Abstract
The utility model discloses a mold locking mechanism of two-plate injection machine comprising two fast mold moving cylinders (5) and four direct press type mold locking cylinders (6), wherein the four mold locking cylinders (6) are fixed on a fixed template (4); the fast mold moving cylinders (5) are respectively fixed at the diagonal side edges of the fixed template (4); and a channel is arranged in the fixed template (4) for communicating the oil circuits of the four mold locking cylinders (6). Since the oil circuits of the four mold locking cylinders are communicated by the channel in a fixed template, the mold locking mechanism can eliminate the elements communicated by external oil pipes, thereby reducing oil leakage of pipes and realizing a more compact, simple and beautiful appearance of an injection machine.
Description
Technical field
The utility model relates to a kind of injection machine, specifically is a kind of clamping mechanism of double-plate injection moulding machine.
Background technology
At present, existing injection machine kind has a lot, and clamping mechanism is very important in the structure of injection machine, if clamp force can strut mould inadequately, makes plastic products defective.Wherein, having a kind of is the injection machine that adopts four cylinder vertical compression mould clampings, and especially in double-plate injection moulding machine (injection machine that promptly has only solid plate and two blocks of big plates of moving platen), the most four cylinder direct press types that adopt of its clamping mechanism carry out locked mode.Because clamp force wants stepless action on mould, the plastic products of producing so can not produce finning, the phenomenon of rupture that also reduces the discontinuity of pull bar and take place, the oil that therefore enters four locked mode cylinders will have intimate identical flow velocity and less pressure differential.Clamping mechanism in existing double-plate injection moulding machine adopts the connection of exterior line usually, promptly is connected separately on four locked mode cylinders with oil pipe, makes the part configuration of complete machine more, more complicated like this, also makes the external structure of complete machine huger.
The utility model content
Technical problem to be solved in the utility model is, provide a kind of make the complete machine spare and accessory parts still less, structure is simpler, the clamping mechanism that can reduce the double-plate injection moulding machine of injection machine machine shape size.
For solving the problems of the technologies described above; the clamping mechanism of the utility model double-plate injection moulding machine; comprise two rapid mould-moving oil cylinders, four vertical compression type mould-locking oil cylinders; described four Mode-locking oil cylinders all are fixed on the solid plate; described rapid mould-moving oil cylinder is separately fixed at the diagonal angle side edge of solid plate, has the passage that can link up four Mode-locking oil cylinder oil circuits in the described solid plate.
After adopting above structure, the utility model compared with prior art, has following advantage: because the oil circuit of four Mode-locking oil cylinders is linked up by the passage of solid plate inside, spare and accessory parts have in the past been omitted with the external oil pipe communication, thereby reduce the generation of pipeline oil leakage fault, also make the complete machine external dimensions of injection machine compact, succinct, attractive in appearance more simultaneously.
Described passage is a stepped hole.Adopt such structure,, can go out the diameter of stepped hole like this, thereby guarantee that the hydraulic oil that enters four Mode-locking oil cylinders has identical flow velocity and less pressure differential according to flow, calculation of pressure because channels designs has been become stepped hole.
The oil-in of described passage is positioned at the lower central position of solid plate.After adopting this structure, the high pressure oil-in is arranged on the solid plate lower end, thereby can be fixed on pressurizing cylinder below the frame of injection machine, guarantee the succinct, attractive in appearance of complete machine more.

The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.
By the clamping mechanism schematic diagram of Fig. 1, Fig. 2, the utility model double-plate injection moulding machine shown in Figure 3 as can be known; the clamping mechanism of the utility model double-plate injection moulding machine; comprise two rapid mould-moving oil cylinders 5, four vertical compression type mould-locking oil cylinders 6; described four Mode-locking oil cylinders 6 all are fixed on four angles of solid plate 4; be the piston rod of Mode-locking oil cylinder 6 promptly with pull bar 2; the one end is fixedly connected on the moving platen 1, and the piston in the other end and the Mode-locking oil cylinder 6 is connected.Described rapid mould-moving oil cylinder 5 is separately fixed at the diagonal angle side edge of solid plate 4, and promptly rapid mould-moving oil cylinder piston bar 3 one ends are fixed on the side of moving platen 1, on the piston in an end and the rapid mould-moving oil cylinder 5.Has the passage 7 that to link up four Mode-locking oil cylinder 6 oil circuits in the described solid plate 4.Described passage 7 is a stepped hole.The oil-in 8 of described passage 7 is positioned at the lower central position of solid plate, links to each other with pressurizing cylinder under the frame.
When injection machine during at matched moulds, the rod chamber of rapid mould-moving oil cylinder 5 advances pressure oil, and pulling moving platen 1 moves to solid plate 4.At this moment, the rod chamber of four Mode-locking oil cylinders 6 is communicated with rodless cavity and fuel tank (not shown) through the prefill valve (not shown), and the low pressure oil of rodless cavity flows to rod chamber, and unnecessary oil enters fuel tank.After mould closed tightly, the hydraulic oil of pressurizing cylinder (be positioned at the frame below, show among the figure) passed through in high pressure oil-in 8 admission passages 7 of solid plate 4, and entered the rod chamber formation high pressure of four high-voltage lock mould oil cylinders 6, locked mould like this.
When injection machine during in die sinking, the rod chamber removal pressure of high-voltage lock mould oil cylinder 6 at first, the rodless cavity of rapid mould-moving oil cylinder 5 advances pressure oil promotion moving platen 1 and leaves solid plate 4, the hydraulic oil of the rod chamber of high-voltage lock mould oil cylinder 6 enters rodless cavity through prefill valve at this moment, and not enough oil mass is just replenished by the oil in the fuel tank.
The clamping mechanism of the utility model double-plate injection moulding machine is just the external oil pipe of four Mode-locking oil cylinders of original connection; the passage that transfers in solid plate inside is communicated with; therefore the hydraulic principle of the clamping mechanism of its hydraulic principle and prior art is in full accord, has omitted the hydraulic schematic diagram of clamping mechanism and illustrates accordingly at this.
