A Grabbing Manipulator for Plastic Injection Parts

Abstract

A gripping manipulator for glue injection parts, comprising a bracket, and N groups of grabbing mechanisms and blowing mechanisms installed on the bracket, on which the main rod 1 is connected by bolts; the grabbing mechanism includes the same structure, connected Two pairs of fixtures, left and right fixture push rods and fixture cylinders are integrated into one body, and return springs are installed on the left and right fixtures, and the two pairs of fixtures are clamped or loosened under the drive of the fixture cylinder; the blowing The mechanism includes two air cylinders, left and right air cylinder push rods and air cylinder cylinders. fall or rise. The grabbing manipulator combines motorized demoulding and air pressure demoulding, with safe operation, firm and stable clamping parts, high efficiency, greatly reduced labor intensity, and environmental protection.

Description

technical field [0001] The invention relates to an auxiliary device of glue injection equipment, in particular to a grasping manipulator used for taking out glue injection parts of automobile shock absorber dustproof bellows. Background technique [0002] In the traditional manufacturing of automobile shock absorber dust-proof bellows, the workpiece must be released from the mold cavity. At present, the methods for removing the automobile shock absorber dust-proof bellows produced in the mold are: [0003] 1. The hydraulic adsorption manipulator is adopted. Its working principle is to extend the elastic finger into the workpiece with a hole-like structure, and then inject hydraulic oil from the connecting core seat into the elastic finger, and the elastic finger expands to grab the hole-like workpiece. For the workpiece of the structure, after the oil is drained, the elastic finger returns to the normal state, and the stripping spring assists in lowering the workpiece. Howe...

Problems solved by technology

However, the scope of application of this design is relatively small, and it can only be used for parts with round holes, and the quality of the parts should not be too large. slide

[0004]2. Suction cup adsorption type manipulator is adopted. The key part of this manipulator is the suction cup, and the object is taken out through the suction cup. The working surface of the parts to be taken has certain requirements, and the structure is complex and expensive, so it is not suitable for simple injection molding machines

[0005] 3. Manual retrieving. After the parts are formed, the workpieces are taken out of the mold one by one by the manual ejection mechanism. Not only is the efficiency low and the scrap rate is high, but it is also easy to be scalded by the high-temperature mold, and a large amount of harmful substances are produced during retrieving. gas, harmful to workers' health
