【正文】 英文翻譯 Gating system design forms and gate A. mainstream design 1. Mainstream Road Size Road end and mainstream is in contact with the nozzle injection machine, and the other end of shunt connected with the taper section of the mobile channel. Road mainstream Xiaoduan size of ~ 4 mm. 2. Hub in the form of mainstream Road Road entrance to the mainstream Xiaoduan and repeated contact with the nozzle injection machine, is a consumable, more stringent requirements of the material, thus, part of the mainstream mold often designed as a removable sleeve, the replacement of the mainstream form (monly known as the gate sets, said here Jack Tsui), in order to effectively separate the selection of highquality steel processing and heat treatment. Jack Tsui are standard parts, just to buy on the line. Common jack Tsui into a jack Aguilar asked not care jack Tsui and two under the former map, a jack Aguilar asked for patibility positioning circle. Jack Tsui specifications are Φ12, Φ16, Φ20, such as several. As for the injection nozzles a radius of 20, so jack Tsui for R21. 3. Mainstream, the fixed hub Because the use of a child care jack Tsui, using circle with a fixed location in the mold of the panel. Setting circles are also standard parts, the diameter of Φ120 mm, diameter Φ35 mm. Specific institutional form as shown below: B. shunt design In multicavity or multicavity gate (plastic pieces of large size) should be set up triage Road, shunt is the mainstream, with the gate between the end of this section of the plastic melt flow channel. It is pouring in molten state system of plastic into the cavity from the mainstream Road, through the crosssectional area and the changes in the flow of transformation for the smooth transition of the flow pattern. Therefore, should be designed to divert the pressure to meet a good transfer and maintain the ideal state of filling and in the process of movement of pressure loss as possible, can melt plastic balanced distribution to the various cavity. 1. Main shunt the shape and size Road map is the main streaming (6) in the intake level of underflow. In order to facilitate the processing and condensate expected Stripping, shunt installed in most of subsurface, the shunt is generally circular cross section trapezoidal shape of Ushaped semicircular and rectangular, engineering design often used trapezoidal crosssection processing technology is good, and the plastic melting The loss of heat flow resistance are not large, generally using the following formula to determine their experience section size: Type Bladder in the bottom edge of the width (mm) mweight plastic parts (g) Lsegregation, the length (mm) Hladder height (mm) The bevel side of a ladder often take 50150, in the application of (1) should pay attention to its scope of application, that is, plastic parts in the thickness of mm below the weight of less tha
