Several Commonly Used Mold Button Machine Structures, I Will Explain Them All To You Today!

In the structure of secondary parting, secondary ejection and front die ejection, the button machine component is often used to control the mold opening sequence and mold opening stroke of each template.



The function of the buckle machine is similar, but it is divided into various structures. According to the characteristics of the buckle machine itself, it is necessary to select the buckle machine reasonably in different occasions. Below we explain several commonly used buckle machine structures.

1. Datong deduction machine

1. Advantages: The Datong buckle machine has a simple and compact structure, and the processing volume of the mold base is not large. It can be installed on the mold at will, and the installation takes up a small space, thereby reducing the chance of interference with other parts on the mold base. The method of controlling the mold opening stroke is more flexible, which can be realized by adding a limit stop on the mold base, and the price is relatively cheap.

2. Disadvantages: The Datong buckle machine relies on the slingshot to press the steel ball and the control rod to achieve locking, so the tightening force is not easy to control, and the phenomenon of decoupling before the required stroke occurs, the reliability is not high, and it is also Not easy to adjust.

3. Applicable occasions: This type of buckle machine is used for small and medium-sized molds, where the required tightening force is not large, and the reliability requirements are not very high. Due to low reliability, this form is generally not used. As shown in Figure 1, it is used for the secondary ejection of the ejector plate.



Matters needing attention: The Datong buckle machine relies on the slingshot to press the steel ball and the control rod to achieve locking, so the tightening force is not easy to control, and it is only suitable for small and medium-sized molds with little tightening force requirements.

2. HASCO buckle machine:

1. Advantages: HASCO buckle machine has many specifications and a wide range of options; mechanical locking, safe and reliable locking, convenient installation, and small processing volume of mold base, the length of the control rod and hook can be adjusted according to the actual situation, the price Moderate.

2. Disadvantages: After the pin holes and screw holes for installation are determined, they need to be reprocessed. After the mold opening stroke is determined by the design, it is not easy to change and the mold opening stroke range is limited by the length of the control rod.

3. Applicable occasions: mechanical locking, safe and reliable locking, suitable for all kinds of large, medium and small molds.

Matters needing attention: The mold opening stroke is determined by design, the control stroke is not easy to change after the pin hole and screw hole position is processed, and the mold opening stroke range is limited by the length of the control rod.



3. STRACK button machine:



1. Advantages: mechanical locking, safe and reliable locking; changing the relative position between the control rod and the hook can meet the requirements of a large stroke range, after installation, the mold opening stroke can still be adjusted by moving the adjustment block on the control rod.

2. Disadvantages: It takes up a lot of space, the installation is complicated, the processing volume of the mold base is large, and the price is more expensive.

3. Applicable occasions: It is suitable for larger molds and can meet the needs of larger mold opening strokes. Due to the high price, it is generally not used unless the customer has special requirements.

Note: After installation, the mold opening stroke can still be adjusted by moving the adjustment block on the control rod.

Four, RABOURDIN button machine:

1. Advantages: Mechanical locking, large fastening force, safe and reliable, the biggest advantage is that the mold opening stroke can be adjusted by the adjustment block after installation, which can meet the requirements of a large stroke range.

2. Disadvantages: It occupies a large space, the processing volume of the mold base is large, the installation is complicated, and the price is relatively expensive.

3. Applicable occasions: It is suitable for larger molds and requires larger mold opening strokes. Due to the high price, it is generally not used unless the customer has special requirements.



Precautions:



After installation, the mold opening stroke can still be adjusted by moving the adjustment block on the control lever.
