How to choose the mold base before injection mold making? The choice of mold base depends on the characteristics of the product and the number of injection mold cavities. Two-plate molds, simplified three-plate molds, and standard three-plate molds are common mold base specifications.
How to choose the mold base before injection mold making?
①According to the structure of the injection mold, it is selected to meet the mold forming purpose and the requirements of the customer’s specified mold base. If the two-plate mold can be used, the three-plate mold is not used because the two-plate mold has a simple structure and low manufacturing cost.
②The standard mold base is preferred. The standard mold base is not suitable for all, you can customize it according to your own size. The three-plate mold base is suitable when the product uses point gates. The two-platen mold base is suitable for hot runner molds.
③The selected mold base should be suitable for the technical parameters of the injection molding machine, can meet the closed height requirements of the injection mold, and meet the ejection stroke and ejection mode in the mold opening stroke. The shape size should be less than 5mm between the column spacing of the injection molding machine. Under the premise of ensuring sufficient strength and rigidity of the mold, the size should be small but not large. The shape is limited by the injection molding machine, and a straight mold is used.
④The standard mold base adopts the insert structure, and the manufacturer is required to process the size of the insert frame on the mold base, or leave a 25mm machining allowance to prevent deformation
⑤The standard three-platen mold should be used as far as possible for injection molds with high requirements and long life.
