Description

Novel die casting

Technical Field

The utility model relates to a die casting, concretely relates to novel die casting.

Background

The basic process of the high-pressure die-casting process is that molten metal is cast at low speed or high speed and filled into a cavity of a die, the die is provided with a movable cavity surface, and the die is pressed and forged along with the cooling process of the molten metal, so that the defects of shrinkage cavity and shrinkage porosity of a blank are eliminated, the internal structure of the blank reaches broken crystal grains in a forging state, and the comprehensive mechanical property of the blank can be obviously improved.

When molten metal is crystallized and solidified under higher pressure, the die is opened to enable the fixed die to be separated from the die casting, and the die casting is not ejected out of the movable die side of the die, the side face, close to the parting line position, of the die casting is in a free state, the free side face of the die casting can deform due to shrinkage of the bottom face, the die casting is in the free state at the parting line position, and a gap is formed between the die casting and the movable die side of the die due to the fact that the die casting deforms under the influence of shrinkage of the bottom face.

How to reduce and control the deformation of the thin-wall parts is a big difficulty, and particularly for the die casting with free deep-cavity opening structure, the difficulty is more obvious and difficult to solve.

The prior art has the defect that after the fixed die is separated, the side surface of the die casting close to the die parting line is influenced by the shrinkage of the bottom surface of the die casting, and a gap is formed between the die casting and the movable die side of the die.

SUMMERY OF THE UTILITY MODEL

In view of this, the utility model provides a novel die casting helps guaranteeing that the mould leaves at the cover half, the mould with can not produce the clearance between the movable mould side.

The technical scheme is as follows:

the utility model provides a novel die casting, its key lies in, including the die casting body, the die casting body includes die casting bottom plate and at least one die casting curb plate, die casting bottom plate level sets up, the die casting curb plate with the edge connection of die casting bottom plate, its characterized in that:

die casting curb plate with contained angle between the die casting bottom plate is greater than zero, the die casting curb plate is kept away from the edge of die casting bottom plate forms the spacing district of drawing of patterns, be equipped with arc transition face on the spacing district of drawing of patterns, arc transition face is followed the edge setting of die casting curb plate, arc transition face is located the die casting curb plate dorsad on the side of die casting bottom plate.

The effect of adopting above scheme: when the fixed die is separated, the die casting side plate is limited by the demolding limiting area, the side face, close to the die parting line, of the die casting is prevented from being affected by shrinkage of the bottom of the die casting, and a gap between the die casting side plate and the movable die side is avoided.

The arc radius of the arc transition surface is 0.5 mm.

The die casting side plate is provided with a plurality of reinforcing grooves, the reinforcing grooves are in one-to-one correspondence with the reinforcing openings, and the reinforcing openings are communicated with the corresponding reinforcing grooves.

The die casting side plates are arranged right opposite to each other, the die casting side plates are perpendicular to the die casting bottom plate, and the die casting side plates are located on the same side of the die casting bottom plate.

The reinforcing groove is in a semi-conical shape, and the reinforcing opening is matched with the cone bottom of the reinforcing groove.

The reinforced groove is in a half-prismatic table shape, and the reinforced opening is matched with the table bottom of the reinforced groove.

And a lightening hole is also penetrated through the die casting bottom plate.

The die casting bottom plate is further provided with at least one strip-shaped reinforcing beam, the strip-shaped reinforcing beam is arranged around the lightening hole, and the strip-shaped reinforcing beam and the die casting side plate are located on the same side.

Has the advantages that: the utility model discloses an it sets up the spacing district of drawing of patterns at the expansion end of mould, when the cover half breaks away from, utilizes the spacing district of drawing of patterns to carry on spacingly to the die casting curb plate, prevents that the side that the die casting is close to the parting line position from receiving the shrink influence of die casting bottom, has avoided and has produced the clearance between the movable mould side.
