China injection Mold quality control points

1，In the process of mould processing quality control

1. Mold parts processing quality control.

1) for each part drawings, technical requirements, completion time requirements; Did not note tolerances size used 1/2 it12 tolerance grade or match.

2) machining personnel shall be in accordance with the requirements of parts drawing size, and asked after machining self-inspection, and specified on the drawing

Self-check result and date (signature). For measurements, the introspection of artifacts, once found fault inspection the size of the workpiece, the losses caused by twice to punish processors output, and order as soon as possible to complete reproduction of the workpiece.

3) fitter group machining all outside the scope of the cooperation, should be arranged by the workshop processing, finish machining JingJian

Returned to the bench after inspection qualified team, by the fitter leader acceptance, and output by the workshop management personnel registration processing personnel.

4) fitter team internal processing parts, the team leader is responsible for the control of the processing quality, and indicate the likely on the drawings

The size of the changes.

2. The quality control of mold assembly

1) assembly fitter are responsible for the quality of a complete set of mold, fitter carefully check before assembly parts quality (including the materials

Heat treatment, machining quality), for the unqualified parts may affect the whole mold quality, should change in time or reprocessed.

2) fitter carefully crafted in the assembly process, to ensure that the mold assembly accuracy, make it to the design requirements of using

Life, the production efficiency, produce comply with the design requirements of qualified products.

3) after completion of assembly, responsibility fitter mold of a complete set of self-inspection again carefully, to ensure the success of the test qualified, after inspection

Open the mould, fill in test application form, hand in workshop management.

2. Mold production of products subject to quality inspection, comply with the design requirements or customer requirements.

3. The mould all sports institutions, all should guide sliding flexible, motion is stable and reliable, fit clearance, appropriate and factory processing lubrication.

4. The mold parting surface and all molding surface, factory should make antirust processing. 5. Die appearance and installation dimensions, deal with the following conditions:

1) the edge of the template should be 2 x45 "chamfering, mounting surface should be smooth level off, should not have prominent screw head, pin

Head, burr and injury.

2) the reference Angle of mould should be seal on mould number, there is no lifting and moving mold, rings with screw

Pit.

3) the size of the tooling parts, shall comply with the selected models.

4) separate surface except the guide sleeve hole, pin hole, all the holes in the process of mould manufacturing process, screw hole should be blocked

Plug and parting surface level.

The workshop managers and designers should be the factory mold for detailed inspection, signing after confirm qualified mold certificate, registered fitter output by workshop management personnel.
