Mould manufacturing quality has a significant impact on the life of Daily Necessities Mould(FURNITUREMOULD), mainly in the following aspects. 1. The influence of mould parts processing precision. Geometrical shapes of working parts of daily necessities mould parts, such as fillet radius, draft angle and cutting edge angle, shall be processed strictly according to design requirements: when tools or equipment cannot be realized, manual grinding and strict measurement shall be carried out to ensure that the daily necessities mould has a reasonable stress state: for parts with matching dimensions, tolerance or matching grinding shall be ensured. 2. Influence of surface roughness of mould cavity. The reduction of surface roughness can reduce the flow resistance of the blank and the wear rate of the mould cavity on the one hand, and reduce the surface defects (such as tool marks, electro-machining molten spots, etc.) and the tendency to generate cracks on the other hand. Surface roughness has a great influence on the life of daily necessities mould. 3. The influence of daily necessities mould hardness uniformity. In the heat treatment process of daily necessities mould, uniform heating and cooling shall be ensured, oxidation and decarburization of the surfaces of daily necessities mould shall be prevented, and timely and sufficient tempering shall be carried out after quenching to improve the uniformity of hardness of daily necessities mould, thus obtaining good wear resistance, high fatigue resistance or high cold and hot fatigue life. 4. The influence of daily necessities mould assembly precision. The adjustment of the clearance and uniformity of daily necessities mould, the increase of the contact between the mating bearing surface and the mould closing surface, and the guarantee of the consistency of the stress centers of the male mould and the female mould can all improve the assembly accuracy of the moulds, thus improving the service life of daily necessities mould.
