Guiding structure of slide block positioning insert

Abstract

The invention provides a guiding structure of a slide block positioning insert. Through the guiding structure, in a core-pulling process of a slide insert, wear between the slide insert and a guiding hole is avoided, a mold positioning precision is guaranteed and product quality is improved. The guiding structure comprises a front mold, a rear mold, an A plate and a B plate. A cavity is arranged between the front mold and the rear mold. The slide insert is arranged in the cavity at the corresponding side. The guiding structure is characterized in that an outer side of the slide insert is provided with a guiding block; the guiding block is provided with a guiding hole; the middle of the slide insert passes through the guiding hole; a guide sleeve is sleeved between the guiding hole and the slide insert; the guiding block is inserted in a groove formed from the front mold, the rear mold and the B plate; the guiding block is supported by the B plate; the tail end of the slide insert is installed in locating slots of a connection block and a straight slide block; the connection block is fixedly connected to an inner side of the straight slide block; the bottom end surface of the straight slide block is supported by an upper plane of a wear-resistant block; and a lower end plane of the wear-resistant block is fixedly connected to the B plate.

Description

technical field [0001] The invention relates to the structural technical field of product molds, in particular to a guiding structure for positioning inserts of row blocks. Background technique [0002] The existing row inserts are installed in the positioning grooves of the connecting block and the row block through their tail structure. During the demoulding process, the front end of the row insert is supported in the guide hole of the guide block, but Due to gravity, the row inserts will rub against the guide holes. Over time, both will wear, which will affect the positioning accuracy of the mold and reduce the quality of injection molded products. Contents of the invention [0003] The invention provides a guide structure for positioning inserts of row blocks, which prevents friction between the row inserts and guide holes during the core-pulling process of the row inserts, ensures the positioning accuracy of the...
