The nozzles commonly used at present are generally straight pipes, and the strength of the nozzles is often soft due to the shallow insertion of the nozzles, the large gap between the installation holes, or the long nozzles. The difficulty of fixing the type will lead to unstable installation of the nozzle, and the pressure of the external cooling water is constantly changing. Under the impact of uneven water pressure, the nozzle is easy to tilt in the water hole, so that the cooling The uneven flow of cooling water in the tower will eventually lead to shrinkage and deformation of plastic products due to uneven cooling, as well as some unforeseen defects

Embodiment Construction
[0010] In order to further reveal the technical solutions of the present invention, the following describes the implementation of the present invention in detail in conjunction with the accompanying drawings: figure 1 As shown, a cooling device suitable for plastic molds includes a cooling water tower 2 arranged in the cavity of a plastic mold 1 and a nozzle 3 arranged in the cooling water tower 2, and the lower end of the nozzle 3 is connected to a water inlet pipe for cooling water 4. A cooling water outlet pipe 5 is connected to the lower end of the cooling water tower 2 . The external cooling water first flows into the nozzle 3, sprays out from the nozzle 3, flows into the cooling water tower 2, and then flows out from the cooling water tower 2 to complete the cycle process.
[0011] Such as figure 2 As shown, the upper end 6 of the nozzle 3 is turned outward to form four "petal" shapes, which can support the cooling tower 2 and ensure that the nozzle 3 is not easy to ti...

The invention discloses a cooling device applicable to plastic moulds. The cooling device applicable to plastic moulds comprises a cooling water tower and a spraying pipe, wherein the spraying pipe is arranged in the cooling water tower which is arranged in a cavity of a plastic mould. The upper end of the spraying pipe is turned outward to form a structure of multiple 'pedals'. The outward turned type spraying pipe is quite stable in fixation during cooling, the 'pedal' structure at the end of the spraying pipe is novel and unique, the spraying pipe is fine in spraying state and remarkable in cooling effect, molded parts can be cooled uniformly, forming period is shortened completely, and accordingly cost can be reduced while product quality is improved.
Description
technical field [0001] The invention relates to a cooling device, in particular to a cooling device for plastic moulds. Background technique [0002] In order to shorten the molding cycle of injection molds, cooling towers and water spray pipes are often used to cool the mold cavity. The nozzles commonly used at present are generally straight pipes, and the strength of the nozzles is often soft due to the shallow insertion of the nozzles, the large gap between the installation holes, or the long nozzles. The difficult fixation of the type will lead to unstable installation of the nozzle, and the pressure of the external cooling water is constantly changing. Under the impact of uneven water pressure, the nozzle is easy to tilt in the water hole, so that the cooling The uneven flow of cooling water in the tower will eventually lead to shrinkage and deformation of plastic products due to uneven cooling, as well as some unforeseen defects.
