Description
Technical field
The utility model relates to the clamping of plastic extrusion blowing machine, belongs to the plastics machinery field.
Background technology
The plastic extrusion blowing make-up machine is widely used in producing various bottle for cosmetics, medicine bottle and beverage bottle etc.At present; the clamping of large-scale extrusion blow hollow plastic make-up machine is continued to use the structure of small hollow container forming machine clamping; adopt three plate interlock and expansion structures thereof of two pull bars or four-pull-rod; major defect is: the template discontinuity; the phenomenon of mould easily rises; because the existence of pull bar makes the space of mould be subjected to certain limitation, the operating space of manipulator is suffered restraints simultaneously.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming that prior art exists, to provide a kind of clamp force strong, and is not easy to wear, and motion is steady, the clamping of the plastic extrusion blowing machine that running precision is high.
The technical scheme of the clamping of the utility model plastic extrusion blowing machine is: a support is arranged, plastic extruder structure, material cutting mechanism, blow mold and clasp mould mechanism are installed on the support, described plastic extruder structure is that motor is through the helix extrusion device behind the deceleration device, pressurizing unit connects the blank extrusion die, and the blow needle of bottle mechanism is arranged on the die head; Described material cutting mechanism is that cylinder is moved in the material cutting that is connected on the frame, and material cutting is moved cylinder and driven support, and the material cutting heating wire is installed on the support; It is characterized in that described blow mold and clasp mould mechanism are two translation oscillating arm mechanisms; at the front template and the rear pattern plate back side swing arm connecting rod is housed respectively; in swing arm connecting rod bottom surface slide block is housed; the swing arm connecting rod connects swing arm; left and right sides swing arm is driven by draft cylinder; swing arm middle part, the left and right sides is fixed by two base plates; plate top surface is shaped on line slideway; guide rail matches with slide block; on a side base plate, be fixed with lazy-tongs; lazy-tongs are by left synchronising (connecting) rod; swing arm synchronously and right synchronising (connecting) rod are formed; swing arm synchronously is fixed on the base plate, and left synchronising (connecting) rod one end is fixed on the front template, and the other end is fixed on synchronous swing arm left end; right synchronising (connecting) rod one end is fixed on the rear pattern plate, and the other end is fixed on synchronous swing arm right-hand member.
The clamping of the utility model plastic extrusion blowing machine; when die sinking; piston in the draft cylinder is withdrawn inward; driving right swing arm turns clockwise around fulcrum; left side swing arm is rotated counterclockwise around fulcrum; swing arm drives the swing arm connecting rod; the swing arm connecting rod drives template again and skids off outward, and the also and then rotation of lazy-tongs this moment is when piston moves to range; cylinder quits work; because template and unstable before and after the effect of inertia continues the direction motion to die sinking, thereby promotes piston; damage cylinder, and die sinking is also unstable.But synchronous self-locking mechanism has been arranged, when piston moves to range, the left synchronising (connecting) rod of lazy-tongs, swing arm synchronously and the motion of right synchronising (connecting) rod form spacing, the inertia force that the front and back template is moved laterally and the pulling force of lazy-tongs offset, thereby reduce wearing and tearing, and locked mode puts accurately in place to cylinder.Otherwise when matched moulds, piston in the draft cylinder is protruding, driving right swing arm is rotated counterclockwise around fulcrum, left side swing arm turns clockwise around fulcrum, swing arm drives the swing arm connecting rod, the swing arm connecting rod drives template again and slides into inward, lazy-tongs are and then rotation also, when piston reaches range, the left synchronising (connecting) rod of lazy-tongs and right synchronising (connecting) rod are run into the boss in the synchronous swing arm, the inertia force that template is moved inwards before and after making and the pressure of lazy-tongs offset, the same wearing and tearing that reduce cylinder.
Description of drawings
Fig. 1 is the structural representation of plastic extrusion blowing machine under the matched moulds state;
Fig. 2 is the structural representation of plastic extrusion blowing machine under the die opening state.
The specific embodiment
The utility model relates to a kind of clamping of plastic extrusion blowing machine, as shown in Figure 1 and Figure 2, a support 1 is arranged, plastic extruder structure, material cutting mechanism, blow mold and clasp mould mechanism are installed on the support 1, described plastic extruder structure is that motor is through the helix extrusion device 4 behind the deceleration device 3, deceleration and pressurizing unit are installed on the platform 2, and pressurizing unit connects blank extrusion die 6, and the blow needle 5 of bottle mechanism is arranged on the die head; Described material cutting mechanism is that cylinder 18 is moved in the material cutting that is connected on the frame, and material cutting is moved cylinder and driven support and heating wire 7; It is characterized in that described blow mold and clasp mould mechanism are two translation oscillating arm mechanisms; the concrete structure of two translation oscillating arm mechanisms is at the front template 9 and rear pattern plate 8 back sides swing arm connecting rod 10 to be housed respectively; in swing arm connecting rod 10 bottom surfaces slide block 16 is housed; the swing arm connecting rod connects swing arm 11; left and right sides swing arm is driven by draft cylinder 15; swing arm middle part, the left and right sides is fixed by two base plates 12; plate top surface is shaped on line slideway; line slideway matches with slide block 16; on a side base plate, be fixed with lazy-tongs; lazy-tongs are by left synchronising (connecting) rod 13; swing arm 14 synchronously and right synchronising (connecting) rod 17 are formed; swing arm 14 synchronously is fixed on the base plate 12, and left synchronising (connecting) rod 13 1 ends are fixed on the front template 9, and the other end is fixed on synchronous swing arm 14 left ends; right synchronising (connecting) rod 17 1 ends are fixed on the rear pattern plate 8, and the other end is fixed on synchronous swing arm 14 right-hand members.When die sinking, piston in the draft cylinder is withdrawn inward, driving right swing arm turns clockwise around fulcrum, left side swing arm is rotated counterclockwise around fulcrum, swing arm drives the swing arm connecting rod, the swing arm connecting rod drives template again and skids off outward, the also and then rotation of lazy-tongs this moment, when piston moves to range (all withdrawals), cylinder quits work, at this moment the left synchronising (connecting) rod of lazy-tongs, swing arm synchronously and the motion of right synchronising (connecting) rod form spacing (at this moment left and right sides synchronising (connecting) rod reaches range), and the inertia force that the front and back template is moved laterally and the pulling force of lazy-tongs offset, thereby reduce wearing and tearing, and locked mode puts accurately in place to cylinder.Otherwise when matched moulds, piston in the draft cylinder is protruding, driving right swing arm is rotated counterclockwise around fulcrum, left side swing arm turns clockwise around fulcrum, swing arm drives the swing arm connecting rod, the swing arm connecting rod drives template again and slides into inward, lazy-tongs are and then rotation also, when piston reaches range, left side synchronising (connecting) rod and right synchronising (connecting) rod are run into the boss (at this moment left and right sides synchronising (connecting) rod reaches minimum stroke) in the synchronous swing arm, and the inertia force that template is moved inwards before and after making and the pressure of lazy-tongs offset, and not only reduce the collision of male model and master mold, matched moulds is steady, and reduces the wearing and tearing to cylinder.Its described line slideway can be the ball line slideway, and not only coefficient of friction is little, and motion is steady, and the running precision height.
