Background technology
General metal lock handle generally uses the metal castings such as iron, but the lock handle of these existing metal castings
It is easy to occur phenomena such as rust corrosion occurs in the long-term use, to influence the service life of metal lock handle, because
In this existing production process, often in metal lock handle outer layer one layer of corrosion resistant metal layer of die casting again, reach anti-life
The function of rust corrosion, but since the handle of metal lock handle is generally there are a slot used for positioning, and in locating slot by
It carries out in press casting procedure being set to cooperation between mold, therefore can not be corrosion-resistant to carrying out die casting in the inside side walls of locating slot
Metal layer processing, be easy to cause on the inside of locating slot and generate corrosion phenomenon and occur.
Invention content
It is of the invention to provide a kind of casting lock handle and its corrosion-resistance treatment side in order to solve the deficiencies in the prior art
Method.
The technical solution that the present invention uses is：A kind of casting lock handle, including handle, the handle is using gold
Category is made, and the outer layer of the handle is equipped with corrosion resistant metal layer, and one end of the handle is columnar axis body, described
Columnar axis body is provided with installation through-hole along columnar axial direction, and the installation through-hole runs through columnar axis body, and in
The axis body both ends of handle front end form the first opening and the second opening, also are provided on the inner wall of the installation through-hole corrosion resistant
Metal layer.
The installation through-hole is square hole.
It is an integral structure between the axis body and handle.
The axis body of the integral type is made with handle of die casting.
The corrosion resistant metal layer is that aluminium or stainless steel material are suppressed
A kind of method for anticorrosion-treating of casting lock handle, includes the following steps：
（1）The axis body bottom that will handle front end be passed through using the lock handle of the axis body and handle with integral type of metal casting
First opening be located on positioning mold；
（2）Corrosion resistant outer layer gold is formed by corrosion resistant metal die casting to the outer layer for the lock handle being located on positioning mold
Belong to protective layer, flowing into corrosion resistant metal die casting by the second opening at the top of axis body on the side wall of the inside of installation through-hole forms pressure
Cast completes the outer layer of the lock handle and corrosion-resistant on the inside of installation through-hole at corrosion resistant inner layer metal protective layer
Processing.
The beneficial effects of the invention are as follows：The present invention provides a kind of casting lock handle and its method for anticorrosion-treating, lead to
It crosses the columnar axis body in one end of the handle of casting lock handle and installation through-hole is set along columnar axial direction, installation is logical
Columnar axis body is run through in hole, and when the first opening of the axis body both ends of handle front end formation and the second opening, corrosion-resistance treatment, the
One opening is located on positioning mold, is formed by the second opening inflow corrosion resistant metal die casting formation die casting at the top of axis body resistance to
The inner layer metal protective layer of corrosion carries out the corrosion resistant metal layer processing of die casting in the inside side walls to realize locating slot.
