Injection mold die set before making how to choose
injection mold die set before making how to choose? Choose what kind of die set depends on the products and the characteristics of injection mold cavity number, junior model, simplified type three board model, standard three board mould is a common mould specification. Injection mold die set before making how to choose? (1) according to the structure of injection mold, molding purpose and standard to choose to die set specified by the customer requirement, can use junior die, do not use three board mould, because junior mold structure is simple, the manufacturing cost is low (2) priority selection standard mould base. Standard mould base is not suitable for all, can be customized according to your own size. Three board mold die set for when the products adopt point gate. Junior mold die set is suitable for hot runner mold. (3) the selection of formwork should be suitable for the technical parameters of injection molding machine, can satisfy the requirement of the injection mould height, meet at the top of the mould stroke of the ejector stroke and out of the way. Dimension to less than 5 mm, injection molding machine column spacing in guarantee under the premise of mould have sufficient strength and rigidity, size should be small not big for straight mode with the selection of type, usually three board mould choose labor type frame, usually die because of the appearance is subject to the conditions of injection molding machine, and adopts straight model. (4) the set piece of structure of standard mould frame, require manufacturers to mould frame framed machining dimension, or have 25 mm machining allowance, in case of deformation (5) high demands, high life of injection mold adopts standard three board model as far as possible.
what is the effect of injection mould test times will
1, the injection mold design has not been fully collective review, injection mold structure is unreasonable, make injection mold after test after many improvements, even make injection mold cost over budget. If after several improvement, can be done, that is lucky, there are a lot of cases are not satisfied, even injection mould be discarded to do, the cost will not be able to control. And some are plastic injection mold design is very good, but the injection mold processing does not reach the designated position, make irrational increase test frequency, increasing the injection mold cost directly. This problem is no objections, so a lot of injection mold manufacturers have stepped up measuring equipment.
2, test without choice model of molding process and injection molding machine, injection mould do obviously very well, but the injection molding of products is not ideal. Endless increased the test number, increasing the injection mold cost directly. This is the common fault of the small injection mold factory.
3, understanding of the physical properties of the plastic is not fully, even shrinkage rate are not accurate, the situation is often happened. So, in the design of injection mold before they can be sure to clear plastic physical properties, can effectively reduce test times.
