Mould quality includes the following aspects:
(1) product quality: product size stability, conformity, product surface finish, product material utilisation and so on;
(2) service life: under the premise of ensuring the quality of products, moulds can complete the number of work cycles or the number of pieces produced;
(3) the use of mould maintenance: whether it is the most convenient to use, easy to take off the mould, the production of auxiliary time as short as possible;
(4) maintenance costs, maintenance cycle and so on.
The basic way to improve the quality of the mould: mould design is to improve the quality of the mould is the most important step, need to take into account a lot of factors, including the selection of mould materials, mould structure can be used and safety, mould parts can be processed and mould maintenance convenience, these in the beginning of the design should try to take into account the thoroughness of some. Mould manufacturing process is also to ensure the quality of the mould is an important part of the mould manufacturing process of processing methods and processing accuracy will also affect the service life of the mould. The precision of each part directly affects the overall assembly of the mould, in addition to the impact of the precision of the equipment itself, it is necessary to improve the processing of parts through the improvement of the processing method, improve the technical level of the clampers in the process of mould grinding and matching to improve the precision of the processing of mould parts. The main forming parts of the mould surface strengthening, in order to improve the surface wear resistance of mould parts, so as to better improve the quality of the mould. The correct use and maintenance of the mould is also a major factor in improving the quality of the mould.
For example: the mould should be properly installed and commissioned, in the case of hot runner, the power supply wiring should be correct, the cooling water circuit to meet the design requirements, the mould in the production of injection moulding machine, die-casting machine, the parameters of the press need to be consistent with the design requirements and so on. In the correct use of the mould, also need to carry out regular maintenance of the mould, mould guide pillar, guide sleeve and other relative motion parts should be frequently filled with lubricant, for forging mould, plastic mould, die-casting mould moulds and so on moulds in each mould forming should be lubricant or starting agent spray on the surface of the forming parts.
With the development of society, the quality of the mould is more and more attention, with the design, manufacturing mould degree of strengthening, mould new technology to achieve, mould quality by more and more attention. Quality is a topic that is often said to be new, and the quality is improving with the improvement of mould technology.
