Description

Technical Field

[0001] This utility model relates to a vulcanizing component of a tire shaping vulcanizing machine, specifically a hot plate that can be quickly connected to a mold vacuum system. Background Technology

[0002] In recent years, rubber equipment companies have been seeking new technologies and processes to enhance their competitiveness.

[0003] Many mold manufacturing companies are actively innovating their technology and have added a vacuum function to new tire molds. During tire vulcanization, there will be air between the mold and the tire that affects the tire quality. The vacuum function is mainly to remove this air from the mold, so that the tires produced have better performance.

[0004] In order for the new tire molds to function better, the tire vulcanizing machine also needs to be continuously innovated and connected with the mold vacuuming. The existing connection method is to screw the threaded connector of the metal hose onto the mold evacuation hole. Every time the mold is changed, the connector must be unscrewed first, and after the new mold is installed, the connector of the metal hose must be screwed back onto the new mold. The process is cumbersome, time-consuming and labor-intensive, which affects the tire production efficiency. Utility Model Content

[0005] To address the problem of difficulty in connecting vacuum pipes when changing molds in existing technologies, this utility model proposes a hot plate that can be quickly connected to the mold vacuum system.

[0006] A hot plate capable of quickly connecting to a mold vacuum system, which solves the problems of existing technologies, includes a heating plate body mounted on a heat insulation plate, the heat insulation plate mounted on a lower support plate, and the mold mounted on the heating plate body. The difference lies in:

[0007] 1. Corresponding to the air extraction hole at the bottom of the mold, a vent hole is provided on the heating plate. A sealing component is provided between the mold and the heating plate where the vent hole and the air extraction hole connect.

[0008] 2. Corresponding to the vent, through holes I and II are respectively provided on the heat insulation plate and the lower support plate.

[0009] 3. A rigid air tube is inserted through through hole I and through hole II. The upper end of the rigid air tube is connected to the bottom of the vent hole with a threaded structure, and the lower end of the rigid air tube is connected to the vacuum pipe through a flexible tube.

[0010] The beneficial effects of this utility model are:

[0011] This utility model features a vent hole on the hot plate of a mold vacuum system that allows for quick connection to the vacuum pipe. This vent hole connects to the vacuum pipe of the mold, enabling quick connection of the mold's vacuum pipe to the vacuum pipe when changing molds. This eliminates the tedious work of disassembling and assembling pipe joints when changing molds, thus improving work efficiency. Attached Figure Description

[0015] The technical solution of this utility model will be further described below with reference to the embodiments shown in the accompanying drawings.

[0016] This utility model relates to a heating plate for quickly connecting a mold vacuum system. It includes a heating plate body 1 as the main body, which is mounted on a heat insulation plate 2 via a pad 5. The heat insulation plate 2 is mounted on a lower support plate 3, which is installed at the bottom of a steamer 11. A mold 4 is placed inside the steamer 11 and mounted on the heating plate body 1 (the bottom surface of the mold 4 is tightly attached to the top surface of the heating plate body 1 and secured with bolts). Figure 1 As shown.

[0017] A vertical air extraction hole 4-1 (connecting to the interior of the mold 4) is provided on one side of the bottom of the mold 4, such as... Figure 2 As shown.

[0018] A ventilation hole 1-1 (vertically penetrating the plate body) is provided on the heating plate body 1, corresponding to the exhaust hole 4-1. A sealing assembly is provided between the mold 4 and the heating plate body 1 at the connection between the ventilation hole 1-1 and the exhaust hole 4-1. The sealing assembly includes an inner ring and an outer ring seal. The outer ring seal is an O-ring 9, and the inner ring seal is a graphite wound gasket 10. Each seal is located in a corresponding sealing groove on the heating plate body 1. Figure 2 As shown.

[0019] The vent 1-1 is aligned with the gasket 5, the heat insulation plate 2, and the lower support plate 3, which are respectively provided with vertically connected through holes, through hole I and through hole II, as shown in the example. Figure 2 As shown.

[0020] Ventilation vent 1-1 is provided at the bottom of the steamer 11, such as... Figure 1 As shown.

[0021] A rigid air pipe 6 extends upwards from the bottom of the steamer 11, passing sequentially through the lower support plate 3, the heat insulation plate 2, and the pad 5. The upper end of the rigid air pipe 6 has a tapered external thread that screws into the tapered internal thread at the bottom of the vent hole 1-1. The lower end of the rigid air pipe 6 is connected to a vacuum pipe 8 via a flexible hose 7, thereby extracting air from the mold 4. Figure 1 , Figure 2 As shown.

[0022] The operating mode of this utility model is as follows:

[0023] When it is necessary to replace mold 4, open steamer 11 to remove mold 4, and then replace it with a new mold 4. The O-ring 9 and graphite spiral wound gasket 10 are pressed together by the weight of mold 4 itself and the tension of the fixing bolts, thus forming a sealed vacuum system without the need for additional disassembly and assembly work.
