Description

Technical Field

[0001] This utility model relates to the field of tire vulcanizing equipment, specifically a connecting device for a vulcanizing machine between a movable mold and a water cylinder. Background Technology

[0002] As is well known, the sliding mold and hydraulic cylinder of the vulcanizing machine are set vertically, which has the following problems: the hydraulic cylinder seals are prone to wear and the piston rod is corroded by the motive water, causing seal failure and resulting in water leakage into the sliding mold; the motive water corrodes the piston rod, resulting in poor drainage. Usually, after repairing the sliding mold leakage, the water in the vulcanizing machine chamber needs to be manually pumped out. Moreover, when the sliding mold leaks during production, the water directly enters the vulcanizing chamber, affecting the internal temperature during the vulcanizing process, resulting in defective products such as large temperature differences and incomplete vulcanization. To solve the leakage problem, the method of adding sealing rings or optimizing materials is generally adopted, but ultimately it cannot solve the impact of sliding mold leakage on quality. Summary of the Invention

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a connecting device for a vulcanizing machine and a water tank, which physically blocks the path of water droplets leaking into the vulcanizing machine.

[0004] The technical solution adopted by this utility model to solve its technical problem is: a connecting device for a vulcanizing machine and a water cylinder, comprising a vulcanizing machine housing, a connecting mold installed below the vulcanizing machine housing, and a hydraulic water cylinder installed above the vulcanizing machine housing. The connecting mold and the hydraulic water cylinder are installed in a staggered manner. The cylinder rod of the hydraulic water cylinder is fixed to the upper end of a connecting shaft via a coupling. The connecting mold is fixedly connected to the lower end of a second connecting rod via a connecting mold flange. The upper end of the second connecting rod is connected to the end of a first connecting rod via a right universal hinge. The other end of the first connecting rod is connected to the lower end of the connecting shaft via a left universal hinge. A guide groove with an inclination angle of 45 degrees is connected to the lower part of the connecting shaft. The lower end of the guide groove is located at the upper opening of a water collection box. A liquid level sensor is installed inside the water collection box. A photoelectric sensor is installed on the side of the second connecting rod. The liquid level sensor and the photoelectric sensor are connected to the signal input terminal of a PLC controller. The signal output terminal of the PLC controller controls the operation of the liquid level alarm and the hydraulic water cylinder.

[0005] The beneficial effects of this invention are that it blocks the path of water droplets to the movable mold, completely avoids liquid contact with the movable mold, and has a simple structure with low maintenance and repair difficulty. Attached Figure Description

[0006] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0007] Figure 1 This is a schematic diagram of the structure of the present invention.

[0008] In the diagram: 1. Hydraulic cylinder, 2. Vulcanizing machine housing, 3. Coupling, 4. Photoelectric sensor connecting frame, 5. Shaft, 6. Water collection box, 7. Flexible mold, 8. Connecting rod one, 9. Right universal hinge, 10. Connecting rod two, 11. Left universal hinge. Detailed Implementation

[0009] In the figure, this utility model includes a vulcanizing machine housing 2, a movable mold 7 installed below the vulcanizing machine housing 2, and a hydraulic cylinder 1 installed above the vulcanizing machine housing 2. The movable mold 7 and the hydraulic cylinder 1 are installed in a staggered manner. The cylinder rod of the hydraulic cylinder 1 is fixed to the upper end of the connecting shaft 5 via a coupling 3. The movable mold 7 is fixedly connected to the lower end of the connecting rod 10 via a movable mold flange. The upper end of the connecting rod 10 is connected to the end of the connecting rod 8 via a right universal hinge 9. The other end of the connecting rod 8 is connected to the lower end of the connecting shaft 5 via a left universal hinge 11. An inclined [device] is connected to the lower part of the connecting shaft 5. A 45-degree angle guide channel is provided, with its lower end located at the upper opening of the water collection box 6. A liquid level sensor is installed inside the water collection box 6, which is fixed to the vulcanizing machine housing 2. A photoelectric sensor connecting frame 4 is provided parallel to one side of the connecting rod 2 10. A photoelectric sensor is installed on the photoelectric sensor connecting frame 4, which is fixed inside the vulcanizing machine housing 2. The liquid level sensor and the photoelectric sensor are connected to the signal input terminal of the PLC controller. The signal output terminal of the PLC controller controls the liquid level alarm and the hydraulic cylinder 1.

[0010] When water enters the rodless chamber and drains from the rod chamber of hydraulic cylinder 1, the hydraulic rod extends and drives the connecting shaft 5 to move vertically downwards via coupling 3. Connecting rod 8 and connecting rod 10 adjust their angles via left universal hinge 11 and right universal hinge 9. As connecting shaft 5 is pressed down, connecting rod 10 is also pressed down, causing the movable mold to extend. When it reaches the photoelectric sensor position, hydraulic cylinder 1 stops extending. Conversely, when water enters the rod chamber and drains from the rodless chamber of hydraulic cylinder 1, the hydraulic rod retracts and drives the connecting shaft 5 to move vertically upwards via coupling 3. This, in turn, drives the movable mold to retract via connecting rod 8 and connecting rod 10. When it retracts to the photoelectric sensor position, hydraulic cylinder 1 stops retracting.

[0011] When hydraulic cylinder 1 leaks, the power water will flow downwards along the outer surface of the connecting shaft 5 under gravity, eventually converging in the guide groove at the bottom of the connecting shaft 5. The lower end is connected to the water collection box 6 to ensure that the liquid is collected in a specific direction. The leaked liquid will not enter the movable mold 7 with the shaft and will not affect the movable mold due to the leakage of hydraulic cylinder 1. A liquid level sensor is installed inside the water collection box 6 to detect the water level. When the water level reaches the set height, the liquid level sensor transmits a signal to the PLC controller. The PLC controller controls the liquid level alarm to sound an alarm to prevent the water level in the water collection box 6 from overflowing due to excessive water level.

[0012] This invention uses an N-shaped linkage mechanism to separate the connecting shaft between the movable mold 7 and the hydraulic cylinder 1, physically blocking the path of water droplets leaking into the movable mold. Simultaneously, the guide channel and water collection box provide double protection, completely preventing liquid from contacting the movable mold. It boasts strong compatibility and is applicable to various occasions. During vulcanizing machine installation, there is no need to modify the original cylinder body; it can be independently installed on existing vulcanizing machines. Furthermore, its simple structure and low maintenance and repair difficulty make it easy to implement.
