General introduction Jig leakage testing fixture

The Airtight Test Jig (gas product inspection jig) is a product inspection jig that has the function of checking the tightness of products, details such as plastic bottles, engine air tightness testing, details assembly, mold ...

The airtight test jig is CNC machined as required at CNC-VINA. Jigs are used for checking, helping to control product gas leaks of components such as engines, machine parts ... so that errors are detected in time to eliminate substandard products. help to ensure the quality output of the product. From there, taking measures to help ensure production line productivity.

The structure and principle of the Jig's operation test airtight

The airtight test fixture is composed of the following clusters

• Frame assembly
• Pressing Cluster
• JIG cluster

The airtight test jig designed and manufactured by CNC-VINA has the advantage of simple, flexible design and structure that makes it easy and quick to replace jigs, jigs for testing other product modules together.

Principle of operation

1. The operator mounts the product to be checked on the support jig
2. After mounting the Product, the operator takes his hand away from the safety sensor operating area.
3. Product Optical Sensor detection.
4. The pressing cylinder will press the product through a fixed jig.
5. The blowing jig will blow air into the chamber of the product. When the pressure in the chamber reaches 0.5Mpa. Pressure Switch measures the pressure in the chamber for about 10 seconds.
6. The product is airtight, the product has been marked with the max combustion cylinder.
7. The cylinder is pressed back to the standby position, the head blows dust. The operator takes the product out of the machine and completes the airtight test

Mold replacement step by step

- Step 1: When changing the model, the worker presses the down button of the cylinder to confirm that the mold on the lower mold is in contact.

- Step 2: Unscrew the 2 ends of the mold stopper, use the mold hook to pull the mold gasket out.

- Step 3: Up the cylinder to go up, then remove the latch and catch the jig underneath the machine table.

–Step 4: The worker pulls the entire mold out of the forklift to wait for model replacement.

Step by step to attach the mold to the machine

–Step 1: The worker pulls the entire mold from the forklift into the jig position on the machine board.

–Step 2: Insert the pin and bolt to position the jig underneath the machine table.

–Step 3: Press the down-cylinder button to go down to match the jig on top.

Operations for maintaining airtight testing machines

• Observe the pressure gauge daily to check if the air pressure range ensures the operating pressure.
• Clean the surface and lubricate the slide, cylinder, re-align after operating time (about 3 months / 1 time).
• Clean the surface of the jig weekly with a clean cotton soaked in alcohol.
