Description

Technical Field

[0001] This utility model relates to the field of injection molding machine part removal technology, specifically to an automatic part removal device for injection molding machines using a robotic arm. Background Technology

[0002] Plastic injection molding process includes injection molding and part removal. The part removal process usually utilizes the mold ejection mechanism to eject the plastic part when the mold opens, separating the plastic part from the mold cavity. At the same time, the part removal device of the automated production line removes the ejected plastic part. When some plastic parts with deep recesses are ejected and transferred by the mold ejection mechanism, there are two problems: First, the ejection mechanism cannot completely eject such plastic parts, and the plastic parts are prone to getting stuck on the extrusion mold; second, the part removal is limited by the length of the extrusion mold after demolding, which presents a problem.

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0015] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0016] For ease of explanation, spatial relative terms such as “up,” “down,” “left,” and “right” may be used herein to describe the relationship of one element or feature shown in the figure relative to another element or feature. It should be understood that, in addition to the orientation shown in the figure, spatial terms are intended to include different orientations of the device in use or operation. For example, if the device in the figure is inverted, an element described as being “down” of other elements or features would be positioned “up” of those other elements or features. Therefore, the exemplary term “down” can encompass both up and down orientations.

[0019] The working principle of this utility model is as follows: First, adjust the distance between the two demolding frames 20 according to the width of the plastic part. Then, start the reduction motor 1 to move the slide table and mounting plate 21 above the plastic part. Start the cylinder 11 to open the distance between the demolding frame 20 and the suction cup 12. Start the servo motor 5 to make the demolding frame 20 snap into the back of the plastic part. Start the cylinder 11 to retract. The demolding frame 20 pulls the plastic part backward and is sucked by the suction cup 12. During the process of the demolding frame 20 pulling backward, the suction cup 12 can move backward with the slide rod 17. The plastic part is completely removed from the injection molding machine mold, and the part is removed. The plastic part is then transferred to the side (a conveyor belt can be placed to transfer the plastic part).
