As shown in Figure 2, segment 7 by multiple, such as form by 9 in the utility model, the plurality of segment 7 is configured to form ring-type segmented mold annularly.And the ring-type segmented mold be made up of multiple segment 7 can be changed to open state that each segment 7 as shown in Fig. 2 (a) opens mutually annularly and the mutual closed condition of touching annularly of each segment 7 as shown in Fig. 2 (b).Under the state that contiguity is closed condition, the state of the mould assembling of ring-type segmented mold completes.
Each segment 7 can be made up of more parts.
An external rings 4 is configured with in the foreign side of above-mentioned segment 7.By the movement of external rings 4, carry out side and the movement of foreign side in radial direction of each segment 7.
With reference to Fig. 3,4, said external ring 4 is moved up in a direction of axis direction and negative side thereof by the piston rod 8 via not shown cylinder.That is, external rings 4 moves at the above-below direction of Fig. 3, Fig. 4.More particularly, in the device of present embodiment, when making external rings 4 move from the below shown in the upper direction Fig. 4 shown in Fig. 3, each segment 7 is from side (be right direction at Fig. 3) movement in radial direction of the state shown in Fig. 3.Further, as shown in Figure 4, each segment 7 abuts with upper die 5, lower mould 6, and each segment 7 is touched each other annularly, and set of molds installs into.
Installed into by the set of molds of the ring-type segmented mold of each segment 7, tyre vulcanization is shaped on deck.
On the other hand, after finishing vulcanization forming, when making external rings 4 be moved upward from state as shown in Figure 4, each segment 7 is mobile to radial direction foreign side (being left direction on Fig. 4).Therefore, as shown in Figure 3, each segment 7 is opened, and mould assembling is opened by untiing.
Below, illustrate in further detail as the external rings 4 of main inscape of the present utility model, the structure of segment 7 and effect.
With reference to Fig. 5 ~ 9, the medial surface of said external ring 4, namely at the medial surface of the radial direction as the face relative with segment 7, forms the thin frusto-conical medial surface in front end upward, i.e. external rings side frusto-conical medial surface 41.
In a part for said external ring side frusto-conical medial surface 41, in the position relative with each segment 7, the external rings side being provided with the band shape extended in axial direction guides tabular surface 42.External rings side guides tabular surface 42 to be configured to tilt with having the same gradient with external rings side frusto-conical medial surface 41.
The lateral surface of the radial direction as the face relative with external rings 4 is configured to the thin frusto-conical lateral surface in front end upward by above-mentioned segment 7, that is, fan-shaped side frusto-conical lateral surface 71.This fan-shaped side frusto-conical lateral surface 71 is configured to the coniform curved surface of the gradient identical with said external ring side frusto-conical medial surface 41.
Be provided with at the circumferencial direction central portion of the part as above-mentioned fan-shaped side frusto-conical lateral surface 71 and guide tabular surface 72 in banded fan-shaped side in axial direction.This fan-shaped side guides tabular surface 72 to be configured to tilt with having the identical gradient with fan-shaped side frusto-conical lateral surface 71.
Said external ring side guides tabular surface 42 to guide tabular surface 72 to be configured to be in mutually relative position with fan-shaped side, when external rings 4 declines, until arrive the front of its final down position position between, carry out mutual face abutting.
Said external ring 4, each segment 7 can be made up of the metal such as iron, aluminium.
In addition, as shown in Figure 3,4, each segment 7 in order to make and cope match plate 2, action between mould board 3 are carried out smoothly, removably sandwiched copper alloy, ferroalloy, other the good sliding panel 9 of tufftride process.
Said external ring side guiding tabular surface 42 can use and form with the external rings side metallic plate 43 of external rings 4 main body split.At this moment, be formed in direction of principal axis in banded recess 44 in a part for said external ring side frusto-conical medial surface 41, with band shape, external rings side metallic plate 43 can be detachably installed at this recess 44 and be formed.
The upper surface being arranged on the external rings side metallic plate 43 of above-mentioned recess 44 becomes external rings side and guides tabular surface 42.
External rings side guide tabular surface 42 and the radial direction of external rings 4 be the face at right angle form.
Externally the installation of the recess 44 of ring side metallic plate 43 can use screw 10 grade, other installing mechanism detachably carries out.
In addition, external rings side metallic plate 43 can use the ferroalloy of the surface treatment such as copper alloy or tufftride process, other the material being suitable for sliding.
With reference to Fig. 9, said external ring side guides tabular surface 42 to be configured to this tabular surface 42 becomes the in-position entered than the arc track 41a of the concavity conical surface forming external rings side frusto-conical medial surface 41, more particularly, by making difference of height (section the is poor) S1 between the upper surface of external rings side metallic plate 43 (external rings side guides tabular surface 42) and recess 44 become more than zero, said external ring side guides tabular surface 42 to be configured in above-mentioned in-position.
By forming above-mentioned difference of height S1, the thickness of external rings side metallic plate 43 can be regulated, said external ring side can be regulated to guide the above-mentioned in-position of tabular surface 42.
Although make above-mentioned difference of height S1 be set to zero ground to form, the entry altitude that external rings side guides tabular surface 42 at this moment cannot be adjusted.
During by guiding tabular surface 42 to be configured in the in-position entered than the arc track 41a of external rings side frusto-conical medial surface 41 external rings side, external rings 4 abuts with each segment 7, can not be by external rings side frusto-conical medial surface 41 and fan-shaped side frusto-conical lateral surface 71, but guide tabular surface 42 and fan-shaped side to guide tabular surface 72 to carry out by external rings side.
That is, when carrying out mould assembling from open state to ring-type segmented mold, at least in the early stage, because external rings 4 is still in high position, thus the radius of curvature of the part of the external rings 4 contact with segment 7 compared with the radius of curvature of segment fully greatly.Thus, external rings 4 becomes the tendency guiding tabular surface 42 and fan-shaped side to guide tabular surface 72 to carry out face in the external rings side being in above-mentioned in-position to abut.
Symbol 11 is T blocks.This T block 11 passes through installing mechanism such as screw 12 grade, to run through the form of external rings side metallic plate 43, detachably on ring 4 mounted externally.
T block 11 is with embedding by the embedding (Swam of trip) formed in the state of the T word groove 13 formed in segment 7 side.
By making T block 11 and T word groove 13 swim embedding, outside plate 4 and each segment 4 link to swim embedding state.Embedding being attached at of trip between this outside plate 4 and each segment 7 makes segment 7 utilize when open state moves from closed condition.That is, by making outside plate 4 be moved upward, each segment 7 being embedded in this outside plate 4 by trip is moved by radial direction foreign side, and mould assembling is opened.
In Fig. 3, Fig. 4, symbol 14 is retainers.Symbol 15 is retainer grooves.The upper and lower bound of the movable range of said external ring 4 is determined by this retainer 14 and retainer groove 15.
With reference to figure 9, above-mentioned fan-shaped side guides tabular surface 72 to be configured to this tabular surface 72 becomes the going-back position retreated than the arc track 71a of the convex conical surface forming fan-shaped side frusto-conical lateral surface 71.That is, fan-shaped side guides tabular surface 72 to form with being cut into the tabular surface of string as by the circular arc of the convex conical surface forming fan-shaped side frusto-conical lateral surface 71.
By guiding tabular surface 72 to be configured in the going-back position retreated than the arc track 71a of the concavity conical surface of fan-shaped side frusto-conical lateral surface 71 on fan-shaped side, external rings 4 abuts with segment 7, can not be guide tabular surface 42 and fan-shaped side to guide tabular surface 72 by external rings side, but undertaken by external rings side frusto-conical medial surface 41 and fan-shaped side frusto-conical lateral surface 71.
That is, when carrying out mould assembling from open state to ring-type segmented mold, position near the position that set of molds installs, external rings 4 drops to the lowest height, and the radius of curvature of the part of the external rings 4 therefore contacted with segment 7 is reduced to the radius of curvature of segment 7 with about footpath.Thus, external rings 4 becomes and guides tabular surface 42 to be connected to external rings side to be in the fan-shaped side of going-back position to guide compared with tabular surface 72, and external rings side frusto-conical medial surface 41 is connected to the tendency of fan-shaped side frusto-conical lateral surface 71.
Above-mentioned fan-shaped side guiding tabular surface 72 also can use and form with the fan-shaped side metallic plate 73 of segment 7 main body split.At this moment, recess 74 can be formed at the cut surface 75 of the state that a part for coniform for above-mentioned fan-shaped side lateral surface 71 be cut, and on this recess 75, fan-shaped side metallic plate 73 is detachably installed.
The upper surface being installed in the fan-shaped side metallic plate 73 of above-mentioned recess 74 becomes fan-shaped side and guides tabular surface 72.
Although this fan-shaped side guides tabular surface 72 to be typically configured to become flush with above-mentioned cut surface 75, fan-shaped side guides tabular surface 72 also can give prominence to having difference of height S2 (with reference to Figure 10) relative to cut surface 75.When having difference of height S2, by the thickness of regulation fan body side metallic plate 73, above-mentioned fan-shaped side can be regulated to guide the going-back position of tabular surface 72.
In a word, fan-shaped side guides tabular surface 72 to be in the going-back position retreated than the arc track 71a of fan-shaped side frusto-conical lateral surface 71.
Fan-shaped side guides tabular surface 72 to form as the ground, face at a right angle with the radial direction (radial direction of external rings 4) of segment 7.
To the installation of the recess 74 of fan-shaped side metallic plate 73, the installing mechanisms such as not shown screw can be used detachably to carry out.
Fan-shaped side metallic plate can use the ferroalloy of the surface treatment such as copper alloy or tufftride process, other be suitable for slide material.
A pair fan-shaped side metallic plate that above-mentioned T word groove 13 can utilize above-mentioned recess 74 and be arranged on this recess 74 is to form T-shaped.
Use Fig. 3 ~ Fig. 8 that the action of the tyre vulcanized mould device of embodiment of the present utility model is described.
Now, as shown in Figure 3, when external rings 4 is in the position of upper, each segment 7 forming ring-type segmented mold is in the most foreign side of radial direction.As shown in Figure 5, the state that mould assembling is the most open is in.
Under the mould shown in Fig. 5 is assembled into the most open state, external rings 4 and each segment 7 are non-contacting state.That is, external rings side frusto-conical medial surface 41 and external rings side guide tabular surface 42 to be all in the state guiding tabular surface 72 to separate relative to fan-shaped side frusto-conical lateral surface 71 and fan-shaped side.
Each segment 7 is also in separated state each other.
Certainly, external rings 4 and each segment 7 are linked to swim embedding state by T block 11 and T word groove 13.
When the upper position making external rings 4 from the external rings 4 shown in Fig. 3 (release position of each segment) declines downwards, because the ring radius of external rings 4 part relative with each segment 7 diminishes, therefore, soon, as shown in Figure 6, external rings side guides tabular surface 42 to guide tabular surface 72 to abut (slipping) with fan-shaped side.
On the other hand, external rings side frusto-conical medial surface 41 maintains the state and non-abutting of separating relative to segment 7 side.
Guide tabular surface 42 to abut with segment 72 by external rings side, the promotion of the segment 7 produced by external rings 4, each segment 7 starts mobile inside radial direction.
The promotion of the segment 7 that the external rings 4 time thus produces, owing to being produce by guiding tabular surface 42,72 face each other to abut, so the stable posture of segment 7 in mobile, swings even if raising speed is also difficult to produce.That is, can prevent segment 7 and external rings 4 from colliding, damaging.
Along with the further decline of external rings, temporarily continue to guide tabular surface 42 and fan-shaped side to guide promotion square in the radial direction of each segment 7 under tabular surface 72 states abutted, that produced by external rings 4 in the state shown in Fig. 6 and external rings side.
When external rings 4 being dropped to position in the way in front of the lowest-order bit positions (closed position of each segment 7) arriving the external rings 4 shown in Fig. 4, even if between, because the ring of external rings 4 part relative to each segment 7 partly diminishes, therefore become the state shown in Fig. 7 soon.
Namely, external rings 4 and each segment 7 are except the face guiding tabular surface 42 and fan-shaped side to guide tabular surface 72 to carry out by external rings side abuts, and the line starting to be undertaken by external rings side frusto-conical medial surface 41 and fan-shaped side frusto-conical lateral surface 71 abuts.
When making external rings 4 decline further, eliminated by external rings side abutting of guiding tabular surface 42 and fan-shaped side to guide tabular surface 72 to carry out, both sides 42,72 separation.That is, external rings side guides tabular surface 42 to guide the promotion of tabular surface 72 to terminate to fan-shaped side.
And external rings side frusto-conical medial surface 41 carries out the promotion of direct line abutting to fan-shaped side frusto-conical lateral surface 71, each segment 7 is moved.
The promotion that the line undertaken by this external rings side frusto-conical medial surface 41 and fan-shaped side frusto-conical lateral surface 71 abuts, afterwards, continues to the closed position of segment 7.
When the lowest-order bit positions making external rings 4 drop to shown in Fig. 4, as shown in Figure 8, each segment 7 arrives its closed position, and the set of molds of ring-type segmented mold installs into.
