Abstract
The utility model relates to a drawing rod movement type device for mould closing for an injection moulding machine, which belongs to a plastic injection moulding machine. The utility model uses a structure that an adjusting template, a guide drawing rod and a movable template are simultaneously moved, the interior of the drawing rod is provided with an integrally movable oil cylinder, the adjusting template is connected with the movable template through a supercharging locking oil cylinder, and the interior of the supercharging locking oil cylinder is provided with a mould opening oil cylinder. The utility model solves the defects in the mould moving travel range aspect of an original mechanism, and the mould moving travel range and the mould containing size can be increased without increasing the integral size of a mould closing device. The utility model has the advantages of little material expenses, low cost, little occupation area and high complete machine performance.
Description
This device belongs to plant equipment, especially belongs to the injection molding machine.
The injection machine that uses is made of mold closing mechanism, injection moulding apparatus and fluid pressure drive device at present.Its mold closing mechanism is to be combined by four fixing guiding pull bars by fixed form, adjusting template and moving die plate, leans on the clamp nut at pull bar two ends to be tightened to one.Moving of moving die plate, be that the opening and closing mould is to realize by being connected the stretching motion of regulating the toggle link of cranking arm between template and the moving die plate, its shortcoming is the shifting formwork stroke toggle link size restrictions of being cranked arm, promptly along with the increase of product molding size and mold clamping force, generally crank arm toggle link, template size and stroke all will increase, and causes the mold closing mechanism volume of this structure excessive, wasted material, floor space is big, has increased manufacturing cost.
The purpose of this utility model is to provide a kind of novel injection machine mold closing mechanism, overcoming in the above-mentioned prior art shifting formwork stroke toggle link size restrictions of being cranked arm, and the mold closing mechanism volume is excessive, waste material, floor space is big, has increased weak points such as manufacturing cost.
For achieving the above object, the technical scheme that the utility model is taked is: a fixedly connected fixed form 9 on guide rail 12, moving die plate 2 slides on guide rail by shoes 7, one end of 4 guiding pull bars 3 is fastened on respectively to be regulated on the template 4, the guiding pull bar passes moving die plate and fixed form, slippage in the pilot sleeve 10 of guiding pull bar on fixed form, 4 open-close type locking flashboards 1 are installed on fixed form, whole mobile oil cylinder 8 is arranged in pull bar, one end of whole mobile oil cylinder is fixed on the bracket sleeve tube 11 that is installed on the fixed form, regulate between template and the moving die plate and link together with 4 supercharging locking cylinders 5, in the supercharging locking cylinder, also be provided with opening mold oil cylinder 6, one end of guiding pull bar 3 has locking tooth form 13, in the open-close type locking flashboard 1 corresponding locking tooth form 14 is arranged.The course of work of this device is as follows: at first by the whole mobile oil cylinder work in the guiding pull bar, driving adjusting template, guiding pull bar and moving die plate moves, the shoes of moving die plate and guide rail slide and realize that matched moulds puts in place, the work of the flashboard of open-close type locking simultaneously, the pull bar that will lead locking, matched moulds pressurizing cylinder work subsequently with mold-locked, realizes injection mo(u)lding; During mold open, at first be that open-close type locking flashboard unclamps, realize die sinking by the opening mold oil cylinder work that is built in the matched moulds pressurizing cylinder subsequently, behind the mold open by the mobile oil cylinder work of integral body, drive and regulate template, guiding pull bar, moving die plate and mould move simultaneously, and it is removed, and take out product and realize a working cycles.
Because adopting, the utility model regulates template, guiding pull bar and dirty moving platen moving structure simultaneously, can solve the shortcoming that original mechanism exists aspect the shifting formwork stroke, can realize the increase of shifting formwork stroke and product size and do not increase the overall dimensions such as toggle link size, template size of mold closing mechanism, can reduce Master Cost, save cost, reduce floor space, improve the complete machine performance.
Below in conjunction with the drawings and the specific embodiments the utility model is described in further detail.
