Description
Technical field
The present invention relates to a kind of injection machine, but particularly a kind of quickly opening and closing mould is suitable for the comprehensive die sinking injection machine of production high precision, baroque injecting products.
Background technology
Traditional injection machine has two mould (see figure 1)s, 101, one dynamic models 102 of one of them cover half, dynamic model in the driving lower edge of oil cylinder guide pillar 103 reciprocating, accomplish to close the function of mould and die sinking.A die sinking direction is only arranged.Because the production efficiency of injection machine is high, is convenient to realize automation, in the production of plastic part, is used widely.But it still has many shortcomings, and for example: the proportion of finished product and waste material is higher, and speed of production slow (with respect to comprehensive die sinking injection machine) is easy to generate burr, and die manufacturing cost is high, and energy resource consumption is big or the like.The more important thing is: difficulty is very big in the production of small-sized, precision and complicated parts, and production cost and die cost are high.
The utility model content
The objective of the invention is to overcome the deficiency of above-mentioned technology, provide a kind of production efficiency high, simple to operate, safe, efficient, produce and stablize, the injecting products quality is high, the comprehensive die sinking injection machine that production cost is low.
The technical solution adopted for the present invention to solve the technical problems is: this comprehensive die sinking numerical control injection machine has the mainboard of an inclination; A front cross chute die holder that is installed in mainboard, at least two groups are directed doing reciprocating linear motion in chute through the sliding mould that crank connecting rod mechanism connects.
Four base supports are fixed on the mainboard front, are used for operationally fixing each crank connecting rod mechanism assembly, cylinder, oil hydraulic cylinder, position detecting device etc.Oil hydraulic cylinder is fixed on retaining mechanism central hole location on the base support.Each crank connecting rod mechanism locks together through retaining mechanism and the oil hydraulic cylinder that is fixed on the base support; And be connected by the pin pivot with each slide block mould with cylinder axis respectively; The slide block mould is placed in the chute of cross mould bases; And in chute, make reciprocal linear slide by the interlock of cylinder and crank connecting rod mechanism, accomplish the function of closing mould and die sinking.Simultaneously mould is applied extra clamp force by the oil hydraulic cylinder that links to each other with the crank connecting rod mechanism other end.Base support is interconnected to form an integral body through screw or welding, so that prevent the deflection for the caused bearing of pressure that keeps clamp force and produce owing to crank connecting rod mechanism.
An injecting systems is used for when sliding mould is in the Guan Mo position, melted material is injected in the die cavity of sliding mould; A drive unit that connects injection seat and be fixed on the said mainboard back side is used to realize advancing or retreating of injection seat, and guarantees that injection-moulding nozzle closely contacts with mould that generation can be sealed the injection seat pressure of melt.
One group of cylinder that is used to make sliding mould to do die sinking and Guan Mo action, cylinder is connected on the said base support through L shaped connecting plate, and the end pivot of the horizontal member in cylinder axis and the crank connecting rod mechanism is connected.The reciprocating motion of cylinder axis just is transformed into the die sinking and the Guan Mo action of sliding mould through this crank connecting rod.Each oil hydraulic cylinder is fixed on retaining mechanism central hole location on the base support, is connected with each crank connecting rod mechanism through retaining mechanism, is used for mould is applied extra clamp force.Each connector comprises that a plurality of pivots connect, thus the mobile dislocation that produces when allowing above-mentioned drive unit, crank connecting rod transferring power.The control system comprises: be used to detect the die sinking of sliding mould and the device of Guan Mo position, it is realized through the position of the middle-end connecting pin of detection crank connecting rod.
Drive unit, crank connecting rod mechanism assembly and position detecting device etc. can be installed, change and regulated to the frame for movement of this comprehensive die sinking injection machine easily.
During use, each slide block mould of comprehensive die sinking injection machine is under the interlock of drive unit and crank connecting rod mechanism, by the pass mould stop mould of setting; Injecting systems enters into injecting step then; Screw rod with high speed, high pressure, is expelled to the melted material in the storage compartment in the die cavity of mould under the effect of injection drive unit through nozzle; And after pressurize, cooling, solidifying and setting; By the order opening mold of setting, through the demoulding and inflatable body goods are sent into charging basket, begin next circulation simultaneously.Technology is simple, stable, efficient.
All temps sensor in the control system, position sensor detect the temperature signal of each position component signal and injecting systems in real time; These signals are sent in the control system, and the control system realizes the coordination of each parts of system and mechanism by the program of establishment in advance.
The invention has the beneficial effects as follows: this comprehensive die sinking injection machine improves the production efficiency of injecting products greatly, makes operation more simply, safely, efficiently, has improved the quality of production stability and die-cast product, reduces the manufacturing cost of die-cast product.Be suitable for production high precision, complex structure, do not have burr or the minimized plastic product of burr.
