Description of the Invention: [Technical Field] The present invention relates to an exhaust device, particularly to a tire molding die, which is used to remove air in a cavity while forming a tire in a cavity. The surface of the formed tire does not produce burrs. [Prior Art] • The process of tires is from the start of raw materials to the finished tires. The process of continuous production of sighs is “sequentially automated.” The production process will be processed in sequence, extrusion, molding, and vulcanization. In the molding process, a green tire is formed, and then the melon machine is used for the vulcanization process to control the preset time and temperature. At this time, the tread formation is formed at the same time. ^When the vulcanization process is carried out, the raw tire is first put into the mold. The airbag bag in the mold is made of the raw tire toward the cavity from the inside. With the high temperature and high steam, the heat and the Lili are used to combine the rubber molecules with the sulfur molecules. The rubber of the green tire has better elasticity and durability, and the final shape and pattern of the tire are also formed at this stage. When the sulfur is finished, the tire is taken out, that is, the vulcanization process is completed. During the process of vulcanization, the airbag inside the raw tire will gradually discharge the gas between the outside of the raw face and the cavity, so that the outside of the green tire can be completely attached to the die and cut into m 'Therefore, the refilling device will be provided with a number of venting holes; the knife gas and the upper part will enable the gas in the cavity to be smoothly discharged through the venting hole; - Generally speaking, this i-gas action will take the opportunity to view the row. The stomata, resulting in 3 201132482 such as burr-like bristles, and therefore the reason why the appearance of the tire tread used in the time is covered with the lanugo. Further study on the venting device of the vulcanized mold, which can be divided into "with a fetal hair type" and "without the tire type" depending on the formation of the lanugo, among which the "female-type" venting device such as the US 4th, 436, 497 According to the patent disclosed, an exhaust group is arranged in the vent hole, mainly to reduce the exhaust hole diameter, so that the tire hair formation is small and short; and the "no tire-type" exhaust gas vulcanization mold can be The tire will not be formed on the raw tire, so the operation of removing the lanugo can be avoided after the vulcanization operation, and the finished product of the tire is more beautiful. According to the conventional "non-tire-type" vulcanization mold venting device, as disclosed in the U.S. Patent No. 6'923'629 B2, the utility model of the present invention is incorporated in the outer casing of the venting opening of the mold and inserted into the outer casing. The valve body head in the center through hole and the valve body insertion portion are formed into a body, and a spring force is applied to the valve body, a spring around the interposer insertion portion, and a lower end of the upper body insertion portion. The age of the whole body in the vertical direction can be substantially controlled, and the outer casing_the central through hole is tapered, that is, the larger the upper direction, and the smaller the lower direction, the smaller the upper and lower The upper end edge portion of the central through hole is in point contact with the tilting body and the tilting angle, and is formed to be inclined to the angle of the edge portion of the central through hole; the angle of the side of the valve body head is formed at an acute angle, and The inclination angle of the upper end edge portion of the center through hole is formed to be an obtuse angle. 201132482 • [Description of the Invention] In the above-mentioned "fetal-free" vulcanization mold exhausting device structure, when the inflow of rubber into the central through hole of the exhaust device casing cannot be completely blocked, if it is discharged through the discharge The shortest air path prevents the oak from staying in the air path. P ’ and right as much as possible to ensure a large space in the central through hole, which can improve the durability of the exhaust gas and the k-long exhaust device. On the other hand, the structure is formed in the central L-hole of the outer casing to be tapered; the inner technique is more upward, and the inclined angle of the valve body head which is in point contact with the upper end of the central through-hole is different from each other. Therefore, it is possible to improve the discharge capacity of the air and to suppress the inside of the rubber ventilator. However, this structure is to set the venting needle to the passage N of the exhaust gas, which will hinder the smoothness of the exhaust gas. In addition, the exhaust group has many components, and the assembly cost is labor and materials, and the manufacturing cost is also high; The inventor believes that there is still considerable room for improvement in the venting structure of the vulcanized mold, and in view of the foregoing problems, another technically and functionally superior tire vulcanizing mold venting structure is provided. ί (Technical means for solving the problem) In view of the above, the exhaust group structure of the tire mold disclosed in the present invention comprises: a tire mold 'in which a -Chenglong hole is formed, which has a vent hole. Passing through the molding cavity to a through hole outside the tire mold, the exhaust hole is formed with an exhaust reaming near the molding cavity; and an exhaust group having a positioning member is disposed thereon In the middle section of the venting hole, the positioning member forms a small-exhaust passage, and the venting needle is disposed in the center of the positioning member, and one end thereof is provided with one of the inclined surfaces of the venting reaming Oblique taper, in each of the positioning members and the oblique 201132482 'cone is provided - elastic member, mentioning (four) row of Lai Xi ^ ^ the exhaust passage and the elastic force of the needle-shaped needle, · New, will be the same material, It can be used for smoothness, and the design of the hole and the tapered taper can make the filling operation after the exhausting, and the tightness of the elastic member has better stability. (Compared with the efficacy of the prior art) ^ The main purpose of the invention is to provide a row structure of the tire mold, the structure design of the silk Weitong Lai Wei coffee separation, so that the Wei channel is unblocked; The gas valve body or the venting needle is hindered, and has a smoother effect. ~, / The second aspect of the present invention is to provide a tire group structure of a tire mold, which is a tooth. At the end of the venting pin at the other end of the slinging piece, the design of the venting pin can reduce the assembly of the components and the material and maintenance time, and can effectively reduce the manufacturing cost. / The re-purpose of the present invention is to provide an exhaust group structure of a tire mold, which is provided with a conduit seat between the exhaust needle and the positioning member, and the elastic member is disposed therein, and the dust is stuck in the The occurrence of the elastic member can make the expansion and contraction movement of the elastic member relatively stable and smooth, so that the displacement action of the venting needle is more accurate, and the reversion effect is better. A further object of the present invention is to provide an exhaust group structure of a tire mold which is used for a vulcanization mold without a tire. After the green tire is formed, the surface does not generate lanugo, the tire hair trimming process can be eliminated, and the trimming process is eliminated. The occurrence of a cut on the surface of the green tire can reduce the labor cost. [Embodiment] 6 201132482 First, please refer to the first to fourth figures, the exhaust group structure of a tire mold provided by the present invention, comprising: a tire mold (ίο), and a tire mold (10) Several exhaust groups (20) within. The tire mold (1〇) is formed therein with a molding cavity (丨丨) having a plurality of vent holes (10) through which the fines (1) are passed to the through holes of the tire mold (10); An exhaust reaming hole (13) is formed in a portion of the vent hole (12) adjacent to the molding cavity (1〇). The exhaust group (20) is disposed at a predetermined portion of the middle portion of the exhaust hole (12) by a positioning member (21), and the positioning member (21) has a triangular triangular shape with a slightly triangular cross section. (211), and the outer diameter edge thereof is effectively abutted against the inner diameter edge wall of the vent hole (12); the positioning member (21) has a cross section of a convex triangular portion and a gap surface thereof. The inner diameter edge wall of the vent hole (12) together form an exhaust passage (212), so that two exhaust passages (212) are formed; the exhaust needle (22) is threaded through the positioning member (21). The center can be moved from the upper and lower lines, and the airing needle (22) has a tapered portion (221) at its end and a piercing end (222) at the other end; the piercing end is provided with the positioning. After the piece (21), the piercing and exposing portion (222) is pressed and deformed to form a fixed end portion (223); the inclined taper portion (221) is at the venting pin (22) after moving, it can be adhered to the inclined surface of the exhaust reaming hole (13); the inclined taper portion (221) is continuously extended with a small outer diameter and has a stepped shape - the flange (24) Forming a contact surface (241) with the inclined taper portion (221); one side of the positioning member (21) The smaller outer diameter continuously extends one of the stepped card edges (25), forming a snap surface (251) with the positioning member (21); the catheter seat (26) is hollow tubular, and its two ends are respectively Abutting on each of the abutting surface (241) and the engaging surface (251); an elastic member (23) having a plurality of ends of the 201132482 abutting the ends of the flange (24) and the card edge (25) The elastic surface of the venting needle (22) is provided on the rim surface; the outer diameter of the end surface of the inclined taper portion (221) is larger than the outer diameter of the positioning member (21). By means of the above-mentioned members, the exhaust passage (212) and the exhaust needle (22) are designed to separate the holes, so that the exhaust gas can be made more smooth, and at the same time, each of the exhaust reaming holes (13) and the inclined taper portion The design of (221) allows for better selection of the filler after the venting operation, and the actuation of the elastic member (23) has better stability. In order to further understand the structural features, technical means and expected effects of the present invention, the mode of use of the present invention will be described as follows: When the creation is set, the exhaust group (2〇) needs to be assembled in advance. Referring to the second to third figures, the venting needle (22) is sequentially passed through the elastic member (23), the catheter seat (26), and the positioning member (21), and then the wearing end is (222) The external road is deformed by the pliers or other hand tools at the position of the positioning member (21), so that the flat fixed end portion (223) is assembled; at this time, the elastic member (23) The two ends of the catheter seat (26) are respectively abutted against the end faces of the flanges (24) and the card edge (25), and the two ends of the catheter seat (26) can effectively abut against the abutting surfaces (241) and the clamping ends. Face (251) 'The card edge (25) can also be threaded over the inner diameter edge of the catheter seat (26). The exhaust group (20) of the foregoing set is disposed in the exhaust hole (12), and the positioning member (21) is inserted into the outer end of the exhaust reaming (13) to The predetermined portion, that is, the assembly is completed; at this time, the inner diameter edge of the vent hole (12) abuts against the three convex rounded corners (211) of the positioning member, and the outer edge of the positioning member (21) is not convexly rounded. The planar shape forms the exhaust passage (212) together with the inner diameter edge of the exhaust hole (12). When using this creation, please refer to the fourth to eighth figures. When the exhaust unit (2〇) 201132482 is in the exhaustable state, the exhaust needle (22) and the exhaust reaming (13) There is a distance to form a passage. Therefore, when exhausting, gas enters through the exhaust reaming hole (13), and passes through the passage between each of the duct seat (26) and the exhaust hole (12), and then passes through the exhaust passage. (212) Final discharge; when the green tire (4〇) gradually abuts against the molding cavity (11) in the vulcanization process, the green tire (40) pushes the exhaust needle (22) to the top, so that The inclined taper portion (221) is in close contact with the exhaust reaming hole (13), and the green tire (4〇) is completely close to the molding cavity (11), and each of the exhaust groups ( 2〇) that is, it is not exhausted. The green tire (40) does not overflow the exhaust hole (12) from between the exhaust reaming hole (13) and the exhaust pin (22), and also because of the exhaust. The inclined taper portion (221) at the end of the needle (22) blocks the exhaust reaming hole (13) of the vent hole (12), so that the green tire does not form the bristles at the vent hole (12). After the vulcanization operation is completed, the elastic member (23) is pushed back to the original position by the external force release, even if the inclined taper portion (221) and the exhaust reaming hole (13) ) into a natural state with a spacing. Each of the exhaust passages (212) of the present invention is disposed on the positioning member (21) in an independent manner and is separated from the piercing portion of the exhaust needle (22). This design can solve the conventional structure. When the gas is exhausted, the gas discharge space is occupied by the exhaust valve and is too small, and the up and down displacement of the exhaust valve makes the exhaust gas less smooth, so the present invention has a better and smoother exhaust effect. Furthermore, when the exhaust group (2〇) of the present invention is assembled in series, the elastic member (23), the catheter seat (26), and the positioning member are sequentially disposed by the exhaust needle (22). (21), the exposed end (222) is pressed and deformed, and the venting needle (22) is positioned on the positioning member (21) without being elasticized by the elastic member (23). Disengagement; this 201132482 - structural design: but reducing the assembly of components, also saving 1 time and material costs, can greatly reduce the manufacturing cost; at the same time, the catheter seat (26) of the present invention provides the miscellaneous pieces (23 The dust set in the thin 阙 mold is stuck on the elastic member (23) to reduce the ruin or stretch caused by the health card on the $ 发生 _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ In order to be smooth and stable, the action of extracting and venting the gas in the south is relatively reliable, and the venting needle ((2) has a better returning effect. It is worth mentioning that the outer diameter edge ring of the positioning member (21) of the present invention is provided with three convexities. Rounded corners (211) 'This-structural design, mainly for the ribbed surface to form each of the convex rounded corners (2) 1) 'So you can make one side, two sides, four sides, five sides, etc. as needed In this way, the exhaust passage (212) formed between the convex fillets (2) 1} is formed in three aspects, and the exhaust space is large and more gas permeable; on the other hand, the use of each The area of the side edge of the convex 81 corner (211) abutting against the air venting hole (10) is reduced, and the assembly area can be more labor-saving. In addition, the technical feature of the convex shape rounded corner (211) of the hair shape is The group is located in the Weikong ((2), the miscellaneous capacity is inspected inside and is easier to assemble; the other can also be used in each of the convex rounded corners (2) to process the waste flower to increase the friction and make the positioning The effect of the component (8) being stuck in the venting hole (12) is more stable. The design of the venting reaming hole (13) and the inclined taper portion (221) of the present invention is such that the preset inclination is used to make the two When it is in the exhaust state, it can be tightly closed. When the degree of adhesion is high, the tire will not produce the tires or the burrs during the vulcanization operation, and the subsequent depilation operation can be dispensed with, and the above-mentioned "the tire mold is disclosed in the present invention. Exhaust gas structure", 201132482 • Storage and supply-face reduction effect and private tire growth reduction structure, using separate exhaust passages and exhaust The wearing portion makes the exhaust space unobstructed by the row of pins and its action, and the positioning member has a large exhaust space, which can increase the gas effect. In addition, the exhaust group has fewer components, which can reduce the manufacturing cost. And won the ^ - high practical tires plus rhyme reduction structure, so that the overall industry has practical cost-effectiveness, and its structure has not been seen in the books or public use, Cheng Fu Hefa wealth application requirements, riding fishing The Bureau of Wei, as soon as the patent is granted, is to be prayed. It is necessary to explain the above, and the above is the specific embodiment of the present invention and the application thereof, the function of the invention is changed according to the concept of the present invention. Except for the spirit of the specification and the drawings, it shall be within the scope of the invention and shall be combined with Chen Ming.
