Description

Technical Field

[0001] The invention relates to the field of rubber component processing, and in particular to an automatic feeding rubber sealing component hot pressing molding device. Background Art

[0002] Automobile rubber seals are an indispensable and important part in automobile manufacturing. They mainly play a variety of roles, such as preventing the leakage of media, preventing external dust and impurities from entering the machine, shock absorption, sound insulation, and heat insulation. In the production process of rubber seals, since rubber is relatively soft, if the force is uneven during loading and unloading, the rubber parts will be deformed, affecting the processing quality of the workpiece.

[0003] To this end, Chinese patent CN116080050B discloses a high-efficiency rubber hot pressing molding equipment, which realizes the automated hot pressing molding of the waterstop and the automatic loading of the rubber raw materials of the waterstop, avoiding the need to manually lay the upper layer of rubber raw materials in the existing waterstop production process, and placing a molding rod between the two layers of rubber raw materials, which makes the upper layer of manually laid rubber raw materials difficult to adjust, and cleans the residual rubber on the lower template during demolding, which facilitates subsequent production and avoids the breakage of the molded waterstop due to inconsistent force during manual demolding, making the entire section scrapped.

[0004] However, the existing hot pressing molding equipment uses a cleaning wheel for cleaning and demolding. However, due to the high friction coefficient of rubber, after the cleaning wheel contacts the workpiece, it stops rotating due to the friction force. Continuing to move will cause severe friction with the mold, and thus cannot play its due cleaning role. Once the cleaning wheel rotates in the opposite direction during movement, it will also push the cleaned waste onto the workpiece, causing the waste to fit the workpiece, affecting the quality of the workpiece, and once relative sliding occurs between the cleaning wheel and the workpiece, the workpiece may be pulled to cause deformation of the workpiece, and after cleaning, the mold needs to be disassembled, and repeated disassembly and assembly of the mold will increase the wear of the mold, further affecting the processing accuracy of the workpiece.

After the sensing component 44 senses that the fixed frame 341 contacts the fixed bracket 425, a feedback signal To the controller, and then the controller sends a signal to the first rotation driver 421. After receiving the signal, the first rotation driver 421 drives the first screw 423 to rotate, and the first screw 423 drives the movable seat 424 threadedly connected thereto to move, and the movable seat 424 pushes the fixed frame 341 on the second cleaning frame 32 through the push block 4241, thereby driving the second cleaning frame 32 to move toward the other end of the workpiece 5, and the waste on the lower mold 21 is shoveled into the collecting box 33 through the movement of the second cleaning frame 32, and the workpiece 5 is supported by the second guide roller 331 on the collecting box 33, thereby completing the continuous demolding of the workpiece 5.

[0048] Reference Fig.10 and Fig.11 : The limiting assembly includes a limiting block 431 and a first elastic member 432; the limiting block 431 is slidably mounted on the fixed bracket 425, and the limiting block 431 abuts against the movable seat 424; the two ends of the first elastic member 432 are respectively connected to the limiting block 431 and the fixed bracket 425; in the working state, when the lifting assembly 41 drives the second cleaning frame 32 to move upward, after the second cleaning frame 32 contacts the limiting block 431, the second cleaning frame 32 overcomes the elastic force of the first elastic member 432 to push the limiting block 431 to move, and controls the limiting block 431 to separate from the movable seat 424.

[0049] The present invention realizes the function of limiting the movement of the movable seat 424 through the limiting block 431 and the first elastic member 432 . When the lifting assembly 41 does not drive the second cleaning frame 32 to rise, the limit block 431 is in an extended state under the elastic force of the first elastic member 432, and the movable seat 424 is restricted from moving by the limit block 431. When the lifting assembly 41 controls the second cleaning frame 32 to rise, the fixed frame 341 on the second cleaning frame 32 contacts the limit block 431, overcomes the elastic force of the first elastic member 432 to push the limit block 431, so that the limit block 431 is separated from the movable seat 424, and then the movable seat 424 is driven to move by the first linear drive assembly 42. At this time, the second cleaning frame 32 is continuously in an upward state under the support of the push frame 412, so that the movable seat 424 can move smoothly, and the limit block 431 is provided with an inclined surface, so that when the movable seat 424 drives the second cleaning frame 32 to reset, the limit block 431 is pushed to contract by squeezing the inclined surface on the limit block 431, so that the second cleaning frame 32 and the movable seat 424 are reset smoothly.

The second rotation driver 251 is arranged on the frame 1, and the second screw 252 is transmission-connected to the driving end of the second rotation driver 251, and the second screw 252 is threadedly connected to the support plate 24.

[0051] The present invention realizes the function of controlling the movement of the lower mold 21 on the frame 1 through the guide rail 23, the support plate 24 and the second linear drive assembly 25, thereby facilitating the operator to maintain and replace the lower mold 21. The second rotary driver 251 is preferably a servo motor, which is electrically connected to the controller; when the lower mold 21 needs to be maintained or replaced, the operator sends a signal to the second rotary driver 251 through the controller, and after receiving the signal, the second rotary driver 251 drives the support plate 24 to move along the guide rail 23, and the guide rail 23 drives the lower mold 21 to move, so that the lower mold 21 is moved out of the frame 1, thereby facilitating the operator to disassemble and assemble the lower mold 21.

[0053] The present invention realizes the function of limiting the lifting range of the second guide rod 442 through the limit ring 445. In order to ensure the sensing accuracy of the sensing component 44, it is necessary to control the second guide rod 442 and the third abutment block 443 to reset after the second cleaning frame 32 and the first cleaning frame 31 move downward. For this purpose, a second elastic member 444 is provided, and in order to enable the third abutment block 443 to actively push the first cleaning frame 31 and the second cleaning frame 32 to reset, it is necessary to ensure that the second elastic member 444 has sufficient elastic force. For this purpose, a limit ring 445 is provided to limit the moving range of the second guide rod 442, thereby ensuring that when the third abutment block 443 is reset under the elastic force of the second elastic member 444, the second elastic member 444 has a certain pre-tightening force on the third abutment block 443, thereby avoiding the reset of the third abutment block 443 being affected by the friction between the second guide rod 442 and the third support 441.
