Description

Technical Field

[0001] This utility model relates to the field of capsule vulcanizing machine technology, specifically to a novel opening and closing mold device for a multi-layer capsule vulcanizing machine. Background Technology

[0002] A bladder vulcanizing machine, which uses a molding method to manufacture bladders for tire shaping and vulcanizing, mainly consists of a main hydraulic cylinder, an upper core mold cylinder, a lower core mold cylinder, an upper crossbeam, wall plates, and an oil circuit system. Chinese Patent Publication No. CN107053718B discloses a tire vulcanizing machine, including: a column; a top plate disposed at the top of the column; a bottom plate disposed at the bottom of the column; a lifting mechanism disposed on the top plate; and several layers of opening and closing mold mechanisms, sequentially connected and slidably arranged along the column direction. The opening and closing mold mechanisms at the top are connected to the lifting mechanism, and the opening and closing mold mechanisms at the bottom are mounted on the bottom plate.

[0003] Regarding the disclosed technology, the current capsule vulcanizing machine on the market uses a hydraulic cylinder mounted on the crossbeam of the vulcanizing machine to open and close the mold. The piston rod of the hydraulic cylinder extends and retracts to open and close the mold. However, since the hydraulic cylinder is mounted above the crossbeam and the piston rod passes through the crossbeam, and the cylinder body is fixed upwards on the upper crossbeam, the overall height of the vulcanizing machine is very high, especially for multi-layer capsule vulcanizing machines, where the overall height is basically over 6 meters. This places high demands on the height of the workshop when installing the vulcanizing machine, especially for some low-ceilinged production workshops, which require raising the workshop roof, thus increasing the operating cost.

[0004] To address this, a novel opening and closing mold device for a multi-layer capsule vulcanizing machine is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the problem that the opening and closing mold of the capsule vulcanizing machine currently on the market is to install a hydraulic cylinder on the crossbeam of the vulcanizing machine and open and close the mold by extending and retracting the piston rod of the hydraulic cylinder. However, since the hydraulic cylinder is installed above the crossbeam, the overall height of the vulcanizing machine is very high, which requires a high height in the workshop when installing the vulcanizing machine. This utility model provides a new type of opening and closing mold device for multi-layer capsule vulcanizing machines.

[0006] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0007] A novel opening and closing mold device for a multi-layer capsule vulcanizing machine includes a base, a column fixedly connected to the top surface of the base, two sets of lifting components for mold lifting and lowering provided on the surface of the base, a pressure plate fixedly connected to the surface of the lifting components, a guide component provided on the surface of the pressure plate, a mold connecting component for mold lifting and lowering provided on the surface of the guide component, a mold component provided on the surface of the guide component and the surface of the mold connecting component, an upper crossbeam fixedly connected to the top surface of the column, a sliding component for cooperating with the movement of the mold connecting component provided on the surface of the column, and a first slider base fixedly connected to the surface of the mold component and the surface of the sliding component.

[0008] Furthermore, the lifting assembly includes a connecting seat, the surface of the base is fixedly connected to the connecting seat, the top surface of the connecting seat is provided with a hydraulic cylinder device, and there are two hydraulic cylinder devices in a set, and the two hydraulic cylinder devices are obliquely symmetrically distributed on the surface of the base through the connecting seat. The output end of the hydraulic cylinder device is fixedly connected to a connecting piece, and the pressure plate is fixedly connected to the connecting piece.

[0009] Furthermore, the guide assembly includes a guide rod, the guide rod is movably inserted into the surface of the pressure plate, and three lifting blocks are fixedly sleeved on the surface of one of the guide rods.

[0010] Furthermore, the mold connecting assembly includes a first ring structure, the guide rod surface is slidably connected to the first ring structure, and the guide rod surface is slidably connected to the second ring structure.

[0011] Furthermore, the mold assembly includes a primary vulcanizing platform structure. The primary vulcanizing platform structure is fixedly connected to the surface of the first collar structure, and the primary vulcanizing platform structure is slidably connected to the guide rod through the first collar structure. The first slider base is fixedly connected to the primary vulcanizing platform structure by bolts. The secondary vulcanizing platform structure is fixedly connected to the surface of the second collar structure, and the secondary vulcanizing platform structure is slidably connected to the guide rod through the second collar structure. The second slider base is fixedly connected to the secondary vulcanizing platform structure by bolts. The surface of the base is provided with a tertiary vulcanizing platform structure.

[0012] Furthermore, the sliding assembly includes a slide rail, the surface of the column is fixedly connected to the slide rail, the surface of the slide rail is slidably connected to a slider, and a first slider base is fixedly connected to a set of sliders, and a second slider base is fixedly connected to a set of sliders.

[0013] The beneficial effects of this utility model are as follows:

[0014] This utility model features a set of lifting components with two symmetrically arranged hydraulic cylinders. During mold opening, the hydraulic cylinders drive the pressure plate upward. As the pressure plate moves upward, the guide rod, through a lifting block, moves the mold connecting component. The first moving seat, via the lifting block, first moves the primary vulcanizing platform structure upward. After moving a certain distance, the middle lifting block engages with the second ring structure, and the second moving seat then moves the secondary vulcanizing platform structure upward. Simultaneously, the primary and secondary vulcanizing platform structures are slidably connected to the guide rod, which allows the guide rod to engage with the primary and secondary vulcanizing platform structures. The device guides the movement of the mold assembly, and the sliding components, in conjunction with the movement of the mold connecting components, drive the primary, secondary, and tertiary vulcanizing platform structures to open the mold. After the movement is complete, the primary and secondary vulcanizing platform structures are moved back to their original positions, thus completing the opening and closing of the mold assembly. The device places the mold opening and closing lifting components on the base. The extension of the piston rod of the lifting components opens the mold, and the retraction of the piston rod closes the mold. This achieves both mold opening and closing and reduces the overall height of the machine, thereby lowering the requirements for factory height. Attached Figure Description

[0026] like Figure 1-6As shown, a novel multi-layer capsule vulcanizing machine opening and closing mold device includes a base 1, a column 2 fixedly connected to the top surface of the base 1, two sets of lifting components 3 for mold lifting and lowering are provided on the surface of the base 1, a pressure plate 4 is fixedly connected to the surface of the lifting components 3, a guide component 5 is provided on the surface of the pressure plate 4, a mold connecting component 6 for mold lifting and lowering is provided on the surface of the guide component 5, a mold component 7 is provided on the surface of the guide component 5 and the surface of the mold connecting component 6, an upper crossbeam 8 is fixedly connected to the top surface of the column 2, a sliding component 9 for cooperating with the movement of the mold connecting component 6 is provided on the surface of the column 2, a first slider base 10 is fixedly connected to the surface of the mold component 7 and the surface of the sliding component 9, and a second slider base 11 is fixedly connected to the surface of the mold component 7 and the surface of the sliding component 9; specifically, in this novel multi-layer capsule vulcanizing machine opening and closing mold device, the lifting components 3 are mounted on the base 1, located at... Outside the base 1, during tire processing, the lifting assembly 3 moves the guide assembly 5 via the pressure plate 4. When the pressure plate 4 moves upward, there is a limiting structure between the pressure plate 4 and the guide assembly 5, which in turn can drive the guide assembly 5 to move upward. During the movement of the guide assembly 5, due to the mold connecting assembly 6 between the guide assembly 5 and the mold assembly 7, the mold connecting assembly 6 can drive the mold assembly 7 to move. Conversely, the lifting assembly 3 can also drive the mold assembly 7 back to its original position, allowing the mold assembly 7 to open and close. The sliding assembly 9 assists in the movement of the mold connecting assembly 6. This device sets the lifting assembly 3 for opening and closing the mold on the base 1. The extension of the piston rod of the lifting assembly 3 opens the mold, and the retraction of the piston rod closes the mold. This achieves both mold opening and closing and reduces the overall height of the machine, thereby reducing the requirements for factory height.

[0027] like Figure 1 , Figure 3 , Figure 4 As shown, the lifting assembly 3 includes a connecting seat 301. The connecting seat 301 is fixedly connected to the surface of the base 1. A hydraulic cylinder device 302 is provided on the top surface of the connecting seat 301. There are two hydraulic cylinder devices 302 in a set, and the two hydraulic cylinder devices 302 are obliquely symmetrically distributed on the surface of the base 1 through the connecting seat 301. The output end of the hydraulic cylinder device 302 is fixedly connected to a connecting member 303, and the pressure plate 4 is fixedly connected to the connecting member 303. Specifically, the lifting assembly 3 is set on the base 1 and located outside the base 1. The connecting seat 301 is installed outside the base 1 and is connected to the hydraulic cylinder device 302. The two hydraulic cylinder devices 302 in a set are symmetrically distributed at 45°. When the hydraulic cylinder device 302 is running, the output end of the hydraulic cylinder device 302 drives the pressure plate 4 to move upward, so that the pressure plate 4 can move upward stably.

[0028] like Figure 5As shown, the guide assembly 5 includes a guide rod 501. The guide rod 501 is movably inserted into the surface of the pressure plate 4. Three lifting blocks 502 are fixedly sleeved on the surface of one guide rod 501, and the three lifting blocks 502 are located at the top, middle and bottom of the guide rod 501, respectively. Specifically, when the pressure plate 4 moves upward, the top surface of the pressure plate 4 will first come into contact with the lifting block 502 through the setting of the guide assembly 5. Through the limiting of the lifting block 502, the guide rod 501 is driven to move upward. When the guide rod 501 moves upward, the guide rod 501 drives the mold connecting assembly 6 to move through the lifting block 502, which cooperates with the mold opening process of the mold assembly 7.

[0029] like Figure 2 , Figure 5 , Figure 6 As shown, the mold connecting assembly 6 includes a first ring structure 601, a guide rod 501 with the first ring structure 601 slidably connected to the surface of the guide rod 501, and a second ring structure 602 slidably connected to the surface of the guide rod 501. Specifically, in the mold connecting assembly 6, the first ring structure 601 and the second ring structure 602 are slidably connected to the guide rod 501. When the guide rod 501 moves, it first engages with the first ring structure 601 through the middle lifting block 502, causing the first ring structure 601 to move. The first ring structure 601 first causes the components of the mold assembly 7 to move. After moving a certain distance, the second ring structure 602, driven by the bottom lifting block 502, can then continue to drive the other component of the mold assembly 7 to move.

[0030] like Figure 1 , Figure 2As shown, the mold assembly 7 includes a primary vulcanizing platform structure 701. The primary vulcanizing platform structure 701 is fixedly connected to the surface of a first collar structure 601, and is slidably connected to a guide rod 501 via the first collar structure 601. The first slider base 10 is fixedly connected to the primary vulcanizing platform structure 701 via bolts. A secondary vulcanizing platform structure 702 is fixedly connected to the surface of a second collar structure 602, and is slidably connected to the guide rod 501 via the second collar structure 602. The second slider base 11 is fixedly connected to the secondary vulcanizing platform structure 702 via bolts. A tertiary vulcanizing platform structure 703 is provided on the surface of the base 1. Specifically, the primary vulcanizing platform structure 701 consists of an upper mold platen at the bottom of the pressure plate 4 and the upper part of the primary vulcanizing platform structure 701. The secondary vulcanizing platform structure 702 is composed of the upper mold plate at the bottom of the primary vulcanizing platform structure 701 and the lower mold plate on the secondary vulcanizing platform structure 702. The tertiary vulcanizing platform structure 703 is composed of the upper mold plate at the bottom of the secondary vulcanizing platform structure 702 and the lower mold plate on the tertiary vulcanizing platform structure 703. When the mold is opened, the first ring structure 601 is fixedly connected to the primary vulcanizing platform structure 701. The lifting block 502 first comes into contact with the first ring structure 601. Driven by the lifting block 502, the first ring structure 601 will first drive the primary vulcanizing platform structure 701 to move upward. Then the bottom lifting block 502 comes into contact with the second ring structure 602, driving the second ring structure 602 to move, which in turn will drive the secondary vulcanizing platform structure 702 to move upward.

[0031] like Figure 2 , Figure 5 As shown, the sliding assembly 9 includes a slide rail 901. The slide rail 901 is fixedly connected to the surface of the column 2, and a slider 902 is slidably connected to the surface of the slide rail 901. The first slider base 10 is fixedly connected to a set of sliders 902, and the second slider base 11 is fixedly connected to a set of sliders 902. Specifically, the sliding assembly 9 is configured such that the slide rail 901 is mounted on the column 2, the first slider base 10 in the middle is fixedly connected to the primary vulcanizing platform structure 701, and the second slider base 11 at the bottom is fixedly connected to the secondary vulcanizing platform structure 702. When the first ring structure 601 and the second ring structure 602 move, the slider 902 slides on the slide rail 901. Therefore, it can guide the movement of the mold assembly 7 in conjunction with the movement of the mold assembly 7.

[0032] In summary: This novel multi-layer capsule vulcanizing machine uses an opening and closing mold device. The lifting component 3 is mounted on the base 1. The output end of the hydraulic cylinder 302 drives the pressure plate 4 to move upward. When the pressure plate 4 moves upward, the top surface of the pressure plate 4 first comes into contact with the top lifting block 502 through the guide component 5. The top lifting block 502 limits the movement of the guide rod 501. When the guide rod 501 moves upward, it drives the mold connecting component 6 to move through the lifting block 502. When the mold connecting component 6 moves, the middle lifting block 502 first comes into contact with the first ring structure 601. Then, the first ring structure 601 first drives the first-stage vulcanizing platform structure 701 to move upward. After moving a certain distance, the bottom lifting block 502 comes into contact with the second ring structure 602. The ring structure 602 drives the secondary vulcanizing platform structure 702 to move upward. The sliding component 9 is set up with the slide rail 901 installed on the column 2. The first slider base 10 is fixedly connected to the slider 902, and the first slider base 10 is also fixedly connected to another set of sliders 902. When the mold assembly 7 moves, the slider 902 slides on the slide rail 901. Therefore, it can guide the movement of the mold assembly 7. At this time, the primary vulcanizing platform structure 701, the secondary vulcanizing platform structure 702 and the tertiary vulcanizing platform structure 703 can be driven to open the mold. After the movement is completed and the tire blank is placed, the output end of the hydraulic cylinder device 302 drives the pressure plate 4 to move downward. Conversely, it drives the primary vulcanizing platform structure 701 and the secondary vulcanizing platform structure 702 back to their original positions, thus completing the opening and closing of the mold assembly 7.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
