Description

TECHNICAL FIELD

[0001] The utility model belongs to tire manufacturing technical field, concretely relates to a solid tire ejection connecting device. BACKGROUND

[0002] At present, when vulcanizing non-solid tire, the center mechanism is used to move and push the lower rim to eject the tire, but when vulcanizing solid tire, the solid tire is first produced and then fixed on the rim, without operation fulcrum in the middle, so the demolding operation is difficult and unstable, often damaging the rim and mold, and affecting the tire quality.

[0003] According to the related data, the patent CN203637052U discloses a mold ejection device for solid tire vulcanization production, which designs the lifting component connected by pull pins and the stress component with stress teeth in the steel ring, controls the solid tire ejection by the mold ejection device composed of the two, and ensures the overall ejection of the solid tire. After the lifting component of the mold ejection device aligns with the stress teeth of the lower rim, the rotating ring is clamped, the stress component is on the lower rim, the lower rim is located in the deep part of the mold, and when the lifting component cooperates with the steel ring, the operation space is small, on the other hand, after the lifting component cooperates with the steel ring, the heat transfer is fast, and there is a risk of scalding when operating the lifting component. At the same time, the stress component of the stress teeth is on the lower rim, which increases the processing difficulty of the lower rim.

[0004] The patent CN211518209U discloses a solid tire mold ejection device, which comprises a workbench for placing a mold, a quick locking mechanism on the workbench for fixing a lower mold, a rotary head, and a lifting mechanism fixed to the workbench for driving the rotary head to move along the mold axis. The rotary head is provided with at least one limit block which moves reciprocally along the radial direction of the mold and is used for clamping and releasing the lower rim, and the rotary head is also provided with a driving mechanism for driving the limit block to move. The device can be quickly locked and released with the lower rim, which is convenient for mold ejection and replaces manual operation to improve work efficiency. The device needs to hoist the mold to the platform, increase the locking mechanism, occupy a large space, and has high cost. At the same time, the stress component of the stress teeth is on the lower rim, which increases the processing difficulty of the steel ring.

[0005] Based on the above analysis and combined with the company's situation, in order to solve the problem of difficult and unstable demolding operation, a device which is easy to operate, simple in structure, easy to process and low in cost needs to be developed to meet the production of existing solid tires.

The gland 5 includes a first gland 51 and a second gland 52, the first gland 51 and the second gland 52 are symmetrically arranged, and the first gland 51 and the second gland 52 are detachably connected through bolts.

[0046] The gland 5 is fixed on the clamp 6 through screws, the gland 5 and the clamp 6 are coaxially arranged, the symmetric surface 25 of the first gland 51 and the second gland 52 is a gland symmetric surface 25, the symmetric surface 24 of the first clamp 61 and the second clamp 62 is a clamp symmetric surface 24, the gland symmetric surface 25 and the clamp symmetric surface 24 are arranged at an angle θ, the angle θ is in the range of 30 degrees to 90 degrees, and the symmetric surface of the gland 5 and the symmetric surface of the clamp 6 are arranged at an angle θ, which ensures the stability of the fixed connection of the gland 5 and the clamp 6.

[0047] In the embodiment, the first and second clamps 61 and 62 are fastened to the plunger end of the external ejection mechanism 26 by bolts, then the reverse buckle tray structure 16 on the connecting rod 4 is buckled to the convex ring 19 of the clamp 6, and finally the front and rear pressure covers 51 and 52 are installed on the reverse buckle tray structure 16 and fixedly connected together by bolts, and the pressure cover 5 is fixedly connected to the clamp 6 by screws.

[0048] The installation process of the solid tire ejection connecting device is as follows:

[0049] Firstly, the upper mold and the upper bead of the solid tire 22 are removed by hoisting, at this time, the solid tire 22 and the lower bead 1 are located in the lower mold 23, in order to realize the separation of the solid tire 22 from the lower mold 23 and the lower bead 1, the solid tire ejection connecting device of the embodiment is adopted, specifically as follows:

[0050] As shown in Figure 1 The pressure ring 2 and the force ring 3 are positioned by the pin 11, and the force ring 3 and the pressure ring 2 are fixed on the flange plate 10 on the lower bead 1 by screws, so that the force ring 3 and the pressure ring 2 are fixedly connected to the lower bead 1.

[0051] Then, the bottom of the clamp 6 is installed on the plunger end of the external ejection mechanism 26 and fastened by screws, then the reverse buckle tray structure 16 of the connecting rod 4 is sleeved on the convex ring 19 of the clamp 6, and finally the pressure cover 5 is fixed on the clamp 6, and the reverse buckle tray structure 16 is located in the rotating cavity 8.

[0052] The working process of the solid tire ejection connecting device is as follows:

[0053] The plunger head of the external ejection mechanism 26 starts to rise, driving the clamp 6, the pressure cover 5 and the connecting rod 4 to rise together, when the cross force teeth 15 at the top end of the connecting rod 4 approach the bottom end of the force ring 3, the rising action is paused, the rotating rod 18 is inserted into the through hole 17, the connecting rod 4 is rotated, the cross force teeth 15 are aligned with the cross groove structure 12, so that the cross force teeth 15 can pass through the cross groove structure 12 into the inside of the force cavity 7 without obstruction; after entering the inside of the force cavity 7, the connecting rod 4 is rotated again, so that the cross force teeth 15 in the force cavity 7 are misaligned with the cross groove structure 12, so that the cross force teeth 15 in the force cavity 7 cannot slide out of the force cavity 7;

[0054] The external ejection mechanism 26 continues to rise, the cross force teeth 15 slide in the force cavity 7, until the cross force teeth 15 contact the bottom of the pressure ring 2, the external ejection mechanism 26 continues to rise, and the force teeth 15 pass through the pressure ring 2 to eject the lower bead 1 and the solid tire 22 from the lower mold 23;

[0055] After the lower rim 1 and the solid tire 22 are ejected from the lower mold 23, the support is symmetrically placed between the solid tire 22 and the lower mold 23, and then the external ejection mechanism 26 makes the connecting rod 4 descend, and since the cross force tooth 15 is dislocated with the cross slot structure 12, when the cross force tooth 15 slides to the bottom end of the force receiving cavity 7, the cross force tooth 15 will not slide out of the cross slot structure 12, but will pull the force receiving cavity 7 to descend through the cross force tooth 15, and then make the cross force tooth 15 pull the lower rim 1 out of the solid tire 1 through the pressing ring 2, so as to realize the separation of the solid tire 1 and the lower rim 1.

[0056] After the solid tire 1 and the lower rim 1 are separated, the descending action of the external ejection mechanism 26 is paused, the connecting rod 4 is rotated through the rotating rod 18 to make the cross force tooth 15 in the force receiving cavity 7 align with the cross slot structure 12, the external ejection mechanism 26 continues to descend, and the cross force tooth 15 slides out of the force receiving cavity 7; finally, the pressing ring 2 and the force receiving ring 3 are removed from the lower rim 1.
