Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vulcanizing machine technology, specifically relating to a hydraulic vulcanizing machine. Background Technology
[0002] A vulcanizing machine is a machine used for vulcanizing various rubber and plastic materials. It has functions such as timed mold locking, automatic pressure compensation, automatic temperature control, automatic timing, and alarm when the time is up. There are many types of vulcanizing machines, and the wheel vulcanizing machine is one of them. The wheel vulcanizing machine is a processing equipment for shaping and vulcanizing raw tires, and it is also one of the essential pieces of equipment in the tire processing process. Because the main body of the vulcanizing machine is made of metal, it has high rigidity, and the parts are prone to plastic deformation, which affects the dimensional accuracy and normal use of the product. During vulcanization, the impact force generates vibration, which can easily lead to uneven stress on the tire during vulcanization, reducing the vulcanization effect. Therefore, a vulcanizing machine with good cushioning effect is needed for rubber tire production to solve the above problems. Utility Model Content

[0006] The pressure-bearing column has parallel inclined surfaces on both sides, and one side of the bottom of the pressure-bearing column is triangular, which matches the triangular gap formed by the inclined side of the main buffer plate and the inner wall of the cavity.

[0016] The hydraulic vulcanizing machine provided by this utility model will now be described in detail with reference to the accompanying drawings and an embodiment.
[0017] Example
[0018] Reference Figures 1-2This embodiment of a hydraulic vulcanizing machine includes an upper forming mold 6, an upper heat-conducting pressure plate 5, a frame side plate 3, a mold-locking and pressure-holding support rod 2, a top plate 1, a lower forming mold 7, a lower heat-conducting pressure plate 8, a support platform 10, and a base 11. The upper forming mold 6 is fixedly connected to the upper heat-conducting pressure plate 5 and is located inside the frame side plate 3. The upper heat-conducting pressure plate 5 is connected to the mold-locking and pressure-holding support rod 2. The mold-locking and pressure-holding support rod 2 is installed inside the frame side plate 3 via a connecting rod. The top of the mold-locking and pressure-holding support rod 2 is connected to the telescopic rod of a hydraulic cylinder. The lower forming mold 7 is fixedly connected to the lower heat-conducting pressure plate 8. The lower heat-conducting pressure plate 8 is installed on the support platform 10. The support platform 10 is installed on the base 11. The support platform 10 has a cavity 9. The bottom of the cavity 9 has a buffer plate. The bottom of the lower heat-conducting pressure plate 8 has a pressure-bearing column 13, which is located inside the cavity 9.
[0019] The cavity 9 is U-shaped, and the buffer plate includes a main buffer plate 14 and a secondary buffer plate 12. There is an inverted triangular gap between the main buffer plate 14 and the secondary buffer plate 12. The side of the main buffer plate 14 closest to the inner wall of the cavity is inclined.
[0020] The two sides of the pressure-bearing column 13 are parallel inclined surfaces, and one side of the bottom of the pressure-bearing column 3 is triangular and matches the triangular gap formed by the inclined side of the main buffer plate and the inner wall of the cavity.
[0021] The buffer plate is made of thermoplastic polyester material.
[0022] The frame side uprights 3 are provided with two plates, which are arranged opposite to each other.
[0023] The side plate 3 of the frame is provided with a guide slide rail 4. One end of the connecting rod is fixedly connected to the mold locking and pressure holding support rod 2, and the other end is fixedly connected to the slider. The slider moves up and down in cooperation with the guide slide rail.
[0024] The top plate 1 is fixed to the top of the side upright plate 3 of the frame. The top plate 1 is provided with a stamping guide sleeve 15, and the upper part of the mold locking and pressure holding support rod 2 is located inside the stamping guide sleeve 15.
[0025] During tire vulcanization, the pre-formed tire blank is first placed between the lower and upper forming molds of the vulcanizing machine. During operation, the tire blank is placed into the space of the lower forming mold. Then, under the action of the hydraulic cylinder at the top of the mold-locking and pressure-holding support rod, the telescopic rod moves downwards, causing the upper heat-conducting pressure plate, upper forming mold, and connecting rod to move downwards as a whole until the upper and lower forming molds are in complete contact. At this point, the tire blank is completely pressed into the intermediate cavity for vulcanization. During the overall movement of the upper forming mold, the slider on the connecting rod moves downwards along the guide rail. Guided by the guide rails on both sides of the machine frame side plate, the movement direction of the upper forming mold is limited to the vertical axis direction, ensuring smooth movement. When the upper forming mold presses down, it squeezes and impacts the tire in the mold cavity. The pressure-bearing column at the bottom can buffer the impact during the pressing through the buffer plate, reduce vibration, and stabilize the force. In addition, the two sides of the pressure-bearing column are parallel inclined surfaces, and one side of the bottom of the pressure-bearing column is triangular. In conjunction with the inclined side of the main buffer plate, the pressure-bearing column slides along the inclined surface, which is more stable and further improves the buffering effect and the tire vulcanization effect.
