Mechanical arm applied to injection molding machine

Abstract

The invention discloses a mechanical arm applied to an injection molding machine. The mechanical arm comprises a base. A first fixed plate is arranged at the upper part of the base. The base is perpendicular to the first fixed plate. A first through hole is formed in one side of the first fixed plate. A rotating shaft is mounted in the first through hole. A motor is connected with one end of the rotating shaft, and is fixed on one side of the first fixed plate. A rotating frame is connected to the other end of the rotating shaft, and adopts a cuboid frame structure. Two parallel screw rods are connected between the inner walls, parallel to each other, of the rotating frame. The screw rods are parallel to the rotating shaft. A first sliding block is mounted on the screw rods, and adopts a cuboid structure. Two second through holes are formed in one side, close to the first fixed plate, of the first sliding block. The screw rods are mounted in the second through holes. A first hydraulic cylinder is connected to one side, far from the first fixed plate, of the first sliding block, and is fixed to one side, far from the first fixed plate, of the rotating frame. The mechanical arm has the advantages that the utilization rate of the operation space is high, the processing efficiency is improved, and the safety of an operator is protected.

Description

technical field [0001] The invention relates to the technical field of mechanical arms, in particular to a mechanical arm applied to injection molding machines. Background technique [0002] The mechanical arm of the injection molding machine is mainly to simulate certain movement functions of the human hand and arm, and is used to grab and carry the finished products and materials of the injection molding machine according to a fixed program. It can replace the heavy labor of people to realize the mechanization and automation of production, and can operate in harmful environments to protect people's safety. [0003] Traditionally, manpower is mainly used to grab and carry the finished products and material ends of the injection molding machine. Sometimes the removed finished products will have a great impact on the quality of the finished parts due to the unfixed time of taking them. At the same time, due to the injection molding The finished product and material head of t...

[0003] Traditionally, manpower is mainly used to grab and carry the finished products and material ends of the injection molding machine. Sometimes the removed finished products will have a great impact on the quality of the finished parts due to the unfixed time of taking them. At the same time, due to the injection molding The finished product and material head of the machine have a certain temperature, and sometimes it will cause certain injuries to the operator due to improper operation; some manipulators used in modern times are generally in the form of a single arm, which requires a large space for operation, but in practice In the work, due to the small control space around the injection molding machine, it is difficult for such a manipulator to play well
