Abstract
The utility model belongs to mold design technical field more particularly to merotype gearshift swing rod mold.Including upper die and lower die, the die cavity of extrusion forming is useful in upper die and lower die, upper die and lower die are molded, and side sets die parting line along center line, and die parting line divides mould bases in the die cavity at its swing rod leg equipped with protrusion, and it is trapezium structure to divide mould bases.Using the compounded linear that polyteny combines as die parting line, angle, Dead Core Problems that the product is formed because of the drop of structure are avoided completely so during forging molding.
Description
Technical field
The utility model belongs to mold design technical field more particularly to merotype gearshift swing rod mold.
Background technology
In the prior art, gearshift swing rod is the more complicated special-shaped product of a construction, and not only facade construction is more complicated,
Its two non-coplanar leg is existing compared with mitre angle, does not form very big high low head in same level also, this causes
There is very big difficulty in the making of forging molding mold.Because there is very big horizontal drop, shaping in two legs of this product
What corresponding high low head will inevitably occur in the cavity of mould divides mould form, traditional to reduce point of drop by changing level angle
Mould method can not effectively avoid the defects of each position is there are the phenomenon that angle and dead angle, being easy to generate scarce material, because into
The not full of type makes it difficult to reach preferable form, has seriously affected the quality and performance of product.
Utility model content
The technical issues of the utility model solves is that existing shelves change swing rod mold and cannot effectively avoid each position and exist
The phenomenon that angle and dead angle, is easy to generate the defects of lacking material.
In order to solve the above-mentioned technical problem, the utility model provides following technical solution:Merotype gearshift swing rod mold, bag
Upper die and lower die are included, the die cavity of extrusion forming is useful in upper die and lower die, upper die and lower die are molded, and side is in
Line sets die parting line, and die parting line divides mould bases in the die cavity at its swing rod leg equipped with protrusion, and it is trapezium structure to divide mould bases.
Using above-mentioned technical proposal, in the utility model, the compounded linear combined using polyteny is passed through as die parting line
The angle and drop of reference product special-shaped part leg, upper die and lower die are molded, and side sets die parting line along center line, point
Loft is equipped with the mould bases that divides of protrusion in the die cavity at its swing rod leg, and die parting line is equipped with convex in the die cavity at its swing rod leg
That rises divides mould bases, and it is trapezium structure to divide mould bases.The product is avoided completely so during forging molding because the drop of structure
And angle, the Dead Core Problems formed.In the utility model, the product form after shaping can be made fuller；More curve parting line shapes
State effectively prevents the occurrence probability that special-shaped position lacks material；This die parting line delays drop by trapezoidal inclined-plane and acts on, and effectively slows down
Abrasion of the embryo material in forming process to mold；Product divides mould using the method for positive side flat cutting, can pass through entirety completely
The method of vertical sedimentation grinding tool is worn after secondary operation so that the processing of mold is more convenient, effectively save plus
Between man-hour.
Further, described to divide the major diameter of mould bases for 4mm~8mm, minor axis scope is 3mm~5mm.So can more preferably it help
Forging molding.
Further, described to divide mould bases for bow-shaped structural, the major diameter for dividing mould bases is 4mm~8mm.Bow-shaped structural can also lead to
It crosses inclined-plane and delays drop effect, effectively slow down abrasion of the embryo material in forming process to mold.
Description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
Fig. 1 is structure front view in embodiment 1 in merotype gearshift swing rod mold；
Fig. 2 is structure front view in embodiment 2 in merotype gearshift swing rod mold.
Specific embodiment
Embodiment 1
As shown in Figure 1：Merotype gearshift swing rod mold, including upper mold 1 and lower die 2, is useful in upper mold 1 and lower die 2
The die cavity 3 of extrusion forming, upper mold 1 and lower die 2 are molded, and side sets die parting line 4 along center line, and die parting line 4 is in its swing rod
Protrusion is equipped in die cavity at leg divides mould bases 5, and it is trapezium structure to divide mould bases 5.The major diameter of described point of mould bases 5 for 4mm~
8mm, minor axis scope are 3mm~5mm.
During work, the compounded linear combined using polyteny is as die parting line 4, by reference to product special-shaped part leg
Angle and drop, upper mold 1 and lower die 2 are molded, and side sets die parting line 4 along center line, and die parting line 4 is at its swing rod leg
Die cavity in be equipped with protrusion divide mould bases 5, divide mould bases 5 be trapezium structure.Avoid the production completely so during forging molding
Angle, the Dead Core Problems that product are formed because of the drop of structure.In the utility model, the product form after shaping can be made more full
It is full；More curve parting line forms effectively prevent the occurrence probability that special-shaped position lacks material；This die parting line delays drop by trapezoidal inclined-plane
Effect, effectively slows down abrasion of the embryo material in forming process to mold；Product divides mould using the method for positive side flat cutting, complete
Secondary operation after being worn entirely by the method for whole vertical sedimentation to grinding tool so that the processing of mold is more square
Just, process time is effectively saved.The major diameter of described point of mould bases 5 is 4mm~8mm, and minor axis scope is 3mm~5mm.It so can be with
It is more preferable to help forging molding.
Embodiment 2
As shown in Figure 2：Merotype gearshift swing rod mold, including upper mold 1 and lower die 2, is useful in upper mold 1 and lower die 2
The die cavity 3 of extrusion forming, upper mold 1 and lower die 2 are molded, and side sets die parting line 4 along center line, and die parting line 4 is in its swing rod
Protrusion is equipped in die cavity at leg divides mould bases 5, and it is bow-shaped structural to divide mould bases 5.Described point of mould bases 5 is bow-shaped structural, point
The major diameter of mould bases 5 is 4mm~8mm.
During work, the compounded linear combined using polyteny is as die parting line, by reference to product special-shaped part leg
Angle and drop, upper mold 1 and lower die 2 are molded, and side sets die parting line 4 along center line, and die parting line 4 is at its swing rod leg
Die cavity in be equipped with protrusion divide mould bases 5, divide mould bases 4 be bow-shaped structural.Avoid the production completely so during forging molding
Angle, the Dead Core Problems that product are formed because of the drop of structure.In the utility model, the product form after shaping can be made more full
It is full；More curve parting line forms effectively prevent the occurrence probability that special-shaped position lacks material；This die parting line 4 is delayed by bowed inclined-plane
Drop acts on, and effectively slows down abrasion of the embryo material in forming process to mold；Product divides mould using the method for positive side flat cutting,
Secondary operation after being worn completely by the method for whole vertical sedimentation to grinding tool so that the processing of mold is more square
Just, process time is effectively saved.Further, described to divide mould bases 5 for bow-shaped structural, the major diameter for dividing mould bases 5 is 4mm~8mm.
Bow-shaped structural can also delay drop effect by inclined-plane, effectively slow down abrasion of the embryo material in forming process to mold.
Above-described is only the preferred embodiment of the utility model, it is noted that for those skilled in the art
For, on the premise of the utility model structure is not departed from, several modifications and improvements can also be made, these should also be considered as this
