The present invention has the advantages of short operation time, high productive efficiency, easy production, easy scale production, and the appearance quality of the silica gel finger stall blood oxygen probe is easy to be ensured.
Description
Technical field the present invention relates to the molding of silica gel goods and the post processing of molded goods, be particularly related to and send material to model, core, by method and the mould that heating makes it to merge, relate in particular to the method and the mould of encapsulation connecting line in the silica gel blood oxygen probe.
Background technology is in the life-information monitor, and the oxygen saturation measurement instrument is one of them crucial measurement module.The accessory of oxygen saturation measurement instrument is a blood oxygen probe.Electric in device in the composition of blood oxygen probe except comprising, also comprise the lead that some support the shell of these electronic devices and are used to transmit signal, shell is generally used the ABS material, and these materials belong to hard material, make various screens easily, each parts are fitted together with screw.Therefore traditional blood oxygen probe manufacture method is: make parts respectively, by the later stage operation each parts are assembled into a complete blood oxygen probe.A kind of blood oxygen probe of mentioning as U.S. Pat 4685464 " DURABLE SENSOR FOR DETECTINGOPTICAL PULSES ", this blood oxygen probe is made from multiple components, these parts comprise upper cover, press from both sides a plurality of parts compositions such as lid, spring, last pad, underlay down, and overall structure is quite complicated.A kind of blood oxygen probe that U.S. Pat 6388240 " SHIELDED OPTICAL PROBE AND METHOD HAVING A LONGEVITY INDICATION " is mentioned also comprise upper cover, down press from both sides lid, spring, go up a plurality of parts such as pad, underlay.And adopt with the silica gel material is that the blood oxygen probe that main material is made can save each parts of mentioning in the above-mentioned patent, but because silica gel is a kind of softish material, in making the blood oxygen probe process, be not easy the lead that is used to transmit signal that also belongs to flexible material is embedded into the inside of silica gel material, existing method is to be reserved with groove and line hole on the surface of silica gel material, then line is put into groove, on groove, pour into glue then, after glue curing, then dabbling glue is enclosed in lead in the layer of silica gel.If adopt existing method to seal these wire casings and line hole, following shortcoming arranged:
1) since line hole on the fingerstall and wire casing along two side cablings of fingerstall, and glue has flowability, when glue was filled into wire casing and line hole, glue overflowed easily, the quality of influence probe outward appearance, and inconvenient operation influence production efficiency.
2) again because the wire casing on the fingerstall is not on a smooth plane, therefore be in not suprafacial line hole and wire casing can not pour into glue simultaneously, otherwise glue can be in the effect current downflow of gravity, cause glue to flow out metallic channel, must wait and translate into another side again after wherein the glue of one side has been done and pour into glue, and blood oxygen probe has several faces need put glue, glue needs a period of time from being filled into to solidify, the cycle of therefore making probe is long, is unfavorable for producing in enormous quantities.
Above method is when in enormous quantities the manufacturing, and efficient is inevitable low, and the probe presentation quality is not easy to be guaranteed.
Summary of the invention the objective of the invention is to avoid the deficiencies in the prior art part and the method and the mould that propose a kind of blood oxygen probe sealing wire of silica gel finger sleeve, method of the present invention and mould at first on fingerstall the design a kind of outside bonded trough structure, in trough, seal line then.The method of envelope line is: lead is worn line-entering hole or the wire casing of packing into after, fill these line hole and wire casings with the silica gel raw material of manufacturing fingerstall material, put into then and the identical mould hot pressing of finger-stall; In hot pressing, the silica gel material that is filled into wire casing vulcanizes under the effect of heat, merges fully with the fingerstall body then, complete being closed of wire casing; Because the profile and the fingerstall of hot pressing die are identical, so the envelope line fingerstall after the hot pressing not only is completely enclosed within lead in wire casing and the line hole but also the fingerstall outward appearance is also unaffected.Owing to adopted mould, so the fingerstall outward appearance after the sealing keeps good.Owing to adopted hot pressed method to finish the sulfuration of packing material, so the operating time of this technology is short, the production efficiency height.The silica gel finger sleeve blood oxygen probe presentation quality of this method is guaranteed easily, and is easy to large-scale production.
It is as follows that the present invention solves the problems of the technologies described above the technical scheme of taking:
A kind of method of sealing line in the silica gel finger sleeve blood oxygen probe said method comprising the steps of:
A., metallic channel is set within silica gel finger sleeve;
B. prepare a strand, this strand comprises main section, left side shoulder line segment, a left side line segment, left the end of a thread and right shoulder line segment right line segment and right the end of a thread;
C. prepare an envelope line mould, this envelope line mould comprises patrix, core, and counterdie;
D. with behind the strand insertion wire groove, dispose into the silica gel raw material at notch;
E. insertion wire bundle and the silica gel finger sleeve of inserting the silica gel raw material are embedded envelope line mould;
The envelope line mould that f. will contain silica gel finger sleeve is inserted the heater baking;
G. baking finishes, and takes out silica gel finger sleeve.
The described metallic channel of step a comprises left side shoulder groove, a left side groove, right shoulder groove and a right groove; The notch of described left side shoulder groove, right shoulder groove is opened the inboard at silica gel finger sleeve; The notch that groove and right groove are propped up in a described left side is opened the outside at silica gel finger sleeve.
The described patrix of step c has a upper mould cave, and the form of the form of upper mould cave and the silica gel finger sleeve first half is coincide; Described counterdie has die cavity, and the form of the form of following die cavity and silica gel finger sleeve Lower Half is coincide; The form of described core and silica gel finger sleeve inner chamber form are coincide.
