Description

The parallel-moving type clamping of crooking one's arm
Technical field
The utility model relates to a kind of parallel-moving type clamping of crooking one's arm, and is applied on the make-up machine parts of plastics extrusion blow molding blow moulding machine, finishes the final molding of plastic products.
Background technology
The mold closing mechanism of blow moulding machine, main variation in recent years are further to energy-conservationization development.Early stage mold closing mechanism mostly adopts four plate hydraulic pressure Direct Action Types, and energy consumption is bigger, and complex structure developed into present use four-pull-rod three plate coordinated types more widely afterwards.In in the past 10 years, the mold closing mechanism of the blowing blow moulding machine that each company puts on market, its outside change of shape is bigger, also have to adopt three pull bars, but essence can be included into three plate linkage structures.The major defect of three early stage plate coordinated type mold closing mechanisms is to have 3~4 pull bars, make the space of clamping mould be subjected to certain restriction, and it is huger to install this body structure.The clamping of large-scale hollow machine progressively trends towards adopting two plate locks in recent years; the mold clamping force of this two-plate mold closing mechanism is to be realized by two or three pairs of (4 or 6) position locked mode cylinder adjustable, that be positioned at the template both sides, but to the rigging position and the required precision height of locked mode cylinder, cause manufacturing cost to rise.
Summary of the invention
Technical problem to be solved in the utility model: design a kind of parallel-moving type clamping of crooking one's arm, utilize the effect and the control of opening and closing mould oil cylinder, reasonable distribution by the moment of crooking one's arm, promote template and on the translation guide rail, move horizontally, finish the plastic product forming technical process of die sinking, matched moulds, locked mode; And make maximum clamp force reasonable distribution.
Technical solution of the present utility model: a kind of parallel-moving type clamping of crooking one's arm, its frame (1) is provided with workbench (5), be shaped on translation guide rail (4) on the workbench (5), symmetrically arranged template (7) (8) is positioned on workbench (5) and the translation guide rail (4) and can moves horizontally; The outer pivoted arm (2) that then all is hinged with of template (7) (8), in then all be fixed with mould, the middle part of symmetrically arranged two crook one's arm (3) all is hinged on the two ends of workbench (5), and the upper end of two crook one's arm (3) is hinged with the other end of pivoted arm (2) respectively, and the lower end is hinged with the two ends of opening and closing mould oil cylinder (6) respectively.
Two translation guide rails (4) are housed on the workbench (5).Be connected with lazy-tongs (9) between the template (7) (8).Can be symmetrical arranged the above-mentioned clamping of two covers on the frame (1).
Advantage that the utility model compared with prior art has and effect:
1, three templates, the three pull bar clampings of using on the utility model and the common plastic molding press are compared, and have simple in structurely, compact, are convenient to adjust, the clamping mould is convenient, adapts to characteristics such as plurality of specifications production of articles, saves manufacturing cost simultaneously.
2, the utility model applies to technology of Machine Tool the manufacturing technology of System of Hollow Blow Shaping Machine.The shifting formwork motion promotes template and mould by the oil cylinder of bottom, and horizontal movement realizes on line slideway, so the motion of template has good rigidly, kinematic accuracy height, repeatable accuracy height, the brisk advantage of motion; And, make the more reasonable stress of mechanism itself by reasonable distribution to the arm of force and moment.
3, the utility model features simple structure, it is little to take up room, and is best suited for the production of double, saves a large amount of moulding cool time in the production process of product molding, and the production efficiency of hollow machine is doubled, and has solved the low problem of production efficiency.
4, the utility model in process of production the user can produce the goods of different size, difformity, Different Weight simultaneously according to the demand in market, solved the problem that hollow machine in the past simultaneously can only be produced a kind of specification goods, have high economic benefit.

Fig. 2 is the structure vertical view of a kind of embodiment of the utility model,
Fig. 3 is the structural perspective of a kind of embodiment of the utility model.
The specific embodiment
1,2,3 a kind of embodiment of the present utility model is described in conjunction with the accompanying drawings.
A kind of parallel-moving type clamping of crooking one's arm is symmetrically arranged with two workbenches (5) on its frame (1).All be shaped on two translation guide rails (4) on each workbench (5), symmetrically arranged template (7) (8) is positioned on workbench (5) and the translation guide rail (4) and can moves horizontally; The outer pivoted arm (2) that then all is hinged with of template (7) (8), in then all be fixed with mould, the middle part of symmetrically arranged two crook one's arm (3) all is hinged on the two ends of workbench (5), and the upper end of two crook one's arm (3) is hinged with the other end of pivoted arm (2) respectively, and the lower end is hinged with the two ends of opening and closing mould oil cylinder (6) respectively.In order to guarantee the template accurate action of opening and closing mould simultaneously in the horizontal direction, therefore between template (7) (8), be connected with lazy-tongs (9).
Operation principle: utilization is split, the effect and the control of die cylinder (6), by the motion of crook one's arm (3), pivoted arm (2), guarantees that at first template (7) (8) upward moves horizontally at workbench (5) and translation guide rail (4); Auxiliary with lazy-tongs (9), finish the template accurate action of opening and closing mould simultaneously in the horizontal direction.Secondly, by (3) the upward reasonable distribution of moment of crooking one's arm,, make this mechanism maximum clamp force when plastic product forming reach 150KN (15 tons), maximum goods volume 30L (30 liters) to the reasonable decomposition that pivoted arm (2) is gone up active force.During locked mode, utilize the weight of the system point decomposition mould of pivoted arm (2), the suffered vertical stress component of translation guide rail (4) on the workbench (5) is greatly reduced.And by adjusting the displacement of opening and closing mould oil cylinders (6); mould on the adjustment template (7) (8) is at the mounting distance of level, vertical both direction; make this clamping finish the forming process of different size plastic products in the prescribed limit, produce the plastic products of different size.
