equipped with auxiliary flow channel 4 on position A6 on pillow position 7 one side, perfect die casting die 1's runner 2, position A6 increases auxiliary flow channel 4, improves the filling performance of pillow position 7 one side position A6 department, realizes that pillow position 7 both sides metal liquid flow is more balanced; under the effect that is connected with sprue 3 and auxiliary runner 4 and runner 2 on runner 2, pour simultaneously big casing 5 through sprue 3 and auxiliary runner 4 on runner 2, so the utility model discloses the die-casting defect is less, and it is good to fill the performance, has avoided "among the prior art mould because pillow position 7 leads to the flow imbalance of both sides molten metal to easily produce the die-casting defect", the qualification rate is also improved to 99.23-99.75% by original 43.23-45.62%, greatly reduced manufacturing cost, improvement production efficiency can satisfy the production operation requirement.
