DFM. No, not Designed for Manufacturability, Designed for Maintainability. Every mechanical apparatus will eventually need maintenance; it’s a fact of life. Knowing this should be all the impetus needed to motivate anyone with a vested interest to give more than just passing thought to the design of injection mold tooling. The understanding that tools will [...]
Standard slide assemblies have been available to molders and moldmakers since 1991. The design and production of a standard component is critical to the success of the product. Not only does the design have to be very reliable and proven, it also has to be versatile enough to fit many different applications. That is the [...]
shallow side concave of plastic parts requires small core-pulling distance, yet when the molding area of side concave is large, a large core-pulling force is thereby needed, therefore, tilted lifter mechanism can be adopted for side parting and core-pulling. […]
a detail for designing tilted lifter mechanism need to be known, for inner side core-pulling, top of the tilted slide should be 0.05—0.1mm lower than the end plate if core, since during the protruding, […]
a suitable dip angle for designing a tilted lifter mechanism is very important, I think the pin’s dip angle B should be taken 5—25 degree ， […]
I have a tip for designing a tilted lifter mechanism, to endow the mechanism with restoration function, the length of circular bead for restoration should be adopted preferably larger under possible conditions, […]
in first-rate mold solution co, ltd, our designer often design an angle pin core-pulling mechanism, […]
The core should be set preferably in the moving or fixed mold vertical against the parting line so that the side core can be pulled out through mold opening or the pulling action.
Use preferably core-pulling mechanism wherein the angle pin is located in the fixed mold and the slide in the moving mold.
Wedge angle of the wedge block should be larger than the obliquity of angle pin, usually larger than 2—3 degrees; otherwise, the angle pin can not drive the slide.
