Abstract
The utility model relates to the technical field of dies, in particular to die cores and a sleeve for a compression pin head forming die. The die cores and the die sleeve are used for clamping the compression pin and comprise a die core group, wherein the die core group adopts a split type and is formed by matching two symmetrically arranged die cores; a counterbore used for placing a compression pin is formed in a matching position of the die core group; and the outer wall of the die core group is sleeved with a die sleeve used for clamping the die core group. The die cores and the die sleeve for the compression pin head forming die clamp the compression pin therein through adopting the split type die core group; the die core group is in a trapezoid block shape, and is connected with a molding surface of the die sleeve to clamp the die core group; meanwhile, the die core group can be extracted conveniently, and accordingly, the compression pin can be taken out conveniently; therefore, the die cores and the die sleeve are simple in structure, can be used in various processes for forming the compression pin head, other clamping dies are not needed to be developed, the cost is reduced, and meanwhile, the efficiency is improved due to the convenience in taking out of the compression pin.
Description
Technical field
The utility model relates to technical field of mold, especially a kind of pin head mould core rod die sleeve that compresses.
Background technology
In the automobile industry, use always on the automobile brake mouth and also namely compress pin to suspension rod, traditional processing for compressing the pin head needs jumping-up, operations such as blanking, different operations are finished compressing the difference processing of pin head, because compressing pin is component of rod category, so need can process after compressing pin and being fixedly clamped, to guarantee the quality of product, and in the tradition processing, have the problem that clamps weak effect for the mould that compresses pin head moulding clamping, simultaneously, in different operations, process and also can need different clamping molds when compressing pin, thereby bring problem on the cost, and also there is manual trouble in the blanking that compresses pin, and efficient is difficult to promote.
The utility model content
The technical problems to be solved in the utility model is: compress pin clamping weak effect in the prior art in order to solve, compress the pin finished product and take off time-consuming technical problem, a kind of pin head mould core rod die sleeve that compresses is provided, can toss about in bed in each operation, to use, need not change different anchor clamps at different operations.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of pin head mould core rod die sleeve that compresses, be used for clamping and compress pin, comprise the core rod group, described core rod group is two formulas of breaking off with the fingers and thumb, formed by two symmetrically arranged core rods cooperations, form one in the cooperation place of core rod group and be used for placing the counter sink that compresses pin, be set with one on the described core rod group outer wall for the die sleeve that clamps the core rod group.
In order can better the core rod group to be fixed and the taking-up of core rod group, described die sleeve is cuboid, the front-back top of die sleeve has the breach that runs through described front-back, described die sleeve middle part has notch, described notch cross section is trapezoidal, described core rod group is trapezoidal shape, and the core rod group is that profile is connected with the notch of die sleeve.
In order to cooperate Mould Machining, the big end surfaces of described core rod group two edges 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 that compresses on the pin head mould patrix is inserted in this jack, and die sleeve is withstood by the depression bar of patrix, and the process that die sleeve descends is that the core rod group rises.
As preferably, the gradient on two inclined-planes of the angle of inclination of described jack and core rod group is 80 °.
The beneficial effects of the utility model are, mould of the present utility model uses the core retainer plate that compresses the moulding of pin head by adopting two formula core rod groups of breaking off with the fingers and thumb, to compress pin is clipped in wherein, because the core rod group is the trapezoid block shape, by be connected the effect that clamps the core rod group of playing with the die sleeve profile, simultaneously also can conveniently withdraw from the core rod group, thereby compressing pin just can conveniently take out, thereby the utility model is simple in structure, can in the different operations that compress the moulding of pin head, share, need not reduce cost at other clamping molds of exploitation, the facility that compresses the pin taking-up has simultaneously also increased efficient.

The specific embodiment
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.
Embodiment
Shown in Fig. 1～4, this mould core retainer plate that compresses the moulding of pin head, be used for clamping and compress pin 1, comprise core rod group 2, core rod group 2 is two formulas of breaking off with the fingers and thumb, formed by two symmetrically arranged core rods 3 cooperations, form one in the cooperation place of core rod group 2 and be used for placing the counter sink 4 that compresses pin 1, be set with one on core rod group 2 outer walls for the die sleeve 5 that clamps core rod group 2, die sleeve 5 is cuboid, the front-back top of die sleeve 5 has the breach 52 that runs through front-back, die sleeve 5 middle parts have notch 51, notch 51 cross sections are trapezoidal, and core rod group 2 is trapezoidal shape, and core rod group 2 is connected for profile with the notch 51 of die sleeve 5, core rod group 2 big end surfaces two edges 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, takes out and be convenient to cooperate for the core rod group that is is easier to compress the pin molding procedure from die sleeve, and the gradient on two inclined-planes of the angle of inclination of jack 21 and core rod group 2 is 80 ° among the design.
When compressing pin 1 jumping-up, when the utility model is placed counterdie, be equipped with in the counter sink 4 and compress pin 1, the downward punching press of patrix, head into jumping-up in the counterdie jumping-up chamber compressing pin 1, when compressing pin 1 and eject station, during the downward punching press of patrix, compress pin 1 owing to acting on of patrix moves down a bit of in the core rod group 2, when when flattening station, the utility model is withstood in the downward punching press of patrix, finishes the flattening work that compresses pin 1 head, drop when namely compress pin 1 finished product at the blanking station, during the downward punching press of patrix this moment, insert the blanking bar of patrix in two jacks 21 of core rod group 2, die sleeve 5 is withstood by push rod, owing to there is gradient, then the core rod in the core rod group 23 is by separately, and compressing pin 1 and can dropping smoothly of moulding at this moment operated for going without the people, saved the time, efficient is also high.
