Using punch-pin as upper die head, using cavity plate as lower die head, a kind of embodiment is only indicated.
In a specific embodiment, a kind of X shape ring molding die is present embodiments provided, the specific X type circle includes
Cope plate 1, lower template 2 and die head group.It should be noted that herein and in context, X shape ring is cross section in " X " type
Annular ring forms four upper, outside upper, interior lower and outer lower convexity protrusions respectively inwards, protrusion is in half that is, from the point of view of cross section
It is round.Specific shape, structure, the dimension reference prior art.The wherein generally annular rubber ring of X shape ring.
Wherein cope plate 1 and lower template 2 are respectively that two mounting bases are one and are mounted on if being assembled on machine
On pedestal, another installation is on the driving part.
Wherein die head group has the type chamber 7 for forming X shape ring, corresponding based on the shape of above-mentioned X shape ring, in type
In chamber 7, top is respectively formed interior upper direction and extends the salient point of protrusion and the salient point of outside upper direction extension protrusion, and shape is distinguished in lower part
At the interior lower salient point for extending protrusion and the outer lower salient point for extending protrusion.To direction in wherein, by the side of the circumferential axis of plesiotype chamber 7
To, and outward direction is the direction of the circumferential axis of remote release chamber 7.
Die head group is separated into using the annular cones face where 7 two of them of type the chamber mutually line far from salient point as die joint 8
Cavity plate 6 and punch-pin 5.Because angle of four salient points respectively between the line between central point is followed successively by an angle of 90 degrees, then dividing
8 coning angle of die face should be an angle of 90 degrees.
In one group of die head group, one in cavity plate 6 and punch-pin 5 is the upper die head for being mounted on cope plate 1, another is peace
Lower die head in lower template 2.Upper groove 54 that at this time can be downward in the downside forming open of upper die head, while can be upper
The upward lower groove 61 of the upside forming open of die head, wherein lower groove 61 and the composition of upper groove 54 form the type chamber 7 of X shape ring.
Wherein cavity plate 6 is matched with punch-pin 5, and in specific upper die head and lower die head, which is punch-pin 5, which is cavity plate
6, it is subject to point mould conical surface cone angle upward still downward, under concrete analysis is following,
If wherein cone angle is upward, then the line of upper salient point and outer lower salient point is defiber within being, i.e., where the line
Annular cones face be die joint so that interior lower part be above-mentioned lower groove 61, outer top be above-mentioned upper groove 54, wherein on
Lower half contouring, the profile of interior lower convexity and the lower half contouring of outer lower convexity of protrusion pass through the briquetting roller of lower groove 61
Exterior feature molding, and the upper half contouring of the upper half contouring of interior upper protrusion therein, the profile of outside upper protrusion and outer lower convexity is equal
It is formed by the profile of upper groove 54.Upper die head is cavity plate 6 at this time, and lower die head is punch-pin 5.
If cone angle is downward, then the line of upper salient point and interior lower salient point is defiber, i.e. ring where the line other than being
Shape circular conical surface is die joint 8, and lower groove 61 is the outer lower part of type chamber 7 at this time, and upper groove 54 is the internal upper part of type chamber 7.Wherein
The lower half contouring of the lower half contouring of outside upper protrusion, the profile of outer lower convexity and interior lower convexity pass through lower groove 61 at
Type is contoured, and the upper half of the upper half contouring of outside upper protrusion therein, the profile of interior upper protrusion and interior lower convexity is taken turns
It is wide to be formed by the profile of upper groove 54.Upper die head is punch-pin 5 at this time, and lower die head is cavity plate 6.
According to above-mentioned technical solution, when forming X shape ring, it is only necessary to by cope plate 1 and lower template 2, by upper mold
Head and lower die head are combined,, can be with wherein how to carry out filler can be used to form X shape ring so that type chamber 7 is closed
With reference to the prior art.And when needing on forming convax mould 5 and cavity plate 6 for combining the cavity plate 6 of shape forming cavity 7, because with two
It is mutually die joint 8 far from annular cones face where salient point line, so type chamber 7 is located at the part on punch-pin 5 and is located at cavity plate 6
On part, cross section groove width is in gradual shrinkage, so facilitating with an imitative type cutter head from outside to inside from notch to slot bottom
Processing, sufficiently to improve processing efficiency.In conclusion the X shape ring molding die can efficiently solve upper die head and lower die
The relatively difficult problem of forming recess 7 on head.
Further, it is contemplated that the actual temperature of mold when needing to control vulcanization of rubber press process is based on this, herein
It is preferred that being provided with a thermometer hole 11 on cope plate 1 and/or lower template 2, thermometer hole 11 is a blind hole, preferably to gather
Heat, more accurately to react the temperature inside cope plate 1 or lower template 2.Thermometer hole 11 is set such as on cope plate 1, it is a kind of
Relatively simple method is in the side of cope plate 1, and along parallel two sides plate face, i.e., the direction of plate face drills out a blind hole up and down,
Using as thermometer hole 11,11 diameter of thermometer hole be should not be too large, just the probe of thermal detector can be stretched in thermometer hole 11
Subject to.And depth be it is more more deep better, such as can be and stretch between two groups of mould groups, specifically can also be three groups of mould groups it
Between.
Further, it is contemplated that punch-pin 5 and the needs of cavity plate 6 precisely align, and can guarantee the molding of molding X shape ring
Quality.In order to be preferably oriented to, this is in lower template 2 and lower template 2 one and is fixedly installed with guide post 3, another
The guide sleeve 4 vertically matched with guide post 3 is installed, wherein guide post 3 is taper guide post, i.e., insertion end is path
End, is oriented to facilitating.Specifically, mounting hole 12 can be provided with, on cope plate 1 guide post 3, phase is fixedly mounted
It is corresponding, mounting hole 12 is equally set in lower template 2, guide sleeve 4 is fixedly mounted, naturally it is also possible to be to pacify guide post 3
