What are the technical requirements for bottle cap mold assembly?

A. Ensure the length of the opening and closing travel of the bottle cap mold, and the injection used should meet the requirements.

B. The assembled bottle cap mold should be marked with the molded shell number, and the large, small and medium-sized injection molds should be set up with lifting holes.

C. The overall assembly precision of bottle cap mold is stipulated

1. The exposed part of the obtuse Angle of the bottle cap mold should be blunt, the installation surface should be smooth and leveled, the top of the screw and screw head should not be higher than the installation datum, and there is no significant burr, dent and deformation.

2. The raw materials, appearance, specifications, precision, roughness and heat treatment process of each part of the mold should comply with the sample drawing provisions, and the surface of each part is not allowed to damage.

3. All the active positions of the mold should ensure that the parts are appropriate, the gap between them is moderate, the posture is reliable, and the fitness movement is stable.

4. All standard parts on the mold should be tightened and reliable, without any loosening.

D. The specifications and models of the mold embryos used in the bottle cap mold should be able to consider the technical standards needed for injection products.

E. After assembly, moving template along the positioning pin up and down when moving, should be stable without conduction block, positioning pin and guide column with each other precision should meet the requirements of the specification, and the gap is uniform.

Be sure to ensure the relative position accuracy between the molds parts, especially when some specifications and a number of parts specifications are in contact, such as the analysis of the two plane must ensure that the parallel plane.

F. after the assembly of the mold and before the mold, in the mold must be inseparable touch, there can not be all the gap, in line with the requirements of the sample.

G. The precise positioning of the bottle cap mold should be accurate and reliable when closing the mold, and the flow of the plastic parts should be smooth and unobstructed.
