Description
Technical field
The present invention relates to a kind of clamping, specifically relate to the parallel clamping of single cylinder of a kind of footwear injection (mo(u)lding) machine.
Background technology
Clamping is the critical piece of injection (mo(u)lding) machine, has been the key device of process of injection molding.In current shoe-making industry; clamping form for injection (mo(u)lding) machine is a lot; and the parallel clamping conventionally adopting in " disc type footwear are with drawing side injection (mo(u)lding) machine " is the parallel clamping of twin-tub, it is to drive respectively the framed opening and closing mould that completes of the right and left to move by two hydraulic jacks.In actual use, this parallel clamping being driven by twin-tub has the following disadvantages:
The one, opening mould assembling action can not Complete Synchronization.In driving process, all there is error in the damping producing due to two oil cylinders in left and right and the processing of associated components, and Complete Synchronization can not be accomplished in completing out mould assembling action by Shi Gai mechanism, thereby causes the framed action of the right and left synchronously not carry out.
The 2nd, easy mold damage, and product quality can not be guaranteed.In matched moulds process, asynchronous due to the framed action in left and right, easily produces clamping phenomenon, causes article of footwear to occur folder nation, affects quality and attractive in appearance.And in die sinking process, also can be due to the framed action in left and right asynchronous, while causing die sinking to carry shoe last or hat block, the quality of easy damaged shoe tree and article of footwear.
The 3rd, regulate difficulty, waste time and energy.When the desired size of folding mould according to produce need to change time, need to separately debug the framed of the right and left, make it reach as far as possible synchronous effect, therefore regulate expend time in length and poor effect.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, and provide a kind of simple in structure, open mould assembling action Complete Synchronization, can mold damage, good product quality, and regulate and be easy to the parallel clamping of single cylinder.
The object of the present invention is achieved like this: the parallel clamping of a kind of single cylinder; comprise the oil cylinder connection seat being fixed in injection (mo(u)lding) machine frame and be fixed in the folding mould oil cylinder on oil cylinder connection seat; it is characterized in that: the piston rod front end of described folding mould oil cylinder is connected with push arm by screw rod; the both sides of push arm are respectively arranged with guide rod; two ends are connected with one end of connecting rod respectively; the other end of connecting rod is connected with one end of push rod; the centre of push rod and the other end are connected with respectively toggle link, and the two ends of toggle link are connected with framed assembly respectively.
The middle part of described push arm is provided with screw hole, both sides are provided with guide rod hole, two ends are provided with pin shaft hole, the piston rod front end of one end of described screw rod and folding mould oil cylinder is affixed, the other end inserts screw hole, and fixing with it by nut, one end of described guide rod and oil cylinder connection seat are affixed, and the other end inserts guide rod hole tangent with it.
Described toggle link is divided into short toggle link and long toggle link, and one end of short toggle link and long toggle link is hinged with framed assembly respectively, and the other end is simultaneously hinged with push rod.
Described framed assembly comprises rear base, rear base pressing plate, front base, front base pressing plate and framed, rear base, front base are fixed in by vertical columns in the frame of injection (mo(u)lding) machine, rear base pressing plate, front base pressing plate are fixed in respectively on rear base, front base and form slideway, framed being arranged in slideway.
It is described that framed to be divided into the left side being oppositely arranged framed and right framed.
One end of described short toggle link and the vertical columns of framed assembly are hinged, and one end of long toggle link is framed and right framed hinged with a left side for framed assembly respectively.
Described guide rod, connecting rod, push rod and toggle link is all symmetrical arranged with the horizontal center line of folding mould oil cylinder and framed assembly.
The course of work of the present invention is such: in the time that folding mould oil cylinder moves right, promotion push arm moves right, push arm does rectilinear motion to the right under the orientation of guide rod, and promote connecting rod and push rod moves right, drive short toggle link and long toggle link to right rotation, thereby promote left and right framed in slideway up and down both sides open, formed die sinking action.Otherwise when folding mould oil cylinder is during to left movement, above-mentioned member is moved to the left, left and right framed closure completes mould assembling action.
Compared with prior art, advantage of the present invention is:
1, open mould assembling action synchronous.What the present invention adopted is single cylinder drive form, and push arm is under the orientation of left and right guide rod, and the left and right toggle link of push-and-pull simultaneously drives the left and right framed opening and closing mould action of doing.Therefore, opening mould assembling action can Complete Synchronization, and stable.
2, can mold damage and guarantee product quality.The present invention opens mould assembling action Complete Synchronization, can in shoemaking process, complete out mould assembling action in time, makes mould article of footwear Bu Jia nation in the time of matched moulds bottoming, avoids shoe last by collsion damage, thereby ensured product quality when shoe last or hat block is carried in die sinking, has also extended die life.
3, be simple and easy to tune, time saving and energy saving.When the desired size of folding mould according to produce need to change time, only need to unclamp the clamp nut on screw rod, regulate the distance of tailpiece of the piston rod and the push arm of folding mould oil cylinder, then by clamp nut locking, be simple and easy to tune, time saving and energy saving.
