Abstract
The utility model discloses a framework of an injection-type rotation speed sensor, which comprises the framework, wherein, the middle part of the framework is provided with at least three supporting frames; the bottom of each supporting frame is provided with a projection block; a plurality of sealing sharp edges surround the supporting frames; the number of the supporting frames is three, wherein, two supporting frames are symmetrically distributed, and the other one is arranged between the two supporting frames. The supporting frames are arranged on the framework, so as to prevent the framework from sliding downwards during the secondary injection process; the sealing sharp edges surround the supporting frames, during the secondary injection process, high-temperature plastic is combined with the sealing sharp edges and blocks the channel inside and outside, so as to enable the sealing performance of the supporting frames to be better and to prevent the injected product from leaking. The framework can effectively solve the inside leakage problem after the secondary injection.
Description
Technical field
The utility model relates to the injection moulding formula speed probe that a kind of automobile, motorcycle are used, and is specifically related to a kind of skeleton of injection moulding formula speed probe.
Background technology
A kind of injection moulding formula speed probe that present automobile, motorcycle are used comprises plastic casing 1, skeleton 2, magnet 3, utmost point pin 4, electric terminal inserted sheet 5.When making this speed probe, as shown in Figure 1, earlier with skeleton 2 pre-injection moldeds, after again utmost point pin 4 and magnet 3, electric terminal inserted sheet 5 being assemblied in the two ends of skeleton 2 respectively, skeleton 2 after will assembling then is installed on the mould, carry out quadric injection mould and be shaped injection moulding plastic casing 1 as shown in Figure 2.As can be seen from Figure 1, do not support owing to have on the skeleton 2, in the quadric injection mould process, skeleton 2 can cause the product that produces defective along the sleeve 12 downward slippages of plastic casing 1 under the effect of injection pressure.
The utility model content
The technical problems to be solved in the utility model provides a kind of skeleton of injection moulding formula speed probe, and it can prevent slippage downwards in the quadric injection mould process, and the product after the injection moulding can not leak.
For solving the problems of the technologies described above, the technical solution of the skeleton of the utility model injection moulding formula speed probe is:
Comprise skeleton, described skeleton middle part is provided with and is no less than three bracing frames, and the bottom of support frame as described above is provided with projection, and support frame as described above is equipped with multi-turn and seals sharp limit.
Further, support frame as described above is equipped with the long narrow sharp-pointed sealing point of three circles limit.
Further, support frame as described above is three, and wherein two bracing frames are symmetrically distributed, and another bracing frame is arranged at the centre of two bracing frames.
The technique effect that the utility model can reach is:
The utility model skeleton is provided with bracing frame, prevents the downward slippage of skeleton in the quadric injection mould process; And on bracing frame, be equipped with long narrow sharp-pointed sealing point limit, and during quadric injection mould, high temperature plastics melts with the sharp fusing of margin of sealing and combines, the passage inside and outside having blocked, thus make the sealing property of bracing frame better, the product after the injection moulding can not leak.The utility model can solve sensor inner problem that leakage takes place behind quadric injection mould effectively.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the skeleton synoptic diagram that is equipped with utmost point pin, magnet and electric terminal inserted sheet in the prior art;
Fig. 2 is the structural representation of plastic casing in the prior art;
Fig. 3 is the structural representation of the skeleton of the utility model injection moulding formula speed probe;
Fig. 4 is the synoptic diagram with the injection molded injection moulding formula speed probe of the utility model;
Fig. 5 is the leakage point synoptic diagram of plastic casing.
Among the figure, 1 plastic casing, 2 skeletons, 3 magnet, 4 utmost point pins, 5 electric terminal inserted sheets, 12 sleeves, 22 skeletons, the sharp limit of 220 sealings, 221,222,223 bracing frames, 224,225,226 projections, 110 leakage points.
Embodiment
As shown in Figure 3, Figure 4, the skeleton of the utility model injection moulding formula speed probe comprises skeleton 22, and skeleton 22 middle parts are provided with three bracing frames 221,222,223, and the angle between per two bracing frames is 90 °.Promptly wherein two bracing frames 222,223 are symmetrically distributed at skeleton 22 middle parts, and another bracing frame 221 is arranged at the centre of two bracing frames 222,223.Each bracing frame bottom respectively is provided with projection 224,225,226.
This structure skeleton is provided with three bracing frames, in the quadric injection mould process, be supported on the mould by the projection on three bracing frames 221,222,223 224,225,226, can make skeleton 22 can access effective support, prevent the downward slippage of skeleton in the quadric injection mould process.But in the injection moulding process, the strong point place of projection 224,225,226 on mould can't melt fully, therefore behind quadric injection mould, the contact position of projection 224,225,226 and mould is still exposed outside, make the speed probe of injection mo(u)lding have leakage point 110, as shown in Figure 5, outside aqueous vapor or other media enter sensor internal from leakage point 110 easily.This leakage point 110 promptly is the strong point of projection 224,225,226 on mould.
Therefore, the utility model is equipped with the long narrow sharp-pointed sealing point of multi-turn limit 220 at each bracing frame, and the skeleton of injection moulding formula speed probe shown in Figure 3 is provided with the sharp limit 220 of three circle sealings.
The utility model skeleton is provided with bracing frame 221,222,223, and on bracing frame 221,222,223, be equipped with long narrow sharp-pointed sealing point limit 220, during quadric injection mould, high temperature plastics and the sharp limit of sealing 220 adhere, blocked inside and outside passage, thereby make the sealing property of bracing frame 221,222,223 better, the product after the injection moulding can not leak.The utility model can solve sensor inner problem that leakage takes place behind quadric injection mould effectively.
