Abstract

The invention provides a die leakage detection device which includes a waterway mechanism, an air channel mechanism, a three-way connection mechanism and a die connection hole connection pipe. The waterway mechanism, the air channel mechanism and the die connection hole connection pipe are connected with one way of the three-way connection mechanism. The waterway mechanism includes a water inlet pipe and a waterway switching valve. The air channel mechanism includes an air supplying pipe, an air channel switching valve, an air supplying device and an air channel pressure regulating device. The die connection hole connection pipe is connected with a die channel. The thee-way connection mechanism is a tee joint. The air channel pressure regulating device is a pressure gauge. The air channel pressure regulating device includes a pressure gauge and an air filter. The tee joint is a pipe connection part made of a PVC material or an iron material. The die leakage detection device is easy to operate and capable of reducing manual cost; detection water pressure is adjustable and even and stable so that a problem that the pressure is unstable because of manual operations so that leakage points are not obvious is solved and thus tiny leakage points are easier to find and the leakage points can be found more timely and accurately; and the die is corrected according to the leakage points so that efficiency of leakage point detection is improved.

Description

Technical field [0001] The invention relates to the technical field of mold leakage detection, in particular to a mold leakage detection device for detecting whether there is leakage in a mold channel. Background technique [0002] At present, with the development of society and the continuous increase of domestic mold companies, after the completion of mold production, it is necessary to test whether the mold’s cooling water channel, oil channel, air channel, etc. leak or not. This test directly determines whether the mold is in the trial mode. It can be cooled normally and whether the mould can work normally. The existing testing and testing devices generally consist of a manual pressure test pump consisting of a water tank, a pressure pump, a manual pressure rocker, a pressure gauge and an output nozzle. When using, you first need to add water to the water tank of this device, and connect the quick-insertion nozzle of the outlet to the mold with a water pipe, and then drive t...
