Abstract
The invention discloses a kind of middle die sleeve forging piece molding die, it includes core roller and main mould, wherein, the both ends of the core roller are correspondingly arranged on construction section, the first cylindrical section is disposed between two construction sections, core roller oblique conical section, second cylindrical section and the 3rd cylindrical section, the diameter of first cylindrical section is less than the diameter of second cylindrical section, the diameter of 3rd cylindrical section is less than the diameter of first cylindrical section, the main mould is arranged at the side of the core roller, centre bore is provided with the center of the main mould, and the main mould includes the cylindrical section positioned at bottom and superposed main mould oblique conical section.Above-mentioned middle die sleeve forging piece molding die can process the forging closer to shape of product, and the chipping allowance of following process is small, save material, and processing cost is low, while mould is that forging process leaves certain calendering space, ensure that the quality and performance of product.
Description
Technical field
The invention belongs to mould for forging technology, more particularly, to a kind of middle die sleeve forging piece molding die.
Background technology
Middle die sleeve is to be used to transmit vulcanization mechanomotive force in rubber tyre mould and drive the part of mould, its
The processing mode of forging is mostly the forging that rectangular cross-section structure is first processed into mould for forging, then again will forging
Part cuts into close to after the shape of product design and finished, and this mode has that chipping allowance is big, wastes
The shortcomings that material, high processing costs.
The content of the invention
It is an object of the invention to provide a kind of middle die sleeve forging piece molding die, and it has, and chipping allowance is small, saves
The characteristics of material is low with processing cost, with existing above-mentioned during solution in the prior art middle die sleeve forging process
Problem.
To use following technical scheme up to this purpose, the present invention：
A kind of middle die sleeve forging piece molding die, it includes core roller and main mould, wherein, the both ends pair of the core roller
Construction section should be provided with, the first cylindrical section, core roller oblique conical section, second are disposed between two construction sections
Cylindrical section and the 3rd cylindrical section, the diameter of first cylindrical section are less than the diameter of second cylindrical section, institute
The diameter for stating the 3rd cylindrical section is less than the diameter of first cylindrical section, and the main mould is arranged at the core roller
Side, is provided with centre bore at the center of the main mould, and the main mould include positioned at bottom cylindrical section and
Superposed main mould oblique conical section.
Especially, the core roller oblique conical section is up-small and down-big, and the angle of its side wall and vertical direction is 14.5 °.
Especially, the R60 circular sliding slopes that second cylindrical section and the 3rd cylindrical section pass through indent.
Especially, the side wall of the main mould oblique conical section inwardly rolls oblique, and the angle of itself and vertical direction is 3 °.
Especially, two fins extended laterally are symmetrically arranged with the outer wall of the main mould.
Beneficial effects of the present invention are that the middle die sleeve forging piece molding die can be processed compared with prior art
Going out the forging closer to shape of product, the chipping allowance of following process is small, saves material, and processing cost is low,
Mould is that forging process leaves certain calendering space simultaneously, ensure that the quality and performance of product.
Brief description of the drawings
Fig. 1 is the structural representation for the middle die sleeve forging piece molding die that the specific embodiment of the invention 1 provides；
Fig. 2 is that the structure of the core roller for the middle die sleeve forging piece molding die that the specific embodiment of the invention 1 provides is shown
It is intended to.
Embodiment
Further illustrate technical scheme below in conjunction with the accompanying drawings and by embodiment.
Refer to shown in Fig. 1 and Fig. 2, in the present embodiment, a kind of middle die sleeve forging piece molding die includes core roller 1
With main mould 2, forging 3 is set, and the both ends of the core roller 1 are correspondingly arranged between the core roller 1 and main mould 2
Construction section 4, several different size of frustums of a cone are set side by side with the construction section 4.Two construction sections
The first cylindrical section 5, core roller oblique conical section 6, the second cylindrical section 7 and the 3rd cylindrical section 8 are disposed between 4,
The diameter of first cylindrical section 5 is less than the diameter of second cylindrical section 7, the 3rd cylindrical section 8
Diameter be less than first cylindrical section 5 diameter, the core roller oblique conical section 6 is up-small and down-big, and its side wall with
The angle of vertical direction is 14.5 °, the R60 that the cylindrical section 8 of the second cylindrical section 7 and the 3rd passes through indent
Circular sliding slopes.
The main mould 2 is arranged at the side of the core roller 1, and centre bore 9 is provided with the center of the main mould 2,
It is described and the main mould 2 includes the main mould cylindrical section 10 positioned at bottom and superposed main mould oblique conical section 11
The side wall of main mould oblique conical section 11 inwardly rolls oblique, and the angle of itself and vertical direction is 3 °, the main mould 2
Two fins extended laterally 12 are symmetrically arranged with outer wall.
Above example is to elaborate the general principle and characteristic of the present invention, and the present invention is not limited by above-mentioned example
System, without departing from the spirit and scope of the present invention, the present invention also have various change and change, these
Changes and modifications all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended power
Sharp claim and its equivalent thereof.
