[0002] After the tubular rubber product is processed in the injection molding machine, the mold core is usually taken out of the injection molding machine together with the product. At this time, the tubular rubber product is sleeved on the axial mold core and needs to be demolded to peel the product off the mold core. In the prior art, the demolding process is usually performed directly by manual operation, and the work efficiency is low. When the rubber product is just taken out of the injection molding machine, it has a certain viscosity and the rubber product adheres to the mold core, making it difficult to peel the rubber product from the mold core. Direct manual peeling is likely to cause damage to the product.

[0003] The prior art patent (CN212920284U) discloses a rubber product demoulding auxiliary tooling, including a support frame, a moving mechanism, an air pipe and a clamp. The moving mechanism and the clamp are both fixed on the support frame. The air pipe is connected to the gas source, and one end of the air pipe is an air outlet port. The air pipe is driven by the moving mechanism to achieve mobility. When the mold core and the rubber product are clamped on the clamp, the moving mechanism can drive the air outlet port of the air pipe to be inserted into the mold core, and the gas is blown out from the air outlet port of the air pipe and blown between the mold core and the rubber product. The application uses gas to assist the separation of the mold core and the rubber product. In the process of moving the entire tooling away, the clamp clamps the rubber product and slowly peels it off from the mold core to achieve demoulding, which greatly improves the demoulding efficiency. During the demoulding process, the gas effectively assists the separation of the rubber product and the mold core to ensure the quality of the rubber product.
