Abstract
The utility model relates to an attachment structure of a tire vulcanization forming die, in particular to a tire die air vent valve mounted in an air vent of a tire forming die. The tire die air vent valve comprises an outer sleeve body and a core column embedded in an inner hole of the outer sleeve body in a penetrating manner; the front end and the rear end of the core column extend out of the outer sleeve body, a seal head is arranged at the front end of the core column, and sealing conical surfaces matched with each other are arranged at the front ends of the seal head and the inner hole of the outer sleeve body; limited blocks with the maximum outer diameters larger than the diameter of the rear end of the inner hole of the outer sleeve body are arranged at the rear end of the core column, and the entity of the core column at the rear section is split into two halves through a slot; and the periphery of the core column is sleeved by a compression spring, the front end and the rear end of the compression spring are pressed on the inner side of the seal head and steps inside the inner hole of the outer sleeve body respectively, and the spring force enables the core column to move forward and open the seal head. The utility model can be mounted in the air vent of the tire die, and avoid raw edges on the tire surface.
Description
Technical field
The utility model relates to the accessory structure of tire curing forming mold, specifically is the tire-mold air bleeding valve in a kind of steam vent that is installed in tire forming mold.
Background technology
On the mould of rubber tyre, usually a plurality of steam vents to be set, to guarantee raw material moulding smoothly in mould.In the prior art, in steam vent, settle a stainless exhaust flange usually, this exhaust flange is a simple cylindrical shell, a small amount of sizing material can overflow from exhaust flange in the tire building process, make the tire product surface of final molding produce circumferential column burr, this can increase the material consumption of the manufacturing of tire on the one hand, and the pruning to burr has also increased machining period on the other hand, reduce production efficiency, also easily surface of tyre has been caused damage during pruning.
Summary of the invention
Technical problem to be solved in the utility model is, provides in a kind of steam vent that can be installed in tire-mold, and can avoid producing at surface of tyre the tire parting line venting valve of burr.
Tire-mold air bleeding valve of the present utility model 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 stem stem rear end is provided with the limited block of maximum outside diameter greater than outer sleeve body endoporus rear end diameter, and the entity at the stem stem back segment is divided into two halves by a slit simultaneously; The stem stem periphery is with a compression spring, and on the block head inboard and the step in the outer sleeve body endoporus that press respectively compression spring rear and front end, spring force can make stem stem move forward and above-mentioned block head is opened.
The utility model uses on tire-mold, substitute original stainless steel gas borehole jack, exhaust phase at tire building, gas in the mould can normally be discharged, and after sizing material is full of mould, can stop sizing material excessive from steam vent, thereby avoided producing burr, improved product quality at surface of tyre.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, this tire-mold air bleeding valve includes outer sleeve body 1 and the stem stem 2 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 3, and block head and outer sleeve body endoporus front end are provided with the sealing conical surface 4 that cooperatively interacts; The stem stem rear end is provided with the limited block 5 of maximum outside diameter greater than outer sleeve body endoporus rear end diameter, and the entity at the stem stem back segment is divided into two halves by a slit 6 simultaneously.During assembling, stem stem 2 penetrates from outer sleeve body endoporus front end, limited block 5 outside by endoporus the time is squeezed, because the existence of slit, make limited block produce inside strain, thereby the limited block 5 that makes the stem stem rear end can pass the outer sleeve body endoporus and stretch out from the outer sleeve body rear end, stretches out simultaneously behind the outer sleeve body because the elastic recovery of limited block can limit stem stem and withdraw from forward.The stem stem periphery is with a compression spring 7, and on block head 3 inboards and the step 7 in the outer sleeve body endoporus that press respectively compression spring rear and front end, spring force can make stem stem move forward and above-mentioned block head is opened.
In the utility model use, be positioned in the steam vent 9 of tire-mold 8, in the tire building process, at exhaust phase, under the effect of compression spring 7, block head 3 is opened, and the gas in the die cavity can discharge through the endoporus of outer sleeve body; When exhaust finishes, after sizing material was full of die cavity, the block head 3 that sizing material can press stem stem 2 front ends overcame spring force and moves backward, and sealing surface is closed, and sizing material can't be overflowed, thereby can not form burr at surface of tyre.
Claims (1)
1. tire-mold air bleeding valve includes outer sleeve body (1) and is through stem stem (2) 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 (3), and block head and outer sleeve body endoporus front end are provided with the sealing conical surface (4) that cooperatively interacts; The stem stem rear end is provided with the limited block (5) of maximum outside diameter greater than outer sleeve body endoporus rear end diameter, it is characterized in that: the entity of stem stem (2) back segment is divided into two halves by a slit (6); The stem stem periphery is with a compression spring (7), and on block head (3) inboard and the step (7) in the outer sleeve body endoporus that press respectively compression spring rear and front end, spring force can make stem stem move forward and above-mentioned block head is opened.
