摘要： PROBLEM TO BE SOLVED: To provide a mold clamping mechanism and an injection molding apparatus capable of shortening a molding cycle of a resin molded article by miniaturizing a mechanism by removing a die plate for clamping from the mechanism and further accelerating speeds of clamping operation and de-clamping operation. SOLUTION: A connection part 93 of a shaft 33 is inserted into an inserting hole of a fixed die 14 according to the connection of a moving die 15 to the fixed die 14, and when the shaft 33 is rotated by only a predetermined angle accompanied by the movement of an air motor 83, the connection part 93 of the shaft 33 is connected to a connection part 102 formed at the inner peripheral surface of the inserting hole, and when a force in a drawing direction with respect to the inserting hole is charged to the shaft 33 in this state by supplying moving oil to an oil-pressing room 51 for the clamping of an oil pressing washer 32, the shaft 33 is elongated to its axis direction, whereby the moving die 15 is connected by pressure to the fixed die 14 by an axial force generated in the shaft 33.

摘要： PROBLEM TO BE SOLVED: To maintain a stable molding operation over a long period in a vertical injection molding machine. SOLUTION: The vertical injection molding machine includes a plurality of weights 10 each connected to a movable body 4 through a wire 24, the wire 24 being laid around a pulley 16. Since the total weight of the plurality of weights 10 is equal to the weight of the movable body 4, the plurality of weights 10 is regularly balanced with the movable body 4 with the pulley 16 as a fulcrum. The plurality of weights 10 is provided and these weights are dispersively arranged in this way, whereby the stress caused by the weight of the movable body 4 applied to each wire 24 and each pulley 16 around which the wire 24 is laid is dispersed. Therefore, even when the movable body 4 is repetitively vertically moved, the movable body 4 can be smoothly raised and lowered while suppressing the elongation of each wire 24 and the deformation of each pulley 16. Consequently, the stable molding operation of the vertical injection molding machine 1 can be maintained over a long period. COPYRIGHT: (C)2010,JPO&INPIT
摘要翻译：要解决的问题：在垂直注射成型机中长期保持稳定的成型操作。解决方案：垂直注射成型机包括多个重物10，每个重物10通过线24连接到可移动体4，线24围绕皮带轮16布置。由于多个重物10的总重量相等相对于可动体4的重量，多个重物10以滑轮16为支点与可移动体4规则地平衡。设置多个重物10，并且这些重量以这种方式分散布置，由此施加到每个线24和布置有线24的每个滑轮16的可移动体4的重量所引起的应力被分散。因此，即使在可动体4反复垂直移动的同时，也可以平滑地使可移动体4升高和降低，同时抑制每个线24的伸长和每个滑轮16的变形。因此，垂直注射成型机器1可以长时间保持。版权所有（C）2010，JPO＆INPIT
