[0001] This utility model relates to the technical field of rubber product processing equipment, specifically to a vulcanization device for producing rubber sealing rings. Background Technology

[0002] In modern industry, rubber seals, as core components for sealing and protection, are widely used in the automotive, aerospace, and machinery industries. As the manufacturing sector continues to demand higher sealing performance, the vulcanization process and equipment technology for rubber seals are constantly evolving.

[0003] Traditional single-station vulcanizing units, operating sequentially through a single loading, vulcanization, and demolding process, can meet basic production needs, but suffer from significant efficiency bottlenecks: First, the equipment operates under continuous high temperature and pressure during vulcanization, while non-vulcanization steps such as loading and demolding consume considerable time, leading to energy waste and idle capacity; second, each unit can only process a single product, making it difficult to meet the efficiency demands of large-scale production, especially when switching between multiple product specifications, further extending the equipment's idle time. Therefore, there is an urgent need to design a vulcanizing unit for rubber sealing ring production to address these issues. Utility Model Content

Detailed Implementation

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-4 As shown in the figure, the vulcanizing device for producing rubber sealing rings provided in this embodiment of the utility model includes a plate body 1, a driving assembly 2 is provided on the top of the plate body 1, and a plurality of mold assemblies 3 are threadedly connected to the top of the driving assembly 2. The driving assembly 2 is used to move the mold assemblies 3 at least. A base box 7 is bolted to the bottom of the plate body 1, and an extrusion assembly 4 is fixedly connected to the top of the base box 7. The mold assemblies 3 are used to extrude the mold assemblies 3 at least. A lifting assembly 5 is provided on one side of the base box 7. The lifting assembly 5 is used to lift the mold assemblies 3 at least.

[0027] In this embodiment, a plate body 1 is included, and a driving component 2 is provided on the top of the plate body 1. A plurality of mold components 3 are threadedly connected to the top of the driving component 2. The driving component 2 is used at least for moving the mold components 3.

[0028] Specifically, the drive assembly 2 includes a fixing plate 21 bolted to the top of the plate 1. It is fixedly connected to the top plane of the plate 1 by M12 high-strength bolts to ensure connection rigidity. The top of the fixing plate 21 is bolted to a drive motor 22, and its output shaft is connected to the keyway at the end of the lead screw 23 by a flat key to realize torque transmission.

[0029] The output shaft of the drive motor 22 is keyed to a lead screw 23. Both ends of the lead screw 23 are connected to the plate 1 through the first bearing seat 25. Both ends of the lead screw 23 are respectively installed on the inner ring of the first bearing seat 25. The outer ring of the first bearing seat 25 is fixed to the plate 1 through the bearing seat, forming a stable rotational support structure.

[0030] Specifically, guide rods 24 are provided on both sides of the lead screw 23, and second bearing seats 26 are provided at both ends of the guide rods 24. The two ends of the guide rods 24 are connected to the plate 1 through the second bearing seats 26.

[0031] When the drive motor 22 is powered on, the output shaft drives the lead screw 23 to rotate synchronously. Since the base plate 31 of the mold assembly 3 is threadedly engaged with the lead screw 23, and the two sides of the base plate 31 are slidably connected to the guide rod 24, the rotational motion of the lead screw 23 is converted into the linear motion of the mold assembly 3. By controlling the forward and reverse rotation of the drive motor 22, the mold assembly 3 can move left and right back and forth on the top of the plate 1.

[0032] Furthermore, the mold assembly 3 includes a base plate 31 threadedly connected to the lead screw 23. The bottom of the base plate 31 is provided with a trapezoidal threaded hole that matches the lead screw 23, and linear bearings are symmetrically arranged on both sides to cooperate with the guide rod 24.

[0033] The top of the base plate 31 is provided with a detachable connecting plate 32. The top of the base plate 31 is engaged with the T-shaped slider at the bottom of the connecting plate 32 through a T-slot and is fastened with bolts to achieve a detachable connection.

[0034] The connecting plate 32 is equipped with several molds 33, and four mold 33 mounting positions are evenly distributed on the connecting plate 32. Each mounting position is engaged with the positioning hole on the bottom of the mold 33 by a positioning pin to ensure the installation position accuracy of the mold 33. The molds 33 adopt a modular design, and the corresponding molds 33 can be replaced according to different specifications of rubber sealing rings.

[0035] When the drive assembly 2 moves the mold assembly 3 to the filling station, the operator places the pre-formed rubber material into the cavity of the mold 33; then the mold assembly 3 moves to the vulcanization station and cooperates with the extrusion assembly 4 to complete the vulcanization process. By changing the mold 33 of different specifications, the production needs of rubber sealing rings of various sizes can be met.

[0036] In this embodiment, the bottom of the plate 1 is bolted to the bottom box 7, and the top of the bottom box 7 is fixedly connected to the extrusion assembly 4. The mold assembly 3 is used at least for extruding the mold assembly 3.

[0037] Furthermore, the extrusion assembly 4 includes a telescopic rod 43 welded to the top of the base box 7. A connecting plate 41 is provided at the top of the telescopic rod 43, and an extrusion plate 42 is provided at the bottom of the connecting plate 41. The top of the telescopic rod 43 is connected to the bottom of the connecting plate 41 through a flange. The connecting plate 41 is a rectangular steel plate structure with third bearing seats 44 symmetrically arranged on both sides. The extrusion plate 42 is fixed to the bottom of the connecting plate 41 by four bolts. The bottom surface of the extrusion plate 42 is machined with a high-temperature resistant rubber pad for uniformly transmitting pressure.

[0038] Furthermore, a fourth bearing seat 71 is provided on both sides of the base box 7, and a heating component 6 is provided on the other side of the base box 7. The heating component 6 uses electric heating tubes (model: DWQ-800) evenly distributed inside the base box 7, and transfers heat to the mold 33 through a heat transfer oil circulation system. A temperature sensor (model: PT100) is installed inside the mold 33 to monitor the temperature in real time and feed it back to the PLC control system. When the temperature is lower than the set value, the control system automatically adjusts the heating power; when the set temperature is reached within ±2℃, it enters a constant temperature state to ensure stable temperature during the vulcanization process.

[0039] In this embodiment, a lifting assembly 5 is provided on one side of the base box 7. The lifting assembly 5 is used at least for lifting the mold assembly 3.

[0040] Furthermore, the lifting assembly 5 includes a first protective cover 51 and a second protective cover 52 bolted to both sides of the base box 7. The first protective cover 51 and the second protective cover 52 of the lifting assembly 5 are respectively fixed to both sides of the base box 7 by bolts to protect the internal gears and motor. The first protective cover 51 is equipped with a servo motor 53. The output shaft of the servo motor 53 is rigidly connected to one end of the connecting rod 55 through a coupling.

[0041] The output shaft of the servo motor 53 is keyed to a connecting rod 55. Gear 54 is provided at both ends of the outer wall of the connecting rod 55. Gear 54 is installed at both ends of the connecting rod 55. Gear 54 meshes with gear 57 at the end of the lead screw 56 to form a gear transmission pair.

[0042] Understandably, both sides of the bottom box 7 are equipped with lead screw 2 56, one end of lead screw 2 56 is equipped with gear 2 57, gear 2 57 and gear 1 54 together form a gear set, and the other end of lead screw 2 56 is equipped with limit block 58. Limit block 58 is installed on the other end of lead screw 2 56. Limit block 58 adopts a rubber buffer structure to prevent overtravel.

[0043] When the servo motor 53 starts, it drives the connecting rod 55 to rotate synchronously. The gear 1 54 at both ends of the connecting rod 55 drives the gear 2 57, causing the lead screw 2 56 to rotate. Since the lead screw 2 56 is threadedly connected to the third bearing seat 44, the rotational motion of the lead screw 2 56 is converted into the lifting motion of the extrusion assembly 4.

[0044] It should be noted that the heating component 6 is controlled automatically by a controller. The controller's control circuit can be easily programmed by those skilled in the art and is common knowledge in the field. Furthermore, since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail here.

[0045] Working steps: 1. Start the drive assembly 2. The drive motor 22 drives the lead screw 23 to rotate, so that one set of mold assemblies 3 can be moved to a position that is easy to operate.

[0046] 2. Place the cut rubber raw material into the cavity of mold 33 to complete the raw material filling;

[0047] Third, restart the drive motor 22, and move the mold assembly 3 filled with raw materials to the top of the extrusion assembly 4 through the lead screw 23; at the same time, another set of mold assemblies 3 moves to the idle station to perform the raw material filling operation;

[0048] Fourth, start the lifting assembly 5. The servo motor 53 drives the lead screw 56 to rotate through the connecting rod 55, gear 1 54 and gear 2 57, so that the mold assembly 3 is lowered to the position to cooperate with the extrusion assembly 4.

[0049] The telescopic rod 43 of the extrusion assembly 4 pushes the connecting plate 41 and the extrusion plate 42 to rise, applying pressure to the mold 33;

[0050] Fifth, the heating component 6 on the bottom box 7 starts to work, heating the mold 33 to complete the vulcanization reaction of the rubber under the set temperature, pressure and time conditions;

[0051] 6. After vulcanization is completed, the telescopic rod 43 of the extrusion assembly 4 descends to release the pressure on the mold 33.

[0052] Activate lifting component 5 to raise mold component 3;

[0053] 7. Drive component 2 to work and move the vulcanized mold component 3 to a position that is easy to operate. Manually or with tools, remove the vulcanized rubber sealing ring and perform subsequent processing such as deflashing.

[0054] 8. The mold assembly 3 that has completed demolding and part removal is moved to an idle station for the next round of raw material loading; at the same time, the mold assembly 3 that has completed loading on the other side is moved above the extrusion assembly 4, and the steps are repeated to achieve continuous cycle production.

[0055] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
