The sheet structure and form of injection mold are introduced

Of course, the mold can be made at a lower cost when the number of injection mold plate structure is small. The use of injection mold and mold accuracy should be considered to determine the structural composition of the plate. One of the main factors that determines the structure of the injection mold is the structure of the plate. The structure of the plate has much to do with the production method of the main plate of the injection mold.

When the punch is large, some injection molds omit the punch fixing plate and upper die seat, and install the die handle directly on the punch. At this time, the plate structure is composed of three pieces, such as discharge plate, die fixing plate and lower die seat. Bending die and so on sometimes do not need discharge plate, only 2 pieces of structure. However, such a plate structure is more special, usually used on the basis of 5 pieces to increase the number of indefinite structure. The indefinite number of parts is the backing plate.

The maximum number of the injection mold plate is 8 pieces (excluding composite die and simple wood die, etc.) The basic structure includes 5 pieces: (1) upper die base (2) punch fixing plate (3) discharge plate (4) concave die fixing plate (5) lower die base. Insert type Because other parts (insert parts) are installed in the plate, it is necessary to fix and support the insert, so the backing plate is needed.

The main function of the injection mold pad is to support punch, etc., but it is also sometimes used to fix inserts, adjust height level, and occasionally as a bottom punch plate. A major factor in determining whether or not you need a backing plate is the form of the plate. Integral, trough and yoke, as shown in the figure, do not need a backing plate. Of these three types, more recent use of integral. The other two are rarely used. The mission of Fanstar is to master the core technology of injection molding production, communicate and analyze the technology before mold production with customers from the production needs of finished products, so that the mold delivery time is short, the life is long, the mass production is fast and the finished product quality is excellent!
