Installing a good set of casting mold shells not only requires good stamping mold standards and high-precision manufacturing processes, but also requires "standardization" and does not allow the existence of "similar" definitions.

1. During injection, it should be smooth, without jamming or abnormal noise.

2. The surface of the inclined guide pillar should be polished and polished, and the top of the inclined wall should be smaller than the surface of the core.

3. Rolling components should have oil grooves, and the surface of hardware parts processing needs to undergo nitriding treatment. After solving the problem, the surface strength should be above HV700.

4. All top rods should have precise positioning for rotation, and each top rod should have a serial number.

5. Use limit blocks to limit the injection spacing

6. Calibration of the torsion spring should be done using standard parts, and both sides of the torsion spring should not be polished or sawn off.

7. The sliding block and core pulling should have a stroke arrangement limit, and the small sliding block should be limited by a torsion spring. When installing the torsion spring, wave screws can be used; The hydraulic cylinder core pulling must have a limit switch.

8. The slider core pulling generally uses inclined guide pillars, and the angle of view of the inclined guide pillars for processing small hardware parts should be 2 ° -3 ° smaller than the angle of view of the slider clamping surface. If the slider stroke arrangement is too long, hydraulic cylinders should be used for extraction.

9. The top block fixed on the top bar should be sturdy and reliable. The non formed part of the surrounding area of the small hardware stamping process should be produced and processed with a slope of 3 ° to 5 °, and the lower edge should be rounded.
