Locating ring and sprue bushing are fixed in the fixed mold mounting plate by screws. Three ways when given template assembly height larger size can be used as shown in the way of the gate bushing assembly positioning ring and upcoming positioning ring fixed in the fixed mold mounting plate, which can shorten the length of the main road, so that the injection pressure losses to a minimum. Material used to pull the needle after the injection channel and product pull abs-130, it remains in the moving mold side or the fixed mold side. Work pull material commonly used in the processing of used needles are common dome needle, thimble usually processed into a special top shape. Anti-tilt pin puller is a common anti-tilt pull material needle, pull the top of the material to be processed into a tapered needle, to form undercut structure abs-223, so that the flow channel can hook. This structure does not apply to the hard plastic material, because the flow passage is not easily separated from the needle and pull the material, is not easily removed after the mold-opening flow channel. Cooling in the mold, cooled in different ways, the most common is by water cooling. In addition abs, but also through insulation panels cool. Typically abs plastic, heat transfer medium is water and oil. Design principles are described below mold cooling water of the most widely used in the cooling water, the first to introduce the precautions waterway design. Tips from the edge of the cavity is larger than the outer diameter of the waterway 1,001,111 is not to say the bigger the better. Generally, the farther away from the cavity waterway, the worse its cooling effect, if too close, they can not guarantee the strength of the mold, for controlling the distance between 10-20 is more reasonable. abs-212_ Taiyuan abs_ Gary Paffett trade provided by the Shenzhen Municipal Trade Co., Ltd.
