Abstract
The present invention relates to technical field of mold, especially a kind of compression pin head part mould core rod die sleeve, compress pin for clamping and comprise core rod group, described core rod group breaks formula for two, coordinated by two symmetrically arranged core rods and form, forming one in the cooperation place of core rod group for placing the counter sink compressing pin, described core rod group outer wall being set with one for clamping the die sleeve of core rod group.Compression pin head part mould core rod die sleeve of the present invention breaks formula core rod group by employing is two, compression pin is clipped in wherein, because core rod group is trapezoid block shape, the effect clamping core rod group is played by being connected with die sleeve profile, also can conveniently exit core rod group simultaneously, thus compression pin just can conveniently take out, thus structure of the present invention is simple, can share in the different operations that compression pin head part is shaping, do not need at other clamping molds of exploitation, decrease cost, the facility simultaneously compressing pin taking-up too increases efficiency.
Description
Technical field
The present invention relates to technical field of mold, especially a kind of compression pin head part mould core rod die sleeve.
Background technology
In automobile industry, automobile brake mouth commonly uses suspension rod and also namely compresses pin, traditional needs jumping-up for the processing compressing pin head part, the operations such as blanking, different operation completes the difference processing to compressing pin head part, because compression pin is component of rod category, so need can process compressing after pin is fixedly clamped, to ensure the quality of product, and in tradition processing, the mould compressing pin head part molding clamp is existed to the problem of clamping effect difference, simultaneously, process in different operation when compression pin and also can need different clamping molds, thus the problem on cost is brought, and also there is manual trouble in the blanking compressing pin, efficiency is difficult to promote.
Summary of the invention
The technical problem to be solved in the present invention is: poor in order to solve compression pin clamping effect in prior art, compress pin finished product and take off time-consuming technical problem, there is provided a kind of and compress pin head part mould core rod die sleeve, can toss about in bed to use in each operation, different fixtures need not be changed for different operation.
The technical solution adopted for the present invention to solve the technical problems is: a kind of compression pin head part mould core rod die sleeve, pin is compressed for clamping, comprise core rod group, described core rod group breaks formula for two, coordinated by two symmetrically arranged core rods and form, forming one in the cooperation place of core rod group for placing the counter sink compressing pin, described core rod group outer wall being set with one for clamping the die sleeve of core rod group.
In order to can core rod group is fixing and core rod group take out better, described die sleeve is cuboid, the front-back top of die sleeve has the breach running through described front-back, notch is had in the middle part of described die sleeve, described notch cross section is trapezoidal, described core rod group is trapezoidal shape, and core rod group and the notch of die sleeve are that profile is connected.
In order to mating mold processing, the large end surfaces two edges of described core rod group are symmetrically arranged with jack, and the angle of inclination of described jack is identical with the gradient on two inclined-planes of core rod group with direction.The push rod compressed on pin head part mould patrix is inserted in this jack, and die sleeve is withstood by the depression bar of patrix, and the process that die sleeve declines and core rod group rise.
As preferably, the gradient on the angle of inclination of described jack and two inclined-planes of core rod group is 80 °.
The invention has the beneficial effects as follows, mould of the present invention compresses the shaping core retainer plate of pin head part and breaks formula core rod group by employing is two, compression pin is clipped in wherein, because core rod group is trapezoid block shape, the effect clamping core rod group is played by being connected with die sleeve profile, also can conveniently exit core rod group simultaneously, thus compression pin just can conveniently take out, thus structure of the present invention is simple, can share in the different operations that compression pin head part is shaping, do not need, at other clamping molds of exploitation, to decrease cost, the facility simultaneously compressing pin taking-up too increases efficiency.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
Embodiment
As shown in figures 1-4, this mould compresses the shaping core retainer plate of pin head part, pin 1 is compressed for clamping, comprise core rod group 2, core rod group 2 breaks formula for two, coordinated by two symmetrically arranged core rods 3 and form, one is formed for placing the counter sink 4 compressing pin 1 in the cooperation place of core rod group 2, core rod group 2 outer wall is set with one for clamping the die sleeve 5 of core rod group 2, die sleeve 5 is cuboid, the front-back top of die sleeve 5 has the breach 52 running through front-back, notch 51 is had in the middle part of die sleeve 5, notch 51 cross section is trapezoidal, core rod group 2 is trapezoidal shape, the notch 51 of core rod group 2 and die sleeve 5 is connected for profile, the large end surfaces two edges of core rod group 2 are symmetrically arranged with jack 21, the angle of inclination of jack 21 is identical with the gradient on two inclined-planes of core rod group 2 with direction, take out from die sleeve in order to the core rod group being is easier and is convenient to coordinate and compress pin molding procedure, in the design, the gradient on the angle of inclination of jack 21 and two inclined-planes of core rod group 2 is 80 °.
When compressing pin 1 jumping-up, when the present invention is placed in counterdie, be equipped with in counter sink 4 and compress pin 1, the downward punching press of patrix, compression pin 1 is headed into jumping-up in counterdie jumping-up chamber, when when compressing pin 1 and ejecting station, during the downward punching press of patrix, compress pin 1 due to patrix act on move down in core rod group 2 a bit of, when when flattening station, the present invention is withstood in the downward punching press of patrix, complete the flattening work compressing pin 1 head, drop when namely compressing pin 1 finished product at blanking station, during the now downward punching press of patrix, the blanking bar of patrix is inserted in two jacks 21 of core rod group 2, die sleeve 5 is withstood by push rod, owing to there is gradient, core rod 3 then in core rod group 2 is separated, at this moment shaping compression pin 1 can drop smoothly, without people for going operation, save the time, efficiency is also high.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
