Mold quality includes the following aspects:
(1) product quality: product size stability, compliance, product surface finish, product material utilization rate, etc.;
(2)The service life: on the premise of ensuring the quality of products, the number of work cycle or the number of parts produced by the mold can be completed;
(3) the use of mold maintenance: is the most convenient to use, stripping easy, production assistance time as short as possible;
(4) of repair costs, repair cycle and so on.
Basic way to improve the quality of the mould, the design of the mould is the most important step to improve the quality of the mould, need to consider 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. Mold manufacturing process is to ensure the quality of an important part of the mold, mold manufacturing process and machining precision will also affect the service life of the mold. The precision of each part has a direct impact on the overall assembly of the mold. In addition to the influence of the precision of the equipment itself, the machining method of the parts should be improved to improve the technical level of the fitter in the process of mold grinding and fitting, so as to improve the machining precision of the mold parts. To strengthen the surface of the main forming parts of the mould, so as to improve the wear resistance of the surface of the mould parts and improve the quality of the mould. The correct use and maintenance of molds is also a major factor to improve the quality of molds.
For example: mold installation and debugging should be appropriate, in the case of hot runner, power supply wiring should be correct, cooling water to meet the design requirements, mold in the production of injection molding machine, die casting machine, press machine parameters and design requirements, etc.. In the correct use of the mold, the mold is also required to carry out regular maintenance, mold guide column, guide sleeve and other parts of the relative movement should often be filled with lubricating oil, for the forging mold, plastic mold, die casting mold and so on mold before each mold forming should be lubricants or molding agent spray on the surface of the formed parts.
With the development of society, more and more attention has been paid to the quality of molds. Quality is a new topic. Quality is improving with the improvement of mould technology.
