Abstract
The utility model discloses an automobile brake vibration reduction ring die comprising an upper die, a lower die and a middle die, wherein, the cavity structure of a vibration reduction ring is formed after the assembly of the upper, the lower and the middle dies. The automobile brake vibration reduction ring die is characterized in that a circle of upper core shaft is arranged downwards in the upper die, a circle of lower core shaft is arranged in the lower die in correspondence to the upper die, and a clearance is reserved between the upper core shaft and the lower core shaft after die assembly. When the automobile brake vibration reduction ring die is used for processing, the upper core shaft is aligned with the lower core shaft after die assembly, and a vibration reduction hole with an interlayer in the middle is obtained through the formation of the upper and the lower core shafts. Therefore, neither the length of the upper core shaft nor the length of the lower core shaft is larger than or equal to half of the length of the original core shaft, so that the separation of the upper and the lower core shafts from the vibration reduction ring is facilitated during demoulding after formation, and the core shafts are prevented from being fractured. Therefore, the processing is easier, and the processing cost is reduced.
Description
Technical field
The utility model relates to the mfg. moulding die of the damping ring that uses in a kind of braking automobile mechanism.
Background technology
In the braking automobile mechanism of a Ford Motor, adopt a kind of damping ring member to carry out vibration damping.Existing damping ring member, its structure comprise a cylindrical body 1 as shown in Figure 1, and direct-axis is to the uniform circle vibration damping hole 2 that is provided with on described cylindrical body 1 barrel, and described vibration damping hole 2 is a through hole.This damping ring obtains with formed in mould processing mode for adopting elastomeric material.During use, utilize the elasticity of rubber self and the structure in vibration damping hole to carry out vibration damping.
This damping ring, adding man-hour, adopt the mould molding mode to obtain, its existing processing mold structure is: comprise upper die and lower die and middle mould, can form the cavity structure of damping ring behind upper die and lower die and the middle mould matched moulds, to being arranged with a circle mandrel, the locating hole corresponding with mandrel is set in counterdie in the patrix, the vibration damping hole of locating and obtain by the mandrel moulding damping ring in the locating hole is inserted in the mandrel lower end during matched moulds.
Adopt the processing of this mould structure, because vibration damping hole depth and narrow makes mandrel long and thin, during the demoulding, mandrel ruptures easily after moulding.So have processing inconvenience, the easy loss of mould causes the high defective of processing cost.
The utility model content
At above-mentioned deficiency, technical problem to be solved in the utility model is to provide a kind of easy to process, the braking automobile damping ring mould that processing cost is low.
In order to solve the problems of the technologies described above, adopted following technical scheme in the utility model:
A kind of braking automobile damping ring mould, comprise upper die and lower die and middle mould, form the cavity structure of damping ring behind upper die and lower die and the middle mould matched moulds, its characteristics are, go up mandrel to being arranged with a circle in the patrix, the corresponding mandrel of going up is provided with circle mandrel down in the counterdie, goes up between mandrel and the following mandrel behind the matched moulds and leaves the gap.
Adopt mould of the present utility model to add man-hour, behind the matched moulds, the vibration damping hole of middle band interlayer is aimed at and obtained by upper and lower mandrel moulding to last mandrel just with following mandrel.The length that goes up mandrel and following mandrel like this is all less than half of former mandrel, so after the moulding during demoulding, convenient upper and lower mandrel breaks away from from damping ring, mandrel is easy fracture not.So reduced difficulty of processing, reduced processing cost.Going up mandrel during matched moulds can not consume because of touching with following mandrel yet.Simultaneously, the damping ring that this Mould Machining goes out only has one deck interlayer at middle part, vibration damping hole, can not impact effectiveness in vibration suppression substantially, can satisfy the vibration damping requirement.
In sum, than prior art, damping ring mould of the present utility model has easy to process, the low advantage that causes low processing cost of mould loss.
Description of drawings
Fig. 1 is the structural representation of the described damping ring of background technology.
Fig. 2 is the cutaway view of the utility model mould.
The specific embodiment
Below in conjunction with the drawings and specific embodiments structure of the present utility model is described in further detail.
During concrete enforcement, as shown in Figure 2, a kind of braking automobile damping ring mould, comprise patrix 3, counterdie 4 and middle mould 5, form the cavity structure 8 of damping ring behind patrix 3, counterdie 4 and middle mould 5 matched moulds, wherein, go up mandrel 6 to being arranged with a circle in the patrix 3, the corresponding mandrel 6 of going up is provided with circle mandrel 7 down in the counterdie 4, goes up between mandrel 6 and the following mandrel 7 behind the matched moulds and leaves the gap.
The damping ring that adopts this damping ring mould to make can leave an interlayer at middle part, vibration damping hole, but this interlayer is very thin, can not impact effectiveness in vibration suppression substantially, can satisfy the vibration damping requirement.
Claims (1)
1. braking automobile damping ring mould, comprise upper die and lower die and middle mould, form the cavity structure of damping ring behind upper die and lower die and the middle mould matched moulds, it is characterized in that, go up mandrel to being arranged with a circle in the patrix, the corresponding mandrel of going up is provided with circle mandrel down in the counterdie, goes up between mandrel and the following mandrel behind the matched moulds and leaves the gap.
