Mold products are not the same, due to both injection molding, die casting type of high temperature flow molding or room temperature stamping type of plastic molding, despite the long decades of research and application history, due to the basic theory and mathematical model is very imperfect, inaccurate, there is still a great deal of uncertainty, especially in our country, most of them still rely on the field debugging experience to support to make as much as possible! Mold products to do perfect, produced to meet the user user requirements, so in the design stage, most of the current can only do the work in the entire mold manufacturing process and quality system link to ensure that kind, can only act as a "roughing link"! That is, the mold is usually said to be good or bad ultimately rely on the clamp craft, different manufacturers of mold products, the final summit showdown, may be a mold clamp a skill competition, and in this line of designers and pre-processors can only be to the summit showdown to do the supporting role.
I don't know, I didn't say, the majority of peers agree, but it is true, and then the perfect mold design, and then good drawings, and then expensive equipment, for the time being, ultimately have to mold clamping to speak in front of the labor of a few people and the wisdom of embodied out of the absence of them, I'm afraid that our design is a pile of scrap metal!
Additionally, at present, we then mold structure, especially the more complex mechanical structure (such as automotive molds in a variety of slanting wedge linkage mechanism) research efforts seem to be not deep enough, and there is no some of the international leading technology or even patents, advanced, complex structures are still mainly to refer to foreign precedents to design, independent research and development level is relatively weak, on the contrary, the clampers! Re-assembly, debugging the level of these institutions may be better than abroad.
As mentioned earlier, the theory of plastic molding and mathematical mold shape is not perfect, resulting in the stamping process analysis and development of the design stage is not perfect, the need for a large number of clampers later debugging, this problem may be a moment of time may not have immediate solution for the designers can still be appropriate to shirk the responsibility of the reason, but the level of mold mechanical structure of this is not good for the kind of "hard", it seems that we have to take into account the level of the mold mechanical structure of this is not good for the kind of "hard". Hard", we seem to be a little difficult to resign their guilt, of course, I think this is also caused by a variety of reasons.
First of all, the higher-end mold mechanical structure is usually only applied to more complex parts and processes, such as the car's side panels, wing panels, the hood of the press fit and other parts, the domestic car manufacturers due to more Sino-foreign joint ventures, it is difficult to do so that the domestic mold enterprises to manufacture molds for these products, the new model of the similar parts is even more to talk about a few, so we have few combat opportunities. Few opportunities, part of the strength of the manufacturers may be less in the production task is to practice the theoretical design, the final effect of God knows that people do not know!
Secondly, even if the opportunity to meet this difficult, most manufacturers may search the bowels of the oligo-du, a thousand put a hundred ways to look for foreign original drawings, and then only to design the final mechanical structure, there may be some improvements and refinements, into a mold products with Chinese characteristics, and can even be exported to these countries, but ultimately it is difficult to hit the real "! MADE IN CHINA" brand, the foreign map, China's steel, put together with the heart does not panic, huh
So, our mold industry, whether from the design of R & D or machining, there is a lack of original and independent technology inherent defects, only innate advantage may be the ancestors "casting and forging the sword". The only inherent advantage may be the old ancestors "casting tripod forging sword" of the evolution of superior craftsmanship out of the current mold clamp peak craftsmanship, the day of the World Mold Clamping Competition, our players to win the championship call may be higher than the call of Abenomics stepping down, the first battle with me, with me will win!
