[0002] The backrest design of children's toilet seats is mainly to provide additional support to help babies maintain balance during excretion, especially when they need to strain to defecate.

[0003] At present, the backrests of children's toilet seats made of PET material are injection-molded by injection molds. After the products are formed, they are cooled by a water cooling device. The existing circulating water cooling mechanism of the injection mold recovers the used coolant into the water cooling mechanism for recycling. However, when the existing coolant is recovered, it absorbs the temperature of the mold products, resulting in an increase in its own temperature. If it is directly recovered into the cooling mechanism, it will affect the overall temperature of the coolant and cause poor cooling. Summary of the Utility Model

If it is directly recovered into the cooling mechanism, it will affect the overall temperature of the coolant and cause poor cooling, and it is rather troublesome to install the belt.

[0005] To achieve the above purpose, the utility model provides the following technical solutions: including a mold body, a water inlet nozzle, and a discharge nozzle; the discharge nozzle is arranged at the water outlet end of the mold body, a coolant tank is arranged on the outer wall of the mold body, a circulation mechanism is arranged inside the coolant tank, the circulation mechanism is used to circulate the coolant inside the mold body, a cooling tank is arranged on the outer wall of the mold body at the position of the discharge nozzle, one end of the discharge nozzle extends into the cooling tank, a flow splitter is connected to one end of the discharge nozzle, a plurality of nozzles are arranged at the low end of the flow splitter, heat dissipation fins are fixedly connected horizontally inside the cooling tank, a delay plate is arranged inside the cooling tank, and a fan is arranged on one side of the cooling tank, and the fan is opposite to the delay plate.

[0006] Preferably, the circulation mechanism includes a first water pump, a first extraction pipe, a first conduit, a second water pump, a second extraction pipe, and a second conduit. The first water pump is arranged inside the coolant tank. One end of the first extraction pipe is communicated with the water inlet end of the first water pump, and one end of the first extraction pipe extends into the cooling box.

One end of the second conduit is communicated with the water outlet end of the second water pump, and the other end of the second conduit is communicated with the water inlet nozzle.

[0007] Preferably, a plurality of round holes are respectively opened at the lower ends of the plurality of nozzles. The flow divider is located above the heat dissipation fins, and one end of the heat dissipation fins extends to the outside of the cooling box.

[0010] Preferably, the cooling box and the coolant tank are respectively located on the same module.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: Through the flow divider arranged inside the cooling box, the coolant is dispersed and discharged to flow onto the heat dissipation fins. By contacting the heat dissipation fins with the coolant, the heat in the coolant is absorbed to achieve the first cooling. The subsequent coolant flows onto the delay plate and slowly flows downward. By connecting the fan to the power supply, the coolant is cooled for the second time. Finally, the coolant drips to the bottom of the cooling box. Through cooling the recycled coolant twice, the temperature of the recycled coolant is maintained well, and the toilet PET backrest inside the mold body can be cooled and formed better.
