摘要： The apparatus of the invention is an injection molding apparatus of a type adapted to cool a molten metal under shearing by an extrusion screw in a substantially vertical chamber into a semi-solidified slurry and then inject the semi-solidified slurry discharged from a discharge port at the lower end of a channel into molding plates, in which a clamping device is adapted to open or close a movable plate relative to a stationary plate in the horizontal direction, and a connection member having, at the inside, a vertical first channel and a second channel extending in the horizontal direction from the lower end of the first channel and in communication with the stationary plate is connected to the discharge port at the lower end of the chamber. Since this can inject and mold light metal molding products of high quality with less pore or shrinkage without excessively enlarging the size for the height of the apparatus, casting products of high quality can be obtained at a reduced cost by injection molding.

摘要： A polyester resin is thickened in a chamber 4 by first introducing the feed resin through a port 2 and dehydrating in a drying section 14 under reduced pressure. A chemical agent is then added to the dehydrated feed resin and mixed therewith in a thickening section 15. The mixing occurs while deaerating under reduced pressure. The chemical agent functions to either increase the viscosity of the feed resin or suppress the lowering thereof.

摘要： In the case of thickening a feed resin without pre-drying, a device is taught to enhance the thickening effect. The device includes a chamber 4 having a mixing rotor therein for continuously mixing a resin between a feed port 2 and a discharge port 3. A plurality of vent ports 7 connected to vacuum pumps 8, 9 are provided for reducing the pressure in the chamber. An element, e.g. a screw feeder 10, is provided for introducing a viscosity-increasing chemical agent into the chamber. The screw feeder is isolated from the reduced pressure areas of the chamber by elements 35, e.g. reverse screw flights of the rotor. In operation, feed resin from a hopper 6 enters the chamber through port 2 and is dehydrated while being continuously mixed in a drying section 14 via vents 7. After addition of the chemical agent, the resin is continuously mixed in a thickening section 15 while being deaerated.

摘要： A bladder for a vulcanizer includes, as a constituent member, a low elongation material with stable properties at vulcanization temperatures. During a vulcanization-molding process, the bladder is pressed against the inner surface of a green tire using a pressurized medium. The pressurized medium can be at vulcanization temperatures. The bladder has substantially the same shape as the inner wall surface of the tire that is formed using the bladder. As a result, irregularities in the shape of the inner wall surface of a tire rarely occur, and the frequency of exchange of bladders can be reduced. The vulcanizer bladder can include a conductive material or a magnetic material, both of which can be heated by using an induction heating coil. The use of both heat from the pressurized medium and heat generated in the bladder to vulcanize a green tire can shorten the period of time required for vulcanizing-molding.
摘要翻译： 用于硫化机的气囊包括在硫化温度下具有稳定性能的低伸长率材料作为构件。 在硫化成型过程中，使用加压介质将气囊压靠在生轮胎的内表面上。 加压介质可处于硫化温度。 气囊具有与使用气囊形成的轮胎的内壁表面基本相同的形状。 结果，轮胎的内壁面的形状的不规则性很少发生，可以降低气囊的交换频度。 硫化剂囊可以包括导电材料或磁性材料，它们都可以通过使用感应加热线圈加热。 使用来自加压介质的热量和在气囊中产生的热硫化生轮胎可以缩短硫化成型所需的时间。
