Description

Technical Field

[0001] The utility model relates to the field of silica gel material processing, in particular to a silica gel punching mechanism. Background Art

[0002] Silicone punching is a manufacturing process that is usually used to produce silicone products, such as silicone pads, silicone sealing rings, silicone buttons, etc. This process involves cutting silicone materials into specific shapes and sizes to meet product design requirements. Traditional silicone punching uses a silicone punching machine, which generally feeds the silicone in and then performs die-cutting. After the punching is completed, it continues to be pushed backwards. During the punching process, since silicone itself is a soft material, some of the finished products may adhere to the mold after the operation is completed and are not easy to fall off. If they are manually picked out, oil stains may adhere to the punched silicone products. In order to solve the above-mentioned problems, the utility model proposes a silicone punching mechanism.

[0006] Preferably, the connecting pipe is vertically arranged between the mold cavity and the airflow cavity and is parallel to the air guide pipe. By arranging the vertical connecting pipe, the gas can be delivered into the airflow layer to a greater extent, thereby promoting the falling of the silicone after punching.

[0009] Preferably, the air pump is a micro gear air pump, which has two meshing gears inside. When the gears rotate, the tooth grooves of the gears gradually close and move, sucking air from the inlet of the pump and delivering it to the outlet, thereby helping to better blow out the silicone product.

[0010] Compared with the prior art, the beneficial effects of the utility model are: by optimizing the structure of the stamping die, by setting an airflow cavity on the top of the die cavity of the stamping die, connecting the airflow cavity and the die cavity through a connecting pipe, and then using an air pump to supply air to the air outlet pipe, the air guide pipe, the airflow cavity, and the connecting pipe step by step, and finally pushing out the adhered silicone, thereby reducing adhesion, facilitating centralized unloading and feeding, and making production more orderly.

[0022] In specific use, the working principle of this device is:

[0023] The silicone is conveyed to one side through the conveyor table in the middle of the operating table.

Specifically: there are two meshing gears inside the air pump. When the gears rotate, the tooth grooves of the gears will gradually close and move, sucking air from the inlet of the pump and conveying it to the outlet, that is, sending the air to the outlet pipe, and then the outlet pipe is sent down step by step to the mold cavity, pushing the silicone adhered to the mold cavity to fall, facilitating the centralized transmission of silicone, while reducing the stains left by manual picking and possible safety accidents.
