Description

Technical Field

[0001] The utility model relates to the technical field of pulling and positioning, in particular to a guiding and positioning mechanism for pulling materials of a plastic mold. Background Technique

[0002] LCG plastic is in the form of a very long strip, and a number of processing positions are equidistantly distributed thereon. Each processing position needs to be molded on the mold pressing condition of the mold. In the prior art, one end of the strip-shaped LCG plastic tape is directly placed on the mold pressing condition of the mold by manual for molding. After processing, the worker moves the processed processing position backward from the rear end of the mold pressing condition, and at the same time moves the adjacent processing position to be processed onto the mold pressing condition, thus forming an assembly line type molding processing production line.

[0003] After retrieval, Chinese Patent Publication (Announcement) No. CN 209937483 U discloses a pulling mechanism at the rear end of an LCG plastic mold, which solves the problems in the prior art that the human force is used to align the processing position of the LCG plastic tape to be processed with the mold pressing condition, resulting in large errors, many molding defective products, ultimately increasing the molding production cost, and high labor cost. The utility model can effectively make the LCG plastic tape be on the same horizontal plane as the mold pressing condition when being pulled away from the mold pressing condition, and accurately pull the processed processing position of the LCG plastic tape backward, so that the next batch of processing positions to be processed are accurately aligned with the mold pressing condition, effectively reducing defective products, ensuring the yield of molding processing, and at the same time reducing labor cost, so as to generally reduce the production cost of LCG plastic mold molding processing. However, when the comparative document is specifically used, when the pulling device pulls the material to a certain extent, it occupies a certain space area, and a structure that can be positioned and conveniently retracted when not in use is needed to reduce the occupied space area. Therefore, it is necessary to design a guiding and positioning mechanism for pulling materials of a plastic mold. Content of the Utility Model
