Description

Mechanical arm for plastic flower core pulling

Technical Field

The utility model relates to a plastics flower moulding-die technical field specifically is a manipulator that is used for plastics flower to loose core.

Background

The distance tensioning mechanism such as a plastic draw hook is generally used in a mold with a cavity for core pulling or secondary demolding, and because the mechanism is designed on two side surfaces of the mold, the action requirements of the mechanism are synchronous, namely, the mold is closed and the hasp is buckled at the same time, and the mold is opened to a certain position and the draw hook is pulled at the same time. Once the synchronization is lost, the template of the injection mold is scratched or skewed and damaged, parts of the design structures need to have higher rigidity and wear resistance, the adjustment is difficult, the service life of the mechanism is short, the use is avoided as far as possible, other design structures can be used instead, a spring-assisted ejection method can be adopted under the condition that the core pulling action is small, the core sliding during the moving of the movable mold is needed when the core pulling action is large, the structure that the core pulling action is completed firstly and then the mold is separated can be adopted, and the hydraulic oil cylinder can be adopted for core pulling on a large mold. The angle pin slider type core-pulling mechanism is damaged. The most common defects of the mechanism are that the mechanism is not in place in processing and the material consumption is too small, and the following two problems are mainly caused. The angle of inclination A of the angle pin is large, and the advantage is that a large core-pulling distance can be generated in a short mold opening stroke of the injection mold. However, if the inclination angle a is too large, the bending force P = F/COSA applied to the taper pin during the core back process is also large when the drawing force F is a certain value, and the taper pin is likely to deform and the taper hole is likely to wear. Meanwhile, the larger the upward thrust N = FTGA generated by the inclined pin to the sliding block is, the larger the positive pressure of the sliding block to the guide surface in the guide groove is, and therefore the friction resistance when the sliding block slides is increased. The sliding is not smooth and the guide groove is worn easily. According to experience, the inclination angle A is not larger than 2, the length of the guide groove is too small due to the limitation of the area of the template, and the slide block is exposed out of the guide groove after the core pulling action is finished, so that the slide block is easy to incline in the post core pulling stage and the initial die closing reset stage, and particularly when the die is closed, the slide block is unsmooth in reset, so that the slide block is damaged and even bent and damaged. According to experience, after the sliding block completes the core pulling action, the length of the sliding block left in the sliding groove is not less than 2/3 of the whole length of the guide groove.

Plastics flower when the mould is moulded the type, also need adopt the operation of loosing core, because during the operation of loosing core, the mould does not cool off completely, generally adopts artifical wearing heat-proof gloves to operate, also can adopt the manipulator to loose core the operation, current manipulator when the operation, the orbit of loosing core is uncontrollable, easily causes moulding product to appear the quality problems, and it is exactly that in addition, the mechanical wear rate of manipulator is higher, under the condition of long-time wearing and tearing, still can influence the orbit of loosing core in later stage.
