摘要： A washing apparatus of a screw for extruder including a casing, support rollers installed in the casing so as to support a screw rotatably, a drive motor for rotating the screw, a water jet assembly having a nozzle and nozzle rotation section, a nozzle inclination motor to incline the water jet assembly relative to the axis direction of the screw. A nozzle hole of the water jet assembly is inclined to face one way relative to the axis of the screw placed on support roller assemblies. The nozzle is rotated eccentrically about the nozzle hole and moved from one end to the other of the screw, changing the nozzle hole direction to the other way relative to the screw at the other end of the screw. The screw is rotated so that an unwashed part of the screw faces the nozzle and is washed. This cycle is repeated until the entire surface of the screw is rotated.

摘要： An apparatus comprising a resin plasticizing injection machine having an injection nozzle, a branch portion connected to the injection nozzle and having a plurality of outlet ports, molds and mold clamping devices both arranged around the branch portion in corresponding relation to the outlet ports, and an extension nozzle for maintaining each of the outlet ports in communication with each of the molds. Pressure control means is provided at an intermediate portion of the extension nozzle for maintaining the mold cavity at a specified pressure after resin has been injected into the mold. Means is provided for closing a flow channel extending from the injection machine to the pressure control means. After resin has been injected into a mold, the cavity of the mold can be maintained at the specified pressure by the pressure control means in place of the injection machine, so that the injection machine and the next mold can be subsequently brought into operation. Preferably resin is injected into one mold after another in succession in such a manner that the first mold is prepared for the injection of resin again before the injection machine is made ready for the injection into the first mold after completing the injection of resin into all the molds. The flow channel closing means comprises a shutoff valve mounted on each of the extension nozzles. The branch portion may comprise a branch valve for selectively opening or closing the flow channel.
摘要翻译：一种装置，包括具有注射喷嘴的树脂增塑注射机，连接到注射喷嘴的分支部分，并且具有多个出口，模具和模具夹紧装置，两者都以与出口对应的关系布置在分支部分周围;以及延伸喷嘴，用于保持每个出口与每个模具连通。压力控制装置设置在延伸喷嘴的中间部分处，用于在将树脂注射到模具中之后将模腔保持在特定的压力。提供了用于关闭从注射机延伸到压力控制装置的流动通道的装置。在将树脂注入模具之后，可以通过压力控制装置代替注射机将模具的空腔保持在规定的压力，从而可以随后使注塑机和下一个模具投入运行。优选地，将树脂连续地注入一个模具中，使得第一模具准备用于在注射机准备好用于注射到第一模具中之后再次注入树脂，从而将树脂注入所有的模具流道关闭装置包括安装在每个延伸喷嘴上的截止阀。分支部分可以包括用于选择性地打开或关闭流动通道的分支阀。
