There is provided a barrel support apparatus of an injection apparatus which can effectively reduce bending of the barrel due to its own weight. According to one embodiment of the present invention, a barrel support apparatus includes: a barrel support member for supporting a barrel from below; and a leg portion which supports the barrel support member, and can move following the forward and backward movement of the barrel.

Barrel support apparatus and injection apparatus

A movable platen according to the present invention includes: a mold clamping platenhaving a projecting portionin a mold closing direction-side surface; a mold mounting platenmounted to the projecting portionof the mold clamping platen; and a guide mechanismfixed to the mold clamping platenand supporting the mold mounting platen. Only the mold clamping platenis fixed to the guide mechanism, while the mold mounting platenis not fixed but placed on platen surface support portions

Opening/closing apparatus and molding apparatus comprising the same

Movable platen, opening/closing apparatus and molding apparatus

The present invention provides a movable platen support apparatus which, with a linear guide having a minimum necessary load rating, can secure a sufficient traveling life of the linear guide and, in addition, can secure the rigidity of the linear guide which is necessary and sufficient taking into consideration a moment that acts on a movable platen. A movable platen support apparatusaccording to the present invention includes a guide mechanism which movably engages a railextending on a framein the direction of movement of a movable platen, to which a movable moldis to be mounted, and which movably supports the movable platen. The guide mechanism includes a linear guidecomposed of blockstoarranged in a line, in which at least one of the blocksto, e.g. the blocks, has a load rating which differs from the load rating(s) of the other block(s), e.g. the blocks

Movable platen support apparatus, movable platen, mold opening/closing apparatus and molding apparatus

An opening/closing apparatus is provided for use in a molding apparatus, such as an injection molding machine. The opening/closing apparatus may eliminate the influence of a slight gap formed between a bush and a pin in a link connecting portion of a toggle link mechanism and in addition, can enhance workability e.g., in mold replacement. An opening/closing apparatus of the present technology may include an opening/closing mechanism including a toggle link mechanism connecting a pressure-receiving platen and a movable platen; a drive mechanism for driving the opening/closing mechanism; and a core-back hydraulic cylinder for applying a load to the movable platen in a given direction in conjunction with the first drive mechanism, configured to perform the operation of slightly opening of the mold.
