Abstract
The utility model relates to a piston mold for hydraulic brake cylinder, which comprises an upper mold cover and a lower mold cover, an upper punch, a cavity and a mandrill which tips the finished products out of the cavity. The utility model is characterized in that the upper and lower mold covers are fastened to the upper punch and the cavity respectively. The upper mold cover is connected with the punch handle extending outside, and the lower cover is fixed on a fixing structure by a fastener. The bottom of the upper punch matches with the inner diameter of the piston in appearance. A mold chamber matching with the appearance of the piston is arranged in the center of the cavity, a through hole is provided on the bottom of the mold chamber. The mandrill is fixed on a suspending pull plate, and the mandrill tips the finished products of the cavity through the through hole. A suspending pull plate is connected with a punch handle by two pull rods. The utility model processes pistons with new mold can simplify the working procedure, reduce the loss of the cost and raw material and guarantee the quality of products.
Description
Technical field
The utility model relates to a kind of mould that is used for making the hydraulic braking wheelcylinder piston.
Background technology
The hydraulic vehicle braking wheelcylinder piston is the automobile common components, and the profile of this piston is cylinder, and one is processed with the depression circular hole.At present this piston adopts the aluminium compression molding process mostly, but with the piston of this processes moulding, except the cost height, wear no resistance, aluminium will pollute operating environment in fusion process, be harmful to health.In addition, the method that adopts aluminium bar or the direct machining moulding of iron staff is also arranged, but the greatest drawback that exists with this method is that stock utilization is low, manufacturing procedure is complicated, include operations such as blanking, end face tack, perforating, bore hole, thereby cause production efficiency very low, and after multiple operation processing, the difficult control of dimensional accuracy, processing differences is bigger, can't guarantee consistency 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 for making the hydraulic braking wheelcylinder piston at above-mentioned prior art present situation, by this mould can improve piston production efficiency, reduce production costs, guarantee product quality.
It is to realize by the mould of following structure that the utility model solves the problems of the technologies described above the technical scheme that is adopted: the push rod that it includes upper and lower die sleeve, upper punch, die and is used for the finished product in the die is ejected, it is characterized in that: described upper punch is contained on the Upper Die-sleeve, the low profile of upper punch and piston inner diameter shape match, on the die shank that described Upper Die-sleeve is connected with the outside links to each other; Described die is located on the fixture, and fix by lower die-sleeve, described die central upper portion place is provided with the die cavity that matches with piston profile, cavity bottom is provided with through hole, described push rod is fixed on the suspension arm-tie, can offset with the semi-finished product in the die by through hole, the suspension arm-tie is connected with die shank by two pull bars.
Described Upper Die-sleeve and die shank are assembled into one by thread connection.
Described die is contained on the mould bases that fixes with fixture, and described lower die-sleeve and mould bases are integral by thread connection.
Compared with prior art, advantage of the present utility model is: adopt the utility model mould to come machining piston, both simplified operation, reduced production cost and raw material loss, guaranteed product quality simultaneously.

The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Hydraulic braking wheelcylinder piston mould of the present utility model as shown in Figure 1-Figure 3, it includes Upper Die-sleeve 2, lower die-sleeve 5, upper punch 3, die 10 and push rod 8, described upper punch 3 is installed on the Upper Die-sleeve 2, its lower end profile is consistent with the internal diameter shape of piston.On die shank 1, die shank is connected with forcing press described Upper Die-sleeve 5 by thread connection.
Described die 10 is contained on the mould bases 9, and mould bases 9 fixes by bolt and workbench 6.Be provided with internal and external screw thread between described lower die-sleeve 5 and the mould bases 9, both are integral by thread connection.Described die 10 central upper portion places be provided with face with above-mentioned upper punch and with the corresponding to die cavity 11 of piston profile, and be provided with central through hole 12 in cavity bottom.
Described push rod 8 is positioned at workbench 6 belows, is fixed on the arm-tie 7, and arm-tie 7 suspends and is connected on two pull bars 4, and two pull bars 4 link to each other with die shank 1.Die shank 1, push rod 8 and arm-tie 7 pump under the effect of forcing press like this, manufactured workpiece in the die 10 are outwards ejected by push rod with this.
Adopt above-mentioned mould to come the process of compaction piston as follows: at first according to the specification requirement of piston, iron staff is cut into required stock, the length of this blank conforms to the length of piston; Then above-mentioned blank is put into die 10 after high-frequency heating, under the effect of die shank 1 at forcing press, make upper punch 3, pull bar 4, push rod 8 and arm-tie 7 move vertically downward, upper punch 3 is pressed into blank and finishes putting in place of piston profile and internal diameter physical dimension in the die cavity; Under the effect of forcing press, die shank 1 drives upper punch 3 and returns, and drives pull bar 4, arm-tie 7 and push rod 8 simultaneously and moves upward then, and push rod 8 enters in die 10 bottom through-holes, and when moving to top dead centre, push rod 8 outwards ejects manufactured workpiece in the die 10.Handle and promptly make profile and be cylinder, the finished product piston that the depression circular hole is arranged by this semi-finished product piston being done tack finishing more at last.
Because adopt iron material directly to utilize the mould extrusion modling, thus the piston that adopts the aluminium die cast to make more at present, cost is lower, intensity is better, and production efficiency is higher.
