Push rod refers to the part that pushes the product out of the mold.
In order to eject the molded product tightly attached to the cavity, it is necessary to set the push rod with appropriate thickness in a balanced way. When the push rod is pushed out, it may break or bend due to compressive stress. In order to prevent this phenomenon, the push rod needs to have sufficient compressive strength and bending strength. In addition, when the push rod reciprocates, it is easy to wear, so it is necessary to use wear-resistant materials and enhance the surface hardness.
The surface of the push rod needs to be smooth and smooth, and good diameter accuracy must be guaranteed.
Push rod is a plastic mould accessory, which is used in plastic mould. Push rod can also be called thimble, insert needle, middle needle, support needle, etc.
