The design of the diverter :
The diversion channel is the channel between the main channel and
the gate, which is generally opened on the parting surface and
plays the role of diversion and steering. The shape of the shunt section can be round, semicircular,
rectangular, trapezoid and U shape, etc., round and square section The specific area of the flow channel is the smallest (the ratio of
the surface area of the flow channel to the volume is called the
specific surface area) at the temperature of the plastic melt The drop is small, the resistance is small, and the flow channel
efficiency is the highest. But the processing is difficult, and the
square section is not easy to release, so in The section shapes commonly used in actual production are
trapezoid, semicircle and U shape. Key points of diverter design: (1) Under the premise of ensuring sufficient injection pressure so
that the plastic melt can be successfully filled with the cavity,
the diverter is cut The area and length should be as small as possible, and the turning
point of the diversion channel should be excessive with an arc. (2) When the diverter is long, a cold feed well should be set up at
the end of the diverter. For this model it's on the diversion path No need to open a cold feed well. (3) The position of the diverter can be opened separately on the
fixed template or on the moving template, or it can be opened
simultaneously on the moving template. On the fixed template, the cross section shape of the diverter is
formed after the mold is closed. (4) The connection between the diverter and the gate should be
processed into a bevel, and the arc should be excessive. 1) The length of the diverter The length of the diverter depends on the overall layout of the
mold cavity and the location of the gate, and is reduced from the
transfer of molten material The requirements for less pressure loss, heat loss and reduced
runner condensate should be shortened.
