Description

TECHNICAL FIELD

[0001] The utility model relates to the component structure of tire setting curing press, concretely is a hydraulic curing press steamer combined formula lower backplate. BACKGROUND

[0002] The hydraulic curing press is more and more high in market share because the force is more uniform, and the quality of vulcanized tire is better. Of course, the hydraulic curing press also has some deficiencies, and the maintenance of the force cylinder is the most headache thing for the maintenance personnel. Although the upper force cylinder has larger dismounting space than the previous lower force cylinder, but is limited by the traditional integral lower backplate structure, when the force cylinder needs to be maintained, the lower backplate must be hoisted out integrally, and to dismount the lower backplate, the center mechanism and the pipeline associated with the center mechanism must be dismounted first, which invisibly greatly increases the maintenance workload of the force cylinder and the labor intensity of the maintenance personnel. CONTENT OF THE UTILITY MODEL

[0003] In view of the deficiency of the prior art, the utility model provides a hydraulic curing press steamer combined formula lower backplate, overcomes the problem of difficult dismounting of the force cylinder under the traditional integral lower backplate structure, and makes the maintenance work of the force cylinder and the center mechanism can be independently carried out, thereby greatly reducing the maintenance workload and labor intensity.

[0004] The utility model realizes the above-mentioned purpose through the following technical scheme:

[0005] The hydraulic curing press steamer combined formula lower backplate is composed of an inner ring and an outer ring, the inner ring is sleeved on the center mechanism for installation of the center mechanism, the outer ring is supported by the force cylinder and is sleeved outside the inner ring for bearing the closing force of the force cylinder, the inner ring and the outer ring are connected through a connecting flange with screws, and a groove is formed in the inner side of the outer ring for installation of a sealing assembly I between the inner ring.

[0006] Further, a groove is formed in the outer side of the outer ring for installation of a sealing assembly II between the lower steamer.

[0007] Further, a stepped through hole is formed in the middle of the outer ring for connecting the force cylinder and installing a sealing assembly III.

[0008] Further, the sealing assembly I is formed by stacking a plurality of V-shaped sealing rings.

[0009] Further, the sealing assembly II comprises a pressing plate, a stud, a nut and a sealing ring.

[0010] Further, the sealing assembly III comprises a gland, a sealing gasket and a bolt.

[0011] Compared with the prior art, the utility model has the following advantages and effects:

[0012] 1. The traditional integral lower platen is split into independent inner ring and outer ring, so that the maintenance of force cylinder and center mechanism can be carried out independently, that is, when the force cylinder needs to be maintained, only the outer ring needs to be disassembled, when the center mechanism needs to be maintained, only the inner ring needs to be disassembled, which does not affect each other, greatly simplifies the disassembly steps, and greatly reduces the workload and labor intensity of the maintenance personnel.

[0013] 2. The sealing assembly between the inner ring and the outer ring of the combined lower platen is arranged in the groove on the inner side of the outer ring, which is easier to install and replace. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0017] The utility model will be further described below in combination with embodiments, but the utility model is not limited to these embodiments.

[0018] The combined lower platen of the hydraulic curing machine boiler in the embodiment is composed of an inner ring 1 and an outer ring 2, wherein the inner ring 1 is sleeved on the center mechanism 3 for installation of the center mechanism 3, the outer ring 2 is supported by the force cylinder 4 and is sleeved outside the inner ring 1 for bearing the mold closing force of the force cylinder 4, the inner ring 1 and the outer ring 2 are connected by the connecting flange 5 and the screw 6, the inner side upper edge of the outer ring 2 is provided with a groove for installation of the sealing assembly I between the inner ring 1, so as to prevent steam leakage on the combined lower platen, and the sealing assembly I in the embodiment is composed of a plurality of V-shaped sealing rings 7. Figure 1 As shown in the figure, the center mechanism is installed on the inner ring 1 of the combined lower platen, the force cylinder 4 is fixed on the counterbore of the lower boiler 8 through the fastening screw 17, the piston rod of the force cylinder 4 is connected with the outer ring 2 of the combined lower platen through the connecting screw 16, the outer ring 2 is provided with a stepped through hole for installation of the connecting screw 16 and the sealing assembly III in the middle part, the sealing assembly III includes the gland 13, the sealing gasket 14 and the bolt 15, the gland 13 and the sealing gasket 14 are pressed tightly through the bolt 15, so as to prevent steam on the lower platen from leaking from the hole.

[0019] Figure 2 As shown in the figure, the center mechanism is installed on the inner ring 1 of the combined lower platen, the force cylinder 4 is fixed on the counterbore of the lower boiler 8 through the fastening screw 17, the piston rod of the force cylinder 4 is connected with the outer ring 2 of the combined lower platen through the connecting screw 16, the outer ring 2 is provided with a stepped through hole for installation of the connecting screw 16 and the sealing assembly III in the middle part, the sealing assembly III includes the gland 13, the sealing gasket 14 and the bolt 15, the gland 13 and the sealing gasket 14 are pressed tightly through the bolt 15, so as to prevent steam on the lower platen from leaking from the hole.
