[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] like Figures 1 to 4 As shown, the utility model provides a vacuum cover guide mechanism 100 of a vacuum vulcanization molding machine, comprising an upper seat 1, a vacuum cover assembly 2, at least one vacuum oil cylinder 3, at least two guide rods 4 and at least two guide flanges 5. The vacuum cover assembly 2 is fixedly installed below the upper seat 1. The connection between the vacuum cover assembly 2 and the upper seat 1 forms a closed space inside the vacuum cover assembly 2. The closed space is used to vacuum the mold. The vacuum oil cylinder 3 vertically passes through the upper seat 1 and is connected to the vacuum cover assembly 2 to drive the vacuum cover assembly 2. Figures 9-10As shown, the two guide flanges 5 are symmetrically arranged below the upper seat 1, and the lower ends of the two guide rods 4 vertically pass through the upper seat 1 and the two guide flanges 5 in sequence and are symmetrically connected to the vacuum cover assembly 2. Since the guide rods 4 vertically pass through the upper seat 1, that is, the guide rods 4 are parallel to each other, the guide rods 4 can limit the movement of the vacuum cover assembly 2 below the upper seat 1 in the vertical direction during the driving operation of the vacuum cylinder 3; therefore, during the rising or falling process of the vacuum cover assembly 2 of the vacuum vulcanization molding machine, under the guiding action of the guide rods 4, the vacuum cover assembly 2 runs smoothly, which reduces the mutual wear of the internal components of the vacuum cover assembly 2 to a certain extent and extends the service life of the internal sealing ring of the vacuum cover assembly 2, further saving the time and maintenance cost of replacing equipment.

[0028] Preferably, if Figures 5-7 As shown, the vacuum cover assembly 2 of this embodiment includes a vacuum cover 21 and a vacuum axis 22. The vacuum axis 22 is arranged inside the vacuum cover 21. The upper end surface of the vacuum cover 21 is connected to the upper seat 1. The vacuum axis 22 is connected to the lower end surface of the vacuum cover 21. The upper end surface of the vacuum cover 21 is provided with at least one first screw hole. The vacuum cover 21 is screwed into the first screw hole and fixed, so that the vacuum cover 21 is assembled to the lower end of the upper seat 1.

In the process of the vacuum cylinder 3 pushing the vacuum cover 21 to move up or down, the vacuum cover 21 is symmetrically limited by at least two guide rods 4, and is symmetrically fixed to the upper end surface of the vacuum cover 21 through more than two guide rods 4. In the process of pushing the vacuum cylinder 3, the vacuum cover 21 is limited by the two guide rods 4 to move in the vertical direction, reducing the horizontal deviation and avoiding the collision or friction between the inner wall of the vacuum cover 21 and the vacuum axis 22 to a certain extent.

[0030] Preferably, two vacuum cylinders 3 are included, and the two vacuum cylinders 3 pass through the upper seat 1 to be symmetrically connected to both sides of the vacuum cover 21. The two vacuum cylinders 3 can more easily push the vacuum cover 21 up and down.

[0031] Preferably, four guide rods 4 are included, and the four guide rods 4 pass through the upper seat 1 to be symmetrically connected at opposite corners of the vacuum cover 21. During the lifting or lowering movement of the vacuum cover 21 pushed by the vacuum oil cylinder 3, the vacuum cover 21 is limited in the vertical direction by the four guide rods 4, and is symmetrically fixed to the upper end surface of the vacuum cover 21 by the four guide rods 4. During the pushing process of the vacuum oil cylinder 3, the vacuum cover 21 is limited in the vertical direction by the four guide rods 4, reducing the horizontal deviation, and the horizontal limiting effect of the four guide rods 4 on the vacuum cover 21 is more stable and reliable.

[0032] Preferably, the embodiment includes four guide flanges 5, and the four guide flanges 5 are arranged below the upper seat 1. The lower ends of the four guide rods 4 pass through the upper seat 1 and the four guide flanges 5 in sequence and are symmetrically connected to the vacuum cover 21. The guide rod 4 is vertically fixed to the side of the vacuum cover 21 through the upper seat 1 and the guide flange 5, and the horizontal limiting effect of the guide rod 4 on the vacuum cover 21 is more stable and reliable, achieving the horizontal lifting and lowering of the vacuum cover 21 in front, back, left and right.

[0033] Preferably, the side of the vacuum cover 21 is also provided with an ear 211, and the guide rod 4 is fixed to the ear 211. The guide rod 4 is vertically fixed to the ear 211 of the vacuum cover 21 through the upper seat 1 and the guide flange 5. The ear 211 of the vacuum cover 21 is provided with at least two second threaded holes 212, and the guide rod 4 is screwed into the second threaded hole 212 for connection and fixation, so that the guide rod 4 is fixed to the vacuum cover 21.

[0034] Preferably, the guide flange 5 is embedded with a bearing, and the guide flange 5 can move up and down freely in the bearing. Specifically, the guide flange 5 rises or falls with the vacuum cover 21 under the guidance of the bearing.

[0035] Preferably, the bearing is an oil-free bearing, which better lubricates the guide flange 5 and makes the vacuum cover 21 run more smoothly and smoothly.

[0036] Preferably, the upper seat 1 is provided with a through hole 11, and the guide rod 4 passes through the through hole 11 of the upper seat 1 and is symmetrically connected to the vacuum cover assembly 2. During the lifting or lowering process of the vacuum cover 21, the guide rod 4 moves up and down in the through hole 11 of the upper seat 1.

[0037] In summary, the present invention provides a vacuum hood guide mechanism for a vacuum vulcanizing molding machine, comprising an upper seat, a vacuum hood assembly, at least one vacuum oil cylinder, and at least two guide rods.
