Description
The present invention relates to a kind of two mould locking device, relate in particular to a kind of clamping apparatus that supplies injection machine and die casting machine to use.
The clamping apparatus that injection machine and die casting machine are used, one type is mechanical hydraulic-pressure type, another kind of type is a full hydraulic.But no matter the clamping apparatus of that type all requires high speed die sinking and matched moulds, reduce the conversion of action, to shorten molding cycle, enhance productivity, requiring again has big clamp force, and enough force intensitys that is subjected to are resisted the required briquetting pressure of goods.For many requirements above satisfying, the clamping apparatus of various kinds is all generally complicated now.Announced a kind of " the differential clamping mechanism of direct press type two template multi-cylinders " on the utility model patent communique, its public number is CN86204016U; The deficiency point of this patent shows as: first, the axial length of Mode-locking oil cylinder is longer, is difficult to processing and manufacturing, the particularly oil sealing of oil cylinder wearing and tearing easily in the opening and closing mold process of long distance, make to cause and leakage of oil occurs, occur the plastic products waste product easily up to influencing the stable of clamp force.The second, the slender holes in the Mode-locking oil cylinder more is difficult to processing, and sealing is poor, and is inner once seepage hydraulic oil occurs, and locked mode, die sinking, differential action are just inaccurate, influence product molding.The 3rd, owing to adopt the differential locked mode of multi-cylinder, seal is many, is easy to generate leakage of oil, and hydraulic valve piece is many, and the action conversion is many, the processing and manufacturing complexity, and the product molding cycle is long, and energy consumption is many.
The purpose of this invention is to provide a kind of high-performance, high efficiency, consumptive material is few, and is simple in structure, easily manufactured, lightweight, the two mould locking device of cheapization.
In order to achieve the above object, the present invention has two kinds of technical schemes;
A kind of scheme is:
On its frame, be fixed with fixed form and guide rail, on fixed form, be provided with fixed mould and folding mould oil cylinder; The piston rod of folding mould oil cylinder is connected with moving die plate; The push rod that moving die plate is provided with moving mold and mould is ejected also is fixed with long leading truck under moving die plate, long leading truck places on the guide rail, it is characterized in that: also be provided with pull bar on fixed form, also be fixed with a skewback on pull bar; The position of corresponding pull bar has the hole that pull bar can pass on moving die plate, be positioned on the moving die plate hole near be provided with the support of supporting rod; On moving die plate, also be provided with hydraulic jack, on the piston rod of hydraulic jack, be fixed with the flexible skewback that matches with above-mentioned skewback; On long leading truck, be fixed with horizontal piece, on horizontal piece, be provided with the adjusting device of regulating supporting moving mold position.On fixed form, also be provided with the bearing support of supporting rod, on pull bar, also be provided with the antirotation keys that prevents that pull bar from rotating, on pull bar, also be provided with the nut of adjusting yoke outreach length.Above-mentioned adjusting device is for regulating bolt.
Another kind of scheme is:
On its frame, be fixed with fixed form and guide rail, on fixed form, be provided with fixed mould and folding mould oil cylinder; The piston rod of folding mould oil cylinder is connected with moving die plate; The push rod that moving die plate is provided with moving mold and mould is ejected also is fixed with long leading truck under moving die plate, long leading truck places on the guide rail, it is characterized in that: also be provided with pull bar on moving die plate, also be fixed with a skewback on pull bar; The position of corresponding pull bar has the hole that pull bar can pass on fixed form, be positioned on the fixed form hole near also be provided with the support of supporting rod; On fixed form, also be provided with hydraulic jack, on the piston rod of hydraulic jack, be fixed with the flexible skewback that matches with above-mentioned skewback; On long leading truck, be fixed with horizontal piece, on horizontal piece, be provided with the adjusting device of regulating supporting moving mold position.On moving die plate, also be provided with the bearing support of supporting rod, on pull bar, also be provided with the antirotation keys that prevents that pull bar from rotating, on pull bar, also be provided with the nut of adjusting yoke outreach length.Above-mentioned adjusting device is for regulating bolt.
The present invention compared with prior art has following advantage:
1. the stressed length of pull bar has reduced more than 30%, thereby has reduced the elastic deformation amount who is produced by clamp force, has improved the formed precision of goods.
2. owing to adopted flexible skewback and the amplification that the extruding of fixing skewback has produced power, reduced and used oil mass, memorandum energy consumption, available small oil tank locked mode replacement large tank locked mode, seal is easily purchased easily and is changed, and simultaneously, has reduced the chance of leakage of oil.
3. action is few, and valve member is few, is easy to use maintenance, and molding cycle is short, has improved production efficiency.
4. the synchronous precision prescribed of this clamping apparatus mode transfer is not high, laborsaving, can omit whole mode transfer system, as long as just can reach requirement with four mode transfer nuts of manual adjustments.
5. adopt mould supporting governor motion, pipe mold does not have the multiple moving die plate that can both guarantee to move freely, does not have unbalance loading, the kinematic accuracy height.
