Description
Technical field
System of the present invention, about a kind of forming machine clamping apparatus, is espespecially used on plastic injection machine or Die casting machine, for clamping or the locked mode clamping device of liberating brother woods post.
Background technology
The clamp force of forming machine is one of factor of impact injection finished product accuracy, and general known common locked mode clamping device, refer to the Republic of China and announce No. M481124 " can huge pillar depart from Jet forming machine " patent, it is that exposure has tool left, the mode locking cylinder of right grip block, and in grip block, be formed with tooth portion, be positioned at a left side for mode locking cylinder, mould-locking large-column is equipped with in right grip block, and this mould-locking large-column is provided with the thread corresponding with tooth portion, by this, can in active mould seat after mould-locking large-column top offset, being meshed with the tooth portion of relevant position through making the thread of mould-locking large-column allows active mould seat be fixed on locked mode position, but, if clamp force is less than mould cavity pressure, mould will be made to produce gap, cause injection finished product flaw, if clamp force is excessive, huge pillar can be caused again to bend or make template deformation.
For improving above-mentioned disappearance, therefore the Republic of China announces M369848 patent, system discloses a kind of " double-template mould-clamping mechanism ", it lies on moving platen and establishes clamping and positioning device, and make clamping and positioning device be sheathed on outside pillar, and outside moving platen, establish high-voltage lock mould cylinder, be positioned at high-voltage lock mould cylinder one end and be provided with half nut supplying clamp posts, this half nut has tooth portion and is provided with clamping validator in one end, to confirm pillar and half position of engagement, nut tooth portion, in addition, mode transfer gear is provided with in quiet template lower end, and nut is engaged mutually before making mode transfer gear and motor and being located at quiet template corner, by this, can before locked mode, moving platen is measured through clamping validator, and allow motor start drive mode transfer gear to make it rotate again nut before interlock, pillar is made to carry out trimming movement between mode transfer original position and mode transfer extreme position, until clamping validator confirms that the tooth portion of pillar upper tooth portion and half nut is apposition, the time consumed is corrected to reduce mode transfer.
Separately, the Republic of China announces M396752 patent, system discloses a kind of " clamping apparatus of plastic injection machine ", it is that active mould seat and fixing die holder have placed guide rod, this guide rod has the tooth section of stiff end and tool plural number latch, mark of mouth is formed between each latch, be positioned at active mould seat and be provided with the positioning body placed for guide rod, this positioning body has a draw-in groove, draw-in groove cell wall forms plural card convex, card is formed with recessed between each card convex, and be provided with positioning unit in active mould seat, this positioning unit interlock has trip, and in trip week side be provided with correspondence and fasten mark of mouth and block recessed protuberance, by this, can in time carrying out locked mode operation, control positioning unit start, cylinder pressure is made to drive trip and fasten between guide rod and positioning body, now, the protuberance of trip can correspond to the mark of mouth of the recessed and guide rod of the card of positioning body, make it produce oblique contract to do in order to complete locked mode operation.
But, through arranging tooth portion respectively or tooth section makes it engage and the mode making active mould seat fixing, still may produce backlash because just in time the position of engagement cannot be positioned between tooth portion or tooth section, and then the excessive or not enough situation of clamp force occurs.
