Abstract
The utility model provides a four-cavity die of a traction motor spherical hinge. The four-cavity die comprises an upper die, a middle die, a bottom die and a bottom die base plate, wherein four working cavities are formed in the corresponding positions on the upper die, the middle die, the bottom die and the bottom die base plate; meanwhile, a rubber injection plug fixing plate with a hole in the middle is also arranged on the upper die; a rubber injection hole identical with the size of the hole on the rubber injection plug fixing plate is formed on the upper surface of the upper die; the bottom of the rubber injection hole is communicated with the working cavities; a rubber injection plug is arranged in the position corresponding to the rubber injection hole; the rubber injection plug is as high as the upper surface of the rubber injection plug fixing plate; besides, upper and bottom die inserts are also arranged in the working cavities; and a spacer is arranged beside a three-petal die beside the middle die position of the working cavities. The four-cavity die has simple process, is convenient to process and easy to assemble and can effectively improve the work efficiency and product quality.
Description
Technical field
The utility model relates to the ball pivot mould applications, is specially a kind of traction electric machine ball pivot four cavity moulds that original molding type list chamber sulfurizing mould can be modified as the injecting type combination die.
Background technology
Ball hinged rubber elastic element is the compound damping element of using always of a kind of rubber-metal, can be widely used in various vibration dampings place.Wherein, rubber traction ball pivot is as the critical component of transmitting tractive and brake force between locomotive car body and the bogie, when requiring to reduce the quality of ball pivot body as far as possible, need also to realize that flexible drawing is to reach the purpose of vibration and noise reducing, thereby, effective carrying size of rubber traction ball pivot, the ess-strain amount of rubber inside are had relatively high expectations.But in the prior art, the mould for preparing this special elastic element all designs unreasonable usually, its production efficiency is low, percent defective is high, operation intensity height, also higher to workman's operant level requirement, simultaneously, though the ball pivot of producing can satisfy the job requirement under the general job situation, produce the zone of concentrating at stress, the structure of ball pivot and quality just are difficult to meet the demands, therefore, needing necessary this type of mould further improves.
The utility model content
The technical problem that the utility model solved is to provide a kind of traction electric machine ball pivot four cavity moulds, and is low to overcome the production efficiency that existing this type of rubber shock-absorbing component mold exists in process of production, the unsettled defective of quality.
The technical problem that the utility model solved realizes by the following technical solutions:
Traction electric machine ball pivot four cavity moulds, comprise patrix, middle mould, bed die and bed die backing plate, wherein, described patrix and middle mould are symmetrical structure, bed die and bed die backing plate then are arranged in parallel within middle mould bottom successively, patrix, middle mould, have four working chambers on the correspondence position of bed die and bed die backing plate, simultaneously, on described patrix, also be provided with an injecting glue plug fixed head, this injecting glue plug fixed head is provided with and the corresponding perforate in working chamber position, and have on the upper surface of patrix one with injecting glue plug fixed head on the consistent hole for injecting glue of pore size of perforate, the hole for injecting glue bottom is communicated with working chamber, in addition, also be provided with an injecting glue plug at the hole for injecting glue place, injecting glue plug position and injecting glue plug fixed head upper surface are contour.
In the utility model, be provided with also in the described working chamber cavity that patrix is inserted, bed die is inserted, and at the other partition that is provided with of three other lobe moulds of the middle mould position side of working chamber.
In the utility model, be provided with fixed connecting piece between described patrix and middle mould, middle mould and bed die, bed die and the bed die backing plate.
In the utility model, the plate body both sides of described patrix, middle mould are provided with hangers, and bed die then is provided with hangers in a side, in order to make things convenient for pickup and to carry out the lock out operation of adjacent mould.
In the utility model, fastening between described injecting glue plug and the injecting glue plug fixed head by holding screw.
Beneficial effect: the utility model is simple in structure, easy to use, can increase work efficiency greatly, and installation and removal are very convenient, and mould itself is not yielding, can use repeatedly, so can obviously reduce construction costs.
Description of drawings
Fig. 1 is the cross-sectional view of preferred embodiment of the present utility model.
The specific embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Preferred embodiment referring to traction electric machine ball pivot four cavity moulds of Fig. 1, in the present embodiment, comprise patrix 2, middle mould 3, bed die 4 and bed die backing plate 5, the plate body both sides of patrix 2, middle mould 3 are provided with hangers, bed die 3 then is provided with hangers in a side, in order to make things convenient for pickup and to carry out the lock out operation of adjacent mould.And on each adjacent layer structure of patrix 2, middle mould 3, bed die 4 and bed die backing plate 5, be provided with fixed connecting piece, wherein, be connected, be connected by bed die awl guide pin bushing 9 and bed die awl guide pillar 8 between middle mould 3 and the bed die 4 by patrix guide pillar 6 and middle mould guide pin bushing 7 between patrix 2 and the middle mould 3, and between bed die 4 and bed die backing plate 5, except that being provided with bed die backing plate fixed leg 10, also being provided with pulling block sub-assembly 22 and connecting on its side side.
In patrix 2, middle mould 3 and bed die 4, be provided with working chamber; in the described working chamber; patrix is inserted and 17 is fixed on the patrix 2; bed die is inserted and 11 then is fixed on the bed die 4 by insert set bolt 13 and alignment pin 11 of bed die; and on the plane of middle mould 3; except that being provided with the movable pulling block 21 of three lobe moulds 15 and three lobe moulds, also at the other partition 18 that is provided with of movable pulling block 21 sides of three lobe moulds.
And on patrix 2, also be provided with injecting glue plug fixed head 1, and have on the upper surface of patrix 2 one with injecting glue plug fixed head 1 on the consistent hole for injecting glue of pore size of perforate, the hole for injecting glue bottom is communicated with working chamber, and be provided with an injecting glue plug 19 at the hole for injecting glue correspondence position, injecting glue plug 19 positions and injecting glue plug fixed head 1 upper surface are contour, and at the other Glass cement squeezing device 31 that is provided with of side.
