Description

Technical Field

[0001] The utility model relates to the technical field of rubber injection machines, in particular to a feeding mechanism of a rubber injection machine. Background Art

[0002] The rubber injection machine is a precision automated equipment, mainly used to produce rubber products, such as tires, seals, shock absorbers, etc. It injects molten rubber into the mold through a high-pressure system, and solidifies it at a certain temperature and pressure to form the required shape and size. The whole process is automatically completed by a computer control system, including feeding, metering, injection, pressure holding, cooling and demoulding steps. The rubber injection machine uses advanced sensors and actuators to ensure precise pressure and flow control, as well as high-quality product output.

[0003] The patent document with application number CN202220258769.3 discloses a feeding mechanism of a rubber injection machine, which includes a shell, on which a rotating rod 1 is hinged, and a rotating rod 2 is hinged at the end of the rotating rod 1, and a push rod is hinged on the rotating rod 2, and the push rod is slidably connected to the shell in the vertical direction, and a round block is fixedly connected to the end of the push rod, and the round block is provided with circular holes distributed circumferentially. In the utility model, the push handle is rotated so that the rotating rod 2 pushes the push rod to move downward in the vertical direction during the rotation, so that the pressure block and the resistance block push the material in the silo to move downward to feed the material during the movement. When the resistance block pushes the material to move, it will cause the pressure block to move upward to compress the spring, so that the pressure block can better play its role and will not be damaged when pushing the material. The pressure block has a certain buffering effect when it plays its role, and the operation process omits cumbersome steps, which is convenient for the staff to operate. Based on the search of the above-mentioned patents and combined with the feeding mechanism of the rubber injection machine in the prior art, it is found that the feeding mechanism of the rubber injection machine needs to convey raw materials when it is used, but the existing mechanism cannot protect the raw materials during the conveying process, especially the raw materials will continue to lose heat during the conveying process, and the raw materials may harden and cannot be effectively conveyed, thereby causing damage to the mechanism.
