Description

A ball linear slider for linear guides Technical Field

[0001] This utility model relates to the field of guide rail slider technology, specifically a ball linear slider for linear guide rails. Background Technology

[0002] A slider is a mold component that can slide perpendicular to the mold opening and closing direction or at a certain angle to the mold opening and closing direction during the mold opening action. When the product structure makes it impossible for the mold to demold normally without a slider, a slider must be used. The material itself has appropriate hardness and wear resistance, which is sufficient to withstand the friction of movement. However, existing connecting parts are generally installed and fixed with the slider by bolts.

[0003] In the existing process of installing the connector with the slider, it is necessary to first align the holes and slots on the connector with the threaded grooves at the top of the slider, and then connect the connector to the slider threadedly by passing the bolts through the holes and slots. This method results in excessive time being spent aligning the holes and slots with the threaded grooves during the installation of the connector. Furthermore, if the connector is pulled during the alignment process, causing the holes and slots to become misaligned with the threaded grooves, the bolts will misalign with the threads during the tightening process, thus making the installation of the connector time-consuming. To address this issue, we propose a ball linear slider for linear guides. Technical issues

[0004] The purpose of this utility model is to solve the problem that misalignment between the connector and the slider can easily lead to misalignment of the bolt and the thread groove, resulting in a long installation time for the connector, and to provide a ball linear slider for linear guide rails.

Beneficial effects

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] By setting up a positioning mechanism, rotating the adjusting bolt drives the moving push block to press the lifting push plate upward. At this time, the lifting push plate pushes the positioning cylinder upward, and then the connector is placed on the upper surface of the slider body. The corresponding holes and slots of the connector and the positioning cylinder are fitted into the positioning cylinder to facilitate the connection and positioning of the connector and the slider body. Then, rotating the fixing bolt through the threaded connection between the connector and the positioning cylinder allows for quick fixation of the connector and the slider body. When the connector is disassembled for maintenance, rotating the fixing bolt sequentially disengages it from the positioning cylinder and the connector. Then, rotating the adjusting bolt reverses the above operation, allowing for quick storage of the positioning cylinder, thus achieving the purpose of convenient disassembly and assembly of the connector.
