The working principle of pogo pin spring thimble

　　When using the pogo pin spring thimble, the pogo pin and the thimble hole rub against each other, the thimble will burn out or wear out, the thimble hole will wear more, the product thimble will peel off, and even broken pins will appear. phenomenon that affects the quality or assembly of the product. Therefore, we must regularly and regularly spray the pogo pin pogo pin on the pogo pin pogo pin for lubrication. So what is the principle of using pogo pin spring thimble?

　　The ejector pins should be arranged so that the ejection force is as balanced as possible. The demolding force required for complex structures is large, and the number of sleeves should be increased accordingly.

　　Thimbles should be placed in effective parts, such as bones, columns, steps, metal inserts, local thick glue and other complex structures. The apical pins on either side of the bone position and the column position should be arranged as symmetrically as possible. The distance between the thimble and the bone position and the position of the post position is usually D = 1.5mm. Make sure that the centerlines of the ejector pins on both sides of the post location pass through the center of the post location.

　　Avoid thimbles on steps or sloping surfaces. The top surface of the thimble should be as flat as possible. The thimble should be placed on the structural part with good force.

　　Flat thimbles should be used when the rubber part has a deep bony location (depth ≥ 20 mm) or when it is difficult to deploy a dome thimble. When a flat thimble is required, the flat thimble should be in the form of an insert for ease of processing.

　　Avoid sharp point steel, thin steel, especially the top surface of the thimble, must not touch the front die surface.

　　The thimble arrangement should consider the edge spacing between the thimble and the water delivery channel to avoid affecting the processing and water leakage of the water delivery channel.

　　Considering the exhaust function of the ejector pin, in order to discharge the ejector, the ejector pin should be placed in a part where a vacuum is easily formed. For example, at the large plane of the cavity, despite the small packing force of the rubber part, a vacuum tends to form, which leads to an increase in the release force.

　　For plastic parts with appearance requirements, the thimble should not be placed on the design surface, and other spraying methods should also be used.

　　For clear plastic parts, thimbles cannot be placed where light is required.

　　Choose a thimble with a larger diameter. That is, with sufficient injection locations, a larger diameter and size preferred thimble should be used.

　　The gauge of the thimble should be as small as possible. When using thimbles, thimbles should be sized to minimize size and size, and the preferred size series should be used whenever possible.

　　The selected thimble should meet the requirements of ejection strength. When ejecting, the thimble should bear a lot of pressure. In order to avoid the bending deformation of the small thimble, when the diameter of the thimble is less than 2.5mm, the thimble should be selected.
