Abstract
The utility model is related to a kind of processing unit (plant)s of Shockproof rubber circle, belong to machinery manufacturing technology field.Its technical characteristics is that it is made of upper mold and lower die, and the annular tubular hollow cavity that one end cross sectional shape is trapezium structure is equipped between upper mold and lower die connection；Stress possibility of cracks when the parting of upper mold and lower die molding seam can be pressed on the upper bottom of trapezoid cross section and the intersection point of waist to avoid yielding rubber circle；Upper mold is formed by angle α, α with lower die parting1Between 90 ° 180 °, wedge angle can be formed to avoid mold, prevent damage of colliding with during mold use, raising die life.
Description
Technical field
The utility model is related to a kind of processing unit (plant) of rubber ring, the processing of specifically a kind of yielding rubber circle fills
It sets, belongs to machinery manufacturing technology field.
Background technology
In industrial processes, when using two molds, to produce an a kind of end section be trapezoidal yielding rubber circle, pass
The machining device design of system is：The die joint of its upper die and lower die is located at trapezoidal bottom on the intersection point of waist, this structure design produces
The molding of yielding rubber circle be sewn on during press fitting by prolonged extruding force, be easy cracking.
When the die joint of upper die and lower die to be moved to the intersection point at trapezoidal upper bottom and waist, the rubber ring of traditional design is processed
Device can form wedge angle in lower die position, which easy tos produce in use knocks damage, weighs wounded, shortens making for mold
Use the service life.
Utility model content
In order to overcome, existing to produce an a kind of end section using two molds be trapezoidal damping to the purpose of this utility model
The processing unit (plant) of rubber ring, when the die joint of the processing unit (plant) is located at trapezoidal bottom and the intersection point of waist, molding seam stress is very big,
Cracking is easy when press fitting, when die joint is moved to the intersection point positioned at trapezoidal upper bottom and waist, lower die position forms wedge angle and is easy to knock
The bad phenomenon of clashing and breaking, to provide a kind of new technical solution.
In order to achieve the above objectives, the utility model can be achieved through the following technical solutions：
A kind of processing unit (plant) of yielding rubber circle, it is made of upper mold and lower die, is set between upper mold and lower die connection
One end cross sectional shape is the annular tubular hollow cavity of trapezium structure.
Upper mold is T-shaped structure, and lower die is U-shaped structure, and the upper bottom that parting is located at trapezoid cross section is stitched in the molding of upper mold and lower die
With on the intersection point of waist.
Upper mold is formed by angle α, the α of molding seam and molding seam with lower die parting1Between 90 ° -180 °.
The utility model has an advantageous effect in that compared with prior art：Simple in structure, manufacturing cost is cheap, uses the longevity
Life length, it is to avoid and subtract at trapezoidal end faces that molding seam is moved to yielding rubber circle cross sectional shape by upper die and lower die in design
Shake the possibility to crack when rubber ring stress.Upper mold is formed by angle α, α with lower die parting1Respectively greater than 90 ° can be to avoid mould
Tool forms wedge angle, prevents damage of colliding with during mold use, raising die life.
Description of the drawings
Fig. 1 is a kind of example structure schematic diagram of the utility model.
Specific implementation mode
The utility model is described in further detail with specific embodiment in conjunction with attached drawing：
A kind of processing unit (plant) of yielding rubber circle, it is made of upper mold 2 and lower die 3, and 2 section of upper mold is T-shaped structure, under
3 section of mould is U-shaped structure, and upper mold 2 is formed by the angle α of molding seam with the parting molding seam of 3 upper end of lower die and trapezoidal upper bottom
It is 120 degree；The parting molding seam of upper mold 2 and 3 lower end of lower die is formed by the angle α for molding seam with trapezoidal waist1It is 150 degree.
The size of yielding rubber circle is by the annular tubular hollow cavity that is formed between upper mold 2 and lower die 3 according to different requirements,
Its shape of the size of body 1 is changeable, and one end cross sectional shape is trapezium structure, and the other end can be plane or section is ladder
Shape, circular arc.
Parting molding seam is moved on the above and below of yielding rubber circle, when molding seam press fitting does not stress, can be to avoid subtracting
Shake rubber ring cracking.
The yielding rubber that the annular tubular hollow cavity 1 formed between upper mold 2 in the utility model and lower die 3 is suppressed
Enclose the realization method of structural design of fittings：Mold design is two die sinkings, upper mold 2 and 3 parting of lower die molding seam be formed by angle α,
α1Respectively greater than 90 °, wedge angle can be formed to avoid mold, prevent damage of colliding with during mold use, raising die life.
