What is the difference between a tube and a thimble?

Both the cylinder and the thimble are one of the plastic mold parts. The cylinder thimble is a common thimble in the cylinder needle assembly, and they are all metal rods for fixing plastic products. With the cylinder and thimble, the product can be continuously ejected in the high-speed running mold, and the production efficiency of the product can be improved. So, what is the difference between a tube and a thimble?

First of all, the difference between the cylinder and the thimble is that they are two completely different mold parts. From their appearance, the cylinder is hollow, the standard thimble is solid, and long and has a sharp tip, while the material of the cylinder is relatively biased. hard. Secondly, the thimble barrel is composed of two parts, the barrel is the inner tube and the thimble, and the inner needle can move on the thread. When the inner needle is fixed on the bottom plate of the mold, the cylinder is installed on the top of the thimble plate. When it is ejected, the cylinder will also move up with the thimble.

Finally, the difference between the cylinder and the thimble is also different from the name. The cylinder and the thimble can be used together and are called the cylinder needle assembly. The cylinder of the cylinder needle assembly is also called a jacking tube or a hollow thimble, and it can also be divided into a straight cylinder, a stepped cylinder, and so on. The thimble is often referred to as a cradle, a pin and so on.
