Solutions for various problems in the use of precision plastic molds
Definition of precision plastic mold: plastic injection machine into non-standard tools after cooling molding tools called molds, use process and design process there will always be a variety of problems, the following is for a variety of problems corresponding to the solution:
Problem 1: The structure of the precision plastic mold is the key, and the overall structure is related to the final effect of the product: the overall structure of the mold is determined, the water entry system is determined, the ejection system is determined, and the water transport system is determined, which should be conducive to the post-processing orientation of the product.
Question 2: The water problem of precision plastic mold? First of all, we will choose a reasonable water entry program according to the structure, weight, volume and cost of the product, which can meet the requirements of customers and meet the requirements of quality. Secondly, it is strictly designed in accordance with the water entry design standards: a water outlet layout should be uniform in the size of the transverse load of the main diversion channel c shape and size of the rubber mouth.
Question 3: Ejection problem of precision plastic mold? First, we will determine the ejection method according to the orientation and binding of the product, and then we will evaluate the ejection balance and problems with other systems, such as interference with water transport and environmental labeling.
Problem 4: The design of the water transport system of the precision plastic mold is based on four major requirements (a water transport line as balanced as possible. b The lines carrying water must not interfere with other institutions. c Water transport equipment to meet customer standards as much as possible and easy to install. d Each water transport line should be displayed with an entry and exit sign.
Question 5: How to ensure the processing accuracy of plastic molds and the accuracy of products mainly depend on the accuracy of mold cavity, inlet and mold core size. The accuracy of cavity positioning or the accuracy of parting surface will directly affect the size of products; a First of all to develop the process flow table; b Each process must be fully inspected and a list of data testing in text form; c After the completion of processing, the workpiece should be processed and maintained.
