Abstract

The utility model provides a wiper linking arm die casting die who preapres for an unfavorable turn of events shape, includes cope match -plate pattern and lower bolster, the cope match -plate pattern is equipped with the shaping die surface, be equipped with down the shaping die surface on the lower bolster, it is formed with two wiper linking arm die cavitys with lower shaping die surface compound die to go up the shaping die surface, the protruding bar molding arch that is equipped with in the wiper linking arm die cavity on the lower shaping die surface, the bellied minor face of bar molding side is equipped with and keeps colluding. 1, the adoption keeps colluding holds the wiper linking arm for the wiper linking arm is unlikely to to warp. 2, the bellied setting of bar molding can save material, prevents the production of draw simultaneously. 3, have two wiper linking arm die cavitys, the process velocity is fast.

Description

A kind of distortion-free wiper linking arm die casting

Technical field

The utility model relates to a kind of aluminium die casting, particularly a kind of aluminium die casting of wiper linking arm.

Background technology

Present wiper linking arm is in order to when die casting, and owing to being bar shaped, the quiet mould enclasping force great disparity of dynamic model in shaping process, easily produce distortion, serious cracks, and this have impact on the quality of wiper linking arm greatly.

Summary of the invention

Hold yielding deficiency to overcome existing wiper linking arm, the utility model provides a kind of distortion-free wiper linking arm die casting.

The technical scheme in the invention for solving the technical problem is: a kind of distortion-free wiper linking arm die casting, comprise cope match-plate pattern and lower bolster, described cope match-plate pattern is provided with molding plane, described lower bolster is provided with compacted under die face, described upper molding plane and compacted under die face matched moulds are formed with two wiper linking arm die cavitys, described compacted under die face is convexly equipped with bar shaped moulding in wiper linking arm die cavity protruding, the short brink of described bar shaped moulding projection is provided with and keeps hooking.

Further, the height that described maintenance hooks is 1 ~ 2 millimeter.

The utility model in use bar shaped moulding projection, when aluminium liquid cooling but, can hold wiper linking arm, makes wiper linking arm be unlikely to distortion.

The beneficial effects of the utility model are: 1, adopt to keep hooking and hold wiper linking arm, make wiper linking arm be unlikely to distortion.2, the setting of bar shaped moulding projection can save material, prevents the generation of draw simultaneously.3, have two wiper linking arm die cavitys, process velocity is fast.

Fig. 2 is cross-sectional view of the present utility model.

Fig. 3 is that the utility model lower bolster produces schematic diagram.

Fig. 4 is Fig. 3 is A place enlarged diagram.

Detailed description of the invention

Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.

By reference to the accompanying drawings 1 to 3, a kind of distortion-free wiper linking arm die casting, comprise cope match-plate pattern 1 and lower bolster 2, described cope match-plate pattern 1 is provided with molding plane, described lower bolster 2 is provided with compacted under die face 3, described upper molding plane and compacted under die face matched moulds are formed with two wiper linking arm die cavitys 4, and described compacted under die face is convexly equipped with bar shaped moulding projection 5 in wiper linking arm die cavity, and the short brink of described bar shaped moulding projection is provided with and keeps hook 6.

Further, the height of described maintenance hook 6 is 1 ~ 2 millimeter.Be convenient to the demoulding like this.

The beneficial effects of the utility model are: 1, adopt to keep hooking and hold wiper linking arm 7, make wiper linking arm be unlikely to distortion.2, the setting of bar shaped moulding projection can save material, prevents the generation of draw simultaneously.3, have two wiper linking arm die cavitys, process velocity is fast.
