Reset Extrusion

Reset Extrusion Components Supplier

DGMF Mold Clamps Co., Ltd is the Reset Extrusion Components supplier and mould clamps manufacturer in China.

Due to injection molds and die-casting molds, a secondary ejection is required during the special demolding process, and a reset extrusion mechanism is required to complete its function.

The second ejection of the mold is generally used for molds with complex product structures, which is to fix the ejector pin with two ejector plates.

The ejector pin moves forward at the same time when demolding, and the secondary ejector pin will continue to move forward when the primary ejection position is limited until the product drags down.

Where is the second ejection of the mold usually used?

1. Due to the special shape of the finished product, or the requirements of mass production;

If the finished product is still in the mold cavity after one ejection, or cannot fall off automatically.

2. Part of the ejection stroke requires a larger product.

The use of a secondary ejection reset extrusion mechanism can reduce the force exerted by the ejector pin during ejection and avoid product defects during ejection.

3. The forming time of the finished product is required to be longer.

The working principle of the secondary ejection injection machine

In short, the reset extrusion components can be divided into the following three categories.

1. Secondary ejection mechanism with a single ejector pin plate combination

The so-called single ejector pin board combination is a common single set of ejector pin board combinations (one for the upper ejector pinboard and one for the lower ejector pinboard).

Since there is only a single set of thimble board combinations, the ejection action of the injection machine only provides the traditional one-time ejector out; another ejection must be carried out in conjunction with other mold component mechanism designs (such as mold springs).

2. Reset extrusion mechanism of double ejector pin plate combination

First, all the ejector plates are simultaneously ejected together. After ejecting to the set position, a part of the ejector plates stop ejecting and the remaining ejector plates continue to eject until the ejection is completed.

3. Pneumatic/hydraulic reset extrusion mechanism

A pneumatic/hydraulic secondary ejection mechanism is additionally installed outside the mold.

Reset extrusion applications

1. Due to the special shape of the finished product, or the requirements during mass production;

If the finished product is still in the mold cavity after one ejection, or cannot fall off automatically;

2. Part of the ejection stroke requires a larger product.

The use of secondary ejection can reduce the force applied by the ejector pin during ejection and avoid product defects during ejection.

3. When the forming time of the finished product is required to be longer

What are the advantages of the reset extrusion mechanism of the mold?

1. Effectively solve the function of the reset extrusion mechanism in the special demolding process.

2. The mechanical interlocking design is safe and reliable. The ejector device comes with a flange ring and connecting bolts for easy installation.

3. The self-locking function of the flange makes it convenient to fasten the outer braces. Various specifications are suitable for different sizes of mold load requirements.

4. Accurate installation is required (an ejector device is generally installed on a set of molds), and the stroke must be calculated accurately to avoid damage to the product.
