Abstract
The utility model discloses a mould for a screw tap blank. The mold comprises an outer mould body. A handle is arranged on one side of the outer mould body. The outer mould body is provided with a sprue and a riser. The center of the outer mould body is provided with a cylindrical hollow cavity, an inner core is arranged in the cylindrical hollow cavity, and the center of the inner core is provided with a screw tap blank hole. By the aid of the inner core arranged in the cylindrical hollow cavity, iron scraps generated in the original blank turning process can be processed into finished products in the handle shrinkage process. On the basis of the original turning process and by the handle shrinkage tap overhead cold-drawing process, raw materials are saved, and production efficiency is improved. Compared with the conventional process, raw materials are saved by 25%, power consumption (energy consumption) is saved by 40%, and operators are saved by 50-60%.
Description
Technical field
The utility model relates to a kind of mould, particularly relates to a kind of mould of square-shank tap blank of contracting that is used to make.
Background technology
At present in the machined into; Adopt the mould of the existing square-shank tap blank that is used to contract; Produce the screw tap high material consumption; Production time is long, has had a strong impact on operating efficiency and economic benefit, and the cold drawn square-shank tap blank production technology that contracts of high-altitude single-point punching press that my company adopts has and saves material, enhances productivity and advantage such as economic benefit; And on average per hour produce 75 of screw tap blanks under the traditional handicraft, production efficiency is low.
The utility model content
The purpose of the utility model is to overcome the problems referred to above that prior art exists, and proposes a kind of screw tap blank mould.The utility model adopts in the cylindrical cavity inner core is set, and the waste iron filing that its original car base technology is produced becomes finished product in the handle technical process is contracted in employing; Upper cold pulling-down square-shank tap technology had both been practiced thrift raw material on original lathe technology basis, improved production efficiency again; Compare than traditional handicraft and to save material 25%; Save electricity (energy consumption) 40%; Saving personnel 50-60%.
The utility model adopts following technical scheme to realize:
A kind of screw tap blank mould comprises outer die body, and a side of said outer die body is provided with handle; Cast gate and rising head are arranged on the outer die body; The central authorities of outer die body are cylindrical cavity, it is characterized in that: in the said cylindrical cavity inner core is set, the middle position of said inner core is provided with the screw tap blank hole.
Said inner core is connected on the chassis of outer die body through welding or screw buckle.
Also be provided with spill port on the said outer die body.
The utility model compared with prior art, its advantage is:
1, the utility model adopts in the cylindrical cavity inner core is set, and the middle position of inner core is provided with the screw tap blank hole; Make the square-shank tap blank surface flatness that contracts high, do not have the defective of indentation; Blade, shank radial run-out are between the 0.10mm-0.08mm.
When 2, the utility model and forcing press are used, per hour can produce 1125 screw tap blanks through the cold drawn handle production technology that contracts of high-altitude single-point; Compare than traditional handicraft and to have improved production efficiency greatly.
3, the utility model adopts on the outer die body and also is provided with spill port, is used for circulation machine oil is played cooling and lubricated.

The specific embodiment
Embodiment 1:
A kind of screw tap blank mould comprises outer die body 1, and a side of said outer die body 1 is provided with handle 3; On the outer die body 1 cast gate and rising head are arranged; The central authorities of outer die body 1 are cylindrical cavity, and inner core 2 is set in the said cylindrical cavity, and the middle position of said inner core 2 is provided with the screw tap blank hole.
In the utility model, said inner core 2 is through on the chassis that is welded on outer die body 1; Also be provided with spill port 4 on the said outer die body 1.
The utility model when being used with forcing press, per hour can be produced 1125 screw tap blanks through the cold drawn handle production technology that contracts of high-altitude single-point in use; Compare than traditional handicraft and to have improved production efficiency greatly; Inner core 2 is set in the cylindrical cavity, and the middle position of inner core 2 is provided with the screw tap blank hole; Make the square-shank tap blank surface flatness that contracts high, do not have the defective of indentation; Blade, shank radial run-out are between the 0.10mm-0.08mm.
Embodiment 2:
A kind of screw tap blank mould comprises outer die body 1, and a side of said outer die body 1 is provided with handle 3; On the outer die body 1 cast gate and rising head are arranged; The central authorities of outer die body 1 are cylindrical cavity, and inner core 2 is set in the said cylindrical cavity, and the middle position of said inner core 2 is provided with the screw tap blank hole.
In the utility model, said inner core 2 is connected on the chassis of outer die body 1 through screw buckle; Also be provided with spill port 4 on the said outer die body 1.
The utility model because inner core 2 is connected on the chassis of outer die body through screw buckle, if inner core 2 damages, can be changed in use fast, makes things convenient for operation and maintenance.
