Problems solved by technology

[0003] However, the plastic fresh-keeping box injection molding surface finishing processing method in the current market has the following problems in the operation process: a. Since the bottom molding section of the plastic fresh-keeping box is a house type, when processing the bottom sprue end, it is necessary to equip Matching grinding heads or cutting blades are processed, so that each type of grinding head or cutting blade is only suitable for the processing of one type of plastic crisper, resulting in a narrow scope of application; b. Common plastic crisper injection molding surface In the finishing processing method, the cutting action and the grinding action are carried out relatively independently, resulting in cumbersome processing methods and low processing efficiency. At the same time, the traditional cutting and grinding methods are prone to damage to the cutting blade and grinding head during long-term operation. , affecting the quality of processing
