1.
Among tablet products should not be commonly into rubber, in order to prevent the bending deformation.
2。 In general, the STP in RP directly.
3。 When the mold base is bigger, the interval of the STP is 150 - 200mm。
4。 Lock up and down the ejector plate screw spacing is 150 - 200mm。
5。 When have a thimble at the bottom of the slide block, ejector plate up and down to a forced return.
6。 The finished draft Angle to reduce glue as a benchmark.
7。 SP as far as possible to take big the diameter and arrangement in the finished product of orthographic projection area below.
8。 Cooling impinges three principles: fast cooling, die temperature, processing is convenient.
9。 From the center of mold pin should be integer.
10。 For two and a half piece mold, parting between the fixed plate and the motherboard on schedule with institutional control, LP on male template must have a guide bushing, require a LK shutter is generally good.
11。 To deal with the method of the medial barbed pin, inner side sliding block, is commonly used in plate peeling, ejector pin should avoid as far as possible under the slider, so as to avoid collision or interference.
12. General cavities beyond 20 - finished product contour 30 mm, and from the center of mould should be integer, template 20 - from cavities border 30 mm, if you have the slider should consider the template, the return pin and pay special attention to avoid interference.
13。 Support put pads spacing should be equal, make the mold balance.
