Description
Technical field
The utility model belongs to the tire-mold technical field, relates to a kind of exhaust structure of tire-mold.
Background technology
China's mould is with average speed increment more than 15% in recent years, higher than the average increment of domestic GDP more than one times.Wherein, due to the fast development of automobile industry, the development of tire-mold is very active.The development of China's Die Industry gives manufacturing industry with powerful support, simultaneously, manufacturing development has also promoted the development of Die Industry, China also becomes mould big producing country, China has entered the ranks of mould productive consumption big country, and the mould industry of China turns to independently new industry from dependence on import.
Mould is a kind of instrument that makes under external force blank become the product that given shape and size are arranged, be widely used in stamping-out, shaping and punching, die forging, metallic sintered products compacting, compression casting, and during the shaping of the compression moulding of the goods such as engineering plastics, rubber, pottery or injection moulding processes.Wherein tire-mold needs to vulcanize by tire-mold after the fetus moulding, in sulfidation, air in the tire-mold inner chamber needs to discharge, usually employing directly starts steam vent and carries out exhaust on tire-mold at present, after but the air of this kind method in tire-mold drains, liquid rubber also easily enters steam vent, thereby makes surface of tyre burr occur.
For the problems referred to above, Chinese utility model patent application (200920283549.0) discloses a kind of air exhaust jacket for tyre die, and this structure includes outer sleeve body and the stem stem that is through in the outer sleeve body endoporus; Outer sleeve body is stretched out at the forward and backward two ends of stem stem, and the stem stem front end is provided with block head, and block head and outer sleeve body endoporus front end are provided with the sealing conical surface that cooperatively interacts; The entity part that outer sleeve body is stretched out in the stem stem rear end is squeezed into the catch of flat, and the width of catch is greater than the diameter of outer sleeve body endoporus rear end; The stem stem outer race has a Compress Spring, on the block head inboard and the step in the outer sleeve body endoporus that press respectively the Compress Spring rear and front end, spring force can make stem stem move forward and above-mentioned block head is opened, this utility model can be arranged in the steam vent of tire-mold, and can avoid producing burr at surface of tyre.But break away from outer sleeve body during due to block head in exhaust, still have partially liq rubber and enter between block head and outer sleeve body this moment when gas drains, thereby affect the performance of this exhaust structure.
Summary of the invention
The purpose of this utility model is to have the problems referred to above for existing technology, has proposed a kind of exhaust structure of tire-mold, and the exhaust structure of this tire-mold can prevent effectively that rubber from entering steam vent, avoids affecting the exhaust performance of steam vent.
the purpose of this utility model can realize by following technical proposal: a kind of exhaust structure of tire-mold, offer steam vent on described tire-mold, slide and be inserted with valve rod in steam vent, the insertion end end of described valve rod is fixed with a sealing block that can cover steam vent, the other end has limiting section, it is characterized in that, be arranged with a tubular filter block on described valve rod, the inwall interference fits of the lateral wall of described filter block and steam vent, offer the filtering holes of some connection filter block one end end faces and lateral wall on described filter block, the other end of described filter block is pressed on sealing block, also be provided with the spring that can promote sealing block disengaging steam vent in steam vent, when sealing block breaks away from steam vent, above-mentioned filtering holes is facing to the inner chamber of tire-mold.
Steam vent is communicated with the tire-mold inner chamber with outside, and valve rod can move axially along steam vent, can stop rubber to enter steam vent during sealing block capping steam vent, can allow air pass through steam vent while breaking away from steam vent; The inwall interference fits of the lateral wall of filter block and steam vent, prevent that rubber from flowing into both gap from this; While having air in tire-mold, spring thrust makes sealing block break away from steam vent, and after air drained, rubber compressed sealing block and makes the sealing block Compress Spring, and sealing block covers steam vent, prevents that rubber from entering steam vent; Owing to offering the filtering holes that is communicated with filter block one end end face and lateral wall on filter block, therefore when sealing block broke away from steam vent, air can pass through steam vent from filtering holes, and rubber can't enter filtering holes, thereby prevent that rubber from entering steam vent, avoid affecting the exhaust performance of steam vent.
In the exhaust structure of above-mentioned tire-mold, described sealing block is round table-like, the end face that sealing piece area is less is connected mutually with the valve rod end, and both concentrics arrange, above-mentioned filter block one end is pressed on the sidewall of sealing block, and the external diameter of filter block is less than the diameter of the larger end face of sealing block area.Filter block is fixed on valve rod, and the external diameter of filter block is less than the diameter of the larger end face of sealing block area, and the diameter of the end face that namely the sealing block area is larger, greater than the diameter of steam vent, plays the covering sealing function.
In the exhaust structure of above-mentioned tire-mold, the inner aperture of described steam vent has the enlarging that matches with the sealing block sidewall.The side of sealing block is an inclined-plane, and the inwall of enlarging is also an inclined-plane, and both match.
In the exhaust structure of above-mentioned tire-mold, have an annular reducing on the outer end inner wall of described steam vent, above-mentioned limiting section is the convex annular edge on the valve rod sidewall, the external diameter on described convex annular edge is greater than the internal diameter of annular reducing.Valve rod is played position-limiting action, prevent that valve rod from being headed in the tire-mold inner chamber fully by spring.
In the exhaust structure of above-mentioned tire-mold, an end of described spring is pressed on the end face of filter block, and the other end is pressed on convex annular along upper.For the movement of valve rod provides power.
In the exhaust structure of above-mentioned tire-mold, described filtering holes circumferentially is evenly distributed on filter block.Make exhaust more even.
In the exhaust structure of above-mentioned tire-mold, offer screw on the less end face of described sealing block area, have a double-screw bolt on the end face of valve rod, described double-screw bolt spiral is connected in screw.Facilitate valve rod and sealing block to pack in steam vent, cleaning for convenience detach simultaneously.
Compared with prior art, the exhaust structure of this tire-mold has the following advantages:
1, owing to offering the filtering holes that is communicated with filter block one end end face and lateral wall on filter block, therefore when sealing block breaks away from steam vent, air can pass through steam vent from filtering holes, and rubber can't enter filtering holes, thereby prevent that rubber from entering steam vent, avoid affecting the exhaust performance of steam vent.
2, the side due to sealing block is an inclined-plane, and the inwall of enlarging is also an inclined-plane, and both match, so good sealing effect, simultaneously valve rod are played position-limiting action.
Therefore 3,, because sealing block is connected with screw by double-screw bolt with valve rod, facilitate valve rod and sealing block to pack in steam vent, while cleaning for convenience detach.
