Abstract
A mold for hydraulic braking base pump piston comprising an upper die and a counter die is characterized in that the upper die comprises a drift pin with the shape of the under-part matching with the piston groove and a die body for fixing the drift pin, wherein the die body is connected with the drift handle connected with the external body, the counter-die is fixed on fixity by a fastening piece, a die cavity matched with the shape of the piston, a positioning structure for work-piece and a upper and lower straight slot having a matched shape of the drift pin are arranged on the counter-die, the upper and lower straight slot is arranged at the upper and lower part of the die cavity correspondingly and communicated with the die cavity, a through-hole is arranged at the bottom of the die cavity and a check shoulder is arranged between the die cavity and the through-hole. Manufacturing the slot of the piston whit the mold of the utility model simplifies the process, reduces the manufacturing cost and ensures the quality of the product at the same time.
Description
Technical field
The utility model relates to a kind of mould that is used to make the hydraulic braking master cylinder piston.
Background technology
The hydraulic braking master cylinder for automobile piston is the automobile common components, and the profile of this piston is roughly cylindrical, and through hole is axially arranged, and scabble both sides, along an axial kidney slot that runs through is arranged on the cylinder length direction.Be to mill moulding mostly to the kidney slot on this piston at present by brill.Therefore there is the problem that production efficiency is low, cutter damages easily, causes the piston production cost very high.Adopt simultaneously and bore the miller skill, the difficult control of the dimensional accuracy of groove, processing differences is bigger, can't guarantee the quality of product.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of mould that is used to make the hydraulic braking master cylinder piston at above-mentioned prior art present situation, by this mould can improve piston production efficiency, reduce production costs, guarantee product quality.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: it includes upper die and lower die, it is characterized in that described patrix includes low profile and piston groove shape drift that matches and the die sleeve of fixing this drift, wherein on the die shank that die sleeve is connected with the outside links to each other; Described counterdie is fixed on the fixture by securing member, wherein this counterdie is provided with the upper and lower groove that the die cavity, workpiece positioning structure and the shape that match with piston profile and drift match, the length direction of this upper and lower groove is consistent with the direction of axis line of die cavity, correspondence is located at the upper and lower of die cavity and connects with die cavity, and at cavity bottom through hole is arranged, and and this through hole between shoulder block is arranged.
Described workpiece positioning structure is to be located at two jacks that counterdie top and die cavity connect.
Described Upper Die-sleeve and die shank are thread connection.
Compared with prior art, advantage of the present utility model: come the groove of machining piston by the utility model mould, both simplified operation, reduced production cost, guaranteed product quality simultaneously.
Description of drawings

Fig. 2 is the schematic perspective view of the utility model embodiment.
Fig. 3 is the perspective exploded view of Fig. 2.
The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
In conjunction with Fig. 1-shown in Figure 3, hydraulic braking master cylinder Piston mould of the present utility model includes upper die and lower die, described patrix has a drift 3 and a die sleeve 2, and drift 3 is installed on the die sleeve 2, and its lower end profile is consistent with the internal diameter shape of piston groove to be processed.Described patrix thread connection is on die shank 1, and die shank 1 is connected with forcing press.
Described counterdie 4 fixes by bolt and workbench 5, counterdie 4 is provided with and the corresponding to die cavity 43 of piston profile, and be provided with in cavity bottom and be used for through hole 42 that the workpiece after processed is ejected, simultaneously in order to limit workpiece, it is positioned in the die cavity, the aperture of this through hole is less than the aperture of die cavity, to constitute the shoulder block of a spacing usefulness.Described counterdie 4 tops are provided with the groove 41 that connects with die cavity, and the length direction of this groove 41 is consistent with the direction of axis line of die cavity 43, the drift 3 of groove 41 on the patrix, and internal diameter shape and drift profile are suitable.Described drift 3 promptly passes through workpiece 6 punch process in 41 pairs of die cavities of groove 43, and the waste material of going out is extruded by groove, falls by the opening on the workbench 5 again.Because the profile of piston is cylindrical, therefore in order to prevent workpiece to be processed at the die cavity intrinsic deflection, the top of counterdie also is provided with 44, two location of jack of two location usefulness and inserts respectively in the jack with plug-in unit, and is inconsistent with the portion of scabbling 61 of workpiece 6 heads respectively.
Adopt above-mentioned mould to come the process of compaction piston groove as follows: at first will put into counterdie die cavity 43 through the workpiece to be processed after the intermediate frequency low-grade fever 6, under the effect of die shank 1 at forcing press, drift 3 moves vertically downward, workpiece 6 punching presses of drift 3 in 41 pairs of die cavities of groove of counterdie 4, the waste material that stamps out is come out through the opening of workbench by groove; Then under the effect of forcing press, die shank 1 drives drift 3 and returns, and enter the workpiece that will process with a push rod from the through hole of counterdie and eject outside the die cavity this moment.By the piston groove of above-mentioned mould drawing, not only bright and clean slitter edge free, dimensional accuracy height, and production efficiency height, the instrument cost is low.
Claims (3)
