Abstract
A kind of casting lock handle; installation through-hole is set along columnar axial direction by the columnar axis body of one end of the handle in casting lock handle; installation through-hole runs through columnar axis body; and the first opening and the second opening are formed in the axis body both ends of handle front end; when corrosion-resistance treatment; first opening is located on positioning mold; corrosion resistant metal die casting formation die casting is flowed by the second opening at the top of axis body and forms corrosion resistant inner layer metal protective layer, and the corrosion resistant metal layer processing of die casting is carried out in the inside side walls of locating slot to realize.
Description
Technical field
The utility model is specifically related to casting lock handle technical field, and in particular to a kind of casting lock handle.
Background technique
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, so that the service life of metal lock handle is influenced, 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 being set to cooperation in press casting procedure between mold, therefore can not be corrosion-resistant to die casting is carried out 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.
Summary of the invention
In order to solve the deficiencies in the prior art, the utility model provides a kind of casting lock handle.
The technical solution that the present invention uses is: a kind of casting lock handle, including handle, and 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 and handle of the integral type are made 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, comprising the following steps:
(1) axis body of handle front end will be passed through using the lock handle of the axis body and handle with integral type of metal casting
First opening of bottom is located on positioning mold；
(2) outer layer for the lock handle being located on positioning mold is formed by corrosion resistant metal die casting corrosion resistant outer
Layer coat of metal flows into corrosion resistant metal die casting shape by the second opening at the top of axis body on the side wall of the inside of installation through-hole
Corrosion resistant inner layer metal protective layer is formed at die casting, that is, completes the outer layer of the lock handle and resistance on the inside of installation through-hole
Corrosion treatment.
The beneficial effects of the present invention are: the utility model provides a kind of casting lock handle, by holding in casting lock
Installation through-hole is arranged in the columnar axis body of one end of the handle of hand along columnar axial direction, and installation through-hole runs through columnar axis
Body, and when the axis body both ends of handle front end formation the first opening and the second opening, corrosion-resistance treatment, the first opening is located in
On position mould, corrosion resistant metal die casting formation die casting is flowed by the second opening at the top of axis body and forms corrosion resistant inner layer metal
Protective layer carries out the corrosion resistant metal layer processing of die casting to realize in the inside side walls of locating slot.
Detailed description of the invention

1- handle in figure, 2- metal layer, 3- axis body, 31- installation through-hole, 32- first are open, and 33- second is open.
Specific embodiment
Now in conjunction with Fig. 1, invention is further explained, a kind of casting lock handle, including handle 1, the handle
1 is made of metal, and the outer layer of the handle 1 is equipped with corrosion resistant metal layer 2, and one end of the handle 1 is columnar
Axis body 3 is an integral structure between the axis body 3 and handle 1.The axis body 3 and handle 1 of the integral type use die casting system
At.The columnar axis body 3 is provided with installation through-hole 31 along columnar axial direction, and the installation through-hole 31 is rectangular
Hole.The installation through-hole 31 runs through columnar axis body 3, and forms the first opening 32 and the in 3 both ends of axis body of 1 front end of handle
Two openings 33, also are provided with corrosion resistant metal layer 2 on the inner wall of the installation through-hole 31.
The corrosion resistant metal layer 2 is that aluminium or stainless steel material are suppressed.
A kind of method for anticorrosion-treating of casting lock handle, comprising the following steps:
(1) axis body of handle front end will be passed through using the lock handle of the axis body and handle with integral type of metal casting
First opening of bottom is located on positioning mold；
(2) outer layer for the lock handle being located on positioning mold is formed by corrosion resistant metal die casting corrosion resistant outer
Layer coat of metal flows into corrosion resistant metal die casting shape by the second opening at the top of axis body on the side wall of the inside of installation through-hole
Corrosion resistant inner layer metal protective layer is formed at die casting, that is, completes the outer layer of the lock handle and resistance on the inside of installation through-hole
Corrosion treatment.
The present invention is set along columnar axial direction by the columnar axis body of one end of the handle in casting lock handle
Installation through-hole is set, installation through-hole runs through columnar axis body, and forms the first opening and second in the axis body both ends of handle front end and open
Mouthful, when corrosion-resistance treatment, the first opening is located on positioning mold, is passed through the second opening at the top of axis body and is flowed into corrosion resistant metal
Die casting forms die casting and forms corrosion resistant inner layer metal protective layer, and die casting corrosion resistant is carried out in the inside side walls of locating slot to realize
The metal layer of erosion is handled.
The above is only a preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-mentioned implementation
Example, all technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
