Description
The technical field is as follows:
the utility model belongs to the mechanical equipment field, concretely relates to detection of cooling water pipeline sealing performance in thermoforming mould.
Background art:
the cooling of the hot forming die during die assembly is an important step in the hot forming process, and has a great influence on the quality of products. Whether the cooling process effect meets the design requirements or not is influenced by the sealing performance of a cooling water pipeline in the die. If the cooling pipeline has a leakage point, the cooling water continuously leaks to cause the change of the cooling temperature, so that the cooling effect gradually decreases, the cooling efficiency is reduced, and the process is greatly influenced. In the prior art, in the hot forming process, a process and a device for detecting the sealing performance of a cooling pipeline in a mold are not available, so that the mold with the cooling pipeline not meeting the sealing requirement cannot be eliminated, the quality of hot forming products is influenced, and even waste products are produced.
The utility model has the following contents:
the utility model aims at providing a be used for cooling pipeline sealing performance detection device in thermoforming mould for the detection of cooling pipeline in thermoforming mould overcomes prior art thermoforming mould and uses the above-mentioned not enough that exists.
The utility model discloses a measuring device includes: the water pump driving motor, the storage water tank, connect the storage water tank and set up the conduit line of cooling line water inlet in the thermoforming mould, install the booster water pump on the conduit line, the check valve on the conduit line of booster water pump export or outlet side conduit line, use the running water delivery pipe that tee bend inserted the conduit line, the moisturizing stop valve before the running water gets into the conduit line, the ball valve that is close to mould cooling line import on the conduit line, the pressure regulating drain line of connecting conduit line and water tank between check valve to the running water import, install the air-vent valve on pressure regulating drain line, install the manometer on the conduit line, install the measurement water drain pipe at the cooling line export in the thermoforming mould, install the drainage ball valve on measuring the.
The utility model discloses a working process is: when the pressure regulating valve is used for the first time, the pressure regulating valve is adjusted to overflow when the pressure regulating valve reaches 10kg/cm 2. And opening a ball valve on the water pipe at the inlet of the cooling water channel of the mold, opening the ball valve on the measuring water drainage pipe for a little exhaust, and opening a stop valve on a tap water supply pipe to fill the tap water in the cooling channel of the mold. And (3) closing a ball valve and a tap water supply stop valve on the measuring water drain pipe after water flows out of the water drain pipe to be measured, starting a motor, driving a pressurizing water pump, closing the motor when a pressure gauge shows that the pressure of the closed pipeline reaches a set pressure (usually 10kg/cm2), maintaining the pressure for 20 minutes, and if the numerical value of the pressure gauge changes, indicating that the cooling pipeline has leakage, and retesting after solving the leakage problem. If the value of the pressure gauge is not changed, the cooling pipeline is not leaked, and the cooling pipeline can be normally used.
The utility model has the advantages that: the device for detecting the sealing performance of the cooling water pipeline in the thermal forming die detects the thermal forming die with the cooling pipeline not meeting the requirement, and ensures the quality of the thermal forming product. The self liquid filling and the pressurization of the device are separated, and the large flow liquid filling is performed firstly, and then the small flow pressurization is performed. The large flow is supplied by tap water, and the small flow is supplied by a small-sized electric pressure test pump. Compact structure, small occupied space and low cost, and completely meets the use requirements.
