Glass bottles and appearance of the product quality is better than a bad first mold material has a key role, in the process of glass molding, mold frequent and around 1000 ℃ melting glass (glass molding products) at the beginning of contact, the mould will always be open and close regularly, mould will be in the case of uncoordinated collisions, also can appear incomplete be mold clamp (bite) cases were incomplete staved in die corner, on the glass products, the phenomenon of the bulge affect product beautiful, appear this kind of circumstance: 1 belong to the mold material is qualitative hardness is not enough, 2 or not been spray welding mould corner, usually after all spray welding mould made of glass products for high-quality goods, but after spray welding mold will be over a period of time will appear oxidation phenomenon, appear fall off phenomenon, through the spray welding mold through also than the spray welding mold about double the price.
Glass bottle mould in high temperature in the production process, and stripping agent will produce ash after combustion and oxidation of plaque, such as not clear in time can produce a lot of damage to the mold, so it is especially important for mold maintenance.
Methods for improving the quality of glass bottle mould by Andy mould analysis:
1, product design is reasonable, choose the best structure scheme, as far as possible product designer should consider the technical requirement and the structure of the product must meet the manufacturability and feasibility of the mould manufacturing.
2, the design of the mould is the most important step to improve the quality of the mould, need to take into account many factors, including the selection of die materials, die structure of the usability and safety, the machinability of mold parts and mould maintenance convenience, these at the beginning of the design should be considered more carefully.
3, mold material selection of both to meet customer requirements for product quality, also need to consider to the cost of materials and in the strength of the set period, also according to the type of mold, using the way of working, processing speed, the main failure form factors such as material selection. For example, the main failure mode of punching die is the edge wear, and the surface hardness is high and the wear-resistant material is selected. The stamping die is mainly subjected to periodic load, which can cause the surface fatigue crack, causing the surface to flake off, and then choose the material with good surface toughness.
4. The manufacturing process of early molds is also an important part to ensure the quality of molds. The machining methods and machining precision of the mould manufacturing process can also affect the service life of the mould. Directly affect the precision of parts of the mold the whole assembly, get rid of the influence of accuracy with the device itself, through the improvement of the processing method of parts is needed, improve the level of fitter in the mold in the process of grinding with technology, to improve the processing precision of mould parts; If the overall assembly effect of the die is not up to the requirement, the chance of making the mold in the die will be increased in the test mode, and the overall quality of the mould will have a great impact.
