plastic die manufacturing precision is an important factor affecting the drawing die 123
plastic die manufacturing, the precision of the blank surface for the impact of the drawing die is very important. When the die is put into mass production, the tightness of the pressing surface directly affects the quality of the part and the service life of the die. If the pressing surface is too tight, it will lead to increased friction and Burr, and if the pressing surface is too loose, the binding force of the sheet is not enough, it is easy to appear the polymer phenomenon, which directly affects the service life of the die
Plastic mold plays a key role in the production of parts, in which the precision of the blank holder has an important impact on the performance of the mold. In general, grinding the pressing surface to the proper state can significantly increase the processing speed. However, in the process of die debugging, there may be a problem that the pressing surface is not easy to color, mainly because of the grinding equipment pressure is too large. The pressure during debugging and grinding is not the same, the use of air cushion may not be able to achieve the pre-set pressure value, resulting in pressure surface sometimes loose and sometimes too tight situation
In order to solve this problem, usually use air-cushion grinding method, and with the appropriate balance block. Confirm the colouring of the pressing surface and balance block by rubbing to ensure even colouring of the pressing surface and complete grinding of the raw material. In mass production, in order to avoid Burr or polymer parts, should be used as far as possible the smallest pressure, to avoid mold damage caused by failure to meet the standard
In general, the precision of the blank holder is an important factor that affects the quality and service life of the drawing die. Through proper grinding method and pressure control, it can ensure the good colouring and grinding effect of the pressing material surface, and improve the production efficiency and product quality of the die. In actual production, it is necessary to pay attention to the adjustment and maintenance of the pressing surface to ensure the long-term stable operation of the die.
