Description
Technical field
The present invention relates to the die casting machine for die-cast metal, relate in particular to folding mould and the locked mode method of die casting machine.
Background technology
Die casting machine is mainly for the production of the foundry goods of the metals such as aluminium, magnesium, zinc and copper and alloy thereof.Die casting machine mainly is comprised of mould adjusting mechanism, clamping, injection mechanism, hydraulic control system, electric control system and safety protective mechanisms etc. usually.Wherein clamping is one of core component of die casting machine.
The clamping of die casting machine is carried out folding and the locking action of die casting, usually is comprised of three templates and four Gen Gelin posts; Brother woods post die casting machine perpendicular to the ground is referred to as vertical die-casting machine, and the parallel to the ground or die casting machine that be certain acute angle of brother woods post is referred to as horizontal plunger die casting machine.Three templates of the clamping of die casting machine are divided into not only the first solid plate (claim not only a plate), the second solid plate (claim not only tailgate) and moving platen (but also in title plate) usually, and die casting is fixed on the first solid plate and moving platen usually; Moving platen can be reciprocating along four Gen Gelin posts, realizes the action of folding mould.During die casting, die casting must be locked, in case metal ejects in mould, affects shaping and the quality of foundry goods; Therefore, the size of coupling mechanism force is one of key performance of die casting machine.
Known die casting machine folding mould and locked mode method mainly contain three kinds: 1, crank connecting rod expands force method, and 2, direct hydraulic method, 3, brother woods post holds method tightly.Wherein crank connecting rod expansion force method is present the most frequently used method, and its principle is to use less hydraulic thrust to expand power to reach required clamp force by crank connecting rod; The advantage of this method is less energy intensive; shortcoming is to need complicated mould adjusting mechanisms, the distance between namely must adjusting two according to the different-thickness of die casting, and toggle mechanism occupies larger space in addition; need relatively long taxi driver brother woods post, cause the integral rigidity of die casting machine not strong.The folding mould of die casting machine and the second method of locked mode, it is direct hydraulic method, to utilize one or more hydraulic cylinder directly to drive moving platen to carry out the action of folding mould and locked mode, the advantage of this method is that die casting machine is simple in structure, namely do not need mould adjusting mechanism and mode transfer to move/do, in addition, die casting machine taxi driver brother woods post is relatively short, and its integral rigidity is stronger; Its shortcoming is that the power consumption of machine is very large, and therefore, the there be limited evidence currently of die casting machine adopts this method.The third taxi driver brother woods post method of holding tightly is a kind of relatively new die casting machine folding mould and locked mode method, method as disclosed in International Patent Publication No. WO 2006/082608; Its principle is to use one or more less Driven by Hydraulic Cylinder moving platens to carry out the folding mould action of die casting machine, uses in addition hollow hydraulic cylinder and four brother woods post hold-fast bodies of being fixed on four large cylinder diameters of little stroke on moving platen to carry out the locked mode action; The advantage of this method is less energy intensive, and brother woods post is relatively short, and the integral rigidity of die casting machine is stronger; Shortcoming is the clamping system complex structure of die casting machine; The machining accuracy of mechanism, control accuracy all require very high, and the cost of manufacture of machine is relatively high; In addition, this method also needs the mode transfer action of accurately control.
