Problems solved by technology

[0005] However, in conventional cooling devices such as die-casting molds, the cooling water supplied to the cooling water channel increases the oxygen concentration by the amount of gas supplied from the pressurizing device, so if the cooling water returns to the deoxidizing device in this state, the deoxidizing effect will be reduced. bad question

Abstract

The invention provides a mould cooling device, which inhibits the condition that the deaeration effect of the deaeration device which is arranged inside the cooling cycling tank is deteriorating. The invention comprises a mould (2) having a first cooling water path (11), cooling water circulation tank (3) which has a deaeration device (31) which performs deaeration on the cooling water (W) cooling the mould and stores the cooling water (W), a pressurizing device (4) which is communicated with the water circulation tank (3) and pushes the pressurized cooling water to the first cooling water path (11) and supplies gas to the first cooling water path (11), a middle tank (5) which stores the pressurized cooling water which is discharged from the first cooling water path (11) and discharges the cooling water to the air, a first cooling water return path (17) which is used as a first cooling water return device, a first cooling water return pump (17p), and a first cooling water return pump motor (17m), wherein the cooling water stored in the middle tank (5) returns to the cooling water circulation tank (3).

Description

technical field [0001] The present invention relates to a cooling device for a mold that supplies gas to a cooling water channel. Background technique [0002] Conventionally, cooling devices such as die-casting molds are known which supply cooling water together with pressurized gas supplied from a pressurized gas supply source (pressurizing device) to the inside of the mold (cooling water path) (for example, refer to Patent Document 1). In addition, generally, the higher the oxygen concentration of the cooling water, the easier it is to generate rust in the cooling water piping, so the cooling water supplied to the cooling water channel is deoxidized by a deoxidizer (for example, refer to Patent Document 2).
