Ejection Rods: The relevant function of ejector pins in injection molds

The sprue puller, also known as the ejector pin in an injection mold, plays a crucial role. In thermoplastic injection molds, there's typically a cold material well. Its function is to store cold material at the nozzle tip during the injection interval, preventing it from entering the cavity and affecting the quality of the plastic parts. However, after opening the mold, the cold material stored in the cold well must be ejected along with the plastic part via the sprue puller to facilitate injection molding in the next cycle.

What to do if the Corinthian column balance fails? Are there any solutions?

Tie bars are rod-like components installed in machinery or buildings that provide a pulling function. The principle is to balance the sliding of the template and withstand the tension caused by clamping. They are an important component of the injection molding industry. In clamping machines, the performance of tie bars directly affects the rigidity and stability of the system. Only by improving the structural characteristics of tie bars can the rigidity and stability of the system be effectively improved.

Correcting the Gollin column: How to correct the Gollin column of an injection molding machine

For adjustments to the Gollin column, if it's a self-adjustment, suitable molds are usually installed on the machine. After locking, a percentage gauge is used to measure the distance between the four columns, and then the mold is opened to adjust the nuts on the top plate to achieve adjustment. However, this method is suitable for major repairs of the Gollin column. Second-hand machines will have some error traces.

The importance and methods of Corin column maintenance

The maintenance methods for Colin columns are very important, but if the methods are incorrect, there will still not be much effect. In other words, only reasonable maintenance can help extend the service life of the Colin column. Even simple oiling requires very specific methods. A Colin column is a rod-like component installed on machinery or buildings, playing a traction role. The principle is to balance the sliding of the template and withstand the tension caused by clamping. It is an important component of the injection molding industry.

$Reasons for and solutions to the fracture of Corinthian columns$

Reasons for and solutions to the fracture of Corinthian columns

We all know that during engineering use, Gorlin columns are more prone to breakage than fully hydraulic tie rods. So why are Gorlin columns prone to breakage? In the design of Gorlin columns, because of the need to consider system rigidity, the tie rod diameter is usually relatively large. But surprisingly, such tie rods are more prone to breakage, especially in industries that produce materials with high fluidity and large forming areas, such as videotape boxes, plastic cutlery, etc. Because of their production speed requirements, frequent breakage of Gorlin columns can occur, even causing damage to the molds.

Meltblown fabric extruder operating procedure

After completing the safety check and confirming that everything is correct, the meltblown fabric extruder can perform the following operations: (1) Engage the clutch and manually rotate the pulley 4-5 turns to check for any foreign objects inside the equipment and any jamming. (2) For vacuum extruders, check the mixing section using the same method. (3) After confirming that the above parts are correct, open the clutch before starting the main motor. If the extruder uses an oil pump for forced lubrication, start the lubricating oil pump first, then start the main motor. After the main motor reaches normal speed, engage the clutch and let the entire

Inspection before using meltblown fabric extruder

Many people don't understand the key points before operating a meltblown fabric extruder. Today, let's introduce them, starting with the key operating points. 1. For a new extruder that has not been used, after installation, a comprehensive inspection should be carried out first. (1) Check if all fasteners have been tightened. (2) Check if all lubrication points have been filled with sufficient lubricating oil or grease.

Understanding the difference between chrome-plated bars and polished bars

Many rod-like tubes and steel products surround us. Their surfaces are quite similar, resembling round steel, such as chrome-plated rods, hardened shafts, silver steel bars, polished rods, and bright round iron. Today, let's discuss the difference between these and polished rods:
