Description

Technical Field

[0001] The utility model relates to the technical field of guide rail sliders, in particular to an external dual-axis guide rail slider. Background Art

[0002] Linear guides are also called line rails, slide rails, linear guides, and linear slides. They are used in high-precision or high-speed linear reciprocating motion occasions, and can bear a certain torque. They can achieve high-precision linear motion under high loads. Linear guides are generally equipped with sliders for use. The slider is a mold component that can slide perpendicular to the opening and closing direction or at a certain angle to the opening and closing direction during the mold opening action. When the product structure makes it impossible for the mold to be demolded normally without the use of a slider, a slider must be used. The material itself has appropriate hardness and wear resistance, enough to withstand the friction of movement. The hardness of the cavity part or core part on the slider should be at the same level as the other parts of the cavity and core.

[0003] In the prior art, the guide rail slider is provided with a dustproof sheet on its end face to prevent dust from entering the slider. However, the friction between the dustproof sheet and the guide rail will cause wear, thereby reducing the sealing performance. The traditional method is to replace the dustproof sheet in time. In the prior art, the replacement of the dustproof sheet is very inconvenient.

[0004] Therefore, how to provide an external dual-axis guide slider to solve the problems existing in the prior art is of great significance to its application. Utility Model Content

[0005] In view of this, the purpose of the present application is to provide an external dual-axis guide slider to solve the problem.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] An external dual-axis guide rail slider comprises a slider body, a pulley, an end cover, a fixing screw and a dustproof sheet;

[0008] The pulley is installed inside the slider body, the end cover is installed on both ends of the slider body through fixing screws, both sides of the end cover are provided with fixing grooves on one side close to the slider body, and the dustproof sheet is installed inside the fixing grooves.

[0009] Preferably, both ends of the dustproof sheet are provided with a slot, the slot is dovetail-shaped, and the surface of the pulley is provided with a dovetail-shaped groove.

[0010] Preferably, a positioning column is fixedly connected to the middle of the fixing groove, a positioning hole is opened in the middle of the dustproof sheet, and the positioning column and the positioning hole are matched.

[0011] Preferably, the dustproof sheet is made of rubber, and the thickness of the fixing groove is equal to the thickness of the dustproof sheet.

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

[0013] 1. Both ends of the dustproof sheet in the utility model can be used. When one end is worn out, the other end can be replaced to continue to seal the slider, which has a longer service life and is more economical and durable.

[0014] 2. When the dustproof sheet is turned, the fixing screws of the end cover are removed, and the dustproof sheet is taken out from the fixing groove. After rotating 180 degrees, the unworn slot of the dustproof sheet is placed inward to complete the turning. The utility model is simple and convenient to use.
