[0002] Silicone ring extrusion molding generally involves first extruding a silicone tube, and then cutting the silicone tube into silicone rings. During extrusion, the existing silicone tube extrusion molding device will have a certain curvature after cooling and molding due to a certain height difference between the output end of the extrusion tube and the water tank; the existing Chinese patent with announcement number CN219381506U discloses a silicone ring extrusion molding device, which includes an extruder and a pre-cooling mechanism. The extruder includes a bottom plate, an extruder barrel, and a discharge barrel. The pre-cooling mechanism includes a conveyor belt and a cooling mechanism. The conveyor belt surface is provided with an arc bracket. The output end of the discharge barrel leads to the input end of the arc bracket. The cooling mechanism is used to cool the product transmitted on the arc bracket; the silicone tube is preliminarily cooled by the cooling mechanism to allow the surface of the silicone tube to cool and shape and maintain a straight shape. After the silicone tube is preliminarily cooled, the silicone tube is allowed to enter the cooling water tank for overall cooling and molding to avoid bending of the silicone tube after molding, thereby improving the molding quality of the product.

[0003] Although the current silicone ring extrusion molding machine can prevent the silicone tube from bending after molding by pre-cooling and then placing it in a water tank for cooling, the existing silicone ring extrusion molding machine cools the silicone tube unevenly during the pre-cooling process, and its atomizing nozzle only cools the two sides of the silicone tube, and the cold water sprayed by the atomizing nozzle cannot be recycled, which will cause waste; therefore, in response to this situation, the utility model cleverly proposes a silicone ring extrusion molding machine to solve the deficiencies in the above technical background.

A submersible pump 11 is fixedly connected to the side of the water storage bottom bin 4 away from the discharge head 2, and a water suction port 111 is provided at the bottom of the side of the submersible pump 11, and a water outlet pipe 112 is fixedly connected to the top of the submersible pump 11, and the outlet of the water outlet pipe 112 is fixedly connected to the water storage top bin 5, and the water in the water storage bottom bin 4 can be transported to the water storage top bin 5 for recycling through the submersible pump 11, thereby avoiding the waste of water resources.

[0022] Preferably, the outlet of the water outlet pipe 112 of the submersible pump 11 is higher than the horizontal plane in the water storage top chamber 5, thereby avoiding the backflow of cold water.
