Description
Technical field
The present invention relates to a kind of folding mould and locked mode method, particularly relate to folding mould and the locked mode method of the equipment such as a kind of die casting machine, extrusion casting machine and injection machine.
Background technology
Die casting machine and extrusion casting machine etc. are mainly for the production of the foundry goods of the metals such as aluminium, magnesium, zinc and copper and alloy thereof, and injection machine is mainly for the production of plastic fittings.Die casting machine, extrusion casting machine and injection machine are made up of mould adjusting mechanism, clamping, injection mechanism, hydraulic pressure and electrical apparatus control system and safety protective mechanisms etc. usually, and wherein clamping is one of core component of this kind equipment.
The clamping of die casting machine, extrusion casting machine and injection machine perform the folding of die-filling tool and locking action; usually be made up of three pieces of templates and four Gen Gelin posts; three pieces of templates are divided into again solid plate, moving platen and tailgate usually; mould is fixed on solid plate and moving platen usually; moving platen can be reciprocating along the guiding of four Gen Gelin posts, realizes opening mould assembling action.Die casting, extrusion casint or injection moulding time, mould must be locked in case metal or plastics eject in mould, affects formed product and quality, and therefore, the size of clamp force is one of key performance of this kind equipment.
At present, folding mould and the locked mode method of known kind kind equipment mainly contain three kinds: 1. crank connecting rod expands force method, 2. direct hydraulic method, and 3. method held tightly by brother woods post.Wherein first method, namely crank connecting rod expands force method is method the most frequently used at present, its principle uses less hydraulic thrust to expand power to reach required clamp force by crank connecting rod, the advantage of this method is that hydraulic system is relatively simple, the power consumption of equipment is also relatively less, shortcoming is that crank connecting rod mechanism is more complicated, its requirement on machining accuracy is high, the cost of manufacture of equipment is also relatively high, in addition, use the equipment of this mechanism, the clamp force causing the elongation of taxi driver brother woods post easily to cause it to set due to system motion heating and variation of ambient temperature weakens even to be lost, second method, i.e. direct hydraulic method, utilize the moving platen of one or more this kind equipment of hydraulic cylinder Direct driver to perform folding mould and locked mode action, the advantage of this method is that the structure of equipment is relatively simple, shortcoming is that operational outfit needs a large amount of hydraulic oil, the power consumption of equipment is very large, the overall dimensions of Mode-locking oil cylinder is very large in addition, cost of manufacture is high, if the patent No. is that the Quick cylinder that 201110114085.2 disclosed a kind of " a kind of high-efficiency and energy-saving type clapper die spotting press and closing methods " adopt two cylinder diameters less drives, advantage is that structure is simple, shortcoming is that closing cylinder size is larger, increase cost of manufacture, and do not reduce by oil mass during the large locked mode of impulse stroke thus cause energy waste comparatively serious, for another example the patent No. is 201110213922.7 disclosed a kind of " high energy saving die casting machine servo control mechanisms ", control by increasing servo control mechanism, advantage is that efficiency is high, compact conformation, shortcoming is that increase servo control mechanism cost is higher, and relatively and the patent No. be 201110114085.2 locked mode process, its stroke is larger, more thus cause energy waste even more serious by oil mass, above-mentioned two patents all do not solve the shortcomings such as stroke is large, energy consumption is high, and therefore there be limited evidence currently of die casting machine, extrusion casting machine or injection machine adopt this method, the third taxi driver brother woods post method of holding tightly is a kind of relatively new method, method disclosed in International Patent Publication No. WO2006/082608, its principle uses one or more less Driven by Hydraulic Cylinder moving platens to perform to open mould assembling action, use the hollow hydraulic cylinder being fixed on four little stroke large-diameter on moving platen and four brother woods post hold-fast bodies to perform locked mode action in addition, the advantage of this method is that the power consumption of equipment is few, the compact conformation of equipment, shortcoming is clamping system complex structure, the machining accuracy of mechanism requires very high, the cost of manufacture of equipment is relatively high, in addition, because locked mode action can produce certain wearing and tearing to brother woods post, equipment may need to change whole taxi driver brother woods post after running certain hour, cause the maintenance cost of equipment very high.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of folding mould and the locked mode method of new die casting machine, extrusion casting machine and injection machine is provided, make the structure of this kind equipment simple, consume energy low and production cost is low.
The technical solution adopted for the present invention to solve the technical problems is: a kind of folding mould and clamping mechanism, comprise frame, be arranged on the first template in frame, be arranged on the second template of the first template side, guiding brother woods post, at least one first hydraulic actuator, at least one second hydraulic actuator and the moving platen be placed between the first described template and the second template, the two ends of described guiding brother woods post are connected with the second template with the first described template respectively, mould is provided with between described moving platen and the first template, described moving platen by through the guiding brother woods post described in wherein guiding and move back and forth along guiding brother woods post with the die sinking realizing this folding mould and clamping mechanism, the procedure calls of matched moulds and locked mode, it is characterized in that: described folding mould and clamping mechanism also comprise the baffle element that at least one supporter being arranged on moving platen side and at least one and supporter cooperatively interact.
A kind of folding mould and locked mode method, is characterized in that, comprise following action:
A, die sinking, matched moulds: moving platen is carried out along guiding brother woods post the action that back and forth movement realizes die sinking and matched moulds by the first hydraulic actuator;
B, locked mode: the clamp force produced by the second hydraulic actuator action moving platen being moved along guiding brother woods post to the first template realize locked mode by the barrier effect of supporter and baffle element or the clamp force that coordinates the second hydraulic actuator jointly to produce by the first hydraulic actuator also make moving platen move along guiding brother woods post to the first template by the barrier effect of supporter and baffle element to realize the action of locked mode.
Beneficial effect of the present invention:
1, the baffle element that the present invention is arranged can according to the needs of folding mould and locked mode, and be placed in the side of supporter or remove, the supporter being arranged on moving platen side makes the stroke of the second hydraulic actuator greatly shorten, and oil-filled amount reduces, and makes the energy consumption when locked mode low; 2, when the power that folding mould and locked mode separate is arranged so that apparatus of the present invention work, heating is few, the impact that can not be expanded with heat and contract with cold and produce large deviation, ensures that locked mode is reliable and stable; 3, baffle element and supporting body structure simplicity of design, when supporter and baffle element damage, easily changes, simple to operate, safe and reliable, and long service life of the present invention, lower to processing request, manufacture and the maintenance cost of mechanism of the present invention production and processing can be reduced.
