Abstract
The invention relates to an air valve sealing cap and a manufacturing method of the air valve sealing cap. The air valve sealing cap comprises a cap body, a ring of neck part with shrunken size is arranged at the end part of the cap body, a sealing gasket is arranged in the neck part, and the sealing gasket and the cap body are manufactured through injection successively so that the adhesive strength is formed between the sealing gasket and the cap body.
Description
Technical field
The present invention relates to the tire tube valve of motor tire, especially relate to tire tube valve seal cap and preparation method thereof.
Background technology
Fig. 1 illustrates a kind of existing tire tube valve seal cap structure.With reference to shown in Figure 1,10 is tire tube valve, and 11 is seal cap cap body, and cap body 11 is threaded with tire tube valve 10.In the end of cap body 11, be provided with a circle packing seal 12, play the sealing to the mouth of tire tube valve 10.The material of packing seal 12 is rubber.Correspondingly, cap body 11 forms flange 13 in packing seal inner ring end, compress packing seal.The shortcoming of this structure is, 13 of flange compress the packing seal inner ring, and packing seal 12 is still deviate from easily.
The injection moulding process of above-mentioned existing tire tube valve seal cap is as follows, at first uses vulcanization of rubber equipment making rubber pad, makes the plastic cap body with injection machine then.Manually rubber pad is packed in the cap body afterwards, with flange equipment cap body flange is pushed down rubber pad again.Though this technology can be made many simultaneously with porous mold when rubber pad and cap system are done, when packing packing seal and flange in the cap body, need pack flange one by one, the low and poor reliability of efficient one by one into.Simultaneously, there is above-mentioned shortcoming in the seal cap of made.
Summary of the invention
Technical matters to be solved by this invention provides a kind of improved tire tube valve seal cap, and the method for making of this seal cap.
The present invention is that to solve the problems of the technologies described above the technical scheme that adopts be to propose a kind of tire tube valve seal cap, comprise a cap body, has the neck that a circle size is dwindled in the end of this cap body, and be provided with a packing seal in this neck, sealing pad and this cap body are successively to make to make between sealing pad and the cap body by injection moulding to have bonding force.
In one embodiment of this invention, the sealing pad is made with thermoplastic elastomer.
In one embodiment of this invention, the neck of this cap body is the outer ring of pushing down the sealing pad.
The present invention proposes a kind of method for making of tire tube valve seal cap in addition, may further comprise the steps: one or more packing seals are made in injection moulding; Each packing seal is inserted in the mould of cap body again, form one or more cap bodies by injection moulding, wherein this cap body forms neck that a circle size dwindles with fixing sealing pad at sealing pad place.
In one embodiment of this invention, the material of sealing pad is that thermoplastic elastomer is made.
In one embodiment of this invention, the neck of this cap body is the outer ring of pushing down the sealing pad.
Tire tube valve seal cap of the present invention is owing to have certain adhesive between packing seal and the cap body when forming the neck injection moulding, the situation that packing seal is not deviate from, by contrast, existing seal cap is owing to be to pack in the later stage, and only rely on flange to push down the inner ring of packing seal, packing seal is in use deviate from easily.Method for making of the present invention can be made a plurality of seal caps simultaneously, though and existing method for making can be made many packing seals and cap body simultaneously with porous mold when rubber pad and cap system are done, but when packing packing seal and flange in the cap body, need pack into one by one, flange one by one, the low and poor reliability of efficient.
Description of drawings
For above-mentioned purpose of the present invention, feature and advantage can be become apparent, below in conjunction with accompanying drawing the specific embodiment of the present invention is elaborated, wherein:
Fig. 1 illustrates existing a kind of tire tube valve seal cap structure.
Fig. 2 illustrates the tire tube valve seal cap structure of one embodiment of the invention.
Fig. 3 A-3C illustrates the tire tube valve seal cap of one embodiment of the invention and makes flow process.
The specific embodiment
Fig. 2 illustrates the tire tube valve seal cap structure of one embodiment of the invention.With reference to shown in Figure 2, this tire tube valve seal cap comprises a cap body 21, has screw thread in the cap body 21, is used for being threaded with tire tube valve 10.Have the neck 22 that a circle size is dwindled in the end of cap body 21, and be provided with a packing seal 23 in this neck.The degree of depth of neck 22 is enough to push down the outer ring of packing seal 23 at least.Further, packing seal 23 and cap body 21 are successively to make by injection moulding, that is to say that packing seal 23 is the necks 22 that are directly injection-moulded in cap body 21, so the bonding force of sew is arranged between the two.Like this, owing to the power and the cohesive force that prevent from neck deviating from, packing seal is difficult for deviating from.
In order to adapt to the requirement of Shooting Technique, packing seal 23 is preferably uses thermoplastic elastomer, and for example TPE (Thermoplastic Elastomer) makes.
The method for making of the tire tube valve seal cap of the embodiment of the invention is described below with reference to Fig. 3 A-3C.As shown in Figure 3A, packing seal 23 is made in first injection moulding.Method is to carry out injection moulding at first mold 31 that is used for injection moulding packing seal 23.First mold 31 can packing seal 23 of injection moulding, the also a plurality of packing seals 23 of injection moulding simultaneously.
Then shown in Fig. 3 B, packing seal 23 is inserted second mold 32 for cap body 21, on the basis of packing seal 23, form cap body 21 by injection moulding.As can be seen, by the cap shape that second mold 32 limits, littler on radial wall thickness in the position of arrow A indication.Therefore in the seal cap finished product shown in Fig. 3 C, cap body 21 forms the neck 22 that a circle size is dwindled at packing seal 23 places.The benefit that forms neck 22 is that neck 22 is enough to push down the outer ring of packing seal 23, and the quadric injection mould by carrying out on the basis of packing seal 23, makes to have bonding force between packing seal 23 and the cap body 21.
In preferred embodiment, packing seal 23 is to use thermoplastic elastomer, and for example TPE (Thermoplastic Elastomer) makes, more to adapt to Shooting Technique.
In sum, the tire tube valve seal cap of the embodiment of the invention is owing to have certain adhesive between packing seal and the cap body when forming the neck injection moulding, the situation of not deviating from, by contrast, existing seal cap is owing to be to pack in the later stage, and only rely on flange to push down the inner ring of packing seal, packing seal is in use deviate from easily.The method for making of the embodiment of the invention can be made a plurality of seal caps simultaneously, though and existing method for making can be made many packing seals and cap body simultaneously with porous mold when rubber pad and cap system are done, but when packing packing seal and flange in the cap body, need pack into one by one, flange one by one, the low and poor reliability of efficient.
Though the present invention discloses as above with preferred embodiment; right its is not in order to limiting the present invention, any those skilled in the art, without departing from the spirit and scope of the present invention; when can doing a little modification and perfect, so protection scope of the present invention is when with being as the criterion that claims were defined.
