Water return device

Abstract

The invention discloses a water return device, belongs to the technical field of dies and aims at solving the problem that existing water return boxes are prone to causing air pressure which counter-presses a die cooling terminal and inconvenient to observe. The water return device comprises a water return box and a funnel, the water return box is communicated with the funnel through an exhaust pipe, multiple pressure-release exhaust holes are formed in the top of the water return box and used for preventing the water return box with over-high pressure from causing air pressure which counter-presses the die cooling terminal, and an observation window is arranged on the water return box. The water return device can prevent the water return box with over-high pressure from causing the air pressure which counter-presses the die cooling terminal, and water return condition of each water return pipe and whether blockage occurs or not can be observed visually.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a water return device. Background technique [0002] The return water tank is usually used in the field of mold technology to cool the finished product to a certain temperature requirement. The existing return water tank generally does not have a pressure relief vent or a glass panel, and the vent of the return water tank The design is also relatively simple, and the existing return water tank has the following disadvantages: the pressure of the return water tank is too high, which may easily cause the air pressure back pressure to the mold cooling terminal; the user cannot intuitively see the return water status of each return water pipe and whether it is blocked; Water vapor is easy to spray directly outside and affect the surrounding environment. Therefore, the present invention urgently needs to provide a novel return water device so as to be better used in the technical field...
