Abstract

A water and gas dual-purpose pressure test machine is used for testing the pressure of a die waterway. The water and gas dual-purpose pressure test machine comprises a water storage tank which is provided with a water inlet pipe and a water outlet pipe, wherein the water inlet pipe and the water outlet pipe are respectively connected with the die waterway, and a pressure relief pipe is arranged between the water inlet pipe and the water outlet pipe; a master water inlet valve which is arranged on the water inlet pipe and is provided with two branch water inlet valves, and the branch water inlet valves are respectively provided with pressure gauges; a water pumping motor which is arranged between the water storage tank and the master water inlet valve and is connected with the water inlet pipe; a gas inlet valve which is arranged between the master water inlet valve and the branch water inlet valve and is connected with the water inlet pipe; a first water outlet valve which is arranged on the pressure relief pipe; and a second water outlet valve which is arranged on the water outlet pipe. The water and gas dual-purpose pressure test machine provided by the invention has a simple structure and is simple and convenient to operate, and the abnormity determination is accurate in the pressure test process, and no pollution is caused to the operating environment.

Description

【Technical field】 [0001] The invention relates to a pressure testing machine, in particular to a water-air dual-purpose pressure testing machine for testing the pressure of a mold waterway. 【Background technique】 [0002] There are two types of existing mold waterway pressure testing machines, one is the air pressure testing machine, which cannot accurately determine the abnormal position; the other is the manual pump water testing machine, when using the manual pump water testing machine , The operator is time-consuming and laborious, and when there is residual water in the mold waterway after the pressure test, it needs to be blown out with an air gun, and the residual water will pollute the working environment. [0003] In view of this, it is necessary to develop a new type of water-air dual-purpose pressure testing machine. The water-air dual-purpose pressure testing machine is simple and convenient to operate, and the abnormality judgment during the pressure test proces...
