Description

Technical Field

[0001] The invention relates to the technical field of injection molding, in particular to an automatic feeding mechanism for injection molding. Background Art

[0002] The pre-embedding treatment of plastic parts is a very important operation step in the injection molding process. In some injection molding production, the embedding of nuts is also a very common production process. Through pre-embedding, the aesthetics and structural stability of the product can be improved after injection molding. During injection molding, a product shell generally requires multiple nuts to be pre-embedded. At present, the pre-embedded injection-molded nuts are usually loaded one by one through a vibration plate, and multiple nuts are loaded onto a pallet. Then, the nuts on the pallet are directly put onto the injection mold by a robot, and then injection molding is performed.

[0003] In order to facilitate the loading of the robot, the position of the limit nut hole on the pallet is generally the same as the position where the nut needs to be embedded on the shell. In this way, when in use, the robot can directly grab multiple nuts at the same time for loading. However, since different products require different positions of embedded nuts, and the position of the limit nut holes on a pallet is fixed, one pallet can only limit the nuts of one product, thereby reducing the practicability of the device.

[0013] 2. The present invention, through the arrangement of push rods, slots, insert rods and other structures for use in conjunction, when in use, the push rod can be started, so that the push rod pushes the frame to move upward, and the upwardly moved frame drives the cross bar, the insert rod and other structures to move upward, and after the insert rod moves up to a certain position, the insert rod is inserted into the slot, so that the insert rod can limit the connection block to ensure the accuracy of the position of the connection block.
