Specific embodiment
The technical solution of the utility model is further described below in conjunction with the accompanying drawings, but claimed scope is not limited to
It is described.
As shown in Figure 2, Figure 3, Figure 4, position limiting structure during a kind of movable iron core of electromagnetic valve adhesive described in the utility model, bag
Coil rack 1, coil 2, dynamic iron core 3 and fixed core component 5 are included, the coil 2 is wrapped on coil rack 1, the dynamic iron core 3
The central through hole two ends of coil rack 1 are respectively arranged in fixed core component 5, are set between the dynamic iron core 3 and fixed core component 5
There is return spring 4, the fixed core component 5 includes fixed core 6 and gag lever post 7, and the gag lever post 7 is fixedly connected with fixed core 6,
And gag lever post 7 is extended in the centre bore of dynamic iron core 3, and spacing is kept with each face in the centre bore of dynamic iron core 3.
The fixed core 6 is provided with central through hole 8, and gag lever post 7 is plugged in the central through hole 8 of fixed core 6, and and fixed core
6 are fixedly connected.
Step 9 is provided with the central through hole 8 of the fixed core 6, fixed core 6 is provided with the locating slot coordinated with step 9.
The gag lever post 7 adopts plastics injection mo(u)lding together with fixed core 6.
6 end face of fixed core and dynamic iron core 3 are smaller than between 3 centre bore bottom surface of 7 top of the gag lever post and dynamic iron core
Spacing between end face.
Embodiment
During processing, fixed core 6 is first processed, central through hole 8 is bored to dynamic iron core 6, and step 9 is reserved in central through hole 8, such as
Shown in Fig. 4.Hole wall surface roughness no requirement (NR) to central through hole 8, or requirement can be very low, meanwhile, it is logical at center to step 9
Axial location in hole 8 also no requirement (NR), with most convenient batch production as principle.After processing obtains fixed core 6, by fixed core
6 are fixed to mold center, hot melting plastic is injected in central through hole 8 and mould and is molded, cooling shaping, you can obtained
Whole fixed core component 5.In fixed core component 5, gag lever post 7 can be ensured by mould beyond the length dimension L of 6 end face of fixed core,
So as to can quickly obtain meeting the fixed core component 5 of part technical requirements.
During work, after electromagnetic valve coil 2 must be electric, dynamic iron core 3 overcomes the elastic force of return spring 4 under electromagnetic force,
To 6 one lateral movement of fixed core.Due to being smaller than 6 end face of fixed core between 3 centre bore bottom surface of 7 top of gag lever post and dynamic iron core
With the spacing between 3 end face of dynamic iron core, when 7 top of gag lever post is contacted with 3 centre bore bottom surface of dynamic iron core, 3 end face of dynamic iron core with
Can't contact between 6 end face of fixed core, so as to ensure that the gap between dynamic iron core 3 and fixed core 6.And due to gag lever post 7
With attachment structure obtained by the injection of fixed core 6, axial float will not occur between gag lever post 7 and fixed core 6, be less susceptible to pier
The problem of thick and gag lever post 7 bending, it is ensured that the job stability of electromagnetic valve.When electromagnetic valve dead electricity, dynamic iron core 3 is in return spring
4 elastic force effect is lower to reply initial position, and electromagnetic valve quits work.
The technical program processing technology is easily guaranteed that production efficiency is high, and part process cycle is short, low cost, structure letter
Single, product quality is stable.
Gag lever post 7 adopts the injection mo(u)lding together with fixed core 6, so can without the gag lever post A21 of the former press-fit structure of processing,
Reduce the press-fitting operation of parts, good manufacturability, injection mo(u)lding efficiency high.
