3 functions of Pins and how to use them

Pins, as the name suggests, are parts that are mainly used to limit the free movement of items in space. Pins are composed of a shaft body and positioning heads fixed at both ends of the shaft body and are usually installed in the positioning hole of the fixture or mold by pressing in, to realize rapid positioning and precise position control of parts. Next, let's take a look at the 3 functions and usage methods of Dowel pins.

What are the 3 functions of Pins?

The function of Pins is to limit the free movement of items. Specifically, Pins mainly have the following functions:

1. Positioning: In a mold composed of two or more parts, the positioning surfaces of two adjacent parts of the mold are accurately positioned to ensure the integrity of each part of the mold.

2. Pre-tightening: The distance between the mold parts can be adjusted through the length of the Custom pins or the degree of expansion and contraction, and the mold parts can be pre-tightened to ensure that the mold does not loosen during the working process.

3. Steady: Use the matching precision between Pins and positioning holes to ensure the stability and rigidity of the mold, and avoid unstable work due to vibration.

How to use Pins.

The use of Pins is very simple, just press the Pins into the holes. Specific steps are as follows:

1. Find the correct and suitable Pins in the positioning holes of the jig or mold.

2. Align the head of the Ejector pins with the positioning hole, and press the Pins into the hole with light force.

3. Ensure the matching accuracy between the Pins and the positioning hole, and avoid affecting the positioning accuracy due to the gap.

4. Confirm whether the length or degree of expansion of Pins meets the design requirements, and make adjustments as required.

5. Check whether the Pins are installed correctly to ensure positioning accuracy and reliability.

It should be noted that when using Pins, appropriate specifications and models should be selected according to the actual situation to meet different positioning requirements. At the same time, Guide pins with excellent material, smooth surfaces, and high precision should be selected to ensure positioning accuracy and service life.

In short, Pins are a simple and practical component, which is widely used in fixtures, molds, and other equipment in industrial production and manufacturing, providing accurate and fast positioning support for it, and is an indispensable part of modern machining technology.
