Description
Technical field
The present invention relates to ceramic injection forming mould applications, especially a kind of ceramic injection forming type core and contain the type
The ceramic insertion core mold of core.
Background technique
The structure of existing ceramic insertion core mold cores is generally as shown in Fig. 1, including mold core body and is connected to the type
The top of core ontology one end, the mold core body is generally pylindrical, and the length of the cylindrical male plug ontology is generally 8~
30mm, diameter are generally 0.08~0.2mm.During ceramic injection forming, product can smoothly be deviate from by jacking mode
Type core, since existing type core is cylinder, during demoulding, the frictional force of product and type core is big, and type core easily scratches production
Product inner hole, simultaneous type core is easy to wear, influences service life.
Summary of the invention
It is an object of the invention to provide a kind of demoulding in view of the deficiencies of the prior art mentioned above and be easy, avoid product
Inner hole scratch and the ceramic insertion core mold cores of reduced type core abrasion simultaneously.Meanwhile the present invention also provides include institute of the present invention
State the ceramic insertion core mold of type core.

Body and the top for being connected to described mold core body one end, the mold core body includes cylindrical section and conical section, the conical section packet
The smallest small end of diameter and the maximum big end of diameter are included, the cylindrical section is connect with the small end of the conical section.
Ceramic insertion core mold cores of the invention, mold core body therein include cylindrical section and conical section, and circle therein
The small end of cone section is connect with the cylindrical section, is formed diameter and is become larger the mold core body structure with certain taper, this knot
For the mold core body of structure compared with the identical cylindrical male plug of uniform diameter in the prior art, frictional force during demoulding is obvious
Reduce, effectively reduce the abrasion of type core, while solving the problems, such as inner hole scuffing during product stripping difficulty and product stripping.
As the preferred embodiment of ceramic insertion core mold cores of the present invention, in the mold core body, circular cone segment length
Degree accounts for the 50~100% of the mold core body total length.In ceramic insertion core mold cores of the present invention, in the mold core body
The length of circular cone at least accounts for the 50% of mold core body total length, i.e., the length of the described conical section is greater than or equal to the journey of cylindrical section
Degree, the restriction of circular cone segment length ensure that the taper of mold core body entirety, effective guarantee product frictional force during demoulding
Reduce.When the circular cone segment length accounts for the 100% of the mold core body total length, the mold core body is all by conical section shape
At that is, described mold core body generally conical structure can more reduce the friction in knockout course to a greater extent in this way
Power, it is better to solve the problems, such as that inner hole scratches when the difficult abrasion of type core, product stripping and product stripping.
As the preferred embodiment of ceramic insertion core mold cores of the present invention, in the mold core body, the cylinder
Segment length accounts for the 0~50% of the mold core body total length.
As the preferred embodiment of ceramic insertion core mold cores of the present invention, in the mold core body, the cylinder
The diameter of section is 0.05~0.3mm.
As the preferred embodiment of ceramic insertion core mold cores of the present invention, in the mold core body, the cylinder
The diameter of section is 0.08~0.2mm.
As the preferred embodiment of ceramic insertion core mold cores of the present invention, in the mold core body, the cylinder
The diameter of section is identical as the end diameter of the conical section.
As the preferred embodiment of ceramic insertion core mold cores of the present invention, in the mold core body, the circular cone
The outside diameter of section is 1.01~1.5 times of the cylindrical section diameter.The outside diameter of the conical section is that the cylindrical section is straight
1.01~1.5 times of diameter enable to the conical section to have suitable taper, and then ensure that mold core body integrally has properly
Taper, to preferably overcome the problems, such as that conical type core exists in the prior art.
As the preferred embodiment of ceramic insertion core mold cores of the present invention, the total length of the mold core body is 5
~40mm.
