Abstract
The invention discloses a casting surface crack eliminating method. Aspects of the number of mold release and ejector rods of a mould, the injection speed and the like are analyzed so as to find out causes of generation of casting surface defects to eliminate cracks on the pressure casting surfaces.
Description
Technical field
The present invention relates to the solution of die casting blemish, especially be applicable to solve the way of die casting face crack.
Background technology
In die casting technique, because ejector beam skewness or quantity are inadequate, unbalance stress; The charging ram fixed head causes one side stressed large in when work deflection, and one side is stressed little, makes deformation of products and cracks; The foundry goods wall is too thin, distortion after shrinking, and cast(ing) surface can crack or local deformation, has affected like this outward appearance and the use of die casting.
Summary of the invention
For solving the defective of die casting face crack, the present invention has adopted respectively the kinds of processes method, thereby solves the defects of die casting of the type.
The technical solution adopted for the present invention to solve the technical problems is: set about from multipaths such as the releasing agent of mould, ejector beam quantity, injection speeds respectively, analyze the reason that casting surface defect produces, solve the die casting face crack.
The invention has the beneficial effects as follows, adopt method of the present invention, largely the upper crackle that solves the die casting surface.
The specific embodiment
The method of described solution cast(ing) surface crackle, specific as follows:
1, releasing agent keeps pure, and dope layer is an amount of, even, and die face dries up, and the time of spraying paint is unsuitable long.
2, increase ejector beam quantity, adjust its distributing position, make foundry goods eject stress equalization.
3, suitably reduce injection ratio pressure, reduce as far as possible injection speed.
4, adjust and reinstall ejector pin retaining plate.
It is emphasized that: above only is preferred embodiment of the present invention, be not that the present invention is done any pro forma restriction, every foundation technical spirit of the present invention all still belongs in the scope of technical solution of the present invention any simple modification, equivalent variations and modification that above embodiment does.
Claims (5)
1. solve the method for cast(ing) surface crackle, it is characterized in that the multipaths such as releasing agent, ejector beam quantity, injection speed from mould are set about, analyze the reason that casting surface defect produces, solve the die casting face crack.
2. the method for solution die casting face crack according to claim 1, its feature exists
Keep pure in releasing agent, dope layer is an amount of, even, and die face dries up, and the time of spraying paint is unsuitable long.
3. the method for solution die casting face crack according to claim 1 is characterized in that increasing ejector beam quantity, adjusts its distributing position, makes foundry goods eject stress equalization.
4. the method for solution die casting face crack according to claim 1 is characterized in that suitably reducing injection ratio pressure, reduces as far as possible injection speed.
5. the method for solution die casting face crack according to claim 1 is characterized in that adjusting and reinstalling ejector pin retaining plate.
