226. Plastic Mold Manufacturing Standardization Requirements
To improve the quality of mold grade quality to minimize mold complaints to the customer satisfaction of the mold, the plastic mold manufacturing summarize common problems, draw conclusions, and the establishment of standards, the required implementation.1. Less than the 2020 model embryo, a, b between the board needs to be done pry pit; more than 2020 templates including the ejector mold base plate all have to do pry between the pits.
2. Mould guide pins and bushings and exhaust ducts to be machined to prevent the guide pins and bushings and strain.
3. Mold may not have sharp corners, you need to chamfer processing. Except where specified.
4. Within the mold and mold parts without consent may not have welding.
5. Outer mold must be in place to open exhaust ducts, exhaust ducts specifications, please refer to the mold design manual.
6. As far as possible avoid the use of grinding machine in the mold polishing, if you must use the grinding machine processing, oil stone province must be light (in particular sub-surface)
7. Internal model of the surface treatment of plastic planes must follow bom tables, or other formal notification of the technical requirements for implementation. Non-adhesive surface of the processing of bit lines (line cutting, milling machines, cnc bed gongs, sparks machine) but also light oil stone province.
8. All material within the mold, mold base level requirements must be based on orders, or formal confirmation of the design review process in the technical requirements for procurement.
9. All internal model before and after the mold, inserts, line position, slant, straight top (push block), and chickens need to shovel the bottom or back side of a circular hole machining position, and the hardness of the material were carved out.
10. Line position, push the block, shovel chicken, jack mouth and other important parts to wear nitride hardening process must be carried out.
11. Line position must have a position.
12. Line position angle pin must be pressed, can not move and loose.
13. Lifters must wear a hard seat material.
14. Flow channel and into the plastic bits need to Provincial Light 400-600.
15. Thimble, Secretary extinguishers, shut thimble, the lifter and ejector plate to be engraved with the corresponding identification code, easy to install.
16. Thimble or dme by hasco standards, the choice of which depends on the bom form or other technical requirements for formal notification of the mold.
17. Processing carrying water apron ("o" ring) slot, you need to set aside 0.25mm gap side, the general apron to preload 0.5 ~ 0.8mm. If you do not pay attention to it, pressure can easily be damaged apron out, resulting in leakage.
