Definition of injection mold: plastic injection machine injection machine injection non-standard tools after cooling molding tools called molds, precision injection mold in the design will appear in a variety of problems, the following is for a variety of problems corresponding to the solution：
Problem 1: The determination of the structure of precision plastic molds is crucial, and the overall structure is a reflection of the final effect of the product. The determination of the overall structure of the mold, the determination of the water inlet system, the determination of the ejection system, and the determination of the water delivery system should be conducive to the post-processing orientation of the product.
Question 2: Water entry problem? 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 arrangement should be uniform, b the size of the transverse load surface of the main diversion channel, and c the shape and size of the rubber mouth.
Question 3: Is there a problem? 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 four: The design of the water transport system is based on four 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.
Problem 5: How to ensure the machining accuracy of the mold, the accuracy of the product, mainly depends on the accuracy of the mold cavity, the inlet and the mold core size, the accuracy of the cavity positioning or the accuracy of the parting surface will directly affect the size of the product;
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;
b After the completion of processing, the workpiece should be processed and maintained.
