Abstract
The invention discloses a mold opening and closing device capable of self locking in a closing state in a blow molding machine, which comprises a mold opening and closing driving motor, a pair of molding boards, a pair of swing arms and a crank formed by a driving swing rod and a pair of driven swing rods, wherein the molding boards and the swing arms are arranged on a movable mold seat. The upper end of each swing arm is movably articulated with the molding board at the same side by a connecting rod; the output shaft of the mold opening and closing driving motor is fixed on the middle part of the driving swing rod; two ends of the driving swing rod are movably articulated with one end of the driven swing rod; and the other end of each driven swing rod is movably articulated with the lower end of the swing arm at the same side. The invention is used in various blow molding machines.
Description
Technical field
The present invention relates to blow moulding machine, refer more particularly to the folding mould device in the blow moulding machine.
Background technology
Folding mould device in the present blow moulding machine, owing to there is not self-locking mechanism, at the matched moulds state, the drive unit of clasp mould mechanism is in running order always, to keep enough clamp forces, has so just caused the waste of the energy, has increased production cost.
Summary of the invention
Technical problem to be solved by this invention is: a kind of folding mould device in the matched moulds state can the blow moulding machine of self-locking is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is: the folding mould device in the blow moulding machine, comprise: folding mould drive motors, the crank that is arranged on a pair of template on the shifting formwork seat and a pair of swing arm and constitutes by active fork and a pair of passive fork, the upper end of each swing arm is movably hinged by the template of connecting rod and homonymy; The output shaft of folding mould drive motors is fixed on the initiatively middle part of fork, and initiatively the two ends of fork are movably hinged with an end of a velamen movable pendulum bar respectively, and the other end of two velamen movable pendulum bars is movably hinged with the lower end of homonymy swing arm respectively.
The invention has the beneficial effects as follows: link to each other by crank between a pair of swing arm among the present invention, at the matched moulds state, active fork in the crank and a pair of passive fork are a straight line and arrange, initiatively the passive fork of fork and both sides forms the dead point, thereby realized automatic locked mode, thereby greatly reduce the energy resource consumption of folding mould drive motors, reduced production cost.
Description of drawings
Fig. 1 is a structural representation of the present invention.
Fig. 2 is the structural representation that the crank among Fig. 1 is in self-locking state.
Among Fig. 1 to Fig. 2: 1, template, 2, connecting rod, 3, swing arm, 4, the shifting formwork seat, 5, the shifting formwork frame, 6, fork initiatively, 7, left passive fork, 8, right passive fork, 9, slide block, 10, guide rail, 11, driving shaft.
The specific embodiment
Below in conjunction with accompanying drawing, describe specific embodiments of the present invention in detail.
As shown in Figure 1, folding mould device in the blow moulding machine of the present invention, comprise: folding mould drive motors, be arranged on a pair of template 1 on the shifting formwork seat 4 and a pair of swing arm 3 and by active fork 6 and left and right passive fork 7 and 8 cranks that constitute, shifting formwork seat 4 is fixed on the shifting formwork frame 5, and shifting formwork frame 5 is arranged on a pair of guide rail 10 that is fixed on the frame by a pair of slide block 9 of its bottom; The upper end of each swing arm 3 is movably hinged by the template 1 of connecting rod 2 with homonymy; The driving shaft 11 that the output shaft of folding mould drive motors promptly is used to drive crank is fixed on the initiatively middle part of fork 6, initiatively the two ends of fork 6 are movably hinged with an end of left and right passive fork 7 and 8 respectively, and the left and right passive fork 7 and 8 the other end are movably hinged with the lower end of homonymy swing arm 3 respectively.
The course of work of the present invention is: during matched moulds, folding mould drive motors drives initiatively by its output shaft, and fork 6 rotates counterclockwise, left and right passive fork 7 and 8 is stretched directly, is made a pair of template 1 under the effect of swing arm 3, draw close to the center---referring to Fig. 2, the pipe in the blowing head is clamped; At this moment, active fork 6 in the crank and left and right passive fork 7 and 8 are a straight line arranges, and initiatively fork 6 forms the dead point with left and right passive fork 7 and 8, realizes automatic locked mode; During die sinking, folding mould drive motors drives initiatively by its output shaft that fork 6 clockwise rotates, and left and right passive fork 7 and 8 is inwardly drawn in, makes a pair of template 1 open to both sides.
Claims (1)
1. the folding mould device in the blow moulding machine comprises: folding mould drive motors and be arranged on a pair of template and a pair of swing arm on the shifting formwork seat, and the upper end of each swing arm is movably hinged by the template of connecting rod and homonymy; It is characterized in that: described folding mould device also includes the crank that is made of active fork and a pair of passive fork, the output shaft of folding mould drive motors is fixed on the initiatively middle part of fork, initiatively the two ends of fork are movably hinged with an end of a velamen movable pendulum bar respectively, and the other end of two velamen movable pendulum bars is movably hinged with the lower end of homonymy swing arm respectively.
