Injection mold in the assembly after the completion of the work, the need for mold mold trial before the inspection, has been found to mold design and manufacturing problems, so as to correct, the specific contents are as follows.
  一.Visual inspection, injection mold. 1.forming part, gating system and melt contact surface should be smooth, flat, no collapse, defects such as scars.2.Closing stroke  mould installed on the machine, each with the spot size, form, mold, mold release from the workpiece requirements shall be in accordance with the relevant conditions of the equipment. 3.die on the production and mold marks, various joints, valves, accessories, spare parts should be complete. 4.Gap with the sliding parts shall conform to the requirements, starting and ending position correctly, inlaying fastening parts should be fastened firmly. 5.for injection molding corrosive, the surface of the mold cavity should be chrome and antiseptic treatment. 6.The appearance of the part mold should not have acute angle, large, medium-sized mold should have for the lifting rings, hanging hole. 7.bearing parts in contact with each other, should be a reasonable bearing area and pressure, avoid direct bear extrusion. 8.The stability of mold is good, have enough strength, work force should be balanced, stable movement.
  二. mold idle check. Die after installation, must pass through the air to check, in order to find the problem further, and to solve the problem. 1.will die slowly closing, after clamping the joint surface should be in close contact, there shall be no gap.  2.The part stripping mechanism should ensure smooth release, in order to remove the plastic waste and pouring system. 3.movable core, ejection and guide movement should be smooth slide, flexible, reliable action coordination. 4.check the locking mechanism, should be able to reliably, safely locking, all fasteners shall not have any loose. 5.of the pneumatic, hydraulic control system is correct, no leakage, no excessive vibration, the normal operation of the valve. 6.The cooling system water should be smooth, no water leakage, a variety of control valve control normal.
